[0008] Based on the initial compensation value and the compensation weight value, the luminance parameters of the M target pixel units in the second pixel row are compensated to obtain the compensated luminance parameters of the M target pixel units; M is a positive integer.

[0009] Based on the same inventive concept, in a second aspect, embodiments of this application provide a compensation device for a display panel. The display panel includes adjacent first pixel rows and second pixel rows, and in a data scanning cycle, the first pixel rows are scanned before the second pixel rows; the difference between the sum of the luminance parameters of multiple pixel units in the first pixel row and the sum of the luminance parameters of multiple pixel units in the second pixel row is greater than a preset threshold; the compensation device for the display panel includes:

[0010] The first acquisition module is used to acquire the initial compensation value of the pixel unit in the second pixel row; the initial compensation value is obtained based on the luminance parameter of the pixel unit in the first pixel row and the luminance parameter of the pixel unit in the second pixel row.

[0011] The first determining module is used to determine the target area where the second pixel row is located based on the luminance parameters of the pixel units in the second pixel row.

[0012] The second determining module is used to determine the compensation weight value of the pixel unit in the second pixel row based on the correspondence between the target area and the compensation weight value.

[0013] The first compensation module is used to compensate the luminance parameters of M target pixel units in the second pixel row based on the initial compensation value and the compensation weight value, so as to obtain the compensated luminance parameters of the M target pixel units; M is a positive integer.

[0014] Based on the same inventive concept, in a third aspect, embodiments of this application provide an electronic device, which includes: a processor, a memory, and a computer program stored in the memory and executable on the processor.

[0015] Based on the same inventive concept, in a fourth aspect, embodiments of this application provide a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the compensation method for the display panel as provided in the first aspect.

[0016] As described above, the present application provides a compensation method, apparatus, device, and storage medium for a display panel. The second pixel row is a pixel row with linear crosstalk. Specifically, when compensating for the linear crosstalk in the second pixel row, the initial compensation value of the pixel unit in the second pixel row is obtained, and the target area of ​​the second pixel row is determined based on the luminance parameters of the pixel unit in the second pixel row. Then, based on the correspondence between the target area and the compensation weight value, the compensation weight value of the pixel unit in the second pixel row is determined. Finally, based on the initial compensation value and the compensation weight value, the luminance parameters of the target pixel unit in the second pixel row are compensated to obtain the compensated luminance parameters of the target pixel unit.

[0017] Compared to existing technologies, the compensation method, apparatus, device, and storage medium for a display panel according to embodiments of this application consider that the degree of line crosstalk caused by the same DATA voltage difference varies at different locations on the display panel. If the same DATA voltage difference is compensated to the same degree, the line crosstalk compensation effect will be poor. Therefore, embodiments of this application determine the target area where the second pixel row is located, and then determine the compensation weight value of the pixel unit in the second pixel row according to the correspondence between the target area and the compensation weight value. In this way, by introducing a compensation weight value related to the target area where the second pixel row is located, differential compensation can be performed on the second pixel row at different locations to improve the line crosstalk compensation effect, thereby effectively and sufficiently improving the problem of uneven display brightness on the display panel, and thus effectively improving the display effect of the display panel.

[0031] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0033] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0034] In the embodiments of this application, the term "electrical connection" can refer to a direct electrical connection between two components, or it can refer to an electrical connection between two components via one or more other components.

[0035] Various modifications and variations can be made to this application without departing from its spirit or scope, which will be apparent to those skilled in the art. Therefore, this application is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the embodiments provided in this application can be combined with each other without contradiction.

[0036] Before describing the technical solutions provided in the embodiments of this application, in order to facilitate understanding of the embodiments of this application, this application first specifically explains the problems existing in the related technologies:

[0037] As mentioned above, the inventors of this application have discovered that the related technology suffers from display panel crosstalk. In the field of display technology, due to the influence of wiring process design and other factors in OLED display modules, coupling interference between the display data voltage (DATA voltage) and the power supply voltage (PVDD) is unavoidable. This interference causes line crosstalk to occur when the OLED display module displays certain images.

[0038] Please see details. Figure 1 , Figure 1 This is a schematic diagram illustrating the principle of line crosstalk in a display panel according to an embodiment of this application. For example... Figure 1 As shown, when the DATA voltage changes at the transition between the white and black screens on the display panel, the parasitic capacitance between PVDD and DATA will simultaneously cause the PVDD voltage to fluctuate. If the DATA voltage increases, the PVDD voltage will increase; if the DATA voltage decreases, the PVDD voltage will decrease.

[0039] For details on line crosstalk linearity, please refer to [link / reference]. Figure 2 as well as Figure 3 . Figure 2 This is a schematic diagram illustrating the crosstalk behavior of a display panel according to an embodiment of this application, as shown below. Figure 2 As shown, when the PVDD at the top edge of the black screen jumps upwards, the voltage difference between the DATA write line and PVDD increases, resulting in a bright line at the boundary between the black and white screens. Conversely, when the PVDD at the bottom edge of the black screen jumps downwards, the voltage difference between the DATA write line and PVDD decreases, resulting in a dark line at the boundary between the black and white screens. The display effects of the bright and dark lines on the display panel are as follows: Figure 2 As shown, it should be noted that, to facilitate observation of the bright and dark lines at the boundary between the black and white images, therefore... Figure 2 The white screen in the image is represented by gray.

[0040] Figure 3 This is a schematic diagram illustrating the crosstalk behavior of another display panel provided in an embodiment of this application. For example... Figure 3 As shown, when the PVDD at the top edge of the white screen jumps downwards, the voltage difference between the DATA write line and PVDD decreases, and a dark line appears at the boundary between the black and white screens. When the PVDD at the bottom edge of the white screen jumps upwards, the voltage difference between the DATA write line and PVDD increases, and a bright line appears at the boundary between the black and white screens. The display effect of the bright and dark lines on the display panel in this situation is as follows: Figure 3 As shown.

[0041] To improve the poor display quality of display panels caused by line crosstalk, existing technologies involve determining the DATA voltage corresponding to bright and dark lines, calculating the difference between the two DATA voltages, determining the compensation intensity for bright and dark lines based on the voltage difference, and then applying compensation accordingly. However, this compensation method still fails to effectively reduce line crosstalk in display panels, resulting in unsatisfactory compensation. Therefore, how to effectively improve the line crosstalk phenomenon that easily occurs in OLED display modules when displaying images has become an urgent technical problem to be solved.

[0042] In view of the inventors' above-mentioned research findings, and in order to solve the problems of the prior art, embodiments of this application provide a compensation method, apparatus, device, and storage medium for a display panel. It should be noted that the embodiments provided in this application are not intended to limit the scope of this application.

[0043] The compensation method for the display panel provided in the embodiments of this application will be described below.

[0044] Please see first. Figure 4 , Figure 4 This is a schematic diagram of a display panel provided in an embodiment of this application. The display panel can be AMOLED, OLED, or others. Those skilled in the art should understand that in other implementations of this application, the display panel can also be a micro-light-emitting diode display panel, a quantum dot display panel, etc.

[0045] like Figure 4 As shown, the display panel may include adjacent first pixel rows 10 and second pixel rows 20, which may be arranged at intervals in a first direction Y. Each pixel row may include multiple pixel units extending along a second direction X. In one data scan cycle, the first pixel row 10 is scanned before the second pixel row 20. It should be added that, in the field of display panel technology, the display panel includes multiple rows of pixel circuits. Within a display frame, the scan signals used to control data writing typically scan each row of pixel circuits sequentially. Within the same display frame, the scanning order of the first pixel row 10 precedes that of the second pixel row 20.

[0046] The difference between the sum of the luminance parameters of multiple pixel units in the first pixel row 10 and the sum of the luminance parameters of multiple pixel units in the second pixel row is greater than the target threshold. The luminance parameters here can specifically be, for example, data voltage (Vdata), gamma register value, grayscale value to be displayed, and brightness value to be displayed.

[0047] For example, before displaying a frame, it is usually necessary to obtain the image parameters (such as grayscale values ​​or brightness values) of the image to be displayed, and then determine the actual required luminous brightness parameters of each pixel unit in each pixel row of the display panel based on the image parameters. Based on this, the first pixel row 10 and the second pixel row 20 can be determined after obtaining the image parameters of the image to be displayed and during the time period when the image to be displayed is actually displayed.

[0048] Taking the luminance parameter as the data voltage Vdata as an example, if the difference between the sum of the luminance parameters of multiple pixel units in the first pixel row 10 and the sum of the luminance parameters of multiple pixel units in the second pixel row 20 is greater than the target threshold, it can be interpreted as the difference between the sum of the data voltages Vdata of multiple pixel units in the first pixel row 10 and the sum of the data voltages Vdata of multiple pixel units in the second pixel row 20 being greater than the target threshold. In this case, it indicates that when scanning from the first pixel row to the second pixel row, the data voltage Vdata of the second pixel row changes compared to the first pixel row, and the second pixel row is the pixel row where line crosstalk (bright lines, dark lines) is located.

[0049] It should be added that the above target threshold can be set in combination with relevant experience in line crosstalk or actual debugging needs, and this application does not impose specific restrictions on it.

[0050] Figure 5 A flowchart illustrating a compensation method for a display panel according to an embodiment of this application is shown. Figure 5 As shown, the compensation method for this display panel may include the following steps:

[0051] S510. Obtain the initial compensation value of the pixel unit in the second pixel row; the initial compensation value is obtained based on the luminance parameter of the pixel unit in the first pixel row and the luminance parameter of the pixel unit in the second pixel row.

[0052] S520. Determine the target area where the second pixel row is located based on the luminance parameters of the pixel units in the second pixel row.

[0053] S530. Determine the compensation weight value of the pixel unit in the second pixel row according to the correspondence between the target area and the compensation weight value.

[0054] S540. Based on the initial compensation value and the compensation weight value, the luminance parameters of the M target pixel units in the second pixel row are compensated to obtain the compensated luminance parameters of the M target pixel units; M is a positive integer.

[0055] As described above, the compensation method for a display panel provided in this application embodiment refers to a second pixel row that contains line crosstalk. Specifically, when compensating for the line crosstalk in the second pixel row, the initial compensation value of the pixel unit in the second pixel row is obtained, and the target area of ​​the second pixel row is determined based on the luminance parameters of the pixel unit in the second pixel row. Then, based on the correspondence between the target area and the compensation weight value, the compensation weight value of the pixel unit in the second pixel row is determined. Finally, based on the initial compensation value and the compensation weight value, the luminance parameters of the target pixel unit in the second pixel row are compensated to obtain the compensated luminance parameters of the target pixel unit.

[0056] Compared to existing technologies, the compensation method for a display panel in this application takes into account the varying degrees of line crosstalk caused by the same DATA voltage difference at different locations on the display panel. If the same DATA voltage difference is compensated to the same degree uniformly according to existing technologies, the line crosstalk compensation effect will be poor. Therefore, this application determines the target area where the second pixel row is located, and then determines the compensation weight value of the pixel unit in the second pixel row based on the correspondence between the target area and the compensation weight value. In this way, by introducing a compensation weight value corresponding to the target area where the second pixel row is located, differential compensation can be performed on the second pixel row at different locations, thereby improving the line crosstalk compensation effect. This effectively and sufficiently improves the problem of uneven display brightness on the display panel, and thus effectively improves the display effect of the display panel.

[0057] The specific implementation methods of steps 510 to 540 described above will be described in detail below.

[0058] In S510, in a specific implementation, the initial compensation value of the pixel unit in the second pixel row can be determined based on the luminance parameters of the pixel unit in the first pixel row and the luminance parameters of the pixel unit in the second pixel row.

[0059] For example, the difference between the sum of the luminance parameters of multiple pixel units in the first pixel row and the sum of the luminance parameters of multiple pixel units in the second pixel row can be determined based on the luminance parameters of the pixel units in the first pixel row and the luminance parameters of the pixel units in the second pixel row. Then, based on the correspondence between different differences and the initial compensation value, the initial compensation value of the pixel units in the second pixel row under the current difference can be determined.

[0060] It should be noted that when determining the initial compensation value, the above-mentioned luminance parameters can be, for example, data voltage (Vdata), gamma register value, grayscale value to be displayed, and brightness value to be displayed.

[0061] The correspondence between the above difference and the initial compensation value can be set in advance based on actual compensation experience. For example, the larger the difference, the greater the compensation intensity for the second pixel row. Correspondingly, the initial compensation value of the pixel unit in the second pixel row can be set to be larger. This application does not impose strict limitations on this.

[0062] In S520, during the specific implementation, the target area where the second pixel row is located is determined based on the luminance parameters of the pixel units in the second pixel row.

[0063] In this embodiment, the target region where the second pixel row is located may be a non-crosstalk region (outside the crosstalk region) or a crosstalk region (inside the crosstalk region). It should be understood that the specific method for determining the target region will be explained in detail later, and will not be repeated here.

[0064] In S530, after determining the target area where the second pixel row is located, the compensation weight value of the pixel unit in the second pixel row can be determined according to the correspondence between the target area and the compensation weight value. The correspondence between the target area and the compensation weight value can be specifically set by taking into account the actual display panel performance, the data voltage of the pixel unit in the second pixel row, the PVDD jump situation, or other relevant factors, and this application does not impose strict limitations on it.

[0065] In S540, in specific implementation, after determining the compensation weight value of the pixel unit in the second pixel row according to the correspondence between the target area and the compensation weight value, the initial compensation value and the compensation weight value obtained in the previous steps are combined to compensate the luminance parameters of the M target pixel units in the second pixel row, so as to obtain the compensated luminance parameters of the M target pixel units.

[0066] The aforementioned M target pixel units can be all pixel units in the second pixel row, or a portion of the pixel units in the second pixel row, depending on the actual Line Crosstalk compensation requirements. This application does not impose specific restrictions in this regard.

[0067] In this embodiment, by introducing a compensation weight value corresponding to the target area where the second pixel row is located, differential compensation can be performed on the second pixel row in different areas, thereby improving the Line Crosstalk compensation effect. This effectively and fully improves the problem of uneven brightness of the display panel and effectively enhances the display effect of the display panel.

[0068] Please see below. Figure 6 , Figure 6 This is a schematic diagram of the structure of a target area in a display panel provided in an embodiment of this application. For example... Figure 6 As shown, according to some embodiments of this application, optionally, in order to more reasonably determine the target area where the second pixel row 20 is located, step 520, determining the target area where the second pixel row is located based on the luminance parameters of the pixel units in the second pixel row, may specifically include:

[0069] When the difference in luminance parameters between any two pixel units in the second pixel row is less than a first preset threshold, the target area where the second pixel row is located is determined to be a non-crosstalk area.

[0070] Combination Figure 6For example, taking the luminance parameter as the grayscale value, in the first pixel row 10, some pixel units have a grayscale value of 0, and some pixel units have a grayscale value of 255. In the second pixel row 20, the grayscale value of any two pixel units is 0. The second pixel row 20 is the pixel row where the Line Crosstalk (represented as a dark line) appears.

[0071] In the second pixel row 20, the grayscale value of any two pixel units is 0, meaning the difference in luminance parameters between any two pixel units in the second pixel row 20 is less than a first preset threshold. Thus, the target area where the second pixel row 20 is located can be determined as a non-crosstalk region, so that the compensation level for Line Crosstalk in this second pixel row 20 can be specifically determined according to the compensation weight value corresponding to the non-crosstalk region.

[0072] It should be noted that the first preset threshold mentioned above can be set based on relevant experience with Line Crosstalk, such as 3 gray levels, 10 gray levels, etc. This application does not make any specific limitation on this.

[0073] Please continue reading Figure 6 According to some embodiments of this application, optionally, for reasons similar to those in the foregoing embodiments, in order to more reasonably determine the target area where the second pixel row is located, the display panel may include a first display area and a second display area. The first display area may include at least the first pixel row 10; the second display area may include at least the second pixel row 20. Step 520, determining the target area where the second pixel row is located based on the luminance parameters of the pixel units in the second pixel row, may further include:

[0074] When displaying the target screen, if the first display area is used to display the mixed sub-screen and the second display area is used to display the first type of sub-screen or the second type of sub-screen, then the target area where the second pixel row 20 is located is determined to be a non-crosstalk area; the mixed sub-screen may include the first type of sub-screen and the second type of sub-screen arranged in the row direction.

[0075] In the first type of sub-image, the difference between the luminance parameter of each pixel unit and the first luminance parameter is less than a preset difference threshold, and in the second type of sub-image, the difference between the luminance parameter of each pixel unit and the second luminance parameter is less than a preset difference threshold.

[0076] In specific implementation, combined with Figure 6 For example, the first display area includes a first pixel row 10. If the first display area is used to display a mixed sub-screen, then the area where the first pixel row 10 is located can be determined as follows: Figure 6 Crosstalk region in the middle.

[0077] The second display area includes a second pixel row 20. If the second display area is used to display a first type of sub-screen or a second type of sub-screen, then the target area where the second pixel row 20 is located can be determined to be a non-crosstalk area. The second display area can be... Figure 6 The display area corresponding to the China-Africa crosstalk zone.

[0078] The first type of sub-screen mentioned above can be, for example, a white screen, and the second type of sub-screen can be, for example, a black screen. The mixed sub-screen can include the first type of sub-screen and the second type of sub-screen arranged in a row direction, for example... Figure 6 The crosstalk area presents white and black images arranged in the row direction.

[0079] The aforementioned first luminance parameter can be, for example, 10 gray levels. The difference between the luminance parameter of each pixel unit in the first type of sub-image and the first luminance parameter of 10 gray levels is less than a preset difference threshold, which can be set relatively small. In this way, the luminance parameter of any pixel in the first type of sub-image is close to the first luminance parameter.

[0080] Considering the scenarios where the Line Crosstalk phenomenon occurs, the difference between the first and second luminance parameters is relatively large. Therefore, the second luminance parameter can be, for example, 200 gray levels, and the luminance parameter of any pixel in the second type of sub-image is close to the second luminance parameter.

[0081] It should be understood that this application does not specifically limit the above-mentioned first luminous brightness parameter, second luminous brightness parameter, and preset difference threshold, etc. The specific parameters can be adaptively set in combination with relevant experience of Line Crosstalk.

[0082] Please see below. Figure 7 , Figure 7 This is a schematic diagram of the structure of a target area in a display panel provided in another embodiment of this application. For example... Figure 7 As shown, according to some embodiments of this application, optionally, determining the target area where the second pixel row is located based on the luminance parameters of the pixel units in the second pixel row may include:

[0083] When the difference in luminance parameters between two pixel units in the second pixel row is greater than a second preset threshold, the target area where the second pixel row is located is determined to be a crosstalk region.

[0084] Combination Figure 7 For example, in the first pixel row, the grayscale value of the pixel units is 0. In the second pixel row, some pixel units have a grayscale value of 0, and some pixel units have a grayscale value of 255. In this case, the second pixel row 20 is the pixel row where Line Crosstalk (represented as a bright line) occurs.

[0085] Considering the scenarios where line crosstalk occurs, the aforementioned second preset threshold is relatively large, such as 200 gray levels. When the difference in luminance parameters (e.g., gray levels 0 and 255) between two pixel units in the second pixel row exceeds the second preset threshold, the target area where the second pixel row 20 is located can be identified as a crosstalk region. Therefore, when compensating for the second pixel row 20 subsequently, the compensation degree for line crosstalk in this second pixel row 20 can be specifically determined by combining the compensation weight value corresponding to the crosstalk region.

[0086] Please continue reading Figure 7 According to some embodiments of this application, optionally, for reasons similar to those in the foregoing embodiments, in order to more reasonably determine the target area where the second pixel row is located, the display panel may include a first display area and a second display area; the first display area may include at least the first pixel row; the second display area may include at least the second pixel row; determining the target area where the second pixel row is located based on the luminance parameters of the pixel units in the second pixel row may include:

[0087] When displaying the target screen, if the first display area is used to display the first type of sub-screen or the second type of sub-screen, and the second display area is used to display the mixed sub-screen, then the target area where the second pixel row is located is determined to be the crosstalk area; the mixed sub-screen may include the first type of sub-screen and the second type of sub-screen arranged in the row direction;

[0088] In the first type of sub-image, the difference between the luminance parameter of each pixel unit and the first luminance parameter is less than a preset difference threshold, and in the second type of sub-image, the difference between the luminance parameter of each pixel unit and the second luminance parameter is less than a preset difference threshold.

[0089] In specific implementation, combined with Figure 7 For example, the first display area includes a first pixel row 10. If the first display area is used to display a first type of sub-screen or a second type of sub-screen, then the area where the first pixel row 10 is located can be determined as follows: Figure 7 The non-crosstalk region in the middle.

[0090] The second display area includes the second pixel row 20. If the second display area is used to display mixed sub-screens, then the target area where the second pixel row 20 is located can be determined to be a crosstalk area. The second display area can be... Figure 7 The display area corresponding to the crosstalk zone.

[0091] The first type of sub-screen mentioned above can be, for example, a white screen, and the second type of sub-screen can be, for example, a black screen. The mixed sub-screen can include the first type of sub-screen and the second type of sub-screen arranged in a row direction, for example... Figure 7 The crosstalk area presents white and black images arranged in the row direction.

[0092] The first luminous brightness parameter, the second luminous brightness parameter, and the preset difference threshold, etc., have been described above and will not be repeated here for the sake of brevity.

[0093] According to some embodiments of this application, optionally, in order to obtain the above-mentioned initial compensation value more reasonably, the above-mentioned acquisition of the initial compensation value of the pixel unit in the second pixel row may include:

[0094] The luminance parameters of the pixel units in the first pixel row are summed to obtain the sum of the first parameters;

[0095] The summation of the luminance parameters of the pixel units in the second pixel row is calculated to obtain the total second parameter.

[0096] The initial compensation value of the pixel unit in the second pixel row is determined based on the difference between the sum of the first parameter and the sum of the second parameter.

[0097] In specific implementation, taking the luminance parameter as the data voltage Vdata as an example, after obtaining the luminance parameters of the pixel units in the first pixel row and the second pixel row, the sum of the data voltages Vdata of the pixel units corresponding to the first pixel row (upper line) is calculated to obtain the sum of the first parameters mentioned above. The sum of the data voltages Vdata of the pixel units corresponding to the second pixel row (lower line) is calculated to obtain the sum of the second parameters mentioned above.

[0098] Thus, after calculating the sum of the first parameter and the sum of the second parameter respectively, the initial compensation value of the pixel unit in the second pixel row is determined based on the difference between the sum of the first parameter and the sum of the second parameter.

[0099] It should be noted that a correspondence table between the above difference (the difference between the upper and lower Line-V data) and the initial compensation value can be established in advance to quickly determine the initial compensation value corresponding to the difference calculated above.

[0100] For example, see Figure 8 , Figure 8 This is a schematic diagram illustrating the relationship between the initial compensation value and the difference between the upper and lower Line-Vdata values ​​provided in the embodiments of this application. In practical applications, after obtaining... Figure 8 After obtaining the relationship curve shown, the initial compensation value can be quickly retrieved after calculating the difference between the sum of the first parameter and the sum of the second parameter (the difference between the upper and lower Line-Vdata), which helps to improve the Line Crosstalk compensation efficiency of the display panel.

[0101] The inventors of this application discovered through research that the observability of the Line Crosstalk phenomenon by the human eye varies in different scenarios. Due to the limitations of the human eye's ability to capture information, the Line Crosstalk phenomenon is not easily observed in some scenarios, even when it occurs. However, in other scenarios, such as at the boundary between black and white areas, the Line Crosstalk phenomenon is easily observed by the human eye.

[0102] Based on this, in order to more effectively compensate for the Line Crosstalk phenomenon in the second pixel row and improve compensation efficiency, according to some embodiments of this application, optionally, before compensating the luminance parameters of the M target pixel units in the second pixel row based on the initial compensation value and the compensation weight value, the compensation method of the display panel may further include:

[0103] Based on the luminance parameters of multiple pixel units in the first pixel row and the luminance parameters of multiple pixel units in the second pixel row, M target pixel units are determined.

[0104] Please see the figure below. Figure 9 This is a schematic diagram of another display panel structure provided in an embodiment of this application. For example... Figure 9 As shown, in some more specific embodiments, in order to more reasonably determine the M target pixel units that need to be compensated in the second pixel row, the determination of the M target pixel units based on the luminance parameters of multiple pixel units in the first pixel row and the luminance parameters of multiple pixel units in the second pixel row may include:

[0105] Determine the target difference between the luminance parameters of the first pixel unit and the luminance parameters of the second pixel unit;

[0106] If the target difference is greater than the third preset threshold, the second pixel unit will be determined as a pixel unit among the M target pixel units;

[0107] The first pixel row may include a first pixel unit, which is any pixel unit of the plurality of pixel units in the first pixel row; the second pixel row may include a second pixel unit; the second pixel unit and the first pixel unit are arranged correspondingly in the column direction.

[0108] Combination Figure 9 For example, the first pixel unit is located in the first pixel row 10, and the second pixel unit is located in the second pixel row 20. The first pixel unit and the second pixel unit are arranged correspondingly in the column direction, that is, the first pixel unit and the second pixel unit are located in the same column.

[0109] In practice, the target difference between the luminance parameters of the first pixel unit and the second pixel unit in different columns is first determined. If the target difference for a certain column is greater than a third preset threshold, it indicates that the line crosstalk phenomenon of the second pixel unit in that column is easily observed.

[0110] In this case, the second pixel unit in this column is determined as a pixel unit in the second pixel row 20 that needs to be compensated by LineCrosstalk, that is, the second pixel unit is determined as a pixel unit among the M target pixel units.

[0111] In this embodiment, based on the luminance parameters of multiple pixel units in the first pixel row and the luminance parameters of multiple pixel units in the second pixel row, the target pixel units in the second pixel row that need to be compensated for Line Crosstalk can be effectively determined. This is beneficial for more targeted compensation of the Line Crosstalk phenomenon in the second pixel row, thereby helping to improve the compensation efficiency of the display panel.

[0112] According to some embodiments of this application, optionally, in order to make the determined compensation weight values ​​more reasonable and comprehensive, the above-mentioned determination of the compensation weight values ​​of pixel units in the second pixel row based on the correspondence between the target area and the compensation weight values ​​may include:

[0113] Based on the correspondence between the target area and the compensation weight value, and the luminance parameters of the M target pixel units, the compensation weight value of the pixel units in the second pixel row is determined.

[0114] In practice, in addition to being related to the target area where the second pixel row is located, the magnitude of the above-mentioned compensation weight value can also be related to the specific luminous brightness parameters (e.g., data voltage Vdata) of the above-mentioned M target pixel units (bright line and dark line areas).

[0115] It should be understood that, considering that the actual compensation weight value setting may also be affected by factors such as panel performance and other factors, this embodiment does not specifically limit how to determine the compensation weight value of the pixel unit in the second pixel row.

[0116] Please see below. Figure 10 , Figure 10 This is a schematic diagram illustrating the compensation relationship between line crosstalk, initial compensation value, and compensation weight value, provided in an embodiment of this application.

[0117] like Figure 10As shown, according to some embodiments of this application, optionally, in order to more effectively compensate for the Line Crosstalk phenomenon in the second pixel row, the above-mentioned compensation of the luminance parameters of the M target pixel units in the second pixel row based on the initial compensation value and the compensation weight value, to obtain the compensated luminance parameters of the M target pixel units, may include:

[0118] The luminance parameters of the M target pixel units in the second pixel row are compensated based on the product of the initial compensation value and the compensation weight value, so as to obtain the compensated luminance parameters of the M target pixel units.

[0119] After compensating for the luminance parameters of the M target pixel units in the second pixel row, the compensation method for the display panel may further include:

[0120] Based on the luminance parameters of the M target pixel units after compensation, the M target pixel units are driven for display.

[0121] The following is combined with Figure 10 To illustrate, in related technologies, the strength of Line Crosstalk compensation is often determined by the difference in data voltage between two lines (the first pixel line and the second pixel line). However, whether the Line Crosstalk influence area is in or outside the crosstalk region will result in different degrees of Line Crosstalk caused by the same difference in data voltage between two lines.

[0122] For example Figure 10 , Figure 10 Positions 01 and 03 are within the crosstalk region, while positions 02 and 04 are within the crosstalk bar. Taking positions 01 and 04 as examples, the difference in data voltage between the upper and lower lines of positions 01 and 04 is the same. However, due to the inconsistency of data voltage Vdata at positions 01 and 04 and the influence of other factors, the degree of line crosstalk influence at positions 01 and 04 is different.

[0123] Therefore, if the same initial compensation value A is used for both the Line Crosstalk at position 01 and position 04, then at least one of the positions 01 and 04 will have poor Line Crosstalk compensation.

[0124] In this embodiment, depending on whether the area affected by Line Crosstalk is within the crosstalk zone (crosstalk zone) or outside the crosstalk zone (non-crosstalk zone), corresponding position weights (compensation weight values) are set for positions 01 and 04 respectively, namely, Gain inside and Gain outside. Finally, the Line Crosstalk compensation intensity of positions 01 and 04 is obtained by multiplying the difference between the upper and lower Line-V data by the position weight.

[0125] Specifically, such as Figure 10 As shown, the Line Crosstalk at position 01 is compensated based on the product of the initial compensation value A and the compensation weight value Gain, to obtain the compensated luminance parameter at position 01. The Line Crosstalk at position 04 is compensated based on the product of the initial compensation value A and the compensation weight value Gain, to obtain the compensated luminance parameter at position 04.

[0126] Thus, the final compensation intensity of Line Crosstalk in this embodiment is determined by the difference between the upper and lower Line-Vdata and the area affected by Line Crosstalk. It can perform differential compensation for Line Crosstalk in different areas, thereby improving the Line Crosstalk compensation effect. This can effectively and fully improve the problem of uneven display brightness of the display panel, and thus effectively improve the display effect of the display panel.
