Abstract

This disclosure provides systems, methods and apparatus for a display device with at least one transparent antenna. In one aspect, the transparent antenna is formed on a surface of a transparent substrate and may be electrically reinforced with one or more electrically conductive traces. The transparent antenna can avoid substantial interference with images produced by the display device.
