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 adapted to scan the movement of the object to be detected 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.

In the following, various embodiments may be embodied in a recording medium readable by a computer or similar device using, for example, software, hardware, or a combination thereof.

2A and 2B are perspective views of an example of a mobile terminal 100 according to the present invention, viewed from different directions.

The disclosed mobile terminal 100 includes a bar-shaped terminal body. However, the present invention is not limited thereto, and can be applied to various structures such as a slide type, a folder type, a swing type, and a swivel type in which two or more bodies are relatively movably coupled.

The terminal body includes a case (a casing, a housing, a cover, and the like) which forms an appearance. In this embodiment, the case may be divided into a front case 101, a rear case 102 and a battery cover 103. [ A variety of elements are incorporated in the space formed between the front case 101 and the rear case 102. [ At least one middle case may be additionally disposed between the front case 101 and the rear case 102. [

The cases may be formed by injection molding a synthetic resin or may be formed to have a metal material such as stainless steel (STS), titanium (Ti), aluminum (Al), or the like.

The display unit 200, the sound output module 152a, the camera module 121, and the like may be disposed in the terminal body, mainly the front case 101. A microphone 122, a side input unit 132, an interface 160, and the like may be disposed on the side surfaces of the front case 101 and the rear case 102. [

The display unit 200 occupies most of the periphery of the front case 101. That is, the display unit 200 is disposed on the front surface of the terminal body to output time information. The sound output module and the camera module 121a may be disposed in an area adjacent to one end of both ends of the display unit 200 and the front input unit 131 may be disposed in an area adjacent to the other end.

The front input unit 131 may include a plurality of operation units as an example of the user input unit 130 (see FIG. 1). The operating units may also be referred to as manipulating portions and may be employed in any manner as long as the user is operating in a tactile manner with a tactile impression. In this embodiment, the front input unit 131 is constituted by a touch key. However, the present invention is not limited thereto, and the front input unit 131 may be provided with a fusible unit.

The side input unit 132 configured as another example of the user input unit 130 inputs a command such as a size adjustment of the sound output from the sound output module or a switch to the touch recognition mode of the display unit 200 Can receive.

In addition, the display unit 200 may form a touch screen together with the touch sensor. In this case, the touch screen may be a user input unit 130. Accordingly, the front input unit 131 is not provided on the front surface of the terminal. In this case, the mobile terminal 100 may be configured so that the input operation to the terminal body can be performed only through the display unit 200 and the rear input unit 133 described later.

The touch sensor is formed of a film having a touch pattern and is disposed between a window 151a and a display (not shown) on the back of the window 151a or a metal wire directly patterned on the back surface of the window 151a . Alternatively, the touch sensor may be formed integrally with the display. For example, the touch sensor may be disposed on a substrate of the display or inside the display.

In this case, the window 151a of the display unit 200 may be provided with an acoustic hole for emitting sound generated from the acoustic output unit. However, the present invention is not limited to this, and the sound may be configured to be emitted along an assembly gap (for example, a gap between the window 151a and the front case 101) between the structures. In this case, the appearance of the mobile terminal 100 can be made more simple because the hole formed independently for the apparent acoustic output is hidden or hidden.

The display unit 200 may further include an optical output unit for outputting light for notifying the user of an event. Here, examples of the event include a message reception, a call signal reception, a missed call, an alarm, a schedule notification, an e-mail reception, and reception of information through an application. The control unit 180 may control the light output unit to terminate the light output when the event confirmation of the user is detected.

In addition, in the present invention, the display unit 200 may be divided into two areas in one direction. In this case, the plurality of display areas 201 and 202 can be independently controlled, and power consumption can be reduced by selectively activating only one of the two areas, if necessary.

For example, the first area 201 of the display unit 200 may occupy most of the front surface of the mobile terminal 100 as a main screen for outputting general image information. The second area 202 of the display unit 200 may be arranged on the first area 201 side by side with an auxiliary screen for displaying status information of the mobile terminal 100 and the like.

The first region 201 and the second region 202 may be independently activated and deactivated. For example, when the user is not using the mobile terminal 100, the first area 201 is in the OFF state and the second area 202 is in the ON state. Thus, even when the mobile terminal 100 is not used, (Eg, date, time, etc.).

2A, the second region 202 is located at the upper end of the first region 201, but the present invention is not limited thereto, and the second region may be located at the lower end of the first region 201 Or both of the upper and lower ends are also possible. In another example, the second region 202 may be formed on one side or both sides of the first region 201.

Referring to FIG. 2B, a camera module 121b may be further mounted on the rear surface of the terminal body, that is, the rear case 102. The camera module 121b may have a photographing direction substantially opposite to the camera 121a (see FIG. 2a), and may be a camera having pixels different from the camera module 121a.

For example, the camera module 121a on the front side has low pixels so that it is easy to capture a face of a user in the case of a video call or the like and send it to the other party, and the camera module 121b on the rear side shoots a general object It is preferable to have a high pixel because it is often not transmitted. The camera modules 121a and 121b may be installed in the terminal body so as to be rotatable or pop-upable.

A flash (not shown) and a mirror (not shown) may be additionally disposed adjacent to the camera module 121b. The flash illuminates the subject when the subject is photographed by the camera module 121b. The mirror enables the user to illuminate the user's face or the like when the user intends to take a picture of himself / herself (self-photographing) using the camera module 121b.

An acoustic output module 152b may be additionally disposed on the rear surface of the terminal body. The rear acoustic output module 152b may implement a stereo function together with the front acoustic output module and may be used for implementing a speakerphone mode in a call.

A power supply unit 190 for supplying power to the mobile terminal 100 is mounted on the terminal body. The power supply unit 190 may be built in the terminal body or may be detachable from the outside of the terminal body.

According to the illustrated example, the rear input unit 133 may be disposed on the rear surface of the terminal body. The rear input unit 133 may be positioned adjacent to the camera module 121b, for example.

In addition, the rear input unit 133 is operated to receive a command for controlling the operation of the mobile terminal 100, and input contents may be variously set. For example, a command such as power on / off, start, end, scrolling, etc., control of the size of sound outputted from the sound output modules 152a and 152b, or the touch recognition mode of the display unit 200 A command such as switching can be inputted.

In another embodiment, a sensor for receiving a user's touch input and sensing a fingerprint of a user may be provided in one area of the rear input unit 133. Specifically, a touch sensor and a finger scan sensor are layered on the rear input unit 133 to recognize a fingerprint of a user finger touching or pushing the one area. Meanwhile, the finger scan sensor may be embedded in the display unit 200 or the user input unit 131 or 132.

The fingerprint recognition sensor may be activated depending on the state of the display unit 200. In this case, as described above, in the structure in which the display unit 200 is divided into the plurality of areas, if at least one of the first area 201 and the second area 202 is active, You can limit the sensor to be active.

Alternatively, the fingerprint recognition sensor may be configured to recognize the fingerprint of the user using different methods in the activated and deactivated states of the display unit 200. At this time, the different method may be related to the activation period of the fingerprint recognition sensor. More specifically, the fingerprint recognition sensor can recognize a fingerprint of a user applied to the fingerprint recognition sensor with different activation periods depending on whether the display unit 200 is activated or not.

In an embodiment, in a state in which the display unit 200 is inactivated, the fingerprint recognition sensor may be activated at a predetermined period. In this case, the specific period may be a period corresponding to a time greater than zero. In a state in which the display unit 200 is activated, the fingerprint recognition sensor can be always operated in an activated state. That is, in this case, the activation period of the fingerprint recognition sensor may be 0 or a period having a time very close to zero.

In addition, the rear input unit 133 may be implemented in a form capable of being rotated, and may be implemented in a form capable of 'proximity touch'. Also, the rear input unit 133 may include a plurality of keys. In this case, the keys may be formed in different shapes so that the plurality of keys can be easily identified only by the touch of the user's finger without rotating the terminal body.

Further, the rear input unit 133 may include a frame and a wheel key and a window mounted thereon. In this case, a frame (not shown) may be mounted to the case of the terminal body, for example, the rear case 102 as shown. Also, a wheel key (not shown) may be mounted on the frame, and may be formed to be exposed to the outside through a predetermined through hole.

In addition, the rear input unit 133 may be applied to a terminal having a display unit and a touch panel on both sides of a terminal body, and each display unit may be a transparent display, a stereoscopic display, a flexible display, Lt; / RTI >

Meanwhile, even when the screen is released from the standby state through the rear input unit 133, a separate input for releasing the locked state is required, so that user convenience is still deteriorated.

In order to solve such a problem, a method of releasing a locked state of a screen in the mobile terminal of the present invention including a user input unit and a sensor and a method of executing the application according to the present invention will be described with reference to FIGS. 3 and 13 .

In this regard, the locked state of the screen is a state in which the first screen is switched to the second screen when there is no input for a predetermined time or more by the user or by the system. On the other hand, the release of the lock state is performed by switching the second screen back to the first screen by the release input previously set by the user. Wherein the release input includes at least one of a pattern release input in accordance with whether or not the pattern matches the pre-stored pattern, a knock release input in accordance with whether or not the divided area on the display matches the touch, .

Also, the inactive state of the screen is a state in which the screen is kept in an off state until a return input for a screen activation by a user when there is no input for a predetermined time or more by the user or by the system. The return input is performed by pressing or touching the home button of the mobile terminal. At this time, the screen is switched to the active state by the return input, but the second screen is still maintained until the cancel input.

The controller 180 activates the fingerprint recognition sensor 145 to detect a fingerprint of a user contacting the button when the contact sensor 300 senses contact of the human body. If the fingerprint sensed by the fingerprint sensor 145 corresponds to the preset fingerprint, the controller 180 cancels the locked state.

As shown in FIG. 2, the display unit 200 may include a first region 201 and a second region 202. Meanwhile, FIG. 4 illustrates a method of setting a screen lock in a mobile terminal having a plurality of display areas according to an embodiment of the present invention.

In this regard, the first area 201 of the display unit 200 may occupy most of the front surface of the mobile terminal 100 as a main screen for outputting general image information. The second area 202 of the display unit 200 may be arranged on the first area 201 side by side with an auxiliary screen for displaying status information of the mobile terminal 100 and the like.

The first region 201 and the second region 202 may be independently activated and deactivated. For example, when the user is not using the mobile terminal 100, the first area 201 is in the OFF state and the second area 202 is in the ON state. Thus, even when the mobile terminal 100 is not used, (Eg, date, time, etc.).

2A and FIG. 4, although the second region 202 is shown as being located at the top of the first region 201, the second region is not limited thereto, and the second region may be located at the bottom of the first region 201 Or a structure that is located at both the upper end and the lower end is also possible. In another example, the second region 202 may be formed on one side or both sides of the first region 201.

For example, according to (b) of FIG. 4, the releasing method includes a fingerprint input, a pattern cancellation input according to whether or not the pattern matches the pre-stored pattern, and a knock cancellation input .

4 (c), when the releasing method includes both the fingerprint input, the pattern releasing input, and the knock releasing input, the releasing method is applied to the first area 201, Both the release input and the icons associated with the knock release input may be displayed.

In addition, the releasing method is not limited thereto, and may include at least one of the fingerprint input, the pattern release input, and the knock cancel input. The canceling method may include at least one of the fingerprint input, the pattern release input, the knock cancel input, and the face recognition release input depending on whether the user matches the face recognition. At this time, only the icon set as the release method can be displayed in the first area 201.

Meanwhile, FIG. 5 illustrates a method of deactivating the fingerprint recognition sensor when the mobile terminal is placed on a surrounding object according to an embodiment of the present invention. The inactivation method is performed by the control unit 180, and the result is displayed on the display unit 200.

Referring to FIG. 5, the controller 180 determines whether the rear surface is placed in a locked state of the screen. Also, the controller 180 may control the display unit 200 to release the lock screen state based on a release input on the display unit 200 from the user.

For example, according to (b) of FIG. 5, the releasing method includes a fingerprint input, a pattern cancellation input according to whether or not the pattern matches the previously stored pattern, and a knock cancel input . In addition, the canceling method may further include a face recognition release input according to whether the user matches the face recognition.

However, according to (c) of FIG. 5, even if the release method includes both the fingerprint input, the pattern release input, and the knock release input, the fingerprint input is inactivated.

FIG. 6 is a circuit diagram of a touch sensor for detecting whether the mobile terminal according to the present invention is in a contact state (On Held) or a placement state (On Table).

Here, the contact sensor 300 may be a SAR (Specific Absorption Rate) sensor for detecting whether the rear surface of the mobile terminal is in contact with the user's body or in a state of being placed on a surrounding object.

Meanwhile, the SAR sensor is provided in the mobile terminal to reduce the influence of the electromagnetic waves on the user's body. The SAR sensor may be disposed adjacent to an antenna or a communication circuit (integrated circuit) of the wireless communication unit 110. [ This is because the antenna or the communication circuit (integrated circuit) emits electromagnetic waves to the outside.

6 (a) and 6 (b), the touch sensor 200 includes a touch sensor 210, an electrode 220, and a determination unit 230.

6A, when the mobile terminal is in an ON state, the touch sensor 210 detects a first capacitance Cs between a first terminal and a second terminal, and a second capacitance Cs between the first terminal and the ground And has a second capacitance Cp.

On the other hand, according to FIG. 6 (b), when the mobile terminal is in a contact state (On Held), the touch sensor 210 has a first capacitance Cs between a first terminal and a second terminal, A second capacitor Cp between ground and a third capacitance Ct by interaction with the electrode 220 by a user.

6 (a) and 6 (b), the contact sensor 200 can determine whether the rear surface is in contact with or in contact with the user's body, Can be detected.

Meanwhile, when the mobile terminal is in the contact state, the controller 180 controls the wireless communication unit 110 to reduce the transmission power if the transmission power of the wireless communication unit 110 is greater than a predetermined value. Therefore, the SAR sensor can not only determine whether the mobile terminal is in contact with the user's body, but also can reduce the influence of electromagnetic waves on the user's body by controlling the transmission power.

Meanwhile, when the mobile terminal is in the contact state and the method of releasing the locked state of the screen includes fingerprint input, the control unit 180 determines whether the fingerprint input from the back input unit 133 matches the fingerprint of the user Based on whether or not the screen is unlocked.

The controller 180 controls the display unit 200 to release the locked state of the screen based on the cancel input from the user on the display unit 200 when the mobile terminal is in the locked state, ).

7 to 12 illustrate a method of executing an application according to a security level according to the present invention. On the other hand, the method of executing the application according to the security level may be performed by the control unit 180. In addition, a screen to be changed by the application control method performed by the controller 180 may be displayed on the display unit 200.

7 and 8 illustrate a method of selecting an authentication means according to a security level according to an embodiment of the present invention.

With reference to FIG. 7, the priority of the security level may be determined by the priority of the fingerprint input, pin code input, pattern release input, and knock release input.

7 (a) shows a screen for setting the security level. The screen may include a dialog box that allows the user to select the authentication means according to the security level. In addition, the screen may include a GUI for distinguishing between different colors and direction indicators of different levels according to the security level of HIGH, MIDDLE, LOW.

7B shows that fingerprint setting, pin code, knock code, and pattern lock are all selectable when the security level is 'HIGH'.

According to (c) of FIG. 7, fingerprint setting, pin code, knock code, and pattern lock are selected when the security level is 'HIGH'.

According to FIG. 8A, when the security level is 'middle', it indicates that the specific authentication means can not be used according to the security level setting.

According to FIG. 8 (b), when the security level is 'middle', the knock code and the pattern lock are activated so as to be selected, and the fingerprint setting and the pin code are disabled so as not to be selectable. However, the combination of such selections is not limited to the above example, but may include all various combinations.

According to (c) of FIG. 8, when the security level is 'low', it can be activated so that only a pattern lock having the lowest security level can be selected.

7 and 8 may relate to the display method of the application displayed on the display unit 200 based on the method in which the locked state of the screen is released.

Accordingly, when the lock screen state is released, the application displayed or activated on the display unit may be different according to the security level of the method in which the locked state of the screen is released. For example, an application requiring a high security level, such as a bank transfer service, can be displayed or activated when the lock screen status cancellation method is a fingerprint input. On the other hand, if the method of releasing the lock state of the screen is knock code or pattern lock, the application may not be displayed or may be inactivated.

On the other hand, the security level of the application can be basically set by the system, but the security level may be set for each application by the user.

FIG. 9 illustrates a method of setting a security level of an application according to an embodiment of the present invention.

9A, when a user input is received in the application displayed on the display unit 200, the control unit 180 determines that the input is to set or modify the security level of the application. For example, the input may correspond to long pressing an application icon.

According to FIG. 9 (b), the security level may be modified to 'up' and the pin code input may be received from the user to modify the security level.

In addition, the display may also receive consent from the user to move all of the icons to one folder.

Also, according to (c) of FIG. 12, after determining whether the fingerprint input is coincident with the user, the icons can be rearranged according to the security level. In addition, an icon to be added to the folder of the specific security level among the icons of the application whose security level is not set can be received from the user.

Meanwhile, the method of releasing the locked state of the screen of the mobile terminal and the method of executing the application according to the security level based on the method can be performed by the following procedure. 13 is a flowchart illustrating a method of releasing a locked state of a screen of a mobile terminal according to the present invention and a method of executing an application based thereon. The method of releasing the locked state of the screen and the method of executing the application can be performed by the control unit 180 of the mobile terminal having the rear input unit 133. [

The method of releasing the locked state of the screen includes a deactivation state determination process S1310, a contact state detection process S1320, and a fingerprint recognition sensor activation process S1330.

In addition, the method of releasing the lock state of the screen may further include a first lock state releasing step (S1340) or a second lock state releasing step (S1350).

The inactivation state determination process (S1310) determines whether the screen of the display unit mounted on the main body is in an inactive state. The deactivation state includes a case where the user's input from the mobile terminal does not exist for a predetermined time or does not perform communication with an external device.

The contact state sensing process S1320 detects whether the main body is in contact with the user's body by the second sensor corresponding to the contact sensor or the SAR sensor.

In addition, the contact state sensing step S1320 may detect whether the rear surface of the main body is in contact with the user's body or in a state of being placed on the surrounding object. Here, the contact state sensing process (S1320) may determine whether the contact state or the placement state is determined based on the amount of change in the capacitance of the contact sensor. In this regard, the detailed description is replaced with the description in FIG.

The fingerprint recognition sensor activation process S1330 may include activating a fingerprint recognition sensor corresponding to the first sensor to detect a fingerprint of a user contacting the button receiving the input of the user when the second sensor detects contact of the human body do. In addition, the fingerprint recognition sensor activation process (S1330) controls the rear input unit so that the fingerprint recognition sensor is activated when the rear surface is in the contact state in an idle screen state in which the screen is in an inactive state. That is, if the rear surface is in the contact state in the idle screen state, the fingerprint recognition sensor can be activated to control the rear input unit so that the button touch input from the rear input unit is detected as the fingerprint input.

If the fingerprint sensed by the first sensor corresponds to the preset fingerprint, the first lock state canceling process (S1340) releases the locked state. That is, the first lock state canceling process (S1340) cancels the locked state of the screen based on whether the fingerprint input from the rear input unit matches the previously stored fingerprint of the user.

The second lock state canceling process (S1350) controls the display unit to release the locked state of the screen based on the release input on the display unit from the user when the screen is in the inactive state and the rear side is in the deployed state. Here, the cancel input may include at least one of a pattern cancellation input according to coincidence with a previously stored pattern, a knock cancel input according to whether or not the divided area on the display matches the touch, It can be one.

Meanwhile, the method of releasing the locked state of the screen may further include a screen display process (S1360) and a security setting process (S1370).

In the screen display process (S1360), when the screen is unlocked, the application displayed or activated on the display unit controls the screen to be different depending on the security level of the unlocked method. Here, the priority of the security class may be determined according to the priority of the fingerprint input, the pin code input, the pattern release input, and the knock release input.

The security setting process (S1370) controls the display unit to receive additional input from the user for execution of the application when an execution input is detected in the disabled application. Wherein the further input may be at least one of the fingerprint input and the pin code input.

In addition, the method of releasing the locked state of the screen may further include a transmission power control process (S1380). The transmission power control step S1380 controls the radio communication unit to reduce the transmission power if the transmission power of the radio communication unit is greater than a predetermined value when the mobile station is in a contact state.
