Abstract
The present invention relates to the field of the backlighting of displays. A backlit display unit comprises a display medium for displaying visible information to a user of the unit, an LED light source for backlighting the display medium, a light diffuser for diffusing light which is incident on the light diffuser, and a printed circuit board carrier which supports the light source. The light diffuser is spaced apart from the display medium and is in an intermediate orientation with respect to the light diffuser and the display medium. The carrier has opposite first and second surfaces, the first surface being oriented generally towards the display medium and the second surface being oriented generally towards the light diffuser. The surfaces are bounded by one or more edges. The arrangement is such that illumination from the light source is directed away from the display medium to be incident upon the light diffuser. This incident light is then diffused by the light diffuser past the edges of the printed circuit board back towards the display medium to provide backlight illumination for the display medium.
