Mobile terminal

The present invention relates to a portable terminal, and more particularly, to a portable terminal that is easy to process.

A portable terminal is a portable device that is portable and has one or more functions of performing voice and video calls, inputting and outputting information, and storing data.

In the portable terminal implemented in the form of such a multimedia device, new attempts have been applied in various ways in terms of hardware and software to implement complex functions. Therefore, the mobile terminal may also function as a camera and also play a role of a music or video player.

Recently, portable terminals have a large display unit on the front and a number of products using a touch screen to which a touch window is applied. The touch screen refers to a display device that enables screen display and information input on one screen. The touch screen makes interactive and intuitive operations possible by touching the icons displayed on the display, so that the computer can be easily operated.

 However, the touch window of the portable terminal has a problem in that the production yield is lowered due to poor workability. In particular, in the case of the positive pressure touch window, there was a problem in that the machining of the inner working part is difficult. Therefore, there is a need for a method for improving the processability of the touch window when manufacturing a mobile terminal.

An object of the present invention is to provide a portable terminal including a touch window which is easy to process and the material cost is reduced.

In order to achieve the above object, the present invention provides a mobile terminal, which is capable of printing and forming a hole on a printed film, a transparent conductive film laminated on a part of the rear surface of the printing film, and a signal change occurs according to a touch, and a transparent conductive film on the back side. A first window layer, which is laminated and transparent, and a second window layer, which is laminated to another part of the rear surface of the printing film and is formed with parallel projections of the transparent conductive film and the first window layer, and wherein projections are fitted into holes in the printing film.

According to the present invention, the touch window can be easily processed to enable chamfer processing or round processing, the processing portion can be processed cleanly without being sharp, and uniform operation is possible when joining with a button or the like. Therefore, the production yield of the touch window can be improved. In addition, the use of a transparent conductive film is reduced, which is effective in reducing material costs.
