Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

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. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The photosensor can be laminated to the display element, which is arranged to scan the motion of the object to be sensed proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The wireless charging may be implemented by a magnetic induction method or a resonance method (magnetic resonance method).

The rear cover 103 is configured to be coupled to the rear case 102 so as to cover the battery 191 to restrict the release of the battery 191 and to protect the battery 191 from external impact and foreign matter . When the battery 191 is detachably attached to the terminal body, the rear cover 103 may be detachably coupled to the rear case 102.

The mobile terminal 100 may be provided with an accessory that protects the appearance or supports or expands the function of the mobile terminal 100. [ One example of such an accessory is a cover or pouch that covers or accommodates at least one side of the mobile terminal 100. [ The cover or pouch may be configured to interlock with the display unit 151 to expand the function of the mobile terminal 100. Another example of an accessory is a touch pen for supplementing or extending a touch input to the touch screen.

As shown in FIG. 1A, a mobile terminal according to the present invention includes Bluetooth ™, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, NFC Field Communication), and Wireless USB (Wireless Universal Serial Bus).

Among them, the NFC module provided in the mobile terminal supports the non-contact type short-range wireless communication between the terminals at a distance of about 10 cm. The NFC module may operate in either a card mode, a reader mode, or a P2P mode. In order for the NFC module to operate in the card mode, the mobile terminal 100 may further include a security module for storing card information. Here, the security module may be a physical medium such as a UICC (e.g., a SIM (Subscriber Identification Module) or a USIM (Universal SIM)), a Secure micro SD and a sticker, or a logical medium For example, embeded SE (Secure Element)). Data exchange based on SWP (Single Wire Protocol) can be made between NFC module and security module.

When the NFC module is operated in the card mode, the mobile terminal can transmit the stored card information to the outside such as a conventional IC card. Specifically, if the mobile terminal storing the card information of the payment card such as a credit card or a bus card is brought close to the fare payment machine, the mobile local payment can be processed, and the mobile terminal storing the card information of the access card can be accessed If you are close to the time, the approval process for access may begin. Cards such as credit cards, transportation cards, and access cards are mounted on the security module in the form of an applet, and the security module can store card information on the mounted card. Here, the card information of the payment card may be at least one of a card number, balance, and usage details, and the card information of the access card may include at least one of a name, a number (e.g., It can be one.

When the NFC module is operated in the reader mode, the mobile terminal can read data from an external tag. At this time, the data received from the mobile terminal by the tag may be coded into a data exchange format (NFC Data Exchange Format) defined by the NFC Forum. In addition, the NFC Forum defines four record types. Specifically, the NFC forum defines four RTDs (Record Type Definitions) such as Smart Poster, Text, Uniform Resource Identifier (URI), and General Control. If the data received from the tag is a smart poster type, the control unit executes a browser (e.g., an Internet browser), and if the data received from the tag is a text type, the control unit can execute the text viewer. When the data received from the tag is a URI type, the control unit executes the browser or makes a telephone call, and if the data received from the tag is a general control type, it can execute appropriate operations according to the control contents.

When the NFC module is operated in a peer-to-peer (P2P) mode, the mobile terminal can perform P2P communication with another mobile terminal. At this time, LLCP (Logical Link Control Protocol) may be applied to P2P communication. For P2P communication, a connection can be created between the mobile terminal and another mobile terminal. At this time, the generated connection can be divided into a connectionless mode in which one packet is exchanged and terminated, and a connection-oriented mode in which packets are exchanged consecutively. Through P2P communications, data such as business cards, contact information, digital photos, URLs in electronic form, and setup parameters for Bluetooth and Wi-Fi connectivity can be exchanged. However, since the usable distance of NFC communication is short, the P2P mode can be effectively used to exchange small-sized data.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

FIG. 2 is a flowchart of a method of controlling a mobile terminal according to a first embodiment of the present invention, and FIGS. 3 to 9 are views for explaining a method of controlling the mobile terminal according to the first embodiment of the present invention. Hereinafter, it is assumed that the fingerprint recognition unit is formed on the rear power button. However, the fingerprint recognition unit can be formed in at least one area of the front power button or the display unit as well as the rear power button.

Referring to FIG. 2, the controller 180 of the mobile terminal acquires a fingerprint through the fingerprint recognition unit (S110), and may detect the movement of the terminal while performing fingerprint authentication (S120).

Specifically, the controller 180 may obtain fingerprints using a fingerprint recognition unit formed on at least one of the rear face, the front power button, and the display unit 151. [ The control unit 180 determines whether the fingerprint acquired through the fingerprint recognition unit includes feature points that can be distinguished from others, and performs fingerprint authentication by comparing the feature points of the user registered in advance with the feature points of the obtained fingerprint. If the fingerprint acquired through the fingerprint recognition unit does not include the feature point, the control unit 180 can determine that the fingerprint is a general touch input.

The controller 180 can detect the movement of the terminal while the fingerprint authentication is performed. At this time, the movement of the terminal means a change of the position of the terminal changed from the initial terminal position to the time when the fingerprint authentication is completed when the fingerprint is input, and it can be determined whether the movement of the terminal is out of the set displacement range. That is, when the movement of the terminal is included in the set displacement range, the controller 180 determines that the movement is caused by the operation input of the terminal, and if the movement of the terminal is out of the set displacement range, It can be determined that the terminal is a movement for contacting the merchant terminal.

If the fingerprint authentication is successful (Yes), the control unit 180 can select the operation mode of the terminal as the first mode (S150) if the movement of the terminal does not deviate from the set displacement range (No). Here, the first mode represents an operation mode for controlling the display unit 151 to turn on the power of the display unit 151 and release the locked state.

If the fingerprint authentication is successful (YES), the control unit 180 can select the operation mode of the terminal as the second mode (S160) when it is determined that the movement of the terminal is out of the set displacement range (YES). Here, the second mode represents an operation mode for controlling payment to be performed using preset payment card information. The control unit 180 can perform settlement without turning on the power of the display unit 151 when the operation mode of the terminal is selected as the second mode.

If the similarity is less than the reference percentage, the controller 180 selects the first mode. When the similarity is less than the reference percentage, the controller 180 selects the second mode You can choose. An operation pattern for contacting the mobile terminal 100 to the merchant terminal 500 for payment may be preset and a first mode or a second mode may be selected by comparing with the movement pattern of the detected terminal.

The control unit 180 controls the display unit 151 to turn on the power in the second mode when fingerprint authentication is performed after receiving a specific input to the display unit 151 or the back frame 103 of the terminal .

If the control unit 180 receives an input to the first or second operation unit 123a or 123b formed in the terminal after selecting the second mode, the controller 180 can change the preset payment card to another payment card. At this time, the controller 180 may provide the sound or haptic feedback set corresponding to the changed payment card.

The control unit 180 may control the display unit 151 to turn on the power to display the settlement result or to output the settlement result through the sound output unit 152 when the settlement is completed in the second mode.

The controller 180 further determines whether the terminal is in a gripped state, controls the fingerprint authentication in a state where the terminal is gripped, and selects the second mode when the terminal moves beyond the set displacement range.

If the fingerprint authentication fails (No), the control unit 180 can maintain the operation mode of the terminal to the previous state (S170). For example, if the fingerprint authentication fails in the standby state, the controller 180 can maintain the operation mode of the terminal in the standby state.

The fingerprint recognition unit may be formed on the power button on the front or rear surface of the terminal and the power button may be formed in a dual structure to receive two inputs that are classified according to the applied pressure. When receiving the input of the first pressure for the power button formed in the dual structure, the controller 180 determines that the signal is for turning on the power of the display unit 151, and when receiving the input of the second pressure, As shown in FIG.

3 to 9, the control method of the mobile terminal according to the first embodiment of the present invention will be described in detail.

Referring to FIG. 3, the controller 180 of the mobile terminal can detect movement of the terminal 100 during fingerprint authentication by acquiring fingerprints through the power buttons P1 and P2.

The control unit 180 can select the operation mode of the terminal 100 as the first mode when the movement of the terminal 100 is within the set displacement range. Here, the first mode refers to an operation mode in which the display unit 151 is powered on and the locked state is released.

When the fingerprint is input through the rear button P2, the controller 180 compares the inputted fingerprint with the fingerprint registered in advance, and if the fingerprint matches the minutiae, it can be determined that the fingerprint authentication is successful.

If the fingerprint authentication is successful, the controller 180 turns on the power of the display unit 151 and releases the locked state to display the home screen on the display unit 151. [

4, the controller 180 of the mobile terminal can detect the movement of the terminal 100 out of the set displacement range during the fingerprint authentication by acquiring the fingerprint through the power buttons P1 and P2 .

When the controller 180 detects the movement of the terminal 100 toward the franchise terminal 500, that is, when the controller 100 determines that the movement of the terminal 100 is out of the reference displacement range, When the signal of the merchant terminal 500 is received, the operation mode of the terminal 100 can be selected as the second mode. Here, the second mode means an operation mode in which settlement can be performed using a preset payment card.

Referring to FIG. 5, the controller 180 of the mobile terminal can output the settlement result when the second mode is selected and settlement is completed.

Specifically, when the settlement is completed in the second mode, the controller 180 outputs the vibration (a) through the vibration module of the terminal 100 or the notification (b) through the sound output unit 152 .

The control unit 180 can display the payment result on the display unit 151 by turning on the screen of the display unit 151 when the settlement is completed. Specifically, when the payment is completed, the control unit 180 turns on the display unit 151 to display the payment amount, payment time, payment details, etc. May be displayed on the display unit 151. [0156] FIG.

Or upon completion of payment, when the display unit 151 of the terminal 100 moves or approaches the viewing angle of the user, the screen of the display unit 151 is turned on to display the payment amount, payment time, May be displayed on the display unit 151. [0156] FIG.

6, when the second mode is selected, the control unit 180 of the mobile terminal uses a preset payment card. However, when receiving input to the first or second operation unit 123a or 123b, The set payment card can be changed to another payment card.

The control unit 180 may store a plurality of payment cards and may store a notification sound or a haptic effect fb corresponding to each payment card.

When the display unit 151 is operated in the second mode with the power of the display unit 151 turned off, the control unit 180 receives the input to the first or second operation unit 123a or 123b, . At this time, the control unit 180 may output the notification sound or the haptic effect fb corresponding to the changed payment card.

7, the controller 180 of the mobile terminal receives specific inputs I1 and I2 for the display unit 151 or the back frame 103 of the terminal, and when the fingerprint authentication is successful, 151 may be turned on to display at least one payment card on the display unit 151. [ Here, fingerprint authentication can be performed through the rear power button (P).

The specific input may be a double-touch input I1 for the display portion 151 or the back frame 103 of the terminal or an input I2 of the set pattern. Here, the set pattern may be divided into four quadrants and input in a set order for each quadrant, the display unit 151 or the rear frame 103 of the terminal.

When displaying at least one payment card on the display unit 151, the control unit 180 may display a predetermined payment card on the top of the display unit 151 or display the payment card in a central area of the display unit 151 . The control unit 180 may change the payment card displayed in the uppermost or central area through a drag input to at least one payment card.

The control unit 180 may tag the merchant terminal 500 and perform payment using a specific payment card in a state where a specific payment card is displayed on the uppermost or central area of the display unit 151. [

8, the fingerprint recognition unit may be formed on the power button P on the front or rear surface of the terminal 100, and the power button P may have different reception lengths l1 and l2 depending on the applied pressure. As shown in FIG.

When the power button P receives the input of the first pressure, when the first portion of the power button P is inserted into the receiving portion having the width W1 and the length is l1 and the input of the second pressure is received , The width of the power button P is extended to W2, and the second portion of the power button P can be inserted into the accommodating portion having the length l2.
