Abstract: A light guide for illuminating a mobile electronic device display. The light guide includes a light source, a light guide panel element having a light input surface located to receive light and a light output surface located proximate to a display active area, and a light guide ring surrounding the light guide panel element and having at least one end located proximate to the light source. The light guide ring may be shaped such that a significant portion of light enters the end(s) of the light guide ring and moves through it around the light guide panel element. A portion of the light moves into the light input surface of the light guide panel element and is redirected out the light output surface toward the display, thereby illuminating it the display with increased efficiency and uniformity. The light guide panel element may be transparent and positioned above or below the display.
