A method for fabricating an organic light-emitting diode (OLED) connected to an organic thin film transistor (OTFT) on plastic substrates without heating is proposed. A three-dimensional pixel structure consisting of an OLED and an OTFT is prepared by the proposed method, and the characteristics of the device are tuned by refinement of structural parameters. By room-temperature fabrication, the OTFT with passivation film can be formed on a poly(ethylene naphthalate) plastic substrate, and the transparent anode of the OLED can be fabricated on the passivation film directly. OLED emission is thus generated directly by the current flowing through the OTFT, and the emission intensity is fully controllable by the gate voltage.
