ABSTRACT:
A display controller has a display data RAM, and generates a frame frequency in an internal oscillating circuit. A memory area of the display data RAM corresponds to a moving image display area of a liquid crystal panel. The liquid crystal panel is driven by moving image data read from the display data RAM at the frame frequency. In the display controller, display data generated at a frame frequency lower than the frame frequency from a display data generation circuit is written to the display data RAM. In this case, a control operation is performed such that the display data is read at the frame frequency after a write operation is performed precedently by at least one scanning line.
