LIQUID CRYSTAL DISPLAY DEVICE, DRIVING CIRCUIT AND DRIVING METHOD THEREOF

摘要

A driving circuit for use in a liquid crystal display (LCD) device includes: a drive signal generator for supplying a gate low voltage (VGL) signal, wherein the voltage swing of the VGL signal is substantially zero; a drive signal modifier coupled to the drive signal generator for generating a modified drive signal according to the VGL signal, wherein the voltage swing of the modified drive signal is substantially not zero; and a gate driving circuit coupled to the drive signal modifier for driving a plurality of scan lines of the liquid crystal display device according to the modified drive signal.
