Abstract
A liquid crystal drive device includes: a shift register circuit for transfer a start pulse signal SP in synchronism with a clock signal CK; an input latch circuit for picking up display data DR, DG, and DB in synchronism with the clock signal CK; and a sampling memory circuit for sampling and storing the display data DR, DG, and DB according to the transferred start pulse signal SP, wherein the input latch circuit is adapted to pick up the display data DR, DG, and DB at both a leading edge and a trailing edge of the clock signal CK. The liquid crystal drive device provides a versatile solution to improvement of the resolution of the liquid crystal display.
