ABSTRACT:
The invention concerns Liquid Crystal Displays (LCD), in which Polymer-Dispersed Liquid Crystal (PDLC) is used. PDLC does not require the use of polarizing filters and half-reflective mirrors, as do some other LCDs. Eliminating the polarizing filters and mirrors eliminates the light attenuation which the filters and mirrors cause. Thus, less light input is required, which increases battery life in devices which are battery-powered. The invention provides a color display by applying color filters to each pixel, and by edge-illuminating the PDLC.
