    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.

    Abstract: A display area (100a) includes a plurality of tiles each tile including an optically transparent layer (208). Each of the plurality of tiles includes a substrate (202) and a plurality of light sources (204′) positioned on the substrate. In addition, each of the plurality of tiles includes a non-transparent layer (206) extending between the transparent layer and the plurality of light sources. The non-transparent layer includes an opening (214) extending over an area between at least one of the plurality of light sources and the transparent layer. In addition, a seam extends between adjacent tiles of the plurality of tiles and the non-transparent layer extends across the seam.

    Abstract: Described herein are articles and methods of making articles, for example glass articles, including a sheet and a carrier, wherein the sheet and carrier are bonded together using a coating layer, which is, for example, a fluorocarbon polymer coating layer, and associated deposition methods and inert gas treatments that may be applied on the sheet, the carrier, or both, to control the fluorine content of the coating layer and van der Waals, hydrogen and covalent bonding between the sheet and the carrier. The coating layer bonds the sheet and carrier together with sufficient bond strength to prevent delamination of the sheet and the carrier during high temperature processing to while preventing a permanent bond at during high temperature processing while at the same time maintaining a sufficient bond to prevent delamination during high temperature processing.
