[Hardcore stubborn master]Micro LED display industry has a promising future


On June 17-18, at the 2021 World Display Industry Conference held in Hefei, Anhui, a set of data was revealed: In 2020, my country’s new display industry’s direct revenue will reach 446 billion yuan, accounting for 40.3% of the global market. Ranked first in the world. China’s display industry has moved from a counterattack to a leading position, which is the result of the continuous efforts of scientific researchers over the past 20 years. However, as the times go by, the world is also facing a new pattern, which also means that China’s display industry will face greater challenges in the future. Ouyang Zhongcan, an academician of the Chinese Academy of Sciences, said: “There is always a direction to follow, but in which direction is the leader to run? This is more difficult.” The obvious advantages of Micro LED At present, the entire electronic products have become highly integrated, and we are striving to develop in the direction of miniaturization and high integration. From chips to applications, their essence is miniaturization. Judging from the current trend, the future will display and touch Integration of control and processing chips. The miniaturization and integration of chips can achieve huge functions, while Micro LED is a two-dimensional pixel matrix of LED miniaturization and matrix. Its core technology has two main steps: miniaturization process technology and mass transfer technology. Miniature process technology: Mass transfer technology: Micro LED is actually a semiconductor technology, so its manufacturing is related to semiconductor manufacturing. Therefore, the semiconductor manufacturing can be integrated with the processed chips and substrates. Therefore, this technology is not in terms of brightness or high integration. , Both have obvious advantages. At present, the 5G transmission technology has been completely solved, and high-quality pictures can be realized from the camera side or the transmission side. Not only that, the processing of the most terminal chip has also been solved. At present, the pressing question is whether the display device can match the higher and higher picture quality picture display. Micro LED is a direct display of RGB. The width of RGB wavelength is about 20 nanometers. Due to the narrow wave width, the color gamut of Micro LED display is basically above 110%. In addition, Micro LED also has a very fast response speed, OLED response speed is microsecond level, and Micro LED response speed is nanometer level. These two features provide relatively high-definition picture quality and display effects, as well as a very high refresh rate, which is obviously incomparable to LCD and OLED. From its actual working environment, Micro LED still has great advantages. First of all, the working temperature range of Micro LED is very wide, from -40 degrees to 80 degrees, it can work normally. Secondly, the country’s semiconductor strategy is clear. Whether it is semiconductor materials, equipment, or talents, it is currently in a stage of rapid development. The semiconductor nature of Micro LED makes it destined to have extremes whether it is a chip, a giant switch or a terminal and driver substrate. Big breakthrough. In addition, according to the current technology of OLED, its maximum transmittance and transparency can reach 30%-40%. This is the actual situation of current industrialization, while Micro LED can reach 80%-90%. Therefore, in terms of transparency, Micro LED LED has the advantage of compaction. “As the end field, we are the end field of the product. We are optimistic about the excellent performance of Micro LED, so we will take the Micro LED route.” said Lin Weihan, general manager of the Display Design and Industrial Design Center of Konka Group Co., Ltd. Future solutions in the field of electronic display: Micro LED In terms of capital support, in 2020, about 5 billion U.S. dollars in the world will be invested in Micro LED display technology, while China invested 1.3 trillion in new displays last year. From the Micro LED industry where 70 billion yuan has flowed so far this year, the inflow of capital market and the breakthrough of semiconductor technology, the progress of Micro LED industrialization and commercialization is definitely worth looking forward to. In the field of science and technology, with the opening of 5G networks, information technologies such as big data, cloud computing, and artificial intelligence have also entered new horizons. Information display has also become an indispensable part of the 5G information technology ecosystem. The needs of the display industry have become The fertile ground for the rapid growth of the Micro LED display industry. Zheng Youyi He engraved Ke Ke, Guohe X Yun Xie> Na Rong Xing Xing ⒄ Micro LED display technology industry is at the right time, and Micro LED display technology will trigger revolutionary changes in the display field, which is expected to reshape the new pattern of the display industry, and different display technologies will play their own roles. Advantages, open up their own development areas and application scenarios. Micro LED’s large-size, high-resolution direct display and direct-lit partition backlight technology are widely used, especially when super-large, ultra-high-definition high-end engineering displays enter consumer displays, the market space will be huge. Consumer panels including smart phones, wearable devices, TV screens, as well as car displays, public displays including outdoor large screens will all be the future development trend of Micro LED. Except for foreign companies such as Sony, Samsung, Apple, and Google, domestic Companies Sanan, BOE, and China Star Optoelectronics have all made arrangements in the direction of Micro LED. At present, the Micro LED display industry has focused its attention on the four dimensions of vehicle, AR, mobile phone, and TV. Lin Weihan said that it is expected that from 2023, smart watches, AR and other applications can be mass-produced, and mobile phones are more sensitive to users. Gao’s products may not be commercialized until 2025. The development of the Micro LED display industry requires the upstream and downstream collaborative efforts of material manufacturers, equipment manufacturers, terminal manufacturers, high-efficiency scientific research institutions, and talent joint training platforms to work together to solve all aspects of Micro LED mass production. Only in this way can Micro LED It is possible to achieve real commercialization sooner. Although the future is full of thorns, the current domestic industrial technology route is clear, and the industrialization of Micro LED is bound to be expected
