ADDRESSABLE LIGHTING ELEMENT FOR A MOBILE COMMUNICATION DEVICE

摘要

An apparatus that provides lighting for a user interface in a mobile communication device is disclosed. The apparatus may include a planar light guide, at least one light source located adjacent to the planar light guide, a plurality of optical structures having at least a first section of optical structures disposed on the surface of the planar light guide and a second section of optical structures disposed on the surface of the planar light guide separate from the first section of optical structures, wherein the first section of optical structures is configured to cause a first boundary behavior of light associated with the bending of light paths, and the second section of optical structures is configured to cause a second boundary behavior of light associated with the bending of light paths.
