High Resolution Full-Color Micro LED Display for AR Glasses
To drive panel manufacturers and other industry players in meeting demands for immersive AR experiences in the metaverse, ITRI created the High Resolution Full-Color Micro LED Display for AR Glasses. The design adopts heterogeneous integration technology similar to semiconductor processes to create micro-displays with wide color gamut by bringing Micro LED, CMOS, and quantum-dot color conversion layers together within a single panel.
The High Resolution Full-Color Micro LED Display module is suitable for next-generation AR glasses.
This technology is characterized by four key features:
- High resolution (> 2,000 PPI): Its ultra-high resolution is ideal for AR applications.
- High brightness (> 20,000 nits): The Micro LED display provides 10 times higher brightness than the smart glasses currently on the market and can thus work in outdoor scenarios. It meets the brightness requirements of the existing plug-in side-projection AR light machines and can potentially surpass the performance of counterpart displays such as OLED-based designs.
- Great compatibility (< 0.5 inch): The display and sensor functions are integrated in a compact design, which gives the product a slim look.
- Low power consumption (< 1 W): By consuming less than half of the energy of conventional smart glasses, the device can be worn for long hours without recharging.
“ITRI’s High Resolution Full-Color Micro LED Display for AR Glasses has high commercial value and can enhance user experience due to its high resolution, high brightness, device compatibility, compact size, and low power consumption,” said Dr. Shih-Chieh Chang, General Director of ITRI’s Electronic and Optoelectronic System Research Laboratories. “This high resolution Micro LED will help leading global display players to capitalize on the vast range of emerging Micro LED applications. ITRI has assisted manufacturers in pilot production and technology transfers, which have laid the foundation for developing in-vehicle displays and next-gen XR glasses,” he said.

The manufacturing process of this technology transforms the current way of making display modules. Different from conventional LED manufacturing processes, the Micro LED display requires a high-efficiency micrometer-grade LED process and heterogeneous bonding technology with high precision and high resolution on active backplane. The overall process requires semiconductor processes such as high-precision photolithography, CMP planarization, plating, and high-precision alignment wafer bonding. Compared to the class 1000 cleanroom process used by conventional LEDs, it needs a class 10 cleanroom for heterogeneously integrating components.
To introduce ITRI’s Micro LED technology into AR applications and deliver it from lab to market, ITRI founded an alliance in 2016 to integrate the industry chain horizontally. The alliance connects about 50 industry chain suppliers in advanced materials, semiconductor processes, and precision equipment. It provides comprehensive upstream-to-downstream solutions to fulfill industry needs for different stages of verification, development, and IP licensing.
