3 is a perspective view illustrating only a case part of a portable terminal according to an embodiment of the present invention, FIG. 4 is a rear perspective view of FIG. 3, and FIG. 5 is a partial cross-sectional view of part A of FIG. 3.

The case of the portable terminal according to an embodiment of the present invention includes a window 10, a surface treatment layer 11, a frame and a coating layer 40.

The window 10 is formed of a light-transmissive material so that the image or the screen of the display unit can be viewed. A hydrophobic rubber part may be additionally provided on the outer side of the window 10 to form an edge of the window 10.

The surface treatment layer 11 is formed by coating a surface treatment agent on the window 10 to lower the surface energy of the window 10, or by arranging a hydrophobic fluorine-based component or a silicon-based component on the surface of the window 10. In particular, as a method of allowing the surface layer to contain a fluorine-based component, tridecafluorooctyltriethoxysilane (trade name: DYNASYLAN F8261, Degussa-Huls), heptadecafluorodecyltrimethoxysilane (trade name: TSL8233, Toshiba Physical Vapor Deposition (PVD), Chemistry using at least one selected from silicon / KBM-7803, Shinetsu) and heptadecafluorodecyltriisopropoxysilane (trade name: XC95-A9715, Toshiba Silicone) The surface treatment layer 11 is formed on the window 10 by using one or more treatment methods such as vapor deposition (CVD), spray (spray), printing, and dipping.

For this reason, even if paint or a coating liquid adheres to the surface treatment layer 11, a washing | cleaning operation is easy.

The frame includes a first frame 20 in which the window 10 is disposed, and a second frame 30 formed to protect the window 10 and the first frame 20.

The coating layer 40 is formed on the surface of the frame to realize color, to form a smooth and smooth surface, and to conceal the rough surface state after the injection of the frame. The coating layer 40 may be formed of a paint layer for realizing color and a protective layer for protecting the paint layer and forming a smooth surface.

Hereinafter, a remarkable effect according to an embodiment of the present invention will be described as compared to the case of the portable terminal when the window is not surface treated.

FIG. 6 illustrates a plan view of a portable terminal in stages of a manufacturing process when no surface treatment is performed on the window, and FIGS. 7A to 7C illustrate defect types when coating is completed in the manufacturing process of FIG. 6. Figure 7d is a photograph enlarged 100 times the portion A of Figure 3 to look at the defective portion of the upper surface of the case is completed cleaning, Figure 9 is a case of finishing painting and surface protection treatment process according to an embodiment of the present invention The actual picture of the painting and coating of part A of 3 is completed.

Referring to Figure 6, the process of painting and surface protection of the case in the manufacturing process of the mobile phone is as follows.

First, after the window 10 is disposed, the frame is injection molded including the window 10 (S1). The frame including the window 10 is masked by using a film or a jig in order to paint or surface-protect the desired portion (S2). After the painting or surface protection process (S3), masking is removed, and the upper surface of the case including the window 10 and the frame is cleaned (S4).

Looking at the upper surface of the case after cleaning, as shown in Figs. 7A to 7C, a poor type of painting or surface protection treatment appears. The failure type is exaggerated, but in fact, most of the products that have completed the process, when observed in detail, as shown in FIG. 7D, the painted or surface-protected portion is not smooth or penetrates the surface of the window 10. This does not form a good appearance. Also, if this causes scratches on the surface, contaminants can penetrate into the gaps.

However, in the case of a portable terminal according to an embodiment of the present invention, as shown in FIG. 9, the portion corresponding to A of FIG. 3 has a very good coating surface compared to FIG. 7D.

In other words, the case of the portable terminal according to an embodiment of the present invention is to reduce the surface energy of the window, the paint or coating liquid is peeled off the surface of the window through a simple cleaning operation, masking the film 50, etc. In the case of coating surface defects caused by tolerances, correction and cleaning operations are easy.

Hereinafter, a portable terminal manufacturing method according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

8 illustrates a plane of a portable terminal according to a step of a manufacturing process when the window 10 is subjected to a surface energy reduction treatment according to an embodiment of the present invention.

In order to manufacture a case of the portable terminal, first injection molding the first frame 20 to support the internal space of the portable terminal, and guide the components can be arranged. The transmissive window 10 including the surface treatment layer 11 subjected to the surface energy reduction treatment is disposed or attached to the injection molded first frame 20 (S11).

Then, including the window 10 and the first frame 20, the second frame 30 is integrally injection molded (S12). The molded case is masked using a jig or film 50 and the like, and a paint or a coating liquid is applied (S13). The masking is removed, and the cleaning operation removes the paint or coating liquid applied to the unnecessary portion (S14).

Even if paint or coating liquid gets on a part of the window 10 after the coating operation due to the tolerance of attaching the film 50 or the masking operation, the paint or the coating liquid is carried out through a simple and simple cleaning operation such as wiping and wiping the window 10. Get out of this. That is, in the case of the window 10 having the surface treatment layer 11, it is very easy to correct the appearance defect due to the tolerance.

FIG. 10 illustrates a plane of a portable terminal according to a step of a manufacturing process when the window 10 is subjected to a surface energy reduction treatment and an edge according to another embodiment of the present invention.

As shown, in the present embodiment, a step (S11 ') of additionally injecting and molding a hydrophobic rubber portion 60 into the window 10 is added to the case fabrication process of the previous embodiment. In addition, the film 50 is attached as an example of masking. The hydrophobic rubber part 60 is similar to the window 10 having the surface treatment layer 11, so that the paint or the coating liquid comes off through a simple cleaning operation such as rubbing and wiping the window 10. It is easy to correct the appearance defects.

The portable terminal and the method of manufacturing the portable terminal are not limited to the configuration and method of the embodiments described above, but the embodiments are configured by selectively combining all or part of the embodiments so that various modifications can be made. May be
