According to Professor Li Shiwei, the application of IR/UVCLED has already existed, but its marketization is still in the preliminary stage of exploration, and it is still a blue ocean market. It is far from the turning point of mass production and the explosion of the industry. There are also technical aspects. A lot of room for improvement.
He believes that most of the current IR LEDs are used in the military and other special fields, but will be extended to the civilian population in the future. The future of IR LED will be locked in portable products, which can be used in night vision, pupil recognition, heartbeat detection, cosmetics and biomedicine. In contrast, UV LEDs will be used more in the industrial field, and will be much larger than IR LEDs in terms of market size.
The wavelength range of ultraviolet light is 200nm-400nm, and the application scenarios of these different wavelengths of ultraviolet light are also different, so they are divided into three categories: UVA (320nm-400nm), UVB (280nm-320nm) and UVC (200nm-280nm) . UVA is mainly used for polymer curing, such as quick-drying of printed ink, second-drying of nail polish, and fast curing of 3D printing. UVB is mainly used in biomedicine, such as the treatment of skin diseases. UVC is mainly used for the disinfection of gases and fluids.
Today in the 21st century, the backlight is turned on very quickly, new skills and new products are constantly being introduced, LED lamp beads are gradually entering industrialization, and there is a certain plan. Compared with CCFL, LED has obvious energy-saving advantages, and LED lamp beads are still in demand. The improvement is that domestic upstream supporting factories cannot keep up with the international situation. The improvement of skills exchanges and interactions and the application of sample products are a great obstacle to the entry of LEDs into the scope of large-scale LCD backlights. They are one of the important parts of LCD products. The backlight is turned on quickly, and new skills and new products are constantly being launched.
Meanwhile, the market share of LED (light-emitting diode) backlights is gradually increasing. CCFL (Cold Cathode Fluorescent Lamp) backlights have been used in notebooks, flashers, TVs and other products. Since 2008, the use of ultraviolet LED lamp beads in notebooks and flashers has been expanding. Relevant statistics flashed, in the first quarter of 2009, the shipment of UV LED lamp beads was 8 times that of the same period in 2008. Together with the CCFL to unify the world in the field of LCD TV, following the launch of the deep-ultraviolet LED lamp bead TV in 2008, LED lamp bead TV products in domestic shopping malls have also sprung up in the market.
