Abstract: A method of forming microelectronic systems on a flexible substrate includes depositing a plurality of layers on one side of the flexible substrate. Each of the plurality of layers is deposited from one of a plurality of sources. A vertical projection of a perimeter of each one of the plurality of sources does not intersect the flexible substrate. The flexible substrate is in motion during the depositing the plurality of layers via a roll to roll feed and retrieval system.

Abstract: Methods for forming a coating over a surface are disclosed. A method includes directing a first source of barrier film material toward a substrate in a first direction at an angle θ relative to the substrate, wherein θ is greater than about 0° and less than about 85°. Additionally, a method of depositing a barrier film over a substrate includes directing a plurality of N sources of barrier film material toward a substrate, each source being directed at an angle θN relative to the substrate, wherein for each θN, θ is greater than about 0° and less than about 180°. For at least a first of the θN, θN is greater than about 0° and less than about 85°, and for at least a second of the θN, θN is greater than about 95° and less than about 180°.

Abstract: OLED device structures are provided that include an OLED, a high index optical layer (HOL), a thin film barrier disposed over the high index optical layer, and a low index optical layer (LOL) disposed over the thin film barrier. It is shown that such devices provide acceptable color emission that is at least comparable to a conventional device, while also exhibiting improved efficiency and luminance.

Abstract: A first product as disclosed herein includes multiple devices, such as OLEDs, which are moveably connected to one another. The devices may be moveable from a first position in which they are stacked, closed, rolled, or the like, to a second expanded position in which they may be usable together as a single device. Active areas of the devices may be disposed within 3 mm from each adjacent or included active area when the device is in the first position, the second position, or both. Each active device may include a barrier film that covers at least a portion of the substrate and/or the active area of one or more of the devices.

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: Devices, components and fabrication methods are provided for improving the efficiency of OLED displays. An outcoupling component such as a microlens array (MLA) is attached to an OLED, with a relatively small distance between the MLA and the OLED. Cross-talk and back scattering are reduced by the use of colored lenses, focusing layers, and other methods.
