Abstract
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. The sub-pixel circuit includes a plurality of contact overhangs. The plurality of contact overhangs are disposed between adjacent sub-pixels of a sub-pixel circuit to be formed. The contact overhangs are formed over a metal grid exposed through a PDL structure. A cathode is deposited via evaporation deposition to be in contact with the contact overhang. The metal grid is perpendicular to a plurality of metal layers disposed on the substrate.
