Monolithic rgb microled array

A light emitting diode (LED) pixel array comprising:

• a semiconductor wafer template comprising a successively stacked lower n-type gallium nitride (n-GaN) layer, lower multiple quantum well (MQW) layer, lower p-type gallium nitride (p-GaN) layer, upper n-GaN layer, and dielectric layer;
• a plurality of apertures formed through the dielectric layer and extending to the upper n-GaN layer;
• a plurality of mesas formed within the plurality of apertures, each mesa comprising:
• a mesa n-GaN layer;
• a mesa MQW layer above each mesa n-GaN layer;
• and
• a mesa p-GaN layer above each mesa MQW layer,
• such that:
• the mesa n-GaN layer, mesa MQW layer, and mesa p-GaN layer of each mesa form a respective mesa LED;
• and
• the lower n-GaN layer, lower MQW layer, and lower p-GaN layer form a lower LED.
