Epson’s OLED TV Printing Technology

– TOKYO, Japan, May 26, 2009 –

Seiko Epson Corporation today announced it has established inkjet technology that enables the uniform deposition of organic material in the production of large-screen organic light-emitting diode (OLED) televisions. The new technology represents a major step toward the realization of 37-inch and larger full-HD OLED TVs by resolving the uneven layering that had previously been an issue with the inkjet method.

OLED televisions are the odds-on favorite to supplant current technologies as the next generation display. Offering outstanding viewing characteristics, including high contrast, wide viewing angle and fast response time, OLED TVs are also lightweight, ultra-thin, and have low power requirements. A major roadblock preventing mass production of large-screen OLED TVs has been the lack of a technology capable of reliably forming uniform organic layers on large substrates. Vacuum thermal evaporation (VTE), currently the most widely used method of depositing organic materials, is surrounded by technical hurdles that have prevented it from solving the layer uniformity issue and making the jump to mass production of large panels. An inkjet process that deposits organic material in liquid form has long been viewed as the ideal alternative.
