Low-Temperature, Sustainable Manufacturing of Printed OTFT Backplanes for Electrophoretic and OLED Displays.

ABSTRACT: Printed electronics have garnered significant attention for developing lightweight, cost-effective, and environmentally friendly systems, driving significant advancements in the realm of sustainable electronics. This study introduces a printed active-matrix organic thin-film transistor (OTFT) backplane, fabricated under ambient conditions using low-temperature printing and solution-based processes. All electrode layers-including gate, source/drain, and pixel electrodes-are patterned through reverse-offset printing (ROP), achieving high-resolution multilayer integration with minimum line widths of 10 µm. The resulting OTFTs demonstrate robust performance in ambient air, achieving a carrier mobility of 1.12 cm² Vs^-1 and on/off ratios exceeding 10⁸. The printed backplane
