Abstract
(EN)
A display panel pre-charging method, a display panel and a display device. The display panel pre-charging method comprises: a gate driving circuit outputting a gate start signal; a scan line in the N-th row receiving a gate start signal of the N-th row and charging the pixels in the N-th row. a first trigger switch circuit of a first pre-charging circuit controlling, according to the gate start signal of the Nth row, a first pre-charging switch to be turned on; and the first pre-charging switch synchronously outputting, to a scan line in the N+1th row, the gate start signal of the Nth row received by the scan line in the Nth row, N being a natural number greater than or equal to 1.
