Abstract
A display device includes a plurality of light emitting diodes (LEDs) having walls that extend through a transparent semiconductor layer and beyond the surface of the transparent semiconductor layer. Each of the walls surrounds at least part of each of the plurality of LEDs to collimate the light emitted by the plurality of LEDs. In some embodiments, the walls collimate the light emitted by the LEDs by reflecting the light or absorbing a portion of the light. The display device may further include an array of optical lenses that faces the surface of the transparent semiconductor layer to further collimate the light emitted from the LEDs.
