Development of new inkjet technology for OLED display fabrication process by Seiko Epson
OLED televisions are considered as the next generation of display but in spite of their outstanding viewing characteristics such as high contrast, wide viewing angle, fast response time plus their light weight, ultra-thinness and low power consumption, the mass production of large screen OLED TVs has been hampered by lack of a technology capable of reliably forming uniform organic layers on large substrates limiting their application to small screen Laptop PCs and mobile phone screens as well other mobile devices with screen. Up to now, the method for depositing organic materials has been Vacuum thermal evaporation (VTE), but this method has an inherent technical difficulty in overcoming layer uniformity issue making it difficult to start a mass production of large OLED panels.
