Patent ID: 8188952

Claim:
A method of reducing flicker in a liquid crystal display (LCD), wherein the LCD produces a display based on a video signal, the method comprising: determining a gamma curve of the LCD for producing a predetermined luminance performance, wherein the gamma curve comprises a plurality of gamma reference voltages corresponding to a plurality of gray scale values of the video signal; driving the LCD by a first test pattern comprising a first gray scale value of the plurality of gray scale values; measuring a first flicker of the LCD driven by the first test pattern; adjusting a first gamma reference voltage in the gamma curve based on the first flicker, wherein the first gamma reference voltage corresponds to the first gray scale value; driving the LCD by a second test pattern comprising a second gray scale value of the plurality of gray scale values; measuring a second flicker of the LCD driven by the second test pattern; and adjusting a second gamma reference voltage in the gamma curve based on the second flicker, wherein the second gamma reference voltage corresponds to the second gray scale value.
