Charge recycling system of liquid crystal display and charge recycling method thereof

Abstract

A charge recycling system of a liquid crystal display includes a controller and at least one switch module. The controller outputs at least one control signal when driving signals of a gate line and a source line of the liquid crystal display are both disabled, and the switch module couples the source line to a voltage supply of a driving circuit of the liquid crystal display according to the control signal. In this way, charges stored in a liquid crystal unit coupled to the source line are recycled to the voltage supply of the driving circuit, therefore raising the utilization efficiency of charges of the liquid crystal display and lowering the power consumed by the liquid crystal display.
