Abstract
Disclosed is a semiconductor micro-emitter array for use in a full-color microdisplay. Each pixel includes three vertically-stacked red, green, and blue micro-emitters which minimizes pixel size. The microdisplay may be exclusively based on Group III-nitride semiconductors, with differing indium concentrations in three respective InGaN/GaN active regions for emitting the three RGB colors. Alternatively the microdisplay may be based on hybrid integration of InGaN based III-nitride semiconductors for blue and green emissions, and AlGaInP based (e.g., Group III-V) semiconductors for red emissions.
