[0018] If the comparison result shows that the difference between the maximum value of the partition current ratio and the minimum value of the partition current ratio is greater than a first preset value, then the operating current of the display panel is reduced by a preset ratio.

[0019] Preferably, the preset ratio is in the range of greater than or equal to three percent and less than or equal to eight percent.

[0020] In an optional embodiment, if the comparison result is that the difference between the maximum value of the partition current ratio and the minimum value of the partition current ratio is less than or equal to the first preset value, the method further includes:

[0021] Continue to obtain the maximum and minimum values ​​of the first ratio among all the partitions, and calculate the difference between the maximum and minimum values ​​of the first ratio; obtain the maximum and minimum values ​​of the second ratio among all the partitions, and calculate the difference between the maximum and minimum values ​​of the second ratio; obtain the maximum and minimum values ​​of the third ratio among all the partitions, and calculate the difference between the maximum and minimum values ​​of the third ratio.

[0023] In an alternative embodiment, it further includes:

[0025] Preferably, when the operating current of the display panel is reduced to the lowest preset ratio of the initial operating current of the display panel, the operating current of the display panel is no longer adjusted.

[0026] In an optional embodiment, when obtaining the partition current ratio corresponding to the partition, there is no operating current in the other partitions of the display panel;

[0043] The specific implementation of the embodiments of this application will be further described below with reference to the accompanying drawings.

[0044] In the OLED field, as OLED display products are used for longer periods, the luminescent materials within them age, leading to brightness degradation. To address this issue, existing technologies typically compensate for OLED display panel brightness based on aging curve models: a small sample of products is taken for laboratory aging verification to obtain an aging curve model. An exemplary aging curve model is shown below. Figure 1 As shown, the X-axis represents the working time, the Y-axis represents the display brightness, line 1 corresponds to the initial display brightness, and lines 2 and 3 represent the aging curve models corresponding to two different areas in the display panel. In the existing technology, the same aging curve model is used to compensate the display brightness of multiple batches of OLED display products. However, due to the differences between different batches of display panels, the accuracy of the existing technology in compensating the display brightness of the display panel is poor and needs to be improved.

[0045] Please see Figure 2 As shown, a data processing method according to an embodiment of this application includes the following steps:

[0046] Step S102. Identify multiple partitions from the display panel.

[0047] For example, a combination of multiple partitions constitutes part or all of the display panel. For instance, the partitions determined from the display panel may be areas at various corners of the display panel, or they may be areas within a circle with the center point of the display panel as the center and a predetermined length as the radius. To obtain a more comprehensive and accurate overall display effect, in one feasible approach, the display panel is divided into multiple partitions, and the display effect of each partition is confirmed separately. In another feasible approach, multiple partitions of equal area are determined in the display panel, thereby ensuring that each partition contains an equal number of pixels. This allows for more accurate and reliable results when comparing the current of each partition in subsequent steps.

[0048] Step S104. For each partition, obtain the partition current ratio corresponding to the partition.

[0049] The display panel contains pixels of various colors, which are the basic units constituting the displayed image. For example, red pixels, green pixels, and blue pixels are used. Different combinations of pixels of different colors are used to display the image. In this embodiment, the display panel contains pixels of preset pixel colors, and image display is achieved by illuminating pixels of different preset pixel colors. For example, the preset pixel colors include a first pixel color, a second pixel color, and a third pixel color. In one feasible approach, when a pixel of the first pixel color, a pixel of the second pixel color, or a pixel of the third pixel color is illuminated individually, the display panel can display a red, green, or blue image. For each partition, when a pixel of the first pixel color, a pixel of the second pixel color, or a pixel of the third pixel color is illuminated individually, that partition can display a red, green, or blue image.

[0050] The luminance of an OLED display panel is directly proportional to its operating current. Therefore, in this embodiment, the operating current is used as the criterion to determine whether there are areas on the OLED display panel with poor compensation effect.

[0051] The partition current ratio represents the ratio between the operating current of the display panel before brightness compensation and the operating current of the display panel after brightness compensation when the pixel of the preset pixel color is lit in the partition. In one feasible approach, when obtaining the partition current ratio for a specific partition, there is no operating current in the other partitions of the display panel. For example, when obtaining the partition current ratio for a specific partition, the other partitions of the display panel do not display any image or display a black image; that is, the operating current of the display panel is considered to be the operating current of only the lit partition, thus providing a data source for subsequent calculation of the partition current ratio for each partition and preventing interference from the current of other partitions in obtaining the partition current ratio for the selected partition, thereby improving data accuracy.

[0052] In one feasible approach, embodiments of this application employ DBI (De-burn-in) technology for brightness compensation of the display panel. In conventional display devices, the DDIC (Display Driver Integrated Circuit) integrates a DBI module for performing brightness compensation on the display panel. See also... Figure 3 The display device shown, when the DBI module is working, obtains compensation parameters for the display panel from the DDIC, including: working time, brightness, grayscale, displayed image content, ambient temperature, and displayed image frame rate. The DBI module processes these compensation parameters, assigning different weights to brightness, grayscale, displayed image content, ambient temperature, and displayed image frame rate according to preset rules. These weights are then used to weight the working time. Based on the weighted working time, the required compensation grayscale value to reach the initial brightness is obtained through an aging curve model. The final compensation value is then output through adjustment of the GAMMA curve. The display panel is then compensated based on this final compensation value. The GAMMA curve describes the non-linear relationship between the input grayscale signal and the output brightness. In one feasible approach, such as... Figure 3 As shown, the DBI module periodically stores compensation parameters and other information into the Flash IC (Flash Integrated Circuit).

[0053] In one feasible approach, a current monitoring module is installed between the display panel and the power supply terminal. For example, a current monitoring module is installed between the display panel and the ELVDD (Electro Luminescent Voltage Driving Device) to obtain the operating current of the display panel. Exemplarily, in a display device, the AP (Application Processor) controls the on / off state of the DBI module and controls the current supplied by the power supply terminal, thereby adjusting the operating current of the display panel.

[0054] In one feasible embodiment of this application, when obtaining the partition current ratio corresponding to a partition, if only the pixels of the first pixel color are lit in the partition, for example, only the red pixels are lit, that is, the partition displays a pure red image, before the DBI module performs display brightness compensation on the partition, the operating current of the display panel is obtained through the current monitoring module. Since the pixels of the other partitions are not lit at this time, the operating current of the display panel is the operating current of the partition. After the DBI module performs display brightness compensation on the partition, the operating current of the display panel is also obtained through the current monitoring module, that is, the operating current of the partition. The ratio of the operating current of the partition before the DBI module performs display brightness compensation on the partition to the operating current of the partition after the display brightness compensation on the partition is taken as the first ratio of the partition. Similarly, when obtaining pixels in a partition that only illuminate the second pixel color, the ratio of the partition's operating current before and after brightness compensation by the DBI module is used as the second ratio for that partition. Similarly, when obtaining pixels in a partition that only illuminate the third pixel color, the ratio of the partition's operating current before and after brightness compensation by the DBI module is used as the third ratio for that partition. Since the operating current of partitions corresponding to different pixel colors varies, the operating current of each pixel color's corresponding partition is statistically analyzed and summarized. This yields a more representative sample of the partition's operating current, used to more accurately determine the differences in aging levels among the various partitions in the display panel. The first, second, and third ratios are processed, and the results are used as the partition current ratios. For example, if the sum of the first ratio, the second ratio, and the third ratio is calculated, the result is the sum of the first ratio, the second ratio, and the third ratio; or, if the average of the first ratio, the second ratio, and the third ratio is calculated, the result is the average of the first ratio, the second ratio, and the third ratio.

[0055] Step S106. Compare the current ratios of each partition and adjust the operating current of the display panel based on the comparison results, so as to drive the display panel based on the adjusted operating current.

[0056] For a display panel after brightness compensation, assuming each zone on the display panel is compensated to its initial brightness, the corresponding zone current ratios should be equal. Based on this theory, by comparing the zone current ratios for each zone, one feasible approach is to obtain the maximum and minimum zone current ratios for each zone on the display panel. Comparing these maximum and minimum ratios allows for a numerical representation of the compensated display effect across each zone, enabling the assessment of differences in display effects. For example, the difference between the maximum and minimum zone current ratios can be obtained, or the quotient of the maximum and minimum ratios can be obtained, or the difference between the square of the maximum and the square of the minimum ratio can be obtained. This allows for a more accurate comparison of the aging differences among the zones on the display panel, and the operating current of the display panel can be adjusted based on the comparison results. If the comparison result shows that the difference between the maximum value and the minimum value of the partition current ratio is greater than the first preset value, for example, if the difference between the maximum value and the minimum value of the partition current ratio is greater than 0.3, then it is determined that there are partitions with large differences in aging degree on the compensated display panel and the compensation effect is poor. At this time, the display panel compensated according to the aging curve model will produce color distortion due to excessive brightness compensation for a partition with a low aging degree or insufficient brightness compensation for a partition with a high aging degree.

[0057] In one feasible embodiment of this application, if the comparison result shows that the difference between the maximum value of the partition current ratio and the minimum value of the partition current ratio is greater than a first preset value, the operating current of the display panel is reduced by a preset ratio, thereby reducing the operating brightness of the display panel. The change in brightness of the display panel before and after reducing the preset ratio is not sensitive to the human eye, thus reducing the impact caused by the difference in the aging degree of each partition. By adjusting the operating current of the display panel based on the comparison result, the display brightness of the display panel is corrected and compensated again, thereby improving the accuracy of the DBI module in compensating for the display brightness of the display panel.

[0058] In one feasible approach, if the comparison result shows that the difference between the maximum and minimum values ​​of the partition current ratios is less than or equal to a first preset value, further judgments are made on the first, second, and third ratios of multiple partitions. Specifically, for all first ratios of all partitions, the maximum and minimum values ​​of the first ratios are selected through sorting or other methods, and the difference between the maximum and minimum values ​​is calculated. Similarly, the maximum and minimum values ​​of the second ratios are selected, and the difference between the maximum and minimum values ​​is calculated; and the maximum and minimum values ​​of the third ratios are selected, and the difference between the maximum and minimum values ​​is calculated. If the difference between the maximum and minimum values ​​of the first ratios is greater than a second preset value, and / or the difference between the maximum and minimum values ​​of the second ratios is greater than a second preset value, and / or the difference between the maximum and minimum values ​​of the third ratios is greater than a second preset value, then the operating current of the display panel is reduced by a preset ratio. In other words, if at least one of the differences between the maximum and minimum values ​​of the first ratio, the second maximum and minimum values ​​of the second ratio, and the third maximum and minimum values ​​of the third ratio is greater than the second preset value, it is determined that there are areas on the compensated display panel with significant differences in aging levels and poor compensation effects. In this case, the operating current of the display panel needs to be lowered by a preset ratio to reduce the impact of differences in aging levels among the various areas. By adjusting the operating current of the display panel based on the comparison results, the display brightness of the display panel is corrected and compensated again, thereby improving the accuracy of the DBI module's compensation for the display panel's brightness. In one feasible approach, the second preset value is 0.15.

[0059] In one feasible approach, the preset ratio ranges from greater than or equal to 3% to less than or equal to 8%. Lowering the preset ratio within this range reduces the sensitivity of the display panel's brightness changes to the human eye, minimizing the impact of differences in aging levels across different zones. In another feasible approach, the preset ratio can be 3%, 4%, 5%, 6%, 7%, or 8%. For example, a preset ratio of 5% means lowering the display panel's operating current by 5%, or adjusting it to 95% of its current operating current. Furthermore, after lowering the display panel's operating current by the preset ratio, brightness compensation is performed again on multiple zones of the display panel, and the results are compared. Based on these comparisons, the display panel's operating current is adjusted. Thus, by continuously adjusting the display panel's operating current and further correcting and compensating for the display panel's brightness, the brightness compensation effect is optimized. In one feasible approach, when the difference between the first maximum value and the first minimum value, the difference between the second maximum value and the second minimum value, and the difference between the third maximum value and the third minimum value are all less than or equal to a second preset value, it is determined that the display brightness compensation of the display panel is relatively accurate, and the display panel is driven by the current adjusted operating current to achieve image display.

[0060] Furthermore, if after reducing the display panel's operating current to the lowest preset proportion of its initial operating current, the comparison result still shows that the difference between the maximum and minimum values ​​of the partition current ratio is greater than the first preset value, or at least one of the differences between the first and first minimum ratios, the second and third maximum and minimum ratios, and the third and third minimum ratios is still greater than the second preset value, then the display panel's operating current will no longer be adjusted to avoid the user perceiving a significant change in display brightness. In this case, it is determined that the display panel can no longer achieve a good compensation effect through display brightness compensation. The lowest preset proportion of the initial operating current is achieved because before the display panel's operating current is reduced to this lowest preset proportion each time, the user's naked eye is not sensitive to changes in brightness and cannot directly perceive the change. Therefore, by reducing the display panel's operating current, the display panel achieves a better display brightness compensation effect. In one feasible approach, the minimum preset ratio is 70%, that is, after the operating current of the display panel is reduced to 70% of the initial operating current of the display panel by adjusting the preset ratio each time, the operating current of the display panel is no longer adjusted.

[0061] As can be seen, the solution of this application determines multiple zones in the display panel. When each zone of the display panel is lit up with a preset pixel color, the current ratio before and after brightness compensation of the display panel is statistically analyzed to obtain the current ratio of each zone. Then, by comparing the current ratios of different zones and adjusting the operating current of the display panel based on the comparison results, the brightness of the display panel is corrected and compensated again. This improves the accuracy of brightness compensation of the display panel, reduces color cast on the display panel, and the brightness of the display panel changes within a range that is not sensitive to the human eye, so it will not be noticed by the user.

[0062] This application also provides a data processing apparatus, see below. Figure 4 As shown, it includes:

[0063] The partitioning module is used to identify multiple partitions from the display panel.

[0064] The acquisition module is used to acquire the partition current ratio for each partition. The partition current ratio represents the ratio between the operating current of the display panel before brightness compensation is performed and the operating current of the display panel after brightness compensation is performed when the pixel of the preset pixel color is lit in the partition.

[0065] The adjustment module is used to compare the current ratio of each partition and adjust the operating current of the display panel based on the comparison results, so as to drive the display panel based on the adjusted operating current.

[0066] In one feasible approach, the preset pixel color includes a first pixel color, a second pixel color, and a third pixel color; the acquisition module is specifically used for:

[0067] The first ratio between the operating current of the partition before and after brightness compensation is performed when only the first pixel color of the partition is lit, the second ratio between the operating current of the partition before and after brightness compensation is performed when only the second pixel color of the partition is lit, and the third ratio between the operating current of the partition before and after brightness compensation is performed when only the third pixel color of the partition is lit.

[0068] The first, second, and third ratios of the partitions are processed, and the processing results are used as the partition current ratios corresponding to the partitions.

[0069] In one feasible approach, the adjustment module, when performing the step of comparing the partition current ratios corresponding to each partition and adjusting the operating current of the display panel based on the comparison results, is specifically used for:

[0070] Compare the current ratios of each zone, and adjust the operating current of the display panel based on the comparison results, including:

[0071] Obtain the maximum and minimum partition current ratios from multiple partitions;

[0072] The maximum and minimum values ​​of the partition current ratios are compared, and the operating current of the display panel is adjusted based on the comparison results.

[0073] In one feasible approach, the adjustment module, when performing the step of adjusting the operating current of the display panel based on the comparison result, is specifically used for:

[0074] If the comparison result shows that the difference between the maximum value and the minimum value of the partition current ratio is greater than the first preset value, the operating current of the display panel will be reduced by the preset ratio.

[0075] For example, if the difference between the maximum and minimum values ​​of the partition current ratio is greater than 0.3, the operating current of the display panel will be reduced by a preset ratio, thereby reducing the brightness of the display panel. The change in brightness of the display panel before and after reducing the preset ratio is not sensitive to the human eye, thus reducing the impact of differences in the aging degree of each partition. By adjusting the operating current of the display panel based on the comparison results, the display brightness of the display panel is corrected and compensated again, thereby improving the accuracy of the display brightness compensation.

[0076] In one feasible approach, if the comparison result shows that the difference between the maximum and minimum values ​​of the partition current ratios is less than or equal to a first preset value, further judgments are made on the first, second, and third ratios of multiple partitions. Specifically, for all first ratios of all partitions, the maximum and minimum values ​​of the first ratios are selected through sorting or other methods, and the difference between the maximum and minimum values ​​is calculated. Similarly, the maximum and minimum values ​​of the second ratios are selected, and the difference between the maximum and minimum values ​​is calculated; and the maximum and minimum values ​​of the third ratios are selected, and the difference between the maximum and minimum values ​​is calculated. If the difference between the maximum and minimum values ​​of the first ratios is greater than a second preset value, and / or the difference between the maximum and minimum values ​​of the second ratios is greater than a second preset value, and / or the difference between the maximum and minimum values ​​of the third ratios is greater than a second preset value, then the operating current of the display panel is reduced by a preset ratio. In other words, if at least one of the differences between the maximum and minimum values ​​of the first ratio, the second maximum and minimum values ​​of the second ratio, and the third maximum and minimum values ​​of the third ratio is greater than the second preset value, it is determined that there are areas on the compensated display panel with significant differences in aging levels and poor compensation effects. In this case, the operating current of the display panel needs to be lowered by a preset ratio to reduce the impact of differences in aging levels among the various areas. By adjusting the operating current of the display panel based on the comparison results, the display brightness of the display panel is corrected and compensated again, thereby improving the accuracy of the display brightness compensation. In one feasible method, the second preset value is 0.15.

[0077] In one feasible approach, the preset ratio ranges from greater than or equal to 3% to less than or equal to 8%. Lowering the preset ratio within this range reduces the sensitivity of the display panel's brightness changes to the human eye, minimizing the impact of differences in aging levels across different zones. Specifically, in another feasible approach, the ratios are 3%, 4%, 5%, 6%, 7%, and 8%. For example, a preset ratio of 5% means lowering the display panel's operating current by 5%, or adjusting it to 95% of its current operating current. Further, after lowering the display panel's operating current by the preset ratio, brightness compensation is performed again on multiple zones of the display panel, and the results are compared. Based on these comparisons, the display panel's operating current is adjusted. Thus, by continuously adjusting the display panel's operating current and further correcting and compensating for the display panel's brightness, the brightness compensation effect is optimized. In one feasible approach, when the difference between the first maximum value and the first minimum value, the difference between the second maximum value and the second minimum value, and the difference between the third maximum value and the third minimum value are all less than or equal to a second preset value, it is determined that the display brightness compensation of the display panel is relatively accurate, and the display panel is driven by the current adjusted operating current to achieve image display.

[0078] Furthermore, if after reducing the display panel's operating current to the lowest preset proportion of its initial operating current, the comparison result still shows that the difference between the maximum and minimum values ​​of the partition current ratio is greater than the first preset value, or at least one of the differences between the first and first minimum ratios, the second and third maximum and minimum ratios, and the third and third minimum ratios is still greater than the second preset value, then the display panel's operating current will no longer be adjusted to avoid the user perceiving a significant change in display brightness. In this case, it is determined that the display panel can no longer achieve a good compensation effect through display brightness compensation. The lowest preset proportion of the initial operating current is achieved because before the display panel's operating current is reduced to this lowest preset proportion each time, the user's naked eye is not sensitive to changes in brightness and cannot directly perceive the change. Therefore, by reducing the display panel's operating current, the display panel achieves a better display brightness compensation effect. In one feasible approach, the minimum preset ratio is 70%, that is, after the operating current of the display panel is reduced to 70% of the initial operating current of the display panel by adjusting the preset ratio each time, the operating current of the display panel is no longer adjusted.
