Abstract:
A method of modifying a driving voltage to transparency curve (V-T curve) of a liquid crystal display having a plurality of pixels, each pixel having a liquid crystal component and a transistor, a drain and a gate of the transistor being connected to a data line and a scan line, respectively, a source of the transistor being connected to a first electrode of the liquid crystal component, a second electrode of the liquid crystal component being connected to a common electrode, comprising a step of:applying a modulation voltage waveform to the common electrode to modify the V-T curve of the liquid crystal display, thereby reducing a threshold voltage of a data driver corresponding to the liquid crystal display and increasing the range of operating voltages of the liquid crystal display, wherein the modulation voltage waveform is applied during a front porch period and a back porch period of a driving timing of the liquid crystal display.
