The development of new technologies to develop a variety of colors LED

In December 13th, the Department of physics professor KAIST Zhao Yongxun group and Samsung Advanced Institute of Technology (bell for common development) there are 3 basic colors: red, green, blue and white hard technology to produce various shades of production. The technology can immediately color on the screen, so if commercial, it will be more vivid than the existing monitor color.

Professor Zhao research group is the use of gallium produced only a few mu m (micron, 100 meters in the size of the size of the) of hexagonal Pyramid semiconductor LED. If the semiconductor is powered on, the voltage will appear in a variety of colors. Six the corners of the corners, edges and corners, the color of the high points are different. The development of a variety of colors according to the size of the voltage technology. The group also produced a smaller size than that of semiconductor 300nm (nano, 1 nanometer is 1 billion of a meter) following the semiconductor, has also been successful. The results of the study published a world-class academic journal "in the field of materials science, in the Diermosi Li Er" 1 journal papers cover.

Professor Zhao pointed out: "without the use of fluorescent material to produce various wavelength (color) the fact that the great significance of" science and industry "enterprise, if further additional research, will be able to develop better products. "Korea Science and technology personnel for the development of the LED material, a new era of LED technology to deal with Japan and Germany to seize the. Japan and Germany are also developing LED technologies that do not use fluorescent substances to represent a variety of tones. But it can't be more than 3 inches in size. Although there are different AMOLED (LED), but mainly used in smart phones and other mobile devices.

The research group of Professor Zhao Na of Korea Electronics and Telecommunications Research Institute a new generation of study leader LED said: "all right five of Japan's Nicky and Germany's Rahm enterprises monopoly patent hue LED technology, South Korea enterprises have been close to the limit", "the development of the technology can be used in large screen TV and like the monitor, because there is no use of expensive materials so as to further reduce the cost of production". Then he said: "because the approach is different, so there will not be a patent problem," if you do a follow-up study, you can make a thinner and cheaper than the current TV and display materials". Samsung LED stakeholders also said: this research is only the initial stage of research and development, 5 years after the realization of practical".
