Abstract
A driving method of a display panel obtains a charging time required for each row of sub-pixels in the display panel to reach a target voltage. Then, according to the charging time required for each row of the sub-pixels to reach the target voltage, a duty ratio of a scan drive signal corresponding to each row of the sub-pixels is adjusted. So that, the sub-pixels in each position of the display panel can reach a same target voltage, thereby improving a problem of an uneven brightness of the display panel. And a display panel is also provided.
