Abstract
Display devices with improved display contrast and methods of manufacturing the display devices. Some embodiments include a method of manufacturing a light emitting diode (LED) array. The method includes forming a first mesa area of a first LED and a second mesa area of a second LED, where a trench is defined between the first and second mesa areas. At least a portion of the trench is filled with a non-transparent or substantially non-transparent polymeric material that absorbs light emitted from the first and second LEDs.
