Full-color micro LED display for AR glasses

New Products |
By Rich Pell


The Industrial Technology Research Institute (ITRI) has introduced a high resolution full-color micro LED display for AR glasses. The display, says the organization, assists panel manufacturers and other industry players to upgrade their technology, expand their Micro LED applications, meet market demand, and secure business opportunities in next-generation augmented reality (AR) display products for immersive experiences in the metaverse.

The display has 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.

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.

“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,” says Dr. Shih-Chieh Chang, ITRI General Director of 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.”

The display is sold as system-oriented industry integration and fabrication platform services, and is available now.
