Claim:
1. An organic optoelectronic device (OED), comprising: a substrate having an OED cell support surface; an OED cell located at an OED cell area along the support surface, the OED cell including a layer of vapor printed small-molecule organic material arranged between first and second electrodes; and a vapor flow barrier extending away from the support surface alongside the OED cell and arranged to contain the small-molecule organic material within the OED cell area, wherein the layer of vapor printed small-molecule organic material is deposited with a combination of processing conditions over the OED cell area along one side of the vapor flow barrier via a jet of gas directed toward the support surface from a vapor printing nozzle, the jet of gas comprising the small-molecule organic material, and wherein the vapor flow barrier extends away from the support surface to a height that is sufficiently large to prevent the small-molecule organic material from being deposited over the support surface at an opposite side of the vapor flow barrier at the combination of processing conditions.
