Description

Non-planar tempered glass with grain decoration

The present invention relates to a non-planar tempered glass with textured decoration, and more particularly to a non-planar tempered glass that does not require the use of a substrate to carry a grain pattern.

For the appearance of the article, a 3D tempered glass film protective film containing a textured film was gradually developed. Since such a tempered glass protective film has a textured film and a glass film, it can simultaneously enhance the aesthetic appearance of the article and the effect of easy cleaning.

The existing 3D tempered glass protective film containing the grain film usually has the structure of the grain film structure composed of ink (20 μm), NCVM, UV grain (30 μm), PET (50 μm), OCA (25 μm), and the whole process. The thickness is about 125 μm. Moreover, when it is to be bonded to the glass substrate in the future, it is necessary to cut the grain film to a thickness of 0.05 to 0.1 mm from the single side of the glass to be applied to the glass substrate.

Therefore, the conventional 3D tempered glass protective film containing the grain film is not only inefficiently bonded to the glass substrate because the overall thickness is too thick. At the same time, because it needs to be cut, it cannot be aligned with the edge of the glass (white edge is produced), which affects the aesthetic problem.

Therefore, how to overcome the above-mentioned shortcomings through the improvement of structural design has become one of the important topics to be solved by this undertaking.

The technical problem to be solved by the present invention is to provide a non-planar tempered glass with a decorative texture for the deficiencies of the prior art.

In order to solve the above technical problems, one of the technical solutions adopted by the present invention is to provide a non-planar tempered glass with a decorative texture, including a glass substrate, a solid optical decorative layer, a coating layer and a light shielding layer. The glass substrate has an inner surface to And an outer surface relative to the inner surface. The solid optical decorative layer is disposed on the glass substrate, wherein the surface of the solid optical decorative layer has a transfer pattern. The coating layer is disposed on the solid optical decorative layer to directly cover the transfer pattern. The light shielding layer is disposed on the coating layer, wherein the solid optical decorative layer and the coating layer are both covered by the light shielding layer.

In order to solve the above technical problems, another technical solution adopted by the present invention is to provide a non-planar tempered glass with a decorative texture, including a glass substrate, a solid optical decorative layer, and a light shielding layer. The glass substrate has an inner surface and an outer surface relative to the inner surface. The solid optical decorative layer is disposed on the glass substrate, wherein the surface of the solid optical decorative layer has a transfer pattern. The light shielding layer is disposed on the solid optical decorative layer to directly cover the transfer pattern, wherein the solid optical decorative layer is covered by the light shielding layer.

The beneficial effect of the present invention is that the non-planar tempered glass with grain decoration provided by the present creative embodiment can be provided by "the solid optical decorative layer is disposed on the glass substrate" and "the solid optical decorative layer The surface has a transfer pattern, and the coating layer is disposed on the solid optical decorative layer to directly cover the transfer pattern" so that the non-planar tempered glass does not need to provide an additional PET substrate , thereby reducing the overall thickness of the non-planar tempered glass.
