OLED firm UDC has said there is no row between it and UK organic LED company CDT 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.”
