摘要： The invention relates to 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, 5≦RSm≦30 microns, said glass sheet having the following optical properties, when measured from said etched surface: —a haze value of from 1 to 30%; —a clarity value of from 50 to 100%; —a gloss value at 60° of from 30 to 110 SGU. Such a glass sheet which is particularly suitable for display applications as cover glass. In particular, the glass sheet of the invention has excellent anti-sparkling properties together with an anti-glare effect. Moreover, the glass sheet of the invention also combines anti-glare and anti-sparkling properties with a “soft touch”.

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： 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.
