摘要： There is provided a liquid crystal display control device which can display pictures in a magnification mode by using only a memory having low-speed access and a low storage capacity. When a video signal has intermediate resolution or less, the enlargement processing is performed by a frame memory, a line memory and an enlargement processing control circuit. If the input operation and the output operation to and from the frame memory are synchronized with each other, it is sufficient for the frame memory to have a storage capacity of two lines. When the video signal has the same high resolution as a liquid crystal display panel, the video signal is output through a gate circuit to a display timing generating circuit, and it is displayed in a through mode. In this case, no processing is performed by the frame memory or the like.

摘要： A display device for displaying display data including a display panel; a driving circuit which generates a gray-scale voltage corresponding to the display data and outputs the gray-scale voltage to the display panel; a scan driver which scans a line on the display panel to which the gray-scale voltage is output; and a control circuit which outputs the display data to the driving circuit and outputs a display control signal to the scan driver. A gray-scale display characteristic of the display data is changeable between a first state in which a difference in a brightness of the display panel between two adjacent display data values becomes smaller as a display data gray-scale increases, and a second state in which the difference in the brightness of the display panel between two adjacent display data values becomes larger as the display data gray-scale increases.
