[0062] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present application.

[0066] It should be noted that, in the absence of conflict, different features in the embodiments of the present application may be combined with each other.

[0067] The inventors have found that the scanning signal lines in the display panel can output scanning signals row by row, and provide scanning signals to the light-emitting sub-pixels in each row 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 line starts from the starting pixel row of the area, and will provide the light-emitting sub-pixels with brightness differences with data signal voltages different from those of the light-emitting sub-pixels in other pixel rows, which will cause a sudden change in the data voltage on the data signal line.

[0068] Due to the coupling capacitance between the data signal line and the power signal line, when the voltage of the data signal line suddenly changes, the power voltage on the power signal line will be affected by the synchronous coupling and cause voltage fluctuation, thereby causing signal crosstalk and affecting the display effect.

[0069] In view of this, this embodiment provides a solution that can solve the above-mentioned problem, and the solution provided by this embodiment is described in detail below.

[0075] In another possible implementation, please refer again to Figure 2 When the wiring architecture of the display panel is a single data line architecture, the light-emitting sub-pixels 100 corresponding to every two adjacent pixel columns are connected to the same multi-way selection module 200 through two data lines, and the first pixel row and the second pixel row can be two adjacent pixel rows, and no other pixel rows are included between the first pixel row and the second pixel row.

[0076] Please refer to Figure 3 , Figure 3 The schematic flow chart of the crosstalk compensation method for a display panel provided by the present embodiment is exemplified. The crosstalk compensation method for a display panel may include the following steps.

[0077] Step S100, determining the first difference data corresponding to the pixel row group based on the voltage data corresponding to each light-emitting sub-pixel 100 in the odd-numbered columns of the first pixel row and the second pixel row in the same pixel row group, and determining the second difference data corresponding to the pixel row group based on the voltage data corresponding to each light-emitting sub-pixel 100 in the even-numbered columns of the first pixel row and the second pixel row.

[0078] In a possible implementation, when determining the first difference data corresponding to the pixel row group based on the voltage data corresponding to each light-emitting sub-pixel 100 in the odd-numbered columns of the first pixel row and the second pixel row in the same pixel row group, the first typical value corresponding to the first pixel row can be determined based on the voltage data corresponding to each light-emitting sub-pixel 100 in the odd-numbered columns of the first pixel row, and the second typical value corresponding to the second pixel row can be determined based on the voltage data corresponding to each light-emitting sub-pixel 100 in the odd-numbered columns of the second pixel row, and the first difference data corresponding to the pixel row group can be obtained by comparing the first typical value with the second typical value.

[0079] Specifically, the first typical value corresponding to the first pixel row can be the sum of the voltage data corresponding to each light-emitting sub-pixel 100 in the odd columns of the first pixel row, and the second typical value corresponding to the second pixel row can be the sum of the voltage data corresponding to each light-emitting sub-pixel 100 in the odd columns of the second pixel row. By comparing the first typical value and the second typical value, the difference between the first typical value and the second typical value can be obtained as the first difference data.

[0080] When determining the second difference data corresponding to the pixel row group based on the voltage data corresponding to each light-emitting sub-pixel 100 in the even columns of the first pixel row and the second pixel row, the third typical value corresponding to the first pixel row can be determined based on the voltage data corresponding to each light-emitting sub-pixel 100 in the even columns of the first pixel row, and the fourth typical value corresponding to the second pixel row can be determined based on the voltage data corresponding to each light-emitting sub-pixel 100 in the even columns of the second pixel row, and the first difference data corresponding to the pixel row group can be obtained by comparing the third typical value with the fourth typical value.

[0081] Specifically, the third typical value corresponding to the first pixel row can be the sum of the voltage data corresponding to each light-emitting sub-pixel 100 in the even columns of the first pixel row, and the fourth typical value corresponding to the second pixel row can be the sum of the voltage data corresponding to each light-emitting sub-pixel 100 in the even columns of the second pixel row. By comparing the third typical value and the fourth typical value, the difference between the third typical value and the fourth typical value can be obtained as the first difference data.

[0082] In another possible implementation, when determining the first difference data corresponding to the pixel row group based on the voltage data corresponding to each light-emitting sub-pixel 100 in the odd-numbered columns of the first pixel row and the second pixel row in the same pixel row group, the voltage data corresponding to each light-emitting sub-pixel 100 in the odd-numbered columns of the first pixel row can be compared with the voltage data corresponding to each light-emitting sub-pixel 100 in the odd-numbered columns of the second pixel row, and the first difference data can be calculated based on the comparison result.

[0083] Specifically, by comparing the voltage data corresponding to each light-emitting sub-pixel 100 located in the same odd column of the first pixel row and the second pixel row, the difference value of the voltage data of each odd column of the first pixel row and the second pixel row can be obtained, and the value obtained by adding each difference value can be used as the first difference data.

[0084] When determining the second difference data corresponding to the pixel row group based on the voltage data corresponding to each light-emitting sub-pixel 100 in the even columns of the first pixel row and the second pixel row, the voltage data corresponding to each light-emitting sub-pixel 100 in the even columns of the first pixel row can be compared with the voltage data corresponding to each light-emitting sub-pixel 100 in the even columns of the second pixel row, and the second difference data can be calculated based on the comparison result.

[0085] Specifically, by comparing the voltage data corresponding to each light-emitting sub-pixel 100 located in the same even column of the first pixel row and the second pixel row, the difference value of the voltage data of each even column of the first pixel row and the second pixel row can be obtained, and the value obtained by adding each difference value can be used as the second difference data.

[0086] Step S200 , determining first compensation data and second compensation data corresponding to the pixel row group according to the first difference data and the second difference data respectively.

[0087] In this embodiment, the first difference data and the second difference data obtained in step S100 may be indexed from a preset lookup table LUT to obtain the corresponding first compensation data and second compensation data.

[0088] Step S300 , calculating a target compensation value of a target pixel row according to the first compensation data and the second compensation data corresponding to the pixel row group, and compensating the voltage of each light-emitting sub-pixel 100 in the target pixel row based on the target compensation value.

[0089] In this embodiment, the target pixel row can be any row of multiple pixel rows. The first compensation data and the second compensation data of the pixel row group obtained by step S200 can be used to calculate the target compensation value. After determining the target compensation value, the voltage of each light-emitting sub-pixel 100 in the target pixel row can be compensated and adjusted according to the target compensation value to improve signal crosstalk.

[0090] Based on the above design, in the crosstalk compensation method of the display panel provided in this embodiment, the compensation data of the odd columns and the even columns are calculated respectively through the voltage data of each light-emitting sub-pixel 100, and the target compensation value is obtained based on the compensation data of the odd columns and the even columns. The signal crosstalk phenomenon can be accurately compensated, thereby improving the display effect of the display panel.

[0091] In one possible implementation, please refer again to Figure 1 In the same pixel column, the two most adjacent light-emitting sub-pixels 100 are respectively connected to different data lines, and an interval pixel row is included between the first pixel row and the second pixel row.

[0094] The first ends of the four gate switches are connected to the same multiplexing line, the second ends of the four gate switches are respectively connected to different data lines, and the control ends of the four gate switches are respectively connected to different gate control signal lines.

[0095] In this embodiment, when the wiring architecture of the display panel is a dual data line architecture, the same multiplexing line can be connected to two adjacent columns of light-emitting sub-pixels 100, and data signals are provided to the two columns of light-emitting sub-pixels 100 in a time-division multiplexing manner. The display panel may include a plurality of multiplexing modules 200, each of which is connected to a multiplexing line, and each of which may include four gating switches. In the light-emitting sub-pixels 100 corresponding to two adjacent pixel columns, the light-emitting sub-pixels 100 of one pixel column are alternately connected to two of the gating switches MUX1 and MUX3, and the light-emitting sub-pixels 100 of the other pixel column are alternately connected to the other two gating switches MUX2 and MUX4.

[0096] Please refer to Figure 4 , Figure 4 1 shows a schematic diagram of the signal timing of the data signal. Taking the case that the light-emitting sub-pixels 100 in the odd columns receive the data signal first in each row of light-emitting sub-pixels 100, when MUX1, MUX2, MUX3 and MUX4 are turned on in sequence, the multiplexing lines can be respectively Figure 1 The four data lines in provide data signals to realize the writing of data signals to two columns of light-emitting sub-pixels 100. The SCK1 signal and the SCK2 signal are clock signals that are alternately turned on, and the scanning signals driven row by row correspond to the SCK1 signal and the SCK2 signal. When MUX2 is at an effective level, the light-emitting sub-pixels 100 of the even columns of the first row 1H receive data signals, and when MUX3 is at an effective level, the light-emitting sub-pixels 100 of the odd columns of the second row 2H receive data signals.

Taking the case that the light-emitting sub-pixels 100 in the odd columns receive the data signal first in each row of light-emitting sub-pixels 100, when MUX1 and MUX2 are turned on in sequence, the multiplexing lines can be respectively Figure 1 The two data lines in provide data signals to realize data signal writing of two columns of light-emitting sub-pixels 100. The SCK1 signal and the SCK2 signal are clock signals that are alternately turned on, and the scanning signal driven row by row corresponds to the SCK1 signal and the SCK2 signal. When MUX1 is at an effective level, the light-emitting sub-pixels 100 of the odd columns of the first row 1H receive data signals, and when MUX2 is at an effective level, the light-emitting sub-pixels 100 of the odd columns of the first row 1H receive data signals.

[0103] In one possible implementation, when calculating the target compensation value of the target pixel row based on the first compensation data and the second compensation data, the target compensation value of the target pixel row can be calculated based on the first compensation data and the second compensation data corresponding to multiple pixel row groups before the target pixel row and adjacent to the target pixel row.

[0104] In this embodiment, each pixel row group can correspond to a first compensation data and a second compensation data. When calculating the target compensation value, a certain number of compensation data can be selected according to the display effect of each light-emitting sub-pixel 100 in the target pixel row, and the target compensation value of the target pixel row can be calculated based on the selected compensation data.

[0105] In one possible implementation, see Figure 6 When calculating the target compensation value of the target pixel row according to the first compensation data and the second compensation data corresponding to a plurality of pixel row groups before the target pixel row and adjacent to the target pixel row, step S200 may include the following sub-steps.

[0106] Step S210 , determining weight coefficients corresponding to a plurality of pixel row groups before the target pixel row and adjacent to the target pixel row.

[0107] In this embodiment, the pixel row group before the target pixel row and adjacent to the target pixel row can be determined according to the number of selected compensation data and the target pixel row, and the weight coefficient corresponding to each selected compensation data can be obtained.

[0108] Among them, the first compensation data and the second compensation data of each pixel row group can respectively correspond to a weight coefficient, and the values ​​of different weight coefficients may be different. The closer the pixel row group is to the target pixel row, the greater the influence of the first compensation data and the second compensation data corresponding to the pixel row group on the target compensation value. Therefore, the closer the pixel row group is to the target pixel row, the larger the weight coefficient corresponding to the pixel row group is.

[0109] Step S220 , calculating a target compensation value of a target pixel row according to weight coefficients corresponding to a plurality of pixel row groups, the first compensation data, and the second compensation data.

[0110] In this embodiment, the target compensation value of the target pixel row may be calculated according to the weight coefficient obtained in step S210 and the first compensation data and the second compensation data obtained in step S100.

[0111] In a possible implementation, the target compensation value V of the target pixel row may be calculated in the following manner:

[0112]

[0113] Wherein, i represents the number of the pixel row group before the target pixel row and adjacent to the target pixel row. The smaller i is, the closer the pixel row group is to the target pixel row. i represents the first compensation data corresponding to the i-th pixel row group, B i represents the second compensation data corresponding to the i-th pixel row group, α i1 , α i2 represents the weight coefficient corresponding to the i-th pixel row group, N represents the number of pixel row groups before the target pixel row and adjacent to the target pixel row, and N is greater than or equal to 2.

[0114] For example, the number N of pixel row groups may be 4, and the four pixel row groups may correspond to four first compensation data and four second compensation data, respectively. Then, the target compensation value V of the target pixel row=α 11 A 1 +α 12 B 1 +α 21 A 2 +α 22 B 2 +α 31 A 3 +α 32 B 3+α 41 A 4 +α 42 4.

[0115] In a possible implementation, when the wiring architecture of the display panel is a dual data line architecture, if the target pixel row is the eighth pixel row, the first pixel row and the second pixel row corresponding to the four pixel row groups may be the seventh pixel row and the ninth pixel row, the sixth pixel row and the eighth pixel row, the fifth pixel row and the seventh pixel row, and the fourth pixel row and the sixth pixel row, respectively.

[0116] In another possible implementation, when the wiring architecture of the display panel is a single data line architecture, if the target pixel row is the fifth pixel row, the first pixel row and the second pixel row corresponding to the four pixel row groups may be the fourth pixel row and the fifth pixel row, the third pixel row and the fourth pixel row, the second pixel row and the third pixel row, and the first pixel row and the second pixel row, respectively.

[0117] In one possible implementation, before determining the first difference data corresponding to the pixel row group based on the voltage data corresponding to each light-emitting sub-pixel 100 in the odd-numbered columns of the first pixel row and the second pixel row in the same pixel row group, and determining the second difference data corresponding to the pixel row group based on the voltage data corresponding to each light-emitting sub-pixel 100 in the even-numbered columns of the first pixel row and the second pixel row, the voltage data corresponding to each light-emitting sub-pixel 100 of a frame of image to be displayed can also be obtained.

[0118] When the first compensation data and the second compensation data corresponding to the pixel row group are determined according to the first difference data and the second difference data, the first compensation data and the second compensation data corresponding to each pixel row group can be determined according to the first difference data and the second difference data.

[0119] In this embodiment, the first difference data and the second difference data corresponding to each pixel row group can be determined according to the voltage data corresponding to each light-emitting sub-pixel 100, so that the first compensation data and the second compensation data corresponding to each pixel row group can be obtained from the preset lookup table LUT according to the first difference data and the second difference data corresponding to each pixel row group.
