Speaking of the basic principle of LED翡翠棋牌平台 portable display, Xiaobian found a lot of information to summarize the following information to share with everyone:
In the LED portable display manufacturers, many have production technology, but as a professional top LED portable display Manufacturers must share with you the basic principles of our Shenzhen Weichensi custom portable display manufacturers!
LEDBasic principles of portable display?
Light-emitting diodes (LED) are optoelectronic components made of tri-five compound semiconductors, and their core is PN knot. Under forward voltage, the electrons are injected into the P area by the N area, and the holes are P area is injected into the N area, and some of the minority carriers entering the other's area are combined with the majority carriers to emit light. The material properties (forbidden band width) that form the PN junction determine the wavelength of the emitted light, which determines the color of the light.
LEDPortable display features
The main features of LED are: small size, low power consumption, long service life, high brightness, low heat, environmentally friendly and durable. Operating at the right current and voltage, LED can last up to 10 10,000 hours.
The middle reaches are mainly chip design and processing. Midstream manufacturers design the device structure and process according to the performance requirements of LED, diffuse through the epitaxial wafer, then metallize the film, then photolithography, heat treatment, metal electrode formation, and then The substrate is polished and polished to be cut.
LED The basic principle of portable display? I believe that everyone can understand the introduction of Xiaobian, if you need to buy our portable display friends, you can directly buy directly on the official website of Jingdong and Tmall connection, if you buy more than you can directly play the official website phone to enjoy the factory direct price .
