Universal Display recently announced that it is accelerating OVJP R&D, and the company is looking to commercialize this technology with partners. UDC expects it to take a few years before OVJP can really be deployed in production. The company published the video below that shows off the technology and explains the basic principles and advantages.

OVJP stands for Organic Vapor Jet Printing, and the basic idea is to use a gas-stream based process that resembles ink-jet printing but one that uses evaporation OLED materials which outperform soluble ones. In an OVJP process, the OLED materials are evaporated into a carrier gas that delivers them to a jet engine for direct printing of patterned OLED layers. OVJP is intended for large-area OLED displays and can be scaled up to 10-Gen substrates according to UDC.

OVJP is a "mask-less deposition technology" which enables direct-printing of RGB direct-emission displays. UDC hopes that OVJP will enable a low cost, high performance, large area patterned OLED manufacturing process platform. UDC installed an OVJP prototype tool in its Ewing, New Jersey facility.




With the very rapid progress of IJP OLED, is this not too little too late? Wouldn't UDC be better served reopening their printed OLED project?
