Recently, GE's Global R&D Center announced that they have developed a solution-based organic coating material with Konica Minolta (KM) to complete the commercial application of OLED (Organic Light Emitting Diode). A foot on the door." Yesterday, the reporter learned from relevant parties that in Yangzhou, research and development projects related to organic light-emitting diode technology have started.
OLED technology is still in the experimental stage
Wang Haibo, director of the Institute of Electrical Light Source Materials at Nanjing University of Technology, said that as a new type of LED technology, OLED technology has attracted the attention of scientists around the world. Research and development of this technology is underway in relevant companies and laboratories. Unlike the current LED technology, OLED is a technology that is still in the laboratory, and it takes a long time to become a reality.
On the surface, LED and OLED are very close, and they are solid-state luminescence technology. Both use the principle of “electron-hole recombination†to illuminate. It is like a pair of “sisters†and “blood relationshipâ€, but the difference is quite big. . Experts said that the LED carrier's illuminating carrier, ie the chip, is made of semiconductor material; the OLED illuminating carrier is an organic material, and the two layers of electrodes sandwich the organic material film, which can emit light after being energized. The LED is a point source, so it can only be used as a backlight on the display. OLEDs are surface light sources that can be used directly to make displays. In the future, this technology will first be applied to the display and may also be used for lighting.
OLED is not far from Yangzhou
The relevant person in charge of the Municipal Science and Technology Bureau said that OLED is a new type of LED technology. LED cities like Yangzhou cannot be absent and must keep up with the development trend of the world.
In fact, Yangzhou enterprises have already touched such signals and have already started research and development. Recently, Yangnong Chemical has upgraded the research and development of new materials in the new round of transformation, including OLED technology. It is understood that the laboratory products of this project have been developed and are entering the trial phase. Through the integration with related component manufacturers, the future will be expected to lead Yangzhou's OLED technology.
According to relevant sources, displays using OLED technology are thinner, more colorful, and have no visual dead angles than traditional LED displays. At present, Nokia, Sony and other branded mobile phones are trying to use OLED technology in mobile phone displays.
Industrialization still needs time to cultivate
OLED has so many advantages, does it mean that it will become an upgraded version of LED? The attitude of the industry is still cautious, and now many technologies are still in the experimental stage, for commercial applications, mass production must overcome many difficulties, so that Laboratory products have become mass consumer goods.
Faced with the optimistic attitude of experts on OLED, the person in charge of the local tablet company in Yangzhou said that this new product, whether it is used on our computers, also needs to solve the OLED technology matching and price problems. After all, it is a new product and the price will be higher.
Experts said that OLED as an emerging lighting technology, Yangzhou needs to continue to follow up, which is also the need for the development of this LED city in Yangzhou. However, in terms of large-scale application promotion, the main focus is still on LED. In any case, the future lighting market cannot be “out of the boxâ€, the more technically it is, the more consumers choose, and OLED is also a consumer choice.
