Abstract
Embodiments described herein relate to a device comprising a substrate, a pixel-defining layer (PDL) structures disposed over the substrate and defining sub-pixels of the device, and a plurality overhang structures. Each overhang structure is defined by a top structure extending laterally past a body structure. Each body structure is disposed over an upper surface of each PDL structure. Overhang structures define a plurality of sub-pixels including a first sub-pixel and a second sub-pixel. Each sub-pixel includes an anode, an organic light-emitting diode (OLED) material, a cathode, and an encapsulation layer. The OLED materials are disposed over the first anode and extends under the overhang structures. The cathodes are disposed over the OLED materials and under the overhang structures. The encapsulation layers are disposed over the first cathode. The first encapsulation layer has a first thickness and the second encapsulation layer has a second thickness different from the first thickness.
