Recently, Corning Incorporated said it has decided to terminate the development and mass production of the synthetic Green Laser because of the limited development of the synthetic green laser market with the rapid development of native (direct) green lasers. .
Matt's partner Mic rovision, Inc. announced almost simultaneously with Corning that the company has successfully integrated direct green laser samples from two leading manufacturers into the prototype of the pico projector. Manufacturers from Germany, Japan and the United States will launch direct green lasers in the next 12-18 months.
Yaguang also said that once the green laser can be produced by the chip process, the production cost is expected to drop sharply, and Microvision products are expected to enter the mobile phone market.
Sumitomo recently announced plans to continue investing in products with growth potential, including native green lasers. Nichia Corporation, a Japanese LED manufacturer, has also successfully developed a green GaN-based laser diode based on gallium nitride (GaN). The direct-emitting green laser produced by GaN epitaxial wafers and chip technology can not only achieve hundreds of millions of annual output, but also be smaller, lighter and cheaper than the current green lasers on the market.
The industry has expected that Sumitomo (SEI), KAAI (UCSB) and OSRAM will produce direct-emis ssion green laser diodes that are more suitable for mobile phones in 2011-2012.
Road Traffic Signs are graphical symbols that display traffic regulations and road information. They can make traffic regulations visually, concisely and concisely expressed. At the same time, they also express the content that is difficult to describe in words. They are used to manage traffic and indicate the direction of driving to ensure the smooth flow of roads and the safety of driving. Applicable to highways, urban roads and all special highways, with the nature of the law, vehicles, pedestrians must comply with.
