Abstract

A semitransmission-reflection LCD using optical LC film for optical compensation features that a mixed torsional nematic mode is used as its reflection mode and the optical LC film is used for the compensation of transmissive mode. On the basis of existing technology for preparing the reflection-type film transistor, the orientation angle of orientation film is changed to make the included angle between upper and lower substrates be 60-90 deg and the spacer is used to make the gap between them be less than 4 mm to form its LC box in mixed torsional nematic mode. Then, the compensating LC film is stuck on the back of basic glass plate containing the film transistor array and reflecting plate.

Description

technical field [0001] The present invention relates to a transflective reflective active liquid crystal display (AM LCD) using a liquid crystal optical film (LC film) for optical compensation in a transmissive mode, in particular to a hybrid twisted nematic mode (MTN mode ) as reflection mode, and use liquid crystal optical film (LC film) as transmission compensation to solve the problem that transmission and reflection cannot coexist in hybrid twisted nematic mode (MTNN mode) on thin film transistor liquid crystal display (TFT LCD) Transflective Active Liquid Crystal Display (AM LCD). Background technique [0002] The existing transflective thin film transistor liquid crystal display (TFT LCD) has difficulties in choosing the liquid crystal mode. Therefore, so far, among the existing technologies, the better reflection mode is the mixed-mode twisted nematic mode (Mixed-mode TN, proposed by Professor Wu Shicong), but the optical phase of the liquid crystal cell required by...
