2015 LED related new technology and new application information summary


2015 has become history and 2016 has arrived. In the past period of time, the author has comprehensively counted some LED- related new technologies and new application information around the world, and hopes to provide an overview of the progress of LED technology and the channels for extracting application creative nutrients. We always believe that LED will release unlimited potential in the future.

"Zero-defect" new semiconductor materials

It is said that the thinner the semiconductor material, its physical defects, will have a negative impact on the usable performance of electronic and optoelectronic components. The multinational research team consisting of Li Yan, the president of the front desk, and He Zhihao, who was a professor at the National Taiwan University of Electronics, has recently announced that he has found a way to repair defects and successfully developed new semiconductor materials with “zero defects”. According to reports, this team constructed a high-quality single-layer two-dimensional semiconductor material MoS2, which avoids the problem of excessive defect density of two-dimensional materials in the past, and is expected to greatly improve the luminous efficiency of LED , and has the opportunity to become an important material in ultra-small semiconductor components. Choose one.

The research team said, can develop high performance materials which led both transparent flexible display, and ultra-efficient solar power generators, high sensitivity photodetector element, as well as lower power nm Class semiconductor transistor components. They infiltrated the molybdenum disulfide (MoS2) material into the organic super acid of the bistriflimide, which greatly improved the quantum efficiency of the two-dimensional material, which can be increased from the original increase of less than 1% to nearly 100%. Multiplier effect. Therefore, although this material is still expected to be commercialized for some time, it is undoubtedly worthy of the world's expectations.

Turn the ceiling into a lighting system

Recently, Apple announced a new patent unrelated to electronic digital devices. This patent is related to Apple's AppleStore retail store ceiling lighting system. In this patent, Apple's design abandoned the single light source currently used, and designed the entire ceiling into a lighting system. They are spliced ​​into different patterns with ceiling panels and narrow slots with or without illumination. Wherein led lamp tubes or other light sources of the illumination function mounted panel, direct down by a plastic diffuser, or a reflective back down through the material. In addition, electronic systems such as cameras, microphones, alarms, and fire alarms can be integrated into the ceiling.

Apple said that the entire ceiling is designed as a lighting system to provide a more consistent lighting environment for customers entering the store to provide a more ideal experience. The use of this lighting system in the AppleStore retail store, in addition to helping to improve the customer's product experience, also provides more possibilities for the store's product display layout. Today, the system has been initially applied to some Apple retail stores, including the Apple Store in Brussels. According to reports, in the future it will be pushed to the storefronts worldwide.
