Driving Device for Quickly Changing the Gray Level of the Liquid Crystal Display and Its Driving Method

摘要

A driving device for quickly changing the gray level of the liquid crystal display and its driving method are disclosed. The driving device includes a group of thin film transistors with matrix array, a plurality of gate lines and a plurality of data lines. The object of quickly changing the gray level of the liquid crystal display can be accomplished by the different arrangement of the gate lines and the data lines and the different connection of the thin film transistors with the gate lines and the data lines. The driving method for the said driving device includes: two gate lines in the liquid crystal display are simultaneously or synchronously turned on according to in the bright period or in the black period, the voltage for displaying the present frame interval data or the voltage for displaying black image is given to the thin film transistors connected with the gate lines, and scanning continues in turn. The present invention suits for the picture treatment of various liquid crystal displays, organic light emitting diode (OLED) display or plasma display panel (PDP).
