Abstract:
A micro display, which includes LEDs and TFTs of a TFT electronic control circuit for controlling the LEDs, is produced monolithically on a silicon, silicon carbide, or sapphire wafer. The display includes red, green, and blue micro LEDs, and electronic control circuits include TFTs with Indium gallium zinc oxide (IGZO) channels or Indium phosphide (InP) channels. The TFTs are formed above the LEDs and laterally removed from the LEDs and paths of light emissions from the plurality of LEDs to prevent light blocking by the TFTs.
