Abstract
Disclosed is a display of a particular size that may be perceived as larger than the particular size as a result of light emitted by one or more light guides adjacent the perimeter of the display. The display may also be perceived as brighter. In particular, the display is configured to output a changing image. A light guide is disposed adjacent at least a portion of the perimeter of the display and coupled to a multicolor LED. A controller of the electronic device is configured to analyze the changing image to determine the color content. The multicolor LED is driven to emit light according to the color content of the changing image. The light guide is configured to couple light from the LED in a direction parallel to the display viewing surface, and to couple light out of the light guide in a direction away from the display viewing surface.
