发明名称 In-plane switching type liquid crystal display and method of operating the same
摘要 There is provided an in-plane switching type liquid crystal display including (a) a first transparent substrate, (b) a pixel electrode and a common electrode both formed on an upper surface of the first transparent substrate so that they are spaced away from each other, (c) a second transparent substrate spaced away from the first transparent substrate in parallel, (d) a color filter formed on the second transparent substrate so that the color filter faces the upper surface of the first transparent substrate, (e) a liquid crystal layer sandwiched between the first and second transparent substrates, (f) a pair of polarizing plates sandwiching the first and second transparent substrates therebetween, (g) a back-light source for emitting a back-light through a lower surface of the first transparent substrate, and (h) a chromaticity controller for controlling chromaticity of the back-light in such a manner that chromaticity of the back-light is determined in accordance with chromaticity variation in display nonuniformity caused by a dispersion in a distance between the first and second transparent substrates, to thereby nearly equalize the chromaticity of the back-light to chromaticity in the display nonuniformity for rendering the display nonuniformity inconspicuous. The above-mentioned liquid crystal display reduces display nonuniformity in a display screen.
