  • Patent number: 10684543
    Abstract: A projection screen for displaying an image is disclosed. The projection screen may comprise an electrode, a plurality of cavities, an upper and lower substrate, and a hydrophobic liquid. The electrode may be disposed on a lower substrate. The hydrophobic liquid may be disposed between the upper substrate and lower substrate. The plurality of cavities may be disposed between the upper and the lower substrates. The projection screen may be associated with the electrode. The projection screen may be configured such that an application of an appropriate voltage to the electrode changes optical properties of the projection screen. Optical properties of the projection screen may comprise transparent and opaque states. Modulation between transparent and opaque states may be in such speed that a viewer sees the projection of a projector on the projection screen in the opaque state as well as sees through the projection screen in the transparent state with no perceived interruptions.

  • Publication number: 20200171799
    Abstract: Described herein are articles and methods of making articles, for example glass articles, comprising a thin sheet and a carrier, wherein the thin sheet and carrier are bonded together using a modification (coating) layer, for example a cationic polymer coating layer, and associated deposition methods, the carrier, or both, to control van der Waals, hydrogen and covalent bonding between the thin sheet and the carrier. The modification layer bonds the thin sheet and carrier together with sufficient bond strength to prevent delamination of the thin sheet and the carrier during high temperature (?600° C.) processing while also preventing formation of a permanent bond between the sheets during such processing.
