Abstract
The embodiments of the present application provide a display panel and a display device. The display panel includes data lines, pixel units, a plurality of gate driving units connected in cascade. At least one gate driving unit includes a pre-charging control module electrically connected with a pre-charging control signal terminal and a scanning signal output terminal of the present stage. The pre-charging control module outputs the pre-charging control signals to the scanning signal output terminal of the present stage, and the data lines output the pre-charging control signals to the corresponding pixel units.
