The integration of the top-emitting organic light-emitting diode (OLED) driven by the organic thin film transistor (OTFT) was investigated. The OTFT operating voltage is decreased
via
reducing the thickness of the gate insulator layer. OLED adopts standard devices structure with green emission and employs the thin Al film as transparent cathode to realize top-emission. The integration of low-voltage operation OTFT and top-emitting OLED is achieved
while the threshold voltage of the OTFT is 2.0 V and the saturation field effect mobility is 0.40 cm
