Fully transparent conformal organic thin-film transistor array and its application as LED front driving

Abstract

Fully transparent conformal organic thin-film field-effect transistor array is demonstrated based on the photolithography-compatible ultrathin metallic grid gate electrode and the solution-processed C8-BTBT film. The resulting organic field-effect transistor array exhibits high optical transparency of >80% over the visible spectrum, mobility up to 2 cm2 V-1 s-1, on/off ratio of 105-106, switching current of >0.1 mA, and excellent light stability. The transparent conformal transistor array is demonstrated to well adhere onto the flat and curved LEDs as front driving. These results present promising applications of the solution-processed wide-bandgap organic semiconductor thin films in future large-scale transparent conformal active-matrix displays.
