Abstract: A method for driving display panel and a driving device are disclosed. A transition period is inserted between displaying two neighboring frames, pixels in the nth row to the Nth row of the display panel are switched on simultaneously in the transition period, and a voltage with the highest grayscale is applied to the pixels which are switched on. This is equivalent to turning the grayscale of pixels in the nth row to the Nth row into the highest grayscale after displaying a frame and before displaying a next frame. This can improve the response time of pixels in the nth row to the Nth row during displaying the next frame, and thus can increase the display quality of the display panel.
