A plurality of sub-pixels are driven to display in a plurality of frames, and each sub-pixel has a high-gray-scale data compensation state or a low-gray-scale data compensation state in each frame and has positive polarity or negative polarity, so that in the same frame, each sub-pixel has a high-gray-scale data compensation state or a low-gray-scale data compensation state or a high-gray-scale data compensation state or a low-gray-scale data compensation state. In a plurality of sub-pixels which have the same display color and have a high-gray-scale data compensation state in any group of adjacent two sub-pixel columns, the polarity of at least one sub-pixel is different from the polarity of other sub-pixels, so that under a Trigate driving architecture, the design of overturning the pixel polarity is realized in each pixel column at an interval of an odd number of sub-pixels, and the polarity of the sub-pixels in the sub-pixel columns is changed. Therefore, the polarity difference among a plurality of sub-pixels which have the same display color of the four adjacent sub-pixel columns and have a high-gray-scale data compensation state is reduced, and the phenomenon that when the head moves, the brightness change generated when the polarity change exists in the corresponding area with the large polarity difference is perceived by human eyes, and the head shaking line phenomenon is generated is improved.

Description

Technical Field

[0001] The present invention relates to the field of display technologies, and particularly to a driving method for a display panel, a driving chip, and a display device. Background Art

[0002] The existing triple gate line - one data line (Triple Gate, Tri - Gate) driving architecture combined with 4Domain VA (4Domain Vertical Alignment) technology can improve the transmittance and save the backlight cost. With the combination of Trigate + 4Domain VA, applying a viewing angle improvement algorithm can meet the requirement of improving the image quality. However, when the Trigate driving architecture is combined with the viewing angle improvement algorithm, due to the conflict between the viewing angle compensation method and the Tri - Gate driving architecture, serious head - shaking patterns will appear on the display screen.

Among them, the plurality of sub-pixel rows include a plurality of first sub-pixel rows, a plurality of second sub-pixel rows, and a plurality of third sub-pixel rows that are alternately arranged. The display colors of the plurality of sub-pixels in the same sub-pixel row are the same, and the display colors of the sub-pixels in the first sub-pixel row, the display colors of the sub-pixels in the second sub-pixel row, and the display colors of the sub-pixels in the third sub-pixel row are all different. The driving method includes: driving the plurality of sub-pixels to display in multiple frames. Among them, each sub-pixel has one of a high gray-scale data compensation state and a low gray-scale data compensation state in each frame, and has one of a positive polarity and a negative polarity. Among them, the display panel includes a plurality of first sub-pixel groups electrically connected to the plurality of first data lines and a plurality of second sub-pixel groups electrically connected to the plurality of second data lines. Each sub-pixel column includes a plurality of first sub-pixel groups and a plurality of second sub-pixel groups that are alternately arranged.

Among them, the polarities of the plurality of sub-pixels in the plurality of first sub-pixel groups are opposite to the polarities of the plurality of sub-pixels in the plurality of second sub-pixel groups.

[0006] In some embodiments, among the plurality of sub-pixels with the same display color and in the high gray-scale data compensation state in the same sub-pixel column, the polarities of two adjacent sub-pixels are opposite.

[0007] In some embodiments, in the same frame, when the sub-pixels with the same display color and in the high gray-scale data compensation state display the same gray scale, the absolute values of the average effective voltages of the adjacent first data line and the second data line are the same.

[0008] In some embodiments, in the same sub-pixel row, the gray-scale data compensation states of two adjacent sub-pixels repeat in opposite and identical orders.

[0009] In some embodiments, in the same sub-pixel column, the gray-scale data compensation states of two adjacent sub-pixels repeat in opposite and identical orders.

[0010] In some embodiments, both the first sub-pixel group and the second sub-pixel group include a first sub-pixel, a second sub-pixel, and a third sub-pixel arranged along the column direction. In the same sub-pixel column, the gray-scale data compensation states of the first sub-pixels of multiple first sub-pixel groups repeat in opposite and identical orders, the gray-scale data compensation states of the second sub-pixels of multiple first sub-pixel groups repeat in opposite and identical orders, and the gray-scale data compensation states of the third sub-pixels of multiple first sub-pixel groups repeat in identical and opposite orders; the gray-scale data compensation state of the first sub-pixel in the second sub-pixel group is opposite to the gray-scale data compensation state of the third sub-pixel of the previous adjacent first sub-pixel group, the gray-scale data compensation states of the second sub-pixels of multiple second sub-pixel groups repeat in opposite and identical orders, and the gray-scale data compensation states of the third sub-pixels of multiple second sub-pixel groups repeat in opposite and identical orders. Among them, the gray-scale data compensation state of the third sub-pixel in each second sub-pixel group is the same as the gray-scale data compensation state of the first sub-pixel of the previous adjacent first sub-pixel group.

[0011] In some embodiments, in the same sub-pixel column, the gray-scale data compensation state of the sub-pixel adjacent to the second sub-pixel in the first sub-pixel group is opposite to the gray-scale data compensation state of the sub-pixel adjacent to the first sub-pixel in the second sub-pixel group; the gray-scale data compensation states of the sub-pixels with the same display color in multiple first sub-pixel groups repeat in opposite orders, and the gray-scale data compensation states of the sub-pixels with the same display color in multiple second sub-pixel groups repeat in opposite orders; the gray-scale data compensation states of two adjacent sub-pixels in each first sub-pixel group are opposite, and the gray-scale data compensation states of two adjacent sub-pixels in each second sub-pixel group are opposite.

[0013] An embodiment of the present invention further provides a display device, including: a display panel and a driving chip electrically connected to the display panel. The driving chip is configured to execute program instructions to implement any one of the driving methods.

[0014] In the driving method, driving chip and display device of the display panel provided by the embodiments of the present invention, by driving multiple sub-pixels to be displayed in multiple frames, and making each sub-pixel have a high gray-scale data compensation state or a low gray-scale data compensation state in each frame, and having a positive polarity or a negative polarity, such that in the same frame, among the sub-pixels with the same display color and a high gray-scale data compensation state in any adjacent two sub-pixel columns, at least one sub-pixel has a different polarity from other sub-pixels. Thus, in the Trigate driving architecture, a design of flipping the pixel polarity is realized by staggering an odd number of sub-pixels in the middle of each pixel column, so as to reduce the polarity difference among the multiple sub-pixels with the same display color and a high gray-scale data compensation state in four adjacent sub-pixel columns, and improve the phenomenon that when the head moves, a brightness change occurs when there is a polarity change in the area with a large polarity difference, which is perceived by the human eye and causes the head shaking pattern.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise stated, the orientation words such as "upper" and "lower" generally refer to the upper and lower in the actual use or working state of the device, specifically the drawing direction in the drawings; and "inner" and "outer" are in terms of the outline of the device.

[0025] As Figure 1 shown, the compensation states of the sub-pixels include a high gray-scale data compensation state H and a low gray-scale data compensation state L, and the polarities of the sub-pixels include a positive polarity + and a negative polarity -. Taking green, which is more sensitive to the human eye, as an example, the problems of moiré and bright-dark lines are described. In two adjacent sub-pixel columns in the first region A1, the green sub-pixel G has a high gray-scale data compensation state H and a negative polarity -. In two adjacent sub-pixel columns in the second region A2, the green sub-pixel G has a high gray-scale data compensation state H and a positive polarity +. Therefore, the polarities of the green sub-pixels G in the first region A1 and the green sub-pixels G in the second region A2 are completely opposite, resulting in a large polarity difference between two adjacent sub-pixel columns in the first region A1 and two adjacent sub-pixel columns in the second region A2.

[0026] Moreover, the green sub-pixels G with a high gray-scale data compensation state H in the first region A1 and the green sub-pixels G with a high gray-scale data compensation state H in the second region A2 will switch polarities within different frames. When the head is stationary, the brightnesses of the first region A1 and the second region A2 are averaged in time and it is not easy for the human eye to perceive uneven brightness. However, once the head moves, the time-averaging effect is destroyed, and then the human eye is likely to perceive uneven brightness, resulting in serious moiré.

[0027] Furthermore, within each frame time, the average effective voltages transmitted by the first data line DL1, the second data line DL2, and the third data line DL3 are all different. As in Figure 2Within a frame as shown, the data voltages transmitted by the first data line DL1 corresponding to multiple sub-pixels are: 0 - 0 - 0 - 0 - 0 - 0 - 0 - 0 - 0 - 0 - 0 - 0 - ……; the data voltages transmitted by the second data line DL2 corresponding to multiple sub-pixels are: 0 - (H - ) - 0 - 0 - 0 - 0 - 0 - (H - ) - 0 - 0 - 0 - 0 - ……; the data voltages transmitted by the third data line DL3 corresponding to multiple sub-pixels are: 0 - (H + ) - 0 - 0 - (H + ) - 0 - 0 - (H + ) - 0 - 0 - (H + ) - 0 - ……. Therefore, within a frame, the average effective voltages Vrms_A transmitted by the first data line DL1, Vrms_B transmitted by the second data line DL2, and Vrms_C transmitted by the third data line DL3 are all different, resulting in the distribution of vertical dark lines in the vertical direction (such as the difference in brightness between GH - in the first region A1 and GH + in the second region A2), causing a serious vertical crosstalk problem.

[0028] Since the bright and dark pixel cycle of the viewing angle improvement algorithm is consistent with the odd flip cycle period in the Trigate driving architecture, the polarity rules of the bright and dark sub-pixels of different colors in the same column are the same, while the polarity rules of the sub-pixels in different regions are different, resulting in the moiré pattern and vertical crosstalk problems (that is, still taking Figure 1 the green sub-pixel G shown as an example, observing Figure 1 the arrangement rule of the green sub-pixels in it, it can be seen that the polarities of the green sub-pixels G with high gray-scale data compensation state H in columns 1, 2, 5, 6, …… are all "-"; the polarities of the green sub-pixels G with high gray-scale data compensation state H in columns 3, 4, 7, 8, …… are all "+", and such an asymmetric polarity arrangement becomes the cause of the moiré pattern and vertical crosstalk).

[0029] Figure 3 FIG. is a schematic plan view of a display device provided by an embodiment of the present invention. An embodiment of the present invention provides a display device 10, and the display device 10 includes a display panel 101 and a driving module 102.

[0030] Optionally, the display panel 101 includes a liquid crystal display panel.

[0031] The display panel 101 includes a plurality of sub-pixels SPX, a plurality of data lines D, a plurality of scan lines SL, and a gate driving circuit GDC.

[0032] The plurality of sub-pixels SPX are used to display an image, the plurality of sub-pixels SPX are arranged in a display area DA, and the plurality of sub-pixels SPX are electrically connected to the plurality of data lines DL and the plurality of scan lines SL. The plurality of sub-pixels SPX are arranged along the intersecting row direction and column direction to form a plurality of sub-pixel rows SPXR arranged in the column direction, and a plurality of sub-pixel columns SPXC arranged in the row direction.

[0033] Optionally, as Figures 3 to 4 shown, a plurality of the sub-pixel rows SPXR include a plurality of first sub-pixel rows SPXR1, a plurality of second sub-pixel rows SPXR2, and a plurality of third sub-pixel rows SPXR3 that are alternately arranged. The display colors of the plurality of sub-pixels SPX in the same sub-pixel row SPXR are the same, and the display colors of the sub-pixels SPX in the first sub-pixel row SPXR1, the display colors of the sub-pixels SPX in the second sub-pixel row SPXR2, and the display colors of the sub-pixels SPX in the third sub-pixel row SPXR3 are all different.

[0034] Optionally, the plurality of sub-pixels SPX include a plurality of first sub-pixels SPX1, a plurality of second sub-pixels SPX2, and a plurality of third sub-pixels SPX3. Each of the first sub-pixel rows SPXR1 includes a plurality of first sub-pixels SPX1, each of the second sub-pixel rows SPXR2 includes a plurality of second sub-pixels SPX2, and each of the third sub-pixel rows SPXR3 includes a plurality of third sub-pixels SPX3. That is, the plurality of sub-pixels SPX form a Trigate driving architecture.

[0035] Optionally, the first sub-pixel SPX1 is a blue sub-pixel, the second sub-pixel SPX2 is a green sub-pixel, and the third sub-pixel SPX3 is a red sub-pixel. In addition, the types of the first sub-pixel SPX1, the second sub-pixel SPX2, and the third sub-pixel SPX3 are not limited thereto.

[0036] The plurality of data lines DL include a plurality of the first data lines DL1 and a plurality of second data lines DL2, and the plurality of first data lines DL1 and the plurality of second data lines DL2 are alternately arranged in the row direction. Among them, the display panel 101 includes a plurality of first sub-pixel groups SPXG1 electrically connected to the plurality of first data lines DL1 and a plurality of second sub-pixel groups SPXG2 electrically connected to the plurality of second data lines DL2. The plurality of first sub-pixel groups SPXG1 and the plurality of second sub-pixel groups SPXG2 included in each sub-pixel column SPXC are alternately arranged so that a second sub-pixel group SPXG2 connected to a second data line DL2 is provided between two adjacent first sub-pixel groups SPXG1 connected to the same first data line DL1. Each of the first sub-pixel groups SPXG1 is electrically connected to a corresponding first data line DL1, and each of the second sub-pixel groups SPXG2 is connected to a second data line DL2.

[0037] Please continue to refer to Figure 3, the gate driving circuit GDC is located within the non-display area NDA. The gate driving circuit GDC drives multiple rows of the sub-pixels SPX through multiple scanning lines SL, so that when multiple rows of the sub-pixels SPX are sequentially turned on row by row, data signals are sequentially loaded into multiple rows of the sub-pixels SPX through multiple data lines DL, thereby enabling the display panel 101 to display a complete frame of image within one frame time. Among them, the non-display area NDA is located on at least one side of the display area DA. Optionally, the non-display area NDA can at least partially surround the display area DA.

[0038] The driving module 102 includes a circuit board 1021 and a chip on film (COF) 1022. Optionally, the circuit board 1021 includes a printed circuit board, and the chip on film 1022 includes a flexible circuit board. The chip on film 1022 includes a source driving chip SIC for transmitting the data signals to multiple data lines DT. The circuit board 1021 includes a timing control chip TCON, and the timing control chip TCON is electrically connected to the source driving chip SIC and the gate driving circuit GDC to output control timing to the source driving chip SIC and the gate driving circuit GDC, so that the source driving chip SIC outputs the data signals according to the control timing, and the gate driving circuit GDC drives multiple rows of the sub-pixels SPX according to the control timing.

[0039] Please continue to refer to Figure 4 , the second sub-pixel group SPXG2 includes 2n + 1 sub-pixels SPX, where n is greater than or equal to 0 and n is a positive integer, so as to achieve the design of flipping the pixel polarity by staggering an odd number of sub-pixels SPX in the middle of each pixel column SPXC.

[0040] Among them, within the same frame, among multiple sub-pixels SPX with the same display color and in the high gray-scale data compensation state H in any two adjacent pixel columns SPXC, the polarity of at least one sub-pixel SPX is different from that of other sub-pixels SPX, so that in any two adjacent pixel columns SPXC, the polarities of multiple sub-pixels SPX with the same display color and in the high gray-scale data compensation state H are not all positive polarity + or negative polarity -, improving the polarity difference among multiple sub-pixels SPX with the same display color and in the high gray-scale data compensation state H in four adjacent pixel columns SPXC. Thus, when the head moves, the brightness change generated when the polarity changes in the area with a relatively large polarity difference can be perceived by the human eye, and the problem of head shaking pattern appears.

[0041] Taking n = 1 as an example, the pixel polarity inversion design of the sub-pixels SPX in each of the sub-pixel columns SPXC will be described.

[0042] Please continue to refer to Figure 4 , within the same frame, the polarities of the sub-pixels SPX in multiple first sub-pixel groups SPXG1 are the same, and the polarities of the sub-pixels SPX in multiple second sub-pixel groups SPXG2 are the same. Among them, the polarities of the sub-pixels SPX in multiple first sub-pixel groups SPXG1 are opposite to the polarities of the sub-pixels SPX in multiple second sub-pixel groups SPXG2, so that the polarities of the sub-pixels SPX in multiple first sub-pixel groups SPXG1 connected to the same first data line DL1 are the same, and the polarities of the sub-pixels SPX in multiple second sub-pixel groups SPXG2 connected to the same second data line DL2 are the same. The polarities of the sub-pixels SPX in multiple first sub-pixel groups SPXG1 connected to the first data line DL1 are opposite to the polarities of the sub-pixels SPX in multiple second sub-pixel groups SPXG2 connected to the adjacent second data line DL2, so as to achieve the design of inverting the pixel polarity by spacing 3 sub-pixels SPX in the middle of each pixel column SPXC. For example, in each pixel column SPXC, a second sub-pixel group SPXG2 including 3 sub-pixels SPX is arranged between two adjacent first sub-pixel groups SPXG1. Within the same frame, the polarities of the sub-pixels SPX in multiple first sub-pixel groups SPXG1 are one of positive polarity and negative polarity, and the polarities of the sub-pixels SPX in multiple second sub-pixel groups SPXG2 are the other of positive polarity and negative polarity. Therefore, in each pixel column SPXC, by spacing 3 sub-pixels SPX, there can be a flip between positive polarity and negative polarity, or a flip between negative polarity and positive polarity.

[0043] Optionally, among the sub-pixels SPX with the same display color and in the high gray-scale data compensation state H in the same sub-pixel column SPXC, the polarities of two adjacent sub-pixels SPX are opposite. For example, among the multiple second sub-pixels SPX2 with the high gray-scale data compensation state H in the first sub-pixel column SPXC1, the polarities of the multiple second sub-pixels SPX2 are negative polarity -, positive polarity + in sequence, so that in a sub-pixel column SPXC, the polarities of the sub-pixels SPX with the same display color and in the high gray-scale data compensation state H are not all positive polarity + or negative polarity -, improving the polarity difference between the sub-pixels SPX with the same display color and in the high gray-scale data compensation state H in two adjacent sub-pixel columns SPXC, thereby improving the phenomenon of head shaking patterns observed by the human eye due to the large polarity difference in the area when the head moves.

[0044] Optionally, in a sub-pixel column SPXC within a frame, the positions where multiple first sub-pixels SPX1 are of negative polarity - are SPX1H- = 12(y1 - 1) + 7, the positions where multiple first sub-pixels SPX1 are of positive polarity + are SPX1H+ = 12(y1 - 1) + 10, the positions where multiple second sub-pixels SPX2 are of negative polarity - are SPX2H- = 12(y1 - 1) + 2, the positions where multiple second sub-pixels SPX2 are of positive polarity + are SPX2H+ = 12(y1 - 1) + 11, the positions where multiple third sub-pixels SPX3 are of negative polarity - are SPX3H- = 12(y1 - 1) + 3, and the positions where multiple third sub-pixels SPX3 are of positive polarity + are SPX3H+ = 12(y1 - 1) + 6. Here, y1 is greater than or equal to 1. That is, in a sub-pixel column SPXC within a frame, the sub-pixel rows SPXR corresponding to the first sub-pixels SPX1 with negative polarity - are: 7, 19, 31,...; the sub-pixel rows SPXR corresponding to the first sub-pixels SPX1 with positive polarity + are: 10, 22, 34,...; the sub-pixel rows SPXR corresponding to the second sub-pixels SPX2 with negative polarity - are: 2, 14, 26,...; the sub-pixel rows SPXR corresponding to the second sub-pixels SPX2 with positive polarity + are: 11, 23, 35,...; the sub-pixel rows SPXR corresponding to the third sub-pixels SPX3 with negative polarity - are: 3, 15, 27,...; the sub-pixel rows SPXR corresponding to the third sub-pixels SPX3 with positive polarity + are: 6, 18, 30,.... Therefore, in the design of flipping the pixel polarity with an interval of 3 sub-pixels SPX in the pixel column SPXC, when the sub-pixel row SPXR is divided by 6 and the remainder is 1, the sub-pixel row SPXR corresponds to the position where the first sub-pixel SPX1 is of negative polarity -. When the sub-pixel row SPXR is divided by 6 and the remainder is 4, the sub-pixel row SPXR corresponds to the position where the first sub-pixel SPX1 is of positive polarity +. When the sub-pixel row SPXR is divided by 6 and the remainder is 2, the sub-pixel row SPXR corresponds to the position where the second sub-pixel SPX2 is of negative polarity -. When the sub-pixel row SPXR is divided by 6 and the remainder is 5, the sub-pixel row SPXR corresponds to the position where the second sub-pixel SPX2 is of positive polarity +. When the sub-pixel row SPXR is divided by 6 and the remainder is 3, the sub-pixel row SPXR corresponds to the position where the third sub-pixel SPX3 is of negative polarity -. When the sub-pixel row SPXR is divided by 6 and the remainder is 0, the sub-pixel row SPXR corresponds to the position where the third sub-pixel SPX3 is of positive polarity +, so as to make the distribution of multiple sub-pixels SPX with high gray-scale data compensation state H in the sub-pixel column SPXC uniform and staggered, thereby reducing the probability of the occurrence of the moiré problem.It can be understood that within another adjacent frame, the positive and negative polarities of multiple said sub-pixels SPX are interchanged.

[0045] As Figure 5 shown, within the same frame, when the sub-pixels SPX with the same display color and in the high gray-scale data compensation state H display the same gray scale, the absolute values of the average effective voltages of the adjacent first data line DL1 and the second data line DL2 are the same. For example, when lighting the second sub-pixel SPX2 in the high gray-scale data compensation state H within the same frame, the voltage of the first data line DL1 can be expressed as: 0-0-0-0-(H-)-0-0-(H-)-0-0-0-0……, and the voltage of the second data line DL2 can be expressed as: 0-(H+)-0-0-0-0-0-(H+)-0-0-0-0……. Therefore, the average effective voltages of the first data line DL1 and the second data line within the same frame are the same in magnitude but opposite in polarity. In this way, the occurrence probability of the vertical crosstalk phenomenon can be effectively reduced.

[0046] Optionally, please continue to refer to Figure 4 , within the same sub-pixel row SPXR, the gray-scale data compensation states of two adjacent said sub-pixels SPX repeat in the order of opposite and the same. For example, among the first six said sub-pixels SPX in the first sub-pixel row SPXR1, the gray-scale data compensation states of the six sub-pixels SPX are in turn the low gray-scale data compensation state L, the high gray-scale data compensation state H, the high gray-scale data compensation state H, the low gray-scale data compensation state L, the low gray-scale data compensation state L, and the high gray-scale data compensation state H.

[0047] Or, please continue to refer to Figures 6 to 7 , among the first six said sub-pixels SPX in the first sub-pixel row SPXR, the gray-scale data compensation states of the six sub-pixels SPX are in turn the high gray-scale data compensation state H, the low gray-scale data compensation state L, the low gray-scale data compensation state L, the high gray-scale data compensation state H, the high gray-scale data compensation state H, and the low gray-scale data compensation state L.

[0048] Please continue to refer to Figure 4 , within the same sub-pixel column SPXC, the gray-scale data compensation states of two adjacent said sub-pixels SPX repeat in the order of opposite and the same. For example, in the first sub-pixel column SPXC1, the gray-scale data compensation states of multiple said sub-pixels SPX are in turn the low gray-scale data compensation state L, the high gray-scale data compensation state H, the high gray-scale data compensation state H, and the low gray-scale data compensation state L.

[0049] Please refer to Figure 6, this embodiment is similar to Embodiment 1, except that: in the same sub-pixel column SPXC, the gray-scale data compensation states of multiple sub-pixels SPX are repeated in the order of high gray-scale data compensation state H, low gray-scale data compensation state L, high gray-scale data compensation state H, low gray-scale data compensation state L, low gray-scale data compensation state L, high gray-scale data compensation state H, low gray-scale data compensation state L, high gray-scale data compensation state H, so that the distribution of multiple sub-pixels SPX with high gray-scale data compensation state H in the sub-pixel column SPXC is evenly staggered, so as to reduce the probability of the occurrence of the moiré problem.

[0050] Specifically, taking the example that both the first sub-pixel group SPXG1 and the second sub-pixel group SPXG2 include a first sub-pixel SPX1, a second sub-pixel SPX2, and a third sub-pixel SPX3 arranged along the column direction for illustration.

[0051] In the same sub-pixel column, the gray-scale data compensation states of the first sub-pixels SPX1 of multiple first sub-pixel groups SPXG1 are repeated in the order of opposite and same, and the gray-scale data compensation states of the second sub-pixels SPX2 of multiple first sub-pixel groups SPXG1 are repeated in the order of opposite and same. In the same sub-pixel column, the gray-scale data compensation states of the third sub-pixels SPX3 of multiple first sub-pixel groups SPXG1 are repeated in the order of same and opposite. The gray-scale data compensation state of the first sub-pixel SPX1 in the second sub-pixel group SPXG2 is opposite to the gray-scale data compensation state of the third sub-pixel SPX3 in the previous adjacent first sub-pixel group SPXG1. The gray-scale data compensation states of the second sub-pixels SPX2 of multiple second sub-pixel groups SPXG2 are repeated in the order of same and opposite, and the gray-scale data compensation states of the third sub-pixels SPX3 of multiple second sub-pixel groups SPXG2 are repeated in the order of opposite and same, where the gray-scale data compensation state of the third sub-pixel SPX3 in each second sub-pixel group SPXG2 is the same as the gray-scale data compensation state of the first sub-pixel SPX1 in the previous adjacent first sub-pixel group SPXG1.

[0052] For example, in the first column of sub-pixel columns SPXC1, the grayscale data compensation states of the first sub-pixels SPX1 in multiple first sub-pixel groups SPXG1 are sequentially the high grayscale data compensation state H, the low grayscale data compensation state L, the low grayscale data compensation state L, the high grayscale data compensation state H, the high grayscale data compensation state H, the low grayscale data compensation state L, the low grayscale data compensation state L, the high grayscale data compensation state H,....

[0056] Correspondingly, in the same sub-pixel column, the gray-scale data compensation state of the sub-pixel SPX adjacent to the second sub-pixel SPX2 in the first sub-pixel group SPXG1 is opposite to the gray-scale data compensation state of the sub-pixel SPX adjacent to the first sub-pixel SPX1 in the second sub-pixel group SPXG2; the gray-scale data compensation states of the sub-pixels SPX with the same display color in multiple first sub-pixel groups SPXG1 are repeated in the opposite order, and the gray-scale data compensation states of the sub-pixels SPX with the same display color in multiple second sub-pixel groups SPXG2 are repeated in the opposite order; the gray-scale data compensation states of two adjacent sub-pixels SPX in each first sub-pixel group SPXG1 are opposite, and the gray-scale data compensation states of two adjacent sub-pixels SPX in each second sub-pixel group SPXG2 are opposite.

[0060] Please refer to Figure 8 , an embodiment of the present invention further provides a driving method for a display panel, which is applied to the display module 1 as described above to drive the display panel 101. The driving method can be implemented by the source driver chip SIC by executing corresponding program instructions. The driving method includes:

[0061] S1 drives multiple sub - pixels SPX to be displayed within multiple frames.

[0062] Wherein, each sub - pixel SPX has a high - gray - scale data compensation state H and a low - gray - scale data compensation state L within the multiple frames, and has a positive polarity + and a negative polarity -.

[0063] Each sub - pixel column SPXC includes multiple sub - pixel groups SPXG. The multiple sub - pixel groups SPXG include a first sub - pixel group SPXG1 electrically connected to a first data line DL1 and a second sub - pixel group SPXG2 electrically connected to a second data line DL2. The multiple first sub - pixel groups SPXG1 and the multiple second sub - pixels SPX2 are alternately arranged in the column direction. The second sub - pixel group SPXG2 includes 2n + 1 sub - pixels SPX, where n is a positive integer, to implement the design of flipping pixel polarities by spacing an odd number of sub - pixels SPX in the middle of each pixel column.

[0064] Optionally, within the same frame, among multiple sub - pixels SPX with the same display color and in the high - gray - scale data compensation state H in any adjacent pair of sub - pixel columns SPXC, the polarity of at least one sub - pixel SPX is different from that of the other sub - pixels SPX, so that in any adjacent pair of sub - pixel columns SPXC, the polarities of multiple sub - pixels SPX with the same display color and in the high - gray - scale data compensation state H are not all positive polarity + or negative polarity -, improving the polarity difference among multiple sub - pixels SPX with the same display color and in the high - gray - scale data compensation state H in four adjacent sub - pixel columns SPXC. Thus, when the head moves, the phenomenon of head - shaking lines observed by the human eye due to a large polarity difference in the region can be improved.

[0065] In addition, every p frames, the polarities of multiple sub - pixels SPX of multiple sub - pixel groups PXG are inverted to achieve polarity symmetry in the time dimension. Wherein, p is a positive integer and p is greater than or equal to 1.

[0066] An embodiment of the present invention further provides a driving chip. The driving chip includes a timing control chip and a source - driving chip connected to the timing control chip. The driving chip is configured to execute program instructions to implement the driving method as described above.
