[0041] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present application should fall within the scope of protection of the embodiments of the present application.

[0042] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms of "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used in the embodiments of the present application refers to and includes any or all possible combinations of one or more associated listed items.

[0043] The specific implementation of the embodiment of the present application is further explained below in conjunction with the accompanying drawings of the embodiment of the present application.

[0044] In the field of OLED, as the use time of OLED display products increases, the luminous materials in the OLED display products age as the working time increases, resulting in the problem of brightness decay in OLED display products. In order to solve the above problem, the prior art usually performs display brightness compensation on the display panel of OLED display products based on an aging curve model: a small number of products are taken as samples for laboratory aging verification to obtain an aging curve model. An exemplary aging curve model is as follows: Figure 1 As shown, wherein the X-axis is the working time, the Y-axis is the display brightness, line 1 corresponds to the initial display brightness, and lines 2 and 3 are aging curve models corresponding to two different areas in the display panel. In the prior art, display brightness compensation is performed on multiple batches of OLED display products based on the same aging curve model. However, due to the differences between different batches of display panels, the accuracy of display brightness compensation for display panels in the prior art is poor and needs to be improved.

[0045] See also Figure 2 As shown, a data processing method in an embodiment of the present application includes the following steps:

[0046] Step S102: Determine a plurality of partitions from the display panel.

[0047] Exemplarily, a combination of multiple partitions constitutes a partial area or the entire area of ​​the display panel. For example, the multiple partitions determined from the display panel are areas at various corner positions in the display panel, or the multiple partitions determined from the display panel are areas in a circle with a center point of the display panel as the center and a preset length as the radius in the display panel. In order to obtain a more comprehensive and accurate overall display effect of the display panel, in a feasible manner, the display panel is divided into multiple partitions, and the display effect of each partition is confirmed separately. In a feasible manner, multiple partitions of equal area are determined in the display panel, so that the number of pixels contained in each partition is equal, so that when the current of each partition is compared in the subsequent steps, the result obtained is more accurate and reliable.

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

[0049] The pixels of various colors contained in the display panel are the basic units constituting the display image of the display panel, for example, red pixels, green pixels and blue pixels, and the display image is displayed by different combinations of pixels of different colors. In an embodiment of the present application, the display panel includes pixels of preset pixel colors, and image display is achieved by lighting up 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 a feasible manner, when the pixels of the first pixel color, the pixels of the second pixel color or the pixels of the third pixel color are lit separately, the display panel can display a red picture, a green picture or a blue picture. For each partition, when the pixels of the first pixel color, the pixels of the second pixel color or the pixels of the third pixel color are lit separately, the partition can display a red picture, a green picture or a blue picture.

[0050] The luminous brightness of the OLED display panel is proportional to the operating current. Therefore, the embodiment of the present application uses the operating current as a judgment basis to determine whether there is an area on the OLED display panel with a poor compensation effect.

[0051] Among them, the partition current ratio corresponding to the partition represents the ratio between the operating current of the display panel before the display panel is compensated for display brightness and the operating current of the display panel after the display panel is compensated for display brightness when the partition lights up the pixel of the preset pixel color. In one feasible way, when obtaining the partition current ratio corresponding to a partition, there is no operating current in the remaining partitions on the display panel. For example, when obtaining the partition current ratio corresponding to a partition, the remaining partitions on the display panel do not display the picture, or display a black picture; that is, at this time, the operating current of the display panel is regarded as the operating current of the partition that is only lit, thereby providing a data source for the subsequent calculation of the partition current ratio of each partition, and preventing the current of the remaining partitions from interfering with the acquisition of the partition current ratio corresponding to the selected partition, thereby improving the accuracy of the data.

[0052] In one feasible manner, the embodiment of the present application uses DBI (De-burn-in, brightness attenuation compensation) technology to compensate the display brightness of the display panel. In a conventional display device, a DBI module is integrated in a DDIC (Display Driver Integrated Circuit, display driver chip) to compensate the display brightness of the display panel in the display device. Figure 3 In the display device shown, when the DBI module is working, the DDIC obtains the compensation parameters of the display panel Panel, including: working time, brightness, grayscale, display image content, ambient temperature and display image frame rate, etc. The compensation parameters are processed in the DBI module, and the brightness, grayscale, display image content, ambient temperature and display image frame rate are processed into different weights according to preset rules. The working time is weighted using the weights, and the compensation grayscale value required to compensate to the initial brightness is obtained through the aging curve model based on the weighted working time. The final compensation value is output through the adjustment of the GAMMA curve. The display panel is compensated according to the final compensation value. Among them, the GAMMA curve describes the nonlinear relationship between the input grayscale signal and the output brightness. In one feasible method, such as Figure 3 As shown, the DBI module regularly stores the compensation parameters and other contents in a Flash IC (Flash Integrated Circuit).

[0053] In one feasible manner, a current monitoring module is provided between the display panel and the power supply end, for example, a current monitoring module is provided between the display panel and ELVDD (Electro Luminescent Voltage Driving Device), so as to obtain the operating current of the display panel. For example, in a display device, an AP (Application Processor) controls the opening and closing of a DBI module, and the AP controls the current supplied by the power supply end, so as to adjust the operating current of the display panel.

[0054] In an embodiment of the present application, in a feasible method, when obtaining the partition current ratio corresponding to the partition, in the partition, only pixels of the first pixel color are lit, for example, only red pixels are lit, that is, the partition displays a red pure color picture, 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, and since the pixels of the remaining 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 working current of the partition; the ratio of the working current of the partition before the DBI module performs display brightness compensation on the partition to the working current of the partition after the display brightness compensation is performed on the partition is used as the first ratio of the partition. Similarly, when obtaining pixels of the partition that only light up the second pixel color, the DBI module uses the ratio of the working current of the partition before display brightness compensation for the partition to the working current of the partition after display brightness compensation for the partition as the second ratio of the partition; and when obtaining pixels of the partition that only light up the third pixel color, the DBI module uses the ratio of the working current of the partition before display brightness compensation for the partition to the working current of the partition after display brightness compensation for the partition as the third ratio of the partition. Since the working currents of the partitions corresponding to different pixel colors are different, the working currents of the partitions corresponding to each pixel color are counted and summarized separately, thereby obtaining the working currents of more representative partitions, which are used to make a more accurate judgment on the differences in the degree of aging of each partition in the display panel. Process the first ratio, the second ratio and the third ratio, and use the processing results as the partition current ratios of the partitions. For example, the sum of the first ratio, the second ratio and the third ratio is calculated, and the processing result is the sum of the first ratio, the second ratio and the third ratio; or the average of the first ratio, the second ratio and the third ratio is calculated, and the processing result is the average of the first ratio, the second ratio and the third ratio.

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

[0056] For the display panel after display brightness compensation, when each partition on the display panel is compensated to the initial brightness, the partition current ratios corresponding to each partition on the display panel should be equal. Based on the above theory, the partition current ratios corresponding to each partition are compared. In a feasible way, the maximum partition current ratio and the minimum partition current ratio in the partition current ratios of each partition on the display panel are obtained, and the maximum partition current ratio and the minimum partition current ratio are compared. With the help of the maximum partition current ratio and the minimum partition current ratio, the display effect of each partition on the display panel after compensation is intuitively presented in a numerical manner, which is used to judge the difference between the display effects of each partition on the display panel after compensation, for example, the difference between the maximum partition current ratio and the minimum partition current ratio is obtained, or the quotient between the maximum partition current ratio and the minimum partition current ratio is obtained, or the difference between the square value of the maximum partition current ratio and the square value of the minimum partition current ratio is obtained, so as to make a more accurate comparison of the difference in the degree of aging of each partition in the display panel, and adjust the working current of the display panel based on the comparison result. 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 greater than the first preset value, for example, 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 greater than 0.3, then it is determined that there are partitions with large differences in aging degrees and poor compensation effects on the compensated display panel. At this time, the display panel compensated according to the aging curve model will produce color cast because the brightness of a partition with a lower aging degree is compensated too much, or because the brightness of a partition with a higher aging degree is compensated too little.

[0057] In one feasible manner, in an embodiment of the present application, 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 greater than a first preset value, the operating current of the display panel is adjusted down by a preset ratio, thereby reducing the operating brightness of the display panel. The brightness change of the display panel before and after the preset ratio is lowered is not sensitive to the human eye, thereby reducing the impact caused by the difference in 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 the display brightness of the display panel.

[0058] In a feasible manner, 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 first ratio, the second ratio and the third ratio of the multiple partitions are further judged. Specifically, for all the first ratios of all the partitions, the maximum value of the first ratio and the minimum value of the first ratio are selected from all the first ratios by sorting, etc., and the difference between the maximum value of the first ratio and the minimum value of the first ratio is calculated. Similarly, the maximum value of the second ratio and the minimum value of the second ratio are selected from all the second ratios, and the difference between the maximum value of the second ratio and the minimum value of the second ratio is calculated, and the maximum value of the third ratio and the minimum value of the third ratio are selected from all the third ratios, and the difference between the maximum value of the third ratio and the minimum value of the third ratio is calculated. If the difference between the maximum value of the first ratio and the minimum value of the first ratio is greater than the second preset value, and / or the difference between the maximum value of the second ratio and the minimum value of the second ratio is greater than the second preset value, and / or the difference between the maximum value of the third ratio and the minimum value of the third ratio is greater than the second preset value, then the working current of the display panel is adjusted down by a preset ratio. That is, when at least one of the difference between the first ratio maximum and the first ratio minimum, the difference between the second ratio maximum and the second ratio minimum, and the difference between the third ratio maximum and the third ratio minimum is greater than the second preset value, it is also determined that there are partitions with large differences in aging degrees and poor compensation effects on the compensated display panel, and it is necessary to reduce the operating current of the display panel by a preset ratio, thereby reducing the impact caused by the differences in aging degrees of each partition, and 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's compensation of the display brightness of the display panel. In a feasible manner, the second preset value is 0.15.

[0059] In a feasible manner, the range of the preset ratio is greater than or equal to 3% and less than or equal to 8%. When the preset ratio within the range is lowered, the brightness change of the display panel is not sensitive to the human eye, reducing the impact caused by the difference in the degree of aging of each partition. In a feasible manner, the preset ratio can be 3%, 4%, 5%, 6%, 7%, 8%, for example, 5%, then the preset ratio is lowered to achieve the working current of the display panel by 5%, that is, the working current of the display panel is adjusted to 95% of the current working current. Further, after the working current of the display panel is lowered by the preset ratio, the display brightness compensation is performed on multiple partitions of the display panel again and the comparison results are obtained, and the working current of the display panel is adjusted based on the comparison results. Thus, by continuously adjusting the working current of the display panel and correcting and compensating the display brightness of the display panel again, the display brightness compensation effect of the display panel is optimized. In one feasible method, when the difference between the first ratio maximum value and the first ratio minimum value, the difference between the second ratio maximum value and the second ratio minimum value, and the difference between the third ratio maximum value and the third ratio minimum value are all less than or equal to the second preset value, it is determined that the display brightness compensation of the display panel is more accurate, and the display panel is driven by the current adjusted working current to achieve picture display.

[0060] Furthermore, if after the working current of the display panel is adjusted down to the lowest preset ratio of the initial working current of the display panel, the comparison result is still that the difference between the maximum value of the partition current ratio and the minimum value of the partition current ratio is greater than the first preset value, or, at least one of the difference between the first ratio maximum value and the first ratio minimum value, the difference between the second ratio maximum value and the second ratio minimum value, and the difference between the third ratio maximum value and the third ratio minimum value is still greater than the second preset value, the working current of the display panel is no longer adjusted to prevent the user from feeling the obvious change in display brightness. At this time, it is determined that the display panel can no longer achieve a better compensation effect by performing display brightness compensation. Among them, the lowest preset ratio of the initial working current is realized as follows: before the working current of the display panel is adjusted down to the lowest preset ratio of the initial working current of the display panel in a manner of lowering the preset ratio each time, the user's naked eye is not sensitive to the change in brightness and cannot directly feel the change in brightness. Therefore, by reducing the working current of the display panel, the display panel obtains a better display brightness compensation effect. In one feasible manner, the minimum preset ratio is implemented as 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 reducing the preset ratio each time, the operating current of the display panel is no longer adjusted.

[0061] It can be seen that through the scheme of the embodiment of the present application, multiple partitions are determined from the display panel, and when the pixels of the preset pixel color are respectively lit in each partition of the display panel, the current ratios before and after the display brightness compensation of the display panel are statistically calculated to obtain the partition current ratios corresponding to each partition, and then by comparing the partition current ratios of different partitions and adjusting the display panel working current based on the comparison result, the display brightness of the display panel is corrected and compensated again, thereby improving the accuracy of the display brightness compensation of the display panel, reducing the color cast on the display panel, and the brightness of the display panel changes within a range that the human eye is not sensitive to and will not be noticed by the user.

[0062] The present application also provides a data processing device, see Figure 4 As shown, including:

[0063] A partition module is used to determine multiple partitions from the display panel.

[0064] An acquisition module is used to acquire, for each partition, a partition current ratio corresponding to the partition; the partition current ratio represents the ratio between the operating current of the display panel before display brightness compensation is performed on the display panel and the operating current of the display panel after display brightness compensation is performed on the display panel when the partition lights up pixels of a preset pixel color;

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

[0066] In a feasible manner, the preset pixel colors include a first pixel color, a second pixel color, and a third pixel color; the acquisition module is specifically used to:

[0067] Obtaining a first ratio between the operating current of the partition before display brightness compensation is performed and the operating current of the partition after display brightness compensation is performed when only pixels of the first pixel color are lit in the partition, a second ratio between the operating current of the partition before display brightness compensation is performed and the operating current of the partition after display brightness compensation is performed when only pixels of the second pixel color are lit in the partition, and a third ratio between the operating current of the partition before display brightness compensation is performed and the operating current of the partition after display brightness compensation is performed when only pixels of the third pixel color are lit in the partition;

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

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

[0070] Comparing the partition current ratios corresponding to the partitions, and adjusting the operating current of the display panel based on the comparison result, including:

[0071] Obtaining a maximum partition current ratio value and a minimum partition current ratio value among partition current ratio values ​​of multiple partitions;

[0072] The maximum partition current ratio and the minimum partition current ratio are compared, and the operating current of the display panel is adjusted based on the comparison result.

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

[0074] 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 greater than the first preset value, the working current of the display panel is reduced by a preset proportion.

[0075] For example, 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 greater than 0.3, the operating current of the display panel is lowered by a preset ratio, thereby reducing the operating brightness of the display panel. The brightness change of the display panel before and after the preset ratio is lowered is not sensitive to the human eye, thereby reducing the impact of the difference in the degree of aging 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 display brightness compensation of the display panel.

[0076] In a feasible manner, 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 first ratio, the second ratio and the third ratio of the multiple partitions are further judged. Specifically, for all the first ratios of all the partitions, the maximum value of the first ratio and the minimum value of the first ratio are selected from all the first ratios by sorting, etc., and the difference between the maximum value of the first ratio and the minimum value of the first ratio is calculated. Similarly, the maximum value of the second ratio and the minimum value of the second ratio are selected from all the second ratios, and the difference between the maximum value of the second ratio and the minimum value of the second ratio is calculated, and the maximum value of the third ratio and the minimum value of the third ratio are selected from all the third ratios, and the difference between the maximum value of the third ratio and the minimum value of the third ratio is calculated. If the difference between the maximum value of the first ratio and the minimum value of the first ratio is greater than the second preset value, and / or the difference between the maximum value of the second ratio and the minimum value of the second ratio is greater than the second preset value, and / or the difference between the maximum value of the third ratio and the minimum value of the third ratio is greater than the second preset value, then the working current of the display panel is adjusted down by a preset ratio. That is, when at least one of the difference between the first ratio maximum and the first ratio minimum, the difference between the second ratio maximum and the second ratio minimum, and the difference between the third ratio maximum and the third ratio minimum is greater than the second preset value, it is also determined that there are partitions with large differences in aging degrees and poor compensation effects on the compensated display panel, and it is necessary to reduce the operating current of the display panel by a preset ratio, thereby reducing the impact caused by the differences in aging degrees of each partition, and 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 display brightness compensation of the display panel. In a feasible manner, the second preset value is 0.15.

[0077] In a feasible manner, the range of the preset ratio is greater than or equal to 3% and less than or equal to 8%. When the preset ratio within the range is lowered, the brightness change of the display panel is not sensitive to the human eye, reducing the impact caused by the difference in the degree of aging of each partition. In a feasible manner, specifically 3%, 4%, 5%, 6%, 7%, 8%, for example, the preset ratio is 5%, then the preset ratio is lowered to achieve the working current of the display panel by 5%, that is, the working current of the display panel is adjusted to 95% of the current working current. Furthermore, after the working current of the display panel is lowered by the preset ratio, the display brightness compensation is performed again on multiple partitions of the display panel and the comparison results are obtained, and the working current of the display panel is adjusted based on the comparison results. Thus, by continuously adjusting the working current of the display panel and correcting and compensating the display brightness of the display panel again, the display brightness compensation effect of the display panel is optimized. In one feasible method, when the difference between the first ratio maximum value and the first ratio minimum value, the difference between the second ratio maximum value and the second ratio minimum value, and the difference between the third ratio maximum value and the third ratio minimum value are all less than or equal to the second preset value, it is determined that the display brightness compensation of the display panel is more accurate, and the display panel is driven by the current adjusted working current to achieve picture display.

[0078] Furthermore, if after the working current of the display panel is adjusted down to the lowest preset ratio of the initial working current of the display panel, the comparison result is still that the difference between the maximum value of the partition current ratio and the minimum value of the partition current ratio is greater than the first preset value, or, at least one of the difference between the first ratio maximum value and the first ratio minimum value, the difference between the second ratio maximum value and the second ratio minimum value, and the difference between the third ratio maximum value and the third ratio minimum value is still greater than the second preset value, the working current of the display panel is no longer adjusted to prevent the user from feeling the obvious change in display brightness. At this time, it is determined that the display panel can no longer achieve a better compensation effect by performing display brightness compensation. Among them, the lowest preset ratio of the initial working current is realized as follows: before the working current of the display panel is adjusted down to the lowest preset ratio of the initial working current of the display panel in a manner of lowering the preset ratio each time, the user's naked eye is not sensitive to the change in brightness and cannot directly feel the change in brightness. Therefore, by reducing the working current of the display panel, the display panel obtains a better display brightness compensation effect. In one feasible manner, the minimum preset ratio is implemented as 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 reducing the preset ratio each time, the operating current of the display panel is no longer adjusted.
