Amoled TFP Pixel Circuitry for Flexible Displays on Metal Foils

摘要

Active matrix organic light emitting diode displays based on thin,flexible metal foil substrates offer a novel approach to fabricate light,flexible and rugged displays.Metal foils allows devices to be fabricated at higher process temperatures yielding better device characteristics than plastic substrates.Furthermore,the conductive nature of such substrates enables more efficient use of pixel area through the use of a global power electrode.We are implementing Active Matrix Organic Light Emitting Diode (AMOLED) displays on flexible stainless steel substrate using 2 TFT and 4 TFT pixel circuit topologies with two different layout realization that exploit the conductive properties of the substrate.
