    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.

    Abstract: Embodiments described herein generally relate to sub-pixel circuits that may be utilized in a display such as an organic light-emitting diode (OLED) display. The device includes substrate, pixel-defining layer (PDL) structures disposed over the section of the substrate, inorganic or metal overhang structures disposed on an upper surface of the PDL structures, and a plurality of sub-pixels. The PDL structures include a trench disposed in the top surface of the PDL structure. Each sub-pixel includes an anode, an OLED material disposed over and in contact with the anode, and a cathode disposed over the OLED material. The inorganic or metal overhang structures have an overhang extension that extends laterally over the trench. An encapsulation layer is disposed over the cathode and extends under at least a portion of the inorganic or metal overhang structures and along a top surface of the PDL structures.

    Abstract: Embodiments described herein relate to a device including a substrate, a plurality of adjacent pixel-defining layer (PDL) structures disposed over the substrate, and a plurality of sub-pixels. Each sub-pixel includes adjacent first overhangs, adjacent second overhangs, an anode, a hole injection layer (HIL) material, an additional organic light emitting diode (OLED) material, and a cathode. Each first overhang is defined by a body structure disposed on and extending laterally past a base structure disposed on the PDL structure. Each second overhang is defined by a top structure disposed on and extending laterally past the body structure. The HIL material is disposed over and in contact with the anode and disposed under the adjacent first overhangs. The additional OLED material is disposed on the HIL material and extends under the first overhang.
