MAY 19--CRL Opto Ltd. (Hayes, Middlesex, UK; www.crlopto.com), a supplier of microdisplays, has been selected to lead a consortium to develop novel photopatternable light-emitting polymer OLED-on-silicon displays. Consortium members include Thomson (www.thomson.net), the French Atomic Energy Commission (CEA; www.cea.fr), DSM Desotech (Elgin, IL; www.dsmdesotech.com), and the University of Hull (www.organophotonics.co.uk). The collaborative project is called PhotoLEDD and is supported by the European Commission.
The primary aim of this project is to demonstrate that the economic manufacture of both 2-D and 3-D direct vies and miniature OLED displays can be made through the development of photopatternable organic light-emitting diodes (p-OLEDs) RGB emitter materials and related manufacturing processes. The photopatternability of the new p-OLED materials is expected to allow the conventional photolithography techniques to be employed so that high-resolution color displays can be manufactured using fewer processing steps than used by color filter-based matrix displays. Color will be generated by a color conversion technique based on a blue emitter.
The development of the new stereoscopic 3-D displays will use a concept jointly patented by CRL Opto and Hull University based on the emission of polarized light from an OLED device.
