On the morning of March 30, 2018, Academician Li Shushen, Academician of the Chinese Academy of Sciences, visited Southern University of Science and Technology. Prof. Sun Xiaowei and Professor Liu Zhaojun of the Department of Electronics presented the latest Micro-LED research results for Li Yanshi - Flexible transparent double-sided. display Tricolor Micro- LED Display.

In the same period, Prof. Zheng Youyi, a member of the Chinese Academy of Sciences Professor Shen Bo of Peking University, visited Southern University of Science and Technology, and he made a presentation entitled 'Some Thoughts on the Development of Micro-LED Technology' and 'The Great Adaptation of Nitride Semiconductors and Their Quantum Structures. “Quality Epitaxy” invitation report. After the report, Academician Zheng and Prof. Shen were hired as the consultants of the Micro-LED Research Group of the Southern University of Science and Technology. The following figure is the letter of the subject leader Dr. Liu Zhaojun.

It is understood that Liu Zhaojun's team is one of the first teams in the world to develop Micro-LED technology. The team has made significant progress in the field of Micro-LEDs. In the past ten years, his team has developed 7-generation Micro-LED technology, from PM Micro- LED arrays to AM Micro - LED arrays, transfer large area technology from small area chip to module, from monochrome to color, from UV micro LED to blue light, green light, red light Micro- LED display , And developed the world's first to go back to the backlight Micro - LED Projector Micro-LED display chips with integrated optical communication capabilities are also available.
This time, the introduction of flexible, transparent double-sided display of three-color Micro-LED Display is leading the international level and will enable Micro-LED flexible to achieve China's zero breakthrough. All along, many people think that Micro-LEDs currently exist. Two important issues, one is high cost, low yield, and difficulty in mass production; the other is the fact that Micro-LED technology is difficult to be flexible and is a factor that severely restricts the application of Micro-LED technology. The flexible, transparent double-sided display of the three-color Micro-LED Display of the university's Liu Zhaojun team announced a flexible puzzle solution.
When it comes to flexibility, it has to mention the next generation of Micro-LED campaigns Display technology of OLED , This is also a topic that can't be avoided. Their biggest difference is that the OLED luminescent material is organic, while the Micro-LED luminescent material is inorganic. The characteristics of the material itself determine the advantages of the Micro-LED to the OLED. Micro-LED has The higher electro-optic conversion efficiency, in other words, the Micro-LED is more energy-efficient, at the same time it has less heat, the material is more stable, and there will be no short-lived OLED screens and burning problems.
but AMOLED The greatest advantage that has been admired for a long time is that it is flexible and foldable. Although the flexibility of AMOLED is not fully realized at present, it is considered to be the fundamental aspect of next-generation display in terms of its flexibility. In the past, this has always been Think of it as a pain point for Micro-LEDs, and this time making a breakthrough, the flexibility advantage of AMOLED is no longer obvious.
Therefore, the biggest impact of Micro-LED breakthrough is the OLED industry. In fact, OLED screen Samsung was in use about 5 years ago, but it didn't really take off until the launch of iphoneX. Therefore, if Apple turns to MicroLED, it should produce OLED industry. Larger impact. At present, the largest application of OLED is still the mobile phone screen, and the only application area that can support OLED's huge investment right now is only the mobile phone. Once the prospect of this application is in doubt, then whether there will be a large amount of funds will enter the OLED field. There will be doubts, but without a lot of capital investment, trying to reduce costs is a difficult problem. Therefore, when considering the application of OLEDs, everyone will also consider the feasibility of Micro. The panel industry's emphasis on Micro will also be greatly enhanced. This in turn will promote the development of micro technology.
