Japan Display has been developing technology for mass production of OLED panels since 2014 on an experimental line designed to handle small glass substrates. The new full-scale production line will employ a process called vapor deposition, in which the light-emitting material is applied as a vapor in a vacuum.
Japan Display has also reached a technology development agreement with Semiconductor Energy Laboratory Co., Ltd. (SEL) regarding the development of backplane technology for next-generation displays, including organic light emitting diode displays.JDI, in addition to its LTPS and other proprietary technologies, is now able to leverage SEL resources for oxide semiconductor technology in order to develop display products.
Samsung Display, which supplied the OLED displays for Samsung's Galaxy series of smartphones in 2010, has been the leader in the OLED production.
Apple plams to use OLED screens in iPhones from 2017 onward. LG Display, Sharp and other major panel manufacturers are increasing research and investment in production capacity in the OLED field.
