Overhang pattern for advanced OLED patterning

A device, comprising:

• a substrate;
• a plurality of overhang structures disposed over the substrate, each overhang structure having:
• a first structure, comprising:
• an upper surface;
• a lower surface;
• and
• a plane of a sidewall, wherein:
• the upper surface has a first width greater than a second width of the first structure at the plane;
• and
• the lower surface has a third width greater than the second width of the first structure at the plane;
• a second structure disposed over an upper surface of the first structure;
• and
• adjacent overhangs, each overhang defined by an overhang extension of the second structure extending laterally past an upper surface of the first structure;
• and
• a plurality of sub-pixels, each sub-pixel comprising:
• an anode;
• an organic light emitting diode (OLED) material disposed over the anode;
• and
• a cathode disposed over the OLED material.
