Abstract
A display device includes a frame frequency conversion circuit configured to convert a frame frequency of an input display data and a timing control circuit configured to control a first drive circuit and a second drive circuit based on a frame frequency after the conversion. The display device generates at least two display areas on the display panel. The at least two display areas display images at different frame frequencies. The display device further includes a switch unit configured to display an image at the frame frequency before the conversion at one of the at least two display areas and configured to display an image at the frame frequency after the conversion at another one of the at least two display areas. At least one of a boundary position and a size of the at least two display areas varies with time.
