Abstract

The invention provides a glass etching solution, a method for etching glass by using the etching solution, a cover glass and a preparation method thereof. According to an embodiment of the present invention, the glass etching solution includes: ammonium fluoride; a surfactant; an acid; and water. The etching solution can effectively etch glass, and various glass products can be effectively etched by using the glass etching solution according to actual needs, so that the etched glass has corresponding properties. In particular, it should be pointed out that the use of the glass etchant to etch the cover glass can make the cover glass form an uneven rough surface, so that it has the function of anti-glare. In addition, the present invention also provides a method for etching glass with a glass etchant and a method for preparing cover glass.

Description

technical field [0001] The present invention relates to the field of glass processing, in particular, to a glass etchant and its application, and more specifically, to a glass etchant, a method for etching glass, a method for preparing cover glass, cover glass and a display device having the same. Background technique [0002] As an input device for human-computer interaction, touch screens have been widely used in electronic devices such as mobile phones, tablet computers, and ultrabooks. However, there are still many deficiencies in the touch screen widely used at present. Specifically, when consumers use the touch screen, they need to touch it with their fingers, which will inevitably produce fingerprints or dirt, which will affect the visual effect. Moreover, when the touch screen is used in a strong light environment, glare will be generated, causing visual discomfort or even loss of brightness. In addition, in order to make the touch screen difficult to break and dura...
