High resolution organic light-emitting diode devices, displays, and related methods
Abstract:
A method of manufacturing an organic-light emitting diode (OLED) display can include providing on a substrate a first electrode associated with a first sub-pixel and a second electrode associated with a second sub-pixel, wherein a gap is formed between the first electrode and the second electrode and wherein the first electrode and the second electrode are positioned in a well having boundaries defined by a confinement structure on the substrate. The method can also include depositing in the well with the electrodes positioned therein, active OLED material to form a substantially continuous layer of active OLED material that spans the boundaries of the well such that a surface of the layer of active OLED material that faces away from the substrate has a non-planar topography. The depositing can be via inkjet printing.
