具体实施方式Detailed ways

这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with some aspects of the invention as recited in the appended claims.

由于液晶显示屏具有低成本的优势，故而短期内不会淘汰，而液晶显示屏的窄边框发展是显示行业的趋势，未来一定朝着极致窄边框发展。但是随着背光源border(边框)越来越窄，光源侧的遮光胶宽度越来越小，因此背光出现了新问题——灯口发黄，发黄区域如图1中的灰色区域。其原理是：LED(发光二极管)依靠蓝光芯片激发黄色荧光粉，LED在小角度的情况下，穿过荧光粉的距离较短，发出蓝光，画面显示正常。但在大角度的情况下，穿过荧光粉的距离较长，导致发出黄光。LED发出的光在通过LGP(导光板)时，蓝光的偏折角度大于黄光的偏折角度，黄光汇聚在灯口的附近区域，造成液晶显示屏在灯口附近的显示区域的画面偏黄。Due to the low-cost advantage of liquid crystal displays, they will not be eliminated in the short term, and the development of narrow borders of liquid crystal displays is the trend of the display industry, and it will definitely develop towards the ultimate narrow border in the future. However, as the border of the backlight source becomes narrower and the width of the shading glue on the light source side becomes smaller and smaller, a new problem occurs in the backlight - the lamp socket turns yellow, and the yellow area is the gray area in Figure 1. The principle is: LEDs (light emitting diodes) rely on blue light chips to excite yellow phosphors. When the LEDs pass through the phosphors at a small angle, the distance through the phosphors is short, emitting blue light, and the picture is displayed normally. But at large angles, the distance through the phosphor is longer, resulting in yellow light. When the light emitted by the LED passes through the LGP (light guide plate), the deflection angle of the blue light is greater than the deflection angle of the yellow light, and the yellow light is concentrated in the vicinity of the lamp socket, causing the LCD screen to be skewed in the display area near the lamp socket. yellow.

相关技术中，主要是采用在LED上方的FPC(柔性电路板)涂白油，然后反射出白光。但是随着边框越来越窄，会有大部分光不会经过上述反射，而是直接通过LGP到达液晶显示屏，仍然会存在上述“灯口发黄”的问题。In the related art, an FPC (flexible circuit board) above the LED is mainly used to apply white oil, and then reflect the white light. However, as the frame gets narrower and narrower, most of the light will not pass through the above reflection, but will directly reach the LCD screen through the LGP, and there will still be the above-mentioned problem of "yellowing of the lamp socket".

本公开提供了一种显示控制方法，应用于终端。该方法中，当检测到目标显示区域的局部区域的色度值与预设色度值的差值较大时，则通过调整上述局部区域的光通量，使得上述局部区域的色度值与预设色度值的差值变小，从而改善上述局部区域的显示效果，解决了目标显示区域的颜色显示不均匀的问题，使得整个目标显示区域的在任意灰阶情况下显示的颜色都更加均匀，提升了显示效果。The present disclosure provides a display control method, which is applied to a terminal. In this method, when it is detected that the difference between the chromaticity value of the local area of the target display area and the preset chromaticity value is large, the luminous flux of the local area is adjusted so that the chromaticity value of the local area is the same as the preset chromaticity value. The difference between the chromaticity values becomes smaller, thereby improving the display effect of the above-mentioned local area, solving the problem of uneven color display in the target display area, and making the color displayed in the entire target display area more uniform under any grayscale. Improved display.

在一个示例性实施例中，提供了一种显示控制方法，参考图2所示，该方法包括：In an exemplary embodiment, a display control method is provided. Referring to FIG. 2 , the method includes:

S210、获取组成目标显示区域的多个子区域中每个子区域的当前区域色度值。S210: Acquire the current regional chromaticity value of each sub-region of the multiple sub-regions that constitute the target display region.

该步骤中，目标显示区域可以是显示屏的整个显示区域，也可以是显示屏的局部显示区域，例如显示屏中靠近LED灯口位置的灯口区域。In this step, the target display area may be the entire display area of the display screen, or may be a partial display area of the display screen, such as the lamp port area in the display screen near the position of the LED lamp port.

当目标显示区域指显示屏的整个显示区域时，该方法用于调整整个显示区域的颜色显示的均匀性，使得整个目标显示区域的在任意灰阶情况下显示的颜色都更加均匀，提升了显示效果。When the target display area refers to the entire display area of the display screen, this method is used to adjust the uniformity of the color display of the entire display area, so that the color displayed in the entire target display area under any grayscale is more uniform, which improves the display. Effect.

当目标显示区域指靠近LED灯口位置的灯口区域时，该方法用于调整灯口区域的颜色显示的均匀性，以解决现有技术中的“灯口发黄”的问题，进而使得整个目标显示区域的在任意灰阶情况下显示的颜色都更加均匀，提升了显示效果。此时，该方法还包括：When the target display area refers to the lamp port area close to the position of the LED lamp port, this method is used to adjust the uniformity of the color display of the lamp port area, so as to solve the problem of "yellowing of the lamp port" in the prior art, so that the entire The color displayed in the target display area in any grayscale is more uniform, which improves the display effect. At this point, the method further includes:

确定显示区域中的灯口区域，作为目标显示区域。Determine the lamp socket area in the display area as the target display area.

其中，灯口区域指显示区域中靠近发光二极管的区域。当LED设置在终端的显示区域的第一端侧时，灯口区域则为靠近显示区域的第一端侧的区域。参考图1所示，LED设置在显示区域的低端侧，因此灯口区域则为靠近显示区域的低端侧的区域。Wherein, the lamp socket area refers to the area close to the light emitting diode in the display area. When the LED is arranged on the first end side of the display area of the terminal, the lamp socket area is an area close to the first end side of the display area. Referring to FIG. 1 , the LEDs are arranged on the low end side of the display area, so the lamp socket area is an area close to the low end side of the display area.

在一个实施方式中，目标显示区域指灯口区域，LED设置在显示区域的低端侧，终端中预设有设定尺寸，将距离显示区域低端侧设定尺寸内的区域作为灯口区域，设定尺寸具体为30cm。那么，距离显示区域低端侧30cm内的区域则为目标显示区域。In one embodiment, the target display area refers to the lamp port area, the LEDs are arranged on the low end side of the display area, the terminal is preset with a set size, and the area within the set size from the low end side of the display area is used as the lamp port area , the set size is 30cm. Then, the area within 30cm from the lower end of the display area is the target display area.

在一个实施方式中，目标显示区域指灯口区域，LED设置在显示区域的低端侧，显示区域的低端侧到顶端侧的尺寸为d，终端中预设有设定比例，设定比例例如30％。则将距离显示区域低端侧30％*d内的区域作为灯口区域。那么，距离显示区域低端侧30％*d内的区域则为目标显示区域。In one embodiment, the target display area refers to the light port area, the LEDs are arranged on the low end side of the display area, the size from the low end side to the top end side of the display area is d, and a preset ratio is preset in the terminal, and the set ratio For example 30%. Then, the area within 30%*d from the low end side of the display area is taken as the lamp socket area. Then, the area within 30%*d from the lower end of the display area is the target display area.

另外，在该步骤中，由于颜色包括色度和亮度，色度和亮度很难单独表示。并且，当显示屏的显示不均匀时，用户观察到的也是颜色的不均匀。因此，当前区域色度值可以指用于表示相应区域的色度的数据，也可以指用于表示相应区域的颜色的数据。In addition, in this step, since color includes chromaticity and luminance, it is difficult to express chromaticity and luminance separately. Moreover, when the display screen is not uniform, what the user observes is also the non-uniform color. Therefore, the chromaticity value of the current area may refer to data used to represent the chromaticity of the corresponding area, and may also refer to data used to represent the color of the corresponding area.

例如，当根据国际照委会制定的CIE1931色度图确定色度值时，可用红基色、绿基色和蓝基色的在某一颜色中的权重数据表示色度值。可以理解的，对于同一颜色，红基色、绿基色和蓝基色的权重之和应当为1，因此，也可直接通过上述三种基色的两种基色的权重数据表示某个颜色的色度值。For example, when the chromaticity value is determined according to the CIE1931 chromaticity diagram formulated by the International Licensing Commission, the chromaticity value can be represented by the weight data of the red primary color, the green primary color and the blue primary color in a certain color. It can be understood that for the same color, the sum of the weights of the red primary color, the green primary color and the blue primary color should be 1. Therefore, the chromaticity value of a certain color can also be directly represented by the weight data of the two primary colors of the above three primary colors.

当然，还可通过其他数据表示某个区域的色度值，在此不做赘述。Of course, the chromaticity value of a certain region can also be represented by other data, which will not be repeated here.

该步骤中要获取每个子区域的当前区域色度值，例如，目标显示区域被分成一万个子区域，则获取一万个当前区域色度值。目标显示区域被分成十万个子区域，则获取十万个当前区域色度值。具体的获取色度值的方法，可使用现有技术实现，在此不做赘述。In this step, the current area chromaticity value of each sub-area is to be obtained. For example, if the target display area is divided into 10,000 sub-areas, then 10,000 current area chromaticity values are obtained. The target display area is divided into 100,000 sub-areas, and 100,000 current area chromaticity values are obtained. The specific method for obtaining the chromaticity value can be implemented by using the prior art, and details are not described here.

该步骤中，每个子区域的尺寸可以相同，也可以不同。In this step, the size of each sub-region may be the same or different.

例如，当该方法用于去除“灯口偏黄”问题时，可以将目标显示区域中靠近灯口区域的位置分成尺寸更小、数量更多的子区域，将远离灯口区域的位置分成尺寸较大、数量较少的子区域。既能降低数据处理量，又能更好的实现对灯口区域的色度的改善。For example, when this method is used to remove the problem of "the lamp socket is yellowish", the position close to the lamp socket area in the target display area can be divided into sub-regions with smaller size and more number, and the position far from the lamp socket area can be divided into size Larger, smaller number of subregions. It can not only reduce the amount of data processing, but also better realize the improvement of the chromaticity of the lamp port area.

再例如，根据历史数据，确定某类终端的目标显示区域的中间位置容易出现偏红现象，则可以将该类终端的目标显示区域的中间位置设置尺寸较小、数量较多的子区域，在其他位置设置尺寸较大、数量较少的子区域。既能降低数据处理量，又能更好的实现对中间区域的色度的改善。For another example, according to historical data, it is determined that the middle position of the target display area of a certain type of terminal is prone to a reddish phenomenon, then the middle position of the target display area of this type of terminal can be set to a smaller size and a larger number of sub-areas, Other locations set larger and smaller sub-regions. It can not only reduce the amount of data processing, but also better realize the improvement of the chromaticity of the intermediate area.

另外，理论上，子区域最小可以为一个像素所表示的区域。当子区域为一个像素所表示的区域时，当前区域色度值则为一个像素的色度值，从而可以实现对目标显示区域进行更加精细化的显示控制。In addition, theoretically, the smallest sub-area can be the area represented by one pixel. When the sub-area is an area represented by a pixel, the chromaticity value of the current area is the chromaticity value of a pixel, so that more refined display control of the target display area can be achieved.

S220、确定色度差值大于或等于设定差值的子区域为目标区域。S220. Determine the sub-region whose chromaticity difference value is greater than or equal to the set difference value as the target region.

其中，色度差值为当前区域色度值与预设色度值的差值。可以理解的，当前区域色度值与预设色度值的表示方式应当是一致的。例如，当用红基色、绿基色和蓝基色的权重数据表示当前区域色度值时，同样也用红基色、绿基色和蓝基色的权重数据表示预设色度值。基于此，便可确定当前区域色度值与预设色度值的差值，即确定二者的色度差值。也就是说，该步骤中，色度差值是表示两个色度之间的差异的数据，其并不一定是固定的某个数值，也可以是一组数据。可以理解的，色度差值与设定差值的表示方式也应当一致，如此才可判断色度差值是否大于或等于设定差值。The chromaticity difference value is the difference between the chromaticity value of the current region and the preset chromaticity value. It can be understood that the representation manner of the chromaticity value of the current region and the preset chromaticity value should be consistent. For example, when the weight data of the red primary color, the green primary color, and the blue primary color are used to represent the chromaticity value of the current area, the preset chromaticity value is also represented by the weight data of the red primary color, the green primary color, and the blue primary color. Based on this, the difference between the chromaticity value of the current region and the preset chromaticity value can be determined, that is, the chromaticity difference value between the two can be determined. That is to say, in this step, the chromaticity difference value is data representing the difference between two chromaticities, which is not necessarily a fixed value, but may also be a set of data. It can be understood that the representations of the chromaticity difference and the set difference should also be consistent, so that it can be determined whether the chromaticity difference is greater than or equal to the set difference.

该步骤中，当某个子区域的当前区域色度值与预设色度值的差值大于或等于设定差值时，说明该子区域的色度偏差较为严重，则确定该子区域为目标区域。In this step, when the difference between the current regional chromaticity value of a certain sub-region and the preset chromaticity value is greater than or equal to the set difference value, it means that the chromaticity deviation of the sub-region is relatively serious, and the sub-region is determined as the target area.

S230、通过调整目标区域的光通量，调节目标区域的区域色度值至目标色度值。S230. Adjust the regional chromaticity value of the target area to the target chromaticity value by adjusting the luminous flux of the target area.

其中，目标色度值与预设色度值的色度差值小于设定差值。该步骤中，可以在终端中预设相应的目标色度值，也可不预设目标色度值，而是根据调整后的目标区域的区域色度值与预设色度值的色度差值确定是否达到目标色度值。Wherein, the chromaticity difference between the target chromaticity value and the preset chromaticity value is smaller than the set difference. In this step, the corresponding target chromaticity value may be preset in the terminal, or the target chromaticity value may not be preset, but the chromaticity difference value between the regional chromaticity value of the adjusted target area and the preset chromaticity value may be preset Determines whether the target chromaticity value is reached.

该步骤中，通过调整目标区域的光通量，可以改变该区域的显示情况。例如，调低红基色对应的光通量，则可降低该区域显示的颜色中的红基色的权重；调低绿基色的光通量，则可降低该区域显示的颜色中的绿基色的权重。In this step, by adjusting the luminous flux of the target area, the display condition of the area can be changed. For example, reducing the luminous flux corresponding to the red primary color can reduce the weight of the red primary color in the colors displayed in the area; reducing the luminous flux of the green primary color can reduce the weight of the green primary color in the colors displayed in the area.

该方法中，确定目标区域时，在显示屏进行纯色显示的状态下进行，以更好地确定存在偏差的子区域。例如，在显示屏进行白色显示的状态下，确定目标区域，既可以提高效率，又可提高准确率。In this method, when the target area is determined, it is carried out in the state where the display screen is displaying a solid color, so as to better determine the sub-area with deviation. For example, in the state where the display screen is displaying white, determining the target area can not only improve the efficiency, but also improve the accuracy.

当确定了目标区域后，对目标区域进行记录，例如通过目标区域的坐标进行记录。在后续使用该终端时，可以无需再确定目标区域，而是直接对记录中的目标区域进行光通量的调整，以使得整个目标显示区域的颜色显示更加均匀。当然，用户可设置用于重新确定目标区域的间隔时长，例如间隔时长为一个月或一年等，每隔间隔时长，则重新确定一次目标区域，重新确定目标区域后，将旧的目标区域的记录删除，形成新的目标区域的记录。After the target area is determined, the target area is recorded, for example, by the coordinates of the target area. When using the terminal subsequently, it is not necessary to determine the target area, but directly adjust the luminous flux of the target area in the recording, so that the color display of the entire target display area is more uniform. Of course, the user can set the interval for re-determining the target area, for example, the interval is one month or one year, etc., the target area is re-determined every interval, and after the target area is re-determined, the The record is deleted, forming a new target area record.

该方法中，当检测到目标显示区域的子区域的当前区域色度值与预设色度值的差值大于或等于设定差值时，则确定该子区域为目标区域，然后通过调整目标区域的光通量，使得目标区域的区域色度值与预设色度值的差值变为小于设定差值，从而改善目标区域的显示效果，解决目标显示区域的颜色显示不均匀的问题，使得整个目标显示区域的颜色显示更加均匀，提升显示效果。In this method, when it is detected that the difference between the current area chromaticity value and the preset chromaticity value of the sub-area of the target display area is greater than or equal to the set difference value, the sub-area is determined as the target area, and then the target area is adjusted by adjusting the target area. The luminous flux of the target area makes the difference between the regional chromaticity value of the target area and the preset chromaticity value become smaller than the set difference value, thereby improving the display effect of the target area and solving the problem of uneven color display in the target display area, making The color display of the entire target display area is more uniform, which improves the display effect.

在一个示例性实施例中，提供了一种显示控制方法，参考图3所示，在确定色度差值大于或等于设定差值的子区域为目标区域之前，该方法还包括：In an exemplary embodiment, a display control method is provided. Referring to FIG. 3 , before determining a sub-area whose chromaticity difference value is greater than or equal to a set difference value as a target area, the method further includes:

S310、确定当前区域色度值在色度图中的当前色度坐标。S310. Determine the current chromaticity coordinates of the chromaticity value of the current region in the chromaticity diagram.

其中，该装置中设置有预存数据包括色度图的数据。该步骤中，色度图的数据可以是国际照委会制定的CIE1931色度图，也可以是色度值与色度坐标的映射关系。当前色度坐标可以仅仅用横坐标(用于表示红基色的权重)和纵坐标(用于表示绿基色的权重)两个坐标表示，也可由横坐标(用于表示红基色的权重)、纵坐标(用于表示绿基色的权重)和竖坐标(用于表示蓝基色的权重)三个坐标表示。Wherein, the device is provided with pre-stored data including chromaticity diagram data. In this step, the data of the chromaticity diagram may be the CIE1931 chromaticity diagram formulated by the International Lighting Commission, or may be the mapping relationship between chromaticity values and chromaticity coordinates. The current chromaticity coordinate can be represented only by the abscissa (used to represent the weight of the red primary color) and the ordinate (used to represent the weight of the green primary color), or it can be represented by the abscissa (used to represent the weight of the red primary color), the vertical coordinate Coordinates (used to represent the weight of the green primary color) and vertical coordinates (used to represent the weight of the blue primary color) are represented by three coordinates.

在一个实施方式中，终端中直接预存有色度图。当获取了每个子区域的当前区域色度值后，便根据色度图确定每个当前区域色度值对应的当前色度坐标。当前色度坐标用横坐标(用于表示红基色的权重)和纵坐标(用于表示绿基色的权重)两个坐标表示。In one embodiment, a chromaticity map is directly pre-stored in the terminal. After the current regional chromaticity value of each sub-region is acquired, the current chromaticity coordinate corresponding to the chromaticity value of each current region is determined according to the chromaticity diagram. The current chromaticity coordinates are represented by two coordinates, the abscissa (used to represent the weight of the red primary color) and the ordinate (used to represent the weight of the green primary color).

在一个实施方式中，终端中的预存数据包括色度值与色度坐标的映射关系。色度坐标用横坐标(用于表示红基色的权重)、纵坐标(用于表示绿基色的权重)和竖坐标(用于表示蓝基色的权重)三个坐标表示。当获取了每个子区域的当前区域色度值后，便从上述映射关系中查找与该当前区域色度值对应的色度坐标，将查找到的色度坐标确定为该当前区域色度值的当前色度坐标。In one embodiment, the pre-stored data in the terminal includes a mapping relationship between chromaticity values and chromaticity coordinates. The chromaticity coordinates are represented by three coordinates: abscissa (used to represent the weight of the red primary color), ordinate (used to represent the weight of the green primary color), and vertical coordinate (used to represent the weight of the blue primary color). After the current region chromaticity value of each sub-region is obtained, the chromaticity coordinates corresponding to the current region chromaticity value are searched from the above mapping relationship, and the found chromaticity coordinates are determined as the chromaticity coordinates of the current region chromaticity value. The current chromaticity coordinates.

S320、确定目标区域的当前色度坐标与预设色度坐标的距离值。S320. Determine the distance value between the current chromaticity coordinates of the target area and the preset chromaticity coordinates.

其中，预设色度坐标指预设色度值在色度图中的坐标。该方法中，将预设色度值与色度图的数据分别设置，以便于用户根据需要单独调整预设色度值或预存数据。例如，当用户想要设置显示屏的显示状况为暖色调时，则可以调整预设色度值为暖色调的色度值，而无需调整色度图的数据；当用户想要设置显示屏的显示状况为冷色调时，则可以调整预设色度值为冷色调的色度值，而无需调整色度图的数据。The preset chromaticity coordinates refer to the coordinates of the preset chromaticity values in the chromaticity diagram. In this method, the preset chromaticity value and the data of the chromaticity diagram are set separately, so that the user can individually adjust the preset chromaticity value or the pre-stored data as required. For example, when the user wants to set the display condition of the display screen to be a warm tone, the preset chromaticity value can be adjusted to the chromaticity value of the warm tone without adjusting the data of the chromaticity diagram; When the display condition is cool tone, the preset chromaticity value can be adjusted to the chromaticity value of the cool tone without adjusting the data of the chromaticity diagram.

该步骤中，当确定了当前色度坐标和预设色度坐标后，根据二者的坐标，便可确定二者在色度图中的距离值。根据两点的坐标确定两点距离值的方法，可通过现有技术实现，在此不做赘述。In this step, after the current chromaticity coordinate and the preset chromaticity coordinate are determined, the distance value of the two in the chromaticity diagram can be determined according to the coordinates of the two. The method for determining the distance value of two points according to the coordinates of the two points can be realized by the prior art, and details are not described here.

S330、判断距离值与设定差值在色度图中的对应距离值之间的大小关系。S330. Determine the magnitude relationship between the distance value and the corresponding distance value in the chromaticity diagram of the set difference value.

可以理解的，预设色度坐标与当前色度坐标的距离值，即为预设色度值与当前区域色度值的色度差值在色度图中对应的距离值。因此，根据预设色度坐标与当前色度坐标的距离值，以及设定差值在色度图中的对应距离值之间的大小关系，便可确定色度差值与设定差值之间的大小关系。It can be understood that the distance value between the preset chromaticity coordinate and the current chromaticity coordinate is the distance value corresponding to the chromaticity difference between the preset chromaticity value and the chromaticity value of the current area in the chromaticity diagram. Therefore, according to the distance value between the preset chromaticity coordinate and the current chromaticity coordinate, and the magnitude relationship between the corresponding distance value of the set difference value in the chromaticity diagram, the difference between the chromaticity difference value and the set difference value can be determined. size relationship between.

S340、若距离值大于或等于对应距离值，则确定当前区域色度值与预设色度值的色度差值大于或等于设定差值。S340. If the distance value is greater than or equal to the corresponding distance value, determine that the chromaticity difference between the chromaticity value of the current region and the preset chromaticity value is greater than or equal to the set difference.

例如，某个子区域对应的当前区域色度坐标与预设色度坐标的距离值为2，设定差值在色度图中的对应距离值为1，则可确定该子区域的当前区域色度值与预设色度值的色度差值大于设定差值，该子区域则为目标区域。For example, if the distance between the chromaticity coordinates of the current region corresponding to a certain sub-region and the preset chromaticity coordinates is 2, and the corresponding distance value of the difference in the chromaticity diagram is set to be 1, the current regional color of the sub-region can be determined. If the chromaticity difference between the chromaticity value and the preset chromaticity value is greater than the set difference, the sub-area is the target area.

若距离值小于对应距离值，则确定当前区域色度值与预设色度值的色度差值小于设定差值。例如，某个子区域对应的当前区域色度坐标与预设色度坐标的距离值为0.5，设定差值在色度图中的对应距离值为1，则可确定该子区域的当前区域色度值与预设色度值的色度差值小于设定差值，该子区域则为目标区域。If the distance value is smaller than the corresponding distance value, it is determined that the chromaticity difference between the chromaticity value of the current area and the preset chromaticity value is smaller than the set difference. For example, if the distance between the chromaticity coordinates of the current region corresponding to a sub-region and the preset chromaticity coordinates is 0.5, and the corresponding distance value of the difference in the chromaticity diagram is set to be 1, the current regional color of the sub-region can be determined. If the chromaticity difference between the chromaticity value and the preset chromaticity value is smaller than the set difference, the sub-area is the target area.

在一个实施方式中，预存数据包括国际照委会制定的CIE1931色度图，在色度图中，横坐标表示红基色的权重，纵坐标表示绿基色的权重。确定的某个子区域的当前区域色度值在色度图中的位置如图4中的Q点所示，预设色度坐标如图4中的H点所示，其中H点为色度图中白色对应的坐标。如果Q点与H点的距离值大于对应距离值，则确定该子区域为目标区域，然后通过调整该目标区域的光通量，调节目标区域的区域色度值至目标色度值，使得目标区域的区域色度值与预设色度值的色度差值小于设定差值。也就是，将该目标区域的区域色度值对应的区域色度坐标由Q点的位置向H点位置的调节，以使得目标区域的区域色度坐标与预设色度坐标的距离值小于对应距离值。In one embodiment, the pre-stored data includes the CIE1931 chromaticity diagram formulated by the International Photographic Commission. In the chromaticity diagram, the abscissa represents the weight of the red primary color, and the ordinate represents the weight of the green primary color. The position of the determined chromaticity value of the current region of a certain sub-region in the chromaticity diagram is shown as the Q point in Figure 4, and the preset chromaticity coordinates are shown as the H point in Figure 4, where the H point is the chromaticity diagram The coordinates corresponding to the white color. If the distance value between point Q and point H is greater than the corresponding distance value, determine the sub-area as the target area, and then adjust the area chromaticity value of the target area to the target chromaticity value by adjusting the luminous flux of the target area, so that the target area is The chromaticity difference between the regional chromaticity value and the preset chromaticity value is less than the set difference. That is, the regional chromaticity coordinates corresponding to the regional chromaticity values of the target area are adjusted from the position of point Q to the position of point H, so that the distance value between the regional chromaticity coordinates of the target area and the preset chromaticity coordinates is less than the corresponding distance value.

该方法中，根据当前区域色度值在色度图中的当前色度坐标、预设色度值在色度图中的预设色度坐标以及设定差值在色度图中的对应距离值，确定当前区域色度值与预设色度值的色度差值是否大于或等于设定差值，进而确定相应的子区域是否为目标区域。该方法可以准确且快速地确定目标显示区域中的目标区域，从而便于进行显示状态的控制。In this method, according to the current chromaticity coordinates of the chromaticity value of the current region in the chromaticity diagram, the preset chromaticity coordinates of the preset chromaticity value in the chromaticity diagram, and the corresponding distance of the set difference value in the chromaticity diagram value, determine whether the chromaticity difference between the chromaticity value of the current area and the preset chromaticity value is greater than or equal to the set difference value, and then determine whether the corresponding sub-area is the target area. The method can accurately and quickly determine the target area in the target display area, thereby facilitating the control of the display state.

在一个示例性实施例中，提供了一种显示控制方法，该方法是对上述方法中步骤S230的改进。具体地，参考图5所示，调整目标区域对应的光通量，包括：In an exemplary embodiment, a display control method is provided, which is an improvement to step S230 in the above method. Specifically, referring to FIG. 5 , adjusting the luminous flux corresponding to the target area includes:

S510、确定当前色度坐标与预设色度坐标的坐标差值；S510, determining the coordinate difference between the current chromaticity coordinates and the preset chromaticity coordinates;

S520、根据坐标差值，调整目标区域对应的光通量。S520. Adjust the luminous flux corresponding to the target area according to the coordinate difference.

该方法中，坐标差值中的坐标存在正、负之分。根据坐标差值中的正和负便可确定光通量的调整方向(例如调低或调高)，从而更加方便、快捷地实现对显示屏的显示状态的调整。In this method, the coordinates in the coordinate difference value are divided into positive and negative. The adjustment direction of the luminous flux (for example, lower or higher) can be determined according to the positive and negative values of the coordinate difference, so that the display state of the display screen can be adjusted more conveniently and quickly.

在一个实施方式中，预存数据包括国际照委会制定的CIE1931色度图，在色度图中，横坐标表示红基色的权重，纵坐标表示绿基色的权重。某个目标区域的当前区域色度值在色度图中对应的当前色度坐标为(0.50，0.40)，预设色度值为白色的色度值，在色度图中对应的预设色度坐标为(0.30，0.32)，则确定的坐标差值为(0.20，0.08)。另外，由于根据上述色度图确定的坐标中，还隐含包括了竖坐标(用于表示蓝基色的权重)，也就是，当前色度坐标也可以表示为(0.50，0.40，0.10)，预设色度坐标表示为(0.30，0.32，0.38)，相应的坐标差值可以表示为(0.20，0.08，-0.28)，坐标差值中，横坐标、纵坐标和竖坐标之和为0。In one embodiment, the pre-stored data includes the CIE1931 chromaticity diagram formulated by the International Photographic Commission. In the chromaticity diagram, the abscissa represents the weight of the red primary color, and the ordinate represents the weight of the green primary color. The current region chromaticity value of a target area corresponds to the current chromaticity coordinates in the chromaticity diagram (0.50, 0.40), the preset chromaticity value is the chromaticity value of white, and the corresponding preset color in the chromaticity diagram The degree coordinates are (0.30, 0.32), then the determined coordinate difference is (0.20, 0.08). In addition, since the coordinates determined according to the above chromaticity diagram also implicitly include vertical coordinates (used to represent the weight of the blue primary color), that is, the current chromaticity coordinates can also be expressed as (0.50, 0.40, 0.10), the pre- Let the chromaticity coordinates be expressed as (0.30, 0.32, 0.38), and the corresponding coordinate difference can be expressed as (0.20, 0.08, -0.28). In the coordinate difference, the sum of the abscissa, the ordinate and the vertical coordinate is 0.

根据上述坐标差值可知，该目标区域的显示颜色中红基色和绿基色的权重较多，即，该目标区域的显示颜色偏黄。然后可通过调低该目标区域中红基色对应的光通量以及绿基色对应的光通量来实现对该目标区域显示状态的调整，使得该目标区域显示的颜色达到要求，不再偏黄。当然，也可通过调高该目标区域中蓝基色对应的光通量，实现对该目标区域显示状态的调整。或者，在调高该目标区域中蓝基色对应的光通量的同时，调低该目标区域中红基色对应的光通量以及绿基色对应的光通量。According to the above coordinate difference, it can be known that the display color of the target area has more weights of the red primary color and the green primary color, that is, the display color of the target area is yellowish. Then, the display state of the target area can be adjusted by lowering the luminous flux corresponding to the red primary color and the luminous flux corresponding to the green primary color in the target area, so that the color displayed in the target area meets the requirements and is no longer yellowish. Of course, the display state of the target area can also be adjusted by increasing the luminous flux corresponding to the blue primary color in the target area. Alternatively, while increasing the luminous flux corresponding to the blue primary color in the target area, the luminous flux corresponding to the red primary color and the luminous flux corresponding to the green primary color in the target area are decreased.

在一个实施方式中，预存数据包括国际照委会制定的CIE1931色度图，在色度图中，横坐标表示红基色的权重，纵坐标表示绿基色的权重。某个目标区域的当前区域色度值在色度图中对应的当前色度坐标为(0.20，0.40)，预设色度值为白色的色度值，在色度图中对应的预设色度坐标为(0.30，0.32)，则确定的坐标差值为(-0.10，0.08)。In one embodiment, the pre-stored data includes the CIE1931 chromaticity diagram formulated by the International Photographic Commission. In the chromaticity diagram, the abscissa represents the weight of the red primary color, and the ordinate represents the weight of the green primary color. The current area chromaticity value of a certain target area corresponds to the current chromaticity coordinates in the chromaticity diagram (0.20, 0.40), the preset chromaticity value is the chromaticity value of white, and the corresponding preset color in the chromaticity diagram The degree coordinate is (0.30, 0.32), then the determined coordinate difference is (-0.10, 0.08).

根据上述坐标差值可知，该目标区域的显示颜色中红基色的权重偏低、绿基色的权重偏多。然后便可通过调高该目标区域中红基色对应的光通量、调低该目标区域中绿基色对应的光通量，来实现对该目标区域显示状态的调整，使得该目标区域显示的颜色达到要求，确保整个显示屏各个位置的颜色的均匀性。According to the above coordinate difference, it can be known that in the display color of the target area, the weight of the red primary color is relatively low, and the weight of the green primary color is relatively high. Then, the display state of the target area can be adjusted by increasing the luminous flux corresponding to the red primary color in the target area and reducing the luminous flux corresponding to the green primary color in the target area, so that the color displayed in the target area meets the requirements, ensuring that Uniformity of color at various locations across the display.

在一个示例性实施例中，提供了一种显示控制方法，该方法是对上述方法中步骤S520的改进。具体地，根据坐标差值，调整目标区域的光通量，包括：In an exemplary embodiment, a display control method is provided, which is an improvement to step S520 in the above method. Specifically, according to the coordinate difference, adjust the luminous flux of the target area, including:

根据坐标差值，调整目标区域中子像素的液晶驱动电压。According to the coordinate difference, adjust the liquid crystal driving voltage of the sub-pixels in the target area.

每个目标区域包括一个或多个像素，每个像素对应有红色子像素、绿色子像素和蓝色子像素，每个子像素均对应一个液晶驱动电压，通过调整该液晶驱动电压，便可以控制该目标区域中相应子像素的光通量。Each target area includes one or more pixels, each pixel corresponds to a red sub-pixel, a green sub-pixel and a blue sub-pixel, and each sub-pixel corresponds to a liquid crystal driving voltage, and the liquid crystal driving voltage can be adjusted to control the The luminous flux of the corresponding sub-pixel in the target area.

该步骤中，目标区域中子像素包括红色子像素、绿色子像素和蓝色子像素中的至少一种。该方法中，通过调整目标区域中相应颜色子像素的液晶区驱动电压，来调整相应颜色的光通量，从而使得目标区域的区域色度值调整为目标色度值，确保整个目标显示区域的显示的均匀性，提升视觉效果。In this step, the sub-pixels in the target area include at least one of red sub-pixels, green sub-pixels and blue sub-pixels. In this method, the luminous flux of the corresponding color is adjusted by adjusting the driving voltage of the liquid crystal region of the corresponding color sub-pixel in the target area, so that the regional chromaticity value of the target area is adjusted to the target chromaticity value, so as to ensure the display of the entire target display area. Uniformity, enhance visual effect.

需要注意的是，当需要调整目标区域的红基色的光通量时，则通过调整该目标区域中每个红色子像素的液晶驱动电压实现对红基色的光通量的调整。It should be noted that when the luminous flux of the red primary color in the target area needs to be adjusted, the luminous flux of the red primary color is adjusted by adjusting the liquid crystal driving voltage of each red sub-pixel in the target area.

在一个实施方式中，预存数据包括国际照委会制定的CIE1931色度图。某个目标区域的当前区域色度值在色度图中对应的当前色度坐标为(0.50，0.40)，预设色度值为白色的色度值，在色度图中对应的预设色度坐标为(0.30，0.32)，则确定的坐标差值为(0.20，0.08)。在色度图中，横坐标表示红基色的权重，纵坐标表示绿基色的权重，根据上述坐标差值可知，该目标区域的显示颜色中红基色和绿基色的权重较多，即，该目标区域的显示颜色偏黄。In one embodiment, the pre-stored data includes the CIE1931 chromaticity diagram developed by the International Commission on International Photography. The current region chromaticity value of a target area corresponds to the current chromaticity coordinates in the chromaticity diagram (0.50, 0.40), the preset chromaticity value is the chromaticity value of white, and the corresponding preset color in the chromaticity diagram The degree coordinates are (0.30, 0.32), then the determined coordinate difference is (0.20, 0.08). In the chromaticity diagram, the abscissa represents the weight of the red primary color, and the ordinate represents the weight of the green primary color. According to the above coordinate difference, it can be known that the display color of the target area has more weights of the red primary color and the green primary color, that is, the target area has more weights. The display color of the area is yellowish.

然后可通过调低该目标区域中每个红色子像素的液晶驱动电压，以及该目标区域中每个绿色子像素的液晶驱动电压，实现对该目标区域显示状态的调整，使得该目标区域显示的颜色达到要求，不再偏黄。Then, the display state of the target area can be adjusted by lowering the liquid crystal driving voltage of each red sub-pixel in the target area and the liquid crystal driving voltage of each green sub-pixel in the target area, so that the display state of the target area can be adjusted. The color meets the requirements and is no longer yellowish.

当然，也可通过调高该目标区域中蓝色子像素的液晶驱动电压，实现对该目标区域显示状态的调整。但是，由于通常情况下，每个子像素的液晶驱动电压都是以最大电压进行工作，因此，一般无法调高子像素的液晶驱动电压，即，当出现偏黄情况时，一般通过调低该目标区域中每个红色子像素的液晶驱动电压，以及该目标区域中每个绿色子像素的液晶驱动电压，实现对该目标区域显示状态的调整。Of course, the display state of the target area can also be adjusted by increasing the liquid crystal driving voltage of the blue sub-pixels in the target area. However, since the liquid crystal driving voltage of each sub-pixel is usually operated at the maximum voltage, it is generally impossible to increase the liquid crystal driving voltage of the sub-pixel. The liquid crystal driving voltage of each red sub-pixel in the area and the liquid crystal driving voltage of each green sub-pixel in the target area realize the adjustment of the display state of the target area.

在一个示例性实施例中，提供了一种显示控制方法，参考图6所示，该方法中，调整目标区域中子像素的液晶驱动电压，包括：In an exemplary embodiment, a display control method is provided. Referring to FIG. 6 , in the method, adjusting the liquid crystal driving voltage of the sub-pixels in the target area includes:

S610、根据坐标差值，确定目标区域中子像素的液晶驱动电压的最大调整值；S610. Determine the maximum adjustment value of the liquid crystal driving voltage of the sub-pixels in the target area according to the coordinate difference;

S620、调整目标区域中子像素对应的液晶驱动电压时，液晶驱动电压的调整值小于或等于最大调整值。S620. When adjusting the liquid crystal driving voltage corresponding to the sub-pixel in the target area, the adjustment value of the liquid crystal driving voltage is less than or equal to the maximum adjustment value.

该方法中，目标色度值和预设色度值可以相同，也可以不同。In this method, the target chromaticity value and the preset chromaticity value may be the same or different.

当目标色度值与预设色度值相同时，将目标区域的区域色度值调整至目标色度值，也就是将目标区域的区域色度值调整至预设色度值。因此，根据上述坐标差值确地目标区域中子像素的液晶驱动电压的调整值后，则直接以此调整值作为变化值，来调整目标区域中子像素的液晶驱动电压，便可使得目标区域的区域色度值调整至目标色度值，确保整个目标显示区域的显示状态的均匀性。When the target chromaticity value is the same as the preset chromaticity value, the regional chromaticity value of the target area is adjusted to the target chromaticity value, that is, the regional chromaticity value of the target area is adjusted to the preset chromaticity value. Therefore, after the adjustment value of the liquid crystal driving voltage of the sub-pixel in the target area is determined according to the above coordinate difference, the adjustment value is directly used as the change value to adjust the liquid crystal driving voltage of the sub-pixel in the target area, so that the target area can be adjusted. The chromaticity value of the area is adjusted to the target chromaticity value to ensure the uniformity of the display state of the entire target display area.

当目标色度值与预设色度值不同时，将目标区域的区域色度值调整至目标色度值，指将目标区域的区域色度值向靠近预设色度值的色度值调整。因此，根据上述坐标差值确地目标区域中子像素的液晶驱动电压的调整值后，则可将上述调整值作为最大调整值，来调整目标区域中子像素的液晶驱动电压，只要调整至目标区域的区域色度值与预设色度值的色度差值小于设定差值即可，以提高显示控制效率。When the target chromaticity value is different from the preset chromaticity value, adjusting the regional chromaticity value of the target area to the target chromaticity value refers to adjusting the regional chromaticity value of the target area to the chromaticity value close to the preset chromaticity value . Therefore, after determining the adjustment value of the liquid crystal driving voltage of the sub-pixel in the target area according to the above coordinate difference, the above adjustment value can be used as the maximum adjustment value to adjust the liquid crystal driving voltage of the sub-pixel in the target area. The chromaticity difference between the regional chromaticity value of the region and the preset chromaticity value only needs to be smaller than the set difference value, so as to improve the display control efficiency.

需要注意的是，由于坐标差值是整个目标区域的当前色度坐标与预设色度坐标的差值，因此根据坐标差值确定目标区域中子像素的液晶驱动电压的最大调整值时，确定的是目标区域中相应颜色通道的液晶驱动电压的调整值，然后将确定的调整值作为该目标区域中相应颜色通道的颜色子像素的液晶驱动电压的最大调整值。It should be noted that since the coordinate difference is the difference between the current chromaticity coordinates of the entire target area and the preset chromaticity coordinates, when determining the maximum adjustment value of the liquid crystal driving voltage of the sub-pixels in the target area according to the coordinate difference, determine is the adjustment value of the liquid crystal driving voltage of the corresponding color channel in the target area, and then the determined adjustment value is used as the maximum adjustment value of the liquid crystal driving voltage of the color sub-pixels of the corresponding color channel in the target area.

例如，根据坐标差值确定的目标区域的红色通道的液晶驱动电压的调整值为A1，那么，该目标区域中每个红色子像素的液晶驱动电压的最大调整值均为A1。For example, if the adjustment value of the liquid crystal driving voltage of the red channel of the target area determined according to the coordinate difference is A1, then the maximum adjustment value of the liquid crystal driving voltage of each red sub-pixel in the target area is A1.

再例如，根据坐标差值确定的目标区域的红色通道的液晶驱动电压的调整值为A、绿色通道的液晶驱动电压为A2，那么，该目标区域中每个红色子像素的液晶驱动电压的最大调整值均为A1、每个绿色子像素的液晶驱动电压的最大调整值均为A2。For another example, the adjustment value of the liquid crystal driving voltage of the red channel of the target area determined according to the coordinate difference value is A, and the liquid crystal driving voltage of the green channel is A2, then, the maximum value of the liquid crystal driving voltage of each red sub-pixel in the target area is The adjustment values are all A1, and the maximum adjustment value of the liquid crystal driving voltage of each green sub-pixel is A2.

在一个示例性实施例中，提供了一种显示控制方法，参考图7所示，该方法中，调整目标区域中子像素的液晶驱动电压，包括：In an exemplary embodiment, a display control method is provided. Referring to FIG. 7 , in the method, adjusting the liquid crystal driving voltage of the sub-pixels in the target area includes:

S710、确定目标区域的子像素的当前液晶驱动电压。S710. Determine the current liquid crystal driving voltage of the sub-pixels in the target area.

该步骤中，可通过电压检测装置直接检测确定液晶驱动电压。当然，由于色度值、光通量以及液晶驱动电压之间存在一定的换算关系，因此也可根据当前区域色度值换算得到液晶驱动电压。上述方式均可通过现有技术实现，在此不做赘述。In this step, the liquid crystal driving voltage can be directly detected and determined by the voltage detection device. Of course, since there is a certain conversion relationship between the chromaticity value, the luminous flux, and the liquid crystal driving voltage, the liquid crystal driving voltage can also be obtained by conversion according to the chromaticity value of the current region. The above manners can be implemented by the prior art, which will not be described in detail here.

S720、确定当前液晶驱动电压与预设比例的乘积，作为电压调节梯度值。S720. Determine the product of the current liquid crystal driving voltage and the preset ratio as the voltage adjustment gradient value.

提前设置了预设比例，该预设比例可以是终端出厂时设置好的，也可以是用户使用该终端时，自行设置的。当然，用户也可根据需要自行修改该预设比例。A preset ratio is set in advance, and the preset ratio may be set when the terminal leaves the factory, or may be set by the user when using the terminal. Of course, the user can also modify the preset ratio according to their own needs.

电压调节梯度值指每次调整液晶驱动电压的调节值。例如，确定的目标区域的红色子像素的液晶驱动电压的电压梯度值为C，当调整该目标区域中红色子像素的液晶驱动电压时，每次将液晶驱动电压调整C。The voltage adjustment gradient value refers to the adjustment value for adjusting the liquid crystal driving voltage each time. For example, the voltage gradient value of the liquid crystal driving voltage of the red subpixel in the determined target area is C. When adjusting the liquid crystal driving voltage of the red subpixel in the target area, the liquid crystal driving voltage is adjusted by C each time.

在一个实施方式中，预设比例为10％，确定的目标区域包括三个红色子像素，其液晶驱动电压为D1、D2和D3。例如确定需要调低该目标区域中的红色子像素的液晶驱动电压。当调整该目标区域的上述红色子像素的液晶驱动电压时，则每次将其分别调低10％D1、10％D2和10％D3，直至调整后的目标区域的区域色度值至目标色度值。In one embodiment, the preset ratio is 10%, the determined target area includes three red sub-pixels, and the liquid crystal driving voltages thereof are D1, D2 and D3. For example, it is determined that the liquid crystal driving voltage of the red sub-pixel in the target area needs to be lowered. When adjusting the liquid crystal driving voltage of the above-mentioned red sub-pixels in the target area, it is adjusted down by 10% D1, 10% D2 and 10% D3 respectively each time until the area chromaticity value of the adjusted target area reaches the target color degree value.

该实施方式中，每次调整后，均需要确定调整后的目标区域的区域色度值与预设色度值的色度差值是否小于设定差值，如果结果为小于，则不再进行调整；如果结果为大于或等于，则继续以分别调低10％D1、10％D2和10％D3的方式调整目标区域中红色子像素的液晶驱动电压，直至调整后的目标区域的区域色度值与预设色度值的色度差值小于设定差值。In this embodiment, after each adjustment, it is necessary to determine whether the chromaticity difference between the regional chromaticity value of the adjusted target area and the preset chromaticity value is less than the set difference value. Adjust; if the result is greater than or equal to, continue to adjust the liquid crystal driving voltage of the red sub-pixels in the target area by 10% D1, 10% D2 and 10% D3 respectively, until the adjusted target area has a regional chromaticity The chromaticity difference between the value and the preset chromaticity value is less than the set difference.

When adjusting the liquid crystal driving voltage of the red sub-pixels in the target area, it is lowered by d each time until the adjusted regional chromaticity value of the target area reaches the target chromaticity value.

该实施方式中，每次调整后，均需要确定调整后的目标区域的区域色度值与预设色度值的色度差值是否小于设定差值，如果结果为小于，则不再进行调整；如果结果为大于或等于，则继续以分别调低d的方式调整目标区域中红色子像素的液晶驱动电压，直至调整后的目标区域的区域色度值与预设色度值的色度差值小于设定差值。In this embodiment, after each adjustment, it is necessary to determine whether the chromaticity difference between the regional chromaticity value of the adjusted target area and the preset chromaticity value is less than the set difference value.
