We demonstrate the integration of organic light-emitting diodes (OLEDs) and thin film transistors (TFTs) on 25 μm thick, highly flexible stainless steel substrates. Our goal is to develop an active matrix OLED display that can be folded for use in highly rugged and portable applications such as foldable intelligent maps. OLED/TFT structures were fabricated on 38 mm×38 mm steel foils and subsequently scissor-cut into strips 4 mm wide and 38 mm long. These strips were rolled along their length and tested for topological integrity and electrical/optical performance. The transistors remain operational under convex or concave bending down to 2.5 mm radius of curvature. Our results suggest that foldable displays are feasible.
