| 1 | Characteristics and techniques of GaN-based micro-LEDs for application in next-generation display显示文摘Due to the excellent optoelectronic properties,fast response time,outstanding power efficiency and high stability,micro-LED plays an increasingly important role in the new generation of display technology compared with LCD and OLED display.This paper mainly introduces the preparation methods of the GaN-based micro-LED array,the optoelectronic characteristics,and several key technologies to achieve full-color display,such as transfer printing,color conversion by quantum dot and local strain engineering. | Zhou Wang Xinyi Shan Xugao Cui Pengfei Tian | 2020 | Journal of Semiconductors2020，41，4： | 7 |
| 2 | High-speed long-distance visible light communication based on multicolor series connection micro-LEDs and wavelength division multiplexing显示文摘Multicolor series connection micro-LED arrays with emission wavelengths of violet, blue, green, and yellow were fabricated, and their optoelectronic properties and communication performances were investigated. The designed series connection micro-LED array exhibited the light output power of multiple milliwatts, whereas mostly keeping a slightly reduced modulation bandwidth, thus, enabling a higher signal-to-noise ratio compared to a single pixel and showing superior performance in the field of long-distance visible light communication(VLC). The achievable data rates of 400-, 451-, 509-, and 556-nm micro-LED arrays using bit/power loading orthogonal frequency division multiplexing were 5.71, 4.86, 4.39, and 0.82 Gbps, respectively. The aggregate data rate of 15.78 Gbps was achieved for the proof-of-concept wavelength division multiplexing system under a transmission distance of 13 m, which was the best data rate-distance product performance for the LED-based VLC to the best of our knowledge. In addition, the long-distance VLC based on yellow micro-LED was also demonstrated for the first time in this paper. | SHIJIE ZHU PENGJIANG QIU XINYI SHAN RUNZE LIN ZHOU WANG ZUXIN JIN XUGAO CUI GUOQI ZHANG PENGFEI TIAN | 2022 | Photonics Research2022，10，8： | 1 |
