         Shenzhen Risen OPTO Co.,Ltd,led flood light supplier,Aluminum Alloy Flood Light Manufacturers,waterproof led lamps supplier china.White is a rising star in lighting technology, the US Department of Energy (DOE) forecast in 2020, the cost of OLED lighting efficiency and lifetime of the LED indicators will be no distinction of any kind!

        But now industry has encountered difficulties life is too short for organic light-emitting blue phosphor material. OLED light-emitting layer is mainly composed of red fluorescent material, green and blue phosphor material material three mixed into white light, in which the life of a material decay, it will make whole pieces OLED failure, how to overcome the material life varies, a challenge to the industry problem.

        Taiwan ITRI R & D "OLED surface plasmonic coupling gain technology", the green light-emitting material is converted to the blue spectrum, blue light-emitting organic material break through the bottleneck of life is too short.

        Taiwan ITRI "Blu-ray is now a" solution of the road, which is not to use any blue material, but the technology to make the green material into the blue source, in order to develop the OLED surface plasma coupling gain technical PCOLED (Plasmon-Coupled Organic LED).

         ITRI is Taiwan had during the experimental green light emitting structure material, green material found impossible actually issued a blue light, so that the institute opened a new research direction, and later by physical thinking, design green materials special structure, and constantly adjust the parameters, and finally to identify and summarize the reasons for and methods of the original green material emitting blue light

         Finally DML produce planar type plasma coupling structure effect (Plasmon-Coupled), capable of emitting green material spectrum is converted to blue, white OLED will be able to use green materials to replace the traditional blue material layer, not only the problem of life is too short solved, even more than the traditional OLED extended up to 20 times.

         In terms of efficiency, through continuous development and component optimization, DML blue light-emitting efficiency has been able to go beyond the existing level of the blue fluorescent material and most of the known blue phosphorescent material can be achieved by 35cd / A. White OLED DML technology has been validated, may issue a color rendering (CRI) of 77, a color temperature of 2039 K white light, can be used as an indoor lighting use, and the institute has successfully lit 10 cmx10 cm large white modules.

         ITRI team now has the relevant technical application on to Taiwan, Germany, the United States and China patents, and has worked with civil industry, to further understand the key OLED materials and process technology to the industry
