Mini/Micro LED Epitaxy and Chip Technology on the Application of Micro Chip Display

This speech focuses on the key role of micro LED epitaxy and chip core technology in micro chip display. Systematically explains epitaxy material system，process difficulties and performance advantage, and combine them with the stringent requirements of AR near eye display to analyze how epitaxy and chips support the key breakthrough of AR to achieve high brightness, low power consumption, ultra-thin and all-weather visibility.

The core technology of micro LED epitaxy includes GaN based blue-green and AlInP/GaInP based heterostructures, multi quantum well design, stress and defect control, and large-scale wafer uniformity control, which are the basis for determining device light efficiency, wavelength consistency, and lifetime; Furthermore, the key process for preparing micro scale chips will be introduced.
