It will be understood that the described embodiments are solely some, but not all, embodiments of the present invention. All other embodiments that those skilled in the art can obtain based on the embodiments of the present invention without inventive activity fall within the scope of the present invention. It is to be understood that the embodiments described herein are for the purpose of illustration and explanation of the invention only and are not intended to be a limitation of the invention. In the present invention, unless otherwise stated, directional terms such as "upper" and "lower" are generally used to refer to the upper and lower parts of the device in actual use or working condition, in the direction of the drawing in the accompanying drawings, while the terms "inner" and "outer" refer to the contours of the device.As shown in FIG. 1, the compensation states of the subpixel include a high grayscale data compensation state H and a low grayscale data compensation state L, and the polarities of the subpixel include a positive polarity + and a negative polarity -. Taking the example of green more sensitive to human eyes, the shakehead pattern and dark-light line are illustrated. In two adjacent sub-pixel columns in the first area A1, the green sub-pixel G has a high grayscale data compensation state H and its polarity is a negative polarity. In two adjacent subpixel columns in the second region A 2, the green subpixel G has a high grayscale data compensation state H and its polarity is a positive polarity +. As a result, the polarity of the green subpixel G in the first region A 1 and the polarity of the green subpixel G in the second region A 2 are completely opposite, resulting in a large polarity difference of the two adjacent subpixel columns in the first region A 1 and the two adjacent subpixel columns in the second region A 2.Moreover, the green subpixel G having a high grayscale data compensation state H in the first area A 1 and the green subpixel G having a high grayscale data compensation state H in the second area A 2 change polarity in different frames. When the head is stationary, the brightness of the first area A1 and the second area A2 is averaged over time and less likely to be perceived as non-uniform brightness by human eyes. However, once the head moves and the effect of averaging over time is disturbed, the human eyes can easily perceive the uneven brightness, resulting in the strong shake head pattern.Aul groundm, the average effective voltage transmitted from the first data line DL 1, the second data line DL 2, and the third data line DL 3 is different in time of each frame. As in a frame shown in FIG. 2, the data voltage transmitted from the first data line DL 1 corresponding to the plurality of sub-pixels is: 0-0-0-0-0-0-0-0-0-0-0-...; the data voltage transmitted from the second data line DL 2 corresponding to the plurality of sub-pixels is: 0-(H-)-0-0-0-0-0-0-(H-)-0-0-0-0-...; the data voltage transmitted from the third data line DL 3 corresponding to the plurality of sub-pixels is: 0-(H+)-0-0-(H+)-0-(H+)-0-0-(H+)-0-0-(H+)-0-..... As a result, in one frame, the average effective voltage Vrms_A transmitted from the first data line DL 1, the average effective voltage Vrms_B transmitted from the second data line DL 2, and the average effective voltage Vrms_C transmitted from the third data line DL 3 are different, which results in a vertical dark line distribution in the vertical direction (e.g., there is a brightness difference between the GH- of the first area A 1 and the GH+ of the second area A 2) and a severe vertical crosstalk problem is generated.Since the cycles of the algorithm for improving the viewing angle for light and dark pixels match the odd flip-flop cycle in the trigate drive architecture, the polarity law for light and dark subpixels of different colors in the same column is the same. The different control degrees of the polarities of the subpixel in different areas lead to the problem of the wobble head pattern and the vertical crosstalk (i.e., taking the example of the green subpixel G shown in FIG. 1, considering the arrangement control degrees of the green subpixels in FIG. 1, it can be seen that the green subpixels G in the columns 1, 2, 5, 6, and so on, which have a high grayscale data compensation state H, have a "-" polarity, while the green subpixels G in the columns 3, 4, 7, 8, and so on, which have a high grayscale data compensation state H, have a "+" polarity, which makes the asymmetric polarity arrangement a cause of the wobble head pattern and because vertical crosstalk).FIG. 3 is a schematic view of a planar structure of the display panel provided by the embodiment of the present invention. The embodiment of the present invention provides a display device 10, wherein the display device 10 includes a display panel 101 and a drive chip 102.Optionally, the display panel 101 includes a liquid crystal display panel.The display panel 101 includes a plurality of subpixels SPX, a plurality of data lines D, a plurality of scan lines SL, and a gate drive circuit GDC.A plurality of subpixels SPX are used for displaying an image, the plurality of subpixels SPX are disposed in the display region DA, and the plurality of subpixels 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 crossed row direction and column direction to form the arranged plurality of sub-pixel rows SPX in the column direction and the arranged plurality of sub-pixel columns SPXC in the row direction.Optionally, as shown in FIGS. 3 and 4, the plurality of sub-pixel rows SPXR includes a plurality of first sub-pixel rows SPXR 1, a plurality of second sub-pixel rows SPXR 2, and a plurality of third sub-pixel rows SPXR 3. The plurality of subpixels SPX of a same subpixel row SPXR have the same display color, wherein the display color of the subpixel SPX of the first subpixel row SPXR 1, the display color of the subpixel SPX of the second subpixel row SPXR 2 and the display color of the subpixel SPX of the third subpixel row SPXR 3 are different.Optionally, the plurality of subpixels SPX includes a plurality of first subpixels SPX 1, a plurality of second subpixels SPX 2, and a plurality of third subpixels SPX 3. Each of the first subpixel lines SPXR 1 includes a plurality of first subpixels SPX 1, each of the second subpixel lines SPXR 2 includes a plurality of second subpixels SPX 2, and each of the third subpixel lines SPXR 3 includes a plurality of third subpixels SPX 3, i.e., the plurality of subpixels SPX form a trigate drive architecture.Optionally, the first subpixel SPX 1 is a blue subpixel, the second subpixel SPX 2 is a green subpixel, and the third subpixel SPX 3 is a red subpixel. Moreover, the types of the first subpixel SPX 1, the second subpixel SPX 2, and the third subpixel SPX 3 are not limited thereto.The plurality of data lines DL includes a plurality of the first data lines DL 1 and a plurality of second data lines DL 2, wherein the plurality of first data lines DL 1 and the plurality of second data lines DL 2 are alternately arranged in the row direction. The display panel 101 includes a plurality of first sub-pixel groups SPXG 1 electrically connected to the plurality of first data lines DL 1 and a plurality of second sub-pixel groups SPXG 2 electrically connected to the plurality of second data lines DL 2, wherein the plurality of first sub-pixel groups and the plurality of second sub-pixel groups included in each sub-pixel column are alternately arranged to provide a second sub-pixel group SPXG 2 connected to a second data line DL 2 between two adjacent first sub-pixel groups SPXG 1 connected to the same first data line DL 1. Each of the first sub-pixel group SPXGI 1 is electrically connected to a corresponding first data line DL 1, and each of the second sub-pixel group SPXG 2 is connected to the second data line DL 2.Referring to FIG. 3, the gate driving circuit GDC is located in the non-display area NDA. The gate drive circuit GDC drives a plurality of rows of the subpixels SPX across a plurality of the scan lines SL to load data signals into the plurality of rows of the subpixels SPX sequentially across a plurality of data lines DL when the plurality of rows of the subpixels SPX are turned on line by line, thereby enabling the display panel 101 to display a complete image of images in one frame. The non-display area NDA is located on at least one side of the display area DA. Optionally, the non-display area NDA may at least partially surround the display area DA.The drive module 102 consists of a printed circuit board 1021 and a chip-on-film 1022, wherein the printed circuit board 1021 optionally comprises a printed circuit board and the chip-on-film 1022 comprises a flexible printed circuit board.

The circuit board 1021 includes a timing chip TCON, the timing chip TCON being electrically connected to the source drive chip SIC and the gate drive circuit GDC to output timing to the source drive chip SIC and the gate drive circuit GDC, so that the source drive chip SIC outputs the data signals according to the timing. The gate driving circuit GDC drives a plurality of rows of the sub-pixels SPX according to the timing.Referring to FIG. 4, the second sub-pixel group SPXG 2 includes 2n+1 sub-pixels SPX, where n is greater than or equal to 0 and n is a positive integer, to realize the design of the flip pixel polarity by spacing an odd number of sub-pixels SPX in each pixel column SPXC.In a plurality of subpixels SPX having the same display color and a high grayscale data compensation state in the same frame in an arbitrary group of two adjacent subpixel columns SPXC, the polarity of at least one of the plurality of subpixels is different from the polarity of the other subpixels SPX, so that in the two adjacent subpixel columns SPXC in each group, the plurality of subpixels SPX having the same display color and a high grayscale data compensation state H has a non-positive polarity + or a negative polarity - to improve the polarity difference between the plurality of subpixels SPX having the same display color and a high grayscale data compensation state H in four adjacent subpixel columns SPXC. This improves the phenomenon that, in head movement, a brightness change by human eyes is recognized when there is a polarity change in a range corresponding to a large polarity difference, resulting in a wobble head pattern.The pixel polarity flip design of the subpixel SPX in each of the described subpixel columns SPXC is illustrated using the example of n=1.Referring to FIG. 4, within the same frame, the plurality of subpixels SPX of the plurality of first subpixel groups SPXG 1 have the same polarity and the plurality of subpixels SPX of the plurality of second subpixel groups SPXG 2 have the same polarity, wherein the polarity of the plurality of subpixels SPX of the plurality of first subpixel groups SPXGI 1 is opposite to the polarity of the plurality of subpixels SPX of the plurality of second subpixel groups SPXG 2, such that the plurality of subpixels SPX of the plurality of first subpixel groups SPXG 1 connected to the same first data line DL 1 have the same polarity, the plurality of subpixels SPX of the plurality of second subpixel groups SPXG 2 connected to the same second data line DL 2 have the same polarity, and the plurality of subpixels SPX of the plurality of first subpixel groups SPXG 1 connected to the first data line DL 1 have the same polarity and the same polarity as a plurality of subpixels SPX of a plurality of the second subpixel groups SPXG 2 connected to the adjacent second data line DL 2 to achieve the design of the flip pixel polarity by spacing three subpixels SPX in each pixel column SPXC. For example, in each pixel column SPXC, a second subpixel group SPXG 2 having three subpixels SPX is provided between two adjacent first subpixel groups SPXG 1. Within the same frame, the plurality of subpixels SPX of the plurality of first subpixel group SPXGI 1 has a polarity of positive or negative polarity, and the plurality of subpixels SPX of the plurality of second subpixel group SPXG 2 has a polarity of the other of positive or negative polarity. Thus, in each pixel column SPXC, three spaced-apart subpixels SPX may have a flip between positive and negative polarity or a flip between negative and positive polarity.Optionally, in the plurality of subpixels SPX in the same subpixel column SPXC have the same display color and a high grayscale data compensation state H, two adjacent subpixels SPX having polarities. For example, in the plurality of second subpixels SPX 2, in the first column of subpixel columns SPXC 1 having a high grayscale data compensation state H, the polarity of the plurality of second subpixels SPX 2 is negative polarity -, positive polarity + in this order, so that in the subpixel column SPXC, the plurality of subpixels SPX having the same display color and a high grayscale data compensation state H has a non-positive polarity + or a negative polarity -, thereby improving the polarity difference between two adjacent subpixel columns SPXC of the plurality of subpixels SPX having the same display color and a high grayscale data compensation state H, and thereby improving the phenomenon of the wobble head pattern, This is observed by human eyes due to the large difference in polarity of the region during head movements.Optionally, in one of the columns of sub-pixels SPXC within a frame, the plurality of first sub-pixels SPX1 is negatively polarized - at position SPX1H-=12(y1-1)+7, the plurality of first sub-pixels SPX1 is positively polarized + at position SPX1H+=12(y1-1)+10, the plurality of second sub-pixels SPX2 is negatively polarized - at position SPX2H -=12(y1-1)+2, the plurality of second sub-pixel SPX2 is positively polarized + at position SPX2H+=12(y1-1)+11, the plurality of third sub-pixel SPX3 is negatively polarized - at position SPX3H-=12(y1-1)+3, the plurality of third sub-pixel SPX 3 is positively polarized + at the position SPX 3H+=12(y1-1)+6, where y1 is greater than or equal to 1. The real time, in one of the subpixel columns SPXC within a frame, the first negative polarity subpixel SPX1 corresponds to the subpixel row SPXR of: 7, 19, 31 and so forth, and the first positive polarity subpixel SPX1 corresponds to the subpixel row SPXR of: 10, 22, 34 and so forth, wherein the second negative polarity subpixel SPX2 corresponds to the subpixel row SPXR of: 2, 14, 26 and so forth, wherein the second positive polarity subpixel SPX2 corresponds to the subpixel row SPXR of: 11, 23, 35 and so forth, wherein the third negative polarity subpixel SPX3 corresponds to the subpixel row SPXR of: 3, 15, 27 and so forth, wherein the third positive polarity subpixel SPX3+ corresponds to subpixel row SPXR of: 6, 18, 30, and so on. Therefore, in the design in which the flip pixel polarity is realized with three sub-pixels SPX spaced apart from each other in the pixel column SPXC, the sub-pixel row SPXR corresponds to a position in which the first sub-pixel SPX 1 is negatively polarized - when the sub-pixel row SPXR is divided by 6 and the remainder is 1. When the subpixel row SPXR is divided by 6 with a remainder of 4, the subpixel row SPXR corresponds to a position where the first subpixel SPX 1 has positive polarity +. When the subpixel line SPXR is divided by 6 with a remainder of 2, the subpixel line SPXR corresponds to a position where the second subpixel SPX 2 has negative polarity. When the subpixel row SPXR is divided by 6 with a remainder of 5, the subpixel row SPXR corresponds to a position where the second subpixel SPX 2 has positive polarity +. When the subpixel line SPXR is divided by 6 with a remainder of 3, the subpixel line SPXR corresponds to a position where the third subpixel SPX 3 has negative polarity. When the subpixel row SPXR is divided by 6 with a remainder of 0, the subpixel row SPXR corresponds to a position where the third subpixel SPX 3 has positive polarity +, so that the distribution of the plurality of subpixels SPX in the subpixel column SPXC is equally interlaced with a high grayscale data compensation state H to reduce the likelihood of occurrence of the wobble head pattern. It is to be understood that the positive and negative polarities of the plurality of subpixels SPX are interchanged within another adjacent frame.As shown in FIG. 5, in the same frame, when the subpixels having the same display color and a high grayscale data compensation state display the same grayscale, the absolute value of the average effective voltage of the adjacent first data lines and the second data lines is the same, the absolute value of the average effective voltage of the adjacent first data lines DL 1 and the second data lines DL 2 is the same. For example, when a second subpixel SPX 2 is illuminated in the high grayscale data compensation state H within the same image, the voltage of the first data line DL 1 may be expressed as 0-0-0-0-(H-)-0-0-(H-)-0-0-0-0...., and the voltage of the second data line DL 2 may be expressed as 0-(H+)-0-0-0-0-0-0-(H+)-0-0-0-0..... Thus, the first data line DL 1 and the second data line have the same average effective voltage magnitude and opposite polarities within the same frame. In this way, the probability of vertical crosstalk can be effectively reduced.Optionally, referring to FIG. 4, the grayscale data compensation states of two adjacent subpixels SPX in the same subpixel row SPXR are repeated in the reverse order or in the same order. For example, in the first six sub-pixels SPX of the first row of sub-pixel rows SPXR 1, the grayscale data compensation states of the six sub-pixels SPX are sequentially a low grayscale data compensation state L, a high grayscale data compensation state H, a high grayscale data compensation state H, a low grayscale data compensation state L, a low grayscale data compensation state L, a high grayscale data compensation state H.Or referring to FIGS. 6-7, in the first six sub-pixels SPX of the first row of sub-pixel rows SPXR, the grayscale data compensation states of the six sub-pixels SPX are sequentially a high grayscale data compensation state H, a low grayscale data compensation state L, a low grayscale data compensation state L, a high grayscale data compensation state H, a high grayscale data compensation state H, a low grayscale data compensation state L.Referring to FIG. 4, the grayscale data compensation states of two adjacent subpixels SPX in the same subpixel column SPXC are repeated in the reverse order or in the same order. For example, in the first column of subpixel columns SPXC 1, the grayscale data compensation states of the plurality of subpixels SPX are sequentially a low grayscale data compensation state L, a high grayscale data compensation state H, a high grayscale data compensation state H, a low grayscale data compensation state L.Referring to FIG. 6, this embodiment is similar to Embodiment 1, except that: in the same subpixel column SPXC, the grayscale data compensation states of the plurality of subpixels SPX are repeated in order of a high grayscale data compensation state H, a low grayscale data compensation state L, a high grayscale data compensation state H, a low grayscale data compensation state L, a low grayscale data compensation state L, a high grayscale data compensation state H, a low grayscale data compensation state L, a high grayscale data compensation state H, so that the distribution of the plurality of subpixels SPX in the subpixel column SPXC is equally interleaved with a high grayscale data compensation state H to reduce the probability of occurrence of the wobble head pattern.Specifically, it is illustrated by the example that the first sub-pixel groups SPXG 1 and the second sub-pixel groups SPXG 2 both include a first sub-pixel SPX 1, a second sub-pixel SPX 2, and a third sub-pixel SPX 3 arranged along the column direction.In the same subpixel column, the grayscale data compensation state of the first subpixel SPX 1 of the plurality of first subpixel groups SPXG 1 is repeated in the reverse order or in the same order, the grayscale data compensation state of the second subpixel SPX 2 of the plurality of second subpixel groups SPXG 1 is repeated in the reverse order or in the same order. In the same subpixel column, the grayscale data compensation state of the third subpixel SPX 3 of the plurality of first subpixel groups SPXG 1 is repeated in the reverse order or in the same order. The grayscale data compensation state of the first subpixel SPX 1 of the second subpixel group SPXG 2 is opposite to the grayscale data compensation state of the third subpixel SPX 3 of the previous adjacent first subpixel group SPXG 1, wherein the grayscale data compensation state of the second subpixel SPX 2 of the plurality of second subpixel groups SPXG 2 is repeated in the reverse order or in the same order, the grayscale data compensation state of the third subpixel SPX 3 of the plurality of second subpixel groups SPXG 2 is repeated in the reverse order or in the same order, wherein the grayscale data compensation state of the third subpixel SPX 3 in each of the second subpixel group SPXG 2 is the same as the grayscale data compensation state of the first subpixel SPX 1 of the preceding adjacent first subpixel group SPXG 1.For example, in the first column of subpixel columns SPXC 1, the grayscale data compensation states of the first subpixel SP 1 of the plurality of first subpixel groups SPXG 1 are sequentially a high grayscale data compensation state H, a low grayscale data compensation state L, a low grayscale data compensation state L, a high grayscale data compensation state L, a high grayscale data compensation state H, a low grayscale data compensation state L, a low grayscale data compensation state L, a high grayscale data compensation state L, and so forth. In the first column of sub-pixel columns SPXC 1, the grayscale data compensation states of the second sub-pixel SP 2 of the plurality of first sub-pixel groups SPXG 1 are sequentially a low grayscale data compensation state L, a high grayscale data compensation state L, a high grayscale data compensation state H, a low grayscale data compensation state L, a low grayscale data compensation state L, a high grayscale data compensation state L, a high grayscale data compensation state H, a low grayscale data compensation state L, and so forth. In the first column of subpixel columns SPXC 1, the grayscale data compensation states of the third subpixel SP 3 of the plurality of first subpixel groups SPXGI 1 are sequentially a high grayscale data compensation state L, a high grayscale data compensation state H, a low grayscale data compensation state L, a low grayscale data compensation state L, a high grayscale data compensation state L, a high grayscale data compensation state H, a low grayscale data compensation state L, a low grayscale data compensation state L, and so forth.
