Schematic diagrams of top-emitting polymer OLED with a configuration of: (a) glass/Ag/ITO/PEDOT/Ph-PPV/semitransparent cathode, (b) Al-PET/acrylic layer/Ag/ITO/PEDOT/Ph-PPV/semitransparent cathode, and (c) cathode.
AFM images measured for a typical Al-PET substrate without (a) and with (b) an acrylic layer.
(a) and (b) characteristics of three devices with a configuration of cathode (closed circles), cathode (open circles), and cathode (open diamonds).
(a) Luminous efficiency of two top-emitting OLEDs with aconfiguration of /semitransparent cathode (closed circles), and /semitransparent cathode (open diamonds). (b) A photo image showing a flexible top-emitting electroluminescent device on Al-PET substrate.
