Problems solved by technology

[0031] Therefore, the manufacture of glassware with anti-glare surfaces requires complex manufacturing methods, often using health-hazardous and environmentally problematic reagents, such as HF, and / or lengthy manufacturing processes
However, the obtained surface is not sufficiently matte to ensure satisfactory anti-glare properties

Embodiment Construction

[0144] figure 1The left part of a shows a photographic view of the surface of a masked but not pre-hydrophobized glass article. When a masking solution is applied, the result is a small number of relatively large "islands", with an average diameter greater than 1 mm, which also face a relatively large uncovered surface area. In this way, the surface of the glass article cannot be visually inconspicuously uniformly matted, which leads to a reduction in glare of the display.

[0145] exist figure 1 In the left part a of , in order to identify the size, the scale in the upper right corner is marked as 1000mm, and the diameter of the "island" is 1099.08μm.

[0146] In contrast to this, figure 1 Part b on the right shows a photographic view of the surface of the glass article masked after hydrophobization. In this way, a homogeneous distribution of the masking liquid or masking solution in the form of droplets is obtained, the diameter of the droplets being between 1 μm and 100...

Abstract

The present invention generally relates to glass articles, and preferably glare-free glass articles, and a method for producing glare-free glass articles.

Description

technical field [0001] The present invention generally relates to glass articles, preferably anti-glare glass articles, and methods for manufacturing preferably anti-glare glass articles. Background technique [0002] For applications such as in displays, surfaces with the lowest possible reflection of visible light are required. For this purpose, anti-reflection coatings are usually used. [0003] For example, Cao et al. proposed nano-zeolite-based coatings (Microporous and Mesoporous Materials 263 (2018), 62-70). The coating is antifogging and also antireflective, ie reduces reflections (reflexionsmindernd). The coating is applied by dipping. [0004] Zhang et al. propose an anti-fog layer that is also designed to reduce reflections (Journal of Colloid and Interface Science 374 (2012), 89-95). The coating is applied by spin coating. [0005] Arabatzis et al. proposed a photocatalytic, self-cleaning, and reflection-reducing coating for photovoltaic applications (Solar ...
