INTEGRATED DUAL MODE FLAT BACKLIGHT

摘要

An integrated dual day night backlight (60) includes a flat channel light source (42) with an auxiliary night light source (62) suitably filtered to remove infrared components from the illumination. In alternative embodiments, the night light can be a separate bulb or it can be separate light channels within the flat channel source (80). The night illumination is directed through the edge of the light transmissive face plate that covers the main or day channel. The light directing means can be an inner reflecting surface of the face plate or can be a separate reflective element that redirects the illumination from the night channel through the edge of the transmissive face plate.
