  • Patent number: 10137642
    Abstract: Methods to form cross-linked or sintered objects include forming walls for reservoir layers, with cross-linkable or sinterable materials deposited in the reservoir layers. The cross-linkable or sinterable materials can then be cross-linked, e.g., changing the structure of the deposited cross linkable materials, or sintered, e.g., heat treated to fused the sinterable materials together. The walls for the reservoir layers can be removed after the objects are formed.

  • Publication number: 20180190614
    Abstract: MicroLED devices can be transferred in large numbers to form microLED displays using processes such as pick-and-place, thermal adhesion transfer, or fluidic transfer. A blanket solder layer can be applied to connect the bond pads of the microLED devices to the terminal pads of a support substrate. After heating, the solder layer can connect the bond pads with the terminal pads in vicinity of each other. The heated solder layer can correct misalignments of the microLED devices due to the transfer process.

  • Patent number: 9997353
    Abstract: A composite substrate includes a single crystal silicon layer on a glass or glass ceramic layer on a support layer can be used to form GaN layer without cracks. The glass or glass ceramic layer can have a set point and/or strain point below the deposition temperature of GaN, which can assist in releasing stress in the deposited GaN layer. Additionally, the composite substrate can be exposed to a heated and dry hydrogen ambient to reduce an oxide layer between the silicon layer and the glass or glass ceramic layer, to allow the formation of free standing GaN layer.

  • Patent number: 9976420
    Abstract: An aspirating seal assembly for use in a turbine engine is provided. The aspirating seal assembly includes a face seal and a rotary component. The face seal includes a first annular seal surface, and the rotary component includes a second annular seal surface positioned adjacent the first annular seal surface and defining a seal interface therebetween. The face seal is configured to discharge a flow of air towards the seal interface. The seal assembly also includes a first seal member extending between the first and second annular seal surfaces such that the flow of air induces a back pressure across the seal interface, and a second seal member positioned radially inward from the first seal member and extending between the first and second annular seal surfaces. A length of the second seal member is selected to increase the back pressure induced across the seal interface.

  • Publication number: 20170317107
    Abstract: Displays can be fabricated using driver transistors formed with high quality semiconductor channel materials, and switching transistors formed with low quality semiconductor channel materials. The driver transistors can require high forward current to drive emission of the OLED pixels, but might not require very low leakage current. The switching transistors can require low leakage current to allow the pixel capacitor to retain the signal level for accurate OLED device emission, preventing abnormal displays or cross talks.
