Abstract
Methods and OLED devices are provided in which organic emissive materials are deposited over a substrate via OVJP print heads in a continuous line extending from one edge of the active display portion of a substrate to another. The print heads are arranged such that the sidewalls of the OVJP jet are disposed over non-emissive insulating portions of the display panel, thereby allowing for improved pixel density and resolution in comparison to conventional OVJP and similar techniques.
