In order to solve the vertical stripe phenomenon of the display panel during displaying, the inventor has conducted the following research on the display panel provided by the prior art:
referring to fig. 1, fig. 1 is a schematic structural diagram of a display panel according to the prior art. A display panel provided in the prior art is a dual gate line structure, and includes a plurality of gate lines 6, a plurality of data lines 9, and a pixel array 2.
The pixel array 2 includes a plurality of pixel rows 3 and a plurality of pixel columns 4; the pixel row 3 includes a plurality of pixels 5 arranged along a first direction X, and the pixel column 4 includes a plurality of pixels 5 arranged along a second direction Y, where the first direction X and the second direction Y intersect. The gate line group 1 includes two gate lines 6 oppositely disposed, and the gate lines 6 extend along a first direction X; the pixel rows 3 and the gate line groups 1 are arranged in a one-to-one correspondence manner, and in the same pixel row 3, two adjacent pixels are respectively and electrically connected with different gate lines 6 in the same gate line group 1; two gate lines 6 in the gate line group 1 are oppositely disposed on two sides of the corresponding pixel row 3 along the second direction Y. The pixel 5 has a red pixel R, a green pixel G, and a blue pixel B, and the red pixel R, the green pixel G, and the blue pixel B are sequentially arranged repeatedly along the first direction.
The display panel provided by the prior art provides a driving signal to a plurality of gate lines 6 during displaying, so as to provide a data signal to a corresponding pixel 5 through a data line 9. Specifically, fig. 1 illustrates an example in which the number of the gate lines 6 is 10, and the gate lines 6 sequentially receive the driving signals in the following order: gate line 61, gate line 62, gate line 63, gate line 64, gate line 65, gate line 66, gate line 67, gate line 68, gate line 69, and gate line 610. Accordingly, the data lines sequentially transmit data signals to the corresponding pixels 5. The order in which the pixels 5 receive the data signals is shown by the arrows in fig. 1.
In the prior art, in order to save power consumption, the positive polarity and the negative polarity of the same data line 9 in the same frame are kept unchanged. However, when the display panel displays a pure color image, for the same data line 9, the voltage needs to be switched between high and low voltages once (equivalent to displaying a heavy-duty image) during scanning of each row of pixels, which results in larger power consumption of the display panel and reduces the user experience.
For example, when the display panel displays a blue image, referring to fig. 2, the timing diagram of each gate line and data line 91, the data line 91 performs high-low voltage switching once during each row of pixel scanning, which results in large power consumption.
In view of the above, the present invention provides a display panel, a driving method thereof and a display device, so as to improve the problem of large power consumption of the display panel with a dual gate line structure and improve the user experience. The following detailed description is directed to specific embodiments of the invention.

In the second embodiment, at time TA, the scan line GL4 receives the scan signal and controls the driving switch ST of the second subpixel P2 electrically connected thereto to be turned on, the data line DLa transmits the data signal to the corresponding pixel electrode PI through the turned-on driving switch ST, then the scan line GL6 receives the scan signal and controls the driving switch ST of the second subpixel P2 electrically connected thereto to be turned on, the data line DLa transmits the data signal to the corresponding pixel electrode PI through the turned-on driving switch ST, and the data line DLa continuously transmits the data signal to the pixel electrodes PI of the two second subpixels P2, that is, at time TA, the data line DLa maintains a high level signal without switching to a low voltage.
