[ The image frame may be stored in the memory 160 or transmitted to the outside through the wireless communication unit 110. [ More than two cameras 121 may be provided depending on the use environment.

The microphone 122 processes the sound signal input from the outside in the communication mode, the recording mode, the voice selection mode, and the like as electrical voice data. The voice data processed by the microphone 122 in the communication mode can be converted into a form that can be transmitted to the mobile communication base station through the mobile communication module 112 and output.

The touch sensor may be configured to convert a pressure applied to a specific portion of the display portion 151 or a change in capacitance generated at a specific portion of the display portion 151 into an electrical input signal. The touch sensor may be configured to detect a touch pressure as well as a touched position and area.

When the touch sensor and the display unit 151 have a mutual layer structure, the display unit 151 can be used as an input device in addition to the output device. The display unit 151 may be referred to as a 'touch screen'.

If there is a touch input via the touch screen, signals corresponding thereto are sent to a touch controller (not shown). The touch controller processes the signals transmitted from the touch sensor, and then transmits data corresponding to the processed signals to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched.

In the case where the touch screen is electrostatic, it can be configured to detect the proximity of the sensing object by a change of the electric field along the proximity of the sensing target. Such a touch screen may be classified as proximity sensor 141. [

The proximity sensor 141 refers to a sensor that detects the presence or absence of an object to be sensed without mechanical contact using an electromagnetic force or infrared rays. The proximity sensor 141 has a longer life than the contact type sensor and its utilization is also high. Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor.

Hereinafter, for convenience of explanation, a proximity action is referred to as " proximity touch " while an object to be sensed does not touch the touch screen, and an action of touching the sensing object on the touch screen is called & touch ".

The proximity sensor 141 detects the presence or absence of a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, The information corresponding to the presence / absence of proximity touch and the proximity touch pattern can be output to the touch screen.

Hereinafter, a method of processing user input to the mobile terminal 100 will be described.

The user input unit 130 is operated to receive a command for controlling the operation of the mobile terminal 100, and may include a plurality of operation units. The operating units may also be referred to as manipulating portions and may be employed in any manner as long as they are operated in a tactile manner by the user's tactile sense.

Various kinds of time information can be displayed on the display unit 151. [ Such visual information can be displayed in the form of letters, numbers, symbols, graphics, icons, and the like, and can be formed as a three-dimensional stereoscopic image. At least one of a character, a number, a symbol, a graphic, and an icon may be displayed in a predetermined arrangement for inputting time information, thereby being implemented as a keypad. Such a keypad may be referred to as a so-called " soft key ".

The display unit 151 may operate as an entire area or may be divided into a plurality of areas and operated. In the latter case, the plurality of areas can be configured to operate in association with one another. For example, an output window and an input window may be displayed on the upper and lower portions of the display unit 151, respectively. The output window and the input window are areas allocated for outputting or inputting information, respectively. In the input window, a soft key with a number for inputting a telephone number may be output. When the soft key is touched, the number corresponding to the touched soft key is displayed in the output window.

One function of the mobile terminal 100 may be executed in response to a case where the display unit 151 and the touch pad are touched together within a predetermined time range. In the case of being touched together, there may be a case where the user clamps the main body of the mobile terminal 100 using the thumb and index finger. At this time, one function of the mobile terminal 100 to be executed may be activation or deactivation for the display unit 151 or the touch pad, for example.

On the other hand, as the mobile terminal 100 is improved in performance, the battery consumption of the mobile terminal 100 is rapidly increasing. However, the user wants not only to improve the performance of the mobile terminal 100 but also to use the mobile terminal 100 for a longer time. Therefore, in order to satisfy the needs of these users, research on wireless charging technology continues. Accordingly, a method for wirelessly charging the mobile terminal 100 using various payment methods is considered.

Accordingly, hereinafter, a mobile terminal 100 capable of wireless charging using various payment means and a control method thereof will be described with reference to the accompanying drawings.

2 is a flowchart illustrating an embodiment of a mobile terminal 100 (see FIG. 1) according to the present invention. The mobile terminal 100 includes a power receiver 191 (see FIG. 1), a wireless communication unit 110 (see FIG. 1), and a controller 180 (see FIG. 1).

Referring to FIG. 2, first, a step (S110) of transmitting user information to a server or a wireless charging pad is performed.

In embodiments of the present invention, the visual information may be displayed in an area in which a user interface is displayed on the display unit 151 (see FIG. 1) in the form of a text message or a graphic message. In addition, a pop-up window including visual information may be displayed on the display unit 151.

The wireless charging pad may first detect the mobile terminal 100. The wireless charging pad may perform an analog ping step and a digital ping step. More specifically, by changing the current value flowing in the coil of the wireless charging pad in the analog ping step, the wireless charging pad can detect that the mobile terminal 100 exists on the wireless charging pad. Thereafter, the wireless charging pad may transmit a minimum power to the mobile terminal 100 to start communication with the mobile terminal 100 in the digital ping step. As the mobile terminal 100 receives power from the wireless charging pad, the mobile terminal 100 may detect the wireless charging pad. In this case, the wireless charging pad may request user information from the mobile terminal 100, and the mobile terminal 100 may transmit user information to the wireless charging pad.

On the other hand, the mobile terminal 100 may first detect the wireless charging pad. The mobile terminal 100 may detect the wireless charging pad by receiving an ID of the wireless charging pad through wireless communication. In this case, the mobile terminal 100 may directly transmit user information to the wireless charging pad.

The wireless communication unit 110 may transmit user information to a server or a wireless charging pad. Specifically, the wireless communication unit 110 uses the reserved packet of the identification & configuration packet according to the Wireless Power Consortium (WPC) communication standard to obtain the ID of the mobile terminal 100 as a server or a wireless charging pad. Can be sent to.

Meanwhile, in addition to the ID of the mobile terminal 100, the wireless communication unit 110 may transmit at least one of user's age, gender, occupation, address, and interest information to a server or a wireless charging pad as user information.

In this case, the wireless communication unit 110 may perform wireless communication with the wireless charging pad using at least one of Near Field Communication (NFC), Bluetooth Communication, Infrared Communication, and ZigBee Communication. In addition, the wireless communication unit 110 may perform wireless communication with a server using at least one of Wi-Fi, 3G network, and 4G network.

 Next, step S120 of receiving point information related to user information from a server or a wireless charging pad is performed.

In detail, the mobile terminal 100 may perform payment through external magnetic field communication with an external device. Here, the external device may be any external device, sticker, tag, card, or the like. Specifically, the external device is equipped with a communication tag for payment. The mobile terminal 100 receives tag information from a communication tag mounted on an external device. In this case, the communication tag may be referred to as an NFC tag. On the other hand, the external device may include a wireless charging pad.

When the mobile terminal 100 performs payment through adjacent magnetic field communication, at least one of payment information and point accumulation information may be transmitted to a server or a network. In addition, the mobile terminal 100 may receive at least one of payment approval information, accumulated point information, and remaining point information from a server or a network. In this case, at least one of payment approval information, accumulated point information, and remaining point information may be displayed on the display unit 151.

Meanwhile, even when the mobile terminal 100 does not make a payment, when a control command for receiving point information is detected, the mobile terminal 100 may receive point information. For example, when the mobile terminal 100 and the wireless charging pad are adjacent to each other, the mobile terminal 100 may receive point information. In addition, even when a menu for receiving point information displayed on the display unit 151 of the mobile terminal 100 is selected, the mobile terminal 100 may receive the point information.

Thereafter, a menu for receiving a selection of whether to receive power is displayed (S130) and at least one of the received power amount information and the point deduction information according to the received power amount information so that the points are subtracted based on the received power amount is stored in the server. Or step S140 is transmitted to the wireless charging pad.

In detail, the display unit 151 may display a menu for selecting whether to receive power using the point information. The controller 180 may display guide information on point deduction along with a menu on the display unit 251. Here, the menu may be displayed in the form of a text message or a graphic message in an area where the user interface is displayed on the display unit 151. In addition, a pop-up window including a menu may be displayed on the display unit 151.

Next, in step S140, the power receiver 191 is controlled to wirelessly receive power from the wireless charging pad based on the selection of the menu.

The power receiver 191 is configured to receive power (wireless power) wirelessly transferred from the wireless charging pad. In this case, the wireless power may be transmitted using a wireless power transmission method such as an inductive coupling method, a resonance coupling method, or a mixture thereof.

The power receiver 191 may include a component required for receiving wireless power according to the wireless power transmission method described above. For example, the power receiver 191 may include a coil for receiving wireless power in the form of a magnetic field or an electromagnetic field having a vibrating characteristic.

In detail, the power receiver 191 may be a component according to an inductive coupling method, and may include a secondary coil that induces a current by a changing magnetic field. In addition, the power receiver 191 is a component according to a resonance coupling method, and may include a coil and a resonance circuit for generating a resonance phenomenon by an electromagnetic field having a specific resonance frequency.

The power receiver 191 may charge the battery using power supplied or transmitted from the wireless charging pad. In this case, the power receiver 191 may control the charging voltage, the charging current, the charging speed, and the like.

When a control command for receiving power is detected using the point information, the controller 180 may control the power receiver 191 to wirelessly receive power from the wireless charging pad.
