摘要： A display panel and a display drive method thereof, and a display device are provided. The display panel comprises two parallel and non-overlapping display regions connected to individual scan drive circuits. The display drive method adjusts the pulse width of the light-emitting control signal for each display regions to adjust their respective light-emitting durations within a display period. This method enhances the display quality by avoiding the appearance of a yin-yang screen and improving the display brightness of each display region.
