The main body has a display for outputting time information. The window is mounted to the body to cover the display with a plurality of layers. The window is also configured to sense a touch input. The conductive lines are formed on at least one surface of the layers to calculate a touched position at the touch input. In order to transmit and receive wireless electromagnetic waves to the at least one surface, the antenna pattern is formed with conductivity. The conductive lines and the antenna pattern may be formed by coating a conductive material on the surface. The touch input may be restricted while the antenna pattern is transmitting / receiving wireless electromagnetic waves.

The connection circuit may be formed of a flexible circuit board (FPCB), and may be connected to the window by a pin.

According to another aspect of the present invention, ends of the conductive lines are connected to electrodes formed on the surface, and the antenna pattern is formed to be spaced apart from the electrodes. The conductive lines may be disposed in a lattice shape within a rectangular region defined by the electrodes, and the antenna pattern may be arranged to extend in correspondence with at least a portion of the periphery of the region. An insulating portion may be disposed between the antenna pattern and the electrodes.

According to another aspect of the present invention, the antenna pattern is at least one electrode connected to the conductive lines. In this case, a switching unit for selectively activating the electrode in association with any one of the touch input mode and the wireless electromagnetic wave transmission / reception mode is further provided.

As a result, it is possible to simultaneously coat the electrode 232 and the antenna pattern 250 as a conductive material on one surface of the second conductive layer 230.

The antenna pattern 250 is formed adjacent to the electrode 232. Specifically, the antenna pattern 250 may be formed to extend in parallel with the electrode 232 along the outer periphery of the electrode 232. By a spaced distance between the antenna pattern 250 and the electrode 232, they are electrically insulated from each other.

According to this configuration, the window 151a capable of touch input also functions to support the antenna pattern 250. FIG. By using the antenna pattern 250, it is possible to receive an FM radio broadcast or a DMB broadcast.

In the above description, the conductive lines 221 and 231 are formed in the first and second conductive layers 220 and 230, respectively. However, the conductive lines may be arranged in a lattice form in one conductive layer. This can be done by inserting an insulating material at the intersection of the conductive lines. In this case, the electrodes 222 and 232 will also be formed in one conductive layer.

In this case, the window 151a may not include at least one of the plurality of layers 210, 220, 230, Alternatively, the window 151a may include additional layers in addition to the plurality of layers 210, 220, 230,

6 is a perspective view illustrating a modification of the second conductive layer 230 of FIG.

Referring to FIG. 6, an antenna pattern 250 'is formed on the second conductive layer 230' to surround the second electrode 232 as a whole. Thus, the antenna pattern 250 'has a loop shape. The loop antenna pattern 250 'can transmit and receive wireless electromagnetic waves for implementing a function of a traffic card that communicates with a reader installed in a bus or a subway station.

During the operation of the antenna pattern 250 ', the touch input to the window 151a may be linked to the transmission / reception of the electromagnetic wave using the antenna pattern 250'. However, if it is assumed that the window 151a is touched unintentionally by contact with the reader during the use of the traffic card function, if the antenna pattern 250 'touches through the window 151a during the wireless electromagnetic wave transmission / .

An insulating portion 280 is formed between the antenna pattern 250 'and the second electrode 232. The insulating portion 280 is formed by applying an insulating material between the antenna pattern 250 'and the second electrode 232, unlike the previous embodiment. The insulating portion 280 may be useful when the antenna pattern 250 'and the second electrode 232 are in close contact with each other.

7 is a perspective view illustrating a second conductive layer 230 "according to another embodiment of the present invention.

In the present embodiment, the second electrode 232 serves as an electrode for calculating the position of the touch input, and functions as an antenna pattern. In this case, the signal line 233 not only connects the second electrode 232 to the control unit 180, but also connects the antenna pattern to the control unit 180.

If a loop antenna pattern is to be implemented, a pair of conductive parts constituting the second electrode 232 may be connected. The connection line 290 connecting them is also formed of a conductive material and may be coated on the second conductive layer 230 'at the same time as the second electrode 232.

8 is a conceptual diagram for explaining a control method for the window 151a including the second conductive layer 230 "in FIG.

Referring to FIG. 8, four electrodes 231 and 232 (see FIG. 5) are connected to the switching unit 185 through four pins 271. The switching unit 185 is controlled by the control unit 180.

In the touch input mode in which the electrodes 231 and 232 operate in conjunction with the conductive lines 221 and 231 to calculate the position of the touch input, the switching unit 185 switches the electrodes 231 and 232 to touch To the recognition module 135. The touch recognition module 135 is also controlled by the control unit 180.

When the touch input mode is deactivated and the wireless electromagnetic wave transmission / reception mode based on the antenna pattern is desired to be implemented, the switching unit 185 blocks the connection with the touch recognition module 135. Instead, the switching portion 185 allows the electrodes 231 and 232 to be connected to at least one of the various communication modules 111 and 114 (see FIG. 1). For the traffic card function, the second electrode 232 may be connected to the short-range communication module 114 in the form of a loop by the connection line 290. The first electrode 231 may be connected to the broadcast receiving module 111 for radio reception or DMB broadcast reception.

FIG. 9 is a perspective view illustrating a state of use of the portable terminal 100 having the switching unit 185 of FIG.

Referring to FIG. 5, the touch input mode and the wireless electromagnetic wave transmission / reception mode can be selectively activated by the operation of the switching unit 185 by one operation of the portable terminal 100. For example, the sensing unit 140 having the gyro sensor may sense the arrangement state of the portable terminal 100 and recognize the command for the operation of the switching unit 185.

Alternatively, as illustrated in the figure, a command for the operation of the switching unit 185 may be input by operating a key such as the second operating unit 132. [ For example, when the second operation unit 132 is operated in the electromagnetic wave transmission / reception mode, the touch input becomes possible through the window 151a. The touch input can be performed while the second operation unit 132 is operated, and when the operation to the second operation unit 132 is canceled, the original electromagnetic wave transmission / reception mode can be returned.

Alternatively, when one of the above two modes is changed to another one by a one-time operation on the second operation unit 132, and when there is a subsequent operation on the second operation unit 132, .

Alternatively, when the user touches and inputs a broadcast reception or the like in the menu M output from the display 151b, the switching unit 185 switches the touch input mode to the electromagnetic wave transmission / reception mode as the broadcast is received Lt; / RTI >

The situation in which one of the above two modes by the operation of the switching unit 185 is operated can be confirmed as the display 151b outputs the display icon 155. [ For example, if the touch input mode is activated, the display 151b may display the T (T) initials associated with the touch.

10 is a conceptual diagram showing another modification of FIG.

In this modified example, not all of the connection circuits 260 are connected to the switching unit 185 '. Only one of the connection circuits 260 is connected to the touch recognition module 135 via the switching unit 185 '.

As a result, only one of the four conductive portions constituting the first and second electrodes 222 and 232 functions as an antenna pattern. In this case, the one part is selectively connected to the broadcast receiving module 111 by the switching unit 185 'to receive the FM broadcast or the DMB broadcast.
