Patent number: 11314114Abstract: A display device with a display element having a display surface and a cover glass sheet, having a first textured surface, such that the first textured surface is facing the display element. The first textured surface has a surface roughness defined by a first arithmetic amplitude value, Ra1, being equal to or greater than 0.12 ?m (Ra1?0.12 ?m) and a first spacing value, Rsm1, being equal to or greater than 45 ?m (Rsm1?45 ?m) both measured on an evaluation length of 12 mm and with a Gaussian filter of which the cut-off wavelength is 0.8 mm. The first textured surface is in direct contact with the display surface over at least a portion of a contact area of the first textured surface.Type: GrantFiled: August 7, 2019Date of Patent: April 26, 2022Assignee: AGC GLASS EUROPEInventors: Fabrice Sinapi, Etienne Degand, Ingrid Marenne, Zakaria Habibi

Patent number: 10787384Abstract: A glass sheet comprising at least one etched surface having a surface roughness defined, when measured on an evaluation length of 2 mm and with a Gaussian filter of which the cut-off wavelength is 0.8 mm, by 0.02?Ra?0.4 microns and 5?RSm?30 microns. The glass sheet has excellent anti-sparkling properties together with an anti-glare effect. The texturing of the glass sheet may obtained by the process of carrying the glass sheet horizontally on a conveyor, pre-treating the surface to remove defects that may prevent subsequent uniform etching, etching the surface with aqueous solution containing hydrofluoric acid spread in an uniform layer over the surface of the sheet, maintaining the etching solution until the etching is ended, and drying the etched sheet.Type: GrantFiled: October 31, 2018Date of Patent: September 29, 2020Assignees: AGC GLASS EUROPE, AGC INC.Inventors: Fabrice Sinapi, Eugenie Peyroux

Publication number: 20150191391Abstract: The present invention concerns a method of selective chemical etching of a glass sheet, using a mask, making it possible to limit the etching of the glass under the edges of the mask, and to obtain a glass sheet selectively etched with patterns which can be very small and of which the contours exhibit a high level of sharpness. In particular, the invention concerns a method for producing a selectively etched glass sheet, comprising (i) a masking step which comprises selectively depositing a crosslinkable organic liquid composition on one of the faces of the sheet, using at least one ink-jet head, and the cross-linking of said composition by exposure to ultraviolet radiation; (ii) an etching step during which the areas of said face which are not covered by the crosslinked composition are chemically etched; and (iii) a finishing step which comprises removing said crosslinked composition.Type: ApplicationFiled: June 7, 2013Publication date: July 9, 2015Applicant: AGC GLASS EUROPEInventors: Fabrice Sinapi, Christine Deneil

Patent number: 8206788Abstract: In the manufacture of electronic devices that use porous dielectric materials, the properties of the dielectric in a pristine state can be altered by various processing steps. In a method for restoring and preserving the pristine properties of a porous dielectric layer, a substrate is provided with a layer of processed porous dielectric on top, whereby the processed porous dielectric is at least partially exposed. A thin aqueous film is formed at least on the exposed parts of the processed porous dielectric. The exposed porous dielectric with the aqueous film is exposed to an ambient containing a mixture comprising at least one silylation agent and dense CO2, resulting in the restoration and preservation of the pristine properties of the porous dielectric.Type: GrantFiled: July 3, 2007Date of Patent: June 26, 2012Assignee: IMECInventors: Fabrice Sinapi, Jan Alfons B.
