Abstract:
A control device includes a data storing unit, a synchronization control unit, and a duty control unit. The synchronization control unit starts a frame period when a vertical synchronization signal is received. The frame period includes a light emission period and a light extinction period. The duty control unit controls a length of the light extinction period, based on a ratio between a total number of vertical lines in a current frame and a pre-set minimum number of vertical lines in a video image displayed on a display panel during a frame period, such that a ratio of a length of the light emission period and a length of the light extinction period during the frame period when a video image is displayed with the total number of vertical lines in the current frame is constant.

Claim (Index 9):
A display device comprising:\n a panel unit in which a plurality of pixel circuits that include light emitting elements are arranged in rows and columns; a source driving circuit that supplies a video image signal to the pixel circuits, the video image signal being a signal that is displayed on the panel unit; a gate driving circuit that supplies a synchronization signal to the pixel circuits, the synchronization signal being a signal for controlling a display timing of the video image signal displayed on the panel unit; and a control device that controls the gate driving circuit and the source driving circuit, the control device including: a data storing unit that temporarily stores the video image signal received from outside; a synchronization control unit that supplies the video image signal from the data storing unit to the panel unit based on a vertical synchronization signal received from the outside or a start timing of the video image signal; and a duty control unit that outputs a light extinction signal for causing the panel unit to extinguish light, and controls light emission and light extinction of the panel unit, wherein the synchronization control unit starts a frame period when the vertical synchronization signal is received, the frame period including: a light emission period during which the panel unit is caused to emit light; and a light extinction period during which the panel unit is caused to extinguish light, the duty control unit controls a length of the light extinction period, based on a ratio between a total number of vertical lines in a current frame and a pre-set minimum number of vertical lines in a video image displayed on the panel unit during the frame period, such that a ratio between a length of the light emission period and a length of the light extinction period during the frame period when a video image is displayed with the total number of vertical lines in the current frame is constant.
