In this regard, the Nichia Chemical Industry, said the future will be to promote the "standard LED" production preparation. Japan's Industrial Research Institute, said it will further improve the "standard LED" in the development of the spectrum used in precision measurement technology, research and development of surface light source and ultraviolet and infrared light range of light evaluation technology.


A single layered LED produces a single pixel of white light
Production of white LED, not the use of white phosphor (phosphor) coated material coated monochrome LED, is the red, green and blue LED mixed together? Researchers at the University of Taiwan do not think so, they are developing a technology, from a single tiered-column (tiered-column) LED produce a single pixel (pix) of white light. The basic concept is that quantum wells are grown on the same substrate, and very tightly aligned GaN and In-GaN nanowires are embedded in the same substrate.

According to the researchers pointed out that the LED array is the organic metal chemical vapor deposition (MOCVD) pulse growth method, can achieve better than using the traditional process technology luminescence performance. They have developed multi-section nanorods of different cross-sectional dimensions that can exhibit a broader emission spectrum than single-column nanoplasts. The goal of this multi-section nanocolumnar LED is to emit Out of the phosphor-free white light. At the same time, the team is also working on surface plasmonics to enhance luminescence, improve efficiency and avoid droope effects, and speed up visible-light high-speed communications with increased bandwidth modulation.

Apple VR head display or will use micro-LED display
Last May, Apple acquired the mini LED display technology leader in the industry LuxVue, the outside world is generally considered LuxVue will achieve a breakthrough on the display technology. Apple will use this technology has become a public talk about the topic, but to the present position has no clue. Apple had previously announced 2017 of the iPhone mobile phone screen supply chain will be replaced by OLED, AppleWatch's screen has been replaced by OLED. Micro-LED display in the territory of the Apple Empire where, no doubt even more confusing.

It is speculated that the micro-LED technology is likely to be used for "direct-type display", including applications in augmented reality and virtual reality, such as the first display. EXALOS CEO said that for the next generation of display, micro-LED will be to improve the performance and brightness of the key components. LED micro-display is ideal for use in wearable system, because the LED mini-display has a small space, low power consumption, high contrast and high brightness characteristics. Although the current direction of this advanced technology into fans, but in the near future, will appear in some consumer and professional version of the body.


Ski suits with 7000 Philips LED decorative lights
In a recent video, a team of skiers dressed in 7000 LED lights decorated clothing, from the color spotlights down the ramp down, it was directed at, which is high-tech lighting to the skiing of the gorgeous. It is reported that this 12-minute micro-film shooting in British Columbia and Alaska Golden Alps resort. In order to illuminate the entire mountain slope, the staff used eight 4000-watt headlights and other small lights. Using UAVs and fixed cameras to take pictures of skiers from the slope down the scene.

In fact, this is a micro film to promote Philips Ambilight television. Among them, the ski suit on each piece of Gore Stores fabrics are sewn thousands of LED lights, this fabric is waterproof material and connected to the candy-sized battery. The film took five weeks, costing £ 9,000, at minus 15 degrees Fahrenheit. Although the cost is not small, but Philips hopes in this way to promote its overflowing color television lighting technology superiority, and to show the world how to completely change the human experience.


Silicon substrate project won the National Technology Invention Award
It is understood that the current international LED lighting technology on a total of three routes: sapphire substrate, silicon carbide substrate and silicon substrate GaN-based LED technology (that is, "silicon substrate LED technology") route. Which the first two routes in the industry in turn known as the mainstream technology route and the "noble" line, the core invention patents were the United States and Japan were monopolized. Silicon substrate LED technology is the birth of the meaning of another new path, so that China has the world's third LED lighting technology line, a new light source to break through the barriers to get rid of patent disputes.

In the preparation of high-efficiency gan-based LED on the silicon, has been the goal of academic efforts. However, due to the large lattice mismatch and thermal mismatch between GaN and GaAs, the problem of epitaxial film cracking, poor crystal quality, and poor light extraction efficiency due to substrate opacity has not been solved for a long time. Almost sentenced to death. In fact, as early as 30 years ago, IBM Corporation in the development of silicon substrate LED technology, but "give up halfway" to give up. Chinese researchers in this situation is the technology "picked up." After thousands of experiments, continuous technical research, since 2003, the R & D team has finally made a breakthrough, which has developed a silicon substrate GaN-based LED materials and device technology.
