A method for driving a display panel includes controlling a signal of ON/OFF state of a switch in a Demux circuit as a switch signal, and dividing each rising time period in the switch signal into two phases (T, T1), so that the abrupt change effect of voltage generated on both side positions of the display panel and a middle position of the display panel is relatively uniform, ensuring that the charging effect of the display panel at different positions is substantially the same, the brightness of the display panel is even after being driven, and the problem of bright lines in the column direction of the display panel is effectively improved.
