Patent ID: 8089437

Claim:
A driver circuit that drives a source line of an electro-optical device based on grayscale data, the driver circuit comprising: a source line driver section that supplies a grayscale voltage corresponding to the grayscale data to the source line; a source output switch section that short-circuits the source line and a common line connected with a capacitor before the source line driver section drives the source line; a charge recycle control section that controls the source output switch section; and a common electrode charge storage switch provided between a first capacitor element connection node connected with one end of a first capacitor element and a common electrode voltage output node to which voltage of the common electrode opposite to the pixel electrode of the electro-optical device through an electro-optical material is supplied, the charge recycle control section determining whether or not to short-circuit the source line and the common line in source output 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-circuiting the source line and the common line based on the determination result of the charge recycle control section, and the common electrode voltage output node and the first capacitor element connection node being electrically connected through the common electrode charge storage switch, and the common electrode being then driven by supplying the common electrode voltage to the common electrode voltage output node.
