Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative work 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 of the steps of the display module debugging method according to an embodiment of the present application. Figure 1 As shown, the display module debugging method includes the following steps:

[0024] Step 101: Obtain differences in brightness compensation values of a plurality of first display modules at adjacent first test binding points.

[0025] Step 102: Perform a lighting test on the second display module according to at least one second test binding point to obtain a first correspondence between the second test binding point and a 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 the second test binding points is less than the number of the first test binding points.

[0026] Step 103 : Determine a correspondence between the lighting data of the second display module and the brightness compensation value according to the first correspondence and the difference between the plurality of brightness compensation values.

[0027] Step 104 : writing the corresponding relationship between the lighting data of the second display module and the brightness compensation value into a register included in the second display module, so that the second display module performs display compensation according to the corresponding relationship between the lighting data of the second display module and the brightness compensation value when displaying the data to be displayed.

[0028] During the production of display modules, gamma tuning is often required. Gamma is an exponential curve used by display modules to adjust the color values actually output to the display screen, thereby better suiting the user's visual experience. In the existing production process, each display module must be illuminated multiple times. During this process, the actual brightness of the display module is measured to determine the display compensation value under different lighting parameters, thereby obtaining the gamma tuning results. However, the higher the debugging accuracy, the more lighting cycles are required, resulting in lower debugging efficiency. In order to improve debugging efficiency, during the debugging process, a small number of first display modules will be selected for lighting tests to obtain the difference in brightness compensation values of the first display modules under adjacent first test binding points. Then, when debugging a second display module of the same type as the first display module, it is only necessary to select at least one second test binding point for debugging 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. Then, the first test binding point and the difference value of the first display module during the lighting test are used to deduce the first correspondence to obtain the correspondence between the lighting data and the brightness compensation value of the second display module. Finally, the correspondence is written into the register included in the second display module to complete the debugging of the second display module.

[0029] For example, there are 10,000 display modules of the same type, 50 of which are selected as the first display modules, and 15 first test binding points are selected for lighting test, the first test binding point includes the second test binding point, after the lighting test is completed, the difference in brightness compensation value between the first first test binding point and the second first test binding point of the first display module is Δ1, the difference in brightness compensation value between the second first test binding point and the third first test binding point of the first display module is Δ2, and so on, Δ1-Δ15 is obtained, and the remaining 9550 display modules are selected. The group is used as the second display module, and one second test binding point is selected for the lighting test. The second test binding point is the same as one of the first test binding points. For example, the first first test binding point is selected as the second test binding point. After the lighting test is completed, the obtained display compensation value is subtracted by Δ1 to obtain the brightness compensation value at the second test binding point. The brightness compensation value at the second second test binding point is subtracted by Δ2 to obtain the brightness compensation value at the third test binding point. By analogy, 15 test binding points and the brightness compensation values corresponding to the 15 test binding points can be obtained. Alternatively, if the 15th first test binding point is selected as the second test binding point, after the lighting test is completed, the obtained display compensation value is added by Δ1 to obtain the brightness compensation value at the 14th test binding point, and the brightness compensation value at the 14th second test binding point is added by Δ2 to obtain the brightness compensation value at the 13th test binding point. Similarly, 15 test binding points and the brightness compensation values corresponding to the 15 test binding points can be obtained, and then the correspondence between the lighting data of the second display module and the brightness compensation value can be derived.

[0030] After the correspondence between the lighting data of the second display module and the brightness compensation value is written into the register 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 writing the data to be displayed into the pixel circuit, compensation is performed using the brightness compensation value, thereby ensuring normal brightness display.

[0031] In an embodiment of the present application, by utilizing the difference in brightness compensation values of the first display module at adjacent first test binding points, when debugging the second display module, a second test binding point that is smaller than the number of first test binding points can be selected for debugging, thereby improving the debugging efficiency of the second display module.

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

[0033] Step 201: Control a first display module to light up according to a plurality of first test binding points, and obtain a plurality of first actual brightnesses when the first display module is lit up.

[0034] Step 202 : determining differences in brightness compensation values of the plurality of first display modules at adjacent first test binding points based on target brightness corresponding to the plurality of first test binding points and the plurality of first actual brightnesses.

[0035] In order to determine the difference in brightness compensation values of the first display module at adjacent first test binding points, it is necessary to obtain the first actual brightness of the first display module at different first test binding points. Therefore, the first display module is first controlled to light up according to the first first test binding point, and the first 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 binding point, the normal brightness of the normal display module at the first test binding point can be determined, and this normal brightness is used as the target brightness corresponding to the first test binding point. Then, based on the brightness difference between the first actual brightness of the first display module at the first test binding point and the target brightness, the compensation value of the first display module at the first test binding point is determined. Finally, based on the target brightness corresponding to the multiple first test binding points and the multiple first actual brightnesses, the difference in brightness compensation values of the multiple first display modules at adjacent first test binding points is determined.

[0036] Specifically, the difference in brightness compensation values of the first display module at adjacent first test binding points includes multiple sub-differences corresponding to compensation values of different color channels. For example, it may include an R (red) sub-difference, a G (green) sub-difference, and a B (blue) sub-difference. For example, Δ1 includes ΔR1, ΔG1, and ΔB1. This can improve 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, and 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 may be as shown in Table 1:

[0039] Table 1

[0040]

[0041] Among them, Step is used to represent the compensation value, Step AA is used to represent the brightness compensation value corresponding to the first display module at the first grayscale under brightness level A (the example in the table is 255), Delta is used to represent the difference value, and Delta AAAB is used to represent the difference value between Step AA and Step AB corresponding to adjacent grayscales.

[0042] Furthermore, it should be noted that since display modules display lower brightness at low grayscales, and low brightness typically requires greater compensation than high brightness, the values of the first test tie points are spaced farther apart at high grayscales and closer together at low grayscales. Furthermore, since the number of first display modules is relatively small, the number of first test tie points can be increased to improve debugging accuracy.

[0043] Specifically, the second test binding point is determined based on the first test binding point. The second test binding point is a partial test binding point in the first test binding point, that is, the first test binding point includes the second test binding point. Taking the first test binding point as Table 1 as an example, the grayscale values included in the second test binding point can be selected from 255, 239, 207, 143, 111, 79, 63, 47, 31, 23, 15, 11, 7, 3 and 1. In order to improve the debugging efficiency of the second display module, only one grayscale value can be selected, but for ease of calculation, the value must be a boundary value, that is, 255 or 1. In addition, in order to improve the debugging accuracy of the second display module, an additional grayscale value can be selected, and the middle value of the first test binding point can be selected. For example, the grayscale values included in the second test binding point can be selected from two grayscale values of 255 and 63.

[0044] Figure 3 Schematic diagram of a display module debugging device according to an embodiment of the present application. Figure 3 As shown, the display module debugging device 300 includes:

[0045] An acquisition module 301 is used to obtain the difference in brightness compensation values of multiple first display modules at adjacent first test binding points. A test module 302 is used to perform a lighting test on a second display module based on at least one second test binding point to obtain a first correspondence between the second test binding point and a 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. A determination module 303 is used to determine the correspondence between the lighting data and the brightness compensation value of the second display module based on the first correspondence and the difference in multiple brightness compensation values. A write module 304 is used to write the correspondence between the lighting data and the brightness compensation value of the second display module into a register included in the second display module, so that when the second display module displays the data to be displayed, display compensation is performed according to the correspondence between the lighting data and the brightness compensation value of the second display module.

[0046] During the production of display modules, gamma tuning is often required. Gamma is an exponential curve used by display modules to adjust the color values actually output to the display screen, thereby better suiting the user's visual experience. In the existing production process, each display module must be illuminated multiple times. During this process, the actual brightness of the display module is measured to determine the display compensation value under different lighting parameters, thereby obtaining the gamma tuning results. However, the higher the debugging accuracy, the more lighting cycles are required, resulting in lower debugging efficiency. In order to improve debugging efficiency, a small number of first display modules will be selected for lighting test during the debugging process. The acquisition module 301 obtains the difference in brightness compensation value of the first display module under adjacent first test binding points. Then, when debugging the second display module of the same type as the first display module, the test module 302 only needs to select at least one second test binding point for debugging, and obtain the first correspondence between the second test binding point and the second brightness compensation value used to compensate when the display data is written to the second display module. Then, the determination module 303 uses the first test binding point and the difference value of the first display module during the lighting test to deduce the first correspondence to obtain 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 register included in the second display module to complete the debugging of the second display module.

[0047] For example, there are 10,000 display modules of the same type, 50 of which are selected as the first display modules, and 15 first test binding points are selected for lighting test, the first test binding point includes the second test binding point, after the lighting test is completed, the difference in brightness compensation value between the first first test binding point and the second first test binding point of the first display module is Δ1, the difference in brightness compensation value between the second first test binding point and the third first test binding point of the first display module is Δ2, and so on, Δ1-Δ15 is obtained, and the remaining 9550 display modules are selected. The group is used as the second display module, and one second test binding point is selected for the lighting test. The second test binding point is the same as one of the first test binding points. For example, the first first test binding point is selected as the second test binding point. After the lighting test is completed, the obtained display compensation value is subtracted by Δ1 to obtain the brightness compensation value at the second test binding point. The brightness compensation value at the second second test binding point is subtracted by Δ2 to obtain the brightness compensation value at the third test binding point. By analogy, 15 test binding points and the brightness compensation values corresponding to the 15 test binding points can be obtained. Alternatively, if the 15th first test binding point is selected as the second test binding point, after the lighting test is completed, the obtained display compensation value is added by Δ1 to obtain the brightness compensation value at the 14th test binding point, and the brightness compensation value at the 14th second test binding point is added by Δ2 to obtain the brightness compensation value at the 13th test binding point. Similarly, 15 test binding points and the brightness compensation values corresponding to the 15 test binding points can be obtained, and then the correspondence between the lighting data of the second display module and the brightness compensation value can be derived.

[0048] After the correspondence between the lighting data of the second display module and the brightness compensation value is written into the register 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 writing the data to be displayed into the pixel circuit, compensation is performed using the brightness compensation value, thereby ensuring normal brightness display.

[0049] In an embodiment of the present application, by utilizing the difference in brightness compensation values of the first display module at adjacent first test binding points, when debugging the second display module, a second test binding point that is smaller than the number of first test binding points can be selected for debugging, thereby improving the debugging efficiency of the second display module.
