Zusammenfassung:A backlight assembly for a gauge of an automotive display panel and a method of illuminating a gauge of an automotive display panel is provided. The backlight assembly includes a lightpipe having a U-shaped configuration and a reflective dish surrounding the lightpipe. The lightpipe and the reflective dish are disposed on a mounting plate of the gauge above a liquid crystal display (LCD). Additionally, the backlight assembly includes one or more top firing light emitting diodes (LEDs) disposed adjacent to the lightpipe. The LEDs emit light to the lightpipe which in turn transmits light to the reflective dish. The reflective dish reflects back or disperses the light evenly to illuminate the graphic applique of the gauge.
