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 17):
A method for driving a display panel including a plurality of pixel circuits that are arranged in rows and columns, the method comprising:\n starting a frame period when a vertical synchronization signal is received or a start timing of a video image signal is detected, the frame period including: a light emission period during which the display panel is caused to emit light; and a light extinction period during which the display panel is caused to extinguish light; initializing the pixel circuits based on reception of the vertical synchronization signal or a start timing of a video image period signal; temporarily storing the video image signal in a data storing unit after the reception of the vertical synchronization signal or the detection of the start timing of the video image period signal; adjusting, by a duty control unit, 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 display panel 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; and displaying the video image signal by causing light emitting elements to extinguish light during the adjusted light extinction period, and causing the light emitting elements to emit light during the light emission period other than the light extinction period in the frame period.
