The Good News In The Field Of UV LED And Micro LED Is Worth Knowing

- Apr 30, 2020-

The national standard "Hygiene Requirements for Ultraviolet Disinfectors" is released and will be implemented from November


On April 9, 2020, the State Administration of Market Supervision and Administration and the National Standardization Management Committee approved the release of 14 new national standards, including "Hygiene Requirements for Ultraviolet Disinfectors" and "General Requirements for Air Disinfectants." These standards are formulated by the National Health and Health Commission and the State 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 new standard of "Ultraviolet Disinfector Hygiene Requirements" (GB 28235-2020), which has attracted the attention of the LED industry, will come into effect in November 2020, officially replacing the "UV Air Disinfector Safety and Sanitation Standards" issued in 2011 GB 28235—2011).


Wuhan University research finds a method for growing high-quality AIN thin 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 that introduces voids into the AIN film to filter dislocations and release stress, and can grow almost stress-free AIN films on flat sapphire substrates. This method has great potential in promoting the commercialization of AlGaN-based UVC LEDs.


US HexaTech launches 2-inch transparent single crystal AIN substrate product line to help commercialize UVC LED


According to foreign media reports, the US AlN single crystal substrate supplier HexaTech announced the launch of a 2-inch (diameter) UVC transparent single crystal AIN (aluminum nitride) substrate production line, designed to directly support and promote the commercial production of high-performance UVC LEDs.


It is understood that HexaTech has been acquired by Japanese automotive LED and red ultraviolet LED expert Stanley Electric. It mainly produces single crystal AIN substrates for the development of deep ultraviolet LEDs, deep ultraviolet lasers, RF devices and other products, respectively for disinfection and sterilization, biological threat Testing, satellite communication and other different application places. In 2019, HexaTech announced its ability to produce 2-inch defect-free AIN substrates.


LEDinside will launch the "2020 Deep UV LED Application Market and Brand Strategy"


LEDinside is about to launch the "2020 Deep UV LED Application Market and Brand Strategy" report on May 1st. The report cross-analyzes the UV-C LED application and sales channels. Its marketing channels include the home appliance market, commercial space, automotive fields, Potential water purification market, etc., and discuss the plans and trends of each channel brand; UV-C LED specifications and prices are required in each finished product. At the same time, a special chapter discusses special lighting market trends, covering sterilization lighting, food industry applications, fishery applications, plant lighting, phototherapy and curing equipment market trends and practical case analysis. I believe it can provide readers with a comprehensive layout in the development and sales of DUV LED applications.


AUO joins hands with Chuangchuang to promote high-resolution flexible Micro LED display


Following the launch of the Micro LED full-color display last year, AUO is now co-publishing the results of its cooperation with the semiconductor plant Chuangchuang Technology. Both parties combined their technical expertise to develop a 9.4-inch high-resolution flexible Micro LED display.


The Micro LED display uses LTPS backplane drive technology, with a total of more than 5.5 million Micro LEDs smaller than 30 μm, successfully transferred to the LTPS plastic backplane through high-speed mass transfer technology, reaching an ultra-high pixel density of 228 PPI The pixels can be independently driven to emit light.


LEDinside comments on the impact of the epidemic on the development of Micro LED


According to LEDinside 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 impacted. However, because most production and sales plans are currently suspended, suppliers may transform existing vacant factories from responsible for production to R & D, thereby enhancing the maturity of Micro LED technology. At the same time, display manufacturers and other terminal manufacturers are more likely to seize the gap to seek more opportunities for cross-border cooperation and accelerate the technological development of the upstream industry. Therefore, LEDinside believes that the uncertainty of the industry may also bring opportunities for the new generation of Micro LED display technology. (Organized by LEDinside)
