Abstract
Description
BACKGROUND OF THE
In the portable user equipment provided with the light emitting display device, a transparent window for protecting the light emitting display device is provided as a part of the case. A portion of the case adjacent to the transparent window may have a color that allows the user to feel a sense of beauty when viewed with the eyes of a person. The portion showing such a color can be referred to as a pattern portion in this specification.
In the conventional technique for forming the pattern portion, a film having a specific color or a pattern may be attached to the outside of the edge of the transparent window after all of the cases are made of glass. In this case, since there is a restriction condition that a specific color or pattern should be attached to one side of the case made of glass, there are restrictions on diversification of aesthetic sense.
Alternatively, in another conventional technique for making the pattern portion, a method of separately fabricating a case outer portion that can be fitted to the transparent window, and then fitting the transparent window to the outer periphery of the case may be used. In this case, there is a disadvantage that the reliability of the mechanical coupling between the case outer portion and the transparent window may deteriorate.
The present invention provides a technique for manufacturing a user's device case that can provide a sense of beauty that was not provided in the prior art. The present invention also provides a technique for increasing the mechanical reliability of the thus manufactured user equipment case.
According to an aspect of the present invention, there is provided a method of manufacturing a case including a transparent portion passing light provided from a light emitting display device included in a user equipment and an opaque pattern portion formed along an edge of the transparent portion. The method includes the steps of: inserting a transparent member used as the transparent portion into a mold; Injecting a heated liquid opaque resin into a mold space formed in the mold; And cooling the injected opaque resin to form a pattern portion composed of the cooled opaque resin. At this time, protrusions or recesses are formed in a part of the surface of the transparent member exposed to the mold space so that the pattern unit and the transparent member can be mechanically coupled.
At this time, protrusions may be formed on a portion of the surface of the base transparent member that is exposed to the mold space.
Wherein the transparent portion includes the main body and the protrusion formed at an edge of the main body, wherein a width of a first point of the protrusion is greater than a width of a second point of the protrusion, Can be.
At this time, the transparent member may be glass.
At this time, the transparent member may be a synthetic resin, and a coating layer containing silicon dioxide may be formed on the user-side surface of the transparent member.
According to another aspect of the present invention, there is provided a method of manufacturing a case including a transparent portion passing light provided from a light emitting display included in a user's device and an opaque pattern portion formed along an edge of the transparent portion. The method includes the steps of: inserting an opaque member used as the pattern portion into a mold; Injecting a heated liquid transparent resin into a mold space formed in the mold; And cooling the injected transparent resin to form a transparent part composed of the cooled transparent resin. At this time, protrusions or recesses are formed in a portion of the surface of the opaque member exposed to the mold space so that the pattern portion and the transparent portion can be mechanically coupled.
At this time, a portion of the surface of the opaque member exposed to the mold space may have a recess.
At this time, the width of the first point of the concave portion may be smaller than the width of the second point deeper than the first point.
At this time, the case improving method may further include forming a coating layer on a user-side surface of the transparent portion.
According to another aspect of the present invention, there is provided a case including a transparent portion passing light provided from a light emitting display included in a user's device, and an opaque pattern portion formed along an edge of the transparent portion. In this case, the transparent portion includes a main body and a protrusion formed on an edge of the main body, a recess corresponding to the protrusion is formed at an edge of the pattern portion, and the transparent portion and the pattern portion are formed by a combination of the protrusion and the recess As shown in Fig.
The width of the first point of the protrusions may be smaller than the width of the second point of the protrusions farther than the first point. At this time, the pattern portion may have a ring-like shape.
According to the present invention, it is possible to provide a manufacturing technique of a user's device case that can provide a sense of beauty that was not provided in the prior art. Further, it is possible to provide a technique for increasing the mechanical reliability of the thus manufactured user equipment case.
