2011 on January 31, JingHaiXian held in tianjin optical valley park was inaugurated, lithium ion battery anode projects, monocrystalline silicon project, photoelectric information industry base project, and a number of photoelectric industry project concentrated signing settled here, this symbolized with world-class level of optoelectronic industry clusters and optoelectronic products manufacturing base of formal rev built.

Tianjin optical valley industrial park depends on the tianjin son tooth circular economy park has planned industrial land resources and long-term planning, with a total planned area of approximately 4 km2, mainly develops the laser field, photoelectric sensor field, energy photo-electron fields, optical field, photoelectric instrument field five fields. Strive to 2015, production scale of 500 billion yuan, realize breakthrough employment population 20,000 people. At present, this park construction has been completed road, communication, water supply and other related infrastructure, realize five a flat. This year will be established tianjin optical valley construction management institution and tianjin optical valley expert advisory committee, and issued series support policies, and gradually improve the complete service system, key industrial guidance leading enterprise, bibcock of investment projects optical valley. After the completion of the project, will become our country northern important optoelectronic industry in refugee camps, and laser, photoelectric sensor, optoelectronic devices and equipment, LED, solar battery fields with international competitiveness to form a number of giant enterprises.

According to information, new settled in three photoelectric industrial projects with total investment of over 10 billion yuan, of which, lithium ion battery anode project will construction began in March this year, the project after production, lithium ion battery anode an annual output achieves 1500 tons, achieved sales revenue of 4.5 million yuan, tax turnover, 1500 yuan. Main products used in the manufacture of monocrystalline project photovoltaic solar battery, microelectronic device and LCD conductive glass etc. Photoelectric information industry base after the completion of the project will be formed test, production, sales integration of complete management system.

Tianjin optical valley park was unveiled marks the construction of optical industrial park made substantive steps. In recent years, along with the rapid development of electronic information technology and development of binhai new area open the quickening pace of, the city has formed a comparatively complete information industry chain, a batch of innovative enterprise growth, talent technical resources unceasingly strengthens, logistics unceasing enhancement, the traffic environment for tianjin optical industry development provides good conditions. Tianjin industrial layout planning are presented based on the construction JingHaiXian optics, vigorously develop optoelectronic and optical high-end industry by letter, the municipal committee and JingHaiXian joint efforts, in the help of experts, compiled by the JingHaiXian optical industry development planning for the further development of the park, and pointed out the direction of the park carrier construction unceasingly consummates, for enterprise’s strengthe provided protection. Vigorously develops the optical industry, strongly construction for tianjin optics, tianjin adjust the industrial structure, promote industry development level is very significant. Next, city by faith in the planning of the authorities will lead under, grasp project introduction and project start early, prompting zhongtai built, become a symbol of the city and even the whole country park.

According to information, tianjin optical valley industrial park depends on the tianjin son tooth circular economy industrial district has planned industrial land resources and long-term planning, with a total planned area of approximately 4 km2, mainly develops the laser, photoelectric sensor, energy optical-electronic, optical communication, photoelectric instrument such five fields, strive to 2015, production scale of 500 billion yuan, realize breakthrough employment population 20,000 people. At present, this park construction has been completed road, communication, water supply and other related infrastructure, realize "five leveling". This year will be established tianjin optical valley construction management institution and tianjin optical valley expert advisory committee, and issued series support policies, and gradually improve the complete service system, key industrial guidance leading enterprise, bibcock of investment projects optical valley. After the completion of the project, will become the important action in north China in refugee camps, optoelectronic industry and laser, photoelectric sensor, optoelectronic devices and equipment, LED, solar battery fields with international competitiveness to form a number of giant enterprises.
