Abstract:
A method for driving a flat panel liquid crystal display device, the display device having a plurality of display elements, the display elements being defined by a plurality of scanning electrodes and a plurality of signal electrodes arranged in the form of a matrix with a liquid crystal disposed therebetween, each scanning electrode having a first and second terminal on opposite sides thereof, said driving method comprising:applying a first driving voltage waveform from a first driving circuit to one of the first and second terminals of the scanning electrodes;applying a second voltage waveform to the signal electrodes to drive each display element by producing a voltage difference between the scanning electrode and the signal electrode at the picture elements; andsimultaneously applying the first driving voltage waveform having essentially the same voltage amplitude from a second driving circuit to the other of the first and second terminals associated with at least one scanning electrode.
