Patent ID: 6879310

Claim:
A liquid crystal display comprising: a liquid crystal panel in which pixel electrodes for each of red, green, and blue colors are arranged sequentially and repeatedly on a screen along a scanning line on a same row; a scanning line driving unit to sequentially perform scanning along said scanning line on each row in every scanning period; a reference gray-scale voltage producing unit to produce a reference gray-scale voltage which corresponds to a voltage-transmittance characteristic curve for each of said red, green, and blue colors to be displayed in said liquid crystal panel at every time of scanning along said scanning line for each of said red, green, and blue colors; and a signal line driving unit to make a gamma correction to input gray-scale data corresponding to each color by using said reference gray-scale voltage for each of said red, green, and blue colors and to produce a signal voltage and then to feed said produced signal voltage to a signal line on a column corresponding to said pixel electrode for each of said red, green, and blue colors.
