The invention aims at the technical problems that in the existing liquid crystal panel adopting the Tri-gate structure, the charging time of pixels is short, and color cast is easily caused by insufficient charging.

As shown in fig. 1, the display panel includes a pixel array 10, a plurality of data line groups 20 arranged along a row direction and spaced apart from each other, and a plurality of scan line groups 30 arranged along a column direction and spaced apart from each other.

Specifically, the pixel array 10 includes a plurality of pixels distributed in an array and spaced apart from each other, and the pixel array 10 may include red pixels (hereinafter, referred to as "R pixels"), green pixels (hereinafter, referred to as "G pixels"), and blue pixels (hereinafter, referred to as "B pixels").

The pixel array 10 includes a plurality of rows of pixel groups 11 and a plurality of columns of pixel groups 12, the rows of pixel groups 11 are arranged at intervals along a column direction, the columns of pixel groups 12 are arranged at intervals along the row direction, that is, each row of pixel groups 11 includes a row of pixels, and each column of pixel groups 12 includes a column of pixels.

As can be seen from fig. 1, the row direction is the horizontal direction, and the column direction is the vertical direction.

Specifically, each of the scan line groups 30 includes at least two scan lines, and each of the scan lines is correspondingly connected to one row of the row pixel groups 11, that is, one scan line is electrically connected to all pixels in one row of the row pixel groups 11, so as to provide a scan signal for the pixels.

It is understood that the number of the scan lines is the same as the number of the row pixel groups 11, and the scan lines are connected in one-to-one correspondence with the row pixel groups 11.

Wherein all the scan lines in each group of the scan line groups 30 are connected to each other.

It should be noted that all the scan lines in each group of scan line groups 30 are electrically connected to each other, when the pixels are charged, all the scan lines in one group of scan line groups 30 are simultaneously turned on or turned off, that is, multiple rows of pixels can be charged simultaneously, and under the condition that the refresh time of each frame is not changed, the charging time of each row of pixels is increased, so that the problem of color shift and other tastes caused by insufficient charging can be prevented.

Specifically, a group of the data line groups 20 is correspondingly connected to a column of the column pixel group 12, that is, a group of the data line groups 20 is electrically connected to all pixels in a column of the column pixel group 12, and the data lines in the data line group 20 provide charging voltages for the pixels in the column pixel group 12.

It is understood that the number of the data line groups 20 is the same as the number of the column pixel groups 12, and the data line groups 20 are connected to the column pixel groups 12 in a one-to-one correspondence.

Specifically, the data line group 20 includes a first data line 21 and a second data line 22 which are spaced apart from each other, the column pixel group 12 includes a plurality of first pixels 121 and a plurality of second pixels 122, the first data line 21 is connected to all the first pixels 121 in the corresponding column pixel group 12, and the second data line 22 is connected to all the second pixels 122 in the corresponding column pixel group 12.

It should be noted that, in each of the column pixel groups 12, the first data line 21 and the second data line 22 are used to charge the first pixel 121 and the second pixel 122, respectively, and the number of pixels connected to each data line is greatly reduced, so that the load on each data line is reduced, and the influence of voltage drop on the charging voltage is reduced.

In one embodiment, each of the data line groups 20 may include only two data lines, and each of the column pixel groups 12 includes only the first pixel 121 and the second pixel 122, where the number of data lines is increased by one time.

Specifically, in each of the column pixel groups 12, the number of the first pixels 121 and the number of the second pixels 122 may be the same, so that the loads of the first data lines 21 and the second pixels 122 are the same, and the charging voltages of all the pixels are more uniform.

Specifically, in each data line group 20, the first data line 21 and the second data line 22 are respectively located at two sides of the corresponding column of pixel groups 12, so that the first data line 21 and the second data line 22 are respectively connected to the first pixel 121 and the second pixel 122.

Specifically, in each row of pixel group 11, all pixels are the first pixels 121 or the second pixels 122, that is, all pixels connected on one scan line are connected to the first data line 21 or the second data line 22, that is, each row of pixels is connected to the same charging voltage, so that the display is more uniform.

Specifically, each of the scan line groups 30 includes a first scan line 31 and a second scan line 32 which are spaced apart from each other, each of the first scan lines 31 is correspondingly connected to a row of the pixel groups 11, each of the second scan lines 32 is correspondingly connected to a row of the pixel groups 11, and the first scan line 31 is electrically connected to the second scan line 32.

It should be noted that the number of the data lines and the number of the scan lines are set, so that the production cost is saved on the premise that the charging time of the pixels can be prolonged.

Specifically, in each of the column pixel groups 12, the first pixels 121 and the second pixels 122 are alternately arranged along the column direction.

It should be noted that the first pixel 121 is powered by the first data line 21, the second pixel 122 is powered by the second data line 22, and the first pixel 121 and the second pixel 122 are alternately arranged, so that the pixels in two adjacent rows can respectively charge the charging voltages provided by the first data line 21 and the second data line 22, thereby enabling the charging to be more uniform.

In one embodiment, the first scan lines 31 and the second scan lines 32 are alternately arranged along the column direction, that is, the first scan lines 31 are adjacent to the second scan lines 32, and all the pixels connected to the first scan lines 31 are one of the first pixels 121 and the second pixels 122, and all the pixels connected to the second scan lines 32 are the other of the first pixels 121 and the second pixels 122.

It should be noted that, if two rows of pixels connected to the first scan line 31 and the second scan line 32 in one scan line group 30 are connected to the same data line, the two rows of pixels are turned on at the same time and charged with the same charging voltage at the same time, and the two rows of pixels can be regarded as one row of pixels, thereby reducing the resolution of the pixel panel.

In the present application, two rows of pixels connected to the first scan line 31 and the second scan line 32 in one scan line group 30 are simultaneously turned on, and the two rows of pixels are charged with the charging voltages provided by the first data line 21 and the second data line 22, respectively, so that the charging time of the pixels can be increased while maintaining the vertical resolution.

As shown in fig. 2, in an embodiment, the display panel further includes a data driver 40 and a scan driver 50, and the data driver 40 is electrically connected to the data lines to supply a charging voltage to the data lines.

In each of the scan line groups 30, the first scan line 31 and the second scan line 32 are electrically connected through a connection line 33, and the connection line 33 is electrically connected to the scan driver 50, so as to reduce the number of gate pad extension lines of the scan driver 50, and further reduce the cost of the display panel.

In one embodiment, in the pixel group 11 of the nth row, all the pixels are R pixels; in the n +1 th row pixel group 11, all the pixels are G pixels; in the pixel group 11 in the n +2 th row, all the pixels are B pixels, and n is a positive integer greater than or equal to 1.

Wherein, the color of all the pixels connected on each data line can be the same or different.

Specifically, the display panel is a liquid crystal display panel, and the display panel may be a display panel with resolution such as ud (ultra High definition) or fhd (full High definition).

The invention has the beneficial effects that: by increasing the number of scan lines and turning on or off all the scan lines in a group of scan line groups 30 at the same time, i.e., multiple rows of pixels can be charged at the same time, the charging time of each row of pixels is increased without changing the refresh time of each frame of the picture, so that the problem of color shift caused by insufficient charging can be prevented, and the scan driver 50 for supplying scan signals is cheaper than the data driver 40 for supplying charging voltage, and the number of data lines is reduced by increasing the number of scan lines, thereby reducing the production cost of the display panel while ensuring the working performance of the display panel.
