On December 8, "Yangtze Business Newspaper" reported on the research and development of Hubei Science and Technology Personnel Innovation and Entrepreneurship Competition held by Wuhan University of Science and Technology Personnel Professor Tu Guoli, Chairman of Wuhan New Material Technology Co., Ltd. and Chairman of Wuhan Optoelectronics National Research Center of Huazhong University of Science and Technology High transparency of the polyimide film won the judges of all ages, and won the first prize news, it is learned that the invention will help flexible screen localization.

The following is full-text coverage：

Yesterday, Hubei Province Science and Technology Personnel Innovation and Entrepreneurship Competition held in Wuhan, Huazhong University professor Tu Guoli with its research and development of high transparency polyimide film won the judges of all ages.

Flexible OLED display with flexible, thin anti-fall, fast response, wide temperature range of use, the increasingly wide range of applications in the smart watch, smart phones and other small size market has entered a explosive growth stage, large-size television and other displays Field, the application of flexible OLED is also steadily increasing. The key to flexible display is to use polyimide substrate to replace the glass substrate is not easy to bend, need to have excellent heat resistance and dimensional stability.

Entrepreneurship Wuhan IMIDE, Huazhong University professor Tu Guoli founded in June last year, relying on Huazhong University of Science and Technology, Wuhan Optoelectronics National Laboratory and Wuhan Institute of Optics and Technology Technology platform, focused on research and development and production of electronic grade and optical Grade polyimide product. Polyimide, the key manufacturing material for flexible display products including foldable handsets.

Professor Tu Guoli introduction, the traditional polyimide film is yellow or brown, due to the existence of intramolecular polyimide charge transfer, resulting in visible light transmittance of 70% or less. Corporate research team through the relevant raw materials for the design and production, and with its research and development distribution, developed a high transparency of the polyimide film, has produced five glass transition temperature 280 to 360 degrees Celsius of transparent poly Imide products, the visible light transmittance of the film up to 89%.

Professor Tu Guoli introduced for a long time, the domestic flexible screen subject to foreign technology, the application of this technology will help flexible screen localization. In addition, the increase of its transparency directly affects the power consumption of the device.

It is understood that the entry into the re-evaluation of 54 companies, the project covers electronic information, new materials, biomedicine, energy and environmental protection and resource environment, advanced manufacturing and other fields. The contest was awarded the first prize, the second prize, the third prize and the excellent prize on the spot through the way of road show. They were given the financial support of 300,000 yuan, 200,000 yuan, 150,000 yuan and 100,000 yuan respectively.

Relevant person in charge of Science and Technology Department of Hubei Province introduced the award-winning enterprises will give priority to angel investment, venture capital and banking institutions butt, and have access to free access to Hubei Provincial Institute of Science and Technology Public entrepreneurship space, enjoy the appropriate policy support and business help.
