At present, innovative technologies in the display industry are flourishing, but there are three representatives of the next-generation display technology that are the most popular, namely: Mini/Micro LED, printed OLED and laser. What is the charm of these three innovative display technologies? What is the development trend of the industry? Mini LED and Micro LED are both wonderful Nowadays, the development path of Mini/Micro LED has gradually become clear. In terms of large size, Mini LED emits light and heat; in terms of small size, Micro LED has great stamina. Judging from the application of Mini LED, with the strong promotion of brands and industry chains, its application scenarios have expanded to many consumer electronics and IT products including TVs, laptops, tablets, and vehicle displays. "The combination of Mini LED backlight technology and LCD can make the TV have higher contrast and better brightness, and the overall visual effect has been taken to a new level. Compared with OLED panels, Mini LED backlight is not only low in cost, but also has lower display indicators in some dimensions. Not bad." Liu Tun, deputy general manager of CCID Consulting's Internet of Things Industry Research Center, told a reporter from China Electronics News. In addition, QD-Mini LED is also becoming a new label for high-end display panels. Inkjet printing may become the mainstream choice for OLED The so-called inkjet printing technology, as the name suggests, can "print" mobile phone and TV screens just like printing photos. It is understood that printed OLED has specifications and cost advantages, and the material utilization rate is higher than that of the evaporation process. It has strong product competitiveness, and the operating cost of printed OLED is smaller, and the investment is less than that of the evaporation process. "In recent years, calls for inkjet printing of OLEDs have become increasingly louder. One of the most important factors is the cost advantage of inkjet printing equipment." During the interview, Han Hongwei made a calculation. In terms of the cost of the machine itself, a G6 vacuum evaporation equipment for manufacturing OLED panels is expected to cost 100 million US dollars, while a G6 inkjet printing equipment only costs about 100 million yuan. The price difference is several times higher. . From the perspective of material cost, using the vacuum evaporation process, OLED material utilization rate is low, while inkjet printing technology can print luminescent materials at fixed points, with a material utilization rate of up to 90%. The material alone can save more than 2/3 of the cost. Screen manufacturing cost. From the perspective of a long-term production process, this is a considerable sum. As terminal demand for OLEDs increases, higher requirements are put forward for both the luminous efficiency and cost of panels. Therefore, the industrialization process of inkjet printing technology has attracted much attention.</
