Description

Glass casing and display device

The present invention relates to a glass envelope and a display device using the same.

The outer casing of the prior electronic product is mostly made of plastic material, and the pattern and the character mark of the electronic product are usually directly formed on the outer surface of the plastic outer casing. However, the pattern and the text mark on the plastic case become blurred after being worn for a long time, which greatly affects the appearance of the electronic product.

In view of this, it is necessary to provide a beautiful and durable glass casing.

A glass casing includes a casing body and a decorative layer. The housing body is made of glass. The housing body has an outer surface that is exposed to the outside and an inner surface that is opposite the outer surface. The inner surface is a non-planar structure as a whole. At least a portion of the inner surface is located in a different plane relative to the other portions. A pattern is formed on the decorative layer. The decorative layer is attached to an inner surface of the outer casing body, and the glass outer casing further includes a protective layer covering the decorative layer.

A display device includes a glass casing and a display panel housed in the glass casing. The glass casing includes a casing body and a decorative layer. The housing body is made of glass. The housing body has an outer surface that is exposed to the outside and an inner surface that is opposite the outer surface. The inner surface is a non-planar structure as a whole. At least a portion of the inner surface is located in a different plane relative to the other portions. Formed on the decorative layer There are patterns. The decorative layer is attached to the inner surface of the outer casing body.

In contrast to the prior art, the glass envelope provided by the present invention forms a patterned decorative layer on its inner surface, thereby avoiding the adverse effect of the pattern on the appearance of the product due to the wear of the pattern.

The decorative layer 12 is attached to the entire inner surface 104 of the outer casing body 100 by the substrate 121. As shown in FIG. 3, the decorative layer 12 may also be formed only on non-planar regions on the inner surface 104. The material of the coating layer 122 is selected from the group consisting of one or more of an ultraviolet coating, a single-shaped coating, a double-shaped coating, a ceramic coating, an aqueous coating, and a plastic coating. A pattern is formed on the paint layer 122. The pattern can be used to identify the product. The coating layer 122 is formed on the substrate 121 by means of transfer printing. The manner of the transfer printing includes, but is not limited to, inkjet, shower, pad printing, screen printing, thermal transfer, water transfer, and laser engraving.

The protective layer 13 is overlaid on the paint layer 122 to protect text or graphics formed on the paint layer 122. The material of the protective layer 13 is selected from the group consisting of a combination of one or more of an acrylic acid resin, a vinyl monomer and an oligomer polymer, cerium oxide, a modified acryl resin, a polyvinyl alcohol resin, and a hydroxy resin acid.
