Abstract:
Sub-pixel circuits and methods of forming sub-pixel circuits that may be utilized in an organic light-emitting diode (OLED) display are described herein. The overhang structures are permanent to the sub-pixel circuit. The overhang structures include a conductive oxide. A first configuration of the overhang structures includes a base portion and a top portion with the top portion disposed on the base portion. In a first sub-configuration, the base portion includes the conductive oxide of at least one of a TCO material or a TMO material. In a second sub-configuration, the base portion includes a metal alloy material and the conductive oxide of a metal oxide surface. A second configuration of the overhang structures includes the base portion and the top portion with a body portion disposed between the base portion and the top portion. The body portion includes the metal alloy body and the metal oxide surface.
