随着显示面板技术的不断发展，OLED(OrganicLight-EmittingDiode，有机电致发光二极管)器件以及其他发光器件已经逐步应用于手机、平板、笔记本等各种显示面板产品中。With the continuous development of display panel technology, OLED (Organic Light-Emitting Diode, organic electroluminescent diode) devices and other light-emitting devices have been gradually applied to various display panel products such as mobile phones, tablets, and notebooks.
显示面板中包括不同出光颜色的发光子像素，显示面板的电源能够为驱动芯片提供默认驱动电压AVDD，驱动芯片在接收到默认驱动电压后，能够利用默认驱动电压与其他相关电压生成显示驱动过程中所需的各种电压。例如，驱动芯片利用默认驱动电压生成的电压可以包括但不限于扫描信号的高电平有效信号VGH、数据信号的两个参考电平VGSP、VGMP、初始化电压Vref、数字电压信号OVDD等电压信号的其中一种或多种。The display panel includes light-emitting sub-pixels with different light-emitting colors. The power supply of the display panel can provide the default driving voltage AVDD for the driver chip. After receiving the default driving voltage, the driver chip can use the default driving voltage and other related voltages to generate a display. various voltages required.

通常情况下，为了保障显示面板的整体显示效果，需要尽可能地增大默认驱动电压，以使驱动芯片利用默认驱动电压生成的相关电压信号足以满足显示驱动过程中各种电压信号的最低需求。然而，显示面板长时间提供较大的默认驱动电压将会导致显示面板的屏体显示功耗较高。Usually, in order to ensure the overall display effect of the display panel, it is necessary to increase the default driving voltage as much as possible, so that the relevant voltage signals generated by the driver chip using the default driving voltage are sufficient to meet the minimum requirements of various voltage signals in the display driving process. However, if the display panel provides a larger default driving voltage for a long time, the power consumption of the screen body of the display panel will be higher.
为了解决上述技术问题，本申请实施例提供了一种显示面板的驱动电压调整方法、装置及设备。下面首先对本申请实施例所提供的显示面板的驱动电压调整方法进行介绍。In order to solve the above technical problems, embodiments of the present application provide a method, device and equipment for adjusting a driving voltage of a display panel. Firstly, the method for adjusting the driving voltage of the display panel provided by the embodiment of the present application will be introduced below.
图1示出了本申请一个实施例提供的显示面板的驱动电压调整方法的流程示意图。显示面板的驱动电压调整方法包括：FIG. 1 shows a schematic flowchart of a method for adjusting a driving voltage of a display panel provided by an embodiment of the present application. The method for adjusting the driving voltage of the display panel includes:

本申请实施例中提供的显示面板的驱动电压调整方法，可以应用于显示面板的驱动电压调整装置中，该装置可以根据待显示的图像画面的颜色类型调整默认驱动电压，以在不影响未缺色(即需要发光)的发光子像素对应显示面板的发光子像素的正常发光的前提下，降低默认驱动电压AVDD，节省显示功耗。该显示面板可以是PC、电视、智能终端或者平板电脑等等。本实施例中不对显示面板的具体形式进行限定。显示面板的子像素与显示画面的子像素对应。The method for adjusting the driving voltage of the display panel provided in the embodiment of the present application can be applied to the device for adjusting the driving voltage of the display panel. Under the premise that the light-emitting sub-pixels of the same color (that is, need to emit light) correspond to the normal light-emitting of the light-emitting sub-pixels of the display panel, the default driving voltage AVDD is reduced to save display power consumption. The display panel may be a PC, a TV, a smart terminal or a tablet computer, and the like. The specific form of the display panel is not limited in this embodiment. The sub-pixels of the display panel correspond to the sub-pixels of the display screen.
在本实施例中，显示面板可以根据待显示的图像画面的图像数据，确定该图像画面对应的颜色类型。至少两种不同颜色类型的图像画面对应的默认驱动电压不同。根据图像画面对应的颜色类型，可以相应调整提供给驱动芯片的默认驱动电压。以显示面板包括红、绿、蓝三种发光子像素为例，为了使得三种颜色的发光子像素均能够正常发光，默认驱动电压需要设置为满足三种颜色的发光子像素正常发光所需的最低驱动电压。而在图像画面的颜色类型不包括所有颜色时，默认驱动电压可以进行相应降低，以在需要发光的发光子像素仍能够正常发光的前提下，通过降低驱动电压实现显示功耗的减小。In this embodiment, the display panel may determine the color type corresponding to the image frame according to the image data of the image frame to be displayed. Default driving voltages corresponding to image frames of at least two different color types are different. According to the color type corresponding to the image screen, the default driving voltage provided to the driver chip can be adjusted accordingly. Take the display panel including red, green, and blue light-emitting sub-pixels as an example. In order to enable the light-emitting sub-pixels of the three colors to emit light normally, the default driving voltage needs to be set to meet the requirements for the light-emitting sub-pixels of the three colors to emit light normally. Minimum drive voltage. When the color type of the image screen does not include all colors, the default driving voltage can be reduced accordingly, so that the display power consumption can be reduced by reducing the driving voltage on the premise that the light-emitting sub-pixels that need to emit light can still emit light normally.
在S110中，显示面板可以根据待显示的图像画面的图像数据，确定待显示的图像画面对应的颜色类型。In S110, the display panel may determine the color type corresponding to the image frame to be displayed according to the image data of the image frame to be displayed.
显示面板中通常包括不同出光颜色的发光子像素，例如可以包括红色、绿色、蓝色三种发光子像素，也可以包括红色、绿色、蓝色以及白色四种发光子像素或者红色、绿色、蓝色以及黄色四种发光子像素，对于发光子像素的颜色类别在此不做限制。The display panel usually includes light-emitting sub-pixels of different light-emitting colors. For example, it may include three light-emitting sub-pixels of red, green, and blue, or four light-emitting sub-pixels of red, green, blue, and white, or red, green, and blue light-emitting sub-pixels. There are four light-emitting sub-pixels of yellow and yellow, and there is no limitation on the color category of the light-emitting sub-pixels.
根据待显示的图像画面的图像数据，显示面板可以确定待显示的图像画面中，需要发光的一部分发光子像素分别对应的出光颜色，并根据发光子像素的出光颜色，确定该图像画面的颜色类型。例如，显示面板根据待显示的图像画面的亮度数据，确定该图像画面中仅红色发光子像素需要发光，其余出光颜色的发光子像素不需要发光，或者其余出光颜色的发光子像素均为0灰阶，则显示面板可以确定该图像画面的颜色类型为纯红色图像画面。同样地，图像画面的颜色类型还可以为纯蓝色图像画面、纯绿色图像画面、两种颜色混合的图像画面、三种颜色混合的图像画面等等。According to the image data of the image frame to be displayed, the display panel can determine the light emitting colors corresponding to part of the light-emitting sub-pixels that need to emit light in the image frame to be displayed, and determine the color type of the image frame according to the light-emitting colors of the light-emitting sub-pixels . For example, the display panel determines according to the brightness data of the image frame to be displayed that only the red light-emitting sub-pixels in the image frame need to emit light, and the light-emitting sub-pixels of other light-emitting colors do not need to emit light, or the light-emitting sub-pixels of other light-emitting colors are all 0 gray. level, the display panel can determine that the color type of the image frame is a pure red image frame. Likewise, the color type of the image frame may also be a pure blue image frame, a pure green image frame, an image frame of two colors mixed, an image frame of three colors mixed, and so on.
作为一种可选的实施例，上述不同颜色类型的图像画面对应的颜色种类不同。As an optional embodiment, the above image frames of different color types correspond to different color types.
例如，图像画面的颜色类型为纯红色时，该图像画面对应的颜色种类为红色；图像画面的颜色类型为红蓝混合时，该图像画面对应的颜色种类为红色和蓝色。即，在两个图像画面对应不同颜色类型时，两个图像画面所包含的颜色并不相同。For example, when the color type of the image frame is pure red, the corresponding color type of the image frame is red; when the color type of the image frame is mixed red and blue, the corresponding color types of the image frame are red and blue. That is, when two image frames correspond to different color types, the colors contained in the two image frames are not the same.
请参照图2，作为一种可选的实施例，上述S110，可以包括：Please refer to FIG. 2, as an optional embodiment, the above S110 may include:

在S210中，显示面板可以根据待显示的图像画面的图像数据确定该单个图像画面中各个颜色的发光子像素的发光比例。In S210, the display panel may determine, according to the image data of the image frame to be displayed, the light-emitting ratio of the light-emitting sub-pixels of each color in the single image frame.
作为一种可选的实施方式，确定发光比例的方式可以是根据图像数据确定各个发光子像素的发光亮度，并根据发光亮度与发光阈值的大小来确定各个发光子像素是否为发光状态。例如，单个图像画面中，某个发光子像素的发光亮度高于发光阈值，则可以确定发光子像素在该图像画面中为发光状态。反之则确定该发光子像素为非发光状态。As an optional implementation, the manner of determining the light emitting ratio may be to determine the light emitting brightness of each light emitting sub-pixel according to the image data, and determine whether each light emitting sub pixel is in a light emitting state according to the light emitting brightness and the light emitting threshold. For example, in a single image frame, if the light-emitting brightness of a certain light-emitting sub-pixel is higher than the light-emitting threshold, it may be determined that the light-emitting sub-pixel is in a light-emitting state in the image frame. Otherwise, it is determined that the light-emitting sub-pixel is in a non-light-emitting state.
在根据图像数据分别确定每个发光子像素的发光状态后，可以对处于发光状态的发光子像素分别按照不同颜色进行计数，以得到该图像画面中，每种颜色的发光子像素的发光数量。根据每种颜色的发光子像素的发光数量以及处于发光状态的发光子像素的总数量，即可计算得到各个颜色的发光子像素的发光比例。After the light-emitting state of each light-emitting sub-pixel is determined according to the image data, the light-emitting sub-pixels in the light-emitting state can be counted according to different colors, so as to obtain the light-emitting quantity of each color of light-emitting sub-pixels in the image frame. According to the number of light-emitting sub-pixels of each color and the total number of light-emitting sub-pixels in a light-emitting state, the light-emitting ratio of the light-emitting sub-pixels of each color can be calculated.
请参照图3，作为一种可选的实施例，上述S210，可以包括：Please refer to FIG. 3, as an optional embodiment, the above S210 may include:

在本实施例中，显示面板可以根据图像画面的图像数据，确定各个发光子像素的亮度数据，并根据亮度数据是否满足发光阈值，确定各个发光子像素在该图像画面中是否为发光状态。对图像画面中每种颜色的发光子像素的发光数量进行统计后，可以根据每种颜色的发光数量以及发光总数量计算得到各个颜色的发光子像素的发光比例。In this embodiment, the display panel may determine brightness data of each light-emitting sub-pixel according to the image data of the image frame, and determine whether each light-emitting sub-pixel is in a light-emitting state in the image frame according to whether the brightness data satisfies the light-emitting threshold. After counting the number of light-emitting sub-pixels of each color in the image frame, the light-emitting ratio of the light-emitting sub-pixels of each color can be calculated according to the light-emitting number of each color and the total number of light-emitting.
在S310中，显示面板在显示单个图像帧的画面前，需要获取图像画面的图像数据，根据该图像数据可以确定各个颜色的发光子像素的亮度数据。In S310, the display panel needs to acquire image data of the image frame before displaying the image of a single image frame, and according to the image data, the luminance data of the light-emitting sub-pixels of each color can be determined.
在S320中，在单个图像画面中，遍历各个颜色的发光子像素的亮度数据，可以按照发光子像素的颜色对亮度数据进行划分，以得到每种颜色下达到发光阈值的亮度数据的数量，进而确定每种颜色的发光子像素分别对应的发光数量。In S320, in a single image frame, the luminance data of the luminous sub-pixels of each color may be traversed, and the luminance data may be divided according to the color of the luminous sub-pixels, so as to obtain the quantity of luminance data reaching the luminous threshold for each color, and then Determine the luminous quantities corresponding to the luminous sub-pixels of each color.
以红色发光子像素为例，在单个图像画面中，根据各个红色发光子像素的亮度数据，可以确定亮度数据达到发光阈值的红色发光子像素的数量，即红色发光子像素在该图像画面中的发光数量。同样地，还可以分别确定绿色发光子像素以及蓝色发光子像素在该图像画面中的发光数量。Taking red light-emitting sub-pixels as an example, in a single image frame, according to the brightness data of each red light-emitting sub-pixel, the number of red light-emitting sub-pixels whose brightness data reaches the light-emitting threshold can be determined, that is, the number of red light-emitting sub-pixels in the image frame Luminous amount. Similarly, the light emitting quantities of the green light-emitting sub-pixels and the blue light-emitting sub-pixels in the image frame can also be determined respectively.
在一种可选的实施方式中，显示面板的驱动芯片中通常设置有压降补偿电路(IRDrop补偿电路)，IRDrop补偿电路能够获取各个发光子像素的亮度数据，并进行相应的电压补偿。而在上述实施方式中，IRDrop补偿电路可以获取各个颜色的发光子像素的亮度数据，并统计不同颜色的发光子像素分别对应的发光数量。In an optional implementation manner, a voltage drop compensation circuit (IRDrop compensation circuit) is usually provided in the driver chip of the display panel, and the IRDrop compensation circuit can acquire brightness data of each light-emitting sub-pixel and perform corresponding voltage compensation. In the above implementation manner, the IRDrop compensation circuit can acquire the luminance data of the light-emitting sub-pixels of each color, and count the light-emitting quantities corresponding to the light-emitting sub-pixels of different colors.
需要说明的是，IRDrop补偿电路仅能够对不同颜色的发光子像素分别对应的发光数量进行计数统计，并发送至驱动芯片，驱动芯片在接收到各个颜色的发光子像素分别对应的发光数量后，可以根据各个颜色的发光子像素分别对应的发光数量以及总发光数量计算各个颜色的发光子像素的发光比例。It should be noted that the IRDrop compensation circuit can only count and count the light-emitting quantities corresponding to the light-emitting sub-pixels of different colors, and send them to the driver chip. After the driver chip receives the light-emitting quantities corresponding to the light-emitting sub-pixels of each color, The light-emitting ratio of the light-emitting sub-pixels of each color may be calculated according to the light-emitting quantities corresponding to the light-emitting sub-pixels of each color and the total light-emitting quantity.
在一种例举的实施方式中，显示面板内设置有多个IRDrop补偿电路，显示面板的显示区域包括多个子区域，每个IRDrop补偿电路能够对与其对应的子区域待显示的亮度数据进行处理，以得到该子区域内各个颜色的发光子像素的亮度数据，并根据发光阈值统计该子区域内各个颜色的发光子像素分别对应的发光数量。驱动芯片在获取每个IRDrop补偿电路统计的各个颜色的发光子像素分别对应的发光数量后，针对每种颜色的发光子像素，可以将多个IRDrop补偿电路统计的发光数量相加，得到显示面板整个显示区域中，每种颜色的发光子像素的发光数量。In an exemplary embodiment, a plurality of IRDrop compensation circuits are provided in the display panel, the display area of the display panel includes a plurality of sub-areas, and each IRDrop compensation circuit can process the luminance data to be displayed in the corresponding sub-area , so as to obtain the luminance data of the light-emitting sub-pixels of each color in the sub-region, and calculate the light-emitting quantities corresponding to the light-emitting sub-pixels of each color in the sub-region according to the light-emitting threshold. After the driver chip obtains the luminescence quantities corresponding to the light-emitting sub-pixels of each color counted by each IRDrop compensation circuit, it can add the light-emitting quantities counted by multiple IRDrop compensation circuits for the light-emitting sub-pixels of each color to obtain a display panel In the entire display area, the number of light-emitting sub-pixels of each color.
在S330中，在确定单个图像画面中各个颜色的发光子像素分别对应的发光数量后，可以根据发光数量确定各个颜色的发光子像素的发光比例。In S330, after determining the luminous quantities corresponding to the luminous sub-pixels of each color in a single image frame, the luminous ratios of the luminous sub-pixels of each color may be determined according to the luminous quantities.
各个颜色的发光子像素的发光比例可以根据每种颜色的发光子像素的发光数量与所有发光子像素的发光数量计算得到。例如，若单个图像画面中红绿蓝三种颜色的发光子像素分别对应的发光数量为1000、0、0，则红绿蓝三种颜色的发光子像素的发光比例分别为100％、0％、0％。若单个图像画面中红绿蓝三种颜色的发光子像素分别对应的发光数量为1000、0、500，则红绿蓝三种颜色的发光子像素的发光比例分别为66.7％、0％、33.3％。The light-emitting ratio of the light-emitting sub-pixels of each color can be calculated according to the light-emitting quantity of the light-emitting sub-pixels of each color and the light-emitting quantity of all light-emitting sub-pixels. For example, if the light-emitting sub-pixels of red, green and blue colors correspond to 1000, 0, and 0 respectively in a single image frame, then the light-emitting ratios of red, green and blue light-emitting sub-pixels are 100% and 0% respectively. , 0%. If the light-emitting sub-pixels of red, green and blue colors correspond to 1000, 0, and 500 light-emitting sub-pixels in a single image frame, the light-emitting ratios of red, green, and blue light-emitting sub-pixels are 66.7%, 0%, and 33.3% respectively. %.

上述S320，可以包括：The above S320 may include:
S430，在单个图像画面中，根据每个发光单元中各个颜色的发光子像素的亮度数据，对不同颜色的发光子像素的发光数量进行累加统计，得到单个图像画面中每种颜色的发光子像素的发光数量。S430. In a single image frame, according to the luminance data of the light-emitting sub-pixels of each color in each light-emitting unit, perform cumulative statistics on the light-emitting quantities of the light-emitting sub-pixels of different colors, to obtain the light-emitting sub-pixels of each color in the single image frame amount of luminescence.
在本实施例中，显示面板可以根据图像数据，以发光单元为单位获取各个发光单元的显示数据。每个发光单元的显示数据包括发光单元中各个颜色的发光子像素的亮度数据。通过对每个发光单元中不同颜色的发光子像素的亮度数据进行累加统计，可以得到每种颜色的发光子像素的发光数量。In this embodiment, the display panel can acquire the display data of each light emitting unit in units of light emitting units according to the image data. The display data of each light-emitting unit includes brightness data of light-emitting sub-pixels of each color in the light-emitting unit. By accumulating and counting the luminance data of the light-emitting sub-pixels of different colors in each light-emitting unit, the light-emitting quantity of the light-emitting sub-pixels of each color can be obtained.
在S410中，单个图像画面的图像数据可以是由各个发光单元的显示数据构成。In S410, the image data of a single image frame may be composed of display data of each light emitting unit.
显示面板中可以包括多个发光单元，每个发光单元中包括显示面板每种颜色的发光子像素。在显示面板包括红绿蓝三种颜色的发光子像素时，每个发光单元包括该三种不同颜色的发光子像素，且各种颜色的发光子像素为至少一个。在显示面板包括红绿蓝白或红绿蓝黄四种颜色的发光子像素时，每个发光单元包括该四种不同颜色的发光子像素，且各种颜色的发光子像素为至少一个。除此之外，发光单元中相同颜色的发光子像素还可以设置为两个及以上。例如，发光单元中也可以包括RGBG发光子像素，即红蓝两色的发光子像素各一个，绿色发光子像素两个。发光单元可为像素重复单元。The display panel may include a plurality of light emitting units, and each light emitting unit includes light emitting sub-pixels of each color of the display panel. When the display panel includes light-emitting sub-pixels of three colors of red, green and blue, each light-emitting unit includes light-emitting sub-pixels of three different colors, and there is at least one light-emitting sub-pixel of each color. When the display panel includes light-emitting sub-pixels of four colors of red, green, blue, white or red, green, blue and yellow, each light-emitting unit includes light-emitting sub-pixels of the four different colors, and there is at least one light-emitting sub-pixel of each color. In addition, there may be two or more light emitting sub-pixels of the same color in the light emitting unit. For example, the light-emitting unit may also include RGBG light-emitting sub-pixels, that is, one red and blue light-emitting sub-pixels, and two green light-emitting sub-pixels. The light emitting unit may be a pixel repeating unit.
在S420中，在根据图像画面的图像数据确定某个发光单元的显示数据后，可以根据该显示数据中不同位置的数据确定各个颜色的发光子像素的亮度数据。例如，发光单元的显示数据可以为单个数据帧，各个颜色的发光子像素对应的亮度数据分别位于单个数据帧的不同位置，通过读取数据帧即可得到各个颜色的发光子像素对应的亮度数据。In S420, after the display data of a certain light-emitting unit is determined according to the image data of the image frame, the brightness data of the light-emitting sub-pixels of each color may be determined according to data at different positions in the display data. For example, the display data of the light-emitting unit can be a single data frame, and the brightness data corresponding to the light-emitting sub-pixels of each color are located in different positions of the single data frame, and the brightness data corresponding to the light-emitting sub-pixels of each color can be obtained by reading the data frame .
在S430中，根据单个图像画面的图像数据，可以确定各个发光单元中每种颜色的发光子像素的亮度数据，并根据亮度数据对每种颜色的发光子像素的总发光数量进行累加统计。总发光数量为该图像画面中对应颜色的发光子像素的发光数量。In S430, according to the image data of a single image frame, the luminance data of the luminous sub-pixels of each color in each luminous unit can be determined, and the total luminous quantity of the luminous sub-pixels of each color can be accumulated and counted according to the luminance data. The total light emitting quantity is the light emitting quantity of the light emitting sub-pixels of the corresponding color in the image frame.
以某个发光单元为例，该发光单元对应的红绿蓝三种颜色的亮度数据中，红色发光子像素的亮度数据大于发光阈值，蓝色发光子像素和绿色发光子像素的亮度数据小于发光阈值。即，该发光单元中红色发光子像素的发光数量为1，蓝色发光子像素和绿色发光子像素的发光数量为0。在对该发光单元进行累加统计前，红绿蓝三种颜色的发光子像素的总发光数量分别为1000、0、0，则根据该发光单元中每种颜色的发光子像素的亮度数据进行累加统计后，红绿蓝三种颜色的发光子像素的总发光数量分别为1001、0、0。Taking a light-emitting unit as an example, among the luminance data of the three colors of red, green and blue corresponding to the light-emitting unit, the luminance data of the red light-emitting sub-pixel is greater than the light-emitting threshold, and the luminance data of the blue light-emitting sub-pixel and the green light-emitting sub-pixel are lower than the light-emitting threshold. threshold. That is, the light emitting quantity of the red light emitting sub-pixel in the light emitting unit is 1, and the light emitting quantity of the blue light emitting sub-pixel and the green light emitting sub-pixel is 0. Before accumulating statistics on the light-emitting unit, the total number of light-emitting sub-pixels of the three colors of red, green and blue are 1000, 0, and 0, respectively, and then accumulate according to the brightness data of the light-emitting sub-pixels of each color in the light-emitting unit After statistics, the total light-emitting numbers of the light-emitting sub-pixels of the three colors of red, green and blue are 1001, 0, and 0, respectively.
在S220中，在确定待显示的图像画面中各个颜色的发光子像素的发光比例后，可以根据该发光比例确定该图像画面的颜色类型。In S220, after determining the light-emitting ratio of the light-emitting sub-pixels of each color in the image frame to be displayed, the color type of the image frame may be determined according to the light-emitting ratio.
上述图像画面的颜色类型，可以是纯色图像画面，例如纯红色图像画面、纯蓝色图像画面、纯绿色图像画面等，也可以是两色混合的图像画面，例如红蓝混合绿色缺失的图像画面、红绿混合蓝色缺失的图像画面、蓝绿混合红色缺失的图像画面等，还可以是多种颜色混合的图像画面，在此不做限制。The color type of the image picture above can be a solid color picture picture, such as a pure red picture picture, a pure blue picture picture, a pure green picture picture, etc., or a two-color mixed picture picture, such as a red and blue picture picture with green missing , an image frame in which red and green are mixed and blue is missing, an image frame in which blue and green are mixed and red is missing, etc., may also be an image frame in which multiple colors are mixed, which is not limited here.
根据发光比例确定图像画面的颜色类型的方式可以是，根据各个颜色的发光子像素的发光比例，判断是否存在一种颜色的发光子像素的发光比例高于着色比例阈值。例如，在绿色发光子像素的发光比例高于着色比例阈值时，可以确定该图像画面的颜色种类至少包括绿色。通过对各色发光子像素进行比较，可以确定图像画面所包括的颜色种类，以确定图像画面的颜色类型。例如，图像画面中红绿蓝三种颜色的发光子像素的发光比例分别为100％、0％、0％时，可以确定图像画面包括的颜色种类为红色，图像画面的颜色类型为纯红色图像画面；在红绿蓝三种颜色的发光子像素的发光比例分别为50％、50％、0％时，可以确定图像画面包括的颜色种类为红色和蓝色，图像画面的颜色类型为红蓝混合绿色缺失的图像画面。The method of determining the color type of the image frame according to the light-emitting ratio may be to determine whether the light-emitting sub-pixel of one color has a light-emitting ratio higher than the coloring ratio threshold according to the light-emitting ratio of the light-emitting sub-pixels of each color. For example, when the light emitting ratio of the green light emitting sub-pixel is higher than the coloring ratio threshold, it may be determined that the color category of the image frame includes at least green. By comparing the light-emitting sub-pixels of different colors, the color type included in the image frame can be determined, so as to determine the color type of the image frame. For example, when the light-emitting ratios of the red, green and blue light-emitting sub-pixels in the image frame are 100%, 0%, and 0% respectively, it can be determined that the color type included in the image frame is red, and the color type of the image frame is a pure red image Picture; when the light-emitting ratios of the light-emitting sub-pixels of red, green and blue are 50%, 50%, and 0% respectively, it can be determined that the color types included in the image picture are red and blue, and the color type of the picture picture is red and blue Blended image frames with missing green.
在另一种实施方式中，根据各个颜色的发光子像素的发光比例确定图像画面的颜色类型的方式还可以是，根据各个颜色的发光子像素的发光比例，判断是否存在一种颜色的发光子像素的发光比例低于缺色比例阈值。例如，在绿色发光子像素的发光比例低于缺色比例阈值时，可以确定该图像画面缺失绿色。通过对各色发光子像素进行比较，可以确定图像画面所缺失的颜色。例如，在图像画面包括红色、绿色和蓝色的发光子像素，并且图像画面缺失绿色时，可以确定图像画面的颜色类型为红蓝混合绿色缺失的图像画面；在图像画面缺失蓝色和绿色时，可以确定图像画面的颜色类型为纯红色图像画面。例如，在红绿蓝三种颜色的发光子像素的发光比例分别为100％、0％、0％时，该图像画面为缺失绿色以及蓝色的图像画面。In another embodiment, the method of determining the color type of the image frame according to the light-emitting ratio of the light-emitting sub-pixels of each color may also be to determine whether there is a light-emitting sub-pixel of one color according to the light-emitting ratio of the light-emitting sub-pixels of each color. The pixel's light ratio is below the color loss ratio threshold. For example, when the luminous ratio of the green luminous sub-pixel is lower than the color deficiency ratio threshold, it may be determined that the image frame lacks green. By comparing the light-emitting sub-pixels of various colors, the missing color of the image frame can be determined. For example, when the image frame includes red, green and blue light-emitting sub-pixels, and the image frame lacks green, it can be determined that the color type of the image frame is an image frame in which red, blue, and green are missing; when the image frame lacks blue and green , it can be determined that the color type of the image frame is a pure red image frame. For example, when the light-emitting ratios of red, green and blue light-emitting sub-pixels are 100%, 0%, and 0% respectively, the image frame is an image frame lacking green and blue.
作为一种可选的实施例，显示面板的发光子像素可以包括红色发光子像素、绿色发光子像素、蓝色发光子像素。As an optional embodiment, the light-emitting sub-pixels of the display panel may include red light-emitting sub-pixels, green light-emitting sub-pixels, and blue light-emitting sub-pixels.
图像画面为纯红色图像画面、或纯蓝色图像画面、或红蓝混合绿色缺失的图像画面时对应的默认驱动电压小于图像画面包括绿色时对应的默认驱动电压。即，图像画面为纯绿色图像画面或者包含绿色的混合图像画面时，提供给显示面板的驱动芯片的默认驱动电压较高。而在图像画面为纯红色图像画面、或纯蓝色图像画面、或红蓝混合绿色缺失的图像画面时，提供给显示面板的驱动芯片的默认驱动电压较低。因此，在待显示的图像画面的颜色类型由包含绿色的图像画面变为不包含绿色的图像画面时，可以相应地降低提供给驱动芯片的默认驱动电压，以减小维持默认驱动电压所产生的功率损耗。The corresponding default driving voltage when the image frame is a pure red image frame, or pure blue image frame, or an image frame in which red, blue and green are missing is smaller than that corresponding to when the image frame includes green. That is, when the image frame is a pure green image frame or a mixed image frame containing green, the default driving voltage provided to the driver chip of the display panel is relatively high. When the image frame is a pure red image frame, or a pure blue image frame, or an image frame in which red, blue, and green are absent, the default driving voltage provided to the driver chip of the display panel is relatively low. Therefore, when the color type of the image frame to be displayed changes from an image frame containing green to an image frame not containing green, the default driving voltage provided to the driver chip can be correspondingly reduced to reduce the cost of maintaining the default driving voltage. Power loss.
作为一种可选的实施例，上述S220，可以包括：As an optional embodiment, the above S220 may include:
S510，根据发光比例确定图像画面是否为第一图像画面；第一图像画面为缺失至少一种颜色的图像画面；S510. Determine whether the image frame is a first image frame according to the lighting ratio; the first image frame is an image frame lacking at least one color;
在本实施例中，在确定待显示的图像画面中各个颜色的发光子像素的发光比例后，可以根据该发光比例确定该图像画面是否为第一图像画面。其中，第一图像画面可以为缺失至少一种颜色的图像画面。例如，以显示面板包括红绿蓝三种发光子像素为例，第一图像画面可以是缺失绿色的图像画面，也可以是缺失蓝色的图像画面，还可以是缺失红色的图像画面。In this embodiment, after determining the light-emitting ratio of the light-emitting sub-pixels of each color in the image frame to be displayed, whether the image frame is the first image frame can be determined according to the light-emitting ratio. Wherein, the first image frame may be an image frame lacking at least one color. For example, taking a display panel including red, green and blue light-emitting sub-pixels as an example, the first image frame may be an image frame lacking green, may be an image frame lacking blue, or may be an image frame lacking red.
需要说明的是，第一图像画面可以为单色图像画面，也可以是除缺失颜色以外的其他多个颜色混合形成的图像画面，例如，在第一图像画面缺失绿色的图像画面时，该第一图像画面可以是纯红色图像画面、纯蓝色图像画面或者由红色和蓝色混合形成的图像画面。It should be noted that the first image frame may be a monochrome image frame, or may be an image frame formed by mixing multiple colors other than the missing color. For example, when the first image frame lacks a green image frame, the first image frame An image frame may be a pure red image frame, a pure blue image frame or an image frame formed by mixing red and blue.
根据发光比例确定图像画面是否为第一图像画面的方式可以是，根据各个颜色的发光子像素的发光比例，判断是否存在一种颜色的发光子像素的发光比例低于比例阈值。例如在绿色发光子像素的发光比例低于比例阈值1％时，可以确定该图像画面为缺失绿色的第一图像画面。例如，在红绿蓝三种颜色的发光子像素的发光比例分别为100％、0％、0％时，该图像画面为缺失绿色以及蓝色的第一图像画面，也即纯红色图像画面。The manner of determining whether the image frame is the first image frame according to the light emission ratio may be to determine whether the light emission ratio of the light emission sub-pixels of one color is lower than the ratio threshold according to the light emission ratio of the light emission sub-pixels of each color. For example, when the light emitting ratio of the green light emitting sub-pixel is lower than the ratio threshold 1%, it may be determined that the image frame is the first image frame lacking green. For example, when the light-emitting ratios of red, green and blue light-emitting sub-pixels are 100%, 0%, and 0% respectively, the image frame is the first image frame lacking green and blue, that is, a pure red image frame.
作为一种可选的实施例，上述S120，可以包括：As an optional embodiment, the above S120 may include:
S520，在单个图像画面为第一图像画面的情况下，根据第一图像画面的缺失颜色和/或待显示颜色，调整显示面板的默认驱动电压，第一图像画面为缺失至少一种颜色的图像画面。S520, when the single image frame is the first image frame, adjust the default driving voltage of the display panel according to the missing color and/or the color to be displayed of the first image frame, where the first image frame is an image missing at least one color screen.
在本实施例中，显示面板可以根据第一图像画面缺失的颜色和/或待显示的颜色调整发光子像素的默认驱动电压。以显示面板包括红、绿、蓝三种发光子像素为例，为了使得三种颜色的发光子像素均能够正常发光，默认驱动电压需要设置为满足三种颜色的发光子像素正常发光所需的最低驱动电压。而在第一图像画面缺失至少一种颜色时，默认驱动电压可以设置为满足剩余两种颜色或剩余一种颜色的发光子像素正常发光所需的最低驱动电压。即第一图像画面缺失某种颜色时，默认驱动电压可以进行相应降低，以在进行发光的发光子像素仍能够正常发光，显示效果满足要求的前提下，通过降低驱动电压实现显示功耗的减小。In this embodiment, the display panel can adjust the default driving voltage of the light-emitting sub-pixels according to the missing color of the first image frame and/or the color to be displayed. Take the display panel including red, green, and blue light-emitting sub-pixels as an example. In order to enable the light-emitting sub-pixels of the three colors to emit light normally, the default driving voltage needs to be set to meet the requirements for the light-emitting sub-pixels of the three colors to emit light normally. Minimum drive voltage. When the first image frame lacks at least one color, the default driving voltage can be set as the lowest driving voltage required by the remaining two colors or the remaining one color of the light-emitting sub-pixels to normally emit light. That is, when a certain color is missing in the first image, the default driving voltage can be reduced accordingly, so that the display power consumption can be reduced by reducing the driving voltage under the premise that the light-emitting sub-pixels that emit light can still emit light normally and the display effect meets the requirements. Small.
在S520中，在确定待显示的单个图像画面为第一图像画面时，显示面板可以根据该第一图像画面中所缺失的颜色和/或待显示的颜色对发光子像素的默认驱动电压进行调整，以使得调整后的驱动电压能够满足第一图像画面中待显示颜色的发光子像素的驱动电压需求。In S520, when determining that the single image frame to be displayed is the first image frame, the display panel may adjust the default driving voltage of the light-emitting sub-pixel according to the missing color in the first image frame and/or the color to be displayed , so that the adjusted driving voltage can meet the driving voltage requirements of the light-emitting sub-pixels of the color to be displayed in the first image frame.
以显示面板中包括红绿蓝三种颜色的发光子像素为例，显示面板的电源能够为驱动芯片提供默认驱动电压AVDD，驱动芯片可以根据该默认驱动电压生成显示驱动过程中所需的其他电压。例如驱动芯片利用默认驱动电压生成的电压可以包括但不限于扫描信号的高电平有效信号VGH、数据信号的两个参考电平VGSP(下限电压值)、VGMP(上限电压值)、初始化电压Vref、数字电压信号OVDD等电压信号的其中一种或多种。Taking the light-emitting sub-pixels of red, green and blue in the display panel as an example, the power supply of the display panel can provide the default driving voltage AVDD for the driver chip, and the driver chip can generate other voltages required in the display driving process according to the default driving voltage. . For example, the voltage generated by the driver chip using the default driving voltage may include but not limited to the high-level active signal VGH of the scan signal, two reference levels VGSP (lower limit voltage value) of the data signal, VGMP (upper limit voltage value), initialization voltage Vref One or more of voltage signals such as digital voltage signal OVDD and the like.
以显示面板包括红色、绿色以及蓝色三种颜色的发光子像素为例。通常情况下，不同出光颜色的发光子像素在正常发光亮度区间内进行发光所需的相关电压信号可能相同，也可能不同。Take the display panel as an example including three light-emitting sub-pixels of red, green and blue. Generally, the related voltage signals required for the light-emitting sub-pixels of different light-emitting colors to emit light in the normal light-emitting brightness range may be the same or different.
不同出光颜色的发光子像素所接收的相同电压信号可以是扫描信号的高电平信号。例如，不同出光颜色的发光子像素的像素电路中均包括数据写入晶体管，而驱动芯片为不同颜色发光子像素的数据写入晶体管所提供的扫描信号的高电平信号通常是一致的。The same voltage signal received by the light-emitting sub-pixels of different light-emitting colors may be a high-level signal of the scanning signal. For example, the pixel circuits of the light-emitting sub-pixels of different light-emitting colors all include data write-in transistors, and the high-level signals of the scanning signals provided by the driving chip to the data-write transistors of different light-emitting sub-pixels are generally consistent.
不同出光颜色的发光子像素所接收的不同电压信号可以是发光元件阳极的初始化信号Vref或者数据信号的两个参考电平VGSP、VGMP。例如，不同颜色的发光子像素的发光元件阳极进行初始化所需的电压大小可能并不相同；不同颜色的发光子像素对应的数据信号的电压区间也可能存在差异，从而导致不同颜色的发光子像素对应的参考电平VGSP、VGMP并不完全一致。The different voltage signals received by the light-emitting sub-pixels of different light-emitting colors may be the initialization signal Vref of the anode of the light-emitting element or two reference levels VGSP and VGMP of the data signal. For example, the voltages required for initialization of the anodes of light-emitting sub-pixels of different colors may be different; the voltage intervals of data signals corresponding to light-emitting sub-pixels of different colors may also be different, resulting in the The corresponding reference levels VGSP and VGMP are not completely consistent.
由于驱动芯片在根据默认驱动电压生成初始化信号、数据信号的参考电平以及其他显示驱动过程中所需的相关电压时，需要考虑到各个颜色的发光子像素的正常发光需求。因此，默认驱动电压的最小值应当至少能够满足每种颜色的发光子像素的数据信号电压区间的需求以及初始化信号的电压需求。即，在不同颜色的发光子像素分别对应不同的数据信号参考电平VGSP和VGMP时，默认驱动电压的最小值受到最大的VGMP的影响。例如，在绿色发光子像素对应的数据信号参考电平VGMPg大于红色发光子像素对应的数据信号参考电平VGMPr以及蓝色发光子像素对应的数据信号参考电平VGMPb时，默认驱动电压的最小值取决于绿色VGMPg。同样地，在不同颜色的发光子像素的发光元件阳极所需的初始化信号的电压大小不一致时，默认驱动电压的最小值也取决于多个初始化信号中的最大电压。When the driver chip generates the initialization signal, the reference level of the data signal, and other related voltages required in the display driving process according to the default driving voltage, it needs to consider the normal lighting requirements of the light-emitting sub-pixels of each color. Therefore, the minimum value of the default driving voltage should at least be able to meet the requirements of the voltage range of the data signal and the voltage of the initialization signal of the light-emitting sub-pixels of each color. That is, when the light-emitting sub-pixels of different colors correspond to different data signal reference levels VGSP and VGMP, the minimum value of the default driving voltage is affected by the maximum VGMP. For example, when the data signal reference level VGMPg corresponding to the green light-emitting sub-pixel is greater than the data signal reference level VGMPr corresponding to the red light-emitting sub-pixel and the data signal reference level VGMPb corresponding to the blue light-emitting sub-pixel, the minimum value of the default driving voltage Depends on green VGMPg. Similarly, when the voltages of the initialization signals required by the anodes of the light-emitting elements of the light-emitting sub-pixels of different colors are inconsistent, the minimum value of the default driving voltage also depends on the maximum voltage among the multiple initialization signals.
由上述分析可知，在待显示的图像画面中，每种颜色的发光子像素均进行发光时，默认驱动电压需要满足所有颜色的发光子像素的正常发光需求。而在待显示的图像画面存在缺失颜色，或者图像画面中待显示的颜色并非所有颜色时，默认驱动电压仅需要满足部分颜色的发光子像素的正常发光需求。因此，在显示面板显示第一图像画面时，所需的默认驱动电压相较于正常图像画面(不缺失颜色的图像画面)的默认驱动电压较低。From the above analysis, it can be seen that in the image frame to be displayed, when the light-emitting sub-pixels of each color emit light, the default driving voltage needs to meet the normal light-emitting requirements of the light-emitting sub-pixels of all colors. However, when there are missing colors in the image frame to be displayed, or the colors to be displayed in the image frame are not all colors, the default driving voltage only needs to meet the normal light emission requirements of light-emitting sub-pixels of some colors. Therefore, when the display panel displays the first image frame, the required default driving voltage is lower than that of the normal image frame (image frame without missing color).
以显示面板包括红绿蓝三种颜色的发光子像素为例，在显示面板显示的图像画面为第一图像画面时，由于第一图像画面为缺失至少一种颜色的图像画面，显示面板在显示该第一图像画面时，默认驱动电压仅需要满足其中两种颜色的发光子像素的正常发光需求或者其中一种颜色的发光子像素的正常发光需求。根据第一图像画面中的缺失颜色和/或待显示颜色，可以确定默认驱动电压在满足该部分颜色的发光子像素的正常发光需求时，相较于正常图像画面下默认驱动电压的电压降幅。Taking the display panel including red, green and blue light-emitting sub-pixels as an example, when the image frame displayed on the display panel is the first image frame, since the first image frame is an image frame lacking at least one color, the display panel displays In the first image frame, the default driving voltage only needs to meet the normal light emission requirements of the light-emitting sub-pixels of two colors or the normal light-emitting requirements of the light-emitting sub-pixels of one color. According to the missing color and/or the color to be displayed in the first image frame, when the default driving voltage satisfies the normal lighting requirements of the light-emitting sub-pixels of this part of the color, the voltage drop compared with the default driving voltage in the normal image frame can be determined.
根据第一图像画面中缺失的颜色，可以对应降低提供给显示面板的驱动芯片的默认驱动电压，并且不会影响到第一图像画面中各个发光子像素的发光亮度。由于显示面板在第一图像画面下提供的默认驱动电压低于正常图像画面(不缺失颜色的图像画面)下提供的默认驱动电压，但显示效果不受影响，在显示第一图像画面时，能够通过降低默认驱动电压实现显示功耗的降低。但默认驱动电压不能持续调低，否则不能满足显示效果要求，或，导致触发供电电源内部的其他补偿功能，导致功耗增加。According to the missing color in the first image frame, the default driving voltage provided to the driving chip of the display panel can be correspondingly reduced without affecting the luminance of each light-emitting sub-pixel in the first image frame. Because the default driving voltage provided by the display panel under the first image frame is lower than the default driving voltage provided under the normal image frame (image frame without missing color), but the display effect is not affected, when the first image frame is displayed, it can be Display power reduction is achieved by lowering the default drive voltage. However, the default driving voltage cannot be continuously lowered, otherwise the display effect requirements cannot be met, or other compensation functions inside the power supply will be triggered, resulting in increased power consumption.
请参照图5至图7，作为一种可选的实施例，上述S520，可以包括：Please refer to FIG. 5 to FIG. 7, as an optional embodiment, the above S520 may include:
S610，根据第一图像画面的缺失颜色以及第一对应关系，确定与第一图像画面对应的显示面板的第一驱动电压；第一对应关系为缺失颜色与驱动电压的对应关系；S610, according to the missing color of the first image frame and the first corresponding relationship, determine the first driving voltage of the display panel corresponding to the first image frame; the first corresponding relationship is the corresponding relationship between the missing color and the driving voltage;
或，S620，根据第一图像画面的待显示颜色以及第二对应关系，确定与第一图像画面对应的显示面板的第一驱动电压，第二对应关系为待显示颜色与驱动电压的对应关系；Or, S620, determine the first driving voltage of the display panel corresponding to the first image frame according to the color to be displayed of the first image frame and the second corresponding relationship, the second corresponding relationship is the corresponding relationship between the color to be displayed and the driving voltage;
S630，将显示面板的默认驱动电压调整为第一驱动电压。S630. Adjust the default driving voltage of the display panel to the first driving voltage.
在本实施例中，显示面板可以根据第一图像画面中的缺失颜色，确定该第一图像画面对应的第一驱动电压，并将默认驱动电压调整为第一驱动电压。显示面板也可以根据第一图像画面的待显示颜色，确定该第一图像画面对应的第一驱动电压。驱动芯片在第一驱动电压下，能够满足未缺失颜色的发光子像素的正常发光需求，不会影响到未缺失颜色的发光子像素的发光亮度。将默认驱动电压调整为第一驱动电压后，不会影响到第一图像画面的显示效果，并且能够通过降低驱动电压的电压幅值实现显示功耗的降低。In this embodiment, the display panel may determine the first driving voltage corresponding to the first image frame according to the missing color in the first image frame, and adjust the default driving voltage to the first driving voltage. The display panel may also determine the first driving voltage corresponding to the first image frame according to the color to be displayed of the first image frame. Under the first driving voltage, the driving chip can meet the normal lighting requirements of the light-emitting sub-pixels with no missing color, and will not affect the light-emitting brightness of the light-emitting sub-pixels with no missing color. After the default driving voltage is adjusted to the first driving voltage, the display effect of the first image frame will not be affected, and the display power consumption can be reduced by reducing the voltage amplitude of the driving voltage.
在S610中，确定第一驱动电压时，可以是根据第一图像画面的缺失颜色来确定第一驱动电压。In S610, when determining the first driving voltage, the first driving voltage may be determined according to the missing color of the first image frame.
根据第一图像画面的缺失颜色来确定第一驱动电压的方式可以是，在确定第一图像画面中的缺失颜色后，可以根据该缺失颜色以及第一对应关系确定对应的第一驱动电压。该第一对应关系为缺失颜色与驱动电压的对应关系。例如，在缺失颜色为绿色时，对应的第一驱动电压为Vg；在缺失颜色为红色时，对应的第一驱动电压为Vr；在缺失颜色为蓝色时，对应的第一驱动电压为Vb。The manner of determining the first driving voltage according to the missing color of the first image frame may be that after determining the missing color in the first image frame, the corresponding first driving voltage may be determined according to the missing color and the first corresponding relationship. The first correspondence is the correspondence between missing colors and driving voltages. For example, when the missing color is green, the corresponding first driving voltage is Vg; when the missing color is red, the corresponding first driving voltage is Vr; when the missing color is blue, the corresponding first driving voltage is Vb .
以红绿蓝三种颜色的发光元件为例，在第一图像画面为缺失绿色的图像画面时，该图像画面可以仅由红色发光子像素和蓝色发光子像素进行发光显示。在显示面板所提供的默认驱动电压能够满足红色发光子像素和蓝色发光子像素的正常发光需求时，即可保障红蓝发光子像素正常发光，以正常显示第一图像画面。即，在第一图像画面为缺失绿色时，所提供的第一驱动电压可以满足以下公式：Taking the light-emitting elements of red, green and blue as an example, when the first image frame is an image frame lacking green, the image frame can be displayed by only red light-emitting sub-pixels and blue light-emitting sub-pixels. When the default driving voltage provided by the display panel can meet the normal lighting requirements of the red light emitting sub-pixel and the blue light emitting sub-pixel, normal light emission of the red and blue light emitting sub-pixels can be ensured to normally display the first image frame. That is, when the first image frame is missing green, the provided first driving voltage may satisfy the following formula:
Vg≥max{V1、V3}；Vg≥max{V1, V3};
其中，Vg为第一图像画面缺失绿色时提供给显示面板的第一驱动电压，V1为显示面板正常显示纯红色图像画面时，驱动芯片所需的最低驱动电压，V3为显示面板正常显示纯蓝色图像画面时，驱动芯片所需的最低驱动电压。Among them, Vg is the first driving voltage provided to the display panel when the first image is missing green, V1 is the minimum driving voltage required by the driver chip when the display panel normally displays a pure red image, and V3 is the display panel normally displays pure blue The minimum driving voltage required to drive the chip when the color image is displayed.
同样地，在第一图像画面缺失红色时，显示面板可以确定第一驱动电压Vr为：Similarly, when the first image frame lacks red, the display panel can determine that the first driving voltage Vr is:
Vr≥max{V2、V3}；Vr≥max{V2, V3};
其中，V2为显示面板正常显示纯绿色图像画面时，驱动芯片所需的最低驱动电压。Wherein, V2 is the minimum driving voltage required by the driving chip when the display panel normally displays a pure green image.
在第一图像画面缺失蓝色时，显示面板可以确定第一驱动电压Vb为：When the first image frame lacks blue, the display panel can determine that the first driving voltage Vb is:
Vb≥max{V1、V2}。Vb≥max{V1, V2}.
由于不同颜色的发光子像素在正常发光时所需的最低驱动电压可能相同，也可能不相同。因此，在默认驱动电压的实际降压过程中，可能存在默认驱动电压不发生变化的情形。例如，在V1、V2、V3互不相同时，为了实现正常图像画面(未缺失颜色的图像画面)的发光亮度需求，默认驱动电压Vd应当不小于V1、V2、V3中的最大值。假设V1、V2、V3的大小关系为V2>V1>V3，则正常图像画面下，默认驱动电压的电压范围内的最小值为V2。The minimum driving voltages required by light-emitting sub-pixels of different colors may be the same or different when they normally emit light. Therefore, during the actual step-down process of the default driving voltage, there may be a situation that the default driving voltage does not change. For example, when V1, V2, and V3 are different from each other, in order to realize the luminance requirement of normal image frames (image frames without missing colors), the default driving voltage Vd should not be less than the maximum value among V1, V2, and V3. Assuming that the magnitude relationship of V1, V2, and V3 is V2>V1>V3, then under normal image frames, the minimum value within the voltage range of the default driving voltage is V2.
根据上述第一驱动电压的确定方式可知，在第一图像画面缺失红色时，第一驱动电压Vr的最小值为V2；在第一图像画面缺失蓝色时，第一驱动电压Vb的最小值也为V2。也就是说，在第一图像画面包含绿色时，默认驱动电压Vd无法进行降压。即，绿色发光子像素正常发光所需的最低驱动电压V2为V1、V2和V3中的最大值时，第一驱动电压Vg的最小值为V1，可以通过将默认驱动电压AVDD降低为第一驱动电压Vg，在不影响红蓝发光子像素的正常发光的前提下，通过降低驱动电压实现显示功耗的减小。示例性的，图像画面由纯绿色图像画面或包括绿色的图像画面切换为纯红色图像画面、或纯蓝色图像画面、或红蓝混合绿色缺失的图像画面时，默认驱动电压AVDD将降低，由V2降低至V1或V3，从而能够通过降低默认驱动电压实现显示功耗的减小。但在第一图像画面缺失颜色为红色或蓝色时，默认驱动电压AVDD无法进行降低，则此时无法通过降低默认驱动电压实现显示功耗的减小。According to the determination method of the above-mentioned first driving voltage, it can be seen that when the first image frame lacks red, the minimum value of the first driving voltage Vr is V2; when the first image frame lacks blue, the minimum value of the first driving voltage Vb is also for V2. That is to say, when the first image frame contains green, the default driving voltage Vd cannot be stepped down. That is, when the minimum driving voltage V2 required for normal light emission of the green light-emitting sub-pixel is the maximum value among V1, V2 and V3, the minimum value of the first driving voltage Vg is V1, which can be reduced to the first driving voltage by reducing the default driving voltage AVDD The voltage Vg, on the premise of not affecting the normal light emission of the red and blue light-emitting sub-pixels, reduces the display power consumption by reducing the driving voltage. Exemplarily, when the image frame is switched from a pure green image frame or an image frame including green to a pure red image frame, or a pure blue image frame, or an image frame in which red and blue are mixed and green is missing, the default driving voltage AVDD will be reduced, by V2 is reduced to V1 or V3, so that the display power consumption can be reduced by reducing the default driving voltage. However, when the missing color of the first image frame is red or blue, the default driving voltage AVDD cannot be lowered, and the display power consumption cannot be reduced by lowering the default driving voltage at this time.
在S620中，上述第一驱动电压也可以根据第一图像画面的待显示颜色来进行确定。例如，在显示面板的亮度测试过程中，可以分别在不同的待显示颜色下，调整默认驱动电压，并确定不影响第一图像画面的显示效果的情况下，不同的待显示颜色下分别对应的第一驱动电压。例如，在显示面板包括红色、绿色和蓝色发光子像素时，可以分别确定待显示颜色为纯红色、纯绿色、纯蓝色、红蓝混合、红绿混合、蓝绿混合时分别对应的默认驱动电压，并生成待显示颜色与默认驱动电压的第二对应关系。In S620, the above-mentioned first driving voltage may also be determined according to the color to be displayed of the first image frame. For example, in the brightness test process of the display panel, the default driving voltage can be adjusted under different colors to be displayed, and it is determined that the display effect of the first image screen is not affected, and the corresponding voltages under the different colors to be displayed are respectively first driving voltage. For example, when the display panel includes red, green, and blue light-emitting sub-pixels, the corresponding default sub-pixels can be respectively determined when the colors to be displayed are pure red, pure green, pure blue, red-blue mixed, red-green mixed, and blue-green mixed. driving voltage, and generate a second corresponding relationship between the color to be displayed and the default driving voltage.
在实际显示过程中，根据待显示的图像画面的图像数据确定待显示的图像画面为第一图像画面，并确定第一图像画面的待显示颜色后，可以根据第二对应关系读取该待显示颜色对应的驱动电压，并将该读取到的驱动电压作为第一驱动电压。In the actual display process, according to the image data of the image frame to be displayed, it is determined that the image frame to be displayed is the first image frame, and after the color to be displayed of the first image frame is determined, the image frame to be displayed can be read according to the second corresponding relationship. The driving voltage corresponding to the color is used as the first driving voltage.
在S630中，显示面板在确定第一图像画面对应的第一驱动电压后，可以在显示该图像画面时，将提供给显示面板的驱动芯片的默认驱动电压降低为第一驱动电压，以降低显示面板的显示功耗。In S630, after the display panel determines the first driving voltage corresponding to the first image frame, it may reduce the default driving voltage provided to the driving chip of the display panel to the first driving voltage when displaying the image frame, so as to reduce the display voltage. Display power consumption of the panel.
请参照图8和图10，作为一种可选的实施例，上述S610，可以包括：Please refer to Figure 8 and Figure 10, as an optional embodiment, the above S610 may include:
S710，在第一图像画面的缺失颜色包括至少两种的情况下，根据第一对应关系确定每种缺失颜色分别对应的第二驱动电压；S710, in the case that the missing colors of the first image frame include at least two types, determine the second driving voltages respectively corresponding to each missing color according to the first correspondence relationship;
S720，根据多个第二驱动电压的最小值确定第一驱动电压。S720. Determine the first driving voltage according to the minimum value of the multiple second driving voltages.
在本实施例中，在第一图像画面中包括至少两种缺失颜色时，可以根据第一对应关系确定每种缺失颜色分别对应的第二驱动电压，并从多个第二驱动电压中确定最小值作为第一驱动电压。可以理解的是，对于未缺失的颜色，任一个第二驱动电压均能够满足该未缺失颜色的正常发光需求。例如，第一图像画面缺失蓝色和绿色两种颜色时，可以根据第一对应关系确定缺失蓝色对应的第二驱动电压以及缺失绿色对应的第二驱动电压。由于缺失蓝色对应的第二驱动电压能够满足红色发光子像素的正常发光需求、缺失绿色对应的第二驱动电压也能够满足红色发光子像素的正常发光需求，为了降低显示面板的显示功耗，可以选择最小的第二驱动电压作为第一驱动电压。In this embodiment, when the first image frame includes at least two missing colors, the second driving voltage corresponding to each missing color can be determined according to the first correspondence, and the minimum driving voltage can be determined from the plurality of second driving voltages. value as the first driving voltage. It can be understood that, for a color that is not missing, any second driving voltage can meet the normal light emission requirements of the color that is not missing. For example, when two colors of blue and green are missing in the first image frame, the second driving voltage corresponding to the missing blue and the second driving voltage corresponding to the missing green may be determined according to the first correspondence relationship. Since the second driving voltage corresponding to the absence of blue can meet the normal light emission requirements of the red light-emitting sub-pixels, and the second driving voltage corresponding to the absence of green can also meet the normal light emission requirements of the red light-emitting sub-pixels, in order to reduce the display power consumption of the display panel, The smallest second driving voltage may be selected as the first driving voltage.
在S710中，在第一图像画面的缺失颜色包括两种颜色时，可以根据第一对应关系确定每种缺失颜色分别对应的第二驱动电压。以显示面板包括红绿蓝三种发光子像素为例，在第一图像画面缺失绿色和蓝色时，根据第一对应关系可以确定在缺失绿色时对应的第二驱动电压Vg以及在缺失蓝色时对应的第二驱动电压Vb。In S710, when the missing colors of the first image frame include two colors, the second driving voltage corresponding to each missing color may be determined according to the first correspondence relationship. Taking the display panel including red, green and blue light-emitting sub-pixels as an example, when green and blue are missing in the first image frame, the corresponding second driving voltage Vg when green is missing and the corresponding second driving voltage Vg when blue is missing can be determined according to the first correspondence relationship. When the corresponding second driving voltage Vb.
在S720中，在确定每种缺失颜色分别对应的第二驱动电压后，可以从多个第二驱动电压的最小值确定第一驱动电压。即，在显示缺失两种或两种以上的颜色时，可以确定各个缺失颜色分别对应的第二驱动电压，并将多个第二驱动电压的最小值作为第一驱动电压。In S720, after determining the second driving voltage corresponding to each missing color, the first driving voltage may be determined from the minimum value of the plurality of second driving voltages. That is, when displaying two or more missing colors, the second driving voltage corresponding to each missing color can be determined, and the minimum value of the multiple second driving voltages can be used as the first driving voltage.
在第一图像画面缺失绿色和蓝色，并确定缺失绿色时对应的第二驱动电压Vg以及缺失蓝色时对应的第二驱动电压Vb后，可以将第二驱动电压Vg以及第二驱动电压Vb中的较小值min{Vg、Vb}作为第一驱动电压。After the green and blue are missing in the first image frame, and the second driving voltage Vg corresponding to the missing green and the second driving voltage Vb corresponding to the missing blue are determined, the second driving voltage Vg and the second driving voltage Vb can be The smaller value min{Vg, Vb} in is used as the first driving voltage.
需要说明的是，在显示面板包括三种颜色的发光子像素时，若第一图像画面缺失两种颜色，则该第一图像画面为第三种颜色的纯色画面。而在显示面板包括四种或以上的颜色的发光子像素时，若第一图像画面缺失两种颜色，则该第一图像画面可能为纯色图像画面或者由至少两种颜色构成的图像画面。It should be noted that, when the display panel includes light-emitting sub-pixels of three colors, if the first image frame lacks two colors, the first image frame is a solid color frame of the third color. When the display panel includes light-emitting sub-pixels of four or more colors, if the first image frame lacks two colors, the first image frame may be a solid color image frame or an image frame composed of at least two colors.

在本实施例中，在第一图像画面中的待显示颜色包括至少两种的情况下可以根据第二对应关系确定每种待显示颜色分别对应的第三驱动电压，并从多个第三驱动电压中确定最大值作为第一驱动电压。可以理解的是，对于某种待显示颜色，只要驱动电压达到该待显示颜色对应的第三驱动电压，即可保障该待显示颜色的正常显示。而待显示颜色包括多种时，驱动电压应当满足每种待显示颜色对应的第三驱动电压，即，为了降低显示面板的显示功耗，第一驱动电压的最小电压值应当为多个第三驱动电压的最大值。In this embodiment, when there are at least two colors to be displayed in the first image frame, the third driving voltages corresponding to each color to be displayed can be determined according to the second correspondence, and the third driving voltages corresponding to each color to be displayed can be determined from a plurality of third driving voltages. The maximum value among the voltages is determined as the first driving voltage. It can be understood that, for a certain color to be displayed, as long as the driving voltage reaches the third driving voltage corresponding to the color to be displayed, the normal display of the color to be displayed can be guaranteed. When there are multiple colors to be displayed, the driving voltage should satisfy the third driving voltage corresponding to each color to be displayed, that is, in order to reduce the display power consumption of the display panel, the minimum voltage value of the first driving voltage should be a plurality of third driving voltages. The maximum value of the drive voltage.
在S730中，在第一图像画面的待显示颜色包括两种颜色时，可以根据第二对应关系确定每种待显示颜色分别对应的第三驱动电压。以显示面板包括红绿蓝三种发光子像素为例，在第一图像画面包括绿色和蓝色时，根据第二对应关系可以确定在待显示颜色为绿色时对应的第三驱动电压以及待显示颜色为蓝色时对应的第三驱动电压。In S730, when the to-be-displayed colors of the first image frame include two colors, the third driving voltage corresponding to each to-be-displayed color may be determined according to the second correspondence relationship. Taking the display panel including red, green and blue light-emitting sub-pixels as an example, when the first image frame includes green and blue, the corresponding third driving voltage and the corresponding third driving voltage when the color to be displayed is green can be determined according to the second corresponding relationship.

在S740中，在确定每种待显示颜色分别对应的第三驱动电压后，可以从多个第三驱动电压的最大值中确定第一驱动电压。即，在待显示颜色包括两种或两种以上的颜色时，可以确定各个待显示颜色分别对应的第三驱动电压，并将多个第三驱动电压的最大值作为第一驱动电压。In S740, after determining the third driving voltage corresponding to each color to be displayed, the first driving voltage may be determined from the maximum values of the multiple third driving voltages. That is, when the colors to be displayed include two or more colors, third driving voltages corresponding to each color to be displayed may be determined, and the maximum value of the multiple third driving voltages may be used as the first driving voltage.
在第一图像画面的待显示颜色包括绿色和蓝色，并确定待显示颜色为绿色时对应的第三驱动电压以及待显示颜色为蓝色时对应的第三驱动电压后，可以将两个第三驱动电压中的较大值作为第一驱动电压。The colors to be displayed in the first image frame include green and blue, and after determining the corresponding third driving voltage when the color to be displayed is green and the corresponding third driving voltage when the color to be displayed is blue, the two first The larger value among the three driving voltages is used as the first driving voltage.
需要说明的是，在显示面板包括三种颜色或三种以上颜色的发光子像素时，若第一图像画面的待显示颜色仅有一种，则该第一图像画面为待显示颜色对应的纯色画面。It should be noted that when the display panel includes light-emitting sub-pixels of three or more colors, if there is only one color to be displayed in the first image frame, the first image frame is a solid-color frame corresponding to the color to be displayed. .

在本实施例中，显示面板可以根据第一图像画面的缺失颜色或者待显示颜色来确定与第一图像画面对应的显示面板的第一驱动电压。根据当前亮度等级可以确定对应的第一电压系数，根据第一电压系数和第一驱动电压可以得到第五驱动电压。在该较低的第五驱动电压的驱动下，未缺失颜色的发光子像素仍能够满足发光亮度需求，从而在不影响第一图像画面的显示效果的基础上，进一步降低驱动电压，实现显示功耗的减小。In this embodiment, the display panel may determine the first driving voltage of the display panel corresponding to the first image frame according to the missing color or the color to be displayed of the first image frame. The corresponding first voltage coefficient can be determined according to the current brightness level, and the fifth driving voltage can be obtained according to the first voltage coefficient and the first driving voltage. Driven by the lower fifth driving voltage, the luminous sub-pixels with no missing color can still meet the requirement of luminous brightness, so that the driving voltage can be further reduced without affecting the display effect of the first image frame, and the display function can be realized. consumption reduction.
S810与上述实施例中的S610完全一致，S820与上述实施例中的S620完全一致，在此不再赘述。S810 is completely consistent with S610 in the foregoing embodiment, and S820 is completely consistent with S620 in the foregoing embodiment, and details are not repeated here.
在S830中，显示面板可以获取当前亮度等级，并根据当前亮度等级确定对应的第一电压系数。该第一电压系数可以与亮度等级对应的最大亮度值具有正相关关系。亮度等级越高，相同灰阶下对应的亮度越大。In S830, the display panel may acquire the current brightness level, and determine the corresponding first voltage coefficient according to the current brightness level. The first voltage coefficient may have a positive correlation with the maximum brightness value corresponding to the brightness level. The higher the brightness level, the greater the corresponding brightness under the same gray scale.
显示面板可以包括HDR(HighDynamicRangeImaging，高动态范围成像)、HBM(HighBrightnessMonitor，高亮度监视器)以及多个Normal亮度等级，不同的目标亮度等级对应的Gammaband下的最大亮度值并不相同。例如，HDR亮度等级和HBM亮度等级下各个发光子像素在最大灰阶下的亮度值较高，例如HDR亮度等级的最高灰阶下显示面板的亮度值可以达到1000nit或以上，HBM亮度等级下显示面板的亮度值可以达到700nit或以上。而多个Normal亮度等级可以分别对应460nit、300nit、120nit、60nit、20nit、10nit、6nit或其他发光亮度，在此不做限制。The display panel may include HDR (HighDynamicRangeImaging, high dynamic range imaging), HBM (HighBrightnessMonitor, high-brightness monitor) and multiple Normal brightness levels. Different target brightness levels correspond to different maximum brightness values under Gammaband. For example, under the HDR brightness level and HBM brightness level, the brightness value of each light-emitting sub-pixel at the maximum gray scale is relatively high. The brightness value of the panel can reach 700nit or above. The multiple Normal brightness levels can respectively correspond to 460nit, 300nit, 120nit, 60nit, 20nit, 10nit, 6nit or other luminous brightness, which is not limited here.
在显示面板的当前亮度等级对应的最大亮度值较高时，为了使得数据信号的电压变化范围对应较大的亮度变化范围，驱动芯片生成的数据信号参考电平VGSP、VGMP应当对应一个较大的电压区间，此时VGSP与VGMP的电压差值较大。而在当前亮度等级对应的最大亮度值较低时，数据信号的电压变化区间对应较小的亮度变化范围，此时数据信号的可调区间范围可以相应减小，即数据信号参考电平VGSP、VGMP的电压差值可以相应缩小。在参考电平VGSP、VGMP发生变化时，生成参考电平VGSP、VGMP的默认驱动电压也可以相应降低，以减小维持默认驱动电压所消耗的功率，从而降低显示面板的驱动功耗。When the maximum brightness value corresponding to the current brightness level of the display panel is high, in order to make the voltage variation range of the data signal correspond to a larger brightness variation range, the data signal reference levels VGSP and VGMP generated by the driver chip should correspond to a larger Voltage interval, at this time, the voltage difference between VGSP and VGMP is relatively large. When the maximum luminance value corresponding to the current luminance level is relatively low, the voltage variation interval of the data signal corresponds to a smaller luminance variation range. At this time, the adjustable interval range of the data signal can be correspondingly reduced, that is, the data signal reference level VGSP, The voltage difference of VGMP can be reduced accordingly. When the reference levels VGSP, VGMP change, the default driving voltages for generating the reference levels VGSP, VGMP can also be reduced accordingly, so as to reduce the power consumed to maintain the default driving voltage, thereby reducing the driving power consumption of the display panel.
可以理解的是，上述各个亮度等级与第二电压系数的对应关系也可以通过初始化存储的方式或者OTP(OneTimeProgrammable，一次性可编程)烧录的方式存储至驱动电压调整模块中。It can be understood that, the above-mentioned corresponding relationship between each brightness level and the second voltage coefficient can also be stored in the driving voltage adjustment module by means of initial storage or OTP (One Time Programmable, One Time Programmable) programming.
在S840中，在根据当前亮度等级确定对应的第一电压系数后，可以计算第一电压系数与第一驱动电压的乘积，得到第五驱动电压。In S840, after the corresponding first voltage coefficient is determined according to the current brightness level, the product of the first voltage coefficient and the first driving voltage may be calculated to obtain the fifth driving voltage.
在S850中，显示面板在确定第一图像画面对应的第五驱动电压后，可以在显示该图像画面时，将提供给显示面板的驱动芯片的默认驱动电压调整为第五驱动电压，以降低显示面板的显示功耗。In S850, after the display panel determines the fifth driving voltage corresponding to the first image frame, it can adjust the default driving voltage provided to the driving chip of the display panel to the fifth driving voltage when displaying the image frame, so as to reduce the display voltage. Display power consumption of the panel.
