ABSTRACT:
In a liquid crystal driver of a liquid crystal display having a structure to switch between image data for partial display from a partial memory and non-display (background pattern), changes in a partial-display area are detected according to a setting command of the partial-display area, and a mask switch is controlled so as to select the background pattern. Timing to write to the last line of the changed partial-display area in the partial memory is determined by an address counter for controlling the partial memory, and the mask switch is controlled so as to select the image data of the partial memory from a next frame.
