ABSTRACT:
Apparatus and methods for harnessing external light to illuminate a display screen of an electronic device are provided. The display screen may be illuminated using a light harness, a reflector, a translucent surface, or any combination thereof. The light harness may be cylindrical or hexahedral. The light harness may be coupled to an external light input or a collector. The reflector may be repositioned toward or away from the display screen to reflect external light toward the display screen. The translucent surface may allow external light to pass through it to illuminate the display screen. The translucent surface may protect the rear face of the display screen, or the rear face of the display screen may itself be translucent.
