A passive-matrix InGaN LED full-color micro-display with 40 × 40 pixels (120 × 40 RGB subpixels) and subpixel pitch of 40 μm × 120 μm was demonstrated. Full-color emission was realized by applying patterned red quantum dot color conversion layer onto a monolithic blue/green dual wavelength LED array.
