The world’s first quantum dot micro-LED chip has started mass production

A screen based on the NPQD® R1 Micro LED chip is going into mass production after a joint test carried out by the group and Saphlux, Inc., in which the group has invested. The first display using a quantum dot Micro LED chip represents a major breakthrough that should accelerate the commercialization of Micro LED display technology.

Micro LED is about to have its moments

NPQD® is a nanopore-based quantum dot chip integration technology. With the unique scattering effect, the nanopores greatly increase the effective optical path, improve the light conversion efficiency, and improve the reliability of quantum dots.

The NPQD® R1 Micro LED chip, developed and put into mass production jointly by the group and Saphlux, overcomes the shortcomings concerning the effect of cold and heat, the classification of the bins, the efficiency, the output and the cost of the traditional chips. Moreover, the chip exploits the wide gamut, stable color and consistency of quantum dots to create a better display effect.

“It’s a monumental breakthrough. The NPQD® Micro LED chip is expected to significantly reduce the size of Micro LED chips, improve display screen performance and reduce production costs. While the Diamond Micro LED series launched on June 30 is expected to capture 80% of the market share of nuclear power plants, the application of quantum dot will help us launch better and more cost-effective products and bring LED display to civilian markets. and domestics. said Li Jun, chairman of the group.

“We really appreciate the support and cooperation of Leyard, which enables mass production and commercial availability of the new technology in such a short time.” Saphlux CEO Dr. Chen Chen said, “The successful combination of Quantum Dot, the optimal color solution available, and Micro LED, the most advanced display technology available, will drive changes in commercial display applications. , AR/VR and others. ”

Quantum dot + Micro LED

Continuous innovation is what constantly drives Leyard forward. With a forward-looking vision, the group made an investment to acquire 12.37% shares of Saphlux in 2017 to jointly develop technologies related to quantum dots and gallium nitride and Micro LED display.

As Saphlux’s second largest outside shareholder, we have worked and interacted closely with the company over the past five years and achieved a major breakthrough in NPQD®Micro LED chip technology. “We will do bulk purchases from Saphlux,” Li added.

As a company specializing in third-generation semiconductor technology, Saphlux is the world leader in semi-polar gallium nitride materials and micro-LEDs based on the development of laboratory research at the University of Yale to industrialization in the last decade.

In addition to the R1 chip, Saphlux has also made significant progress in the color and red color conversion efficiency of the technology roadmap of the T1 series Micro LED display lighting engine for AR/VR and has been recognized by a number of industry leaders. The T1 series Micro LED displays are expected to be released in 2023. With 75 million yuan raised under the B-series in the first half of 2022 and the soon-to-be-closed B+ series, Saphlux has continuously increased its investment in the production of mass of R1 chips and T series product research and development.

Next, the two companies will lead an exploration at the frontiers of AR/VR and help activate the metaverse with software and hardware integrating optical motion capture from Virtual Point under Leyard and the unique NPQD® Micro LED display from Saphlux. .
