Focusing on breaking through the AR problem, Guangfeng Technology announced the world's first PPI-breaking AR optical module

Songguo Finance learned that on May 7, Guangfeng Technology held a media exchange meeting in Shenzhen and announced the world's first PPI-breaking AR optical module developed by itself. This marks a major breakthrough in the technology research and development of Guangfeng Technology in the field of AR.

According to the person in charge of AR technology of Guangfeng Technology, the self-developed AR optical module focuses on making breakthroughs in the underlying technical architecture, making significant progress at the level of high pixel density, and becoming the world's first PPI-breaking AR optical commercial module. This pocket-sized AR optical module is suitable for AR eyewear end products and will be suitable for a wider range of use scenarios in the future.

Announced the world's first PPI exceeding 10,000, commercial AR optical modules

Guangfeng Technology AR R & D team realized that achieving higher resolution in the same size, that is, achieving higher PPI on display devices, will become an important technical direction for AR display in the future. Therefore, based on the innovation of optics, structure, algorithms and other multi-technology fields, spD (super pixel density) technology has been developed, and within a volume of 0.5cc (cubic centimeters), it has achieved more than 10,000 PPI, 720p resolution, 40 degree field of view angle and power consumption below 200mW, under the same volume, the image clarity is more than twice the industry average, and it has also become the world's first commercial AR optical module to exceed 10,000 PPI.

In addition, the full-scene AR optical module announced this time can solve the industry's pain points of lightweight adaptation to daily wear, and meet the brightness needs required for indoor and outdoor multi-applicable scenes. The R & D team uses a diffractive waveguide as an optical combiner scheme to achieve a transmittance of more than 85%, so that the lens is thin enough to achieve lightweight demand; at the same time, it greatly improves the display brightness of the entire module, so that it also has certain usability in high brightness scenarios such as outdoors, so that it can be displayed in all scenarios.

At the media exchange meeting, Guangfeng Technology showed the actual effect of the product to the media reporters through the real video, and obtained positive feedback from the scene.

Deliver on the prospectus promise

Guangfeng Technology is a laser display industry leading enterprise with original technology, core patents, core device research and development and manufacturing capabilities, when it landed on the Science and Technology Innovation Board in 2019, Guangfeng Technology has listed AR display as an important development goal of the company, and has given the development ideas and technological innovation points to be achieved, and predicted the technical difficulties. At that time, Guangfeng Technology wrote in the listing prospectus: "AR display is one of the future development goals of Guangfeng Technology, and the company actively explores cutting-edge technologies in this field and participates in international competition, which will serve the realization of the national innovation-driven development strategy." ”

As the next generation of mainstream display technology, AR display can superimpose virtual reality in real scenes to achieve the effect of enhancing the display. In the industrial, medical, remote communication, sports, daily information display and other aspects have great application prospects. In particular, THE GLASSES FORM AR PRODUCTS HAVE BECOME THE "NEXT TRILLION-LEVEL DISPLAY INDUSTRY" THAT HAS ATTRACTED MUCH ATTENTION IN THE CURRENT CAPITAL MARKET.

In view of the company's starting point and technical reserves for the development of AR, the person in charge of AR technology of Guangfeng Technology introduced: "From the perspective of technical architecture, AR display is closer to the projection display mode, and the imaging optics, illumination optics, display chips and other technology and industry chain resources required for AR technology research and development are closely related to the main business of Guangfeng - laser display." ”

Guangfeng Technology has been deeply engaged in the new display field for many years, has mastered the underlying core technology, AR as one of the new display technologies, has been the field of continuous attention and investment of Guangfeng Technology. "We have accumulated a lot of technology and patents in the past research and development, and we have also built a very combatable team in the field of AR, so we have the confidence and ability to innovate and form a breakthrough in these problems of AR." The person in charge said.

More technical details will be announced at the ICDT meeting

As a popular track, AR display has received the attention and layout of many well-known enterprises at home and abroad. Google launched Google glass used in C-end consumers in 2012, followed by Microsoft in 2015 launched the first generation of HoloLens glasses, and in 2019 iterated on HoloLens to the second generation, magic leap, snap, Sony, Epson, Xiaomi, OPPO and other companies have also launched their own brand of AR glasses machine, Apple, Samsung, meta in the AR field also have a very rich patent and industry chain investment.

According to IDC forecasts, in the period of 2021-2025, the AR industry will enter an explosive period, which is expected to reach an average annual growth rate of 138% and reach 21 million terminal sales in 2025.

The person in charge of AR technology of Guangfeng Technology believes that the display and extreme form available in the whole scene can ignite the market demand for AR, and it is also the key to open the ERA of AR, whether it is a B-end application or a C-end application, whether it is high-performance or lightweight, cost-effective, for the display effect of AR modules, the ultimate form, the requirements available throughout the day, are consistent, which is also the direction that Guangfeng Technology is currently focusing on research and development.

For the next step of Guangfeng Technology AR technology planning, the on-site media showed considerable concern, the person in charge said that AR is a long and wide track, there are still a large number of technical problems to be solved, the industry is on the eve of the outbreak, Guangfeng Technology will invest in the AR field for a long time, deeply cultivate technological breakthroughs, help and accompany the growth of the industry. At present, the company has achieved phased results and won some global indicators, and is expected to release more information to the media and the industry in stages this year.

The person in charge revealed that at present, Guangfeng Technology has been invited to participate in this year's 2022 ICDT (International Display Technology Conference) academic conference, and is expected to share the company's technical layout in the AR field, especially more detailed content of SPD technology, and is expected to officially launch ar optical modules in 2022.
