Abstract:
A liquid crystal display comprising:a liquid crystal panel having a plurality of thin film transistors, a plurality of gate lines connected to gate electrodes of the thin film transistors, a plurality of data lines connected to source electrodes of the thin film transistors; a gate driver that applies a gate signal to the gate lines; a gray voltage generator for generating a gray voltage representing image signal; a data driver that applies to the data lines the gray voltage for displaying an image on the liquid crystal display; a common electrode voltage generator that generates a common electrode voltage applied to the common electrode; and a compensator connected between said liquid crystal display panel and said gray voltage generator, said compensator compensating for the distortion of the common electrode voltage by modifying the gray voltage, wherein said compensator compensates for the distortion of the common electrode voltage by coupling the waveform of the gray voltage to the waveform of the common electrode voltage, and wherein said compensator comprises a capacitor connected between said common electrode and said gray voltage generator.
