ABSTRACT:
The invention provides a device and method for providing backlight to a display in an electronic communication device. The device comprises: a lens to collecting ambient light from outside the device; a body to transmit the ambient light from the lens to a backlight system for the display for dispersion within the backlight system. The backlight system then provides the light as a backlight to the display. A reflector may be provided for the device. An internal shutter may also be provided to block light from escaping out of the lens.
