| Resumo: | We present a novel integration process of all organic Thin Film Transistor (TFTs) and its electrical characterization. The test circuit is designed to drive an active matrix of organic light emitting diode (AMOLED). The process is performed in both plastic (Polyethylene naphthalene, PEN) and glass substrates. The basic circuit is formed by two pentacene-based transistors and a capacitor. All of these devices use parylene as dielectric. As a result of the electrical characterization, we show that this circuit can deliver up to 40 π A. This current level is appropriate if we consider that the minimum required current to obtain 200 cd/m 2 from a typical OLED is of 10 π A. |
