Embodiment Construction

[0070] In the following detailed description of the preferred embodiments, the same reference numerals are used for clarity to refer to substantially the same parts of the various embodiments by the same reference numerals.

[0071] It is obvious to a person skilled in the art that the invention is not restricted to the merely exemplary embodiments shown with reference to the drawings, but can be varied in various ways within the scope of the subject matter of the claims. In particular, it is also possible to combine features of individual exemplary embodiments with one another.

[0072] figure 1 The exemplary embodiment of the glass part 1 shown in is a substrate 10 , which is shown in cross-section. In this case, the substrate can be a glass or glass ceramic wafer or also a sapphire wafer. A thin glass substrate is preferred. The invention is basically suitable for substrates of different thicknesses, wherein deformation of the substrate due to internal stresses tends to ...

Abstract

The invention relates generally to a glass-made glass member with a thin-plate or sheet shaped substrate. The substrate has at least one chemically prestressed layer which has high requirements on the platness and evenness. A coating includes a hard antireflection layer system which is applied to the first surface of the substrate. A compensation layer for reducing a deformation of the substrate is applied on the relatively opposite surface. The invention further relates to a method for manufacturing such a glass member.

Description

technical field [0001] The invention generally relates to a glass part comprising a thin plate-like or sheet-like substrate of glass which has at least one chemically prestressed layer which has very high requirements for flatness and flatness. Furthermore, the invention relates to a method for producing such a glass part. Background technique [0002] Glass parts comprising a thin plate-like or sheet-like substrate made of glass, ie comprising so-called thin glass substrates, and having at least one functional layer today find numerous applications as protective glass or cover glass. For example, such glass parts have various applications as cover glass for smartphones or tablet computers. The demands placed on such glass parts or thin glass substrates, for example with regard to flatness or flatness, are already very high and are constantly increasing. [0003] In addition to the requirement for the glass part to have as little deformation as possible, there are other re...
