In order to facilitate input to a terminal and to provide a convenient user interface, an apparatus for enabling input using a touch method has been introduced. As a means for detecting a touch, a film (eg, an ITO film) including an electrode pattern may be used. The edges of the film are arranged with data lines connected to each pattern. In consideration of the appearance, the data line is opaque so as not to be seen from the outside. In addition, the functionally opaque portion defines the output area of the display module. As the opaque portion becomes wider, the output area of the display module appears smaller than the size of the entire portable terminal.

The present invention has been made in view of the above, and by reducing the width of an opaque portion (hereinafter referred to as a bezel portion) defining a display area in mounting a window in which a conductive film is integrated. Its technical purpose is to ensure a relatively wide display area.

In order to realize the above object, a portable terminal according to the present invention includes a case having a through-window configured to view a display unit installed therein; And a window assembly mounted to the through-window, wherein the window assembly comprises: a light transmitting base; A first conductive film disposed on an upper surface of the base; A second conductive film disposed on the first conductive film and configured to sense a touch in combination with the first conductive film; An adhesive tape disposed between the first conductive film and the second conductive film and sealing edge portions of the first conductive film and the second conductive film; And a protective film disposed on an upper portion of the second conductive film and having an opaque bezel formed on an edge thereof to define an output area of the display unit, wherein the protective film has a predetermined width (a width) from an edge of the conductive films. It is formed smaller than the conductive films to be disposed inward as W), the edge portion of the conductive films is configured to be supported by being locked to the inside of the case.

As an example related to the present invention, the first conductive film and the second conductive film may be configured to operate in a pressure manner.

The bezel part may have a width d starting from an edge of the protective film and extending to at least a portion where an inner edge line of the adhesive tape is located.

According to the mobile terminal according to the present invention configured as described above, since the edge portions of the conductive films with the non-transparent electrode line are configured to be covered by the case, at least the width of the bezel portion to cover the adhesive tape and the electrode line is required. In the conventional case, the width of the bezel portion can be significantly reduced. Therefore, not only the degree of freedom in design, but also a portable terminal having the same size, there is an advantage that the display can be enlarged.

2 is a front perspective view of an example of a mobile terminal or a mobile terminal according to the present invention;

The disclosed portable terminal 100 has a terminal body 101 in the form of a bar. However, the present invention is not limited thereto, and is applicable to various structures such as a bar type consisting of only one body, or a slide type, a folder type, a swing type, a swivel type in which two or more bodies are coupled to be relatively movable.

Referring to FIG. 3, a second camera 125 may be additionally mounted on the rear surface of the terminal body 101. The second camera 125 may be a camera having a photographing direction substantially opposite to that of the first camera 121 disposed on the front surface of the terminal body 101 and having different pixels from the first camera 121.

For example, the first camera 121 has a low pixel so that the user's face is photographed and transmitted to the counterpart in case of a video call, and the second camera 125 photographs a general subject and does not transmit it immediately. In many cases, it is desirable to have a high pixel. These cameras 121 and 125 may be installed in the terminal body in a rotatable or pop-up manner.

4 is an exploded perspective view of the portable terminal of FIG. 2. According to FIG. 4, the front case 102 is formed with a through window 102a so as to see the display unit 151 disposed therein. Inside the through-window 102a, a window assembly 200 in which a means for protecting the display unit 151 and enabling touch input is integrally assembled.

The through window 102a has at least the same size as the display 150 so that the display 151 is not covered. However, more precisely, the through window 102a has a size slightly smaller than that of the window assembly 200, and the window assembly 200 is assembled in a state of being disposed inside the front case 102.

5 is a partial cross-sectional perspective view showing an enlarged edge portion of the window assembly of FIG. 3 as an example related to the present invention, and FIG. 6 is a cross-sectional view of the portable terminal in which the window assembly is mounted.

According to these figures the window assembly 200 comprises several layers. These layers are in order from the base 230 at the bottom to the first conductive film 225, the second conductive film 221, and the protective film 210.

The base 230 serves to support the conductive films 225 and 221 and the protective film 210, and is formed to cause as little deformation as possible from touch operation or impact and provide sufficient rigidity. The light transmissive base 230 may be formed of glass, tempered glass, plastic, or tempered plastic. In particular, when formed of tempered glass, a thin and high rigidity can be expected. The base 230 is formed to be translucent so that the light of the display 151 can pass therethrough. Here, 'translucent' is a concept including translucent, and may further include an anti-reflection paint or coating to lower the reflectivity.

The first conductive film 225 is attached to the upper surface of the base 230 by the first adhesive layer 228. The first adhesive layer 228 is formed to be translucent so that light of the display 151 is not blocked.

The first conductive film 225 and the second conductive film 221 each include a transparent electrode pattern so as to sense a touch. As such an example, the first conductive film 225 and the second conductive film 221 may be formed in the form of a film on which indium tin oxide (ITO) is deposited. The electrode patterns are collected at edge portions of the first conductive film 225 and the second conductive film 221 and connected to the circuit board (not shown) by a connecting means such as a flexible PC 401 (see FIG. 4). Since the electrode pattern collected at the edge portion (hereinafter referred to as 'electrode line') is formed of an opaque metal such as copper foil, this portion needs to be masked so as not to be exposed from the outside.

The first conductive film 225 and the second conductive film 221 are formed to detect a pressure type touch. To this end, a gap 224 is formed between the first conductive film 225 and the second conductive film 221, and a spacer 226 is included to maintain the gap 224. The gap 224 may be filled with a medium (eg, liquid crystal) having a refractive index similar to that of the first conductive film 225 and the second conductive film 221 so as to reduce the difference in refractive index.

When there is a touch having a predetermined pressure or more on the protective film 210, the second conductive film 221 of the portion is deformed to be in contact with the first conductive film 225. The position of the contact point is obtained by using the measured current and the resistance value of the portion, and the input content by the touch becomes output information of the display 151 corresponding to the determined position. However, the present invention may be applied to the capacitive touch screen as an example applied to the above-described static pressure (resistive).

An edge portion of the first conductive film 225 and the second conductive film 221 is attached to the adhesive tape 223 for sealing the foreign matter to prevent penetration into the air gap 224. Adhesive tape 223 may be used that is attached to the adhesive on both sides.

The protective film 210 is attached to the upper surface of the second conductive film 221 by a light-transmissive adhesive layer, and is a portion where touch is substantially made. 4 and 5, the protective film 210 is formed smaller than the conductive films 225 and 221 so that the edge thereof is disposed inwardly by a predetermined width W from the edges of the conductive films 225 and 221.

An opaque bezel portion 215 is formed at an edge portion of the protective film 210 to define an area of the display unit 151. The bezel part 215 is implemented by a method of printing an opaque dye such as metal color or black, and becomes a boundary of the display part 151 during operation of the display part 151. The bezel part 215 is an insoluble area that the display unit 151 cannot output. As the bezel part 215 is wider, the display unit 151 may be relatively smaller, so the bezel part 215 Reducing the breadth may be the key.

According to FIG. 6, edge portions of the conductive films 225 and 221 are supported by being locked inside the front case 102. That is, the front case 102 has a locking jaw 102b for engaging the edges of the conductive films 225 and 221, and the electrode line and the adhesive tape 223 of the conductive films 225 and 221 are caught. It is naturally covered by the jaw 102b.

Thus, in the conventional case where at least the width of the bezel portion covering the adhesive tape 223 and the electrode line was required (the width of the bezel portion covering the electrode line and the adhesive tape in such a manner that the window assembly is assembled directly from the top of the front case). In this regard, the width of the bezel portion 215 can be significantly reduced. In particular, since the engaging jaw portion 102b of the front case 102, which covers the edges of the conductive films 225 and 221, can design a curved edge as a whole, the bezel portion 215 is almost the front of the mobile terminal 100. It is located at the edge of. Therefore, the display unit 151 can be obtained with a relatively large effect, and even if the portable terminal has the same size, the display unit can be enlarged. In addition, since the window assembly 200 is assembled inside the front case 102, the lifting phenomenon of the window assembly 200 is prevented.

The above-described portable terminal is not limited to the configuration and method of the embodiments described above, but the embodiments may be configured by selectively combining all or some of the embodiments so that various modifications can be made. .
