METHODS OF FABRICATING OLED PANEL WITH INORGANIC PIXEL ENCAPSULATING BARRIER

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 device includes a plurality of sub-pixels, each sub-pixel of the plurality of sub-pixels defined by adjacent pixel-defining layer (pdl) structures with inorganic overhang structures disposed on the pdl structures, each sub-pixel having an anode, organic light-emitting diode (oled) material disposed on the anode, and a cathode disposed on the oled material. the device is made by a process including the steps of: depositing the oled material and the cathode by evaporation deposition, and depositing an encapsulation layer disposed over the cathode.
