According to a recent report by Yangcheng Evening News, mobile phones are developing towards large screens. What technological changes will there be in the future? There is no doubt that a flexible folding screen should be one of them. Under the guidance of a teacher, a team of 15 students from Shenzhen Polytechnic recently tackled the main technical problems of flexible screens for mobile phones. At present, the flexible screen display life has been increased by 30% and folding times increased by 4 times. The product is expected to be in small-scale mass production this autumn.
On June 26, 15 students from this scientific research and innovation team were busy in an office in Houde Building of Xili Lake Campus of Shenzhen Polytechnic. "The samples we developed have been sent to a third-party testing agency for testing. Everyone is looking forward to it." Team leader Liu Kai said excitedly.
Liu Kai, a sophomore in the School of Electronics and Communication Engineering at Shenzhen Polytechnic, is the "CEO" of the team, along with other students from different schools and majors who work in different positions such as technology, finance, marketing, and brand promotion. With the strong support of the school and the school, students set up a company named "Shenzhen Rike Optoelectronics Technology Co., Ltd." for this project. The company's articles of association and management system were set up to operate according to the corporatization of the project.
Why did you think of forming a team to tackle the technical challenges of flexible displays? According to the instructor Dr. Xue Yan, there is a contradiction between large screen and miniaturization of mobile phones at present. The mobile phone should be portable while the bigger the screen is the better, and flexible technology can better solve this problem. At present, the existing flexible screens in the market have bottlenecks such as short folding life and insufficient display brightness. For example, after more than 100,000 folds, the folding position of the screen is prone to wrinkles, white marks and color problems.
In view of the above pain points, under the leadership of Dr. Xue Yan, we selected key technical students and set up a special student team to tackle technical problems.
As a high-end talent introduced by Shenzhen Polytechnic, Dr. Xue Yan is a big player in the field of flexible display. He is an outbound postdoctoral fellow at the School of Information Engineering, Peking University. He used to work at China Star Optoelectronics, a well-known display enterprise in China, engaged in cutting-edge technology research and development. Benefiting from the complete education chain of production, study and research established by Shenzhen Vocational College over the years, the arrival of Dr. Xue Yan has further enriched the faculty strength of the School of Electronic and Communication Engineering.
From product design, process improvement to material optimization, the entrepreneurial team has overcome many problems in flexible display technology, including integrated circuit design, layout design, display panel design and other technical links. Finally, the technical problems have been broken through one by one, and the display life of the flexible screen has been increased by 30%, the folding times have been increased by 4 times, and the brightness has reached the standard of the similar hard screen of mobile phones. It has obtained a number of national patents.
At present, the product has entered the sample testing stage and is expected to carry out small-scale mass production in September. The team has also received several intent orders from related manufacturers, which is expected to be followed by mass production and market application.
In Mr. Xue's opinion, this technology has a wide application value in the flexible field, not only applied to the flexible display screen of mobile phones, laptops, wearable devices, etc., which can meet the different needs of users in multiple scenes.
