We report the integration of organic light emitting devices (OLED's) and amorphous Si (a-Si) thin-film transistors (TFT's) on both glass, and unbreakable and lightweight thin stainless steel foil substrates. The doped-polymer OLED's were built following fabrication of driver TFT's in a stacked structure. Due to the opacity of the steel substrate, top-emitting OLED structures were developed. It is shown that the a-Si TFT's provide adequate current levels to drive the OLED's at video brightness (∼100 cd/m2). This work demonstrates that lightweight and rugged TFT backplanes with integrated OLED's are essential elements for robust and highly portable active-matrix emissive flat-panel displays.
