【Abstract】GaN-based Micro-LED has become a research hotspot as a novel display technology due to its numerous unique advantages. Especially in augmented reality and smart glasses applications, Micro-LED display chip with high transparency possesses unparalleled opportunities. In this work, GaN-based transparent single-color Micro-LED display chip based on double-side polished sapphire substrate was designed with a singlepixel size of 20 mu m x 20 mu m, and a resolution of 254 pixel per inch (PPI). The transparency reaches 80% among the whole display area similar to 0.18 inch, and the luminance of display chip can reach up to 25000 nits. It demonstratesa broad application prospects in augmented reality, smart glasses, and etc., providing promising vista for the development of "Metaverse" in the future.
