This week, the LED industry is still the home of UV LED and Micro LED, and there is good news in both fields. Online Jun summarizes the relevant content as follows:
The national standard "Hygiene Requirements for Ultraviolet Sterilizers" is released and will be implemented in November
On April 9, 2020, the State Administration of Market Supervision and Administration and the National Standardization Administration approved the release of 14 new national standards, including the Hygienic Requirements for Ultraviolet Sterilizers and General Requirements for Air Disinfectants. These standards are organized and formulated by the National Health Commission and the National Food and Drug Administration, and mainly involve key areas that are urgently needed for epidemic prevention and control such as disinfectants, disinfection equipment, and medical equipment.
Among them, the "Ultraviolet Sterilizer Hygiene Requirements" (GB 28235—2020), which has attracted much attention from the LED industry, will come into effect in November 2020, and formally replace the "Ultraviolet Air Sterilizer Safety and Hygiene Standards" issued in 2011 ( GB 28235—2011).
Wuhan University research found a method for growing high-quality AIN films on sapphire substrates
According to foreign media reports, researchers at Wuhan University have developed a method for growing high-quality AIN (aluminum nitride) films on sapphire substrates. The researchers deliberately designed a growth modification process to introduce voids into the AIN film to filter dislocations and relieve stress, which can grow almost stress-free AIN film on a flat sapphire substrate. This method has great potential in advancing the commercialization of AlGaN-based UVC LEDs.
American HexaTech launched a 2-inch transparent monocrystalline AIN substrate product line to help commercialize UVC LEDs
According to foreign media reports, American AlN single crystal substrate supplier HexaTech announced the launch of a 2-inch (diameter) UVC transparent single crystal AIN (aluminum nitride) substrate production line, which aims to directly support and promote the commercial production of high-performance UVC LEDs.
It is understood that HexaTech has been acquired by Stanley Electric, a Japanese automotive LED and red-ultraviolet LED expert. It mainly produces monocrystalline AIN substrates for the development of deep-ultraviolet LEDs, deep-ultraviolet lasers, RF devices and other products for disinfection and biological threats. Different application places such as detection and satellite communication. In 2019, HexaTech announced the ability to produce 2-inch defect-free AIN substrates.
LEDinside will launch the "2020 Deep Ultraviolet LED Application Market and Brand Strategy"
LEDinside will launch the "2020 Deep Ultraviolet LED Application Market and Brand Strategy" report on May 1st. The report cross-analyzes UV-C LED applications and sales channels. Its marketing channels include the home appliance market, commercial space, automotive fields, Potential markets for water purification, etc., and discuss the plans and trends of various channel brands; UV-C LED specifications and price requirements in each finished product. At the same time, a special chapter discusses special lighting market trends, covering market trends and actual case studies of sterilization lighting, food industry applications, fishery applications, plant lighting, phototherapy and curing equipment. I believe it can provide readers with a comprehensive layout for the development and sales of DUV LED applications.
AUO joins hands with Suntron to push high-resolution flexible Micro LED displays
Following the launch of the Micro LED full-color display last year, AUO and the semiconductor manufacturer Sunchuang Technology jointly announced the results of their cooperation. The two parties combined their technical expertise to develop a 9.4-inch high-resolution flexible Micro LED display.
The Micro LED display adopts LTPS backplane drive technology, with a total of more than 5.5 million Micro LEDs smaller than 30 μm, successfully transplanted to LTPS plastic backplane through high-speed mass transfer technology, reaching an ultra-high pixel density of 228 PPI, each Pixels can be driven to emit light independently.
LEDinside's evaluation of the impact of the epidemic on the development of Micro LED
According to LEDinside's observation, the current impact of the epidemic on the development of Micro LED is mainly reflected in the delay in the transportation schedule of equipment and raw materials, and the R&D of the production process may also be affected. However, because most production and sales plans have been suspended, suppliers may transform existing vacant factories from production to research and development, thereby enhancing the maturity of Micro LED technology. At the same time, display manufacturers and other terminal operators are more likely to seize the gap to seek more opportunities for cross-industry cooperation and accelerate technological development in the upstream of the industry. Therefore, LEDinside believes that the uncertainty of the industry may also bring a turning point for the new generation of Micro LED display technology.
