Problems solved by technology

[0004] However, the above method has a long process and consumes a lot of materials, and because a layer of Deco-film is pasted, the overall thickness of the Cover lens increases, which reduces the transmittance and affects the visibility of the Cover lens.

Abstract

The invention relates to cover plate glass and a preparation method thereof. The preparation method comprises the following steps: taking a glass substrate, wherein the surface of the glass substrate is provided with a grain pattern area; sequentially depositing a metal layer and a photoresist layer on the surface of the glass substrate, wherein the thickness of the metal layer is 30 to 200 nm, the metal layer is made of one or more of silver, molybdenum and chromium, the metal layer is provided with a first to-be-windowed area corresponding to the grain pattern area, and the thickness of the photoresist layer is 0 to 15 [mu]m, and the photoresist layer is provided with a second to-be-windowed area corresponding to the grain pattern area; removing the metal layer with the first to-be-windowed area and the photoresist layer with the second to-be-windowed area by a laser engraving method so as to enable the grain pattern area to expose, thus obtaining a to-be etched plate; carrying out etching on the to-be etched plate; and removing the rest metal layer and photoresist layer, thus obtaining a finished product. The preparation method has the advantages that the increase of the thickness of the cover plate glass is avoided, and the visualization and a stereoscopic effect of grain patterns are improved.

Description

technical field [0001] The invention relates to the technical field of touch sensing, in particular to a cover glass and a manufacturing method thereof. Background technique [0002] With the rapid development of communication technology, touch sensor (Touch Sensor) products are more and more widely used, and at the same time, as an important product with Touch Sensor - Cover Glass (Cover Lens) has also been greatly developed. [0003] At present, in order to make the effect of Cover Lens more beautiful, designers usually paste a layer of PET film with texture patterns (such as CD texture) on the surface of Cover Lens. This layer of PET film is called Deco-film in the industry. It is made by coating UV glue on the PET film first, pressing out the texture pattern through the mold, and then making it through PVD electroplating color film and printing process to form color difference and make various gorgeous patterns. , and finally attach the Deco-film to the Cover lens to ma...
