It is to be understood that the mapping relationship is specifically an LUT (display look-up table) of the image signal and the white balance digital signal, and each time an image signal is input, the input image signal is looked up as an address, and then the white balance digital signal corresponding to the address is found according to the LUT, and then the white balance digital signal is output as the first digital signal.
It should be noted that the type of each pixel point in the display panel is obtained, and then the first digital signal is processed according to the type of the pixel point to obtain the second digital signal. The method comprises the steps that pixel points in a display panel are mainly main pixels and sub pixels, a terminal firstly obtains type identification of the pixel points, then determines the type of the pixel points according to the type identification, then obtains a corresponding LUT according to the type of the pixel points, and then uses a first digital signal as an address of the LUT to look up a table to find out a second digital signal corresponding to the address.

Further, referring to fig. 3, fig. 3 is a diagram illustrating an embodiment of a method for optimizing a picture of a display panel according to the present invention, and based on the embodiment, the step S10 includes:
step S11, when the type of the pixel point is a main pixel, processing the first digital signal according to a first mapping relation to obtain a second digital signal;
and step S12, when the type of the pixel point is a sub-pixel, processing the first digital signal according to a second mapping relationship to obtain the second digital signal, where the second digital signal obtained by the first mapping relationship is greater than the second digital signal obtained by the second mapping relationship.
In the technical solution provided in this embodiment, the mapping relationship is to first obtain a type of each pixel point in the display panel, and then process the first digital signal according to the type of the pixel point to obtain the second digital signal. The method comprises the steps that pixel points in a display panel are mainly main pixels and sub pixels, a terminal firstly obtains type identification of the pixel points, then determines the type of the pixel points according to the type identification, then obtains a corresponding LUT according to the type of the pixel points, and then uses a first digital signal as an address of the LUT to look up a table to find out a second digital signal corresponding to the address.
Further, when the type of the pixel point is a main pixel, obtaining an LUT corresponding to the main pixel point, then using the first digital signal as an input signal of the LUT, and using the input signal as an address to perform table lookup to find out data of the address, namely, a second digital signal corresponding to the main pixel point.

Further, referring to fig. 4, fig. 4 is a diagram illustrating an embodiment of a method for optimizing a picture of a display panel according to the present invention, and on the basis of the embodiment illustrated in fig. 2, the step S20 includes:
step S21, obtaining the color value of the pixel point according to the first digital signal;
and step S22, determining the weight value according to the relation among the color values.
In the technical scheme provided by this embodiment, after a first digital signal of each pixel point is obtained by processing an input image signal, a judgment equivalence module is obtained, and then a color value (R, G, B) of the pixel point based on the first digital signal is obtained by taking a pixel point (pixel) as a unit, and when R is equal to G and equal to B, the judgment equivalence module outputs a weight value (M _ gain) of 1. When R, G, B the three color values are not all equal, the decision equivalence module output weight value (M _ gain) is 0. For example, when the minimum value M (128, 0, 0) is calculated, R, G, B color values are not all equal, and the weight value corresponding to M is 0.
The terminal directly acquires the corresponding output signal without calculating the numerical ratio of the first digital signal and the numerical ratio of the second digital signal by acquiring the minimum value in the color values and judging whether the minimum value is 0 or 1, so that the efficiency of converting the image signal into the output signal is improved.
Further, referring to fig. 5, fig. 5 is a diagram illustrating an embodiment of a method for optimizing a picture of a display panel according to the present invention, and on the basis of the embodiment illustrated in fig. 4, the step S22 includes:
step S221, when the difference value between the color values is smaller than or equal to a preset threshold value, taking a first preset value as the weight value;
step S222, when the difference between the color values is greater than or equal to a preset threshold, taking a second preset value as the weight value.
In the technical solution provided in this embodiment, the first preset value may be 0, and the second preset value may be 1, after a first digital signal of each pixel point obtained by processing an input image signal is obtained, a color value of the pixel point based on the first digital signal is obtained, and then, with the pixel point as a unit, except for a pixel value at which two of three sub-pixels are compared with each other to be the smallest, the color value of the pixel point is subtracted from the color value of the pixel point by each other, and when a difference between the color values is smaller than or equal to a preset threshold, 0 is used as the weight value. And when the difference value between the color values is greater than or equal to a preset threshold value, taking 1 as the weight value. For example, the threshold is set to 50, M (128, 64, 0), two sub-pixels are subtracted from each other, the difference is greater than 50, and a second preset value is used as the weight value.
The terminal obtains the corresponding weight value according to the magnitude relation between the difference value and the preset threshold value by subtracting every two sub-pixels in the obtained color values, and the numerical value ratio of the first digital signal and the numerical value ratio of the second digital signal are not needed to be calculated, so that the efficiency of converting the image signal into the output signal is improved.
Further, referring to fig. 6, fig. 6 is a diagram illustrating an embodiment of a method for optimizing a display screen of a display panel according to the present invention, and on the basis of the embodiment illustrated in fig. 5, after the step S222, the method further includes:
step S60, when the weight value is equal to a first preset value, the first digital signal is used as the output signal;
and step S70, when the weight value is equal to a second preset value, using the second digital signal as the output signal.
In the technical solution provided in this embodiment, the first preset value is 0, the second preset value is 1, and the weight value is between 0 and 1. When the output signal is calculated, the value of the second digital signal is multiplied by the weight value to obtain the ratio of the second digital signal, 1 is subtracted from the weight value to obtain a second weight value, the value of the first digital signal is multiplied by the second weight value to obtain the ratio of the first digital signal, and finally the ratio of the first digital signal is added to the ratio of the second digital signal to obtain the value of the output signal. It is understood that, when the weight value is equal to the first preset value, the weight value is 0, that is, the ratio of the value of the second digital signal to the value of the output signal is 0, and the first digital signal is taken as the output signal. And when the weight value is equal to a second preset value, the weight value is 1, namely the ratio of the numerical value of the first digital signal in the numerical values of the output signals is 0, and the second digital signal is taken as the output signal.
And the terminal outputs a signal according to the characteristics of the weighted value after acquiring the weighted value, so that the optimization efficiency is improved.
Further, referring to fig. 7, fig. 7 is a flowchart illustrating an embodiment of an approval method based on task suspension according to the present invention, and on the basis of the embodiment illustrated in fig. 2, the step S10 includes:
step S13, when detecting that there is image signal input, obtaining the mapping relation between the image signal and the white balance digital signal;
and step S14, obtaining the first digital signal according to the mapping relation between the image signal and the white balance digital signal.
In the technical scheme provided by this embodiment, when detecting that an image signal is input, the terminal obtains a mapping relationship between the image signal and a white balance digital signal and obtains the first digital signal according to the mapping relationship between the image signal and the white balance digital signal. It is to be understood that the mapping relationship is specifically an LUT (display look-up table) of the image signal and the white balance digital signal, and each time an image signal is input, the input image signal is looked up as an address, and then the white balance digital signal corresponding to the address is found according to the LUT, and then the white balance digital signal is output as the first digital signal.
The terminal uses the input image signal as an address by displaying the lookup table, then searches the data content in the address and acquires the white balance digital signal, and can efficiently process the externally input image signal.
Further, referring to fig. 8, fig. 8 is a flowchart illustrating an embodiment of an approval method based on task suspension according to the present invention, and on the basis of the embodiment illustrated in fig. 2, after the step S30, the method further includes:
and step S80, generating a display picture according to the output signal.
In the technical scheme provided by this embodiment, when receiving a first digital signal of each pixel point obtained by processing an input image signal, a terminal processes the first digital signal according to the type of the pixel point to obtain a second digital signal; obtaining color values of the pixel points according to the first digital signals, and determining weight values according to the color values; and acquiring an output signal according to the first digital signal, the second digital signal and the weight value. After the terminal acquires the output signals of all the pixel points, corresponding voltages are provided for all the pixel points according to the output signals of all the pixel points, and then a display picture is generated.
It should be noted that, the frame generated by the display panel does not have grid vision while the white shift phenomenon of the frame at 45 ° left and right is solved under a large viewing angle, because when the minimum value of the color value is 0 or the minimum value is low, the value of the white balance digital signal is added to the value of the output signal of the sub-pixel, that is, the voltage of the sub-pixel is increased.
The terminal processes the input image signals into corresponding digital signals according to the types of the pixel points, obtains final image output signals according to the weighted values and generates display pictures according to the output signals, so that the problem of grid vision of the display panel caused by different types of pixel point voltages in the display panel is solved, and the watching experience of a user is improved.
