An active matrix monolithic micro-LED full-colour microdisplay combining GaN-on-Si epilayers and Quantum Dots photoresist (QDs-PR) colour conversion technology. Based on dual wavelength LED structure, a micro-LEDs array can be monolithically fabricated. To realize full-colour LED micro-display, every 3 sub-pixels will be utilized to form a unit with red, green, blue pixels.
The approach of mass transfer is impractical with decreasing yield when subpixel sizes get smaller (<10 μm), seriously hindering its application in near-to-eye displays such like augmented reality (AR) and virtual reality (VR), which may ultimately require subpixels much smaller than 10 μm.
