Detailed Description
As described in the background art, the related art display panel has a problem of a splash screen when switching refresh frequencies, and the inventor has found that the reason for this problem is mainly that, in the case where a plurality of refresh frequencies share a group of gamma curves, the lower the refresh rate, the lower the brightness of the display panel, as shown in fig. 1, the brightness difference of the display panel exists at different refresh rates, resulting in the display panel having a splash screen at the time of switching the refresh rate.
Aiming at the technical problems, considering that the brightness of the display panel is affected by gray scale, the embodiment of the application provides a display control method, a gamma curve is obtained by debugging at one refresh frequency of the display panel, the gamma curve is used for improving the brightness, gray scale compression of different degrees is carried out for different refresh frequencies during display, and the brightness is reduced, so that the brightness of the display panel at different refresh frequencies can reach the required normal brightness, and the problem of screen flashing when the refresh frequency is switched is avoided.
In order to make the above objects, features and advantages of the embodiments of the present application more comprehensible, the following description will make the technical solutions of the embodiments of the present application clear and complete with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, based on the embodiments herein, which are within the scope of the protection of the present application, will be within the purview of one of ordinary skill in the art without the exercise of inventive faculty.
Fig. 2 is a flow chart of a display control method according to an embodiment of the present application. The method is implemented by a display device, which may be implemented by software and/or hardware, and the device may be a chip, for example. As shown in fig. 2, the method includes:
s201, acquiring a first gamma curve, wherein the maximum brightness value corresponding to the maximum gray scale value in the first gamma curve is larger than the target brightness value, and the first gamma curve is obtained by gamma debugging at a first refresh frequency of the display panel.
The first gamma curve in this step is a gamma curve common to a plurality of groups of refresh frequencies of the display panel, and by way of example, the refresh frequencies may be 120HZ, 60HZ, 30HZ, etc., which is not limited by the embodiments of the present disclosure. The first refresh rate may be a main refresh rate of the display panel, i.e. a refresh rate of the display panel that is more frequently used. For example, if the main refresh frequency of the display panel is 120HZ, the first gamma curve may be obtained by gamma debugging at 120 HZ. For example, if the main refresh frequency of the display panel is 60HZ, the first gamma curve may be obtained by performing gamma adjustment at 60HZ, and specific steps of gamma adjustment may be referred to the related art, which is not described herein. The gamma debugging process of the first gamma curve is performed in advance.
The target brightness value is a brightness value that the display panel is expected to achieve at the maximum gray scale value (255), and in practical applications, the target brightness value may be determined according to a requirement set by a device manufacturer using the display panel. For example, the target luminance value is 511, that is, the luminance value of the display panel at 255 gray scales is desired to be 511, and the maximum luminance value corresponding to 255 gray scales in the first gamma curve is greater than 511, for example, the maximum luminance value corresponding to 255 gray scales in the first gamma curve is 590, that is, according to the first gamma curve, the luminance of the display panel is higher than the luminance value actually required to be displayed at the first display frequency.
S202, determining a second refreshing frequency corresponding to a frame picture to be displayed and a maximum gray scale compression value corresponding to the second refreshing frequency, wherein when a first gamma curve is adopted at the second refreshing frequency, a brightness value corresponding to the maximum gray scale compression value is a target brightness value.
When the frame picture to be displayed is displayed, a second refresh frequency corresponding to the frame picture to be displayed is firstly determined, the second refresh frequency can be the same as or different from the first refresh frequency, and the second refresh frequency can be any one of a plurality of groups of refresh frequencies of the display panel. Because the brightness of the display panel is improved by the first gamma curve, when in actual display, gray scales are required to be compressed according to the actual second refresh frequency, so that the corresponding brightness reaches the required normal brightness, and therefore, the brightness is reduced by adopting a gray scale compression mode in the embodiment of the application. And determining a corresponding maximum gray scale compression value under the second refreshing frequency, wherein when the first gamma curve is adopted under the second refreshing frequency, the brightness value corresponding to the maximum gray scale compression value is a target brightness value.
For example, the first refresh frequency is 120HZ, the maximum brightness value corresponding to the 255 gray levels in the first gamma curve is 590, the target brightness value is 511, and the second refresh frequency is 60HZ, and the maximum gray level compression value corresponding to the second refresh frequency is 241, that is, when the first gamma curve is adopted at the refresh frequency of 60HZ, the brightness value of the display panel is 511 when the gray level value is 241. Assuming that the second refresh frequency is 120HZ, the maximum gray-scale compression value corresponding to the second refresh frequency is 239, that is, the luminance value of the display panel is 511 when the gray-scale value is 239 when the first gamma curve is adopted at the refresh frequency of 120 HZ.
S203, displaying the frame picture to be displayed according to the first gamma curve and the maximum gray scale compression value.
The brightness of the first gamma curve is compressed by using the maximum gray scale compression value at the second refresh frequency, for example, when the second refresh frequency is 60HZ, the 255 gray scales are compressed to 241 gray scales, so as to reach the target brightness value 511, and when the second refresh frequency is 120HZ, the 255 gray scales are compressed to 239 gray scales, so as to reach the target brightness value 511. And when the frame picture to be displayed is displayed, the gray scale to be displayed is correspondingly compressed according to the gray scale to be displayed corresponding to the frame picture to be displayed and the maximum gray scale compression value under the second refreshing frequency, and the brightness corresponding to the gray scale to be displayed is reduced, so that the frame picture to be displayed can display the normal brightness under the gray scale to be displayed.
In the display control method provided by the embodiment of the invention, different refreshing frequencies share the first gamma curve, wherein the first gamma curve is obtained by debugging at the first refreshing frequency, the first gamma curve is used for improving the brightness value to be higher than the target brightness value, and when in actual display, the gray scale to be displayed is compressed by utilizing the gray scale compression mode according to the second refreshing frequency of the frame picture to be displayed and the corresponding maximum gray scale compression value, so that the frame picture to be displayed at the second refreshing frequency displays the normal brightness of the gray scale to be displayed, and therefore, under the different second refreshing frequencies, the brightness of the frame picture to be displayed is not different, and the phenomenon that the display panel flashes when the refreshing frequencies are switched under the condition that different refreshing frequencies share one group of gamma curves is avoided.
On the basis of the above embodiments, how to determine the first gamma curve and how to determine the maximum gray scale compression value corresponding to the second refresh frequency will be described.
Under the first refreshing frequency, determining a target brightness value as a brightness value corresponding to a first maximum gray scale compression value, and determining a maximum brightness value corresponding to the maximum gray scale value according to the target brightness value and the first maximum gray scale compression value; and gamma debugging is carried out on the display panel according to the maximum brightness value corresponding to the maximum gray level value, so that a first gamma curve is obtained.
In order to enable the first gamma curve to boost the brightness, the target brightness value is determined to be the brightness value corresponding to the first maximum gray scale compression value at the first refresh frequency, and the first maximum gray scale compression value is the maximum gray scale compression value corresponding to the first refresh frequency. For example, the first refresh frequency is 120HZ, the maximum gray-scale compression value corresponding to the first refresh frequency is 239, the target brightness value 511 is determined as the brightness value corresponding to the gray-scale value 239, then the maximum brightness value corresponding to the maximum gray-scale value 255 is calculated as 590, for example, the maximum brightness value corresponding to the maximum gray-scale value 255 is calculated as 590 by using a standard formula when gamma is 2.2, and gamma debugging is performed with the brightness value 590 as the brightness of 255 gray-scales, thereby obtaining the first gamma curve.
Optionally, at the second refresh frequency, according to the first gamma curve, gradually reducing the gray scale value from the maximum gray scale value, controlling the display panel to display, and determining the gray scale value when the brightness value displayed by the display panel is the target brightness value as the maximum gray scale compression value.
In order to determine the maximum gray scale compression value corresponding to the second refresh frequency, the display panel may be controlled to display according to the first gamma curve at the second refresh frequency, when the maximum gray scale value is larger than the target brightness value, the gray scale value is gradually reduced until the brightness value displayed by the display panel is the target brightness value, and when the gray scale value is the maximum gray scale compression value, it may be determined that the maximum gray scale value needs to be compressed to the maximum gray scale compression value at the second refresh frequency. For example, when the second refresh frequency is 60HZ, the display panel is controlled to display according to the first gamma curve, and when the gray scale value is 241, the luminance value displayed on the display panel is the target luminance value 511, and therefore, the maximum gray scale compression value corresponding to the second refresh frequency is determined to be 241.
When a frame picture to be displayed is displayed, determining the gray scale to be displayed of the frame picture to be displayed; determining a brightness value to be displayed corresponding to the gray scale to be displayed according to the first gamma curve and the maximum gray scale compression value; and displaying the frame picture to be displayed according to the brightness value to be displayed.
Because the first gamma curve improves the brightness, when the picture to be displayed is displayed at the second refresh frequency, the gray scale to be displayed needs to be compressed according to the second refresh frequency to obtain the corresponding brightness value. Specifically, according to the maximum gray scale compression value corresponding to the first gamma curve and the second refreshing frequency, determining a brightness value to be displayed corresponding to the gray scale to be displayed, wherein the brightness value to be displayed is the brightness value corresponding to the gray scale to be displayed after being compressed according to the maximum gray scale compression value, so that the brightness of the frame picture to be displayed is normal.
Optionally, determining a ratio between the maximum gray scale compression value and the maximum gray scale value corresponding to the second refresh frequency; and determining the brightness value to be displayed according to the first gamma curve, the gray scale to be displayed and the proportion. The ratio between the maximum gray scale compression value and the maximum gray scale value corresponding to the second refreshing frequency is the compression ratio of the gray scale under the second refreshing frequency, the gray scale to be displayed is compressed according to the compression ratio, and then the brightness value to be displayed is determined according to the first gamma curve, and the brightness value to be displayed is the normal brightness value of the gray scale to be displayed under the second refreshing frequency.
In the method of the embodiment of the application, the brightness value is improved through the first gamma curve, the brightness is reduced to normal brightness through the gray scale compression mode, and when the second refreshing frequency is different, the corresponding maximum gray scale compression value is different, namely the compression ratio of the brightness of the first gamma curve is different, so that the same brightness corresponding to the same gray scale value can be ensured under different second refreshing frequencies, and the occurrence of the screen flashing during the switching of the refreshing frequencies is avoided.
The method of the embodiment of the application can also carry out the debug of demura compensation on the basis of the gray scale compression, and carry out the compensation during display. This will be described below.
Controlling the display panel to display according to the first gamma curve and the first maximum gray scale compression value under the first refresh frequency, and shooting the display panel; and determining a pixel gray-scale compensation value of the display panel according to the pixel brightness difference in the photographed image.
And under the first refreshing frequency, compressing the gray scale according to a first maximum gray scale compression value corresponding to the first refreshing frequency, namely reducing the brightness, controlling the display panel to display, shooting the display panel, and determining a pixel gray scale compensation value of the display panel according to the pixel brightness difference in the shot image. The display panel compresses the brightness according to the first gamma curve and then displays the compressed brightness, so that the compensation range of the pixel gray-scale compensation value is more flexible when the pixel gray-scale compensation value is determined, the gray scale can be reduced or increased, the compensation effect can be achieved on black spots of a white picture, and the better compensation effect is achieved.
On the basis of determining the pixel gray level compensation value of the display panel through the debugging of the method, corresponding compensation can be performed during display.
Determining target gray scale according to gray scale to be displayed and pixel gray scale compensation value of the frame picture to be displayed; determining a brightness value to be displayed corresponding to the target gray scale according to the first gamma curve and the maximum gray scale compression value; and displaying the frame picture to be displayed according to the brightness value to be displayed.
The target gray scale is a gray scale value obtained by compensating the gray scale to be displayed by adopting a pixel gray scale compensation value, and a brightness value to be displayed corresponding to the gray scale to be displayed is determined according to a maximum gray scale compression value corresponding to the first gamma curve and the second refreshing frequency, wherein the brightness value to be displayed is a brightness value corresponding to the target gray scale after the target gray scale is compressed according to the maximum gray scale compression value.
Optionally, determining a ratio between the maximum gray scale compression value and the maximum gray scale value corresponding to the second refresh frequency; and determining a brightness value to be displayed according to the first gamma curve, the target gray scale and the proportion. The ratio between the maximum gray scale compression value and the maximum gray scale value corresponding to the second refreshing frequency is the compression ratio of the gray scale under the second refreshing frequency, the target gray scale is compressed according to the compression ratio, and then the brightness value to be displayed is determined according to the first gamma curve, and the brightness value to be displayed is the normal brightness value corresponding to the target gray scale under the second refreshing frequency after being compressed. By compensating the brightness, the brightness difference between pixels of the display panel is avoided, and the display effect is optimized.
