[0050] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0051] According to an embodiment of the present application, a display screen calibration method is provided. Optionally, in the embodiments of the present application, the display screen calibration method can be applied in a hardware environment composed of a terminal 101 and a server 102 as shown in FIG. 1. As shown in FIG. 1, the server 102 is connected with the terminal 101 through a network, which can be used to provide services (such as application services, etc.) for the terminal or a client installed on the terminal, and a database can be set on the server or independently of the server, which is used to provide data storage services for the server 102. The network includes but is not limited to a wide area network, a metropolitan area network or a local area network, and the terminal 101 is not limited to a PC, a mobile phone, a tablet computer, etc. Figure 1 Figure 1 The display screen calibration method of the embodiments of the present application can be executed by the server 102, or by the terminal 101, or by both the server 102 and the terminal 101. Wherein, the terminal 101 executes the display screen calibration method of the embodiments of the present application, or the client installed thereon executes the display screen calibration method of the embodiments of the present application.

[0052] The display screen calibration method of the embodiments of the present application can be executed by the server 102, or by the terminal 101, or by both the server 102 and the terminal 101. Wherein, the terminal 101 executes the display screen calibration method of the embodiments of the present application, or the client installed thereon executes the display screen calibration method of the embodiments of the present application.

[0053] ​Taking a calibration method of a display screen executed by a terminal as an example, Figure 2 is a flowchart of an optional calibration method of a display screen according to an embodiment of the present application, as shown in the figure, the flow of the method can include the following steps: Figure 2

[0054] Step 201, determine the burn-in area to be calibrated.

[0055] In some embodiments, the determination of the burn-in area can be selected by the user when observing that there is a burn-in on the display screen, or the system can automatically identify that there is a burn-in on the display screen according to the current display screen, and then determine the burn-in area.

[0056] It can be understood that if the user determines the burn-in area, the terminal can be configured with a corresponding control. The user finds the control on the terminal and triggers it, so that the terminal enters an interface for the user to select the burn-in area, and then the user selects the burn-in area from the interface.

[0057] In an optional embodiment, determining the burn-in area to be calibrated comprises:

[0058] Obtaining the initial area selected by the user on the display interface;

[0059] Determine the icon including the initial area;

[0060] Determine the area corresponding to the icon as the burn-in area.

[0061] In some embodiments, after the user uses for a period of time and finds that there is a burn-in problem, the system provides a user automatic adjustment and calibration function, and the user manually checks the outline of the burn-in area to achieve rough selection of the burn-in area outline. The system determines the icon at the position of the initial area selected by the user according to the position information of the initial area, and since each icon has its own display area, the burn-in area can be determined according to the area corresponding to the icon.

[0062] Further, the system also provides increase and decrease buttons of row and column pixels, which can allow the user to adjust the check at will in pixel units to obtain the burn-in area.

[0063] It can be understood that when there are multiple icons including the initial area, the burn-in area is the sum of the areas corresponding to the multiple icons.

[0064] Generally, burn-in is caused by displaying a fixed screen for a long time, therefore, the system can automatically identify the pixel area information of the fixed screen and automatically check the area.

[0065] Step 202, display a gray scale screen under different colors, the gray scale screen includes the burn-in area. ​

[0066] In some embodiments, the gray scale picture can be a solid color image including part of the non-burn-in area in addition to the burn-in area, so that the user can adjust the color of the burn-in area based on the color of the non-burn-in area.

[0067] In an optional embodiment, displaying the gray scale pictures in different colors includes:

[0068] Obtaining a preset calibration level;

[0069] Generating the gray scale pictures of each color channel of RGB according to the calibration level.

[0070] In some embodiments, the preset calibration level can be set according to the color display accuracy of the display picture. For example, when the product is shipped, N gray scales are configured for each color channel according to the RGB color mode, so that each of the three color channels of red, green and blue displays N solid color pictures with different color levels. For example, two gray scales are initially set for each of red, green and blue, so that two solid color pictures are obtained for each of the red, green and blue color channels, and a total of six solid color pictures are obtained.

[0071] Step 203, obtaining the gray scale adjustment value of the user for the burn-in area in the gray scale picture.

[0072] In some embodiments, after the gray scale pictures in different colors are displayed, the user can determine the color difference between the burn-in area and the non-burn-in area through the displayed gray scale pictures, and then adjust the gray scale value of the burn-in area on the display screen to obtain the gray scale adjustment value.

[0073] In an optional embodiment, obtaining the gray scale adjustment value of the user for the burn-in area in the gray scale picture includes:

[0074] Determining a target gray scale picture for the current adjustment, the target gray scale picture being one or more of the plurality of gray scale pictures;

[0075] Displaying a gray scale value adjustment object of the target gray scale picture, the gray scale value adjustment object being used to adjust the gray scale value of the burn-in area;

[0076] Obtaining the gray scale adjustment value of the user for the adjustment of the gray scale value adjustment object.

[0077] In some embodiments, there are usually multiple gray scale pictures, and therefore each gray scale picture needs to be adjusted. Therefore, the user can determine a target gray scale picture by clicking on a gray scale picture, display the gray scale value adjustment object of the target gray scale picture, trigger the gray scale value adjustment object by the user, and realize the adjustment of the gray scale value to obtain the gray scale adjustment value.

[0078] In some embodiments, the gray scale adjustment value can be the adjustment amount of the gray scale value, or the gray scale value obtained after the adjustment.

[0079] It can be understood that the adjustment of the gray scale picture can be that one gray scale picture is adjusted and then another gray scale picture is adjusted, or that multiple gray scale pictures are adjusted at the same time.

[0080] The gray scale value adjustment object can be, but is not limited to, a gray scale value adjustment button or a gray scale value adjustment progress bar. The user can increase or decrease the gray scale value of the burn-in area by clicking the gray scale value adjustment button or dragging the gray scale value adjustment progress bar.

[0081] When the position area is selected, the compensation adjustment mode is entered. In the RGB pure color picture, for example, 256 gray scales are divided into N parts (the smaller N is, the more accurate the gray scale control is), and the gray scale brightness is adjusted respectively, for example, N = 8, that is, 32 gray scales are adjusted. In each gray scale, the user can adjust to an acceptable range.

[0082] In step 204, the initial gray scale value is calibrated based on the gray scale adjustment value to obtain a calibrated gray scale value. The initial gray scale value is a factory gray scale value or a gray scale value after the last calibration.

[0083] In some embodiments, after obtaining the gray scale adjustment value, the initial gray scale value can be calibrated by the gray scale adjustment value, so that when the display screen displays according to the calibrated gray scale value, the burn-in can be eliminated.

[0084] Further, in the case where the gray scale adjustment value is an adjustment amount of the gray scale value, the gray scale adjustment value can be added to the initial gray scale value to obtain the calibrated gray scale value. The gray scale adjustment value usually has a positive and negative value. In the case of increasing the gray scale value, the gray scale adjustment value is positive. In the case of decreasing the gray scale value, the gray scale adjustment value is negative.

[0085] In the case where the gray scale adjustment value is an adjusted gray scale value, the gray scale adjustment value can be directly replaced by the corresponding initial gray scale value.

[0086] The calibration of the initial gray scale value refers to the calibration of the initial gray scale value of the burn-in area.

[0087] The initial gray scale value can be a factory gray scale value, that is, a factory de_mura data table, or a gray scale value obtained after the last calibration.

[0088] In an optional embodiment, in order not to affect other applications when calibrating the display screen, before displaying the gray scale picture under different colors, the method further includes determining that the display screen enters a burn-in calibration mode.

[0089] After the initial gray scale value is calibrated based on the gray scale adjustment value to obtain a calibrated gray scale value, the method further includes determining that the display screen exits the burn-in calibration mode.

[0090] After the burn-in area is determined, the terminal can determine that the calibration of the display screen can be performed at present, so as to enter the burn-in calibration mode, so that the subsequent calibration process is performed in the mode and does not affect other application services. After the gray scale value has been calibrated and the burn-in phenomenon has been eliminated, the burn-in calibration mode can be exited, so that the display screen can provide display services according to normal conditions.

[0091] Step 205: displaying a picture of the display screen according to the calibrated gray scale value.

[0092] In some embodiments, the picture of the display screen is displayed by using the calibrated gray scale value, so that the gray scale value of the burn-in area is compensated, and the subsequent displayed picture eliminates the burn-in phenomenon.

[0093] In one specific embodiment, referring to Figure 3 When the user finds the burn-in problem after using the system for a period of time, the system provides a user automatic adjustment and calibration function, and the user manually selects the outline of the burn-in area (coarse selection). Generally, the burn-in is caused by displaying a fixed picture for a long time. At this time, the system can automatically identify the pixel area information of the fixed picture and automatically select the area (solid color). The system also provides row and column increase and decrease buttons, so that the user can randomly adjust and select the area (fine selection, for mixed color pictures). When the position area is selected, the adjustment and compensation mode is entered. In the R / G / B solid color picture, 8 bits are taken as an example. 256 gray scales are divided by N (the smaller N is, the more accurate the gray scale control is). The gray scale brightness is adjusted respectively. For example, N = 8, that is, 32 gray scales are adjusted. In each gray scale, the user can adjust to an acceptable range, and the adjusted data is saved in the corresponding storage table. Finally, the user's adjusted data is fed back to the system. The system automatically combines the data in the de_mura data table adjusted at the time of factory shipment with the data in the storage table for weighted processing, so that the compensation debugging is completed. The originally burned-in display screen is given a new life.

[0094] Specifically, referring to Figure 4 The burn-in area is taken as an example Figure 4 Taking the heart-shaped area of the interface in (a) as an example, after the user observes the occurrence of the burn-in, the user enters the burn-in icon interface. The user selects the icon to be debugged according to the burn-in position, and takes the icon as the burn-in calibration area; as shown in Figure 4 As shown in (b), the selected burn-in calibration area can be determined to be selected by changing the color (from white to black).

[0095] After selecting the burn-in calibration area, enter the calibration mode, enter the R / G / B pure color test screen, each pure color screen can be divided into N gray scales, as shown in Figure 4 (c), the test screen of red, green and blue can be set to two gray scale screens with different gray scales, and under each gray scale screen, the user can independently adjust the gray scale brightness of the selected area by Figure 4 (d) shown in the gray scale value adjustment control, that is, the user can independently adjust the gray scale value of the selected area by adding or subtracting the gray scale value of the selected area until the difference between each gray scale screen burn-in calibration area and the entire screen color is small, as shown in Figure 4 (e).

[0096] After adjustment, the gray scale value adjustment value of the burn-in calibration area is different from that of other areas, and the once gray scale value adjustment value of other areas remains 0, Figure 4 (f), the color deep area is the burn-in calibration area, and since the gray scale value adjustment value of the burn-in calibration area is adjusted, it can be saved to the storage table corresponding to the color. In subsequent display screens, the saved data and the original de-mura data (such as Figure 4 (g) shown) are weighted to obtain compensation effect, thereby eliminating the burn-in phenomenon, as shown in Figure 4 (h) shown.

[0097] The calibration method of the display screen of the present application can enable the user to adjust the gray scale value of the burn-in area after the display screen is shipped, greatly improving the service life of the display screen, solving the problem that de-mura needs to be debugged with professional equipment and cannot be changed after the display screen is produced by the display screen manufacturer. When the user end has a burn-in problem, it does not need to be solved by replacing the screen, and the user can independently adjust, improve or even eliminate the burn-in phenomenon, so that the originally scrapped display screen can be replaced with a new one. In addition, without additional hardware cost, only software algorithm can be used to achieve the effect, which has high feasibility.
