Abstract: Methods of fabricating a device having laterally patterned first and second sub-devices, such as subpixels of an OLED, are provided. Exemplary methods may include depositing via organic vapor jet printing (OVJP) a first organic layer of the first sub-device and a first organic layer of the second sub-device. The first organic layer of the first sub-device and the first organic layer of the second sub-device are both the same type of layer, but have different thicknesses. The type of layer is selected from an ETL, an HTL, an HIL, a space and a capping layer.

Abstract: Disclosed is a novel moisture permeation barrier system for substrates and devices and method of making the same. The permeation barrier system includes two barrier layers. The first barrier layer is disposed over the substrate or an electronic device. The second barrier layer is then disposed over the first barrier layer. This system has relatively low permeability to moisture and is flexible. It may cover particles and provide moisture protection with a relatively small width edge seal.

Abstract: Systems and techniques for depositing multiple different organic precursors, with reactive gases, such as by plasma polymerization, are provided. Using multiple precursor materials may provide for a much larger process regime, thus enabling for precise tuning of barrier properties and stress of the films. A barrier film as disclosed herein may be used on variety of substrates and electronic devices to reduce the permeation of moisture and other atmospheric contaminants.

Abstract: Embodiments of the disclosed subject matter provide methods and systems including a nozzle, a source of material to be deposited on a substrate in fluid communication with the nozzle, a delivery gas source in fluid communication with the source of material to be deposited with the nozzle, an exhaust channel disposed adjacent to the nozzle, a confinement gas source in fluid communication with the nozzle and the exhaust channel, and disposed adjacent to the exhaust channel, and an actuator to adjust a fly height separation between a deposition nozzle aperture of the nozzle and a deposition target. The adjustment of the fly height separation may stop and/or start the deposition of the material from the nozzle.

Abstract: Embodiments disclosed herein provide devices having a nozzle die with one or more nozzles, each of which has one or more integrated skimmers. The use of an integrated nozzle/skimmer structure allows for higher-resolution printing in OVJP-type deposition techniques without requiring the use of a shadow mask by allowing for a relatively narrow organic material beam that can be placed at relatively high distances away from the substrate.

Abstract: A novel thin film encapsulated OLED panel architecture and a method for making the panels with improved shelf life is disclosed. The OLED panel consists of a plurality of OLED pixels; each OLED pixel is individually hermetically sealed and isolated from its neighboring pixels. The organic stack of the OLED pixel is contained within its own hermetically sealed structure, achieved by making the structure on a barrier coated substrate and using a first barrier material as the grid and a second barrier for encapsulating the entire OLED pixel. The first barrier material provides the edge seal while the second barrier disposed over the pixel provides protection from top down moisture diffusion. By isolating and hermetically sealing individual pixels; any damage such as moisture and oxygen ingress due to defects or particles, delamination, cracking etc. can be effectively contained within the pixel thereby protecting other pixels in the panel.

The mask opening may be adjusted to control the pattern of deposition of the material on a substrate, such as to correct for material buildup that occurs during deposition. Material may be collected from the cooled side walls for reuse.
