OLED

The success of today's digital electronics is based on the CMOS technology.

University of Utah, physicists have moved a step forward in building an organic "spin transistor": a plastic semiconductor switch for future ultrafast computers and electronics but OLED efficiencies look bleak.

Although OLED technology is still developing there is currently a notable market presence of OLEDs in electronic devices and displays.

The largest potential market for OLEDs is for mass produced, flexible, low cost versions, particularly wide area types with long life because they enable many exciting new product concepts to be realised rather than replace existing displays in familiar devices.

Innovative design is used to achieve superior solar conversion without optical tracking.

Printed electronics today is mainly a matter of inorganic rather than organic chemistry and the next ten years are unlikely to see the inorganic part drop below 50% of the high value materials required.

At the end of the project period, the OLLA project consortium presents its final milestone: the basic technology for a white OLED (Organic Light-Emitting Diode) light source, with an efficacy of 50.7 lumens per watt at an initial brightness of 1.000 cd/m² based on the Novaled PIN OLED technology. The OLLA project is a joint basic research consortium, headed by Philips Lighting.
