Unilumin’s Unano series of high-end rental market won the highest honor of the red dot award "best of best". This small tube would enable the very first televisions to be built and create the LED display industry that has advanced in leaps and bounds from its humble beginnings.įocusing on products and technology innovation, Unilumin is one of the first group of companies in the LED display industry to lead the technology trend of fine pitch, LED super TV, mass production of Mini LED 0.9, etc. At the same time, it's no doubt that LED display is one of the most important applications of LED. And this is the light emission’s principle of the LED.ĭue to its long lifespan, energy-saving, no UV radiation, and other advantages, LED is widely used in various fields, greatly changing people's production and lifestyle, and bringing convenience. Finally, the photos are given off as the electrons and holes are recombined. Secondly, electron and holes at the junction are combined. Pushing the holes in the opposite direction. From the diagram, we can observe that the N-type silicon is in red color and it contains the electrons, they are indicated by the black circles, while P-type silicon is in the blue color and it contains holes, they are indicated by the white circles.įirstly, the power supply across the p-n junction makes the diode forward biased, pushing the electrons from n-type to p-type. The above diagram shows how the light-emitting diode works and the step by step process of the diagram. The magnificent, beautiful, dazzling colors involved with LEDs may be quite picturesque, but do you really know how these effects are actually created in them or rather how LED works? Recent developments have produced high-output white light LEDs suitable for room and outdoor area lighting. Infrared LEDs are used in remote-control circuits, such as those used with a wide variety of consumer electronics.Įarly LEDs were often used as indicator lamps, replacing small incandescent bulbs, and in LED displays. Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared light. A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it.
