Driving device and driving method for a thin film transistor liquid crystal display

摘要

A driving device and a method of driving a TFT-LCD uses a two-pulse electrode voltage to thereby double the duration of the driving impulse. The driving device includes a liquid crystal interface IC which outputs a two-pulse start signal and a clock signal. A gate bus driver IC outputs a two-pulse gate electrode voltage to each gate line according to the start signal inputted from the liquid crystal interface IC and a liquid crystal pixel is driven by the difference in potential between a grey voltage and a common electrode voltage after the TFT in each gate line is driven by the two-pulse gate electrode voltage input from the gate bus driver IC.
