Abstract
Single cell gap transflective liquid crystal display which provides that the backlight traverses the reflective pixel portion twice and thereby follows a path similar to that of the ambient light. A slant reflector is built on the path of the back light to reflect the transmitted light to the reflective portion so that the back light and ambient light follow similar paths.
Claims22
An improved transflective liquid crystal display (LCD) comprising:
- (a) a transmission portion and a reflective portion in the transflective LCD;
- and,
- (b) means on the path of back light in the transmission portion to reflect transmitted light to the reflective portion so that the backlight and ambient light follow similar paths whereby brightness of the reflected and transmissive images are improved.
A method of improving a transflective liquid crystal display comprising the steps of:
- (a) providing a transmission portion and a reflection portion in the transflective LCD;
- and,
- (b) means to reflect the path of back light in said transmission portion to said reflective portion whereby the reflected backlight and ambient light follow similar paths and thereby improve the brightness of the reflected and transmissive images of the transflective LCD are improved.
