Abstract
A driving circuit for driving an LCD, using frame modulation, includes: a data converting circuit for frame modulation having at least two averaged patterns for use in averaging brightness during frame modulation and converting display data using the averaged patterns and a display data detecting circuit for detecting the logical states of at least two leading dots specified in said display data. The data converting circuit for frame modulation controls switching of the at least two averaged patterns according to the result of detection. This configuration makes it possible to substantially prevent the occurrence of flickers irrespective of the display pattern. This contributes to realization of an excellent display.
