Abstract:
A passive daylight-coupled display having an LCD panel, a diffuser, and a curved reflector behind the LCD panel. For passive backlighting, the diffuser transmits daylight to the reflector, which reflects the daylight to the LCD panel and provides for substantially uniform distribution of the daylight on the LCD panel for backlighting it. A hybrid display includes both a passive backlight and an active backlight for providing backlighting from an active light source.
