55.2: Ink-Jet Printed AMOLED Displays Based on High Mobility IGZO TFTs: Cost Does Matter

AMOLED displays based on metal oxide film as active channel layer are fabricated. To achieve cost‐competitive process in OLED manufacturing, solution‐processed HIL, HTL and pixilated EML (RGB) layers followed by evaporation process for other layers are demonstrated in this work. Meanwhile, the AMOLE...

Description
Summary:AMOLED displays based on metal oxide film as active channel layer are fabricated. To achieve cost‐competitive process in OLED manufacturing, solution‐processed HIL, HTL and pixilated EML (RGB) layers followed by evaporation process for other layers are demonstrated in this work. Meanwhile, the AMOLED backplanes possessing low power consumption and high frequency were fabricated on metal oxide TFTs with high mobility (23.13 cm2/Vs) technology. A 14” qHD AMOLED in 79 ppi‐resolution was realized with IGZO based active matrix panel.
