[0002] The present application relates to, but is not limited to, the field of display technology, and specifically to a display panel. Background Art
[0003] Existing display panels generally output multiple clock signals to the gate drive circuit through a level converter electrically connected to the control chip. The gate drive circuit generates voltages to control the on and off of transistors in multiple rows of pixels on the display panel based on the multiple clock signals, thereby controlling the pixels to be turned on row by row, and multiple data lines transmit data signals to each pixel in the pixel row whose gate is turned on.
[0004] Since the gate driving circuit of a traditional display panel needs to turn on the pixels row by row from the first row of pixels to the last row of pixels during one frame until all the pixels of the display panel are charged to display one frame of picture, for a high-resolution display panel with a large number of rows of pixels, the display panel needs to transmit a large amount of data signals during one frame, resulting in higher power consumption of the display panel.
[0005] Therefore, it is necessary to propose a new technical solution to solve the above technical problems. SUMMARY OF THE INVENTION

[0010] a plurality of rows of pixels arranged sequentially along the first direction;
[0011] a gate driving circuit comprising a multi-stage shift register unit, wherein an output end of each stage of the shift register unit is electrically connected to a row of pixels; and
[0012] The selection control circuit includes a frame inversion signal input terminal, a level transmission signal input terminal, a first start signal output terminal, and a second start signal output terminal. The level transmission signal input terminal is electrically connected to the level transmission signal output terminal of the shift register unit electrically connected to the last row of pixels in the second display area, the first start signal output terminal is electrically connected to the input terminal of the shift register unit electrically connected to the first row of pixels in the first display area, and the second start signal output terminal is electrically connected to the input terminal of the shift register unit electrically connected to the first row of pixels in the third display area. The selection control circuit is configured to select one of the first start signal output terminal and the second start signal output terminal to output a start signal during an Nth frame based on the frame inversion signal transmitted by the frame inversion signal input terminal and the level transmission signal transmitted by the level transmission signal input terminal, and to select the other of the first start signal output terminal and the second start signal output terminal to output a start signal during an N+1th frame based on the frame inversion signal input by the frame inversion signal input terminal and the level transmission signal transmitted by the level transmission signal input terminal, wherein N is a non-zero positive integer.

During the (N+1)th frame, the frame inversion signal input terminal FHL transmits a continuous low-level signal. When the last-stage shift register unit Gm1 electrically connected to the pixels of the second display area 102 outputs a level transfer signal to the level transfer signal input terminal Gm1_IN of the selection control circuit 200, the selection control circuit 200 selects the second start signal output terminal STV3 to output a start signal based on the low-level signal transmitted by the frame inversion signal input terminal FHL and the level transfer signal at the level transfer signal input terminal Gm1_IN. The first-stage shift register unit Gm1+m2+1 electrically connected to the pixels in the third display area 103 turns on the gates of the first row of pixels in the third display area 103 based on the start signal output from the second start signal output terminal STV3, and then turns on multiple rows of pixels in the third display area 103 row by row, until all pixels in the third display area 103 have completed one scan, thereby completing the scan of the display panel in the (N+1)th frame.
