Description

Housing with graphic display mark and manufacturing method thereof

The present invention relates to a housing, and more particularly to an outer casing having a graphic display mark applied to a portable electronic device and a method of manufacturing the same.

With the development of wireless communication and information processing technology, mobile electronic devices such as mobile phones and personal digital assistants (PDAs) are competing to emerge, enabling consumers to fully enjoy the convenience brought by high technology whenever and wherever possible. In order to increase the use personality of the portable electronic device, more and more portable electronic device housings have begun to adopt a housing with a graphic display mark.

Referring to FIGS. 1 and 2, the housing 10 having the graphic display mark has a substantially rectangular plate shape and includes a base 11, an opaque ink layer 13, and a semi-transmissive ink layer 15. The base 11 is a substantially rectangular transparent plate comprising an outer surface 111 and an inner surface 112 opposite the outer surface 111. The opaque ink layer 13 is applied to the inner surface 112 of the substrate 11, and a pattern region 133 is formed at a corresponding position on the inner surface 112. The semi-transmissive ink layer 15 is coated on the opaque ink layer 13 such that the opaque ink layer 13 is interposed between the translucent ink layer 15 and the substrate 11.

When the housing 10 having the graphic display mark is manufactured, the method includes the steps of: firstly, providing a base 11 made of a transparent material while shielding the inner surface 112 of the base 11 at a position where the pattern area 133 is pre-formed. Processing; next, applying a layer of opaque ink to the inner surface 112 The layer 13 is such that after the mask is removed, a pattern area 133 is formed on the inner surface 112 of the substrate 11; finally, a semi-transmissive ink layer 15 is coated on the opaque ink layer 13, so that the layer is not transparent. The photo ink layer 13 is interposed between the translucent ink layer 15 and the substrate 11, that is, the manufacture of the outer casing 10 having the graphic display mark is completed.

The housing 10 with the graphic display mark is mounted on the portable electronic device, and a backlight is disposed at a position below the graphic area 133 of the housing 10, and the backlight is not illuminated during use. The graphics area 133 is shielded from the semi-transmissive ink layer 15 and is not easily visible; and when the backlight is illuminated, the graphics area 133 is illuminated by the backlight and displayed on the substrate 11 In addition, the use performance of the portable electronic device is enhanced.

However, when the semi-transparent ink layer 15 is applied to the opaque ink layer 13 during the manufacturing process of the outer casing 10 having the graphic display mark, the orange peel phenomenon is often caused by uneven printing. , greatly affecting the light transmission effect of the outer casing 10, reducing the production yield and performance of the outer casing.

In view of the above, it is necessary to provide an outer casing with a graphic display mark which can effectively improve the light transmission effect and the use performance.

It is also necessary to provide a manufacturing method which can effectively improve the production yield of the outer casing having the graphic display mark and avoid the occurrence of orange peel.

A casing having a graphic display mark, the casing having a graphic display mark comprising a base body and an opaque ink layer, the base body being located at an outermost layer, comprising an outer surface and an inner surface opposite to the outer surface; The substrate is made of a translucent material, and the opaque ink layer is applied to the base A graphic area is formed on the inner surface of the body and at a corresponding position on the inner surface.

A method of manufacturing a housing with a graphic display mark, comprising the steps of: providing a substrate made of a translucent material, the substrate comprising an outer surface and an inner surface opposite the outer surface, the inner surface of the substrate A masking process is performed at a position where the pattern region is pre-formed; an opaque ink layer is coated on the inner surface, and after the mask is removed, a pattern region is formed correspondingly on the inner surface of the substrate.

Compared with the prior art, the outer casing of the graphic display mark is directly coated with an opaque ink layer on a substrate made of a semi-transparent material, and a pattern area is formed on the translucent substrate. A housing that displays a graphic display mark. The manufacturing method of the outer casing with the graphic display mark effectively avoids the occurrence of the orange peel phenomenon in the manufacturing process, and greatly improves the production yield and the use performance.

Referring to FIGS. 3 and 4, the outer casing 30 having the graphic display mark has a substantially rectangular plate shape and includes a base 31 and an opaque ink layer 33. The base body 31 has a substantially rectangular plate shape and is made of a translucent PC (polycarbonate) engineering plastic material. The base 31 includes an outer surface 311 and an inner surface 312 opposite the outer surface 311. The opaque ink layer 33 is applied to the inner surface 312 of the substrate 31, and a pattern region 333 is formed at a corresponding position on the inner surface 312. The graphic area 333 can be a caller ID graphic, a short message prompt graphic, or a glare display graphic. When the outer casing 30 having the graphic display mark is manufactured, the method includes the following steps: providing a base 31 made of a translucent material, the base 31 including an outer surface 311 facing the user side and one outer The surface 311 is opposed to the inner surface 312; a masking process is performed on the inner surface 312 of the base 31 at a position where the pattern area 333 is pre-formed.

A opaque ink layer 33 is coated on the inner surface 312. After the mask is removed, a pattern area 333 is formed on the inner surface 312 of the substrate 31, that is, the outer casing 30 having the graphic display mark is completed. Manufacturing.

The housing 30 with the graphic display mark is mounted on a portable electronic device (not shown), and a backlight (not shown) is disposed at a position below the graphic area 333 of the housing 30. In use, when the backlight is not illuminated, the graphics area 333 is obscured by the translucent substrate 31 and is not easily visible; and when the backlight is illuminated, the graphics area The 333 is illuminated by the backlight and displayed on the translucent substrate 31, which enhances the use performance of the portable electronic device during use, and satisfies the individual needs of the user.

The outer casing 30 with the graphic display mark is coated with an opaque ink layer 33 on the inner surface of the base 31 made of a semi-transparent material, and a pattern area 333 is formed on the semi-transparent substrate 31, thereby obtaining a A housing 30 is shown that graphically displays the indicia. The entire manufacturing process has fewer processes, effectively avoiding the occurrence of orange peel in the manufacturing process, and improving production yield and performance.

In summary, the present invention complies with the requirements of the invention patent, and patents are filed according to law. Application. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
