Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In the absence of conflict, the following embodiments and their technical features can be combined with each other.

[0023] Figure 1 This is a flowchart illustrating the steps of a display module debugging method according to an embodiment of this application. Figure 1 As shown, the display module debugging method includes the following steps:

[0024] Step 101: Obtain the difference in brightness compensation values ​​of multiple first display modules at adjacent first test binding points.

[0025] Step 102: Perform a lighting test on the second display module based on at least one second test binding point to obtain a first correspondence between the second test binding point and the second brightness compensation value used to compensate when display data is written to the second display module, wherein the second display module is of the same type as the first display module, and the number of second test binding points is less than the number of first test binding points.

[0026] Step 103: Determine the correspondence between the lighting data and the brightness compensation values ​​of the second display module based on the first correspondence and the difference between multiple brightness compensation values.

[0027] Step 104: Write the correspondence between the illumination data and the brightness compensation value of the second display module into the registers included in the second display module, so that when the second display module displays the data to be displayed, it performs display compensation according to the correspondence between the illumination data and the brightness compensation value of the second display module.

[0028] During the production of display modules, gamma calibration is typically required. Gamma is an exponential curve used by the display module to adjust the color values ​​actually output to the display screen, thereby better adapting to the user's visual experience. In the current production process, each display module needs to be lit up multiple times, and the actual brightness of the display module needs to be obtained during the lighting process to determine the display compensation value under different lighting parameters, thus obtaining the gamma calibration result. However, in this process, the higher the calibration precision, the more lighting times are required, resulting in low calibration efficiency. To improve debugging efficiency, a small number of first display modules are selected for lighting tests during the debugging process to obtain the difference in brightness compensation values ​​of the first display modules at adjacent first test points. When debugging second display modules of the same type as the first display modules, only at least one second test point needs to be selected for debugging to obtain the first correspondence between the second test point and the second brightness compensation value used to compensate when display data is written to the second display module. Then, using the first test point and the difference value of the first display module during the lighting test, the correspondence between the lighting data and the brightness compensation value of the second display module is derived using the first correspondence. Finally, this correspondence is written into the registers included in the second display module to complete the debugging of the second display module.

[0029] For example, if there are 10,000 display modules of the same type, 50 of them are selected as the first display module, and 15 first test points are selected for lighting tests. These first test points include the second test point. After the lighting test, the difference in brightness compensation value between the first and second test points is Δ1; the difference between the second and third test points is Δ2, and so on, obtaining Δ1-Δ15. The remaining 9,550 display modules... As the second display module, one second test point is selected for lighting test, and this second test point is the same as one of the first test points. For example, if the first first test point is selected as the second test point, after the lighting test is completed, the obtained display compensation value is subtracted by Δ1 to obtain the brightness compensation value under the second test point. Subtracting Δ2 from the brightness compensation value under the second second test point gives the brightness compensation value under the third test point, and so on, to obtain 15 test points and the corresponding brightness compensation values ​​for 15 test points. Alternatively, if the 15th first test point is selected as the second test point, after the lighting test is completed, the obtained display compensation value is added to Δ1 to obtain the brightness compensation value under the 14th test point. The brightness compensation value under the 14th second test point is added to Δ2 to obtain the brightness compensation value under the 13th test point. And so on, 15 test points and their corresponding brightness compensation values ​​can be obtained. Thus, the correspondence between the lighting data and brightness compensation values ​​of the second display module can be derived.

[0030] After the correspondence between the lighting data and the brightness compensation value of the second display module is written into the registers included in the second display module, when the second display module receives the data to be displayed, it will obtain the corresponding brightness compensation value from the register according to the data to be displayed before writing the data to be displayed into the pixel circuit. Then, when the data to be displayed is written into the pixel circuit, compensation is made by the brightness compensation value, thereby ensuring that the brightness display is normal.

[0031] In this embodiment, by utilizing the difference in brightness compensation values ​​of the first display module under adjacent first test points, when debugging the second display module, a number of second test points less than the number of first test points can be selected for debugging, thereby improving the debugging efficiency of the second display module.

[0032] Specifically, Figure 2 This is a flowchart illustrating the steps of a method for determining the difference amount according to an embodiment of this application. Figure 2 As shown, the method for determining the compensation table includes the following steps:

[0033] Step 201: Control the first display module to light up according to multiple first test binding points, and obtain multiple first actual brightness values ​​when the first display module is lit up.

[0034] Step 202: Determine the difference in brightness compensation values ​​of multiple first display modules at adjacent first test points based on the target brightness corresponding to multiple first test points and multiple first actual brightness.

[0035] To determine the difference in brightness compensation values ​​of the first display module at adjacent first test points, it is necessary to obtain the first actual brightness of the first display module at different first test points. Therefore, firstly, the first display module is controlled to be lit according to the first first test point, and the first actual brightness after the first display module is lit is obtained. This operation is repeated to obtain multiple first actual brightnesses when the first display module is lit. At the same time, based on the first test points, the normal brightness of the normal display module at the first test points can be determined. This normal brightness is taken as the target brightness corresponding to the first test point. Then, based on the brightness difference between the first actual brightness and the target brightness of the first display module at the first test point, the compensation value of the first display module at the first test point is determined. Finally, based on the target brightness and the multiple first actual brightness corresponding to the multiple first test points, the difference in brightness compensation values ​​of the multiple first display modules at adjacent first test points is determined.

[0036] Specifically, the difference in brightness compensation values ​​of the first display module at adjacent first test points includes multiple sub-differences corresponding to compensation values ​​for different color channels. For example, it may include R (red) sub-difference, G (green) sub-difference, and B (blue) sub-difference. For instance, Δ1 includes ΔR1, ΔG1, and ΔB1, thereby improving the accuracy of display compensation performed by the second display module when displaying data to be displayed.

[0037] Specifically, the first test binding point includes: brightness level and grayscale. The grayscale values ​​included in the first test binding point include at least: 255, 239, 207, 143, 111, 79, 63, 47, 31, 23, 15, 11, 7, 3 and 1.

[0038] For example, the difference values ​​corresponding to adjacent test binding points of multiple first test binding points can be shown in Table 1:

[0039] Table 1

[0040]

[0041] Wherein, Step is used to characterize the compensation value, Step AA is used to characterize the brightness compensation value corresponding to the first display module at the first gray level (255 in the example in the table) under brightness level A, Delta is used to characterize the difference value, and Delta AAAB is used to characterize the difference value between Step AA and Step AB corresponding to adjacent gray levels.

[0042] Furthermore, it should be noted that because the display module exhibits lower brightness at low grayscale levels, and the compensation value required at low brightness is typically greater than that at high brightness, the values ​​of the first test points are spaced further apart at high grayscale levels and closer apart at low grayscale levels. Additionally, since the number of first display modules is relatively small, the number of first test points can be increased to improve debugging accuracy.

[0043] Specifically, the second test point is determined based on the first test point. The second test point is a subset of the first test points; that is, the first test point includes the second test point. Taking Table 1 as an example of the first test point, the grayscale values ​​included in the second test point can be selected from a subset of 255, 239, 207, 143, 111, 79, 63, 47, 31, 23, 15, 11, 7, 3, and 1. To improve the debugging efficiency of the second display module, only one grayscale value can be selected, but for ease of calculation, this value must be a boundary value, i.e., 255 or 1. Furthermore, to improve the debugging accuracy of the second display module, an additional grayscale value can be selected, choosing the median value of the first test point. For example, the grayscale values ​​included in the second test point can be 255 and 63.

[0044] Figure 3 This is a schematic diagram of a display module debugging device according to an embodiment of this application, as shown below. Figure 3 As shown, the display module debugging device 300 includes:

[0045] The acquisition module 301 is used to acquire the difference in brightness compensation values ​​of multiple first display modules under adjacent first test points. The testing module 302 is used to perform a lighting test on the second display modules based on at least one second test point, obtaining a first correspondence between the second test points and second brightness compensation values ​​used for compensation when display data is written to the second display modules. The second display modules are of the same type as the first display modules, and the number of second test points is less than the number of first test points. The determining module 303 is used to determine the correspondence between the lighting data and brightness compensation values ​​of the second display modules based on the first correspondence and the difference in brightness compensation values. The writing module 304 is used to write the correspondence between the lighting data and brightness compensation values ​​of the second display modules into registers included in the second display modules, so that the second display modules perform display compensation based on the correspondence between the lighting data and brightness compensation values ​​when displaying data to be displayed.

[0046] During the production of display modules, gamma calibration is typically required. Gamma is an exponential curve used by the display module to adjust the color values ​​actually output to the display screen, thereby better adapting to the user's visual experience. In the current production process, each display module needs to be lit up multiple times, and the actual brightness of the display module needs to be obtained during the lighting process to determine the display compensation value under different lighting parameters, thus obtaining the gamma calibration result. However, in this process, the higher the calibration precision, the more lighting times are required, resulting in low calibration efficiency. To improve debugging efficiency, a small number of first display modules are selected for lighting tests during the debugging process. The acquisition module 301 obtains the difference in brightness compensation values ​​of the first display modules at adjacent first test points. When debugging the second display modules of the same type as the first display modules, the test module 302 only needs to select at least one second test point for debugging to obtain the first correspondence between the second test point and the second brightness compensation value used to compensate when display data is written to the second display module. Then, the determination module 303 uses the first test point and the difference value of the first display module during the lighting test to deduce the correspondence between the lighting data and the brightness compensation value of the second display module. Finally, the writing module 304 writes the correspondence into the registers included in the second display module to complete the debugging of the second display module.

[0047] For example, if there are 10,000 display modules of the same type, 50 of them are selected as the first display module, and 15 first test points are selected for lighting tests. These first test points include the second test point. After the lighting test, the difference in brightness compensation value between the first and second test points is Δ1; the difference between the second and third test points is Δ2, and so on, obtaining Δ1-Δ15. The remaining 9,550 display modules... As the second display module, one second test point is selected for lighting test, and this second test point is the same as one of the first test points. For example, if the first first test point is selected as the second test point, after the lighting test is completed, the obtained display compensation value is subtracted by Δ1 to obtain the brightness compensation value under the second test point. Subtracting Δ2 from the brightness compensation value under the second second test point gives the brightness compensation value under the third test point, and so on, to obtain 15 test points and the corresponding brightness compensation values ​​for 15 test points. Alternatively, if the 15th first test point is selected as the second test point, after the lighting test is completed, the obtained display compensation value is added to Δ1 to obtain the brightness compensation value under the 14th test point. The brightness compensation value under the 14th second test point is added to Δ2 to obtain the brightness compensation value under the 13th test point. And so on, 15 test points and their corresponding brightness compensation values ​​can be obtained. Thus, the correspondence between the lighting data and brightness compensation values ​​of the second display module can be derived.

[0048] After the correspondence between the lighting data and the brightness compensation value of the second display module is written into the registers included in the second display module, when the second display module receives the data to be displayed, it will obtain the corresponding brightness compensation value from the register according to the data to be displayed before writing the data to be displayed into the pixel circuit. Then, when the data to be displayed is written into the pixel circuit, compensation is made by the brightness compensation value, thereby ensuring that the brightness display is normal.

[0049] In this embodiment, by utilizing the difference in brightness compensation values ​​of the first display module under adjacent first test points, when debugging the second display module, a number of second test points less than the number of first test points can be selected for debugging, thereby improving the debugging efficiency of the second display module.
