Mini LED and Micro LED are regarded as the next-generation display technology revolution, which not only brings ultra-clear display effects, but also provides new development opportunities for the entire LED industry chain. The High-tech Industry LED Research Institute (GGII) expects the application market size of Mini LEDs to reach 500 million yuan in 2018. The backlight of mobile phones will be the vanguard of the application of Mini LEDs. As the cost decreases, the Mini LEDs will gradually show to the display and Zhongda. Size backlight penetration. Regarding Micro LED, GGII is expected to see explosive growth in 2020, and the global market is expected to reach 1.41 billion yuan in 2020. With the domestic and foreign technology companies, LED companies, display companies to increase the layout of Micro LED, Micro LED technology, the market is expected to usher in rapid development. Based on the technical advantages of Mini LED and Micro LED and the market's momentum, the LED industry chain has set off a layout boom. As a leading semiconductor lighting and testing and device company in China, Ruifeng Optoelectronics has also achieved corresponding breakthroughs and progress in new display technologies. Recently, in front of many research institutions, Ruifeng Optoelectronics deputy general manager Liu Zhi, deputy general manager Yan Xiaoming, deputy general manager Peng Xiaoling, etc. gave a detailed introduction to the company's Mini LED and Micro LED. Q: The theme of this investor exchange meeting is MLED. Can you introduce the basic situation of MLED? A: We call MLED, including Micro LED and Mini LED. Since the beginning of the "M" letter, Ruifeng first proposed the two together as MLED. The LED products were packaged from the earliest 300mils of small and medium-sized chips, and developed into a high-power package for general-purpose lighting of large-scale chips of around 1600mil in 2004. Due to the continuous improvement of chip technology, since 2003, the more economical 300mil class chips have returned to the market, and the medium and small power packages have successfully entered general lighting and began to explode. The general lighting market is maturing and the standardization is basically completed. As a result, in 2016, the industry began to explore the application direction of smaller-sized chips, and proposed the concept of Micro LED. However, due to the high threshold and technical obstacles of Micro LED, it is still in the laboratory stage and is really starting to commercialize. Look at at least 500 more days! As a transition technology, Mini LED not only realizes the technical characteristics of products that can be used for area dimming, but also can be prepared in a short period of time with the mature LCD screen industry chain. Q: What are the advantages of MLED compared to traditional LED and OLED? A: Compared with traditional backlight applications, Mini LED can achieve regional dimming in a smaller range. Compared with the traditional backlight design, it can achieve better brightness uniformity and higher in a smaller mixing distance. Color contrast, which in turn achieves ultra-thin, high color rendering and power saving of the end product. Compared with OLED, Mini LED also has great advantages in reliability. For display applications, RGB Mini LED overcomes the defects of wiring and reliability of the front-loading chip, making it possible to further reduce the dot pitch of the display screen, corresponding terminal products. The visual effect has been greatly improved. In addition, the use of Mini LEDs with flexible substrates can also achieve high-quality display of curved surfaces, and has a very broad market in some special modeling requirements (such as car display). Q: Can you share the core technology highlights of MLED? A: Ruifeng Mini LED product development benefited from the company's continuous accumulation of new technologies and product development results. The core technology highlights are: (1) Mini LED chip transfer and bonding technology; (2) KL pattern coating Technology; (3) Micro Lens array mixing technology. Q: What is the cost of MLED? A: The price of OLED is about 4 times that of LCD, and MLED is in between. The cost of MLED products is between 40% and 60% of OLEDs. Q: What is the market expectation for MLED? What challenges can MLED face? A: Mini LED is a technology transition product of Micro LED. It is technically ready. The LCD screen with it has a complete and mature industrial chain. In the next 1-2 years, Mini LED is expected to be a big hit. Of course, there are still some challenges at the current stage, such as efficiency and yield, and the implementation of drive technology. From the perspective of the process route, the Mini LEDs all use the small size of the flip-chip Bonding, and the Bonding efficiency and the straight-through rate also have room for improvement during the operation; from the perspective of product application, the seamless splicing and driving technology of the large-size backlight products are also In continuous optimization. Q: What is the company's progress and industry status in the MLED field? A: The company exhibited a 55-inch Mini LED TV at the Shanghai International New Display Technology Exhibition in 2018. This product won the 2018 Innovation Display Product Award. It can be said that our Mini LED backlight product technology is already in the leading position in the industry. status. In addition to the large-size backlight of the TV, our Mini LED backlight technology is also used in the development of MLED small-sized backlight surface light source products and very small pitch M-DISPLAY products, and has made substantial progress. At present, our Mini LED small-size backlight products have completed the acceptance of samples and mass production processes, and have a sample production capacity of 3K pieces per month. Now we are preparing a fully automatic production line. Shenzhen Innovative Cloud Computer Co., Ltd. , https://www.xcypc.com
