ABSTRACT:
A backlight system includes at least first and second light-emitting panels (1; 11) having a front wall (2; 12), an opposing rear wall (3; 13) and opposite edge surfaces (4, 14; 5, 15). At least one of the edge surfaces (4; 14) is light-transmitting and associated with a light source (6; 16). Light originating from the light source is diffused in the light-emitting panels and coupled out of the light-emitting panels in the direction of a display device (25), preferably a LCD device. The light source associated with the first light-emitting panel (1) has clusters of red and blue or red and green LEDs. The light source (16) associated with the second light-emitting panel (11) has clusters of blue and green LEDs or only green LEDs.
