  • Publication number: 20230269969
    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 adjacent metal-containing overhang structures defining each sub-pixel of the sub-pixel circuit of the display provide for formation of the sub-pixel circuit using evaporation deposition and provide for the metal-containing overhang structures to remain in place after the sub-pixel circuit is formed (e.g., utilizing the methods of the fifth, sixth, or seventh exemplary embodiments). Evaporation deposition may be utilized for deposition of an OLED material and cathode. The metal-containing overhang structures define deposition angles, i.e., provide for a shadowing effect during evaporation deposition.
