Background
With the development of liquid crystal display technology, people have higher and higher requirements for the display quality of liquid crystal display. For the display mode of Vertical Alignment (VA), the contrast ratio is higher, and the rubbing treatment is not needed in the manufacturing process, so the production efficiency is improved, and the application is wider. However, in the VA display, since the VA display is vertically aligned, the viewing angle is relatively poor. For a 4-domain pixel design, poor viewing angle of the panel may cause a color wash out phenomenon. In order to improve the viewing angle, the display panel is subjected to picture compensation at different viewing angles.
However, due to the limitation of programming, the conventional view compensation technology can only generate an optimized picture with a specific optimization degree. This results in limited improvement of the viewing angle of the panel, and the limited optimization degree of the panel for different processes is difficult to meet the requirements of various viewing angle specifications.

First, an embodiment of the present invention provides a method for optimizing a display panel, where the display panel includes a plurality of pixels.
The method comprises the following steps: determining an initial gray scale displayed before optimization of a target pixel by taking any pixel in a plurality of pixels as the target pixel; performing first compensation optimization on the initial gray scale to obtain a first compensation gray scale and a second compensation gray scale, wherein the first compensation gray scale is larger than the initial gray scale, and the second compensation gray scale is smaller than the initial gray scale; performing second compensation optimization on the second compensation gray scale to obtain a third compensation gray scale corresponding to the first optimization degree and a fourth compensation gray scale corresponding to the second optimization degree; obtaining a fifth compensation gray scale for optimizing the picture of the display panel according to the third compensation gray scale and the fourth compensation gray scale; determining a sixth compensation gray scale for optimizing the picture of the display panel according to the fifth compensation gray scale and the initial gray scale; and when the display panel displays a picture, optimizing the target pixel according to the fifth compensation gray scale and the sixth compensation gray scale.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating an embodiment of a display panel picture optimization method according to an embodiment of the present disclosure. As shown in fig. 2, the display panel picture optimization method includes the following steps:
21. and determining the initial gray scale displayed before the target pixel is not optimized by taking any pixel in the plurality of pixels as the target pixel.
22. And performing first compensation optimization on the initial gray scale to obtain a first compensation gray scale and a second compensation gray scale.
In the embodiment of the present application, in order to solve the viewing angle problem of the display panel, compensation optimization is performed on the picture of the display panel. Specifically, any pixel of a plurality of pixels in the display panel may be used as a target pixel, and an initial gray scale displayed before optimization of the target pixel is determined; performing first compensation optimization on the initial gray scale to obtain an initial first compensation gray scale and a second compensation gray scale; and compensating the display panel by using the first compensation gray scale and the second compensation gray scale.
However, in different types of display panels in the prior art, the first uncompensated gray scale and the second compensated gray scale corresponding to the target pixel with the same gray scale value are the same; however, for different types of display panels, other display problems may occur, and it is still impossible to achieve a better display screen for each display panel. Therefore, the compensation gray scale needs to be adjusted continuously.
In one embodiment, the initial gray level corresponding to the target pixel is 128, and after the first compensation optimization, the initial gray level 128 is changed into the first compensation gray level 150(Highcode) and the second compensation gray level 50 (Lowcode). Under normal conditions, the gray scale value of the first compensation gray scale is greater than the gray scale value corresponding to the initial gray scale, and the gray scale value corresponding to the second compensation gray scale is less than the gray scale value corresponding to the initial gray scale; therefore, the gray scale value of the first compensation gray scale is larger than that of the second compensation gray scale.
23. And performing second compensation optimization on the second compensation gray scale to obtain a third compensation gray scale corresponding to the first optimization degree and a fourth compensation gray scale corresponding to the second optimization degree.
The first compensation gray scale and the second compensation gray scale are two compensation gray scales corresponding to the initial gray scale of the target pixel in the prior art, but for different display panels, other display problems may occur when the same first compensation gray scale and second compensation gray scale are used for compensating the picture, so that the first compensation gray scale and the second compensation gray scale need to be adjusted.
In the embodiment of the application, the smaller second compensation gray scale is mainly adjusted to obtain the smaller compensation gray scale in the final compensation gray scale, the corresponding larger compensation gray scale is calculated according to the adjusted smaller compensation gray scale, and the display panel is compensated by using the two adjusted compensation gray scales.
Specifically, the second compensation gray scale can be calculated to obtain a plurality of compensation gray scales with different optimization degrees; in the embodiment of the present application, a third compensation gray scale of the first optimization degree and a fourth compensation gray scale of the second optimization degree are mainly calculated.
24. And obtaining a fifth compensation gray scale for optimizing the picture of the display panel according to the third compensation gray scale and the fourth compensation gray scale.
The third compensation gray scale and the fourth compensation gray scale are actually obtained by optimizing the original second compensation gray scale to different degrees. In the embodiment of the present application, after the third compensation gray scale and the fourth compensation gray scale are determined, a fifth compensation gray scale may be obtained by using the third compensation gray scale and the fourth compensation gray scale. Wherein, the fifth compensation gray scale can be understood as: the second compensation gray scale is obtained after other optimization degrees different from the first optimization degree and the second optimization degree are carried out. And when the fifth compensation gray scale is obtained through calculation, the second compensation gray scale is not directly calculated, but the third compensation gray scale and the fourth compensation gray scale are used for calculation, so that the calculation precision can be effectively improved, and the second compensation gray scale with larger original error still has larger error after calculation to influence the picture display.
25. And determining a sixth compensation gray scale for optimizing the picture of the display panel according to the fifth compensation gray scale and the initial gray scale.
In the embodiment of the present invention, an initial gray level is optimized to obtain a set of two associated compensation gray levels (i.e. Highcode and Lowcode), and the gray levels of the two compensation gray levels are different. In the foregoing embodiment, only the fifth compensation gray scale is obtained, and therefore a sixth compensation gray scale associated with the fifth compensation gray scale needs to be obtained; the fifth compensation gray scale and the sixth compensation gray scale are both gray scales required for optimizing the display panel.
In the embodiment of the present application, the fifth compensation gray scale and the initial gray scale may be determined, and the other compensation gray scale except the fifth compensation gray scale is selected from the two final compensation gray scales corresponding to the initial gray scale after compensation optimization. The fifth compensation gray scale and the initial gray scale are used for determining a sixth compensation gray scale, and the fifth compensation gray scale and the sixth compensation gray scale are two compensation gray scales obtained after the initial gray scale is optimized by using the display panel picture optimization method provided by the embodiment of the application.
26. And when the display panel displays a picture, optimizing the target pixel according to the fifth compensation gray scale and the sixth compensation gray scale.
According to the display panel picture optimization method provided by the embodiment of the application, a first compensation gray scale and a second compensation gray scale corresponding to the first compensation optimization are obtained, and the first compensation gray scale is larger than the second compensation gray scale; then, calculating by using a second compensation gray scale with a smaller numerical value to obtain a third compensation gray scale and a fourth compensation gray scale under different optimization degrees; and interpolating the third compensation gray scale and the fourth compensation gray scale to obtain a fifth compensation gray scale corresponding to other optimization degrees, and calculating to obtain a sixth compensation gray scale corresponding to the optimized initial gray scale according to a first brightness corresponding to the fifth compensation gray scale and a second brightness corresponding to the initial gray scale before optimization, so as to optimize the picture of the display panel according to the fifth compensation gray scale and the sixth compensation gray scale. By optimizing for multiple times in the embodiment of the application, the optimal picture optimization degrees corresponding to different display panels can be determined, the picture optimization precision is improved, and the difference of picture optimization of different display panels is realized.
As shown in fig. 3, a schematic diagram of an embodiment of calculating a third compensation gray scale and a fourth compensation gray scale provided in the present application may include:
31. and calculating to obtain a third compensation gray scale corresponding to the first optimization degree according to a preset first adjustment ratio and the second compensation gray scale.
32. And calculating to obtain a third compensation gray scale corresponding to the second optimization degree according to the preset second adjustment ratio and the second compensation gray scale.
In the embodiments of the present application, the degree of optimization actually means: a first difference value between the gray scale obtained after the second compensation gray scale optimization and the initial gray scale, a second difference value between the gray scale obtained before the second compensation gray scale optimization and the initial gray scale, and a ratio of the first difference value to the second difference value.
Taking the initial gray scale 128, the first compensation gray scale 150, and the second compensation gray scale 50 as an example, the second difference between the second compensation gray scale 50 and the initial gray scale 128 is 128-50-78; if the first optimization degree (i.e. the first adjustment ratio) is 100%, it means that the difference between the value of the third compensation gray scale obtained after the optimization of the second compensation gray scale 50 and the initial gray scale 128 is 78 percent, i.e. the third compensation gray scale is 50.
If the second optimization degree (i.e. the second adjustment ratio) is 75%, the fourth compensation gray scale is: the ratio of the first difference 58.5 between the fourth compensated gray level and the initial gray level and the second difference 70 between the second compensated gray level and the initial gray level is 128- (128-50) × 0.75 ═ 69.5.
In general, the first adjustment ratio is greater than the second adjustment ratio, but the third compensation gray scale corresponds to a gray scale value smaller than the fourth compensation gray scale value. This is because the larger the adjustment ratio, the larger the difference between the optimized compensated gray scale and the initial gray scale.
In the embodiment of the present application, the first adjustment ratio is typically 100%, and the second adjustment ratio is typically 75%. In other embodiments, the first adjustment ratio and the second adjustment ratio may also be adjusted according to the actual requirement of the display panel, which is not limited herein.
It should be noted that, in the embodiment of the present application, if the third compensation gray scale and the fourth compensation gray scale are not integers, rounding up is performed on the third compensation gray scale and the fourth compensation gray scale to obtain rounded third compensation gray scale and rounded fourth compensation gray scale.
After the third compensation gray scale and the fourth compensation gray scale are determined, a fifth compensation gray scale can be further calculated. Specifically, the third compensation gray scale and the fourth compensation gray scale may be interpolated by using a preset interpolation method to obtain a fifth compensation gray scale.
In the embodiment of the present application, the fifth compensation gray scale may be understood as data obtained by optimizing the second compensation gray scale by other optimization degrees, but the actual calculation is not performed by using the second compensation gray scale, but is performed by using the third compensation gray scale and the fourth compensation gray scale.
In embodiments of the present application, the degree of optimization (or the adjustment ratio) may be greater than one hundred percent. In one embodiment, a linear interpolation may be used to obtain a fifth compensation gray level corresponding to an optimization level of 130% compared to the second compensation gray level. The method comprises the following specific steps:
the fifth compensation gray scale (100% of the second compensation gray scale-75% of the second compensation gray scale) × (130% -100%) + 100% of the second compensation gray scale
It should be noted that, in the embodiment of the present application, a fifth compensation gray scale is directly calculated by using different difference methods; and further determining the optimization degree of the fifth compensation gray scale according to the fifth compensation gray scale. That is, 130% of the above formula is calculated after determining the specific size of the fifth compensation gray scale.
In the embodiment of the present application, for the same third compensation gray scale and the fourth compensation gray scale, a plurality of different fifth compensation gray scales can be calculated by using a plurality of interpolation methods including, but not limited to, cubic interpolation, newton interpolation, and the like. That is, for the same third compensation gray scale and the same fourth compensation gray scale, there are a plurality of actually corresponding fifth compensation gray scales and a plurality of corresponding sixth compensation gray scales. However, only one of the fifth compensation gray scale and the sixth compensation gray scale has the best display effect.
As shown in fig. 4, a schematic flowchart of an embodiment of determining a sixth compensation gray scale provided by the present application may include:
41. and determining first brightness corresponding to the fifth compensation gray scale under the un-optimized front viewing angle and second brightness corresponding to the initial gray scale under the un-optimized front viewing angle.
42. And determining third brightness corresponding to the sixth compensation gray scale according to the first brightness and the second brightness.
43. And determining and optimizing the size of a sixth compensation gray scale of the display panel picture according to the third brightness.
Specifically, in the embodiment of the present application, the picture corresponding to the fifth compensation gray scale and the sixth compensation gray scale after compensation optimization needs to be the same as the picture corresponding to the initial gray scale before compensation optimization; among them, the brightness is mainly the same. I.e. the brightness of the picture before and after the compensation optimization does not change.
Therefore, in the embodiment of the present application, the first brightness corresponding to the gray scale value of the fifth compensation gray scale and the second brightness corresponding to the initial gray scale at the un-optimized front viewing angle can be obtained. The brightness corresponding to different gray scales can be directly measured, namely the first brightness and the second brightness can be directly obtained.
After the first brightness and the second brightness are determined, the third brightness may be determined first, and then the sixth compensation gray scale corresponding to the third brightness may be determined.
Specifically, a difference between a double value of the second luminance and the first luminance may be calculated to obtain a third luminance corresponding to the sixth compensation gray scale. And directly determining the gray scale value of the sixth compensation gray scale corresponding to the third brightness according to the measured gray scale-brightness relation. Of course, the third brightness is also the brightness value corresponding to the un-optimized front elevation angle.
In the embodiment of the present application, since the initial one gray scale is optimized to become two compensation gray scales, the brightness corresponding to the initial gray scale should be the average value of the brightness corresponding to the two optimized compensation gray scales. The brightness which is twice of the brightness corresponding to the initial gray scale is the sum of the brightness corresponding to the optimized fifth compensation gray scale and the brightness corresponding to the sixth compensation gray scale.
In one embodiment, taking the initial gray level 128 as an example, the luminance of the sixth compensation gray level is 2 × the luminance of the initial gray level 128 — the luminance of the fifth compensation gray level.
The sixth compensation gray scale corresponding to each fifth compensation gray scale can be calculated by the method. For the same third compensation gray scale and the same fourth compensation gray scale, a plurality of fifth compensation gray scales are obtained by interpolation by using different interpolation methods, so that a plurality of sixth compensation gray scales are also provided. And determining a target fifth compensation gray scale with an optimal picture and a corresponding target sixth compensation gray scale from the plurality of fifth compensation gray scales.
In the embodiment of the present application, a plurality of sets of the fifth compensation gray scale and the sixth compensation gray scale may be input into the display panel, and other picture parameters of the display panel are compared to determine the final target fifth compensation gray scale and the final target sixth compensation gray scale.
It should be noted that, in the embodiment of the present application, for a plurality of gray scales in the gray scale range corresponding to the display panel, the plurality of gray scales after being optimized correspond to a fifth compensation gray scale and a sixth compensation gray scale, and the fifth compensation gray scale and the sixth compensation gray scale correspond to each other. The whole trend of the fifth compensation gray scale corresponding to each initial gray scale is increased along with the increase of the initial gray scale; similarly, the overall trend of the sixth compensation gray scale corresponding to each initial gray scale is increased along with the increase of the initial gray scale. Namely, the compensation gray scale corresponding to the smaller initial gray scale is less than or equal to the compensation gray scale corresponding to the larger initial gray scale. Of course, this is for the same kind of compensation gray scale, for example, all the compensation gray scales are the fifth compensation gray scale, or all the compensation gray scales are the sixth compensation gray scale.
In one embodiment, the gray scale value of the fifth compensation gray scale corresponding to the initial gray scale 128 is smaller than or equal to the gray scale value of the fifth compensation gray scale corresponding to the initial gray scale 129. The magnitude of the sixth compensation gray scale value corresponding to the initial gray scale 128 is less than or equal to the magnitude of the sixth compensation value corresponding to the initial gray scale 129.
