Abstract
This research paper analyzes a two transistor active matrix organic light emitting diode (OLED) display using vertical channel OTFT as access and driver transistors. The driver V-OTFT has high on-off ratio and enhances the circuit performance. The OLED used is a single layer, back-emitting OLED, utilizing Poly (p-phenylene vinylene), PPV as organic semiconductor layer. OLED are better than ordinary LEDs and LCD (Liquid Crystal display) in terms of viewing angle and flexibility. The transient and DC response of the circuit are analyzed. A current of about 4 µA flows through the OLED, when switched on, at moderate operating voltage. The display utilizes only organic components and is hence flexible and finds use in large area roll-able displays.
