Pixelated compensators for twisted nematic liquid crystal displays |
摘要 |
A novel normally-white dual-domain twisted nematic liquid crystal display exhibits dramatically improved contrast and gray scale linearity stability over a wide range of viewing angles as compared to conventional dual-domain twisted nematic displays. The display incorporates one or more pixelated compensator layers internal to the liquid crystal cell. A pixelated compensator layer has a pattern wherein the orientation or retardation of the compensator layer varies according to the tilt domain structure of the display's liquid crystal material. Such a pixelated compensator layer allows optimal compensation for each of the differently oriented liquid crystal tilt domains. The pixelated compensator layer(s), and possibly one or more non-pixelated compensator layers, may be deposited on either a display's active matrix substrate or its (passive) color filter substrate, or a combination thereof.
