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(Haze1)+4.67 10(Clarity1) %.

Cover glass sheet

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 &#x3bc;m (Ra1&#x2265;0.12 &#x3bc;m) and a first spacing value, Rsm1, being equal to or greater than 45 &#x3bc;m (Rsm1&#x2265;45 &#x3bc;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.

Display device

The invention relates in an embodiment to a glass substrate with increased weathering and chemical resistance where a surface bears a SiOxCy coating wherein the O/Si atomic ratio is comprised between 1.75 and 1.95 and the SiOxCy coating thickness is comprised between 10 nm and 80 nm. Other embodiments relate to glazings having a glass substrate where a surface bears a SiOxCy coating wherein the O/Si atomic ratio is comprised between 1.2 and 1.95 and the SiOxCy coating thickness is comprised between 10 nm and 80 nm.

Glass substrate with increased weathering and chemical resistance

The invention relates to substrates, in particular to transparent substrates, optionally colored, coated with an infrared-reflecting layer and capable of being used as glazing in buildings or in vehicles. Said coated substrates are made up of the combination of a glass substrate in which the composition has a redox of less than 15%, characterized by infrared reflection RIRso that RIR&#x2265;1.087*TL, wherein TLis the light transmission of the glass, and an infrared reflecting layer characterized by light transmission TLso that TL&#x2265;1.3*TIR, wherein TIRis the infrared transmission of the layer.

Coated substrate for solar control

The invention relates to laminated glazing comprising a substrate, in particular a transparent substrate, optionally colored, coated with an infrared-reflecting layer and capable of being used as glazing in buildings or in vehicles. The coated substrate is made up of the combination of a glass substrate in which the composition has a redox of less than 15%, characterized by infrared reflection RIRV so that RIRV&#x2265;1.087*TLV, wherein TLV is the light transmission of the glass, and an infrared reflecting layer characterized by light transmission TLC so that TLC&#x2265;1.3*TIRC, wherein TIRC is the infrared transmission of the layer.

Laminated glazing for solar control
