发明名称 Liquid crystal display device and method for decaying residual image thereof
摘要 By way of enabling a reset signal while turning off a liquid crystal display, a method for decaying residual image of the liquid crystal display is capable of setting the corresponding gate signal of each of a plurality of gate lines of the liquid crystal display based on the reset signal being enabled. Accordingly, enhanced discharging processes on all the storage units of the liquid crystal display for fast decaying residual image can be performed via the data switches of the liquid crystal display turned on by the gate signals being set. The reset operation for performing discharging processes in response to the reset signal can be carried out based on a reset circuit for setting all the gate signals to become high-level signals, or based on a charging/discharging module for furnishing a high-level voltage directly to all the gate lines.

主权项 1. A method for driving a liquid crystal display device comprising: enabling a reset signal upon turning off the liquid crystal display device; setting a gate signal of each gate line of a plurality of gate lines of the liquid crystal display device based on the reset signal being enabled; providing a first clock signal, a second clock signal, and a gate signal reference voltage with a high voltage level to a gate driving circuit generating the gate signal of each gate line such that the gate signal of each gate line is switched to the high voltage level in response to the gate driving circuit receiving the first clock signal, the second clock signal, and the gate signal reference voltage with the high voltage level, the first clock signal and the second clock signal being oscillating signals that alternate between a high and a low state during each clock period when the reset signal is disabled, the first clock signal and the second clock signal having substantially the same clock period and being out of phase with one another; providing the reset signal being enabled upon turning off the liquid crystal display device to a reset circuit which receives a first clock logic signal, a second clock logic signal and the reset signal being enabled; forwarding a first high-level logic output signal, a second high-level logic output signal, and a third high-level logic output signal from the reset circuit to a power circuit in response to enabling the reset signal; forwarding the first clock logic signal, the second clock logic signal and a low-level logic signal from the reset circuit to the power circuit before enabling the reset signal; providing the first clock signal, the second clock signal, and the gate signal reference voltage with the high voltage level from the power circuit to the gate driving circuit in response to receiving the first high-level logic output signal, the second high-level logic output signal, and the third high-level logic output signal; turning on each data switch of a plurality of data switches of the liquid crystal display device based on one corresponding gate signal being set; and performing a discharging process on each storage unit of a plurality of storage units of the liquid crystal display device based on one corresponding data switch being turned on.
