Abstract
A liquid crystal display apparatus that controls liquid crystals with a pixel structure having a red pixel, a green pixel, a blue pixel, and a white pixel as a basic unit. Voltage-transmittance characteristics of the liquid crystals corresponding to the white pixel are different from voltage-transmittance characteristics of the liquid crystals corresponding to each of the red pixel, the green pixel, and the blue pixel.
Claims7
A method for controlling liquid crystals with a pixel structure having a red pixel, a green pixel, a blue pixel, and a white pixel as a basic unit, the method comprising:
- differentiating voltage-transmittance characteristics of said liquid crystals corresponding to said white pixel from voltage-transmittance characteristics of said liquid crystals corresponding to each of said red pixel, said green pixel, and said blue pixel;
- and
- adjusting said voltage-transmittance characteristics of said liquid crystals corresponding to said white pixel so that a chromaticity value of a white display formed by said white pixel is matched with a chromaticity value of a white display formed by said red pixel, said blue pixel, and said green pixel.
