Patent number: 10899661Abstract: A glass article having a low level of grainy appearance that can appear to have a shift in the pattern of the grains with changing viewing angle of a display, or “sparkle.” The glass article—which, in some embodiments, is a transparent glass sheet—has small-angle-scattering properties and/or distinctness-of-reflected-image (DOI), leading to improved viewability in display applications, especially under high ambient lighting conditions. In some embodiments, the antiglare surface of the glass sheet is an etched surface, with no foreign coating present on the antiglare surface.Type: GrantFiled: December 11, 2018Date of Patent: January 26, 2021Assignee: CORNING INCORPORATEDInventors: Jacques Gollier, Shandon Dee Hart, Kelvin Nguyen, Alan Thomas Stephens, II, James Andrew West, Lu Zhang

Patent number: 10538452Abstract: Surface modification layers and associated heat treatments, that may be provided on a sheet, a carrier, or both, to control both room-temperature van der Waals (and/or hydrogen) bonding and high temperature covalent bonding between the thin sheet and carrier. The room-temperature bonding is controlled so as to be sufficient to hold the thin sheet and carrier together during vacuum processing, wet processing, and/or ultrasonic cleaning processing, for example. And at the same time, the high temperature covalent bonding is controlled so as to prevent a permanent bond between the thin sheet and carrier during high temperature processing, as well as maintain a sufficient bond to prevent delamination during high temperature processing.Type: GrantFiled: April 8, 2016Date of Patent: January 21, 2020Assignee: CORNING INCORPORATEDInventors: Robert Alan Bellman, Dana Craig Bookbinder, Theresa Chang, Jeffrey John Domey, Robert George Manley, Prantik Mazumder, Alan Thomas Stephens, II
