摘要： 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.

摘要： 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 μm (Ra1≥0.12 μm) and a first spacing value, Rsm1, being equal to or greater than 45 μm (Rsm1≥45 μm) 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.

摘要： A cover glass sheet configured to cover a display element including a first textured surface having a surface roughness defined by a first arithmetic amplitude value, Ra1, and a first spacing value, Rsm1. Both values are measured on an evaluation length of 12 mm with a Gaussian filter wherein the cut-off wavelength is 0.8 mm. A first transmission haze value, Haze1, is equal to or lower than 10%. A first clarity value, Clarity1, and a second textured surface comprise a second transmission haze value, Haze2. The second transmission haze value, Haze2, of the second textured surface is equal to or lower than a maximum haze value, HazeMax (Haze2≤HazeMax), wherein HazeMax=4.99−8.13 10−1(Haze1)+4.67 10−2(Clarity1) %.

摘要： 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.

摘要： The invention relates to a glass substrate having enhanced optical properties for optoelectronic devices, wherein said substrate is totally or partially textured, by means of a chemical attack, on at least one of the surfaces thereof with a set of geometric patterns such that the arctangent of the ratio of the mean height of the patterns, Rz, to half the mean distance between the peaks of two contiguous patterns, RSm, is at least equal to an angle of 35° and at most equal to an angle of 80°.
