A chip the size of a fingernail emits a dazzling green light, and with the assistance of a magnifying glass, the naked eye can clearly see the animated film being played
Entering the National Silicon based LED Engineering Technology Research Center of Nanchang University, Jiang Fengyi, an academician of the CAS Member, was very interested in visiting the latest application scenarios of scientific research achievements. He said, "This chip can be installed on one side of smart glasses and directly imaged by projecting light waves onto the lens. It has broad application prospects in the field of immersive communication
From successfully developing silicon based blue light LED materials and chip technology, pioneering the world's third blue light LED technology route, to overcoming the "Huangguang Honggou" world problem, increasing the photoelectric conversion efficiency of yellow light LED from 9.4% to 27.9%, and now focusing on micro red light research, this laboratory has incubated more than 20 photoelectric enterprises over the past few decades.
Zhao Yao, Deputy Director of Nanchang Municipal Bureau of Industry and Information Technology, introduced that today Nanchang has achieved the layout of the entire LED industry chain, with the world's largest shipment of mobile phone flashlights and mobile lighting. About one out of every three smartphones in the world uses silicon substrate technology for LED mobile phone flashlights.
Visiting the optoelectronic industry in Jiangxi, the reporter strongly felt the shining "light of innovation" here: at the National Silicon based LED Engineering Technology Research Center, all researchers have given up their administrative level and are devoted to scientific research; In order to build an open and collaborative innovation pattern, Jiangxi has integrated innovation resources from more than 30 universities, research institutes, and enterprises, established a luminescent material technology innovation consortium, and promoted scientific and technological innovation cooperation and linkage
At Jiangxi Qianzhao Optoelectronics Co., Ltd., the reporter saw through the display screen that tiny chips undergo complex processes such as photolithography, etching, and coating to form electronic components, which are sent to various markets.
Starting from a barren land, Liu Zhao, the general manager of Jiangxi Qianzhao Optoelectronics Co., Ltd., was deeply moved to become a leading enterprise in the sales of gallium nitride LED chips, ranking among the top three in the country.
Over the past 7 years, the company has invested more than 3 billion yuan, thanks to the support of the government's industrial guidance fund and guaranteed loans, as well as the technical support of the luminescent material technology innovation consortium. The company is entering a peak period of development. "Liu Zhao said that in the first quarter of this year, the company achieved a year-on-year increase of more than 20% in output value.
From the faint light in the laboratory, to the "light of new quality" on the production line, and to the warm "lights of thousands of homes" in the city... a LED chip industry cluster with a production capacity ranking among the top three in the world is constantly growing in Jiangxi.
Looking at the central region, the optoelectronic industry, including optoelectronic displays, photovoltaics, optical communication, and optical computing, is becoming an important engine for high-quality regional development.
Wuhan Optics Valley, named after "light", is famous for "light". In the 1980s, this was still the "forgotten two centimeters" on the southeast corner of the map of Wuhan.
The world's first 128 layer 3D flash memory storage chip, the country's first industrial fiber laser with a maximum power of 100000 watts, and the first 2K high-frequency PWM flexible screen in China... With innovation driving, one by one "original" and "first" were born in Wuhan Optics Valley. Nowadays, this has become the world's largest fiber optic cable research and development base, optical device research and development base, and one of the largest laser industry bases in the country.
The development of the strong photovoltaic industry in the central region relies not only on independent cultivation efforts, but also on external borrowing and attracting large and strong industries.
In a dust-free workshop of tens of thousands of square meters, neatly arranged LED bead production lines continuously produce small and crystal clear light-emitting chips. Shanxi Xingxin Semiconductor Technology Co., Ltd., located in Jincheng, Shanxi, has been focusing on building high standard intelligent production lines in recent years, and its market share in the light-emitting chip market has steadily increased.
Shanxi Transformation Comprehensive Reform Demonstration Zone signed a project with a total investment of 56 billion yuan from Jingke Energy, a leading photovoltaic enterprise; Linfen has landed a 2.5 billion yuan photovoltaic module project for Chengdu Continental Hope Group, a Fortune Global 500 company; Xinzhou has introduced a new energy battery industry project with a total investment of 6 billion yuan... In recent years, various regions in Shanxi have actively introduced optoelectronic enterprises, and a number of new and large projects have accelerated their implementation.
In the past few years, the growth trend of Anhui's photovoltaic manufacturing industry has been impressive: among the top companies in global shipment volume, 7 photovoltaic glass enterprises, 4 photovoltaic cell enterprises, 5 photovoltaic module enterprises, 2 photovoltaic inverter enterprises, 2 energy storage battery enterprises, and 2 energy storage system integration enterprises have laid out and developed in Anhui. Relying on the advantages of quartz sand reserves and convenient export location, Anhui has cultivated advantageous links in the photovoltaic glass, solar cells, modules, inverters and other industrial chains, striving to achieve a revenue of over 500 billion yuan in advanced photovoltaic and new energy storage industries in the province by 2025.
The electronic information industry in Jiangxi, including photovoltaics, LED, etc., will achieve a revenue of 1.08 trillion yuan in 2023; The scale of the optoelectronic information industry in Wuhan, Hubei has exceeded 500 billion yuan... Pursuing "light" and "electricity", innovating and developing, the optoelectronic industry in the central region is accelerating its clustering and releasing vitality, with increasingly strong momentum.
The story about 'light' is still ongoing.
