Tokyo, Japan – The price of organic electroluminescent looks set to fall after a research team based at the University of Tokyo revealed a method for making them more cheaply.
However, as with so many of these Japanese developments, practical applications are way down the line – it could be as long as five years before the method reaches volume manufacture.
OEL panels save energy, the colors are displayed faithfully and use organic materials that light up when current is applied. According to nikkei.net, the breakthrough made by professors Eihi Nakamura and Hayato Tsuji, have developed a new highly conductive organic material that could cut costs of manufacture by as much as 50 percent.
The prototype device the professors have created is tiny, according to nikkei.net, being only 2mm by 2mm square and 100-150mm thick. The prototype only has three layers, compared with current technology which can use as many as eight layers.
