On December 6, Shenzhen Textile A issued a notice saying that Shenzhen Shengbo Optoelectronics Technology Co., Ltd. (hereinafter referred to as “Shengbo Optoelectronicsâ€), a wholly-owned subsidiary, received the Shenzhen Development and Reform Commission on December 4, 2012. Shenzhen Shengbo Optoelectronics Technology Co., Ltd. Shenzhen polarized materials and technology engineering laboratory project funding application approval, agreed to rely on Shengbo Optoelectronics to establish Shenzhen polarizing materials and technical engineering laboratory, to develop new polarizer products, optical film materials and polarized light Research on alternative materials and technological transformation of raw materials, improve existing production technologies and processes, and further improve the technical level of polarizer products in China.
Shenzhen Textile A said that the project has a total investment of 24.39 million yuan to build a research and development platform for the preparation, testing, processing, standardization and engineering of polarizing materials. The construction site is located in Shengbo Optoelectronic Industrial Park, Pingshan New District, Shenzhen. The construction period is 2012-2013. year. Approved by the Shenzhen Municipal People's Government, the project was included in the fourth batch of support programs for the strategic emerging development funds of Shenzhen in 2012 (new materials industry category). Shengbo Optoelectronics received a subsidy of 5 million yuan for the purchase of equipment, improvement of existing process equipment and testing conditions, etc. The rest of the funds were self-financed by the company.
“There are only a few companies in China that can produce polarizers. Shengbo Optoelectronics is a typical representative, but it is mainly produced in the production of low-end polarizers.†Xie Jianjun, sales engineer of Junling Technology Co., Ltd., a Japanese high-end equipment agent, According to a reporter from the New Industry, the research on the replacement materials for polarizer raw materials in the laboratory set up by Shengbo Optoelectronics is unlikely to reach the level of major manufacturers in Japan, South Korea and Taiwan in the near future. The source material of polarizers cannot escape the dependence on Japanese manufacturers.
However, the person in charge of Shengbo Optoelectronics Marketing Department told reporters that the company is currently involved in research and development in medium and high-end polarizer materials, and polarizers for high-end products such as computers and LCD TVs will be the main development direction of the company in the future.
“Of course, by purchasing some advanced equipment, the improvement of process and production technology, performance and yield improvement are positive.†Xie Jianjun said that if the yield is unstable, it will lead to high cost and no market. .
