After Samsung's 1110-inch Micro LED TV with a price of 1.05 million yuan was "sold out in the first batch of reservations" on Jingdong platform, Lehman Optoelectronics recently launched the 8K 163-inch Micro LED giant screen in the world, and its price of up to 1.68 million yuan triggered a huge shock in the market. Micro LED, known as the ultimate goal of display technology, is a pixel array display composed of LED chips below 50 microns and active driving arrays, which is the miniaturization and array of traditional LEDs. Compared with the current mainstream display technology, Micro LED has the advantages of higher brightness, high resolution, high contrast, high reliability, low power consumption and long service life. With the unique advantages of high transparency and seamless free splicing, it can achieve full coverage from small screen to super-large display. 01 Micro LED applications go to the consumer sector After the forward-looking layout in recent years, coupled with the active promotion of large manufacturers at home and abroad and the growth of demand in emerging application markets, Micro LEDs have gradually been applied in large displays, televisions, smart wearable devices and other fields. On June 18, the first batch of reservations for Samsung's 110-inch Micro LED TV were sold out in Jingdong. The TV uses self-luminous COB packaging, featuring large-screen frameless smart display screen/household giant screen, with a price of nearly 1.05 million yuan. On May 31, tooz announced the debut of its first all-day AR prescription eyewear, ESSNZ Berlin, at AWE USA 2022. The product features a 0.13-inch single-green Micro LED display with a resolution of 480 X 640 and brightness adjustment up to 5000 nits. On May 20, Hisense Commercial Display launched the flagship U series of Micro LED all-in-one machine Vision One giant screen, claiming to be the only all-in-one machine with real Micro LED chips that can be mass-produced in China. On May 16, Junwan Microelectronics announced a key breakthrough in the mass production process of its full-color Micro LED microdisplay, and for the first time in China, it publicly demonstrated the mass-produced full-color silicon-based Micro LED microdisplay with video pictures. On April 26, Porotech announced that it was exhibiting at Touch Taiwan the world's first native InGaN-based Micro LED displays in red, green, and blue with a resolution of 1920 X 1080 and brightness of at least 2 million nits (≥ 2M nits). In late April, INMO Air, the consumer AR smart glasses owned by Yingmu Technology, was launched for pre-sale in Jingdong. The product is equipped with a full-color Micro OLED display screen with a resolution of 640x400, a contrast ratio of 20000:1 and a field angle of 26 °, covering 100% sRGB color gamut. ……… 02 Micro LED Large Display Starts Mass Production Micro LEDs have broad application prospects, from commercial applications to consumer electronics, which are the areas where Micro LEDs can play an important role. Especially in the field of large-size display, Micro LED has officially entered the production mode. As one of the pioneers in the field of Micro LED, Liade has taken the lead in realizing the R & D, mass production and large-scale commercial landing of Micro LED. It is understood that in 2021, its newly signed Micro LED orders have reached 320 million yuan, with a capacity of 800KK/month, and it is expected to achieve 1600KK/month capacity by the end of this year. After the release of Micro LED giant screen products based on COB technology, Lehman Optoelectronics has officially extended from B-end to C-end and embarked on the road of developing consumer application market. JBD, the leading manufacturer of Micro LED microdisplays, has also made a major technological breakthrough, achieving the mass production of 500,000-class ultra-high brightness red Micro LED microdisplays, which will be conducive to the further expansion of Micro LED technology in various scenarios such as sports optics, vehicle display and near-eye display. At the beginning of June, the main buildings of some plants of JBD located in Hefei Economic Development Zone Comprehensive Bonded Zone have been preliminarily completed. The operation of the plant will help it achieve the annual production capacity of 120 million Micro LED micro displays, which can meet the blowout development needs of AR/VR industry. As a pure Micro LED concept stock, Chuang Technology has substantial orders for Micro LED. According to Li Yunli, chairman of Chuang Technology, "Micro LED large display will be mass-produced this year." In recent years, Chuang Technologies has not only launched 89-inch ultra-wide curved Micro LED displays, but also cooperated with AUO to develop 1.39-inch high-pixel circular displays, automotive displays and AR/MR applications. Li Yunli said that in 2-3 years at the soonest, we can see more business opportunities for Micro LED to be introduced into AR/MR. 03 Mass production of Micro LED accelerates the process of industrial chain Micro LED has moved from commercial applications to the consumer sector, and gradually achieved mass production, becoming an important driving force in the development of related components, equipment and processes. According to Gaogong LED observation, since the beginning of this year, many listed companies such as Ganzhao Optoelectronics, Guoxing Optoelectronics and Jufei Optoelectronics have added the concept of "Micro LED". In addition to dry lighting optoelectronics, LED chip manufacturer Huacan Optoelectronics has also made significant progress in the Micro LED sector. At present, the 6-inch flat wafer has achieved good results, in which the wavelength uniformity of the blue epitaxial wafer is 0. 62 nm, and the wavelength uniformity of the green epitaxial wafer is 0. 8 nm. Huacan Optoelectronics said, "The company has sub-micron yellow light area and Bonding/LLO/ALD/ICP/Sputter and other Micro LED operating equipment, which can provide chip, UBM and module manufacturing capabilities." Zhaoyuan Optoelectronics also has the leading integrated Micro LED design and manufacturing technology in China. "After achieving mass production of integrated monochrome Micro LED display chips, the company is committed to achieving the ultimate form of Micro LED-full color display." Wu Yongsheng, general manager of Zhaoyuan Optoelectronics, said. It is understood that the Mega Photoelectric Micro LED chip integrates 1.31 million pixels in the range of 2cm 2, with a resolution of 1284 * 1028. The display chip has a pixel pitch of 9 μm and a pixel density of 2800 PPI. As a midstream packaging manufacturer, Guoxing Optoelectronics has joined the concept of Micro LED, which also means that it has completed the initial layout of Micro LED business. As early as 2018, Guoxing Optoelectronics has established a Micro/Mini LED research center; in June 2020, it launched the first generation of Micro LED product nStar I; In October 2021, the preparation technology of high consistency pixelated quantum dot color conversion color film was successfully developed, which effectively solved the technical pain points of low yield, low light efficiency and high difficulty in transferring huge amounts of Micro LED red chips. Optimistic about the future momentum, Fucai has recently raised about 800 million yuan to expand the layout of Micro LEDs and build dedicated 6-inch wafer factories and other equipment. Shentianma has also established a joint venture with a joint venture company to build a full-process Micro LED test line from mass transfer to display modules. In addition, Kura Technologies, an AR smart glasses start-up in Silicon Valley, has announced that it has joined hands with TSMC to develop Micro LED display modules to "dig gold" in the meta-universe. In order to meet the needs of future application markets, LED equipment manufacturer Whittle Optoelectronics continues to develop and validate new Micro LED devices. According to its disclosure, "At present, Micro LED has also begun to ship in small quantities, and is optimistic about the shipment situation in the next few years." Jingzhida, a provider of testing equipment and system solutions, is also continuously investing in "research and development of production and testing technology and equipment related to miniaturized display devices", focusing on the layout of Micro LED testing equipment. Although end-use products are emerging, Micro LEDs are still in their infancy. However, as the ultimate display solution, the future of Micro LED applications and the value it can create are very attractive. Today, the mass production of large-scale displays has reached a milestone, and new opportunities for AR glasses, automotive and wearable applications will continue to be developed.
