[0115] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0116] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0117] As described in the background art, the display device has a problem of poor display in the case of a partitioned multi-frequency display mode. The inventors have found that the reason for the above problem is that in order to meet the demand of displaying pictures with different refresh frequencies on the same display screen, for example, part of the area of the display screen is a game video picture, and the other part is an e-book picture, the display mode of the display device is set to include a partitioned multi-frequency display mode. In the partitioned multi-frequency display mode, the display area of the display device includes at least two display partitions, and the refresh frequencies of at least two display partitions are different. For example, the refresh frequency of the display partition corresponding to the game video picture is higher than the refresh frequency of the display partition corresponding to the e-book picture. Due to the difference in refresh frequency of different display partitions, there is a difference in brightness between different display partitions under the same display grayscale, resulting in poor display in the partitioned multi-frequency display mode, affecting the display effect.

[0118] Based on the above reasons, an embodiment of the present invention provides a method for determining display data of a display module. The display data obtained by this determination method can be used to perform brightness compensation on the display module to improve the brightness difference between display partitions with different refresh frequencies in a partitioned multi-frequency display mode.

[0119] Figure 1 This is a schematic diagram of the structure of a display module provided by an embodiment of the present invention, with reference to Figure 1 In the partition multi-frequency display mode, the display module includes at least two display partitions AA0, and the refresh frequencies of the at least two display partitions AA0 are different. Figure 1 The schematic diagram shows a case where the display module includes two display partitions AA0. The refresh frequencies corresponding to the two display partitions AA0 are different. For example, the two display partitions are respectively recorded as the first display partition AA1 and the second display partition AA2. The first display partition AA1 and the second display partition AA2 can be arranged along the extension direction of the data lines in the display panel, and / or arranged from the side close to the driver chip to the side away from the driver chip. For example, the first refresh frequency corresponding to the first display partition AA1 is higher than the second refresh frequency corresponding to the second display partition AA2. The first display partition AA1 is usually called the hot zone, and the second display partition AA2 is usually called the cold zone. For example, the first refresh frequency is 120Hz and the second refresh frequency is 1Hz. Figure 2 This is a flow chart of a method for determining display data of a display module provided by an embodiment of the present invention, with reference to Figure 2 , the display data determination method includes:

[0120] S110 , selecting a plurality of display modules, and determining public display data corresponding to the display partition to be compensated based on brightness differences between adjacent display partitions at different refresh rates under a preset display screen of the initial driving data of the display modules.

[0121] The preset display image includes a display image at a preset grayscale with a preset display brightness level; the display subarea to be compensated includes at least one display subarea. The display subarea to be compensated and adjacent display subareas to the display subarea to be compensated have different refresh rates. Optionally, the preset display image is a white image.

[0122] The number of preset display brightness levels may be one or at least two; the number of preset grayscales may be one or at least two.

[0123] In some embodiments, the brightness difference between adjacent display partitions with different refresh rates of the display partitions to be compensated of at least some display modules under the public display data is smaller than the brightness difference between adjacent display partitions with different refresh rates of the display partitions to be compensated under the initial driving data.

[0124] In some embodiments, in at least some display modules, the brightness difference between adjacent display partitions meets the target brightness requirement under a preset display screen of the public version display data.

[0125] The target brightness requirement may include that the brightness difference between adjacent display subareas with different refresh rates in the display module is less than or equal to a preset brightness threshold. Optionally, the brightness difference between adjacent display subareas may be equal to the difference between the average brightness of at least a portion of the area in one display subarea and the average brightness of at least a portion of the area in another display subarea, or the ratio of the brightness difference to the average brightness of at least a portion of the area in one display subarea.

[0126] Among them, multiple display modules can be selected from the same batch or from different batches, and the embodiments of the present invention are not specifically limited here. In some embodiments, multiple display modules can be selected for each batch of display modules, and steps S110-S130 can be performed to determine the final display data corresponding to each batch of display modules. In this step, after selecting multiple display modules, for each display module, after providing the initial driving data corresponding to the preset display screen to the display module, the brightness difference of adjacent display partitions with different refresh frequencies in the display module is obtained. Specifically, the brightness difference of the display partition to be compensated and the display partition adjacent to the display partition to be compensated can be obtained, and then the public version display data corresponding to the preset grayscale of the preset display brightness level of the display partition to be compensated is determined based on the brightness difference.

[0127] In some embodiments, the method for determining public version display data based on the brightness difference between adjacent display partitions with different refresh rates in a display module includes performing brightness debugging on the display partition to be compensated in at least one display module among a plurality of display modules. The process of performing brightness debugging on the display partition to be compensated may be to adjust the driving data corresponding to the display partition to be compensated, that is, to adjust the initial driving data corresponding to the display partition to be compensated to other driving data, and in this process, obtain the brightness difference between adjacent display partitions with different refresh rates until the display partition to be compensated and the adjacent display partition meet the target brightness requirement, and the debugging of the display module in this step is completed. Then, the public version display data is determined based on the driving data corresponding to the display partition to be compensated when at least some of the display modules meet the target brightness requirement under the preset display screen.

[0128] In other embodiments, the method for determining public display data based on the brightness difference between adjacent display partitions with different refresh frequencies in a display module includes obtaining, through preliminary testing, the correspondence between the brightness difference between adjacent display partitions with different refresh frequencies in multiple display modules and the public display data. Schematically, the correspondence between the mean, median, mode, etc. of the brightness difference between adjacent display partitions with different refresh frequencies in multiple display modules and the public display data can be obtained in advance through preliminary experiments, and then the public display data is determined based on the correspondence.

[0129] It should be noted that due to the voltage drop in the signal lines of the display panel during signal transmission, the display panel may experience uneven brightness in both the partitioned multi-frequency display mode and the non-partitioned multi-frequency display mode (where the refresh rate of the entire display area of the display panel is the same). In some embodiments of the present invention, the initial drive data may include compensation data for display unevenness caused by the signal transmission voltage drop; in other embodiments, the initial drive data may not include compensation data for display unevenness caused by the signal transmission voltage drop.

[0130] S120 , when the brightness difference between adjacent display partitions with different refresh rates of the display partition to be compensated meets the target brightness requirement under the public display data, determine the public display data corresponding to the display partition to be compensated as the final display data.

[0131] After determining the public version display data, the public version display data can be provided to the display partition to be compensated of the display module. Exemplarily, the public version display data is provided to each display module of at least one batch. Optionally, at least one batch of display modules may include multiple display modules selected in S110, and also include display modules other than the multiple display modules selected in S110. Optionally, initial drive data can still be provided for display partitions other than the display partition to be compensated. Then, the brightness difference between adjacent display partitions with different refresh frequencies of the display partition to be compensated under the public version display data is obtained, and it is determined whether the brightness difference meets the target brightness requirement. When the target brightness requirement is met, the public version display data corresponding to the display partition to be compensated is determined as the final display data. In this way, when the brightness difference between adjacent display partitions with different refresh rates of the display partition to be compensated meets the target brightness requirement under the public display data, there is no need to further adjust the brightness of the display module. On the one hand, it can ensure that the display module is in the partitioned multi-frequency display mode, when the brightness difference between adjacent display partitions with different refresh rates of the display partition to be compensated meets the target brightness requirement under the public display data, thereby improving the display effect of the display panel in the partitioned multi-frequency display mode; on the other hand, it can save debugging time.

[0132] The final display data is compensation data for the initial driving data, or driving data obtained after the initial driving data is compensated by the compensation data.

[0133] In some embodiments, the initial driving data includes a gamma register value; in other embodiments, the initial driving data includes a data voltage. Accordingly, the compensation data may be a compensation value for the gamma register value or a compensation value for the data voltage; or the compensation data may be a gamma register value obtained by compensating the gamma register value corresponding to the initial driving data with the compensation value, or a data voltage obtained by compensating the data voltage corresponding to the initial driving data with the compensation value.

[0134] S130 : When the brightness difference between adjacent display partitions with different refresh rates does not meet the target brightness requirement under the public display data of the display partition to be compensated, perform brightness adjustment on the display partition to be compensated to determine final display data that meets the target brightness requirement.

[0135] Specifically, for a display module in which the brightness difference between adjacent display partitions with different refresh frequencies does not meet the target brightness requirement under the public display data, the brightness of the display partition to be compensated is debugged again. That is, for such a display module, the public display data is adjusted until the brightness difference between adjacent display partitions with different refresh frequencies meets the target brightness requirement, thereby obtaining the final display data.

[0136] It should be noted that, according to the partitioning situation and refresh frequency combination of the display module, where the refresh frequency combination situation includes the refresh frequency of each display partition in the display module, the display partition to be compensated in the display module can be one or at least two. The display data determination method of an embodiment of the present invention can be used to separately determine the final display data corresponding to each display partition to be compensated at a preset gray scale of a preset display brightness level, so as to improve the brightness difference between different display partitions.

[0137] The display data determination method of the display module of the embodiment of the present invention is through selecting multiple display modules and determining the public version display data corresponding to the display partitions to be compensated of the multiple display modules. For the display module whose display partition to be compensated has the brightness difference of adjacent display partitions with different refresh frequencies that meets the target brightness requirement under the public version display data, the public version display data corresponding to the display partition to be compensated is determined as the final display data. For the display module whose display partition to be compensated has the brightness difference of adjacent display partitions with different refresh frequencies that does not meet the target brightness requirement under the public version display data, the display partition to be compensated is brightness debugged to determine the final display data that meets the target brightness requirement. In this way, on the one hand, it can be ensured that the display module is in the partition multi-frequency display mode, and the brightness difference of adjacent display partitions with different refresh frequencies under the final display data of the display partition to be compensated meets the target brightness requirement, thereby improving the display effect of the display panel in the partition multi-frequency display mode; on the other hand, by determining the public version display data, debugging time can be saved, thereby improving the efficiency of the display data determination method.

[0138] Figure 3 Another method for determining display data of a display module provided by an embodiment of the present invention is provided. Figure 3 , the display data determination method of the display module includes:

[0139] S210: Select multiple display modules.

[0140] The method of selecting the multiple display modules is the same as that of the above embodiment of the present invention, and will not be repeated here.

[0141] S220: Determine first display data corresponding to the display partition to be compensated when at least some of the display modules meet the target brightness requirement based on brightness differences between adjacent display partitions at different refresh rates under a preset display screen of the initial driving data.

[0142] Specifically, when the brightness differences of adjacent display partitions with different refresh rates meet the target brightness requirements under the preset screen of the initial driving data of the display module, the initial driving data can be used as the first display data corresponding to the display partition to be compensated in the display module.

[0143] When the brightness difference between adjacent display partitions with different refresh rates does not meet the target brightness requirement under the preset screen of the initial driving data of the display module, the first display data corresponding to the display partition to be compensated in the display module can be determined by performing brightness adjustment on the display partition to be compensated or other methods.

[0144] Figure 4 This is the detailed step diagram of S220, reference Figure 4 Optionally, for a display module, when determining the first display data corresponding to the display partition to be compensated by brightness debugging, S220 may include: S221, adjusting the initial driving data corresponding to the display partition to be compensated in at least some of the display modules based on the brightness difference of adjacent display partitions with different refresh frequencies under the preset display screen of the initial driving data of multiple display modules, so that the brightness difference of adjacent display partitions with different refresh frequencies under the adjusted driving data of at least some of the display modules meets the target brightness requirement; S222, using the adjusted driving data or compensation data as the first display data corresponding to the display partition to be compensated; wherein the compensation data is used to compensate the initial driving data to obtain the adjusted driving data. Specifically, for the display module for adjusting the initial driving data, the adjusted driving data or compensation data is used as the first display data corresponding to the display partition to be compensated.

[0145] Exemplarily, when the brightness difference between adjacent display partitions with different refresh frequencies does not meet the target brightness requirement under the preset screen of the initial driving data of the display module, the initial driving data corresponding to the display partition to be compensated in the display module is adjusted. In this process, the brightness difference between adjacent display partitions with different refresh frequencies in the display panel is obtained in real time. When the brightness difference meets the target brightness requirement, the corresponding adjusted driving data is determined as the first display data, or the compensation data corresponding to the adjusted driving data is determined as the first display data.

[0146] Optionally, the compensation data is equal to the difference between the adjusted driving data and the initial driving data.

[0147] In other embodiments, the first display data corresponding to the display partition to be compensated in the display module can be determined by other methods. For example, through preliminary testing, the corresponding relationship between the brightness difference between adjacent display partitions with different refresh rates in the display module and the first display data is obtained, and then the first display data is determined based on this corresponding relationship.

[0148] S230 : Determine public version display data according to first display data corresponding to display partitions to be compensated in at least some display modules.

[0149] In some embodiments, in S220, the first display data corresponding to the display partition to be compensated is determined when the multiple display modules meet the target brightness requirements based on the brightness difference of adjacent display partitions with different refresh frequencies under the preset display screen of the initial drive data. In the case where the adjusted drive data is used as the first display data, in S230, the number of display modules corresponding to the same first display data in the selected multiple display modules can be counted, and the first display data corresponding to the display module with the largest number of corresponding data can be determined as the public version display data corresponding to the display partition to be compensated. In some cases, the first display data corresponding to the display partition to be compensated may be different in each display module, or the first display data corresponding to the display module with the largest number of corresponding data cannot be found, and the public version display data cannot be determined using the above determination method.

[0150] Therefore, in some embodiments, the public version display data can also be determined in the following manner. Optionally, in some embodiments, S220 includes: dividing the first display data corresponding to the display partition to be compensated into multiple gears based on the first display data corresponding to the same display partition to be compensated in at least some display modules; determining the gear of the first display data corresponding to the display module based on the brightness difference between adjacent display partitions with different refresh rates under the first display data of the display partition to be compensated in the display module; Figure 5 This is the detailed step diagram of S230, refer to Figure 5 S230 includes S231, determining the reference gear positions corresponding to the display partitions to be compensated of the multiple display modules based on the gear positions of the first display data corresponding to the display partitions to be compensated of the multiple display modules; S232, determining the first display data corresponding to the reference gear position as reference display data when the first display data is adjusted drive data; and S233, determining the reference display data based on the first display data corresponding to the reference gear position and the initial drive data when the first display data is compensation data. For example, the reference display data is determined by summing the first display data corresponding to the reference gear position and the initial drive data.

[0151] Specifically, when dividing the first display data corresponding to the display partition to be compensated into multiple gears based on the first display data corresponding to the same display partition to be compensated in at least some of the display modules, for each display partition to be compensated, the gear division can be performed based on the first display data corresponding to the same display partition to be compensated in at least some of the selected multiple display modules. In some embodiments, the division can be performed based on the difference in the first display data corresponding to different display modules. When the first display data corresponding to the same display partition to be compensated differ significantly from each other, the first display data can be divided into more gears; when the first display data corresponding to the same display partition to be compensated differ slightly from each other, the first display data can be divided into fewer gears, so that a greater number of display modules can meet the target brightness requirements under the determined standard gears.

[0152] Optionally, according to the first display data corresponding to the same display partition to be compensated in at least some of the display modules, dividing the first display data corresponding to the display partition to be compensated into multiple gears includes: determining the maximum difference value and the minimum difference value of the brightness difference according to the brightness difference of adjacent display partitions with different refresh frequencies under the preset display screen of the initial driving data of the multiple display modules; and dividing the first display data corresponding to the display partition to be compensated into the first display data of multiple gears according to the first display data corresponding to the maximum difference value and the first display data corresponding to the minimum difference value.

[0153] Specifically, for multiple selected display modules, the brightness difference between adjacent display subareas at different refresh rates under the preset display screen of the initial drive data can be obtained for each display module, and then the display module with the largest brightness difference can be determined to obtain the maximum difference value; and the display module with the smallest brightness difference can be determined to obtain the minimum difference value. By performing brightness adjustment on the display subarea to be compensated in the display module corresponding to the maximum difference value, the first display data corresponding to the display subarea to be compensated in the display module corresponding to the maximum difference value can be obtained and used as the first display data corresponding to the maximum difference value. By performing brightness adjustment on the display subarea to be compensated in the display module corresponding to the minimum difference value, the first display data corresponding to the display subarea to be compensated in the display module corresponding to the minimum difference value can be obtained and used as the first display data corresponding to the minimum difference value. The first display data corresponding to the maximum difference value and the first display data corresponding to the minimum difference value are then divided into multiple levels of first display data. In this case, at least some of the display modules include the display module corresponding to the maximum difference value and the display module corresponding to the minimum difference value.

[0154] In some embodiments, the first display data corresponding to the maximum difference value and the first display data corresponding to the minimum difference value are evenly divided into multiple levels of first display data. In other embodiments, the multiple levels may be unequally divided, and this is not specifically limited in the embodiments of the present invention. For example, the first display data corresponding to the maximum difference value and the first display data corresponding to the minimum difference value are divided into 12 levels of first display data. Together with the first display data corresponding to the maximum difference value and the first display data corresponding to the minimum difference value, a total of 14 levels of first display data can be divided.

[0155] Optionally, determining the gear of the first display data corresponding to the display module based on the brightness difference between adjacent display partitions at different refresh rates under the first display data of the display partition to be compensated of the display module includes: for each display module, determining the gear corresponding to the minimum brightness difference among the multiple gears based on the brightness difference between adjacent display partitions at different refresh rates under the first display data of the display partition to be compensated of the display module, and determining the gear corresponding to the minimum brightness difference as the gear corresponding to the first display data of the display module. S233 includes: determining the gear corresponding to the minimum brightness difference the most times among the multiple display modules as the public version gear corresponding to the display partitions to be compensated of the multiple display modules, and determining the display data corresponding to the public version gear as the public version display data.

[0156] Specifically, for each of the multiple selected display modules, the first display data of multiple levels can be provided to the display partition to be compensated, and the brightness difference of adjacent display partitions with different refresh frequencies under each level can be obtained, so as to determine the level of the first display data corresponding to the minimum brightness difference of the display module. Figure 6 This is a curve diagram showing the brightness difference of one display module under the first display data of multiple gears. Figure 6 FIG schematically shows a case where the brightness difference of the display module is under the first display data of multiple gears, wherein the horizontal axis represents the gear of the first display data and the vertical axis represents the brightness difference. Figure 6 At the gear position corresponding to the lowest point B of the curve, the brightness difference is the smallest.

[0157] Afterwards, the gears corresponding to the minimum brightness differences among multiple display modules can be counted, and the gears with the largest minimum brightness differences can be obtained as the reference gears. This ensures that, under the reference display data, the brightness differences between different display partitions of a large number of display modules are small. This allows, when the reference display data is subsequently applied to more display modules, to reduce the number of display modules that require further debugging and further improve the efficiency of the display data determination method.

[0158] For example, 20 display modules are selected, and the number of gears is 14. For the same display area to be compensated, 10 display modules have the minimum brightness difference at gear 5, 5 display modules have the minimum brightness difference at gear 3, 2 display modules have the minimum brightness difference at gear 10, 1 display module has the minimum brightness difference at gear 8, 1 display module has the minimum brightness difference at gear 12, and 1 display module has the minimum brightness difference at gear 6. Then, gear 10 can be determined as the standard gear.

[0159] S240 : Under the public display data, if the brightness difference between adjacent display partitions with different refresh rates of the display partition to be compensated meets the target brightness requirement, determine the public display data corresponding to the display partition to be compensated as the final display data.

[0160] S250 : When the brightness difference between adjacent display partitions with different refresh rates does not meet the target brightness requirement under the public display data of the display partition to be compensated, perform brightness adjustment on the display partition to be compensated to determine final display data that meets the target brightness requirement.

[0161] Optionally, after selecting multiple display modules, the method further includes: performing gamma debugging on the multiple display modules to determine initial driving data.

[0162] Specifically, the initial driving data is determined after selecting multiple display modules in S110 and before determining the public display data corresponding to the display partition to be compensated based on the brightness difference between adjacent display partitions with different refresh rates under the preset display screen of the initial driving data. The initial driving data is determined after S210 and before S220.

[0163] Among them, when performing gamma debugging, the driving data can be debugged according to whether the brightness of the center point of the display module reaches the target brightness and whether the color coordinates of the center point reach the target color coordinates. The driving data corresponding to when the brightness of the center point of the display module reaches the target brightness and the color coordinates of the center point reach the target color coordinates is used as the first driving data, and the initial driving data is determined based on the first driving data corresponding to multiple display modules.

[0164] In some embodiments, gamma debugging is performed on multiple selected display modules at a preset display brightness level to obtain the first driving data corresponding to each display module at multiple binding point grayscales; the average value, median value or mode of the first driving data corresponding to the multiple display modules at the binding point grayscales is determined as the initial driving data corresponding to the binding point grayscale.

[0165] By performing gamma debugging at a preset display brightness level, the first driving data corresponding to the display module is obtained through actual debugging, and the initial driving data is obtained based on the first driving data, so that under the obtained initial driving data, the brightness of the preset display screen at the preset grayscale of the preset display brightness level is closer to the target brightness, shortening the time for subsequent adjustment of the initial driving data to obtain the first display data, and improving the efficiency of the display data determination method.

[0166] Optionally, the initial driving data corresponding to other grayscales are determined based on the initial driving data corresponding to the grayscale of the binding point. Exemplarily, the initial driving data corresponding to other grayscales can be obtained by interpolation calculation based on the initial driving data corresponding to the grayscale of the binding point.

[0167] Optionally, gamma tuning is performed on each of the selected multiple display modules at multiple binding point grayscales at multiple display brightness levels to determine initial driving data corresponding to each subpixel of the display module at the multiple binding point grayscales at each display brightness level. Accordingly, initial driving data at each grayscale at other display brightness levels not determined through gamma tuning can be obtained by interpolation calculation based on the initial driving data at the display brightness levels determined through gamma tuning.

[0168] Wherein, the display module may include red sub-pixels, green sub-pixels and blue sub-pixels, and the initial driving data include initial driving data corresponding to the red sub-pixels, initial driving data corresponding to the green sub-pixels and initial driving data corresponding to the blue sub-pixels respectively. In some embodiments, the initial driving data of the corresponding color sub-pixels are obtained by performing gamma debugging under a monochrome display screen. Exemplarily, gamma debugging is performed under a red display screen, a green display screen and a blue display screen respectively, and the initial driving data corresponding to the red sub-pixels, the initial driving data corresponding to the green sub-pixels and the initial driving data corresponding to the blue sub-pixels are obtained respectively. In other embodiments, the initial driving data corresponding to the red sub-pixels, the initial driving data corresponding to the green sub-pixels and the initial driving data corresponding to the blue sub-pixels are obtained by performing gamma debugging under a white display screen.

[0169] For example, at a preset display brightness level, the maximum grayscale corresponding to 90 nits is used. Gamma tuning is performed at this preset display brightness level. The center point color coordinates are assumed to be (0.313, 0.320), and the center point target brightness is set based on the corresponding binding point grayscale. For example, 15 binding point grayscales are 0, 1, 3, 7, 15, 23, 31, 47, 63, 79, 111, 143, 207, 239, and 255. The first drive data corresponding to the red subpixel, the first drive data corresponding to the green subpixel, and the first drive data corresponding to the blue subpixel are obtained. For example, the initial drive data is the gamma register value. The first drive data of multiple modules is averaged to obtain the final register values for the 15 grayscales, which serve as the initial drive data. Register values for intermediate grayscales are calculated using linear interpolation, with a register value range of 0-4095.

[0170] Table 1 shows the initial display data corresponding to 15 gray levels.

[0173]

[0174] According to Vdata = VGMP - [(VGMP - VGSP) / 4095] * gamma register value, where Vdata represents the data voltage, VGMP represents the first reference voltage, and VGSP represents the second reference voltage, and VGMP > VGSP. The larger the gamma register value, the smaller the data voltage and the higher the brightness of the display module. According to the Gamma 2.2 curve, in the 0-255 grayscale, the brightness L of a certain grayscale X = (X / 255) to the power of 2.2 * 90nit. By finding the relationship between grayscale, brightness, and register value, it is convenient to calculate the first display data and set the corresponding compensation level in the subsequent steps.

[0175] Optionally, S130 and S250 in the above embodiments include: adjusting the display data of the display partition to be compensated to the first display data of the corresponding gear according to the size of the brightness difference between adjacent display partitions with different refresh frequencies under the public display data of the display partition to be compensated, and the preset correspondence between the brightness difference and the number of adjusted gears.

[0176] Specifically, when the brightness difference between adjacent display partitions with different refresh rates in the display partition to be compensated does not meet the target brightness requirement under the public version display data, if one gear is adjusted each time starting from the public version display data, the brightness debugging time may be longer. In this embodiment, the corresponding relationship between the brightness difference between adjacent display partitions with different refresh rates in the display partition to be compensated and the number of gears that need to be adjusted under the public version display data is obtained in advance as a preset corresponding relationship. Exemplarily, by performing preliminary tests on multiple display modules, the corresponding relationship between the brightness difference between adjacent display partitions with different refresh rates in the display partition to be compensated and the number of gears that need to be adjusted under the public version display data is obtained. After obtaining the brightness difference between adjacent display partitions with different refresh rates in the display partition to be compensated under the public version display data, the number of gears to be adjusted is determined in the preset corresponding relationship based on the brightness difference, and then the gear of the first display data is adjusted according to the determined number. In this way, the debugging speed can be accelerated and the efficiency of the display data determination method can be improved.

[0177] Optionally, the number of levels for adjusting the first display data is positively correlated with the brightness difference; that is, the greater the brightness difference, the more levels for adjusting the experience display data.

[0178] Exemplarily, the preset corresponding relationship includes adjusting m1 gears when the brightness difference is greater than or equal to the first percentage; adjusting m2 gears when the brightness difference is greater than or equal to the second percentage and less than the first percentage; adjusting m3 gears when the brightness difference is greater than or equal to the third percentage and less than the second percentage, where m1>m2>m3.

[0179] For example, the first percentage is equal to 15%, the second percentage is equal to 10%, and the third percentage is equal to 5%. m1=3, m2=2, and m3=1.

[0180] Optionally, the display data of the display partition to be compensated is adjusted to the first display data of the corresponding gear according to the size and direction of the brightness difference between adjacent display partitions with different refresh frequencies under the public display data of the display partition to be compensated, and the preset correspondence between the brightness difference and the number of adjusted gears.

[0181] The direction of the brightness difference between adjacent display partitions with different refresh frequencies can be represented by the positive or negative value of the brightness difference between adjacent display partitions with different refresh frequencies. For example, for adjacent first and second display partitions, the refresh frequencies of the first and second display partitions are different, and the brightness of the first display partition is greater than that of the second display partition, then the brightness difference is a positive value; and the brightness difference of the first display partition is less than that of the second display partition, then the brightness difference is a negative value. In the case of positive and negative brightness differences, the direction of the brightness difference is opposite. When adjusting the gear of the first display data, when the brightness difference is positive, the brightness of the first display partition can be reduced and / or the brightness of the second display partition can be increased by adjusting the corresponding number of gears according to the preset corresponding relationship; when the brightness difference is negative, the brightness of the first display partition can be increased and / or the brightness of the second display partition can be reduced by adjusting the corresponding number of gears according to the preset corresponding relationship.

[0182] Optionally, after adjusting the display data of the display partition to be compensated to the first display data of the corresponding gear, it also includes: after adjusting the gear of the first display data corresponding to the display partition to be compensated, when the brightness difference between adjacent display partitions with different refresh frequencies under the preset display screen does not meet the target brightness requirement, adjust the gear of the first display data corresponding to the display partition to be compensated according to the brightness difference and the preset corresponding relationship until the brightness difference meets the target brightness requirement.

[0183] Specifically, after adjusting the level of the first display data corresponding to the display partition to be compensated according to the preset corresponding system, the brightness difference between adjacent display partitions can be obtained again. If the brightness difference does not meet the target brightness requirement, the level of the first display data corresponding to the display partition to be compensated can be adjusted again according to the brightness difference and the preset corresponding relationship until the brightness difference meets the target brightness requirement, so that under the final display data obtained, the brightness difference can meet the target brightness requirement.

[0184] Figure 7 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 7Optionally, in the partitioned multi-frequency display mode, the display module includes a first display partition AA1, a second display partition AA2, and a third display partition AA3, and the second display partition AA2 is located between the first display partition AA1 and the third display partition AA3; wherein, the refresh frequencies of the first display partition AA1 and the second display partition AA2 are not equal, and the refresh frequencies of the third display partition AA3 and the second display partition AA2 are not equal. The refresh frequencies of the first display partition AA1 and the third display partition AA3 may be equal or unequal, and are not specifically limited in this embodiment of the present invention. For example, the refresh frequencies of the first display partition AA1 and the third display partition AA3 are 1 Hz, and the refresh frequency of the second display partition AA2 is 120 Hz.

[0185] Optionally, the display module further includes data lines, and the first display area AA1, the second display area AA2, and the third display area AA3 are arranged along a first direction, which may be the direction in which the data lines extend. The display module further includes a driver chip, and the first display area AA1, the second display area AA2, and the third display area AA3 are arranged from a side closer to the driver chip to a side farther away from the driver chip, that is, the first direction may be from a side closer to the driver chip to a side farther away from the driver chip.

[0186] Optionally, the display partition to be compensated includes a first display partition AA1, and the brightness difference between adjacent display partitions includes the brightness difference between the first display partition AA1 and the second display partition AA2; the display partition to be compensated includes a third display partition AA3, and the brightness difference between adjacent display partitions includes the brightness difference between the second display partition AA2 and the third display partition AA3. The final display data corresponding to the first display partition AA1 is determined based on whether the brightness difference between the first display partition AA1 and the second display partition AA2 meets the target brightness requirement under the corresponding public display data of the first display partition AA1; the final display data corresponding to the third display partition AA3 is determined based on whether the brightness difference between the third display partition AA3 and the second display partition AA2 meets the target brightness requirement under the corresponding public display data of the third display partition AA3. That is, the final display data corresponding to the first display partition AA1 and the final display data corresponding to the third display partition AA3 can be obtained respectively using the display data determination method of any embodiment of the present invention. That is, the final display data corresponding to the first display partition AA1 can be obtained based on the brightness difference between the first display partition AA1 and the second display partition AA2, and the final display data corresponding to the third display partition AA3 can be obtained based on the brightness difference between the second display partition AA2 and the third display partition AA3. The brightness difference can be judged more accurately, the brightness difference can be compensated in a targeted manner, and the display effect can be improved.

[0187] In some embodiments, the display data determination method of the display module further includes: determining the final display data of the second display partition AA2 using the initial drive data. Specifically, when performing gamma debugging, the drive data can be debugged based on whether the brightness of the center point of the display module reaches the target brightness and whether the color coordinates of the center point reach the target color coordinates. Then, the display partition where the center point is located (usually the second display partition AA2) is closer to the target brightness than the first display partition AA1 and the third display partition AA3 under the initial drive data. In this embodiment, the final display data of the second display partition AA2 is determined using the initial drive data. After gamma debugging, the display data determination method of the embodiment of the present invention is used to determine the final display data corresponding to the first display partition AA1 and the third display partition AA3 respectively. There is no need to perform brightness debugging on the second display partition AA2. While improving the brightness difference between different display partitions, the efficiency of the display data determination method is improved.

[0188] Specifically, the brightness difference between adjacent display partitions is most obvious near the dividing line. Figure 7 Therefore, optionally, the brightness difference between adjacent display partitions includes the brightness difference of the preset area Y0 in the adjacent display partitions; wherein, the preset area Y0 is located near the dividing line of the adjacent display partitions, and the distance between the preset area Y0 and the dividing line is less than or equal to the preset threshold.

[0189] In some embodiments, the predetermined area Y0 includes a predetermined number of rows of sub-pixels on one side of the boundary line that are adjacent to the boundary line, or at least a portion of the predetermined number of rows of sub-pixels.

[0190] In some embodiments, the distances between the preset areas Y0 in adjacent display partitions and the boundary line are equal.

[0191] Optionally, the brightness of the preset area Y0 is equal to the average brightness of the pixels in the preset area Y0.

[0192] Optionally, the areas of the preset regions Y0 in different display partitions are equal. In some embodiments, the shapes of the preset regions Y0 in different display partitions are the same. Figure 7 In the figure, the preset area Y0 is shown as a rectangle as an example.

[0193] The second display partition AA2 includes a first preset area Y1 and a second preset area Y2, the first preset area Y1 is close to the first dividing line J1, and the second preset area Y2 is close to the second dividing line J2; wherein, the first dividing line J1 is the dividing line between the first display partition AA1 and the second display partition AA2, and the second dividing line J2 is the dividing line between the second display partition AA2 and the third display partition AA3; the brightness difference between the first display partition AA1 and the second display partition AA2 is the brightness difference between the preset area in the first display partition AA1 (recorded as the third preset area Y3) and the first preset area Y1; the brightness difference between the second display partition AA2 and the third display partition AA3 is the brightness difference between the preset area in the third display partition AA3 (recorded as the fourth preset area Y4) and the second preset area Y2.

[0194] Specifically, due to voltage drops when signal lines in a display panel transmit signals, the brightness at different locations within the same display partition may vary at the same grayscale and display brightness level. In this embodiment, the second display partition AA2 is configured to include a first preset area Y1 and a second preset area Y2. The brightness difference between the first display partition AA1 and the second display partition AA2 is determined based on the brightness of the first preset area Y1 near the first dividing line J1 and the brightness of the preset area Y0 within the first display partition AA1. Furthermore, the brightness difference between the first display partition AA1 and the second display partition AA2 near the first dividing line J1 is determined. This ensures that when brightness compensation is subsequently performed using the final display data of the first display partition AA1 determined based on this brightness difference, the brightness difference between the first display partition AA1 and the second display partition AA2 at the first dividing line J1 is reduced, thereby improving the display quality. Similarly, based on the brightness of the second preset area Y2 near the second dividing line J2 and the brightness of the preset area Y0 in the third display area AA3, the brightness difference between the third display area AA3 and the second display area AA2 is determined, and then the brightness difference between the third display area AA3 and the second display area AA2 near the second dividing line J2 is determined, so that when the final display data of the third display area AA3 determined according to the brightness difference is subsequently used for brightness compensation, the brightness difference between the third display area AA3 and the second display area AA2 at the position of the second dividing line J2 is reduced, thereby improving the display effect.

[0195] Optionally, the display data determination method of the display module also includes: determining the final display data corresponding to other gray levels of the display partition to be compensated at the preset display brightness level based on the final display data corresponding to the preset gray level of the display partition to be compensated, and determining the final display data corresponding to each gray level of the display partition to be compensated at other display brightness levels.

[0196] Specifically, in the above-described embodiment of the present invention, the final display data determined is the final display data corresponding to the display partition to be compensated at a preset grayscale at a preset brightness level. At the preset display brightness level, the final display data corresponding to other grayscales corresponds to the final display data at the preset grayscale. After the final display data corresponding to the preset grayscale at the preset brightness level is determined, the final display data corresponding to the preset grayscale at the preset brightness level can be used as a reference to obtain the final display data corresponding to other grayscales at the preset display brightness level. Similarly, the final display data corresponding to the preset grayscale at the preset brightness level can be used as a reference to obtain the final display data corresponding to each grayscale at other display brightness levels.

[0197] Optionally, the preset display screens include at least two, and different preset display screens correspond to different partition situations, or the partition situations are the same, but the refresh frequencies corresponding to at least one display partition are different; different partition situations include different numbers of display partitions, or the number of display partitions is the same but the positions are different.

[0198] Specifically, each partitioning situation can correspond to at least one preset display screen. If a partitioning situation includes a combination of at least two refresh frequencies, then this partitioning situation can correspond to at least two preset display screens. In this way, the preset display screens cover various partitioning situations and refresh frequency combinations. For each preset display screen, the display data determination method of any embodiment of the present invention is used to determine the final display data corresponding to the preset grayscale of the preset brightness level of the display partition to be compensated, and then when the display panel is subsequently brightness compensated, the corresponding final display data is determined according to the partitioning situation and refresh frequency combination corresponding to the target display screen, so that under screens with different partitioning situations or refresh frequency combinations, the brightness difference can be targetedly improved to enhance the display effect.

[0199] Optionally, after determining the final display data, the display data determination method of the display module further includes: burning and storing the final display data.

[0200] Specifically, after the final display data is determined, the final display data may be burned into a storage module of the display module. For example, the storage module may be a flash memory, so as to be used when the display module is subsequently driven for display.

[0201] In some embodiments, after the final display data is burned and stored, the method further includes: adjusting the final display data in at least one display partition and updating the stored final display data.

[0202] Specifically, in some embodiments, after the final display data is burned, the brightness difference of adjacent display partitions of the display module under the final display data is subjectively judged by the human eye, that is, the subjective visual effect of the human eye is judged. When the subjective visual effect of the human eye determines that the brightness difference of adjacent display partitions is too large, the final display data can be further adjusted, and the final display data that has been burned can be updated to ensure better visual effects under the final display data.

[0203] Based on the above embodiments, optionally, the plurality of display modules include at least some display modules cut from a large plate, and the plurality of display modules are located at different positions of the large plate.

[0204] The display module manufacturing process typically involves subjecting a large panel to a display module manufacturing process and then cutting the panel to obtain multiple display modules. The large panel is larger than the display modules. In this embodiment, the multiple display modules selected are from the same batch, specifically at least some of the display modules obtained by cutting the large panel. The multiple display modules are located at different positions on the large panel. Exemplarily, the display modules are arranged in an array on the large panel, with the multiple display modules located in different rows and / or columns.

[0205] Due to process factors, the display modules at different positions of the large panel may have different characteristics. By setting and selecting multiple modules to cover different positions, it is ensured that the final display data is suitable for display modules at different positions, thereby improving the applicability of the final display data and ensuring that each display module obtained by cutting the large panel can have a good display effect under the final display data.

[0206] Optionally, the preset display brightness level at the maximum grayscale is less than or equal to 120 nit, and / or the preset grayscale is less than or equal to 64 grayscales.

[0207] Specifically, because the human eye is not sensitive to high brightness, in a high-brightness display screen, even if there is a certain brightness difference between different display partitions, the human eye cannot clearly feel it. However, the human eye is extremely sensitive to low brightness. In a low-brightness display screen, the human eye can also clearly perceive a very small brightness difference between different display partitions. Therefore, in this embodiment, the preset display brightness level corresponding to the preset display screen is set to be less than or equal to 120nit at the maximum grayscale, and / or the preset grayscale is less than or equal to 64 grayscales, so that the preset display screen is a display screen with lower brightness, and then according to the display data determination method of the embodiment of the present invention, a relatively accurate final display data corresponding to the display partition to be compensated at the preset grayscale of the preset display brightness level with lower brightness is obtained, so that under the final display data, under the display screen with lower brightness, the brightness difference between different display partitions is small, thereby ensuring the display effect under the low-brightness display screen and improving the visual experience. The final display data under the highlighted display screen can be obtained based on the final display data under the low-brightness display screen. On the one hand, this can improve the brightness difference between different display partitions under the highlighted display screen. On the other hand, even if the final display data of the highlighted display screen obtained based on the final display data under the low-brightness display screen has a certain deviation, it is difficult for the human eye to perceive, and the impact on the display effect is relatively small.

[0208] In some embodiments, the brightness of the preset display brightness level at the maximum grayscale is greater than or equal to 60 nits. Exemplarily, the brightness of the preset display brightness level at the maximum grayscale is equal to 90 nits.

[0209] Optionally, the preset grayscale is greater than or equal to 8 grayscales. In some embodiments, the preset grayscale is equal to 16 grayscales.

[0210] The final display data corresponding to the display partition to be compensated at the preset grayscale of the preset display brightness level is used as a reference. Compared with the final display data corresponding to the display partition to be compensated at other display brightness levels and / or other grayscales, it can further improve the brightness differences between different display partitions in the corresponding display screen. However, since display screens with extremely low brightness are relatively rare in actual use, when selecting the preset display brightness level and preset grayscale corresponding to the preset display screen, if the preset display brightness level and / or the preset grayscale are set too low, the final display data corresponding to the display partition to be compensated at the preset grayscale of the preset display brightness level determined by the display data determination method of the embodiment of the present invention will have a low utilization rate in actual use, resulting in an insignificant improvement in the display effect. In an embodiment of the present invention, by selecting the preset display brightness level and the preset grayscale as above, on the one hand, the preset display screen has a lower display brightness level and a smaller preset grayscale, thereby improving the display effect of the low-brightness display screen; on the other hand, the preset display brightness level and the preset grayscale will not be extremely low, ensuring that the final display data corresponding to the display partition to be compensated under the preset grayscale of the preset display brightness level is highly utilized during the actual use of the display module, thereby significantly improving the display effect.

[0211] The embodiment of the present invention further provides another method for determining display data of a display module. Figure 8 is a flowchart of another method for determining display data of a display module provided by an embodiment of the present invention. In the partition multi-frequency display mode, the display module includes at least two display partitions, and the refresh frequencies of the at least two display partitions are different; Figure 8 , the display data determination method includes:

[0212] S310: Select multiple display modules.

[0213] S320: Determine first display data corresponding to the display partition to be compensated when at least some of the display modules meet the target brightness requirement based on brightness differences between adjacent display partitions at different refresh rates under a preset display screen of the initial driving data of the multiple display modules.

[0214] The display partition to be compensated includes at least one of the display partitions.

[0215] S330 : Determine the public version display data according to the first display data corresponding to the display partitions to be compensated in at least some of the display modules.

[0216] S340 , determining final display data corresponding to the display partition to be compensated according to brightness differences between adjacent display partitions with different refresh frequencies under corresponding public display data of the display partition to be compensated.

[0217] The display data determination method for a display module of this embodiment ensures that, in a partitioned multi-frequency display mode, the brightness difference between adjacent display partitions with different refresh rates in the display partition to be compensated meets the target brightness requirement under the final display data, thereby improving the display quality of the display panel in this partitioned multi-frequency display mode. Furthermore, by determining the public display data, debugging time can be reduced. Furthermore, by dividing the first display data into multiple levels, it is easier to find the public display data corresponding to multiple display modules, thereby improving the efficiency of determining the public display data and further enhancing the efficiency of the display data determination method.

[0218] Optionally, S320 includes: adjusting the initial driving data corresponding to the display partitions to be compensated in at least some of the display modules based on the brightness differences of adjacent display partitions with different refresh frequencies under the preset display screen of the initial driving data of multiple display modules, so that the brightness differences of adjacent display partitions with different refresh frequencies under the adjusted driving data of at least some of the display modules meet the target brightness requirements; using the adjusted driving data or compensation data as the first display data corresponding to the display partition to be compensated; wherein the compensation data is used to compensate the initial driving data to obtain the adjusted driving data.

[0219] In some embodiments, the above step S320 is performed for each display module among the selected display modules.

[0220] In other embodiments, after S310 and before S320, it also includes: for each display module of the selected multiple display modules, determining whether the initial driving data needs to be adjusted based on the brightness difference of adjacent display partitions with different refresh frequencies under the preset display screen of the initial driving data of the display module.

[0221] If yes, then S320 is executed. If no, then the initial driving data corresponding to the display module is not adjusted.

[0222] Exemplarily, for any display module among multiple display modules, if the brightness difference between adjacent display partitions with different refresh frequencies of the display module meets the target brightness requirement under the preset display screen of the initial driving data, it is determined that the initial driving data does not need to be adjusted; if the brightness difference between adjacent display partitions with different refresh frequencies of the display module does not meet the target brightness requirement under the preset display screen of the initial driving data, it is determined that the initial driving data needs to be adjusted.

[0223] Optionally, S330 includes dividing the first display data corresponding to the display partition to be compensated in at least some of the display modules into multiple levels based on the first display data corresponding to the same display partition to be compensated; and determining the level of the first display data corresponding to the display module based on the brightness difference between adjacent display partitions at different refresh rates under the first display data of the display partition to be compensated in the display module under the multiple levels of the first display data. By dividing the first display data into multiple levels, it is easier to find the public display data corresponding to multiple display modules, which can improve the efficiency of determining the public display data and further improve the efficiency of the display data determination method.

[0224] Optionally, S340 includes determining the public display data corresponding to the display partition to be compensated as final display data if the brightness difference between adjacent display partitions with different refresh rates under the public display data meets the target brightness requirement; and performing brightness adjustment on the display partition to be compensated to determine final display data that meets the target brightness requirement if the brightness difference between adjacent display partitions with different refresh rates under the public display data does not meet the target brightness requirement. The method for performing brightness adjustment on the display partition to be compensated can be referred to the above-mentioned embodiment of the present invention and will not be described in detail here.

[0225] The embodiment of the present invention also provides a brightness compensation method for a display module. Figure 9 This is a flow chart of a brightness compensation method for a display module provided by an embodiment of the present invention, with reference to Figure 9 , the brightness compensation method of the display module includes:

[0226] S410 , in the partitioned multi-frequency display mode, determining final display data corresponding to the display partitions under the target display screen according to the partitioning status of the display module under the target display screen and the refresh frequencies corresponding to the display partitions.

[0227] Specifically, in an embodiment of the present invention, under a preset display screen, the final display data corresponding to the display partition to be compensated is determined. In this step, the final display data corresponding to the partition to be displayed under the preset display screen, which has the same partitioning situation of the display module under the target display screen and the same refresh frequency combination, can be determined as the final display data corresponding to the partition to be compensated under the target display screen. Among them, the refresh frequency combination includes the refresh frequency corresponding to each display partition. That is, under the preset display screen with the same partitioning situation of the display module of the target display screen and the same refresh frequency corresponding to the display partition, the final display data corresponding to the display partition under the target display screen is determined as the final display data of the corresponding display partition under the target display screen, thereby ensuring that the brightness of the target display screen is accurately compensated and improving the display effect.

[0228] Optionally, the final display data of the display partition includes final display data corresponding to multiple grayscales of multiple display brightness levels; before the final display data corresponding to the display partition under a preset display screen with the same partitioning situation of the display module of the target display screen and the refresh frequency corresponding to the display partition are determined as the final display data of the corresponding display partition under the target display screen, it also includes: determining the display partition where the sub-pixel is located according to the position of the sub-pixel in the display module.

[0229] Optionally, the display partition where the sub-pixel is located is determined according to the position coordinates of the sub-pixel in the display module, for example, the display partition where the sub-pixel is located is determined according to the row number and column number where the sub-pixel is located.

[0230] The final display data corresponding to the display partition under a preset display screen having the same partitioning situation of the display module as the target display screen and the refresh frequency corresponding to the display partition are determined as the final display data of the corresponding display partition under the target display screen, including: according to the target display brightness level under the target display screen and the target display grayscale of the sub-pixel, the final display data of the display partition where the sub-pixel is located is determined at the corresponding grayscale of the corresponding display brightness level.

[0231] Specifically, during the use of the display module after leaving the factory, the display screen is diverse. When the display module displays a display screen, the display brightness level corresponding to each display partition is the same under the same display screen, but under some display screens, the target display grayscale corresponding to different sub-pixels in the same display partition is not exactly the same. In this embodiment, the corresponding final display data is determined for each sub-pixel. Specifically, based on the target display brightness level under the target display screen and the target display grayscale of the sub-pixel, the final display data of the sub-pixel at the corresponding grayscale of the corresponding display brightness level of the display partition can be determined, and then accurate brightness compensation is performed for each sub-pixel to improve the display effect of the display module.

[0232] S420: driving the display module to display according to the final display data.

[0233] In which case, when the final display data is compensation data for the initial drive data, the target drive data can be determined based on the final display data and the initial drive data, and the corresponding target drive data can be provided to the display partition to be compensated of the display module to ensure that the brightness difference of different display partitions is small under the target display screen.

[0234] In the case where the final display data is the driving data obtained after the initial driving data is compensated by the compensation data, the final display data can be used as the target driving data corresponding to the target display screen, and the corresponding target driving data is provided to the display partition to be compensated of the display module to ensure that the brightness difference of different display partitions is small under the target display screen.

[0235] The final display data is determined by the display data determination method of the display module of any embodiment of the present invention.

[0236] The brightness compensation method of the display module according to the embodiment of the present invention drives the display module to display according to the final display data of any embodiment of the present invention, and has the beneficial effects of the display data determination method of the display module according to any of the above embodiments of the present invention.

For example, the steps described in the present invention can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solution of the present invention can be achieved.
