Full-Color Micro-LED Near-Eye Display Technology Based on Quantum Dot

In the category of near-eye displays used in AR/XR devices, the Micro-LED technology pathway is widely regarded as the ultimate display solution due to its advantages such as high efficiency, brightness, and energy savings. However, at the current stage of development, achieving full colorization of Micro-LEDs is a challenge that the industry generally cannot overcome. Addressing the production bottleneck of Micro-LED micro- displays, we have developed a solution based on Nano-Porous Quantum Dot (NPQD®) technology, which enables direct integration of red, green, and blue colors at the wafer level on low-cost blue LED substrates. Through electro-chemical etching, nanometer-sized pores are etched into gallium nitride material, in which quantum dot materials are then injected. This structure serves as a natural container to help quantum dots perform color conversion, with highlights including high conversion efficiency and reliability. Simultaneously, the team has independently developed a complete set of technologies from epitaxy to module,making it possible to mass-produce new full-color Micro-LED display chips and micro-display modules that are high-efficiency, low-cost, small-sized, and highly reliable.
