    摘要： A liquid crystal controller for controlling display of a liquid crystal display device of passive matrix type includes gray scale processing being performed on input data before being written in a frame memory for frame frequency conversion and gray scale processing being performed after the frequency conversion and reading of the data from the frame memory so that an amount of information of display data written in the frame memory can be reduced. Further, since the gray scale display pattern is switched by the same switching frequency as the converted frame frequency, pattern movement and flicker of the gray scale display portions can be reduced.
