Modification of the V-T curve of an LCD by changing the waveform of common voltage

摘要

A method of modifying a driving voltage to the transparency curve (V-T curve) of a liquid crystal display having a plurality of pixels having a transistor and a liquid crystal capacitor connected to a common electrode. Applying a voltage waveform to the common electrode, during the front/back porch periods of a driving timing of the liquid crystal display, modifies the driving voltage to the transparency curve of the liquid crystal display.
