Sumitomo research and development of printed OLED panel production technology

Japan Sumitomo chemical (Sumitomo Chemical Co.) issued a press release announced that has developed using inkjet method (printing) the production of polymer OLED panel technology, the technology can produce OLED panel resolutions up to 423ppi (using 370x470mm glass substrate size), the resolution is close to the evaporation evaporation (production technology red green and blue organic material on the glass substrate) "OLED panel production.

The chemical Sumitomo pointed out that by "printing technology" OLED material can be coated only where necessary, so in addition to production of OLED panels available low cost, large size can also apply to the panel, and the company will continue to improve the performance of polymer OLED materials, and process improvements, in order to polymer the OLED panel production contribute.

Sony, Panasonic announced in June 25, 2012, will be jointly developed for TV / LCD of the next generation OLED panel, and the two sides will jointly develop the "printed" the next generation of OLED technology is suitable for low-cost mass production of large size and high precision OLED panel technology.

It is understood that the production technology, the establishment of Panasonic once Sony "printed" OLED panel, then the current available LCD panel (LCD) about half the cost of production of large size OLED panel, and the use of printing technology will be easy to form an organic material film on the plastic film substrate, which is expected to produce a flexible (flexible) OLED panel.
