The world's thinnest flexible full-color 5.6-in. active-matrix organic-light-emitting-diode (AMOLED) display with a top-emission mode on stainless-steel foil was demonstrated. The stress in the stainless-steel foil during the thermal process was investigated to minimize substrate bending. The p-channel poly-Si TFTs on stainless-steel foil exhibited a field-effect mobility of 71.2 cm(2)/V-sec, threshold voltage of -2.7 V, off current of 6.7 x 10(13) A/mu m, and a subthreshold slope of 0.63 V/dec. These TFT performances made it possible to integrate a scan driver circuit on the panel. A top-emission EL structure was used as the display element, and thin-film encapsulation was performed to realize a thin and flexible display. The full-color flexible AMOLED display on stainless-steel foil is promising for mobile applications because of its thin, light, rugged, and flexible properties.
