Abstract

Sumitomo Chemical has developed a new blue light-emitting material for polymer light emitting diodes (PLED). The material has also achieved a chromaticity and the 10,000-hour service life level necessary for commercial use. Compared to organic LEDs, PLEDs require a much simpler production process because they are easily applied to flat panel displays by printing, slashing manufacturing costs. This coupled with low energy use, self-luminance that eliminates the need for a backlight, make PLEDs a major future display element. The biggest hurdle to date has been PLED life, at only a few thousand hours. This is a short news story only. Visit www.three-fives.com for the latest advanced semiconductor industry news.
