Patent ID: 8054408

Claim:
A liquid crystal display comprising: a first backlight source having a backlight spectrum comprising: a first brightness peak wavelength falling into a wavelength range between about 400 nm and about 480 nm; and a second brightness peak wavelength falling into a wavelength range between about 600 nm and about 700 nm; a second backlight source having a backlight spectrum comprising: a third brightness peak wavelength falling into a wavelength range between about 500 nm and about 580 nm; wherein the first backlight source and the second backlight source are coupled to be alternatively driven periodically; and a liquid crystal panel comprising: a liquid crystal layer having a plurality of liquid crystal molecules being controlled for adjusting a transmittance of backlight provided by the first backlight source and the second backlight source; and a color filter for performing color filtering operations on the backlight penetrating through the liquid crystal layer.
