[0003] However, in the prior art, the color of the film layer formed on the surface of the shell by PVD coating technology is very limited. At present, the PVD film layer that can be widely prepared and used is mainly golden yellow, black, blue and other colors, which can be stably produced. There are even fewer colors

Embodiment Construction

[0016] see figure 1 , the casing 10 of a preferred embodiment of the present invention includes a base 11 and a color layer 13 formed on the surface of the base 11 . The color layer 13 appears blue.

[0017] The material of the substrate 11 can be metal, glass, ceramic or plastic.

[0018] The color layer 13 can be formed on the surface of the substrate 11 by magnetron sputtering. The color layer 13 is a tin oxynitride (SnON) layer. The color layer 13 may have a thickness of 300-450 nm. The color layer 13 visually presents blue to the naked eye, and the chromaticity area it presents is in the L range of the CIE LAB color system. * Coordinates between 35 and 38, a * Coordinates between 3 and 4, b * Coordinates are between -10 and -15.

[0019] The manufacturing method of the casing 10 of the present invention comprises the following steps:

[0020] A substrate 11 is provided. The material of the substrate 11 can be metal, glass, ceramic or plastic.

[0021] Put the su...

Abstract

The invention provides a shell with blue appearance. The shell comprises a base body and a color layer formed on the surface of the base body, wherein the color layer is a nitrogen tin oxide layer; the L* coordinate of the chromaticity area presented by the color layer in a CIE LAB color system is between 35 and 38, the a* coordinate is between 3 and 4, and the b* coordinate is between -10 and -15. The invention also provides a manufacturing method of the shell. The color layer enables the shell to show blue color so as to enrich the color of a vacuum coating layer.

Description

technical field [0001] The invention relates to a casing and a manufacturing method thereof, in particular to a casing with a blue appearance and a manufacturing method thereof. Background technique [0002] In order to make the casing of the electronic device rich in color, currently the decorative coating is mainly prepared by processes such as anodic oxidation, baking varnish, and porcelain baking. Compared with these traditional processes, PVD coating technology is more green and environmentally friendly, and the use of PVD coating technology can form a decorative color layer with a metallic texture on the surface of the product shell. [0003] However, in the prior art, the color of the film layer formed on the surface of the shell by PVD coating technology is very limited. At present, the PVD film layer that can be widely prepared and used is mainly golden yellow, black, blue and other colors, which can be stably produced. Colors are even rarer.
