High-Performance Flexible TFT Circuits Using TIPS Pentacene and Polymer Blend on Plastic
TLDR
In this article, an 11-stage ring oscillator (RO) made of organic thin-film transistors (TFTs) exhibits the switching speed of 31.4 kHz at the supply voltage of 20 V.Abstract:
We report the high-performance circuit on 25-μm polyimide substrate with organic thin-film transistors (TFTs) (OTFTs) using 6,13-bis(triisopropyl-silylethynyl) pentacene and polymer blending. Because of high mobility (0.64 cm2/V·s) and low threshold voltage (<;|1 V|) of the TFTs, an 11-stage ring oscillator (RO) made of these TFTs exhibits the switching speed of 31.4 kHz at the supply voltage of 20 V. The output waveforms of the RO change little after 5000 times bending with a radius of curvature of 2 mm, and thus, the OTFT circuits can be applied to very flexible electronics.read more
