13.5-inch Quad-FHD Top-Emission OLED Display Using Crystalline-OS-FET.

We have fabricated a 13.5-inch top-emission OLED display including an oxide semiconductor FET element. This display has a high pixel density exceeding 300 dpi and is applicable to a Quad-HDTV (number of pixels: 3840 × RGB × 2160). There have been few reports on fabrication of OLED displays with such a high pixel density so far. Color display is achieved by combining an EL element having a tandem structure and emitting white light with a microcavity structure and a color filter. [ABSTRACT FROM AUTHOR]
