OLED sub‑pixel circuit with protective passivation material

Abstract

Embodiments described herein generally relate to a display. More specifically, embodiments described herein relate to sub-pixel circuits and methods of forming sub-pixel circuits that may be utilized in a display such as an organic light-emitting diode (OLED) display. In one or more embodiments, a sub-pixel circuit includes at least two anodes disposed over a substrate. A pixel-isolation structure (PIS) is disposed between the anodes. An overhang structure is disposed over the PIS. A protective layer is disposed between the PIS and the overhang structure. The protective layer extends over a portion of an upper surface of the anodes.
