Abstract:
A display device includes a display panel to display an image, a panel driver to drive the display panel, and a controller to control a driving of the panel driver. The controller includes a first circuit to receive frame data during an active period in synchronization with a vertical synchronization signal determining a start time point of a frame having the active period and a variable blank period, to shift a position of the frame data in response to a shift start signal to generate shift data, and to provide the shift data to the panel driver. A number of active periods of the vertical synchronization signal included in one period of the shift start signal differs from the number of active periods of the vertical synchronization signal included in another period of the shift start signal.
