[0029] Specifically, the plurality of pixel rows 100 are arranged at intervals in the first direction L, each of the pixel rows 100 includes a plurality of sub-pixels 110 of different colors arranged at intervals along the second direction M, and the arrangement order of the plurality of sub-pixels 110 of different colors in the 2n-th pixel row 100 is different from the arrangement order of the plurality of sub-pixels 110 of different colors in the 2n-1-th pixel row 100; the plurality of data lines 200 are arranged at intervals along the second direction M, and the data lines 200 extend along the first direction L, one data line 200 is connected to two columns of the sub-pixels 110, and each data line 200 is arranged between the two columns of the sub-pixels 110 connected thereto; each A scan line group 300 is arranged between two adjacent pixel rows 100, and each of the scan line groups 300 includes a first scan line 310 and a second scan line 320, the first scan line 310 is adjacent to the second scan line 320, and the first scan line 310 extends along the second direction M, and the second scan line 320 extends along the second direction M; wherein the color of the sub-pixel 110 in the 2n-th pixel row 100 and connected to the k+1-th data line 200 is the same as the color of the sub-pixel 110 in the 2n-1-th pixel row 100 and connected to the k+1-th data line 200, n is a positive integer, and k is a positive integer.

[0030] refer to Figure 1In the related scheme, the sub-pixels in any pixel row 01 of the display panel are periodically arranged in the order of red sub-pixel 11, green sub-pixel 12 and blue sub-pixel 13, and the colors of the sub-pixels in the same pixel column are the same. In the DLG mode of the display panel 10, taking the scanning line G1 and the scanning line G2 being turned on at the same time as an example, there are situations where the red sub-pixel 11 and the green sub-pixel 12 are lit at the same time, the blue sub-pixel 13 and the red sub-pixel 11 are lit at the same time, and the green sub-pixel 12 and the blue sub-pixel 13 are lit at the same time, resulting in mixed colors on the display screen of the display panel 10. Therefore, the technical solution of the present application sets the arrangement order of the multiple sub-pixels 110 of different colors in the 2n-th pixel row 100 to be different from the arrangement order of the multiple sub-pixels 110 of different colors in the 2n-1-th pixel row 100, each of the scan line groups 300 is arranged between two adjacent pixel rows 100, and each of the scan line groups 300 includes a first scan line 310 and a second scan line 320, the first scan line 310 is adjacent to the second scan line 320, and the color of the sub-pixel 110 in the 2n-th pixel row 100 and connected to the k+1-th data line 200 is the same as that in the 2n-1-th pixel row 100. The sub-pixels 110 in the n-1 pixel rows 100 and connected to the k+1th data line 200 have the same color; so that when the first scan line 310 and the second scan line 320 of any scan line group 300 are turned on at the same time, one of the data lines 200 provides a corresponding data voltage to be transmitted to the sub-pixels 110 with the same color, thereby improving the problem of color mixing of the display screen of the display panel 10, and under the DLG driving technology, two sub-pixel 110 rows 100 are driven simultaneously in the same frame period, and the synchronous driving of the dual pixel rows 100 can be achieved without increasing the number of data lines 200.

The color arrangement order of the multiple sub-pixels 110 of the first pixel row 100 is red sub-pixels, green sub-pixels and blue sub-pixels, which are periodically arranged, and the color arrangement order of the multiple sub-pixels 110 of the second pixel row 100 is blue sub-pixels, red sub-pixels and green sub-pixels, which are periodically arranged; in some embodiments, the color arrangement order of the multiple sub-pixels 110 of the first pixel row 100 is green sub-pixels, blue sub-pixels and red sub-pixels, which are periodically arranged, and the color arrangement order of the multiple sub-pixels 110 of the second pixel row 100 is red sub-pixels, green sub-pixels and blue sub-pixels, which are periodically arranged.

The arrangement period of the two-color sub-pixels 110 connected to the 2n-th scan line group 300 is red sub-pixel, green sub-pixel, green sub-pixel, red sub-pixel, green sub-pixel, green sub-pixel... and so on. The two-color sub-pixels 110 connected to the 2n-th scan line group 300 are blue sub-pixel and red sub-pixel, and the arrangement period of the two-color sub-pixels 110 connected to the 2n-1-th scan line group 300 are blue sub-pixel and blue sub-pixel.

[0041] It should be noted that the signal line located in the first pixel row 100 and far away from the first scan line group 300 is not connected to any sub-pixel 110 in the first pixel row 100 .

[0042] In this embodiment, the color of the sub-pixel 110 connected to the k+1th data line 200 and to the 2nth scan line group 300 is different from the color of the sub-pixel 110 connected to the k+1th data line 200 and to the 2n-1th scan line group 300.

[0043] It should be noted that, for the purpose of explanation, k=1 and n=1 is used. When k=1 and n=1, the k+1th data line 200 is the data line 200, and the 2n-1th scan line group 300 is the first scan line group 300, that is, the first scan line group 300 includes the scan line G1 and the scan line G2, and the 2nth scan line group 300 is the second scan line group 300, and the scan lines corresponding to the second scan line group 300 include the scan line G3 and the scan line G4, that is, when the two pixels connected to the first scan line group 300 and the data line 200 are the first sub-pixel 1111, the two pixels connected to the second scan line group 300 and the data line 200 are the third sub-pixel 1113.

By setting two sub-pixels 110 connected to the k+1th data line 200 and to one of the scan line groups 300, one of the sub-pixels 110 is connected to the k+1th data line 200 through a first connecting line 400, and the other sub-pixel 110 is connected to the k+1th data line 200 through a second connecting line 500, and the length of the first connecting line 400 is not equal to the length of the second connecting line 500, so as to ensure that the k+1th connecting line can connect two first sub-pixels 1111, two second sub-pixels 1112 or two third sub-pixels 1113 of two adjacent pixel rows 100.

[0045] It should be noted that, for the purpose of explanation, k=1 and n=1 is used. When k=1 and n=1, the k+1th data line 200 is the data line 200, the 2n-1th scan line group 300 is the first scan line group 300, that is, the first scan line group 300 includes the scan line G1 and the scan line G2, the 2nth scan line group 300 is the second scan line group 300, and the scan lines corresponding to the second scan line group 300 include the scan line G3 and the scan line G4, that is, in the first pixel row 100, the fourth sub-pixel 110 is connected to the scan line G1 and the data line 200 through the first connecting line, and in the second pixel row 100, the second sub-pixel 110 is connected to the scan line G2 and the data line 200 through the second connecting line 500.

[0046] In this embodiment, the length of the first connecting line 400 is greater than the length of the second connecting line 500 .

[0047] In this embodiment, in the same row of pixels, the first connection lines 400 and the second connection lines 500 are alternately arranged.

[0048] In this embodiment, in the same column of pixels, the first connection lines 400 and the second connection lines 500 are alternately arranged.

[0049] In this embodiment, in the first direction L, the sub-pixel 110 includes two types of the first sub-pixel 1111 , the second sub-pixel 1112 , and the third sub-pixel 1113 .

[0050] It should be noted that the reference Figure 3 , in the first direction L, the sub-pixel 110 includes two of the first sub-pixel 1111, the second sub-pixel 1112 and the third sub-pixel 1113; that is, in the first direction L, the sub-pixels 110 of two colors are alternately arranged. The sub-pixel 110 includes two of the first sub-pixel 1111, the second sub-pixel 1112 and the third sub-pixel 1113; it may be that in the first direction L, the sub-pixel 110 includes the first sub-pixel 1111 and the second sub-pixel 1112, or that in the first direction L, the sub-pixel 110 includes the second sub-pixel 1112 and the third sub-pixel 1113, or that in the first direction L, the sub-pixel 110 includes the first sub-pixel 1111 and the third sub-pixel 1113.

[0051] In this embodiment, reference Figure 3, the polarity of the voltage input to the k+1th data line 200 is opposite to the polarity of the voltage input to the k+2th data line 200. Since the polarity of the voltage input to the k+1th data line 200 is set to be opposite to the polarity of the voltage input to the k+2th data line 200, the two adjacent data lines 200 with different polarities of input voltages can be matched with the arrangement of pixels in the column direction, that is, the polarities of the two adjacent sub-pixels 110 in each pixel column are opposite. Compared with the conventional solution in which all the sub-pixels in one pixel column have the same polarity and all the sub-pixels in the other pixel column have the same polarity, and the polarities of the two adjacent columns are opposite, the problem of bright and dark lines in the display screen of the display panel 10 can be improved, thereby improving the display effect of the display screen of the display panel 10.
