These large-load display panels are prone to abnormalities when the display device is switched between light load and heavy load when displaying some special images.
这是因为不同负载下，数据驱动对于IC模拟电压的拉动大小不一。轻负载下，数据驱动对于IC模拟电压的拉动较小；而重负载下，数据驱动对于IC模拟电压的拉动较大。This is because under different loads, the data driver pulls the IC analog voltage differently. Under light load, the data driver pulls less on the IC analog voltage; while under heavy load, the data driver pulls more on the IC analog voltage.
针对现有的显示面板，在轻负载和重负载切换时，数据驱动不能及时切换到对应的画面的负载下，使得IC模拟电压出现波动，引起显示异常。For the existing display panel, when the light load and heavy load are switched, the data driver cannot be switched to the load of the corresponding screen in time, which causes the IC analog voltage to fluctuate, causing abnormal display.

由于不同的面板的驱动方式，导致在画面切换时，不同像素列对应的数据电压的切换方式不同，本申请对此不一一介绍。以列翻转液晶显示屏、每个像素中包含红(R)、绿(G)、蓝(B)三个子像素为例。对于列反转驱动方式表现为，相邻数据线上对应的子像素以列为单元正负极性反转。列反转的驱动波形以一帧时间为单位。Due to the different driving methods of the panels, the switching methods of the data voltages corresponding to different pixel columns are different when the screen is switched, and this application will not introduce them one by one. Taking a column flipped liquid crystal display as an example, each pixel includes three sub-pixels of red (R), green (G), and blue (B). For the column inversion driving mode, the positive and negative polarities of the sub-pixels corresponding to the adjacent data lines are reversed in units of columns. The driving waveform of column inversion takes one frame time as a unit.
另外需要说明的是，在本申请实施例中，所述预设周期T可以根据不同的器件以及应用场景进行设定，本申请对此并不限制，对于精度要求较高的应用场景，可以将预设周期T设定为较低数值，当然预设周期T可以为一帧显示周期，还可以包括半个显示周期或者多个显示周期。In addition, it should be noted that in the embodiment of the present application, the preset period T can be set according to different devices and application scenarios. The preset period T is set to a relatively low value. Of course, the preset period T may be a frame display period, or may include half a display period or multiple display periods.
对于画面显示时，不同灰阶数根据不同频率或者驱动方式的不同，也存在不同的变换。例如，如当前帧显示画面的刷新频率为85赫兹，在85赫兹的刷新频率下对应的画面的显示灰阶为L1，而在待显示画面的刷新频率变为75赫兹，在75赫兹的刷新频率下对应的画面的显示灰阶为L2。由于显示画面在刷新频率为85Hz时对应的显示灰阶为L1，在刷新频率为75Hz时对应的显示灰阶为L2。For screen display, there are different transformations for different gray scales according to different frequencies or different driving methods. For example, if the refresh rate of the display screen of the current frame is 85 Hz, the display gray scale of the corresponding screen at the refresh rate of 85 Hz is L1, and the refresh rate of the screen to be displayed becomes 75 Hz, and at the refresh rate of 75 Hz The display gray scale of the corresponding picture below is L2. Since the display gray scale corresponding to the display screen is L1 when the refresh frequency is 85 Hz, and the corresponding display gray scale is L2 when the refresh frequency is 75 Hz.
另外，在进行画面显示时，为了实现跨多灰阶时的数据转化速率，在同一根数据通道上，先后输出三个或四个数据，例如，输出白色灰阶数据L3、红色灰阶数据L4、蓝色灰阶数据L5、绿色灰阶数据L6(也就是1：4的结构)。因此，在每次翻转时，对于同一列上的跨灰阶数也是不同的，单列灰阶差b0＝(L4-L3)+(L5-L4)+(L6-L5)。对于不同实施例中，还可以能存在其他驱动方式，本申请并不限制。In addition, when displaying the screen, in order to achieve the data conversion rate across multiple gray scales, three or four data are successively output on the same data channel, for example, white gray scale data L3 and red gray scale data L4 are output. , blue grayscale data L5, green grayscale data L6 (that is, the structure of 1:4). Therefore, when flipping each time, the number of gray scales across the same column is also different, and the gray scale difference of a single column b0=(L4-L3)+(L5-L4)+(L6-L5). For different embodiments, there may also be other driving modes, which are not limited in this application.
在本申请实施例中，通过将画面的负载以整个面板的翻转次数a和跨灰阶数来进行总体评价，避免对于部分画面的灰阶变换不均与导致计算精度降低。In the embodiment of the present application, the load of the screen is evaluated by the number of flips a of the entire panel and the number of gray scales crossed, so as to avoid uneven gray scale transformation of some screens and reduce calculation accuracy.
在本申请的另一个实施例中，在所述步骤S04中，基于所述当前帧画面和待显示画面，获取所述显示信息，方法包括：In another embodiment of the present application, in the step S04, the display information is acquired based on the current frame picture and the picture to be displayed, and the method includes:
S211、在所述显示面板中选定参考像素列。S211. Select a reference pixel column in the display panel.
S212、基于所述当前帧画面和所述待显示画面，获取所述参考像素列在所述预设周期T内的数据电压的单列翻转次数a0和每翻转一次对应的单列灰阶差b0。S212. Based on the current frame picture and the picture to be displayed, acquire the single-column inversion times a0 of the data voltage of the reference pixel column in the preset period T and the corresponding single-column grayscale difference b0 for each inversion.
S213、基于所述单列翻转次数a0和单列灰阶差b0，获取所述预设周期T内的翻转次数a和翻转跨灰阶数b，其中，所述翻转次数a等于所述单列翻转次数a0的总和，所述翻转跨灰阶数b等于各个所述单列灰阶差b0的总和。S213. Based on the number of flips a0 in a single column and the gray-scale difference b0 in a single row, obtain the number of flips a and the number of gray-scales b of flips in the preset period T, where the number of flips a is equal to the number of flips a0 in a single row The sum of the number of inverted gray scales b is equal to the sum of the individual column gray scale differences b0.
其中，所述选定参考像素列的选取规则，本申请并不限制，在一些实施例中，可以为随机挑选规则，或者是固定位置的挑选规则，当然还可以采用的是，通过判断在预设周期T内的变换波动最大的所在像素列，例如单列翻转次数a0最大的一列，或者单列灰阶差b0最高的一列，或者灰阶差的总和最大的一列，本申请对此并限制。当然，按照变换较为剧烈的像素列，通过该标准计算后的推力大小可以实现更高推力的效果。Wherein, the selection rule of the selected reference pixel column is not limited in this application. In some embodiments, it may be a random selection rule, or a fixed position selection rule. Assume that the pixel column with the largest transformation fluctuation within the period T is located, for example, the column with the largest single-column flip times a0, or the column with the highest single-column grayscale difference b0, or the column with the largest sum of grayscale differences. This application does not limit this. Certainly, according to the pixel column with relatively severe transformation, the thrust value calculated by this standard can achieve a higher thrust effect.
需要说明的是，参考像素列的选取规则可以根据不同器件或者应用场景的不同，进行不同的选择，本申请对此并不限制。当然，还可以通过选择多个参考像素列的方式。根据不同的选取规则，在设定不同驱动模式对应的显示信息阈值时，可以进行适当的调整。It should be noted that the selection rules of the reference pixel columns may be selected differently according to different devices or different application scenarios, which is not limited in this application. Of course, it is also possible to select multiple reference pixel columns. According to different selection rules, appropriate adjustments can be made when setting the display information thresholds corresponding to different driving modes.
在本申请实施例中，像素列的翻转次数a当前帧像素布置、刷新频率及显示面板的驱动方式有关，像素列每次翻转时的跨灰阶数与显示面板的显示方案有直接关系。对于待显示画面和当前帧显示画面而言，当前帧显示画面和待显示画面可能处于同一灰阶，但是两帧对应的刷新频率却存在差异。因此，在获取翻转次数a和跨灰阶数都可能产生不同。因此，在本申请实施例中，对于翻转次数a和跨灰阶数进行同步判断，来评价负载情况。In the embodiment of the present application, the number of flips a of the pixel row is related to the current frame pixel arrangement, the refresh frequency and the driving mode of the display panel, and the number of gray scales when the pixel row is flipped each time is directly related to the display scheme of the display panel. Regarding the picture to be displayed and the picture to be displayed in the current frame, the picture to be displayed in the current frame and the picture to be displayed may be in the same gray scale, but the refresh rates corresponding to the two frames are different. Therefore, there may be differences in obtaining the number of flips a and the number of gray scales crossed. Therefore, in the embodiment of the present application, synchronous judgment is performed on the number of flips a and the number of gray scales crossed to evaluate the load situation.
在本申请的实施例中，对于数据驱动模式的设置个数，本申请不作限制，划分的越细致，可以采用的推力值的变换调整越细致，以产生较好的调整效果。在应用时，可以根据应用器件和应用场景进行不同的设置。在本申请实施例中，以数据驱动模式为三个进行示例性说明。In the embodiment of the present application, the present application does not limit the number of data-driven modes to be set, and the finer the division, the finer the transformation and adjustment of the thrust value that can be used, so as to produce a better adjustment effect. In application, different settings can be made according to the application device and application scenario. In the embodiment of the present application, three data-driven modes are used as examples for illustration.
所述数据驱动模式包括第一驱动模式N1、第二驱动模式N2、第三驱动模式N3；其中，所述步骤S08中，基于所述显示信息和所述显示信息阈值范围确定对应的所述驱动模式，如图3所示，方法包括：The data driving mode includes a first driving mode N1, a second driving mode N2, and a third driving mode N3; wherein, in the step S08, the corresponding driving mode is determined based on the display information and the threshold range of the display information. mode, as shown in Figure 3, the methods include:

需要说明的是，在本申请实施例中，以双重判断标准来画面的负载情况，避免仅通过单一的条件产生的判断误差，提高判断精度，可以防止由于判断不准确导致的波形出现波动，造成显示异常。图4所示为通过单一条件判断后出现的显示异常的波形图；图5为通过本申请实施例中通过双重条件判断后的显示图形。在本申请实施例中，由于负载从轻负载切换到重负载情况下，在AVDD电压处发生压降，导致S-IC出现波形失真，本申请实施例中，通过改变推力大小，使得电平更早恢复，使得电平可以正确写入像素中，避免显示异常。It should be noted that, in the embodiment of the present application, the load condition of the screen is judged by double judging criteria, which avoids judging errors caused by only a single condition, improves judgment accuracy, and prevents waveform fluctuations caused by inaccurate judgments, resulting in Display Error. Fig. 4 is a waveform diagram of abnormal display after judging by a single condition; Fig. 5 is a display graph after judging by double conditions in the embodiment of the present application. In the embodiment of this application, when the load is switched from light load to heavy load, a voltage drop occurs at the AVDD voltage, resulting in waveform distortion on the S-IC. Early recovery, so that the level can be correctly written into the pixel, to avoid abnormal display.
例如，当由白色(W L255)切换Skip pixel画面(同一行像素亮暗相间，且同一列像素亮暗相间的画面)，采用的是第三驱动模式；当由白色(W L255)切换Skip 1V line画面(子像素一行亮一行暗的画面)，采用的是第二驱动模式；当由白色(W L255)Skip sub-pixel画面(同一行子像素亮暗相间，且同一列子像素亮暗相间的画面)，采用的是第一驱动模式。For example, when the Skip pixel screen is switched from white (W L255) (a screen in which the pixels in the same row are alternately bright and dark, and the pixels in the same column are alternately bright and dark), the third driving mode is used; when switching from white (W L255) to Skip 1V line screen (the screen with one row of sub-pixels bright and one row of dark), adopts the second driving mode; screen), the first drive mode is used.
在本申请实施例中，所述数据驱动模式对应不同的驱动参数；其中S10，基于所述确定对应的所述驱动模式，对所述显示面板进行显示驱动，包括：In the embodiment of the present application, the data driving mode corresponds to different driving parameters; wherein S10, based on the determined corresponding driving mode, performs display driving on the display panel, including:

在本申请实施例中，不同数据驱动模式对应的驱动参数可以为一精确值，还可以为一范围值，本申请对此并不限制，例如采用的是a％的比例，本领域技术人员可以根据实际情况进行调整，示例性的，可以取值50％～100％的范围中的某个数值，例如取值为50％、60％、65％、70％、75％、85％、90％等，本发明对此不做限定。当然，驱动参数的设置可以根据模拟值进行设定本申请对此并不限制。In the embodiment of the present application, the driving parameters corresponding to different data driving modes can be a precise value or a range value, which is not limited in the present application, for example, the ratio of a% is used, and those skilled in the art can Adjust according to the actual situation. Exemplarily, a certain value in the range of 50% to 100% can be used, such as 50%, 60%, 65%, 70%, 75%, 85%, 90% etc., the present invention is not limited thereto. Of course, the setting of the driving parameters can be set according to the simulated value, and the present application does not limit this.
