Lijing Microelectronics Technology (Jiangsu) Co., Ltd. Ms. Zhou Jia, Vice President of Micro LED Research Institute, brought a speech on the theme of "Discussion on the mass production technology of Mini/Micro LEDs and its industrial chain". She said that Lijingwei continues to be optimistic about Micro LED and actively develops industrial chain layout, and continues to make progress in R&D. It is expected that the expansion plan will be launched to 1,600KK per month by the fourth quarter of 2022. At the same time, she shared some of Lijingwei's experience in huge transfer technology. She said that the company's current accumulation of contactless huge transfer technology can fully meet the implementation and application of semiconductors and glass bases, while Lijingwei is more based on laser huge transfer technology. Through huge laser transfer, chips of more sizes can realize the process of solid crystal transfer.However, there are still technical difficulties. Whether it is an excimer laser or a physical DPFS, a core laser or a boring state, laser energy adjustment needs to be combined with the production line process to match production needs.

Mr. He Jun, general manager of Nanjing Xinshiyuan Electronics Co., Ltd., gave a keynote speech - "Core Display New Shiyuan New Era". Mr. He introduced the future trend of the silicon-based micro display market and its current main layout of silicon-based OLED chips and Micro LED chips. Among them, Tianmu III-010-A is the first Micro LED chip independently developed by Xinshiyuan, which is mainly used in emerging market fields such as lightweight AR glasses, automotive head-up display , and smart car lights. Mr. He also called for the establishment of an AR/VR industry alliance, the construction of an AR patent pool, XR core machine linkage technology center and joint laboratories, and promote the development of the AR/VR industry.

Mr. Sun Haiwei, the director of the Development Center of BOE Jingxin Technology Co., Ltd., gave a keynote speech - "MLED display technology and application trends". Mr. Sun said: Excellent display products need to have the following characteristics. First, perfect picture quality, higher brightness and color gamut to improve the realism of picture quality and the better sense of reality of customers. Second, more functions are integrated on the basis of display to improve the intelligence and convenience of display and better human-computer interaction. Third, in terms of appearance design, it is necessary to take into account both fashion aesthetics, which is lighter and thinner, providing convenience for the design of the entire machine. Fourth, in terms of performance, the product's increasingly low power consumption is an indispensable requirement. The ultimate goal of the display field is to display more content with less energy consumption. In addition, high cost performance is also an indispensable aspect, providing users with quality, low-cost services and products.

Beijing Xianxin Technology Co., Ltd. General Manager Ms. Yan Chenghui gave a keynote speech - "Mini LED LCD is challenging OLED in the field of HDR display." Mr. Yan analyzed the current brand's product line strategy and proposed to improve the display effect of Mini LED backlit LCD products through HDR functions, and jointly create high-end image quality effect with OLED. At the same time, he proposed to use Tcon to combine Local Dimming solution and AM drive to achieve the matching of backlight and front-end display, achieving higher display effects.

6 Director of Technology Innovation of Shenzhen Aibisen Optoelectronics Co., Ltd. Ms. Xu Mengmeng, delivered a keynote speech—“ Aibisen Mini/Micro LED display technology layout”. Mr. Xu reviewed the evolution trend of large-screen technology and proposed the competitive advantage of Mini/MicroLED in the market above 100 inches.

Shenzhen Guangshengde Technology Development Co., Ltd. R&D Director Xu Jinhong gave a keynote speech - "Mini LED market prospects and new opportunities for equipment companies". Mr. Xu said: Mini/Micro LED not only develops rapidly in the direction of Mini LED direct display and Mini LED backlight, but will also build its own advantages in the healthy light source market. Among them, Mini LED flexible light strips will have the opportunity to completely subvert and reshape the traditional LED industry chain. The evolution of these markets has driven the size of LED light-emitting chips to become smaller and smaller, the chip packaging requirements are getting higher and higher (from patches to solid crystals to various forms of huge transfers), and the degree of automation requirements for product assembly, aging and testing are getting higher and higher. Guangshengde has launched a more convenient Mini LED intelligent aging test production line, which can realize the advantages of automatic loading of programs, accurate loading, constant temperature aging, automatic testing, over-temperature warning, flexibility compatibility, safety and reliability. Mr. Liu Chengzhi, senior analyst at

, gave a keynote speech "Analysis of Mini/Micro LED Market and Brand Strategy", pointing out that medium-sized IT applications are the largest application market for Mini LED backlight, but because Apple accounts for too high proportion, there is a potential impact of RGB AMOLED, and it is necessary to specify a clear customer strategy, and you can also pay attention to the e-sports market in the non-Apple camp. TV will become the largest single market for Mini LED backlighting, and can drive technological improvement and supply chain cost reduction through economies of scale, and feed back to other application markets.The mass-produced models of vehicle Mini LEDs will start to be shipped in large scale in 2023, becoming the third pole in the development of Mini LED backlight products.

Micro's large-scale mass production technology and technology are not yet mature. In the short term, the market mainly focuses on large-sized splicing screens and giant screens. Especially the future development of AR has the opportunity to drive the rapid growth of Micro LED. Micro LED can combine the advantages of LCD and AMOLED, and the in-vehicle market will become the main battlefield for Micro LED to make efforts in the future.
