In recent years, the display industry market continues to expand, the rapid development of technology, LCD, OLED, Mini LED, micro-LED and other technologies coexist pattern. LCD technology has been developed for many years, and related technologies and industries at home and abroad have been quite mature, but the shortcomings of the overall module, low contrast, have gradually failed to meet the needs of the frontier market. Currently, OLED has achieved mass production in smart phones, tablets, vehicle-mounted displays and other applications by virtue of its thin and flexible features, and occupies an increasing market share. And Mini/ micro-LED technology, namely LED miniaturization and matrix technology, only a few companies can achieve partial mass production.







The Mini/Micro-LED technology, like OLED, can address each pixel individually and drive the luminescence (spontaneous light) separately, and uses inorganic gallium nitride material for longer screen life. Usually LED chip size of 50-100 microns is called Mini LED, LED chip smaller than 50 microns is called micro-LED. In comparison, the Mini LED display technology is relatively mature and will gradually begin commercial penetration in 2020/2021. Micro-led is still in its infancy due to its high technical specifications. Micro-led and massive transfer are key technical difficulties.

Mini/Micro-LED technology is regarded as the future of new display technology, among which micro-LED is regarded as the ultimate solution of the screen. Apart from the existing cost and technical factors, Mini/Micro-LED has outstanding advantages compared with OLED and LCD: long screen life, low power consumption, high brightness, fast response speed, large viewing Angle, thin and thin, simple structure, almost no light consumption, etc.

2021 is regarded as the first year of Mini/Micro-LED commercialization by industry experts, and with the recent popularity of 5G+8K, 5G+AR/VR and metasexes, Mini/Micro-LED commercialization is once again put on the agenda. Recently, many companies have been increasing the Mini/Micro-LED field, starting a boom in R&D and investment.

Shin-etsu Chemical and Toray Industrial developed key equipment

It can reduce the cost of micro-LED mass production

Toray Industries and Shin-etsu Chemical have developed a device that reduces the key manufacturing process of micro-leds by 16 percent. The device automatically tests, selects, and installs micro-LED materials onto the substrate. Using patented technology originally used in semiconductor testing equipment, a special fluorescent lamp detects defective leds on the wafer before installing the micro-LED material on the substrate.

In this way, panel makers reduce repair work. Lasers are used to efficiently transmit and align the leds on the substrate, again saving time. Shin-etsu's equipment separates leds from raw materials and installs leds onto substrates. Micro-led transfer and connection for a 50-inch 4K display takes about 15 minutes. These steps, which make up about 90 percent of the process, typically take six hours to make a large micro-LED panel, but the new device will cut that time to one hour. (News source: Jiwe.com)
