Description

Technical Field

[0001] This application belongs to the field of display panel technology, and particularly relates to a method, apparatus, device and storage medium for crosstalk compensation of display panels. Background Technology

[0002] With the continuous development of display panel technology, OLED (Organic Light-Emitting Diode) devices and other light-emitting devices have been gradually applied to various display panel products such as mobile phones, tablets, and laptops.

[0003] The scan signal lines in the display panel can output scan signals line by line to provide scan signals to each row of light-emitting sub-pixels in sequence. However, when there is a significant brightness difference between a certain area of ​​the image to be displayed and other areas, the data signal lines will start from the first pixel row of that area and provide a different data signal voltage to the light-emitting sub-pixels with brightness differences than to other pixel rows. This will cause a sudden change in the data voltage on the data signal lines.

[0004] Because there are coupling capacitors between the data signal line and the power signal line, when the voltage of the data signal line changes abruptly, the power supply voltage on the power signal line will be affected by the synchronous coupling and fluctuate, resulting in signal crosstalk and affecting the display effect. Summary of the Invention

[0005] This application provides a method, apparatus, device, and storage medium for crosstalk compensation of a display panel, which can improve the technical problem that the coupling effect between data signal lines and power signal lines can easily lead to fluctuations in power supply voltage and generate signal crosstalk.

The first typical value is calculated based on the luminance parameters corresponding to the luminous sub-pixels of the first pixel row, and the second typical value is calculated based on the luminance parameters corresponding to the luminous sub-pixels of the second pixel row. Any luminous sub-pixel corresponding to the first typical value is not located in the same luminous sub-pixel column as any luminous sub-pixel corresponding to the second typical value.

[0008] The first compensation parameter is determined based on the brightness parameter compensation relationship, the first typical value, and the second typical value for the first pixel row in each pair of adjacent pixel rows.

[0009] The final compensation value of the third pixel row is determined based on the first compensation parameter corresponding to the third pixel row; the third pixel row is any row among multiple pixel rows; the final compensation value is used to compensate the data signal voltage of each luminous sub-pixel in the third pixel row.

[0010] In some embodiments, the number of partial light-emitting sub-pixels corresponding to the first typical value is the same as the number of partial light-emitting sub-pixels corresponding to the second typical value.

[0011] In some embodiments, the luminance parameter is the Gamma register value corresponding to the luminous sub-pixel. The first typical value is the sum of the Gamma register values ​​of multiple luminous sub-pixels in the first pixel row, and the second typical value is the sum of the Gamma register values ​​of multiple luminous sub-pixels in the second pixel row.

The third pixel row is any row among multiple pixel rows. The final compensation value is used to compensate the data signal voltage of each luminous sub-pixel in the third pixel row.

[0022] In some embodiments, the final compensation value of the third pixel row is determined based on the data compensation value corresponding to the third pixel row in the first compensation parameters corresponding to the third pixel row, and the data compensation values ​​corresponding to the third pixel row in the first compensation parameters corresponding to the third pixel row for the consecutive (K-1) pixel rows preceding the third pixel row, including:

[0024] The final compensation value of the third pixel row is determined based on the K data compensation values ​​corresponding to the third pixel row from the K first compensation parameters corresponding to the third pixel row and the preceding (K-1) rows.

[0025] In some embodiments, the formula for calculating the final compensation value is as follows:

[0026]

[0027] Where V is the final compensation value, a i Here, A(N+1-i) represents the weighting coefficient, N is the row number of the first pixel row, and A(N+1-i) represents the weighting coefficient. i This is the data compensation value corresponding to the Nth row in the first compensation parameter corresponding to the (N+1-i)th row.

[0031] In some embodiments, the display panel includes a plurality of multiplexing modules. The input terminals of the multiplexing modules are connected to the data signal fan-out lines. The multiplexing modules include four output terminals. In two adjacent columns of light-emitting sub-pixels, one column of light-emitting sub-pixels is alternately connected to two of the output terminals, and the other column of light-emitting sub-pixels is alternately connected to the other two output terminals.

[0032] Thirdly, embodiments of this application provide a crosstalk compensation device for a display panel, the device comprising:

[0033] The first extraction module is used to determine a first typical value and a second typical value based on the luminance parameters corresponding to the luminous sub-pixels of some of the adjacent two pixel rows, respectively; wherein, each pair of adjacent pixel rows includes a first pixel row and a second pixel row, in a single luminous frame, the first pixel row first receives a scanning signal, the first typical value is calculated based on the luminance parameters corresponding to the luminous sub-pixels of some of the first pixel row, and the second typical value is calculated based on the luminance parameters corresponding to the luminous sub-pixels of some of the second pixel row; any one of the luminous sub-pixels corresponding to the first typical value and any one of the luminous sub-pixels corresponding to the second typical value are not located in the same column of luminous sub-pixels;

[0034] The first query module is used to determine the first compensation parameter corresponding to the first pixel row in every two adjacent pixel rows based on the brightness parameter compensation relationship, the first typical value and the second typical value.

[0035] The first calculation module is used to determine the final compensation value of the third pixel row according to the first compensation parameter corresponding to the third pixel row; the third pixel row is any row among multiple pixel rows; the final compensation value is used to compensate the data signal voltage of each luminous sub-pixel in the third pixel row;

[0036] Alternatively, the device includes:

[0037] The second extraction module is used to determine a first typical value and a second typical value based on the luminance parameters corresponding to the luminance sub-pixels of each of two adjacent pixel rows. Each of two adjacent pixel rows includes a first pixel row and a second pixel row. In a single luminous frame, the first pixel row receives a scanning signal first. The first typical value is calculated based on the luminance parameters corresponding to the luminance sub-pixels of the first pixel row, and the second typical value is calculated based on the luminance parameters corresponding to the luminance sub-pixels of the second pixel row.

[0038] The second query module is used to determine the first compensation parameter corresponding to the first pixel row in each pair of adjacent pixel rows based on the brightness parameter compensation relationship, the first typical value and the second typical value; the first compensation parameter includes at least the data compensation values ​​corresponding to the first pixel row and at least (K-1) consecutive pixel rows thereafter; where K is greater than or equal to 2 and K is a positive integer.

[0039] The second calculation module is used to determine the final compensation value of the third pixel row based on the data compensation value of the third pixel row in the first compensation parameter corresponding to the third pixel row, and the data compensation values ​​of the third pixel row in the first compensation parameter corresponding to the third pixel row of the consecutive (K-1) pixel rows before the third pixel row; the third pixel row is any row among multiple pixel rows; the final compensation value is used to compensate the data signal voltage of each luminous sub-pixel in the third pixel row.

[0040] Fourthly, embodiments of this application provide a crosstalk compensation device for a display panel, the crosstalk compensation device for the display panel including: a processor and a memory storing computer program instructions;

[0041] When the processor executes computer program instructions, it implements the crosstalk compensation method for the display panel in the above embodiments.

[0042] Fifthly, embodiments of this application provide a computer storage medium storing computer program instructions, which, when executed by a processor, implement the crosstalk compensation method for the display panel described above.

[0043] Compared with the prior art, the crosstalk compensation method, apparatus, device, and storage medium for display panels provided in this application determine a first typical value by using the luminance parameters of some luminous sub-pixels in the first pixel row of every two adjacent pixel rows, and a second typical value by using the luminance parameters of some luminous sub-pixels in the second pixel row of every two adjacent pixel rows. This allows for the determination of a first compensation parameter corresponding to the first pixel row from the luminance parameter compensation relationship based on the luminance difference between the two pixel rows represented by the two typical values. When selecting the luminous sub-pixels needed to calculate the first and second typical values ​​from the first and second pixel rows respectively, it is possible to set any one of the luminous sub-pixels corresponding to the first typical value to be outside the same luminous sub-pixel column as any one of the luminous sub-pixels corresponding to the second typical value, thereby improving the accuracy of the luminance difference represented by the first and second typical values. If the luminance difference between the first and second pixel rows is large, the absolute value of the data compensation value corresponding to the first compensation parameter is large; if the luminance difference between the two pixel rows is small, the final compensation value corresponding to the first compensation parameter is small. After determining the final compensation value for each pixel row, the data signal voltage of the light-emitting sub-pixels in each pixel row can be adjusted to compensate for the final compensation value, so as to improve the signal crosstalk caused by the coupling effect of the power signal line and ensure the display effect of the display panel.

[0057] 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 of this application.

[0058] 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.

[0059] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The embodiments will now be described in detail with reference to the accompanying drawings.

[0060] With the continuous development of display panel technology, OLED (Organic Light-Emitting Diode) devices and other light-emitting devices have been gradually applied to various display panel products such as mobile phones, tablets, and laptops.

[0061] The scan signal lines in the display panel can output scan signals line by line to provide scan signals to each row of light-emitting sub-pixels in sequence. However, when there is a significant brightness difference between a certain area of ​​the image to be displayed and other areas, the data signal lines will start from the first pixel row of that area and provide a different data signal voltage to the light-emitting sub-pixels with brightness differences than to other pixel rows. This will cause a sudden change in the data voltage on the data signal lines.

[0062] Because there are coupling capacitors between the data signal line and the power signal line, when the voltage of the data signal line changes abruptly, the power supply voltage on the power signal line will be affected by the synchronous coupling and fluctuate, resulting in signal crosstalk and affecting the display effect.

[0063] To address the aforementioned technical problems, embodiments of this application provide a method, apparatus, device, and storage medium for crosstalk compensation of a display panel. The crosstalk compensation method for a display panel provided in this application embodiment will be described first below.

[0064] Figure 1 A flowchart illustrating a crosstalk compensation method for a display panel according to an embodiment of this application is shown. The display panel includes multiple pixel rows, and the crosstalk compensation method for the display panel includes:

[0065] S110, determine a first typical value and a second typical value based on the luminance parameters corresponding to the luminous sub-pixels of each pair of adjacent pixel rows; wherein each pair of adjacent pixel rows includes a first pixel row and a second pixel row, and in a single luminous frame, the first pixel row may be the first to receive the scan signal, the first typical value is calculated based on the luminance parameters corresponding to the luminous sub-pixels of the first pixel row, and the second typical value is calculated based on the luminance parameters corresponding to the luminous sub-pixels of the second pixel row; any one of the luminous sub-pixels corresponding to the first typical value and any one of the luminous sub-pixels corresponding to the second typical value are not located in the same luminous sub-pixel column;

[0066] S120, determine the first compensation parameter corresponding to the first pixel row in each pair of adjacent pixel rows according to the brightness parameter compensation relationship, the first typical value and the second typical value;

[0067] S130, determine the final compensation value of the third pixel row according to the first compensation parameter corresponding to the third pixel row; the third pixel row is any row among multiple pixel rows; the final compensation value is used to compensate the data signal voltage of each luminous sub-pixel in the third pixel row.

[0068] The crosstalk compensation method for a display panel provided in this embodiment can be applied to a crosstalk compensation device for a display panel. This device can, when there is a large brightness difference in the displayed content of two adjacent pixel rows, perform targeted compensation on the data signal voltage of the light-emitting sub-pixels starting from the previous pixel row, based on the brightness parameter compensation relationship, to improve the signal crosstalk problem between the data signal lines and the power signal lines. The display panel can be a PC, television, smart terminal, or tablet computer, etc. This embodiment does not limit the specific form of the display panel.

[0069] In this embodiment, a first typical value is determined by the luminance parameters of some luminous sub-pixels in the first pixel row of every two adjacent pixel rows, and a second typical value is determined by the luminance parameters of some luminous sub-pixels in the second pixel row of every two adjacent pixel rows. This allows for the determination of a first compensation parameter corresponding to the first pixel row from the luminance parameter compensation relationship based on the luminance difference between the two pixel rows represented by the two typical values. When selecting the luminous sub-pixels needed to calculate the first and second typical values ​​from the first and second pixel rows respectively, it is possible to set any one of the luminous sub-pixels corresponding to the first typical value to be outside the same luminous sub-pixel column as any one of the luminous sub-pixels corresponding to the second typical value, thereby improving the accuracy of the luminance difference represented by the first and second typical values. If the luminance difference between the first and second pixel rows is large, the absolute value of the data compensation value corresponding to the first compensation parameter is large; if the luminance difference between the two pixel rows is small, the final compensation value corresponding to the first compensation parameter is small. After determining the final compensation value for each pixel row, the data signal voltage of each row of light-emitting sub-pixels can be adjusted based on the final compensation value to improve the signal crosstalk caused by the coupling effect of the power signal line and ensure the display effect of the display panel.

[0070] In S110, the display panel includes multiple pixel rows. When displaying an image on the display panel, the luminous brightness parameters corresponding to each luminous sub-pixel can be determined according to the image data of the image. When the scanning signal line outputs the scanning signal line line by line, the corresponding data signal is provided line by line through the data signal line according to the luminous brightness parameters of the luminous sub-pixels in each row.

[0071] When the luminance parameters of a row of luminous sub-pixels differ significantly from those of the previous row, the data voltage supplied to the luminous sub-pixels by the data signal line experiences a larger voltage change compared to the previous row. Because parasitic capacitance exists between the data signal lines and power signal lines within the display panel, a significant change in the data voltage on the data signal line will cause the power signal on the power signal line to fluctuate in the same direction due to the coupling effect of this parasitic capacitance. Figure 2 This illustrates the coupling effect of parasitic capacitance between the data signal line and the power signal line on the power supply voltage when the data voltage increases and decreases. For example... Figure 2 As shown, when the data voltage increases, the power signal line is affected by the synchronous coupling of parasitic capacitance, causing the power supply voltage to fluctuate in the same direction; that is, the power supply voltage increases briefly and then returns to its normal value. Conversely, when the data voltage decreases, the power signal line is affected by the synchronous coupling of parasitic capacitance, causing the power supply voltage to decrease briefly and then return to its normal value.

[0072] Taking an increase in data voltage as an example, during periods of power supply voltage variation, the driving current of the emitting sub-pixel will be affected by the voltage change, leading to higher luminance of the emitting sub-pixel. In this case, crosstalk compensation can be applied to the data signal voltage using a corresponding compensation voltage, ensuring that the actual voltage received by the emitting sub-pixel is the sum of the data voltage and the compensation voltage. When the emitting sub-pixel receives the compensated data voltage, it can compensate for the brightness changes caused by power supply voltage fluctuations, thereby reducing the brightness variations caused by power supply voltage fluctuations and improving signal crosstalk.

[0073] Figure 3 The image shown is affected by signal crosstalk. A single image frame displayed on the display panel includes a first image region 11, a second image region 12, and a third image region 13. The luminous intensity of a portion of the second image region 12 is significantly lower than that of the first image region 11 and the third image region 13. When the display panel provides data signals to the luminous sub-pixels row by row, due to the significant brightness difference between the last row of pixels in the first image region 11 and the first row of pixels in the second image region 12, the data signals provided by the data signal lines to adjacent rows of pixels also exhibit significant variations. At this time, the voltage change of the data signal will cause the parasitic capacitance between the data signal lines and the power signal lines to synchronously couple with the power supply voltage, resulting in voltage fluctuations in the power supply voltage. Similarly, at the boundary between the second image region 12 and the third image region 13, the data signal provided by the data signal lines will also experience significant voltage changes, resulting in voltage fluctuations in the power supply voltage.

[0074] The data voltage received by a light-emitting sub-pixel can be negatively correlated with its brightness. As the data voltage increases, the brightness of the sub-pixel gradually decreases, reaching zero when the data voltage reaches the black state. Therefore, as the data voltage on the data signal line increases, the brightness of the sub-pixels in that row gradually decreases compared to the previous row. However, due to the capacitive coupling between the data signal line and the power signal line, the power supply voltage increases due to synchronous coupling as the data voltage increases. The driving current of the light-emitting element in the sub-pixel is positively correlated with the power supply voltage; as the power supply voltage increases, the driving current increases accordingly, leading to an increase in the brightness of the sub-pixel. While the brightness of the sub-pixel should decrease as the data voltage increases, the power supply voltage fluctuations caused by signal crosstalk on the power signal line can actually increase the brightness of the sub-pixel, resulting in poor display quality.

[0075] like Figure 3 As shown, at the boundary between the first image region 11 and the second image region 12, the emitting sub-pixels, driven by an increased power supply voltage, will produce a relatively bright line. Correspondingly, at the boundary between the second image region 12 and the third image region 13, the emitting sub-pixels, driven by a decreased power supply voltage, will produce a relatively dark bright line. The horizontal lines generated at the boundary between the first image region 11 and the second image region 12, and at the boundary between the second image region 12 and the third image region 13, represent signal crosstalk.

[0076] To mitigate the impact of signal crosstalk between data signal lines and power signal lines on image quality, the device compensates for the data signal voltage when providing it to each row of luminous sub-pixels. This compensates for brightness variations caused by power supply voltage fluctuations when the luminous sub-pixels receive the compensated data signal voltage, thereby reducing brightness variations resulting from signal crosstalk affecting the power supply voltage.

[0077] When displaying an image, taking the provision of data signal voltage to two adjacent pixel rows by the display panel as an example, the two adjacent pixel rows can include a first pixel row and a second pixel row. Based on the image data of the image, the luminance parameters corresponding to a portion of the luminous sub-pixels in the first pixel row and the luminance parameters corresponding to a portion of the luminous sub-pixels in the second pixel row can be determined. Within a single image frame, the luminous sub-pixels in the first pixel row receive the valid signal of the scan signal first, and the luminous sub-pixels in the second pixel row receive the valid signal of the scan signal subsequently.

[0078] The device can calculate a first typical value based on the luminance parameters of some luminous sub-pixels in the first pixel row, and calculate a second typical value based on the luminance parameters of some luminous sub-pixels in the second pixel row. Furthermore, any luminous sub-pixel in the first pixel row corresponding to the first typical value and any luminous sub-pixel in the second pixel row corresponding to the second typical value are not located in the same luminous sub-pixel column. That is, among two luminous sub-pixels located in the same luminous sub-pixel column in the first and second pixel rows, if one participates in the calculation of the first or second typical value, the other does not participate in the calculation of either the second or first typical value. It is understood that the first typical value characterizes the overall luminance parameter of the first pixel row, and the second typical value characterizes the overall luminance parameter of the second pixel row.

[0079] It should be noted that when the display panel includes multiple pixel rows, for each pair of adjacent pixel rows, the first typical value and the second typical value can be determined respectively based on the luminous brightness parameters corresponding to the partial luminous sub-pixels of the two pixel rows.

[0080] As an optional embodiment, the number of partial light-emitting sub-pixels corresponding to the first typical value and the number of partial light-emitting sub-pixels corresponding to the second typical value can be set to be the same.

[0081] The first typical value is calculated by selecting a subset of luminous sub-pixels from the first pixel row and calculating the corresponding luminance parameters. Similarly, the second typical value is calculated by selecting a subset of luminous sub-pixels from the second pixel row and calculating the corresponding luminance parameters. To avoid excessive errors between the first and second typical values, the number of luminous sub-pixels corresponding to the first typical value can be the same as that of the second typical value. For example, when calculating the first typical value using the luminance parameters of 20 luminous sub-pixels from the first pixel row, the second typical value can also be calculated using the luminance parameters of 20 luminous sub-pixels from the second pixel row.

[0082] In one optional implementation, the portion of the light-emitting sub-pixels selected from the first pixel row may also be a series of consecutive light-emitting sub-pixels, and the portion of the light-emitting sub-pixels selected from the second pixel row may also be a series of consecutive light-emitting sub-pixels, and the light-emitting sub-pixels selected from the first pixel row and the light-emitting sub-pixels selected from the second pixel row are not located on the same pixel column.

[0083] As an optional embodiment, the luminance parameter is the Gamma register value corresponding to the luminous sub-pixel. The first typical value is the sum of the Gamma register values ​​of multiple luminous sub-pixels in the first pixel row, and the second typical value is the sum of the Gamma register values ​​of multiple luminous sub-pixels in the second pixel row.

[0084] Please refer to Figure 4 As an optional embodiment, the above-described S110 may include:

[0085] S210, determine the first typical value based on the luminance parameter corresponding to the luminous sub-pixel of the even column of the first pixel row of every two adjacent pixel rows;

[0086] S220, determine the second typical value based on the luminance parameter corresponding to the luminous sub-pixel of the odd column of the second pixel row of every two adjacent pixel rows.

[0087] In this embodiment, some of the luminous sub-pixels selected from the first pixel row can be luminous sub-pixels at even-numbered positions, i.e., luminous sub-pixels in even-numbered columns. A first typical value can be calculated based on the luminance parameters corresponding to the luminous sub-pixels in the even-numbered columns. Correspondingly, some of the luminous sub-pixels selected from the second pixel row can be luminous sub-pixels in odd-numbered columns.

[0088] In S210, in every two adjacent pixel rows, some of the luminous sub-pixels in the first pixel row can be luminous sub-pixels at even-numbered positions in the first pixel row. The device can determine the luminance parameters corresponding to the luminous sub-pixels at each even-numbered position in the first pixel row from the image data, and calculate a first typical value based on the luminance parameters at the even-numbered positions.

[0089] In S220, in each pair of adjacent pixel rows, the device can also determine the luminance parameter corresponding to each odd-numbered position of the luminous sub-pixel in the second pixel row based on the image data, and calculate the second typical value based on the luminance parameter of the odd-numbered position.

[0090] When the display panel includes multiple pixel rows, for each two adjacent pixel rows, a first pixel row and a second pixel row can be divided. Using the above-mentioned odd-even column method, a first typical value is determined based on the light-emitting sub-pixels in the even-numbered columns of the first pixel row, and a second typical value is determined based on the light-emitting sub-pixels in the odd-numbered columns of the second pixel row.

[0091] When the display panel's wiring architecture is a dual data line architecture, the same data signal fan-out line can be electrically connected to two columns of luminous sub-pixels, providing data signals to both columns through time-division multiplexing. In the two columns of luminous sub-pixels connected to the same data signal fan-out line, the odd-numbered columns of the same row receive the data signal first, followed by the even-numbered columns. Therefore, when there is a significant difference in luminous intensity between two adjacent pixel rows, the data signal received by the even-numbered columns in the preceding row and the data signal received by the odd-numbered columns in the following row will have a large voltage difference. This can easily lead to signal crosstalk caused by parasitic capacitance coupling affecting the power supply voltage of the power signal line. By obtaining the luminous brightness parameters of the even-numbered columns of luminous sub-pixels in the preceding pixel row and the odd-numbered columns in the following pixel row, the difference between the first and second typical values ​​can be used to determine whether there is a significant brightness difference in the image content displayed in the two pixel rows. This allows for the determination of the final compensation value for the first pixel row and the compensation of the data signal voltage for each luminous sub-pixel in the first pixel row.

[0092] In another implementation, if the same data signal fan-out line is connected to two columns of light-emitting sub-pixels, and the data signal is provided first to the even-numbered columns of light-emitting sub-pixels and then to the odd-numbered columns of light-emitting sub-pixels, then the selected portion of the light-emitting sub-pixels in the first pixel row can be the light-emitting sub-pixels in the odd-numbered columns, and the selected portion of the light-emitting sub-pixels in the second pixel row can be the light-emitting sub-pixels in the even-numbered columns.

[0093] In this embodiment, the luminance parameter of the luminous sub-pixel is the Gamma register value corresponding to the luminous sub-pixel. A first typical value can be the sum of the Gamma register values ​​corresponding to some luminous sub-pixels in the first pixel row. A second typical value can be the sum of the Gamma register values ​​corresponding to some luminous sub-pixels in the second pixel row.

[0094] For example, after the device selects the Gamma register value corresponding to the luminous sub-pixel at an odd position from the first pixel row, the sum of multiple Gamma register values ​​can be calculated as a first typical value. After the device selects the Gamma register value corresponding to the luminous sub-pixel at an even position from the second pixel row, the sum of multiple Gamma register values ​​can be calculated as a second typical value.

[0095] Using the sum of multiple Gamma register values ​​corresponding to the odd-numbered luminous sub-pixels of the first pixel row as the first typical value, the overall luminous brightness of the first pixel row can be characterized. Similarly, using the sum of multiple Gamma register values ​​corresponding to the even-numbered luminous sub-pixels of the second pixel row as the second typical value, the overall luminous brightness of the second pixel row can also be characterized.

[0096] When using the sum of the Gamma register values ​​of multiple selected luminous sub-pixels as the first typical value and the second typical value, it is necessary to ensure that the number of luminous sub-pixels selected in the first pixel row is consistent with the number of luminous sub-pixels selected in the second pixel row.

[0097] In another embodiment, the first typical value and the second typical value may also be the average or weighted average of multiple Gamma register values, etc., and there is no limitation here. When the first typical value and the second typical value are the average or weighted average of Gamma register values, the number of luminous sub-pixels selected from the first pixel row and the number of luminous sub-pixels selected from the second pixel row may be the same or different.

[0098] In S120, after determining the first typical value corresponding to the first pixel row and the second typical value corresponding to the second pixel row in every two adjacent pixel rows, the first compensation parameter corresponding to the first typical value and the second typical value can be determined according to the pre-stored brightness parameter compensation relationship. This first compensation parameter is the first compensation parameter corresponding to the first pixel row.

[0099] In two adjacent pixel rows, the first pixel row to be lit is the first pixel row. Based on the first typical value and the second typical value corresponding to the two pixel rows, respectively, the first compensation parameter corresponding to the first pixel row can be obtained. For multiple pixel rows of the display panel, the first compensation parameter corresponding to the first pixel row to be lit can be determined for every two adjacent pixel rows. That is, based on the image data of a single illuminated frame, the first compensation parameter corresponding to each pixel row as the first pixel row in two adjacent pixel rows can be determined.

[0100] Please refer to Figure 5 As an optional embodiment, the above-described S120 may include:

[0101] S310, compare the first typical value and the second typical value corresponding to each pair of adjacent pixel rows to obtain the comparison result;

[0102] S320, determine the first compensation parameter corresponding to the first pixel row in every two adjacent pixel rows according to the brightness parameter compensation relationship and the comparison result; the brightness parameter compensation relationship is the correspondence between the comparison result and the first compensation parameter.

[0103] In this embodiment, for each pair of adjacent pixel rows, a first typical value and a second typical value can be compared to calculate a comparison result. The brightness parameter compensation relationship can include the correspondence between the comparison result and the first compensation parameter. Based on the comparison result, the corresponding first compensation parameter can be determined from the brightness parameter compensation relationship. This first compensation parameter is the first compensation parameter corresponding to the first pixel row that is lit first among the two adjacent pixel rows. By performing the above process on multiple pixel rows respectively, the first compensation parameter corresponding to each pixel row can be obtained.

[0104] In S310, after determining the first typical value and the second typical value corresponding to two adjacent pixel rows respectively, the comparison result obtained by comparing the first typical value and the second typical value can be determined.

[0105] Since the first typical value and the second typical value can respectively characterize the overall luminance of the first pixel row and the overall luminance of the second pixel row, the difference between the first typical value and the second typical value can characterize the overall luminance difference between two adjacent pixel rows. Therefore, the comparison result obtained by comparing the first typical value and the second typical value can be the difference between the first typical value and the second typical value.

[0106] In another embodiment, the overall brightness difference between two adjacent pixel rows can also be reflected by the ratio of the first typical value to the second typical value. The comparison result obtained by comparing the first typical value and the second typical value can also be the quotient of the first typical value and the second typical value.

[0107] In S320, after determining the comparison result between the first typical value and the second typical value, a pre-stored brightness parameter compensation relationship can be obtained. This brightness parameter compensation relationship is the correspondence between the overall brightness difference between two adjacent pixel rows and the first compensation parameter. Since the overall brightness difference between two adjacent pixel rows can be represented by the comparison result obtained by comparing the first typical value and the second typical value, the brightness parameter compensation relationship can also be the correspondence between the comparison result and the first compensation parameter.

[0108] Taking the comparison result obtained by comparing the first typical value and the second typical value in the above embodiment as the difference between the first typical value and the second typical value as an example, after determining the difference between the first typical value and the second typical value, the corresponding first compensation parameter can be determined according to the brightness parameter compensation relationship.

[0109] The aforementioned brightness parameter compensation relationship can be a lookup table (LUT). After determining the overall brightness difference between two adjacent pixel rows based on the first and second typical values ​​(i.e., the comparison result), the corresponding first compensation parameter can be obtained from the lookup table based on this comparison result. The first compensation parameter stored in the lookup table can be the change in data signal voltage obtained by adjusting the signal voltage of the data signal to improve the brightness difference during pre-brightness difference adjustment of the display panel.

[0110] In S130, based on each pair of adjacent pixel rows, the first pixel row to be lit can be determined as the first pixel row, and the first compensation parameter corresponding to the first pixel row can be determined. After performing the above operation on multiple pixel rows of the display panel, the first compensation parameter corresponding to each pixel row in a single image frame can be obtained.

[0111] Taking the third pixel row as an example, the third pixel row can be any row among multiple pixel rows. Through the above implementation method, the first compensation parameter corresponding to the third pixel row can be determined based on the luminance parameters of some luminous sub-pixels of the third pixel row and the pixel rows adjacent to the third pixel row.

[0112] After determining the first compensation parameter corresponding to the third pixel row, the final compensation value corresponding to the third pixel row can be determined based on the first compensation parameter. After obtaining the final compensation value of the third pixel row, the data signal voltage of each luminous sub-pixel in the third pixel row can be compensated based on the final compensation value.

[0113] It should be noted that when there is a significant brightness difference between the image content displayed in the third pixel row and its adjacent next pixel row, the difference between the first typical value corresponding to the third pixel row and the second typical value corresponding to its adjacent next pixel row can reflect the large brightness difference between the two pixel rows. In this case, the final compensation value corresponding to the third pixel row is larger, and the brightness improvement effect of compensating the data signal voltage of each luminous sub-pixel in the third pixel row based on the final compensation value is more obvious. Conversely, if the brightness difference between the image content displayed in the third pixel row and its adjacent next pixel row is small, the final compensation value corresponding to the third pixel row is smaller, and the brightness improvement effect of compensating the data signal voltage of each luminous sub-pixel in the third pixel row based on the final compensation value is smaller.

[0114] In one optional implementation, when determining the final compensation value of the third pixel row based on the first compensation parameter corresponding to the third pixel row, the first compensation parameter can directly include the final compensation value. That is, the final compensation value of the third pixel row can be directly determined based on the brightness parameter compensation relationship.

[0115] In another implementation, the final compensation value of the third pixel row can be determined based on the current brightness level of the display panel and the first compensation parameter corresponding to the third pixel row. For example, a corresponding weighting coefficient can be determined based on the current brightness level of the display panel, and the final compensation value of the third pixel row can be obtained by multiplying the weighting coefficient and the first compensation parameter.

[0116] As an optional implementation, since the signal crosstalk phenomenon mentioned in the above analysis is not limited to a single pixel row, but may extend to multiple rows, for example, when there is a large brightness difference between two adjacent rows, signal crosstalk may occur in eight consecutive rows starting from these two rows, resulting in brighter white lines or dimmer black lines. In this case, providing a larger final compensation value only to the pixel row that produces the brightness difference cannot improve the signal crosstalk phenomenon in other pixel rows. Therefore, after determining the final compensation value corresponding to the third pixel row, a threshold judgment can be applied to the final compensation value. When the final compensation value reaches the compensation threshold, not only is the data signal voltage of each luminous sub-pixel in the third pixel row compensated using the final compensation value, but the data signal voltage of each luminous sub-pixel in multiple consecutive pixel rows after the third pixel row can also be compensated using the final compensation value to improve the signal crosstalk phenomenon in other pixel rows.

[0117] In the above embodiments, when there is a significant brightness difference between the third pixel row and its adjacent next pixel row, compensation can be performed on the data signal voltage of each luminous sub-pixel in the pixel row starting from the third pixel row, using the final compensation value. Compared to related technologies that start crosstalk compensation from the luminous pixel row with a large brightness difference, the above embodiments can perform compensation one row earlier.

[0118] In a single image frame, when the preceding pixel row is in the luminous stage, the following pixel row is in the non-luminous stage and can receive data signals from the data signal fan-out line. If there is a significant signal difference between this data signal and the data signal of the preceding pixel row, it will cause coupling effects on the power signal line, resulting in power supply voltage fluctuations, which in turn changes the brightness of each luminous sub-pixel in the third pixel row. When a large brightness change occurs between two adjacent pixel rows, crosstalk compensation can be applied to the previously lit third pixel row to mitigate the impact of power supply voltage fluctuations on the luminous sub-pixels in the third pixel row, thus ensuring the display effect of the third pixel row.

[0119] This application also provides another method, apparatus, device, and storage medium for crosstalk compensation of display panels. Figure 6 A flowchart illustrating a crosstalk compensation method for a display panel according to another embodiment of this application is shown. The display panel includes multiple pixel rows, and the crosstalk compensation method for the display panel includes:

[0120] S410, determine a first typical value and a second typical value based on the luminance parameters corresponding to the luminous sub-pixels of each of two adjacent pixel rows; wherein each of two adjacent pixel rows includes a first pixel row and a second pixel row, in a single luminous frame the first pixel row receives the scanning signal first, the first typical value is calculated based on the luminance parameters corresponding to the luminous sub-pixels of the first pixel row, and the second typical value is calculated based on the luminance parameters corresponding to the luminous sub-pixels of the second pixel row.

[0121] S420, determine the first compensation parameter corresponding to the first pixel row in each pair of adjacent pixel rows according to the brightness parameter compensation relationship, the first typical value and the second typical value; the first compensation parameter includes at least the data compensation values ​​corresponding to the first pixel row and at least (K-1) consecutive pixel rows thereafter; where K is greater than or equal to 2 and K is a positive integer;

[0122] S430, based on the data compensation value corresponding to the third pixel row in the first compensation parameter corresponding to the third pixel row, and the data compensation values ​​corresponding to the third pixel row in the first compensation parameter corresponding to the third pixel row for the consecutive (K-1) pixel rows before the third pixel row, determine the final compensation value of the third pixel row; the third pixel row is any row among multiple pixel rows; the final compensation value is used to compensate the data signal voltage of each luminous sub-pixel in the third pixel row.

[0123] The crosstalk compensation method for a display panel provided in this embodiment can be applied to a crosstalk compensation device for a display panel. This device can compensate for the data signal voltage of the light-emitting sub-pixels starting from the previous pixel row, based on the brightness parameter compensation relationship, when there is a large brightness difference in the displayed content of two adjacent pixel rows, thereby improving the signal crosstalk problem between the data signal lines and the power signal lines. The display panel can be a PC, television, smart terminal, or tablet computer, etc. This embodiment does not limit the specific form of the display panel.

[0124] In this embodiment, a first typical value and a second typical value are determined using the luminance parameters of some luminous sub-pixels in the first pixel row and the luminance parameters of some luminous sub-pixels in the second pixel row. Based on the luminance difference between the two pixel rows represented by the two typical values, a first compensation parameter corresponding to the first pixel row can be determined from the luminance parameter compensation relationship. This first compensation parameter includes the data compensation values ​​corresponding to the K consecutive pixel rows starting from this pixel row. If the luminance difference between the first pixel row and the second pixel row is large, the absolute value of the data compensation value corresponding to the K consecutive pixel rows starting from this pixel row is large; if the luminance difference between the two pixel rows is small, the K consecutive data compensation values ​​are small. Since the first compensation parameter corresponding to each pixel row includes the subsequent K consecutive pixel rows, the final compensation value of the first pixel row can be calculated based on the data compensation value corresponding to the first pixel row in the first compensation parameter corresponding to the first pixel row and the data compensation value corresponding to the first pixel row in the first compensation parameters corresponding to the (K-1) consecutive pixel rows preceding the first pixel row. After determining the final compensation value for the first pixel row, the data signal voltage of the light-emitting sub-pixels in that row can be adjusted based on the final compensation value to improve the signal crosstalk caused by the coupling effect of the power signal line and ensure the display effect of the display panel.

[0125] In S410, the display panel includes multiple pixel rows. When displaying an image on the display panel, the luminous brightness parameters corresponding to each luminous sub-pixel can be determined according to the image data of the image. When the scan signal line outputs the scan signal line line by line, the corresponding data signal is provided line by line through the data signal line according to the luminous brightness parameters of the luminous sub-pixels in each row.

[0126] When the luminance parameters of a row of luminous sub-pixels differ significantly from those of the previous row, the data voltage supplied to the luminous sub-pixels by the data signal line experiences a larger voltage change compared to the previous row. Because parasitic capacitance exists between the data signal lines and power signal lines within the display panel, a significant change in the data voltage on the data signal line will cause the power signal on the power signal line to fluctuate in the same direction due to the coupling effect of this parasitic capacitance. Figure 2 This illustrates the coupling effect of parasitic capacitance between the data signal line and the power signal line on the power supply voltage when the data voltage increases and decreases. For example... Figure 2 As shown, when the data voltage increases, the power signal line is affected by the synchronous coupling of parasitic capacitance, causing the power supply voltage to fluctuate in the same direction; that is, the power supply voltage increases briefly and then returns to its normal value. Conversely, when the data voltage decreases, the power signal line is affected by the synchronous coupling of parasitic capacitance, causing the power supply voltage to decrease briefly and then return to its normal value.

[0127] Taking an increase in data voltage as an example, during periods of power supply voltage variation, the driving current of the emitting sub-pixel will be affected by the voltage change, leading to higher luminance of the emitting sub-pixel. In this case, crosstalk compensation can be applied to the data signal voltage using a corresponding compensation voltage, ensuring that the actual voltage received by the emitting sub-pixel is the sum of the data voltage and the compensation voltage. When the emitting sub-pixel receives the compensated data voltage, it can compensate for the brightness changes caused by power supply voltage fluctuations, thereby reducing the brightness variations caused by power supply voltage fluctuations and improving signal crosstalk.

[0128] Figure 3 The image shown is affected by signal crosstalk. A single image frame displayed on the display panel includes a first image region 11, a second image region 12, and a third image region 13. The luminous intensity of a portion of the second image region 12 is significantly lower than that of the first image region 11 and the third image region 13. When the display panel provides data signals to the luminous sub-pixels row by row, due to the significant brightness difference between the last row of pixels in the first image region 11 and the first row of pixels in the second image region 12, the data signals provided by the data signal lines to adjacent rows of pixels also exhibit significant variations. At this time, the voltage change of the data signal will cause the parasitic capacitance between the data signal lines and the power signal lines to synchronously couple with the power supply voltage, resulting in voltage fluctuations in the power supply voltage. Similarly, at the boundary between the second image region 12 and the third image region 13, the data signal provided by the data signal lines will also experience significant voltage changes, resulting in voltage fluctuations in the power supply voltage.

[0129] The data voltage received by a light-emitting sub-pixel can be negatively correlated with its brightness. As the data voltage increases, the brightness of the sub-pixel gradually decreases, reaching zero when the data voltage reaches the black state. Therefore, as the data voltage on the data signal line increases, the brightness of the sub-pixels in that row gradually decreases compared to the previous row. However, due to the capacitive coupling between the data signal line and the power signal line, the power supply voltage increases due to synchronous coupling as the data voltage increases. The driving current of the light-emitting element in the sub-pixel is positively correlated with the power supply voltage; as the power supply voltage increases, the driving current increases accordingly, leading to an increase in the brightness of the sub-pixel. While the brightness of the sub-pixel should decrease as the data voltage increases, the power supply voltage fluctuations caused by signal crosstalk on the power signal line can actually increase the brightness of the sub-pixel, resulting in poor display quality.

[0130] like Figure 3As shown, at the boundary between the first image region 11 and the second image region 12, the emitting sub-pixels, driven by an increased power supply voltage, will produce a relatively bright line. Correspondingly, at the boundary between the second image region 12 and the third image region 13, the emitting sub-pixels, driven by a decreased power supply voltage, will produce a relatively dark bright line. The horizontal lines generated at the boundary between the first image region 11 and the second image region 12, and at the boundary between the second image region 12 and the third image region 13, represent signal crosstalk.

[0131] To mitigate the impact of signal crosstalk between data signal lines and power signal lines on image quality, the device compensates for the data signal voltage when providing it to each row of luminous sub-pixels. This compensates for brightness variations caused by power supply voltage fluctuations when the luminous sub-pixels receive the compensated data signal voltage, thereby reducing brightness variations resulting from signal crosstalk affecting the power supply voltage.

[0132] When displaying an image, taking two adjacent pixel rows as an example, these two adjacent pixel rows can include a first pixel row and a second pixel row. Based on the image data of the image frame, the luminance parameters corresponding to a portion of the luminous sub-pixels in the first pixel row and the luminance parameters corresponding to a portion of the luminous sub-pixels in the second pixel row can be determined. Within a single image frame, the luminous sub-pixels in the first pixel row receive the valid signal of the scan signal first, and the luminous sub-pixels in the second pixel row receive the valid signal of the scan signal subsequently.

[0133] The device can calculate the corresponding first typical value based on the luminance parameters of some luminous sub-pixels in the first pixel row, and calculate the corresponding second typical value based on the luminance parameters of some luminous sub-pixels in the second pixel row.

[0134] It is understandable that the first typical value can characterize the overall luminance parameter of the first pixel row, and the second typical value can characterize the overall luminance parameter of the second pixel row.

[0135] In S420, after determining the first typical value corresponding to the first pixel row and the second typical value corresponding to the second pixel row in every two adjacent pixel rows, a first compensation parameter for the first pixel row corresponding to the first and second typical values ​​can be determined according to the pre-stored brightness parameter compensation relationship. This first compensation parameter includes at least the data compensation values ​​corresponding to the first pixel row and at least (K-1) consecutive pixel rows thereafter. Where K is greater than or equal to 2 and K is a positive integer.

[0136] The method of determining the first typical value and the second typical value based on two adjacent pixel rows can be the implementation method exemplified in the above embodiments, and is not limited here.

[0137] In two adjacent pixel rows, the first pixel row to be lit is the first pixel row. Based on the first typical value and the second typical value corresponding to the two pixel rows, respectively, the first compensation parameter corresponding to the first pixel row can be obtained. For multiple pixel rows of the display panel, the first compensation parameter corresponding to the first pixel row to be lit can be determined for every two adjacent pixel rows. That is, based on the image data of a single illuminated frame, the first compensation parameter corresponding to each pixel row as the first pixel row in two adjacent pixel rows can be determined.

[0138] In one optional implementation, taking K as 8 as an example, when the first pixel row is the Nth row, the first compensation parameter for the Nth row, based on the first typical value and the second typical value, includes the data compensation values ​​corresponding to at least 8 consecutive pixel rows starting from the Nth row. That is, the first compensation parameter corresponding to the Nth row includes:

[0139] A(N)1;

[0140] A(N)2;

[0141] A(N)3;

[0142] A(N)4;

[0143] A(N)5;

[0144] A(N)6;

[0145] A(N)7;

[0146] A(N)8;

[0147] Where A(N)1 is the data compensation value corresponding to the Nth row, A(N)2 is the data compensation value corresponding to the N+1th row, ..., A(N)8 is the data compensation value corresponding to the N+7th row.

[0148] The values ​​of the eight data compensation values ​​included in the first compensation parameter mentioned above can be consistent or different, and this is not limited. In an optional implementation, since the voltage fluctuations generated by the power supply voltage on the power signal line will gradually decrease, the eight data compensation values ​​in the first compensation parameter can be gradually reduced. This ensures that the degree of data signal voltage compensation for the eight consecutive rows starting from the Nth row gradually decreases, avoiding the problem of overcompensation caused by excessive compensation strength in the final compensation value when the power supply voltage fluctuation decreases to a small extent.

[0149] When there is a significant brightness difference between the displayed content in the first pixel row and the displayed content in the second pixel row, the difference between the first typical value and the second typical value is also large. For example, the first pixel row is row N, the second pixel row is row N+1, and row N and row N+1 are the boundary between two display areas with different brightness levels. In this case, the data compensation values ​​corresponding to row N to row N+7 in the obtained first compensation parameters are all relatively large data compensation values. When compensating for the data signal voltage of rows N to N+7, the brightness of the luminous sub-pixels can be effectively compensated through larger data compensation values, improving the signal crosstalk phenomenon caused by the coupling effect of power supply voltage changes on data signal variations.

[0150] When the brightness difference between the displayed content in the first pixel row and the displayed content in the second pixel row is small, the first typical value and the second typical value are relatively close. For example, if the first pixel row is row N+1 and the second pixel row is row N+2, the first compensation parameter includes the data compensation value corresponding to row N+1 to row N+8. Since the first typical value and the second typical value are relatively close at this time, the data compensation values ​​corresponding to row N+1 to row N+8 are all relatively small data compensation values. That is, when determining the final compensation value corresponding to row N+1, the data compensation value in the first compensation parameter corresponding to row N has a larger impact on the final compensation value, while the data compensation value in the first compensation parameter corresponding to row N+1 has a smaller impact on the final compensation value.

[0151] Furthermore, taking row N+8 as an example, its corresponding final compensation value can be obtained from the first compensation parameters corresponding to row N+1 to row N+8. Since row N+1 and row N+8 are not the boundary between display areas of different brightness, the difference between the first typical value and the second typical value is small, resulting in smaller data compensation values ​​for row N+8 in each of the first compensation parameters. Therefore, the final compensation value corresponding to row N+8 is also small; that is, starting from row N+8, the compensation degree of the pixel row decreases compared to rows N to N+7. When K is 8, effective compensation of the data signal voltage for the 8 rows of luminous sub-pixels can be performed starting from the boundary between two display areas of different brightness, thereby improving the signal crosstalk phenomenon of these 8 rows of luminous sub-pixels.

[0152] It should be noted that the first pixel row in the above embodiments can be any row in the display panel. When the first pixel row is at the boundary between two display areas with different brightness, a large voltage compensation can be applied to the eight consecutive rows of light-emitting sub-pixels starting from the first pixel row. When the first pixel row is not at the boundary, a small voltage compensation can be applied to the eight consecutive rows of light-emitting sub-pixels starting from the first pixel row.

[0153] By adjusting the K value, for example, setting K to 4, 10, or 16, the number of pixel rows for crosstalk compensation can be set.

[0154] In S430, based on each pair of adjacent pixel rows, the first pixel row to be lit can be determined as the first pixel row, and the first compensation parameter corresponding to the first pixel row can be determined. After performing the above operation on multiple pixel rows of the display panel, the first compensation parameter corresponding to each pixel row in a single image frame can be obtained.

[0155] Taking the third pixel row as an example, the third pixel row can be any row among multiple pixel rows. Through the above implementation method, the first compensation parameter corresponding to the third pixel row can be determined based on the luminance parameters of some luminous sub-pixels of the third pixel row and the pixel rows adjacent to the third pixel row.

[0156] After determining the data compensation values ​​corresponding to at least K consecutive pixel rows included in the first compensation parameters corresponding to the third pixel row, the first compensation parameters corresponding to the preceding (K-1) rows of the third pixel row can be obtained, and the data compensation value corresponding to the third pixel row can be obtained from the (K-1) first compensation parameters corresponding to the preceding (K-1) rows. Based on the (K-1) data compensation values ​​corresponding to the third pixel row in the preceding (K-1) rows and the data compensation values ​​of the third pixel row in the first compensation parameters corresponding to the third pixel row, a total of K data compensation values, the final compensation value of the third pixel row can be calculated.

[0157] After obtaining the final compensation value for the third pixel row, the data signal voltage of each luminous sub-pixel in the third pixel row can be compensated based on the final compensation value. It should be noted that when there is a significant brightness difference between the image content displayed in the third pixel row and its adjacent next pixel row, the difference between the first typical value corresponding to the third pixel row and the second typical value corresponding to its adjacent next pixel row can reflect the significant brightness difference between the two adjacent pixel rows. Therefore, among the first compensation parameters obtained based on the significantly different first and second typical values, the data compensation values ​​corresponding to at least K consecutive pixel rows starting from the third pixel row are relatively high. That is, the device can effectively compensate for the data signal voltage of the luminous sub-pixels in each pixel row from the K consecutive pixel rows starting from the third pixel row. Compared to related technologies that start crosstalk compensation from the luminous pixel row with the largest brightness difference, the above embodiment can perform compensation one row earlier.

[0158] In a single image frame, when the preceding pixel row is in the luminous phase, the following pixel row is in the non-luminous phase and can receive data signals from the data signal fan-out line. If there is a significant signal difference between this data signal and the data signal of the preceding pixel row, it will cause coupling effects on the power signal line, resulting in power supply voltage fluctuations, which in turn changes the brightness of each luminous sub-pixel in the third pixel row. By performing crosstalk compensation on the third pixel row in advance when a large brightness change occurs in the second pixel row, the impact of power supply voltage fluctuations on each luminous sub-pixel in the third pixel row can be mitigated, ensuring the display effect of the third pixel row.

[0159] In one exemplary implementation, taking the third pixel row as the Nth row and K as 8, the first compensation parameters corresponding to the third pixel row include:

[0160] A(N)1;A(N)2;A(N)3;A(N)4;A(N)5;A(N)6;

[0161] A(N)7; A(N)8;

[0162] Wherein, when the third pixel is in the Nth row, the corresponding data compensation value is A(N)1; correspondingly, the data compensation value for the N+1th row is A(N)2; the data compensation value for the N+2nd row is A(N)3; ...; the data compensation value for the N+7th row is A(N)8.

[0163] Please refer to Figure 7 As an optional embodiment, the above-described S430 may include:

[0164] S510, when obtaining the first compensation parameters corresponding to the consecutive (K-1) pixel rows before the third pixel row, determine the data compensation values ​​corresponding to the third pixel row in the (K-1) first compensation parameters of the preceding (K-1) rows.

[0165] S520, determine the final compensation value of the third pixel row based on the K data compensation values ​​corresponding to the third pixel row from the K first compensation parameters corresponding to the third pixel row and the previous (K-1) rows respectively.

[0166] In this embodiment, the first compensation parameter corresponding to the third pixel row includes data compensation values ​​corresponding to at least K consecutive pixel rows starting from the third pixel row. Therefore, the (K-1) first compensation parameters corresponding to the (K-1) consecutive pixel rows preceding the third pixel row all involve the data compensation value of the third pixel row. That is, the first compensation parameter corresponding to the third pixel row and the first compensation parameters corresponding to the preceding (K-1) consecutive pixel rows, totaling K first compensation parameters, each contain K data compensation values ​​related to the third pixel row. Based on these K data compensation values, the final compensation value for the third pixel row can be calculated.

[0167] In S510, before obtaining the first compensation parameter corresponding to the third pixel row, the display panel can sequentially obtain the first compensation parameters corresponding to the consecutive pixel rows preceding the third pixel row. Since each first compensation parameter only includes the data compensation values ​​of K consecutive rows starting from the corresponding pixel row, the first compensation parameter associated with the third pixel row is (K-1) first compensation parameters corresponding to the consecutive (K-1) pixel rows preceding the third pixel row.

[0168] After determining the (K-1) first compensation parameters corresponding to the (K-1) pixel rows, the data compensation value corresponding to the third pixel row in each first compensation parameter can be obtained.

[0169] In one exemplary implementation, the preceding (K-1) rows of row N are row (N-1), row (N-2), ..., row (N-K+1). Taking the row preceding the third pixel row, i.e., row (N-1), as an example, after determining the first typical value of row (N-1) and the second typical value of row N, a first compensation parameter corresponding to row (N-1) can be determined based on the brightness parameter compensation relationship. This first compensation parameter includes:

[0170] A(N-1)1;A(N-1)2;A(N-1)3;A(N-1)4;A(N-1)5;A(N-1)6;A(N-1)7;A(N-1)8;

[0171] Wherein, A(N-1)1 is the data compensation value corresponding to the (N-1)th row in the first compensation parameter corresponding to the (N-1)th row, and A(N-1)2 is the data compensation value corresponding to the next row after the (N-1)th row, that is, the Nth row.

[0172] The display panel can sequentially obtain the first compensation parameters corresponding to each pixel row. Therefore, before obtaining the first compensation parameters corresponding to the Nth row, the display panel has already obtained and stored the first compensation parameters corresponding to the (N-1)th row.

[0173] Similarly, the first compensation parameter corresponding to row (N-2) includes:

[0174] A(N-2)1;A(N-2)2;A(N-2)3;A(N-2)4;A(N-2)5;A(N-2)6;A(N-2)7;A(N-2)8;

[0175] Where A(N-2)3; is the data compensation value corresponding to the Nth row in the first compensation parameter corresponding to the (N-2)th row.

[0176] When K is 8, the data compensation values ​​corresponding to the Nth row among the first compensation parameters corresponding to the (N-3)th row to the (N-8+1)th row are as follows:

[0177] A(N-3)4;A(N-4)5;A(N-5)6;A(N-6)7;A(N-7)8;

[0178] From the above analysis, it can be seen that when the third pixel is in the Nth row, the data compensation values ​​corresponding to the Nth row among the (K-1) first compensation parameters in the preceding (K-1) rows are as follows:

[0179] A(N-1)2;A(N-2)3;A(N-3)4;A(N-4)5;A(N-5)6;A(N-6)7;A(N-7)8;

[0180] In S520, after determining the data compensation value corresponding to the third pixel row in the first compensation parameter corresponding to the third pixel row, and the data compensation value corresponding to the third pixel row in the (K-1) first compensation parameters corresponding to the previous (K-1) rows respectively, the final compensation value of the third pixel row can be calculated based on the K data compensation values.

[0181] In one optional implementation, after determining the K data compensation values, the device can use the sum of the K data compensation values ​​as the final compensation value of the third pixel row, or the average of the K data compensation values ​​as the final compensation value of the third pixel row, or select the largest or smallest data compensation value from the K data compensation values ​​as the final compensation value of the third pixel row, without any limitation.

[0182] As an optional embodiment, the formula for calculating the final compensation value can be:

[0183]

[0184] Where V is the final compensation value, a i Here, A(N+1-i) represents the weighting coefficient, N is the row number of the third pixel, and A(N+1-i) represents the weighting coefficient. iThis refers to the data compensation value corresponding to the Nth row in the first compensation parameter corresponding to the (N+1-i)th row.

[0185] Understandably, taking the third pixel row as the Nth row as an example, when K=8, the formula for calculating the final compensation value can be:

[0186] V=(a1*A(N)1)+(a2*A(N-1)2)+(a3*A(N-2)3)

[0187] +(a4*A(N-3)4)+(a5*A(N-4)5)+(a6*A(N-5)6)

[0188] +(a7*A(N-6)7)+(a8*A(N-7)8);

[0189] The above weighting coefficient a i All values ​​can be set to 1, meaning the final compensation value V is the average of all data compensation values. The aforementioned weighting coefficient a... i Different constants can also be set.

[0190] Among the K first compensation parameters corresponding to the Nth row and the (K-1) consecutive rows preceding the Nth row, the closer the first compensation parameter is to the Nth row, the higher the accuracy of its corresponding data compensation value. Therefore, the aforementioned weighting coefficient a i It can also be set to have a negative correlation with i, that is, the larger i is, the higher the corresponding weight coefficient a. i The smaller the value, the less significant the impact of the data compensation value in the first compensation parameter corresponding to the (N+1-i)th row on the final compensation value.

[0191] As an optional embodiment, the data compensation value corresponding to a single pixel row includes the data compensation sub-values ​​corresponding to the emitting sub-pixels of different emitting colors.

[0192] It is understandable that the data compensation values ​​corresponding to light-emitting sub-pixels of different light-emitting colors are different under the same first compensation parameter. Therefore, the data compensation value corresponding to a single pixel row includes the data compensation sub-values ​​corresponding to light-emitting sub-pixels of different light-emitting colors.

[0193] Taking the third pixel row as the Nth row as an example, when K is 8, the first compensation parameter corresponding to the Nth row can include:

[0194] A(N) 1R A(N) 1G A(N) 1G ;

[0195] A(N) 2R A(N) 2G A(N) 2G ;

[0196] A(N) 3R A(N) 3G A(N) 3G ;

[0197] A(N) 4R A(N) 4G A(N) 4G ;

[0198] A(N) 5R A(N) 5G A(N) 5G ;

[0199] A(N) 6R A(N) 6G A(N) 6G ;

[0200] A(N) 7R A(N) 7G A(N) 7G ;

[0201] A(N) 8R A(N) 8G A(N) 8G ;

[0202] Where, A(N) 1R A(N) is the data compensation sub-value for the red luminous sub-pixel corresponding to the Nth row. 1G And A(N) 1B The data compensation values ​​for the green and blue luminous sub-pixels corresponding to the Nth row, respectively.

[0203] Based on the data compensation sub-values ​​of the K red emitting sub-pixels corresponding to the Nth row and the K first compensation parameters of the preceding (K-1) rows, the final compensation value V of the red emitting sub-pixels in the Nth row can be calculated. R Similarly, based on the data compensation values ​​of the K green luminous sub-pixels and the K blue luminous sub-pixels, the final compensation value V of the green luminous sub-pixels in the Nth row can be calculated. G And the final compensation value V for the blue emitting sub-pixel in row N. B .

[0204] The final compensation value V corresponding to each light-emitting sub-pixel of the emitted color in the Nth row is determined. R V G and V B Then, the data signal voltage of the emitting sub-pixels of the corresponding light-emitting colors can be compensated according to each final compensation value.

[0205] Please refer to Figure 8 As an optional embodiment, the display panel may include a plurality of light-emitting sub-pixels 10 arranged in an array. The plurality of light-emitting sub-pixels 10 in the same row are connected to the same scan signal line, and every two adjacent columns of light-emitting sub-pixels 10 are connected to the same data signal fan-out line. Figure 8 A schematic diagram of the structure of some light-emitting sub-pixels 10 in the display panel is shown. 1H to 4H are four consecutive pixel rows, G1 to G4 are scan signal lines connected to the four pixel rows, S1 is a data signal fan-out line, the light-emitting sub-pixel 10 labeled 1 is the light-emitting sub-pixel in the odd-numbered column, and the light-emitting sub-pixel 10 labeled 2 is the light-emitting sub-pixel in the even-numbered column.

[0206] The same data signal fanout line can be time-division multiplexed to provide data signals to two adjacent columns of luminous sub-pixels 10. Taking two adjacent rows of luminous sub-pixels 10, totaling four luminous sub-pixels 10, as an example... Figure 8 As shown, in two light-emitting sub-pixels 10 in the same row, the light-emitting sub-pixel 10 at the odd-numbered position receives the data signal first, and the light-emitting sub-pixel 10 at the even-numbered position receives the data signal later. Therefore, when there is a significant brightness difference between two adjacent light-emitting sub-pixels 10 in two rows, the signal voltage of the data signal received by the even-numbered light-emitting sub-pixel 10 in the preceding row will differ significantly from the signal voltage of the data signal received by the odd-numbered light-emitting sub-pixel 10 in the following row. This voltage change on the data signal line will cause the power signal line to be affected by parasitic capacitance coupling, resulting in fluctuations in the power supply voltage.

[0207] By obtaining the luminance parameters of the even-numbered columns of the luminous sub-pixels 10 in the first pixel row and the odd-numbered columns of the luminous sub-pixels 10 in the second pixel row, respectively, in adjacent first pixel rows and second pixel rows, a first typical value and a second typical value can be calculated. The difference between the first typical value and the second typical value can characterize the brightness difference between the first pixel row and the second pixel row. Based on the brightness difference, the corresponding first compensation parameter can be determined from the brightness parameter compensation relationship, thereby compensating for the capacitive coupling generated between the data signal line and the power signal line, improving the signal crosstalk phenomenon caused by voltage fluctuations in power supply voltage synchronization coupling, and ensuring the display effect of the display panel.

[0208] Please continue to refer to Figure 8As an optional embodiment, the display panel may include multiple multiplexing modules 20. The input terminals of the multiplexing modules 20 are connected to the data signal fan-out line S1. Each multiplexing module 20 includes four output terminals. In two adjacent columns of light-emitting sub-pixels 10, one column of light-emitting sub-pixels 10 is alternately connected to two of the output terminals, and the other column of light-emitting sub-pixels 10 is alternately connected to the other two output terminals. In this embodiment, the display panel may also include multiple multiplexing modules 20, each multiplexing module 20 being connected to a data signal fan-out line S1.

[0209] Taking a single multiplexing module 20 as an example, the multiplexing module 20 may include four MUX transistors. The input terminal of the multiplexing module 20 is connected to a data signal fan-out line S1. The four output terminals of the multiplexing module 20 are respectively connected to the input terminal through the four MUX transistors. In two adjacent columns of light-emitting sub-pixels 10, one column of light-emitting sub-pixels 10 is alternately connected to two output terminals MUX1 and MUX3, and the other column of light-emitting sub-pixels 10 is alternately connected to the other two output terminals MUX2 and MUX4. By controlling the multiplexing signal to connect the input terminal of the multiplexing module 20 to the four output terminals in sequence, time-division multiplexing of the data signal can be realized, thereby providing data signals to the two columns of light-emitting sub-pixels 10 through a data signal fan-out line S1.

[0210] Please refer to Figure 9 , Figure 9 The diagram shows the signal timing of the data signal. Taking the case where the odd-numbered columns of the luminous sub-pixels 10 in each row of luminous sub-pixels 10 receive the data signal first, when MUX1, MUX2, MUX3, and MUX4 are turned on sequentially, the data signal fan-out line S1 can respectively... Figure 8 Four signal traces provide data signals to write data signals to the two columns of luminous sub-pixels 10. SCK1 and SCK2 are alternately conducting clock signals, and the progressive scan signals correspond to SCK1 and SCK2. When MUX2 is active, the even-numbered luminous sub-pixels 10 in the first row 1H receive the data signal; when MUX3 is active, the odd-numbered luminous sub-pixels 10 in the second row 2H receive the data signal. At the boundary between the first row 1H and the second row 2H, which are display areas with different brightness levels, the data signal provided by MUX3 changes significantly compared to the data signal from MUX2. During the Ct time period, the power supply voltage will fluctuate due to parasitic capacitance coupling, causing signal crosstalk.
