Abstract:
1. A color liquid-crystal display comprising a plurality of pixels, at least some of the pixels comprising color sub-pixels, the color sub-pixels comprising first sub-pixels, second sub-pixels and third sub-pixels, said liquid-crystal display further comprising: a color filter comprising a red filter segment configured for color filtering in each first sub-pixel, and a blue filter segment configured for color filtering in each third sub-pixel; a liquid crystal layer comprising a plurality of liquid crystal layer segments associated with the color sub-pixels, each liquid crystal layer segment operable in a first state and in a second state; and a backlight source for illuminating the liquid-crystal display through the liquid crystal layer and the color filter, said backlight source comprising a plurality of first light source components and a plurality of second light source components different from the first light source components, such that when the liquid crystal layer segments associated with the first sub-pixels, the second sub-pixels and the third sub-pixels are operated in the first state, the first light source components are turned on for said illuminating; and when the liquid crystal layer segments associated with the second sub-pixels and the third sub-pixels are operated in the first state, and the liquid crystal layer segments associated with the first sub-pixels are operated in the second state, the second light source components are turned on for said illuminating.
