Description

  The present invention relates to a technique for attaching a protective film, and more particularly to a structure of a plurality of protective films for an electronic device.

  Currently, portable electronic devices such as smartphones and tablet computers that can be operated on the front have a large screen and a fine texture. In order to protect a portable electronic device from damage or scratches caused by collision or friction with an object, a protective film is usually attached to the surface of the portable electronic device. The transparent protective film is provided with an adhesive surface, and in order to protect the adhesiveness of the adhesive surface and avoid the adhesion of impurities, a release film is first laminated on the adhesive surface. The operation position on the front surface of the portable electronic device is the most common for the protective film application position.

  However, it is usually difficult to attach a single protective film perfectly. First, the protective film must be applied in a very short time. Also, when the release film on the adhesive surface is peeled off, a considerable amount of static electricity is usually generated and sucks up dust particles in the vicinity. The longer the time, the more dust particles will stick to the adhesive surface of the protective film. Since bubbles are formed in the process of adhering these dust particles, these bubbles between the protective film and the portable electronic device are difficult to remove.

  In addition, the release film is a single sheet and has the same size as the protective film. When the release film is peeled off, one end of the protective film can be attached to the heel side of the portable electronic device first, but when one side is put together, it becomes a small range deviation and difficult to judge with the naked eye. It can be seen that the user often deviates from the latter half of the process of pressing the protective film from the local area sequentially in the first half and pasting it on the portable electronic device. At this time, if there is a discontinuous surface structure of push buttons, speaker holes, or camera holes on the operation surface of the portable electronic device, a noticeable misalignment is formed in the opening on the protective film, affecting the aesthetics and functionality.
