Abstract: Devices and techniques are provided in which a transparent substrate is scored to provide a non-planar surface on one side of the substrate. An OLED is then disposed on the other side of the scored substrate and optically coupled to the substrate. The scored surface provides improvements to outcoupling of light generated by the OLED, with little or no additional thickness relative to the OLED alone.

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.

Abstract: Embodiments of the disclosed subject matter provide a device having a print head that includes a micronozzle array of depositors to deposit a material on a substrate. A reflective optical device may reflect a signal output by at least one optical sensor, and to reflect the signal from a surface of the substrate to the optical sensor. A processor may determine a distance between the optical sensor and the target surface of the substrate. The device may include one or more actuators coupled to the at least one print head to move the print head relative to an internal reference frame and adjust a position of the print head to the substrate. The sensor may be fixedly coupled with a mount to the internal reference frame. The print head may be configured to move independently of the optical sensor in at least one axis of linear or rotational motion.

Abstract: Methods of modulating flow during vapor jet deposition of organic materials are provided. A method may include ejecting a vapor entrained in a delivery gas from a nozzle onto a substrate upon which the vapor condenses. A confinement gas may be provided that has a flow direction opposing a flow direction of the delivery gas ejected from the nozzle. A vacuum source may be provided that is adjacent to a delivery gas aperture of the nozzle. The method may include adjusting, by an actuator, a fly height separation between a deposition nozzle aperture of the nozzle and a deposition target.
