Abstract
A display device and a driving method therefor. The display device includes pixel units and pixel scanning circuits, and each of the pixel scanning circuits corresponds to the pixel units of a row. The driving method for the display device includes: driving, by a first driving signal corresponding to a first scanning frequency, the pixel scanning circuits, the first driving signal having row periods corresponding to a frame of image under the first scanning frequency; obtaining a switching signal, and driving, by a second driving signal corresponding to a second scanning frequency, the pixel scanning circuits according to the switching signal. The second driving signal has row periods corresponding to a frame of image under the second scanning frequency, the first scanning frequency is less than the second scanning frequency, and the row period of the first driving signal is greater than the row period of the second driving signal.
