The wireless charging pad 200 can display the content generated by the execution of the application . ≪ / RTI > As a result, the wireless charging pad 200 can provide a function independent of the mobile terminal 100 to be charged, and convenience and usability can be improved.

Hereinafter, various embodiments in which the wireless charging pad 200 transmits at least one content to the mobile terminal 100 according to another embodiment of the present invention will be described with reference to FIGS. 5 and 6. FIG.

Referring back to FIG. 2, the short range communication unit 250 is configured to communicate with the mobile terminal 100 to transmit and receive data. At this time, the mobile terminal 100 transmitting and receiving data to and from the local communication unit 250 is not limited to the mobile terminal 100 charged through the wireless charging pad 200. The short-range communication unit 250 uses a short range communication technology such as Bluetooth, Radio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), ZigBee, And can communicate with the mobile terminal 100 in a short distance.

According to one embodiment, the wireless charging pad 200 may communicate with the mobile terminal 100 using the power transmitting module 220 in a short distance. In this case, the short-range communication unit 250 may be a power transmission module 220. That is, a separate independent local communication unit is not provided in the wireless charging pad 200, and the power transmission module 22 can function as a local communication unit. When the power transmitting module 220 functions as the short-range communication unit 250, the power transmitting module 220 partially changes the intensity of the magnetic field constituting the wireless power signal or puts a high-frequency signal for data transmission on the wireless power signal The specific data can be transmitted to the mobile terminal 100 together with the wireless power signal.

According to the present embodiment, the wireless charging pad 200 can communicate with the mobile terminal 100 without a separate independent module for the short range communication technology enumerated above. As a result, the wireless charging pad 200 can be configured to be compact while functioning to exchange data with the mobile terminal 100.

When the wireless charging pad 200 further includes the local communication unit 250 as described above, at least one of the contents stored in the wireless charging pad 200 is transmitted from the second touch screen 210 to the local communication distance Distance to the mobile terminal 100 located within a predetermined distance. According to one embodiment, content may be transmitted to the mobile terminal 100 when the mobile terminal 100 contacts the second touch screen 210 of the wireless charging pad 200.

The second control unit 240 may not operate the short range communication unit 250 when the measured distance is greater than the second distance.

As another example, the distance measuring unit may include a proximity sensor having a sensing range of the same size as the second distance. The proximity sensor may be disposed in an inner region of the housing 201 or near the second touch screen 210. Examples of the proximity sensor include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation Proximity sensors, capacitive proximity sensors, magnetic proximity sensors, and infrared proximity sensors. And when the second touch screen 210 is electrostatic, the proximity of the pointer is detected by a change of the electric field along the proximity of the pointer. In this case, the second touch screen 210 may be classified as a proximity sensor. In this case, when the proximity sensor senses the mobile terminal 100, the second controller 240 activates the short range communication unit 250 to transmit the content to the mobile terminal 100. The mobile terminal 100 is not detected in the proximity sensor, and the short range communication 250 is not operated.

According to another embodiment, the second distance may be zero. In this case, the short range communication unit 250 can communicate with the mobile terminal 100 only when the mobile terminal 100 contacts the second touch screen 210. In this embodiment, the wireless charging pad 200 may not include a separate distance measuring unit. The wireless charging pad 200 may sense the contact between the mobile terminal 100 and the second touch screen 210 by the touch pad of the second touch screen 210 and the second control unit 240 may detect that the contact is sensed The local communication unit 250 can be configured to operate only when the local communication unit 250 is operated.
