Embodiment Construction

[0210] figure 1 A schematic diagram of a coated glass substrate according to an exemplary embodiment of the present invention is shown.

[0211] A glass substrate 10 , which may also have a structure, is coated with at least one functional layer 20 in a first step according to the method of the invention. The functional layer may be any functional layer within the scope of the present invention, which may be a single layer or a plurality of layers. In the exemplary embodiment shown, this is an antireflection coating consisting of three layers of a medium-refractive, high-refractive and low-refractive layer system. Of course, a further functional layer in the form of a single layer or a multilayer can also be present.

[0212] The glass substrate 10 can also be coated on both sides (not shown).

[0213] In a second step, the coated glass substrate 10 together with the functional coating 20 is chemically prestressed. This is done in a conventional way. The glass substrate ...

Abstract

The invention relates to a method for producing a coated, chemically prestressed glass substrate having anti-fingerprint properties, wherein the method comprises the following steps: applying at least one functional layer to a glass substrate; chemically prestressing the coated glass substrate by means of ion exchange, wherein existing smaller alkali metal ions are exchanged for larger alkali metal ions, and are enriched in the glass substrate and the at least one functional layer; activating the surface of the at least one functional layer, wherein, if more than one functional layer is present, the surface of the outermost or uppermost layer is activated, and the activating of the surface of the at least one functional layer is carried out using one of the described variations (1) to (8); and applying an amphiphobic coating to the at least one functional layer of the glass substrate, wherein, as a result of the activation process, the functional layer interacts with the amphiphobic coating. The glass substrate provides a unique combination of advantageous properties, such that, as well as anti-fingerprint properties and an increased scratch and breakage resistance, an improved durability of the amphiphobic coating is also achieved.

Description

technical field [0001] The invention relates to a method for producing a coated, chemically prestressed glass substrate with anti-fingerprint properties and to the produced glass substrate. Background technique [0002] The rapidly growing market for touch screens or sensor screens, for example in touchpad applications with interactive input, leads to ever-increasing requirements in multifunctional touch applications. Touch screens are used, for example, to operate smartphones, automated teller machines, information monitoring screens, in particular in railway stations, in gaming machines or in industrial applications for controlling machinery. This is used in particular for mobile products such as notebooks, laptops, clocks, mobile phones or positioning devices. Other fields of application in which touching glass or glass-ceramic surfaces is important for handling or use are in particular refrigerated cabinets or cabinets, such as glass-ceramic and industrial cooking hobs,...
