Abstract
Disclosed are a flat panel display and a backlight which provides both night vision and day mode backlighting of the flat panel display. The backlight of the flat panel display includes a circuit card and day mode light emitting diodes (LEDs) positioned coplanar with each other on the circuit card. Night vision (NVIS) LEDs are positioned on the circuit card coplanar with the day mode LEDs. An optical wave-guide is positioned in front of the day mode LEDs and the NVIS LEDs and is adapted to distribute light from the day mode LEDs and from the NVIS LEDs forward away from the LEDs and the circuit card.
