First, in an embodiment of the present application, a method for optimizing a frame of a display panel is provided, where the display panel includes a plurality of pixels.
The method comprises the following steps: taking any pixel in the plurality of pixels as a target pixel, and determining the initial gray scale displayed before the target pixel is not optimized; performing first compensation optimization on the initial gray level to obtain a first compensation gray level and a second compensation gray level, wherein the first compensation gray level is larger than the initial gray level, and the second compensation gray level is smaller than the initial gray level; 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 of the optimized display panel picture according to the third compensation gray scale and the fourth compensation gray scale; determining a sixth compensation gray level of the optimized display panel picture according to the fifth compensation gray level and the initial gray level; 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 flowchart illustrating an embodiment of a method for optimizing a display panel according to an embodiment of the present application. 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 application, in order to solve the problem of the viewing angle 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 taken as a target pixel, and an initial gray scale displayed before the target pixel is not optimized may be determined; performing first compensation optimization on the initial gray scale to obtain initial first compensation gray scale and second compensation gray scale; and compensating the display panel by using the first compensation gray scale and the second compensation gray scale.
However, in the display panels of different types 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, this may cause other display problems for different types of display panels, and it is still impossible to achieve a better display for each display panel. It is therefore necessary to continue adjusting the compensation gray level.
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 becomes the first compensation gray level 150 (Highcode) and the second compensation gray level 50 (Lowcode). In general, the gray scale value of the first compensation gray scale is larger than the gray scale value corresponding to the initial gray scale, and the gray scale value corresponding to the second compensation gray scale is smaller 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 level and the second compensation gray level are two compensation gray levels corresponding to the initial gray level of the target pixel in the prior art, but for different display panels, the same first compensation gray level and second compensation gray level are used to compensate the picture, which causes other display problems, so that the first compensation gray level and the second compensation gray level 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 application, the third compensation gray scale of the first optimization degree and the fourth compensation gray scale of the second optimization degree are mainly calculated.
24. And obtaining a fifth compensation gray level of the optimized display panel picture according to the third compensation gray level and the fourth compensation gray level.
The third compensation gray level and the fourth compensation gray level are actually obtained by optimizing the original second compensation gray level to different degrees. In this embodiment of the present application, after determining the third compensation gray level and the fourth compensation gray level, the fifth compensation gray level may be obtained by using the third compensation gray level and the fourth compensation gray level. The fifth compensation gray scale can be understood as: and obtaining the second compensation gray scale after performing other optimization degrees which are different from the first optimization degree and the second optimization degree. When the fifth compensation gray scale is obtained through calculation, the third compensation gray scale and the fourth compensation gray scale are utilized to calculate instead of directly calculating the second compensation gray scale, so that the calculation accuracy can be effectively improved, and the phenomenon that the second compensation gray scale with larger original error still has larger error after calculation and influences the picture display is avoided.
25. And determining a sixth compensation gray level of the optimized display panel picture according to the fifth compensation gray level and the initial gray level.
Since in the embodiment of the present application, one initial gray level is optimized, a set of two associated compensation gray levels (i.e., highcode and Lowcode) are usually obtained, and the gray levels of the two compensation gray levels are different. However, in the foregoing embodiment, only the fifth compensation gray scale is obtained, and therefore, the sixth compensation gray scale associated with the fifth compensation gray scale is also required to be obtained; the fifth compensation gray scale and the sixth compensation gray scale are all gray scales required for optimizing the display panel.
In this embodiment of the present application, the fifth compensation gray level and the initial gray level may be used to determine, from the two final compensation gray levels corresponding to the initial gray level after compensation optimization, another compensation gray level other than the fifth compensation gray level. The fifth compensation gray scale and the initial gray scale are two compensation gray scales obtained by optimizing the initial gray scale by using the display panel picture optimizing 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, first compensation gray scales and second compensation gray scales corresponding to the first compensation optimization are acquired, and the first compensation gray scales are larger than the second compensation gray scales; then calculating a third compensation gray scale and a fourth compensation gray scale under different optimization degrees by using the second compensation gray scale with smaller values; and then 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 further calculating a sixth compensation gray scale corresponding to the theory after the initial gray scale optimization according to the first brightness corresponding to the fifth compensation gray scale and the second brightness corresponding to the initial gray scale before the optimization so as to optimize the picture of the display panel according to the fifth compensation gray scale and the sixth compensation gray scale. According to the method and the device for optimizing the images, multiple times of optimization is carried out, the optimal image optimization degree corresponding to each display panel can be determined, the image optimization precision is improved, and the difference of image optimization of different display panels is achieved.
As shown in fig. 3, an embodiment of calculating the third compensation gray level and the fourth compensation gray level according to the embodiments of the present application is shown, which may include:
31. And calculating a third compensation gray scale corresponding to the first optimization degree according to the preset first adjustment ratio and the second compensation gray scale.
32. And calculating 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: and the ratio of the first difference value between the gray level obtained after the second compensation gray level optimization and the initial gray level to the second difference value between the gray level obtained before the second compensation gray level optimization and the initial gray level.
Taking the initial gray level 128, the first compensation gray level 150 and the second compensation gray level 50 as examples, the second difference between the second compensation gray level 50 and the initial gray level 128 is 128-50=78; if the first optimization degree (i.e., the first adjustment ratio) is 100%, it is indicated that the difference between the value of the third compensation gray level obtained by optimizing the second compensation gray level 50 and the initial gray level 128 is 78% of the percentage, i.e., the third compensation gray level is 50.
If the second optimization degree (i.e. the second adjustment ratio) is 75%, the fourth compensation gray scale is: 128- (128-50) 0.75=69.5, i.e. the ratio between the first difference 58.5 between the fourth compensation gray level and the initial gray level and the second difference 70 between the second compensation gray level and the initial gray level is 70%.
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 compensated gray level after optimization and the initial gray level is explained.
In embodiments 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.
Of course, in the embodiment of the present application, if the third compensation gray level and the fourth compensation gray level are not integers, the third compensation gray level and the fourth compensation gray level are rounded up to obtain the rounded third compensation gray level and fourth compensation gray level.
And after the third compensation gray level and the fourth compensation gray level are determined, a fifth compensation gray level can be further calculated. Specifically, the third compensation gray scale and the fourth compensation gray scale may be interpolated by a preset interpolation method to obtain the 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 to other optimization degrees, but the actual calculation is not obtained by using the second compensation gray scale, but by using the third compensation gray scale and the fourth compensation gray scale.
In embodiments of the present application, the degree of optimization (or adjustment ratio) may be greater than a percentage. In one embodiment, the fifth compensation gray level corresponding to 130% of the optimization degree compared to the second compensation gray level may be obtained by using linear interpolation calculation. The method comprises the following steps:
fifth compensation gray level= (100% second compensation gray level-75% second compensation gray level) + (130% -100%) +100% second compensation gray level
It should be noted that, in the embodiment of the present application, the 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 formulas are 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 level and fourth compensation gray level, a plurality of different fifth compensation gray levels may be calculated by using a plurality of interpolation methods including, but not limited to, cubic interpolation, newton interpolation, and the like. That is, there are a plurality of fifth compensation gray scales actually corresponding to the same third compensation gray scale and fourth compensation gray scale, and a plurality of sixth compensation gray scales corresponding to the same third compensation gray scale and fourth compensation gray scale. 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 flowchart of an embodiment of determining a sixth compensation gray level according to the present application may include:
41. and determining the first brightness corresponding to the fifth compensation gray scale under the non-optimized front view angle and the second brightness corresponding to the initial gray scale under the non-optimized front view angle.
42. And determining a 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 the sixth compensation gray scale of the display panel picture according to the third brightness.
Specifically, in the embodiment of the present application, the frames corresponding to the fifth compensation gray level and the sixth compensation gray level after compensation optimization need to be the same as the frames corresponding to the initial gray level before compensation optimization; wherein the brightness is mainly the same. I.e. the brightness of the picture before and after compensation optimization will 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 under the front view angle without optimization 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 luminance and the second luminance are determined, the third luminance may be determined first, and then a sixth compensation gray scale corresponding to the third luminance may be determined.
Specifically, a difference between 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 relationship. Of course, the third luminance is also a luminance value corresponding to the non-optimized front view angle.
In the embodiment of the present application, since the initial gray level is optimized and then becomes two compensation gray levels, the brightness corresponding to the initial gray level should be the average value of the brightness corresponding to the two optimized compensation gray levels. The brightness corresponding to the initial gray level is twice the sum of the brightness corresponding to the optimized fifth compensation gray level and the brightness corresponding to the sixth compensation gray level.
In one embodiment, taking the initial gray level 128 as an example, the brightness=2 of the sixth compensation gray level at this time is the brightness of the initial gray level 128-the brightness of the fifth compensation gray level.
The sixth compensation gray level corresponding to each fifth compensation gray level can be calculated by using the method. The same third compensation gray scale and the same fourth compensation gray scale are interpolated by different interpolation methods to obtain a plurality of fifth compensation gray scales, so that the sixth compensation gray scales are also a plurality of. It is also necessary to determine a target fifth compensation gray level of the frame optimum among the plurality of fifth compensation gray levels, and a corresponding target sixth compensation gray level.
In the embodiment of the present application, a plurality of sets of fifth compensation gray levels-sixth compensation gray levels 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 level and the target sixth compensation gray level.
In the embodiment of the present application, the plurality of gray scales in the gray scale range corresponding to the display panel correspond to a fifth compensation gray scale and a sixth compensation gray scale after the plurality of gray scale compensation is optimized, and the fifth compensation gray scale and the sixth compensation gray scale correspond to each other. The overall trend of the fifth compensation gray level corresponding to each initial gray level is increased along with the increase of the initial gray level; similarly, the overall trend of the sixth compensation gray level corresponding to each initial gray level increases with the increase of the initial gray level. Namely, the compensation gray level corresponding to the smaller initial gray level is smaller than or equal to the compensation gray level corresponding to the larger initial gray level. Of course, for the same type of compensation gray level, for example, the fifth compensation gray level or the sixth compensation gray level.
In one embodiment, the magnitude of the gray level value of the fifth compensation gray level corresponding to the initial gray level 128 is less than or equal to the magnitude of the fifth compensation gray level value corresponding to the initial gray level 129. And the magnitude of the sixth compensation gray-scale value corresponding to the initial gray-scale 128 is smaller than or equal to the magnitude of the sixth compensation value corresponding to the initial gray-scale 129.
In order to better implement the display panel frame optimization method in the embodiment of the present application, on the basis of the display panel frame optimization method, a display panel frame optimization device is further provided in the embodiment of the present application, as shown in fig. 5, fig. 5 is a schematic structural diagram of an embodiment of the display panel frame optimization device provided in the embodiment of the present application, where the display panel frame optimization device includes:
