Abstract
A transflective Liquid Crystal Display (LCD) system is described, wherein the half silvered mirror is replaced by Chiral Liquid Crystal (CLC) reflectors/filters, which increase the reflected and transmitted brightness from over two times to as much as ten times. These principles are also applied to create an improved efficiency full color transflective LCD and a number of high brightness, limited color, displays.
