Abstract
One polarizer reflective-type color liquid crystal display has been developed. Reflective-type liquid crystal display have found increasingly important for both direct-view and projection displays. Attractive features such as high contrast ratio, mirror reflection reduced, and clear image of no parallax are demonstrated. This design uses single polarizer to enhanced the brightness and an inner metallic reflector to avoid parallax.
Claims8
A reflective type liquid crystal display structure comprising:
- a liquid crystal display cell with a first substrate, a second substrate, said first and second substrates being located facing each other with a liquid crystal layer therebetween;
- a tilted reflector being formed on the liquid crystal layer side of said first substrate, said tilted reflector comprising a transparent flatted layer and a plurality of micro-mirrors with a tilted angle of about 2-4 degrees formed in said transparent flatted layer;
- a diffuser located atop said second substrate;
- a retardation film located atop said diffuser;
- and
- a polarizer located atop said retardation film, as an entrance polarizer.
