On February 21, the reporter of the theme of "Striving for a New Journey and Building a New Era of Meritorious Service" conducted an investigation and visit in Nanyang City, Henan Province. In China Optics Group Co., Ltd., various specifications of colorful coatings can be produced here, which are widely used in high-end products including Lycra, Tesla, Canon, Fuji, as well as Huawei, Xiaomi, VIVO, OPPO and other big brands.

Why does the shell of the mobile phone change color after coating under poplar light or light? This is inseparable from a key material, called a synchromatic prism. Shine it with the light of your mobile phone, and three colors will appear: red, green, and blue. When it works in the projector, the red, green and blue tricolor images are incident from three directions, reflected by the trichromatic prism, and ejected from the same direction, forming a color image.

Li Zhichao, chairman of Henan Plating State Optoelectronics Co., Ltd., said that the products mainly include optical components, lenses and modules, vehicle AR-HUD and central control displays, projectors, security monitoring systems, photoelectric defense products, etc., with an annual production and sales of 160 million precision optical parts, 5 million optical lenses and modules, 1 million optical engines, 400,000 projectors, and is the main market supplier of AR optical waveguide devices, and the brand supplier of automotive AR-HUD head-up display PGU module market. The global market share of digital projection precision optical components ranks first, the functional coating technology and scale manufacturing capability are in the industry, and the digital micro-display technology and scale manufacturing capability are the first in China.
"International big names and we have cooperative relations, such as Germany's Lycra, Zeiss, the United States' Youpai, Tesla, Japan's Epson, Fuji, Sony, Canon, Nikon, Taiwan's BenQ, Yangming, Chinese mainland Huawei, VIVO, OPPO, Hikvision, Jimi, Nuts, Alibaba, Xiaomi and so on." Li Zhichao said.
It can be said that the number of products of China Optics Group Co., Ltd. directly determines the output of the above-mentioned international big-name products, which not only solves the problem of independent brands being "stuck in the neck", but also deeply affects the industrial chain supply of the world's big names.
Why are they the ones who succeed? Li Zhichao analyzed, first of all, the development of the South Sunshine Electric Industry originated from the construction of the third line of the national defense and military industry in the 1960s, which is an important force in the development of the national defense military optoelectronic technology and an important development base of the national optoelectronic industry, with a deep foundation, and the technologies and products represented by optical components, optical functional films, optical engines, digital micro-display projection machines, etc. have formed the characteristic advantages of the development of the South Sunshine Electric Industry. Secondly, Nanyang's natural ecological environment is unique, and its temperature and humidity environment and stable crustal plate structure provide precision optical manufacturing with unique ecological environment advantages that other cities and other regions do not have. Finally, a group of optoelectronic enterprises with industry influence and the talent team cultivated have formed a relatively complete industrial chain advantage from key equipment, new materials, core technologies and leading products through more than 50 years of technological accumulation and unremitting struggle, and Nanyang has broad prospects for the development of optoelectronic industry.
