A display panel, comprising a gate driving circuit, wherein

the gate driving circuit comprises shift registers of a plurality of stages arranged in sequence, the shift registers of the plurality of stages arranged in sequence are combined into N groups of gate driving sub-circuits, and shift registers in the N groups of gate driving sub-circuits are cascaded, respectively;
an m-th group of gate driving sub-circuits in the N groups of gate driving sub-circuits comprises a shift register of an m-th stage and a shift register of an (m+L*N)-th stage that are cascaded,
wherein m is an integer that is greater than or equal to 1 and less than or equal to N, L is an integer that is greater than or equal to 1, and N is an even number that is greater than or equal to 2.

A driving method for a display panel, wherein the display panel comprises a pixel array and a plurality of gate scanning signal lines, the pixel array comprises a plurality of rows of sub-pixels and a plurality of columns of sub-pixels, and the plurality of gate scanning signal lines are connected to the plurality of rows of sub-pixels, respectively,

the method comprises:
upon the pixel array being driven to display an x-th frame of pattern, gate scanning signal lines of odd-numbered rows in the plurality of gate scanning signal lines outputting gate scanning signals, gate scanning signal lines of even-numbered rows in the plurality of gate scanning signal lines outputting invalid gate scanning signals or not outputting the gate scanning signal;
and
upon the pixel array being driven to display an (x+1)-th frame of pattern, the gate scanning signal lines of the even-numbered rows outputting the gate scanning signals, and the gate scanning signal lines of the odd-numbered rows outputting the invalid gate scanning signals or not outputting the gate scanning signals,
wherein x is an odd number greater than or equal to 1.
