Abstract:
An object is to realize downsizing and cost reduction of a display device by efficiently using a physical region of a memory in a control circuit of the display device. A structure of a video data storage portion of the control circuit is that provided with a video data storage portion for storing video data of an n-th frame (n is a natural number), a video data storage portion for storing video data of an (n+1)th frame, and a video data storage portion for sharing video data of the n-th frame and the (n+1)th frame among received video data.
