An organic integrated pixel with organic light-emitting diodes (OLEDs) driven by organic thin film transistors (OTFTs) is fabricated by a greatly simplified processing.The OTFTs are based on copper phthaJocyanine as the active medium and fabricated on indium-tin-oxide (ITO) glass with top-gate structure,thus an organic integrated pixel is easily made by integrating OLED with OTFT.The OTFTs show field-effect mobility of 0.4cm2/Vs and on/off ratio of 103 order.The OLED is driven well and emits the brightness as large as 2100cd/m2 at a current density of 14.6 μA/cm2 at-19.7 V gate voltage.This simple device structure is promising in the future large-area flexible OLED displays.
