Universal Display says there is no row between it and UK organic LED company Cambridge Display Technology following a patent UDC revealed recently. The patent is primarily about the ability to ink-jet print OLEDs using small molecular materials, instead of polymeric materials, for light emission, Janice Mahon, v-p of technology commercialisation at US-based UDC told Electronics Weekly. CDT’s patents largely cover polymeric emissive materials and it is unlikely the patent will cause a conflict.
However, while UDC’s technology in this new patent is fundamentally small-molecule and not polymer, UDC’s patent portfolio broadly covers phosphorescent OLED technology, said UDC’s Mahon. It is too early to tell what structures will be commercialised. We have a very important phosphorescent portfolio just as CDT has a very important polymer portfolio, said Mahon. Mahon added: The competition is LCD, it is not polymer versus small molecule.
