Description

Protection cover of portable terminal made by touch screen to curved surface and it's manufacture method}

The present invention relates to a protective cover of a portable terminal having a curved touch screen and a method of manufacturing the same, and more particularly, to completely attach the protective glass to a touch screen of a portable terminal body having a curved touch screen. The present invention relates to a protective cover of a portable terminal having a curved touch screen and a method of manufacturing the same.

In general, portable terminals, which allow a large number of users to transmit and receive a series of information using a constant frequency band, have various ways to revival consumer needs and contribute to convenience in use as electronic and communication technologies are rapidly evolving. The situation is being developed, and various kinds thereof are mobile phones, electronic dictionaries, navigation, iPhone, smart phones, and the like.

Recently, portable terminals have been operated as a touch screen using a finger without a dial pad, and recently, smart devices such as tablet PC (Tablet Personal Computer) iPad and iPhone and Samsung's Galaxy Tab, etc. This continues to be released.

As described above, the portable terminal is exposed to the outside of the touch screen according to the application of the touch method, and the breakage of the touch screen frequently occurs due to external impact or friction. As a result, scratches and the like frequently occur on the surface of the touch screen liquid crystal display device.

In order to solve this problem, the film is attached to the touch screen of the portable terminal using a pressure-sensitive adhesive. The film also has a problem that scratches are generated on the surface of the film due to physical properties, and thus need to be replaced after a certain time of use.
