On December 13, Professor of physics at KAIST Zhao Yongxun group and Samsung Electronics comprehensive technology College (Bell pray) jointly developed the 3 primary colors – red, green, blue, and it is difficult to make the fabrication of various tones such as white. The technology can be marked with a color on the screen at once, so if a business, be more distinct than the existing colors on the monitor.
Research Group of Professor Zhao is "gallium" produced only a few μ m (Micron, 1 million per 1 m) size of hexagonal pyramid pattern LED semiconductors. If you give the semiconductors on the phone, over voltages can appear different colors. Incline of the six corner kicks, corners, high light the color is different. Developed according to voltage size of various colors of technology. The research team also produce the semiconductor 300nm of smaller than this (nano, 1 one nanometer is equal to 1 billion meters) of semiconductors, has been successful. The findings, published in world-class academic journals in the field of materials science of the Sturt in the 1st issue covers on the thesis of Li Er diermosi.
Professor Zhao pointed out: "without using fluorescent substance produced various wavelengths (colors) of the fact that, for science industry is significant" and "business, if further additional studies, we can develop better products. "Korea LED the development of scientific and technical personnel preparation materials, Japan, and Germany to seize a new era of LED technology. Japan and Germany are also in the development of fluorescent substances are not used to represent various tones of LED technology. But was unable to train 3 inches above the size of the price is very expensive. Although there are different from LED AMOLED (organic light-emitting diode), but mainly used in smart phones and other mobile devices.
Take nazhao Professor group of research results of Korea electronic communications Institute next-generation LED research leader Quan Wujun said: "Japan of nijiya and Germany of Lammy, Enterprise monopoly has tones LED technology of related patent, Korea enterprise was close to limit", "the development of technology can with in TV and monitor as of large screen Shang, because and no using expensive of material so further reduced has production cost". Then he added: "as close to in different ways, there is no patent issues", "if doing a follow-up study, can be made thinner and cheaper than it is now the TV and monitor raw materials". Samsung LED stakeholders, says: "this is just the early stages of research and development, 5 years before they can implement practical
