description An electronic device is disclosed that redirects light escaping from a display assembly light source to an illuminable region of the electronic device. In some embodiments, the electronic device includes a light guide panel arranged along a rear surface of the display assembly and configured to receive light escaping from a lateral side of the light source. The light guide panel can then be arranged to transport that light to a position behind the illuminable region and emit it back out in a focused beam having a size about the same as the illuminable region. In some embodiments the illuminable region can be a logo or device identifier.
