Embodiment Construction

[0020] see figure 1 , the shell 30 of the preferred embodiment of the present invention comprises a transparent substrate 31, a primer layer 32, a first vacuum coating layer 33, a first pattern layer 34, a second pattern layer 35, a second vacuum coating layer 36 and a protective layer 37.

[0021] The base 31 is made of transparent plastic, such as (Poly Carbonate, PC) engineering plastic, polymethyl methacrylate (Polymethyl Methacrylate, PMMA) and the like. The base body 31 can also be made of transparent glass. The base body 31 includes an outer surface 311 and an inner surface 312 opposite to the outer surface 311 .

[0022] The primer layer 32 is directly formed on the outer surface 311 of the substrate 31 . The primer layer 32 is formed of transparent paint. The primer layer 32 is used to improve the adhesion of the first vacuum coating layer 33 .

[0023] The first vacuum coating layer 33 is directly formed on the primer layer 32 and partially covers the primer lay...

Abstract

The invention provides a shell comprising a transparent base body, a semi-transparent first vacuum coating layer formed on the outer surface of the base body, a semi-transparent first pattern layer formed on the first vacuum coating layer, a semi-transparent second pattern layer formed on the inner surface of the base body, and a second vacuum coating layer formed on the second pattern layer, wherein the first vacuum coating layer covers a part of the outer surface; the first pattern layer and the first vacuum coating layer are in the same shape and are superposed with the first vacuum coating layer; and the second pattern layer covers a part of the inner surface. The second vacuum coating layer covers the second pattern layer and the part of the inner surface which is uncovered by the second pattern layer. The invention further provides a manufacturing method of the shell.

Description

technical field [0001] The present invention relates to a decorative shell and its manufacturing method. Background technique [0002] With the development of wireless communication and information processing technology, portable electronic devices such as mobile phones and personal digital assistants (PDA) are emerging, allowing consumers to fully enjoy the convenience brought by high technology anytime and anywhere. In order to increase the use individuality of the portable electronic device, more and more portable electronic device casings start to adopt a graphical display casing. [0003] Most of the graphics on the casing of existing portable electronic devices are directly produced on the outer surface of the casing, such as by directly printing the pattern on the casing, or forming a color pattern on the surface of the casing by anodic oxidation or the like. Although this casing improves the visual monotony of the casing of the portable electronic device to a certai...
