Abstract
A method of depositing a cathode on an organic light emitting diode (OLED) stack is provided. The method includes providing a substrate having at least a partial organic light emitting diode (OLED) stack disposed on a surface of the substrate. The method further includes depositing, on top of the partial OLED stack, a solution comprising a metal compound. The method further includes forming a conductive solid layer from the metal compound in the solution to form a cathode for the partial OLED stack.
