Invisible Ag-grid transparent electrodes have been printed on a flexible epoxy film. The Ag-grid electrode were laminated with a poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) layer. The electrode shows no noticeable resistance change throughout the bending cycles at a bending radius of 1.0 mm. The transparent electrode-based powder electroluminescent device develops excellent flexibility.
