VOLTAGE REGULATING CIRCUIT

摘要

A voltage regulating circuit. The voltage regulating circuit comprises: a reverse processing module (23) for processing a first initial voltage of a common voltage generation module (21) so as to obtain a reverse voltage of an alternating voltage; an input module (22) for inputting a second initial voltage to a pixel; and an integration module (24) for regulating the first initial voltage according to the reverse voltage of the alternating voltage so that a liquid crystal drive voltage is equal to a pre-set value, wherein the liquid crystal drive voltage is a difference value between the second initial voltage and the regulated first initial voltage.
