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.
