摘要：

In order to demonstrate the possible application of an organic thin film transistor (OTFT) to a flexible active matrix organic light emitting diode (OLED) an array of 64 x 64 pixels was fabricated on a 4-in. size poly-ethylene-terephehalate substrate. Each pixel was composed of one OTFT integrated with one OLED. OTFTs successfully drove OLEDs by varying current in a wide range and some images were displayed on the array by emitting green light. The OTFTs used poly(4-vinylphenol) for the gate and pentacene for the semiconductor taking account compatibility with the PET substrate. The average mobility in the array was 0.2 cm(2)/V center dot s, which was reduced from 1.0 cm(2)/V center dot s in a single OTFT, and its variation over the entire substrate was 10%.
