Jingneng Optoelectronics: Three-primary color Micro LED display module will be released this year

Recently, CCTV's "Focus Interview" column broadcast "Strong Alliance to Make Up for Weaknesses and Forge Strengths", focusing on three national innovation centers: the National Graphene Innovation Center, the National Virtual Reality Innovation Center and the National Ultra-HD Video Innovation Center. As one of the founding units of the National Virtual Reality Innovation Center, Jingneng Optoelectronics was interviewed by CCTV.

Jingneng Optoelectronics introduced that the company uses independently innovative GaN-based LED technology on silicon substrates to undertake the development of key common technologies for silicon-based Micro LEDs, providing high-performance Micro LED light source products for virtual reality hardware - AR glasses, and assisting the launch of ultra-small and thin AR glasses.

It is reported that due to its optimism about the application prospects of GaN-based Micro LEDs on silicon substrates in the AR/VR industry, Jingneng Optoelectronics began the research and development of silicon-based Micro LEDs as early as 2018 and has made many breakthroughs.

In 2020, Jingneng Optoelectronics launched 8-inch silicon substrate InGaN red light epitaxy technology, and is still continuing research and development to improve InGaN red light efficiency; in September 2021, Jingneng Optoelectronics successfully prepared a silicon substrate InGaN red, green, and blue three-primary color Micro LED array with a pixel pitch of 25 microns and a pixel density of 1000PPI. At present, the important technical indicator of pixel pitch has been reduced to 8 microns.

It is revealed that Jingneng Optoelectronics’ strip-driven three-color Micro LED display module will be released later this year. With the amplification of Micro LED technology and cost advantages, it is expected to accelerate its large-scale commercial use in large-screen, near-eye display, automotive and other fields.
