We have developed a new nozzle coater that can fabricate walls or ribs with a high aspect ratio (the ratio between the height and width of a rib as seen in a cross section) on a substrate. The aspect ratio of these walls is a minimum of 15 to 20 and can be increased upwards, and has a width of 15 to 200 μm. Two of the features of this nozzle‐based coating machine are its special nozzle shape and the good UV hardness that is achieved soon after the material is dispensed. Ribs can be used as FED spacers. Each nozzle has multiple openings and the unit consists of multiple nozzles so that a substrate width of 42″ can be coated in a single scan. Using this method, spacers can easily be created on a substrate, at low cost. In addition, this method can be used for fabricating PDP ribs, especially when constructing bus electrodes for ELs.
