It will be apparent to those skilled in the art that various modifications and variations can be made in the present application without departing from the spirit or scope of the application. Accordingly, it is intended that the present application covers the modifications and variations of this application provided they come within the scope of the appended claims (the claims) and their equivalents. The embodiments provided by the embodiments of the present application may be combined with each other without contradiction.
Before describing the technical solution provided by the embodiments of the present application, in order to facilitate understanding of the embodiments of the present application, the present application firstly specifically describes the problems existing in the related art:
As described above, the present inventors have found that there is a problem of crosstalk of a display panel in the related art. In the field of display technology, coupling interference of display DATA voltage (DATA voltage) to power supply voltage PVDD is unavoidable due to the influence of wiring process design in an OLED display module. The interference causes a Line Crosstalk (Line Crosstalk) phenomenon when the OLED display module displays some pictures.
Referring to fig. 1 in particular, fig. 1 is a schematic diagram of a line crosstalk of a display panel according to an embodiment of the present application. As shown in fig. 1, when the DATA voltage at the junction of the white screen and the black screen on the display panel jumps, the PVDD voltage will jump at the same time due to the parasitic capacitance of the PVDD and the DATA. If the DATA voltage value increases, the PVDD voltage value jumps high; if the DATA voltage value decreases, the PVDD voltage value jumps low.
See fig. 2 and 3 for specific linear line crosstalk. Fig. 2 is a schematic representation of line crosstalk of a display panel according to an embodiment of the present application, as shown in fig. 2, when the upper edge PVDD of the black frame jumps upward, the voltage difference between the DATA writing line and the PVDD increases, the boundary between the black frame and the white frame is represented as a bright line, when the lower edge PVDD of the black frame jumps downward, the voltage difference between the DATA writing line and the PVDD increases, the boundary between the black frame and the white frame is represented as a dark line, and the display effect of the bright line and the dark line on the display panel is as shown in fig. 2.
Fig. 3 is a schematic representation of line crosstalk of another display panel according to an embodiment of the present application. As shown in fig. 3, when the upper edge PVDD of the white frame jumps downward, the voltage difference between the DATA writing line and the PVDD is reduced, the boundary between the black frame and the white frame appears as a dark line, and when the lower edge PVDD of the white frame jumps upward, the voltage difference between the DATA writing line and the PVDD is increased, the boundary between the black frame and the white frame appears as a bright line, and the display effect of the bright line and the dark line on the display panel in this case is shown in fig. 3.
In order to solve the problem of poor display effect of the display panel caused by line crosstalk, the prior art adopts the technical scheme that the DATA voltages corresponding to the bright line and the dark line are determined, the difference between the two DATA voltages is calculated, the compensation intensities respectively corresponding to the bright line and the dark line are determined according to the voltage difference, and compensation is performed according to the corresponding compensation intensities. However, under such a compensation scheme, the display panel line crosstalk phenomenon still cannot be well improved, and the compensation effect is poor. In view of this, how to effectively improve the phenomenon that the OLED display module is prone to line crosstalk when displaying the picture becomes a technical problem to be solved.
In view of the above-mentioned research of the inventor, in order to solve the problems in the prior art, embodiments of the present application provide a compensation method, apparatus, device, and storage medium for a display panel. It should be noted that the examples provided by the present application are not intended to limit the scope of the present disclosure.
The compensation method of the display panel provided by the embodiment of the application is described below.
Referring to fig. 4 first, fig. 4 is a schematic structural diagram of a display panel according to an embodiment of the present application, where the display panel may be an AMOLED, an OLED, or others. Those skilled in the art will appreciate that in other implementations of the application, the display panel may also be a micro light emitting diode display panel, a quantum dot display panel, or the like.
As shown in fig. 4, the display panel may include adjacent first and second pixel rows 10 and 20, and the first and second pixel rows 10 and 20 may be arranged at intervals in the first direction Y, and any one of the pixel rows may include a plurality of pixel units extending in the second direction X. In one data scanning cycle, the first pixel row 10 is scanned before the second pixel row 20. It should be noted that in the field of display panel technology, the display panel includes a plurality of rows of pixel circuits, and a scanning signal for controlling writing of data in a display frame will generally scan each row of pixel circuits line by line in sequence, and the scanning sequence of the first pixel row 10 and the second pixel row 20 in the same display frame are first performed.
The difference between the sum of the luminance parameters of the plurality of pixel units in the first pixel row 10 and the sum of the luminance parameters of the plurality of pixel units in the second pixel row is greater than a target threshold. The light emitting luminance parameter herein may specifically be, for example, a data voltage (Vdata), a gamma register value, a gray scale value to be displayed, a luminance value to be displayed, or the like.
For example, before displaying a frame of image, it is generally necessary to obtain image parameters (such as a gray level value or a brightness value of an image) of the image to be displayed, and then determine the actually required light-emitting brightness parameters of each pixel unit in each pixel row in the display panel according to the image parameters. Based on this, the first pixel row 10 and the second pixel row 20 may be determined after the screen parameters of the screen to be displayed are acquired and in the period of time in which the screen to be displayed is formally displayed.
Taking the light emitting luminance parameter as the data voltage Vdata as an example, the difference between the sum of the light emitting luminance parameters of the plurality of pixel units in the first pixel row 10 and the sum of the light emitting luminance parameters of the plurality of pixel units in the second pixel row 20 is greater than the target threshold, and the difference between the sum of the data voltages Vdata of the plurality of pixel units in the first pixel row 10 and the sum of the data voltages Vdata of the plurality of pixel units in the second pixel row 20 may be greater than the target threshold. In this case, the data voltage Vdata of the second pixel row is compared with the first pixel row, and the second pixel row is the pixel row where the line crosstalk (bright line, dark line) is located.
It should be added that the target threshold may be specifically set in combination with experience related to line crosstalk or actual debug requirements, and the present application is not limited thereto.
Fig. 5 is a flowchart illustrating a compensation method of a display panel according to an embodiment of the application. As shown in fig. 5, the compensation method of the display panel may include the steps of:
s510, acquiring an initial compensation value of a pixel unit in a second pixel row; the initial compensation value is obtained based on the luminous brightness parameter of the pixel units in the first pixel row and the luminous brightness parameter of the pixel units in the second pixel row;
s520, determining a target area where the second pixel row is located according to the luminous brightness parameters of the pixel units in the second pixel row;
s530, determining the compensation weight value of the pixel unit in the second pixel row according to the corresponding relation between the target area and the compensation weight value;
s540, compensating the luminous brightness parameters of the M target pixel units in the second pixel row based on the initial compensation value and the compensation weight value to obtain compensated luminous brightness parameters of the M target pixel units; m is a positive integer.
As can be seen from the foregoing description, in the compensation method for a display panel provided by the embodiment of the present application, the second pixel row is a pixel row having linear line crosstalk, and when the line crosstalk occurring in the second pixel row is specifically compensated, the target area where the second pixel row is located is determined by acquiring the initial compensation value of the pixel unit in the second pixel row and according to the light-emitting brightness parameter of the pixel unit in the second pixel row. And then determining the compensation weight value of the pixel unit in the second pixel row according to the corresponding relation between the target area and the compensation weight value. And finally, compensating the luminous brightness parameter of the target pixel unit in the second pixel row based on the initial compensation value and the compensation weight value to obtain the compensated luminous brightness parameter of the target pixel unit.
Compared with the prior art, the compensation method of the display panel of the embodiment of the application considers that the Line cross-talk degree caused by the same DATA voltage difference at different positions on the display panel is different, and if the same DATA voltage difference is compensated to the same degree according to the prior art, the Line Crosstalk compensation effect is poor. Therefore, the embodiment of the application determines the compensation weight value of the pixel unit in the second pixel row by determining the target area where the second pixel row is located and then according to the corresponding relation between the target area and the compensation weight value. Therefore, by introducing the compensation weight value corresponding to the target area where the second pixel Line is located, the second pixel Line in different area positions can be subjected to differential compensation, so that the Line cross compensation effect is improved, the problem of uneven display brightness of the display panel can be effectively and fully improved, and the display effect of the display panel can be effectively improved.
The following describes the specific embodiments of steps 510 to 540.
In a specific implementation in S510, the initial compensation value of the pixel unit in the second pixel row may be determined based on the light emitting luminance parameter of the pixel unit in the first pixel row and the light emitting luminance parameter of the pixel unit in the second pixel row.
For example, the difference between the sum of the luminance parameters of the pixel units in the first pixel row and the sum of the luminance parameters of the pixel units in the second pixel row may be determined according to the luminance parameters of the pixel units in the first pixel row and the luminance parameters of the pixel units in the second pixel row, and then the initial compensation value of the pixel units in the second pixel row under the current difference is determined according to the corresponding relationship between the different difference and the initial compensation value.
In determining the initial compensation value, the above-mentioned light emitting luminance parameter may specifically be, for example, a data voltage (Vdata), a gamma register value, a gray-scale value to be displayed, a luminance value to be displayed, or the like.
The correspondence between the difference and the initial compensation value may be set in advance according to actual compensation experience, for example, the larger the difference is, the larger the compensation intensity for the second pixel row is, and accordingly, the larger the initial compensation value for the pixel unit in the second pixel row may be set, which is not strictly limited in the present application.
In S520, in a specific implementation, a target area where the second pixel row is located is determined according to the light-emitting brightness parameter of the pixel unit in the second pixel row.
In this embodiment, the target area where the second pixel row is located may be a non-crosstalk area (outside the crosstalk area) or a crosstalk area (inside the crosstalk area). It should be understood that, the specific determination method for the target area will be described in detail later, and will not be described herein.
In the specific implementation in S530, after determining the target area where the second pixel row is located, the compensation weight value of the pixel unit in the second pixel row may be determined according to the correspondence between the target area and the compensation weight value. The corresponding relation between the target area and the compensation weight value can be specifically set in a targeted manner by integrating the actual display panel performance, the data voltage of the pixel units in the second pixel row, the PVDD jump condition, or other relevant factors, and the application is not limited in strict limitation.
In S540, in a specific implementation, after determining the compensation weight value of the pixel unit in the second pixel row according to the correspondence between the target area and the compensation weight value, the initial compensation value and the compensation weight value obtained in the foregoing steps are combined, and the light-emitting brightness parameters of the M target pixel units in the second pixel row are compensated, so as to obtain compensated light-emitting brightness parameters of the M target pixel units.
The M target pixel units may be all pixel units in the second pixel row, or may be part of pixel units in the second pixel row, which may be determined according to the actual Line cross talk compensation requirement, which is not particularly limited in the present application,
in this embodiment, by introducing the compensation weight value corresponding to the target area where the second pixel Line is located, the second pixel Line in different area positions can be compensated for the difference, so as to improve the Line cross talk compensation effect, thereby effectively and fully improving the problem of uneven display brightness of the display panel and effectively improving the display effect of the display panel.
Referring to fig. 6, fig. 6 is a schematic structural diagram of a target area in a display panel according to an embodiment of the application. As shown in fig. 6, optionally, in order to more reasonably determine the target area where the second pixel row 20 is located, in step 520, determining the target area where the second pixel row is located according to the light emitting brightness parameter of the pixel unit in the second pixel row may specifically include:
and when the difference value of the luminous brightness parameters of any two pixel units in the second pixel row is smaller than a first preset threshold value, determining the target area where the second pixel row is positioned as a non-crosstalk area.
Referring to fig. 6, for example, taking the luminance parameter as a gray scale value, the gray scale value of a portion of the pixel units in the first pixel row 10 is 0, and the gray scale value of a portion of the pixel units is 255. The gray scale value of any two pixel units in the second pixel row 20 is 0. The second pixel Line 20 is a pixel Line in which a Line cross talk (appearing as a dark Line) appears.
The gray scale values of any two pixel units in the second pixel row 20 are all 0, that is, the difference value of the luminance parameters of any two pixel units in the second pixel row 20 is smaller than the first preset threshold value. In this way, the target area where the second pixel Line 20 is located may be determined as the non-Crosstalk area, so that the compensation degree of the Line cross in the second pixel Line 20 can be determined in a targeted manner according to the compensation weight value corresponding to the non-Crosstalk area.
It should be noted that the first preset threshold may be specifically set in combination with Line cross talk related experience, for example, 3 gray levels, 10 gray levels, and the like, which is not specifically limited in the present application.
With continued reference to fig. 6, according to some embodiments of the present application, optionally, for reasons similar to those described in the foregoing embodiments, in order to more reasonably determine the target area where the second pixel row is located, the display panel may include a first display area and a second display area. The first display area may comprise at least a first pixel row 10; at least a second row of pixels 20 may be included in the second display area. In the step 520, determining the target area where the second pixel row is located according to the light emitting brightness parameter of the pixel unit in the second pixel row may further include:
When the target picture is displayed, if the first display area is used for displaying the mixed sub-picture and the second display area is used for displaying the first type sub-picture or the second type sub-picture, determining the target area where the second pixel row 20 is positioned as a non-crosstalk area; the mixed sub-picture may include a first type sub-picture and a second type sub-picture arranged in a row direction.
The difference value between the light-emitting brightness parameter of each pixel unit corresponding to the first sub-picture and the first light-emitting brightness parameter is smaller than a preset difference value threshold, and the difference value between the light-emitting brightness parameter of each pixel unit corresponding to the second sub-picture and the second light-emitting brightness parameter is smaller than a preset difference value threshold.
In particular, for example, referring to fig. 6, the first display area includes a first pixel row 10, and if the first display area is used for displaying the mixed sprite, the area where the first pixel row 10 is located may be determined to be the crosstalk area in fig. 6.
The second display area includes a second pixel row 20, and if the second display area is used for displaying the first type subpicture or the second type subpicture, it may be determined that the target area where the second pixel row 20 is located is a non-crosstalk area, and the second display area may be a display area corresponding to the non-crosstalk area in fig. 6.
The first type of sub-picture may be, for example, a white picture, and the second type of sub-picture may be, for example, a black picture. The mixed sprite may include a first type of sprite and a second type of sprite arranged in a row direction, for example, as represented by the crosstalk zone of fig. 6: white pictures and black pictures arranged in the row direction.
The first luminance parameter may be, for example, 10 gray levels, and the difference between the luminance parameter of each corresponding pixel unit in the first sub-frame and the 10 gray levels of the first luminance parameter is smaller than a preset difference threshold, where the preset difference threshold may be set smaller. Thus, the luminance parameters of any pixel in the first sub-picture are similar to the first luminance parameters.
In combination with the Line cross talk phenomenon, the difference between the first luminance parameter and the second luminance parameter is larger. Based on this, the second light-emitting luminance parameter may be, for example, 200 gray scales, and the light-emitting luminance parameter of any pixel in the second type sub-picture is close to the second light-emitting luminance parameter.
It should be understood that the parameters of the first luminance parameter, the second luminance parameter, the preset difference threshold, and the like are not particularly limited, and specific parameters may be adaptively set in combination with Line cross talk related experience, and the like.

As shown in fig. 7, optionally, according to the light emitting brightness parameter of the pixel units in the second pixel row, determining the target area where the second pixel row is located may include:
and when the difference value of the luminous brightness parameters of the two pixel units in the second pixel row is larger than a second preset threshold value, determining the target area where the second pixel row is positioned as a crosstalk area.
Referring to fig. 7, for example, the gray level of the pixel units in the first pixel row is 0, the gray level of the pixel units in the second pixel row is 0, and the gray level of the pixel units in the second pixel row is 255. The second pixel Line 20 in this case is the Line of pixels in which the Line cross talk (appearing as a bright Line) appears.
In combination with the Line cross talk phenomenon, the second preset threshold is larger, for example, 200 gray levels. When the difference between the luminance parameters (for example, 0 gray scale and 255 gray scale) of the two pixel units in the second pixel row is greater than the second preset threshold, it may be determined that the target area where the second pixel row 20 is located is the crosstalk area. In this way, when compensating the second pixel row 20, the compensation degree of the Line cross in the second pixel row 20 can be determined in a targeted manner in combination with the compensation weight value corresponding to the Crosstalk area.
With continued reference to fig. 7, according to some embodiments of the present application, optionally, for reasons similar to those described in the foregoing embodiments, in order to more reasonably determine the target area where the second pixel row is located, the display panel may include a first display area and a second display area; the first display area may include at least a first pixel row; at least a second pixel row may be included in the second display area; according to the light emitting brightness parameter of the pixel units in the second pixel row, determining the target area where the second pixel row is located may include:
when the target picture is displayed, if the first display area is used for displaying the first type of sub-picture or the second type of sub-picture, and the second display area is used for displaying the mixed sub-picture, determining the target area where the second pixel row is positioned as a crosstalk area; the mixed sub-picture can comprise a first type sub-picture and a second type sub-picture which are arranged in the row direction;
the difference value between the light-emitting brightness parameter of each pixel unit corresponding to the first sub-picture and the first light-emitting brightness parameter is smaller than a preset difference value threshold, and the difference value between the light-emitting brightness parameter of each pixel unit corresponding to the second sub-picture and the second light-emitting brightness parameter is smaller than a preset difference value threshold.
In particular, for example, referring to fig. 7, the first display area includes a first pixel row 10, and if the first display area is used for displaying a first type of sub-picture or a second type of sub-picture, the area where the first pixel row 10 is located may be determined to be the non-crosstalk area in fig. 7.

The first type of sub-picture may be, for example, a white picture, and the second type of sub-picture may be, for example, a black picture. The mixed sprite may include a first type of sprite and a second type of sprite arranged in a row direction, for example, as represented by the crosstalk zone of fig. 7: white pictures and black pictures arranged in the row direction.
The first luminance parameter, the second luminance parameter, the preset difference threshold, and the like are described in the foregoing, and for brevity, the disclosure is not repeated here.
According to some embodiments of the present application, optionally, in order to obtain the initialization offset more reasonably, the obtaining the initialization offset of the pixel unit in the second pixel row may include:
Summing up the luminous brightness parameters of the pixel units in the first pixel row to obtain a first parameter sum;
summing up the luminous brightness parameters of the pixel units in the second pixel row to obtain a second parameter sum;
an initial compensation value for the pixel cells in the second pixel row is determined based on the difference between the first parameter sum and the second parameter sum.
In particular, taking the light-emitting brightness parameter as the data voltage Vdata as an example, after the light-emitting brightness parameters of the pixel units in the first pixel row and the second pixel row are obtained, calculating the sum of the data voltages Vdata of the pixel units corresponding to the first pixel row (the upper Line) to obtain the sum of the first parameters. And calculating the sum of the data voltages Vdata of the pixel units corresponding to the second pixel row (lower Line) to obtain the second parameter sum.
After the first parameter sum and the second parameter sum are calculated, an initial compensation value of the pixel units in the second pixel row is determined according to the difference between the first parameter sum and the second parameter sum.
It should be noted that, a correspondence table between the above-mentioned difference value (upper and lower Line-Vdata difference value) and the initial compensation value may be established in advance, so as to quickly determine the initial compensation value corresponding to the above-mentioned calculated difference value.
For example, referring to fig. 8, fig. 8 is a schematic diagram showing the relationship between the initial compensation value and the upper and lower Line-Vdata difference values according to the embodiment of the present application. In practical application, after obtaining the relationship curve shown in fig. 8, the difference value (the upper and lower Line-Vdata difference value) between the first parameter sum and the second parameter sum can be obtained by calculation, and then the initial compensation value corresponding to the difference value can be obtained by fast query, which is beneficial to improving the Line cross compensation efficiency of the display panel.
The inventor of the present application has found that the observability of the human eyes to the Line cross talk phenomenon is not consistent under different scenes. Due to the human eye's capture capability limitation, even the Line cross talk phenomenon is not easily observed in some scenarios. While in other scenarios, the Line cross talk phenomenon at black and white junctions, for example, is readily observed by the human eye.
Based on this, in order to more purposefully compensate the Line cross phenomenon in the second pixel row to improve the compensation efficiency, according to some embodiments of the present application, optionally, before compensating the light emission luminance parameters of the M target pixel units in the second pixel row based on the initial compensation value and the compensation weight value, the compensation method of the display panel may further include:
M target pixel units are determined based on the light emission luminance parameters of the plurality of pixel units in the first pixel row and the light emission luminance parameters of the plurality of pixel units in the second pixel row.
Referring to the drawings, fig. 9 is a schematic structural diagram of another display panel according to an embodiment of the application. As shown in fig. 9, in some more specific embodiments, to more reasonably determine the M target pixel units in the second pixel row that need to be compensated, the determining the M target pixel units based on the light emitting brightness parameters of the plurality of pixel units in the first pixel row and the light emitting brightness parameters of the plurality of pixel units in the second pixel row may include:
determining a target difference between the light-emitting luminance parameter of the first pixel unit and the light-emitting luminance parameter of the second pixel unit;
if the target difference value is greater than a third preset threshold value, determining the second pixel unit as a pixel unit in M target pixel units;
the first pixel row may include a first pixel unit, where the first pixel unit is any one of a plurality of pixel units in the first pixel row; the second pixel row may include a second pixel unit therein; the second pixel units and the first pixel units are correspondingly arranged in the column direction.
For example, referring to fig. 9, the first pixel unit is located in the first pixel row 10, and the second pixel unit is located in the second pixel row 20. The first pixel units and the second pixel units are correspondingly arranged in the column direction, namely the first pixel units and the second pixel units are positioned in the same column.
In particular, a target difference between the luminance parameter of the first pixel unit and the luminance parameter of the second pixel unit under different columns is first determined. If the target difference value corresponding to a certain column is greater than the third preset threshold value, the Line cross talk phenomenon of the second pixel unit under the column is indicated to be easily observed.
In this case, the second pixel unit under this column is determined as one pixel unit in the second pixel row 20 for which Line cross talk compensation is required, that is, the second pixel unit is determined as a pixel unit among the M target pixel units.
In this embodiment, based on the above-mentioned light-emitting luminance parameters of the plurality of pixel units in the first pixel row and the light-emitting luminance parameters of the plurality of pixel units in the second pixel row, the target pixel unit in the second pixel row, which needs to be subjected to Line cross talk compensation, can be effectively determined, which is favorable for compensating the Line cross talk phenomenon in the second pixel row more pertinently, thereby helping to improve the compensation efficiency of the display panel.
According to some embodiments of the present application, optionally, in order to make the determined compensation weight value more reasonable and comprehensive, determining the compensation weight value of the pixel unit in the second pixel row according to the correspondence between the target area and the compensation weight value may include:
and determining the compensation weight value of the pixel units in the second pixel row according to the corresponding relation between the target area and the compensation weight value and the luminous brightness parameters of the M target pixel units.
In a specific implementation, the magnitude of the compensation weight may be related to specific luminance parameters (e.g., the data voltage Vdata) of the M target pixel units (bright line and dark line regions) in addition to the target region where the second pixel row is located.
It should be understood that, considering that the actual compensation weight setting may also be affected by factors such as panel performance and others, the compensation weight of the pixel units in the second pixel row is not specifically limited in this embodiment.
Referring to fig. 10, fig. 10 is a schematic diagram illustrating a compensation relationship between line crosstalk and initial compensation values and compensation weight values according to an embodiment of the present application.
As shown in fig. 10, optionally, to more effectively compensate the Line cross phenomenon in the second pixel row, the compensating the luminance parameters of the M target pixel units in the second pixel row based on the initial compensation value and the compensation weight value to obtain the compensated luminance parameters of the M target pixel units may include:
Compensating the luminous brightness parameters of the M target pixel units in the second pixel row according to the product of the initial compensation value and the compensation weight value to obtain compensated luminous brightness parameters of the M target pixel units;
after compensating the light emitting luminance parameters of the M target pixel units in the second pixel row, the compensation method of the display panel may further include:
and driving and displaying the M target pixel units according to the compensated luminous brightness parameters of the M target pixel units.
An example is illustrated below in connection with fig. 10. In the related art, the Line cross talk compensation mode is usually the magnitude of the difference value of the data voltages of the upper Line and the lower Line (the first pixel Line and the second pixel Line) to determine the compensation strength, but the influence area of the Line cross talk is in the Crosstalk area or outside the Crosstalk area, which can cause different Line cross talk degrees caused by the difference value of the data voltages of the same upper Line and the lower Line.
Specifically, for example, in fig. 10, position 01 and position 03 are within the crosstalk zone and position 02 and position 04 are within the crosstalk bar in fig. 10. Taking position 01 and position 04 as examples, the difference of the data voltages of the upper and lower lines of position 01 and position 04 is the same, but since the data voltages Vdata at position 01 and position 04 are not uniform and are influenced by other factors, the Line cross talk of position 01 and position 04 have different influence degrees.
Therefore, if the same initial compensation value a is used for both the Line cross talk at the position 01 and the Line cross talk at the position 04, the Line cross talk compensation effect at least one position out of the positions 01 and 04 is poor.
In this embodiment, corresponding position weights (compensation weight values) Gain in and Gain out are set for the positions 01 and 04 in a targeted manner according to whether the influence area of the Line cross talk is in the Crosstalk area (Crosstalk area) or outside the Crosstalk area (non-Crosstalk area), and the final Line cross talk compensation intensities of the positions 01 and 04 are obtained by multiplying the conversion values of the upper Line-Vdata difference values by the position weights.
Specifically, as shown in fig. 10, the Line cross talk at the position 01 is compensated according to the product of the initial compensation value a and the compensation weight value Gain to obtain the compensated light emission luminance parameter at the position 01. And compensating the Line cross talk at the position 04 according to the product of the initial compensation value A and the compensation weight value Gain to obtain the compensated luminous brightness parameter at the position 04.
Thus, the final compensation strength of the Line cross talk is determined together according to the difference value of the upper Line-Vdata and the lower Line-Vdata and the influence area of the Line cross talk, so that the Line cross talk at different area positions can be compensated differently, the Line cross talk compensation effect is improved, the problem of uneven display brightness of the display panel can be effectively and fully improved, and the display effect of the display panel can be effectively improved.
