Abstract:
The invention relates to an apparatus for electronic display comprising means for generating liquid-crystal-display (LCD) input signals, a LCD panel operable to display a color image according to the LCD input signals, a circuit operable to generate a plurality of sets of gamma correction values for gamma correction of the LCD input signals, and means for eliminating dependency of the plurality of sets of gamma correction values on a supply voltage (AVDD) of the circuit.
