摘要： An organic optoelectronic device (OED) includes a plurality of OED cells separated by a vapor flow barrier that extends away from a substrate surface. The vapor flow barrier partially defines an OED cell area and helps prevent stray organic material deflected away from the substrate surface during deposition from being deposited outside the cell area. An organic vapor jet (OVJ) print head can be used to deposit organic material along the vapor flow barrier and may include one or more features configured to capture some of the stray organic material. A method that includes use of vapor flow barriers and/or capturing stray organic material can facilitate high-density printing of OED cells such as OLEDs with sharply defined edges and without cross-contamination among adjacent cells.
