Title: Drive method for active matrix type liquid crystal display device
Inventor: SUJUKI YOUSIOH
IPC: G02F1/133
Filed: 1993-06-16
Granted: 2001-09-17
Abstract: PURPOSE: To restrain the voltage shift of an image signal inputted to a liquid crystal picture element by shaping the waveform of a gate pulse. CONSTITUTION: An active matrix type liquid crystal display device comprises liquid crystal elements arrayed in a matrix and picture element transistors to drive respective elements. In this case, a gate pulse GP is applied to the gate electrodes of the picture element transistors during a selection period, thereby writing an image signal Vsig in each element. Subsequently, the application of the gate pulse GP is interrupted during a non-selection period and the written image signal Vsig is held. In transition from the selection period to the non-selection period, the gate pulse GP is caused to smoothly rise, thereby restraining the voltage shift ΔV of the written signal Vsig. Instead, the voltage level Vgate 1 of the gate pulse GP is once lowered to Vgate 2 immediately before transition from the selection period to the non-selection period and, then, further lowered, thereby restraining the voltage shift ΔV of the written image signal Vsig.
