Abstract
This disclosure provides systems and methods for illumination systems with one or more reflective structures over a light guide. In one aspect, each reflective structure can have an absorber structure with a width greater than a width of the reflective structure. The absorber structure can have overhanging portions that are in parallel with and laterally protrude past one or more edges of the reflective structure, or the absorber structure can have enclosing portions that substantially enclose the reflective structure. The reflective structures can include light-turning features, such as facets, and/or conductive wires, such as touch sensor wires.
