1. Technical Field
The exemplary disclosure generally relates to housings and portable electronic devices using the housings.
2. Description of Related Art
Currently, portable electronic devices with wireless communication capability, such as mobile phones, are widely used. Consumers can choose to purchase a specific model not only based on performance but also other factors, such as appearance.
Typically, a three-dimensional pattern is formed on the housing by laser holography, to improve the external appearance of the housing. However, the three-dimensional pattern of the housing made by above-mentioned method, cannot meet the requirement of attractive appearance of the housing.
Therefore, there is a room for improvement in the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the exemplary housing and method of manufacturing the housing. Moreover, in the drawings like reference numerals designate corresponding parts throughout the several views. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like elements of an embodiment.
Referring to the
The substrate 12 is made of a thermoplastic material such as polyethylene, polycarbonate, acrylonitrile bivinyl styrene, polymethyl methacrylate, or any combination thereof. The substrate 12 is integrally molded on the decorative layer 14 entirely covering one surface of the protective layer 149. It is understood that the substrate 12 may be directly integrally molded with the substrate 142 entirely covering the second conductive coating 148, when the decorative layer 14 does not include the protective layer 149. The substrate 12 also may be hardened to improve the abrasion thereof. The substrate 12 has a thickness of approximately 0.1˜0.2 millimeter.
The material for the substrate 142 may be a resin sheet of a single body or a copolymer of a polypropylene, polyamide, polycarbonate, polymethyl methacrylate or other. The first conductive coating 144 is made of Indium Tin Oxid (ITO) film. The first conductive coating 144 has a thickness of approximately 2˜10 micrometers (μm), and preferably has a thickness of 5 micrometers. The first conductive layer 144 has a first electrical interface 1442 used to electrically connect to a power source 30 of a portable electrical device 100. The electrically conductive ink layer 146 may be produced using ordinary printing methods, such as the gravure printing method, the screen printing method or the offset printing method.
The second conductive layer 148 is made of silver paste or conductive paint. The second conductive layer 148 has a thickness of approximately 8˜10 micrometers (μm). The second conductive layer 148 has a second electrical interface 1482 used to electrically connect to the power source 30. The protective layer 149 is made of an opaque, colored material such as a polyvinyl based resin, a polyamide based resin, a polyester based resin, an acrylic resin, a polyurethane based resin, a polyvinyl acetal based resin, a cellulose ester based resin, or an alkyd resin is preferred as a binder with a colorant containing a pigment or dye of a desired hue. In formation of the protective layer 149, an ordinary ink printing method such as gravure, screen, or offset printing may be used. The protective layer 149 protects the second conductive layer 148 from damage when the decorative layer 14 is integrally molded on the substrate 12.
It is to be understood, when the first electrical interface 1442 of the first conductive coating 144 and the second electrical interface 1482 of the second conductive layer 148 are electrically connected to a power source 30 of the portable electronic device 100, an electrical field between the first conductive coating 144 and the second conductive layer 148 is created, the electrically conductive ink layer 146 then presents a pattern 101 that can be seen from the substrate 142, and the pattern 101 provide an attractive appearance for the first housing 10.
It is to be understood, however, that even though numerous characteristics and advantages of the exemplary disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
