Driver circuit, electro-optical device, and electronic instrument
Abstract:
A driver circuit which drives a source line of an electro-optical device includes a source line driver section which supplies a grayscale voltage corresponding to grayscale data to the source line, a source output switch section which short-circuits the source line and a common line connected with a capacitor before the source line driver section drives the source line, and a charge recycle control section which controls the source output switch section. The charge recycle control section determines whether or not to short-circuit the source line and the common line in source line units based on the grayscale data and polarity of a common electrode voltage supplied to a common electrode opposite to a pixel electrode of the electro-optical device. The source output switch section short-circuits the source line and the common line based on the determination result of the charge recycle control section.
