Abstract
A display panel includes a driver circuit, multiple scan lines and multiple pixels arranged in an array. Gates of switch transistors in at least part of the same row of pixels are electrically connected to the same one scan line. In the driver circuit, the i-th shift register unit is cascaded with the (i+n)-th shift register unit; shift register units supply gate drive signals to the multiple scan lines respectively. The valid pulses of the gate drive signals each have a width denoted as T; T>(Th+k*Th), 0<k≤(n−1), and Th=1/(F*L), where F denotes the refresh rate of the display panel, and L denotes the number of rows of the multiple pixels; and valid pulses of gate drive signals output by any two adjacent shift register units have a shift amount greater than or equal to Th.
