| Popis: | — Polymer stabilization is introduced in VA-type LCDs, and fast response time can be achieved along with a high contrast ratio.1 A small amount of reactive monomer is mixed with liquid crystal and forms a polymer layer above the alignment layer by using a UV process. The pre-tilt angle of the liquid crystal is stabilized, and a faster response time can be realized when the bias pre-tilt angle from 90° is increased. The properties of reactive monomers and liquid crystal and the conditions of the UV process were studied. Based on the application of the proper monomer and LC, and an optima UV process, a 65-in. 240-Hz full-HD TFT-LCD, with a faster response time and high contrast ratio, has been developed. |
