  • Patent number: 11386829
    Abstract: A display panel and its drive method, and a display device are provided in the present disclosure. The method for driving the display panel includes refreshing a first-color picture N times in one frame. A time interval between every two adjacent refreshings of the N times of the refreshing is T1 for the first-color picture, T1=T2/N, T2 is a duration of the one frame, N>1, and N is a positive integer. The first-color picture may be refreshed multiple times in the one frame, and the multiple refreshing processes of the first-color picture may be evenly distributed, which may reduce each picture retention duration after the first-color picture is refreshed. Furthermore, before the human eyes are not able to recognize the brightness decrease of a previous first-color picture, a next first-color picture is refreshed, thereby effectively improving the picture flickering phenomenon of the display panel.
