[Previous Technology] [0002] With the development of wireless communication and information processing technology, portable electronic devices such as mobile phones and personal digital assistants (PDAs) are competing to emerge, enabling consumers to fully enjoy high-tech anytime and anywhere. All the conveniences brought. In order to increase the use personality of the portable electronic device, more and more portable electronic device casings begin to adopt the outer casing of the graphic display. [0003] Most of the patterns on the outer casing of the portable electronic device are directly fabricated on the outer surface of the casing, for example, by printing the pattern directly on the casing, or by forming an achromatic pattern on the surface of the casing by anodization or the like. Although the casing improves the visual monotony of the casing of the portable electronic device to a certain extent, the pattern formed on the casing by the above method lacks a three-dimensional feeling and lacks a metallic texture. SUMMARY OF THE INVENTION [0004] In view of the above, it is necessary to provide an outer casing having a sense of depth and a metallic texture. In addition, it is also necessary to provide a method of manufacturing the above casing.

[0007] A method of manufacturing a casing, comprising the steps of: [0008] providing a transparent substrate, the substrate comprising an outer surface and an inner surface opposite to the outer surface; [0009] forming a transparent primer layer on the outer surface; [0010 Applying a vacuum coating on the primer layer to form a translucent first vacuum coating layer completely covering the primer layer; [0011] forming a translucent first pattern layer on the first vacuum coating layer; [0012] removing a first vacuum coating layer not covered by the first pattern layer; forming a semi-transparent second pattern layer on the inner surface; [0014] vacuum coating treatment, the second pattern layer and A second vacuum coating layer is formed on the inner surface covered by the second pattern layer. [0015] Compared with the prior art, the outer casing is formed with a translucent ink pattern on the inner and outer surfaces of the transparent substrate, and the pattern of the inner surface exhibits a depth effect through the substrate. Further, a vacuum plating layer having the same shape as that of the ink pattern is formed under the ink pattern on the outer surface, and a vacuum plating layer is formed on the entire inner surface, so that the ink pattern not only has a metallic texture but also has a metallic texture to the entire outer casing. [Embodiment] 100116177 Form No. A0101 Page 5 of 12 1002027170-0 201244588 [0016] Referring to FIG. 1, a housing 30 of a preferred embodiment of the present invention includes a transparent substrate 31, a primer layer 32, and a first a 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. [0017] The substrate 31 is made of a transparent plastic, such as Polycarbon-ate, PC) engineering plastics, polymethyl methacrylate (PMMA). The base 31 can also be made of transparent glass. The base 31 includes an outer surface 311 and an inner surface 31 2 opposite the outer surface 311. [0018] The primer layer 32 is formed directly on the outer surface 311 of the substrate 31. The primer layer 32 is formed of a transparent paint. The primer layer 32 serves to increase the adhesion of the first vacuum coating layer 33. [0019] The first vacuum coating layer 33 is formed directly on the primer layer 32 and partially covers the primer layer 32. The first vacuum coating layer 33 is formed by a vacuum plating method such as evaporation or sputtering, which has a metallic appearance. Moreover, the first vacuum coating layer 33 is translucent. The first vacuum coating layer 33 is formed of a metal or a non-metal having a metal outer casing such as aluminum, aluminum oxide, cerium oxide, stainless steel or the like. The first vacuum coating layer 33 has a shape of a first pattern. The first vacuum coating layer 33 of the present embodiment is formed of aluminum, which has a silver-white metallic appearance. [0020] The first pattern layer 34 is directly formed on the first vacuum plating layer 33, and has the same shape as the first vacuum plating layer 33, and completely overlaps with the first vacuum plating layer 33. The first pattern layer 34 is formed of a translucent ink or lacquer, and the first pattern layer 34 may be added with a pigment as needed. 100116177 Form No. A0101 Page 6 of 12 1002027170-0 201244588 [0021] The second pattern layer 35 is formed on the inner surface 312 of the substrate 31, which partially covers the inner surface 312. The second pattern layer 35 is formed of a translucent ink or paint having a shape different from that of the first pattern layer 34. The first pattern layer 34 can be added with a pigment as needed. The second vacuum layer 36 is formed on the second pattern layer 35 and the inner surface 312 not covered by the second pattern layer 35. The second vacuum coating layer 36 has a metallic appearance which may be translucent or opaque. The second vacuum plating layer 36 has the same composition as that of the first vacuum plating layer 33. [0023] The protective layer 37 is formed on the first pattern layer 34 and the outer surface 311 not covered by the first pattern layer 34 for protecting the first pattern layer 34 and the first vacuum coating layer 33. Anti-erosion, abrasion resistance, scratch resistance and other protective properties. The protective layer 37 is composed of a transparent ink or a transparent paint. The protective layer 37 may also be added with a pigment as needed. [0024] A preferred method of manufacturing the outer casing 30 includes the following steps: [0025] First, the transparent substrate 31 is provided. The base 31 includes the outer surface 311 and the inner surface 31 2 . The transparent primer layer 32 is formed on the outer surface 311. [0027] A vacuum coating process is performed on the primer layer 32 to form a first vacuum coating layer 33 that completely covers the primer layer 32. The vacuum coating treatment may be evaporation, sputtering or arc ion plating. In the present embodiment, the first vacuum coating layer 33 is formed of a steamed mineral dry material. Forming the first pattern layer 34 on the first vacuum coating layer 33 or the like 表单100116177 Form No. A0101 Page 7 / Total 12 Page 1002027170-0 201244588 [0029] Retracting from the first pattern layer 34 The first vacuum film layer 33 is covered such that the remaining portion of the first vacuum coating layer 33 has the same shape as the first pattern layer 34. [0030] Then, the second pattern layer 35 is printed on the inner surface 312 of the substrate 31 by printing. [0031] Next, a vacuum coating process is performed to form the second vacuum mineral film layer 3β on the second pattern layer 35 and the inner surface 312 not covered by the second pattern layer 35. In the present embodiment, the second vacuum coating layer 36 is formed of an evaporated aluminum dry material. [0032] Finally, the transparent protective layer 37 is formed on the first pattern layer 34 and the outer surface 311 not covered by the first pattern layer 34 by spraying or the like. The protective layer 37 can be formed from a clear paint. Thereby, the outer casing 3 is obtained. [0033] The outer casing 30 is formed with a translucent ink pattern on both inner and outer surfaces of the transparent substrate 31, and the pattern of the inner surface exhibits a depth effect through the substrate. Further, the vacuum coating layer having the same shape as the ink pattern is formed under the ink pattern on the outer surface, and the vacuum plating layer is formed on the entire inner surface. The not only the ink pattern has a metallic texture, but also the entire outer casing has a metallic texture. [0034] It can be understood that the outer casing 3 can also omit its primer layer 32 from the material of the base 31. At this time, the first vacuum coating layer 33 is directly formed on the outer surface 311. [0035] It can be understood that the protection Layer 37 can also be omitted.
