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 to the touch screen without touching the object 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.

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.

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.

Here, the tap sensing unit 143 may sense the main body of the mobile terminal 100, the display unit 151, or a gesture of tapping an object. More specifically, the tab may be a tap object such as a finger or the like that lightly touches the body of the mobile terminal 100 or the display unit 151 or an object or tap object to the body of the mobile terminal 100, the display unit 151, It can be understood as an operation of making contact.

The tap object to which the tab is applied may be a body of the mobile terminal 100 or a display unit 151 or an object capable of applying an external force to an object. For example, a finger, a stylus pen, a pen, a pointer, a fist, and the like. The tap object is not limited to an object that can input a touch input to the mobile terminal 100 according to the present invention. The tap object may be a touch screen that can apply an external force to the mobile terminal 100, the display unit 151, If it is an object, its kind is irrelevant.

The object to which the tap gesture is applied may include at least one of the body of the mobile terminal 100, the display unit 151, and the object on which the mobile terminal 100 is placed.

Meanwhile, in the present invention, the tap or tap gesture may be detected by at least one of the acceleration sensor and the touch sensor included in the tap sensing unit 143. [ Here, the acceleration sensor is a sensor capable of measuring dynamic force such as acceleration, vibration, shock, etc. of the main body of the mobile terminal 100.

That is, the acceleration sensor can detect movement (or vibration) of the main body of the mobile terminal 100 generated by the tap gesture and detect whether the tap is applied to the object. Accordingly, the acceleration sensor may detect the taps of the mobile terminal 100 or the display unit 151, or may detect a movement or a vibration of the mobile terminal 100, It is possible to detect that an object positioned close to the object is tapped.

As long as the acceleration sensor can detect movement or vibration of the main body of the mobile terminal 100 as well as when the tab is applied to the mobile terminal 100 or the display unit 151, It is possible to detect the tab even if it is applied to an off-site.

In the mobile terminal according to the present invention, either one of the acceleration sensor and the touch sensor is used, the acceleration sensor and the touch sensor are sequentially used to detect the tabs on the main body of the mobile terminal 100 or the display unit 151 , Or an acceleration sensor and a touch sensor can be used at the same time. On the other hand, in order to sense a tap, a mode using only an acceleration sensor may be named as a first mode, a mode using a touch sensor may be referred to as a second mode, and both the acceleration sensor and the touch sensor may be used Mode) may be referred to as a third mode or a hybrid mode.

On the other hand, when the tab is sensed through the touch sensor, it is possible to more accurately grasp the position where the tab is sensed.

In the mobile terminal 100 according to the present invention, in order to sense the tab through the acceleration sensor or the touch sensor, the power supply unit (not shown) may be connected to the sensing unit 140 even when the mobile terminal 100 is powered off 190 to maintain a minimum current or power applied thereto. This particular mode of operation may be referred to as a 'doze mode'.

For example, in the doze mode, in a touch screen structure in which a touch sensor and a display unit 151 have a mutual layer structure, only a light emitting element for outputting a screen in the display unit 151 is turned off, The sensor may be in the on-state state. Alternatively, the doze mode may be a mode in which the display unit 151 is turned off and the acceleration sensor is kept in an on-state. Alternatively, the dose mode may be a mode in which the display unit 151 is turned off, and both the touch sensor and the acceleration sensor are kept on.

Therefore, when the user is in the doze mode, that is, when the display 151 is turned off, or when the display 151 is turned off (the display 151 is disabled) When the tap is applied to at least one point on the mobile terminal 100 or a specific point of the main body of the mobile terminal 100, it is possible to detect that the tap is applied from the user through at least one of the on- have.

Also, the tap detection unit 143 may determine that a "tab" for controlling the mobile terminal 100 has been detected only when at least two or more tabs are applied within the reference time. For example, when one tap is applied to the display unit 151 by a touch object capable of applying a touch to the display unit 151, the tab sensing unit 143 outputs the one tap as a touch input Can be recognized. That is, in this case, the control unit 180 does not control the function corresponding to the one tap, but the function corresponding to the touch input corresponding to the one tap (for example, A function of selecting an icon) can be controlled.

Accordingly, the control unit 180 may control the operation of one or more functions only when at least two or more tabs (or a plurality of times) that are continuously applied within the reference time are detected by the tap detection unit 143, Quot; tab " is detected.

That is, tap gestures may mean that at least two or more tap gestures are continuously sensed within a reference time. Accordingly, in the following description, the detection of the "tap " may mean that the touch of the user, such as the user's finger or the touch pen, has been detected to the main body or the display unit 151 of the mobile terminal 100 a plurality of times .

In addition, the controller 180 may determine whether the tab is sensed by the user's other finger or one finger, as well as that the tab is sensed within the reference time. For example, when the tabs are sensed by the display unit 151, the controller 180 determines whether the tabs are formed through one finger or through different fingers Can be detected. Alternatively, the control unit 180 recognizes the position where the taps are sensed on the display unit 151 or the acceleration generated due to the taps through at least one of the touch sensor or the acceleration sensor provided in the tap sensing unit 143, You can detect if the tabs are made with one finger or each with a different finger.

Further, the controller 180 may further determine whether the user has input the tabs through one hand or one finger, or whether the user has input through the two hands or at least two fingers It is possible to judge whether or not it is inputted.

The taps may be a plurality of tapes continuously sensed within the reference time. Here, the reference time may be a very short time, for example, 300 ms to 2 s or less.

If the tap detecting unit 143 detects that the main body of the mobile terminal 100 is tapped for the first time, the tap detecting unit 143 detects the first tapping, Can be detected. If the next tap is detected within the reference time, the tap sensing unit 143 or the control unit 180 senses a tab for controlling a specific function of the mobile terminal 100 according to an embodiment of the present invention It can be judged. In this way, the controller 180 recognizes the tab as a valid tap only when the second tab is detected within a predetermined time after the first tab is detected, thereby determining whether the user wants to control the mobile terminal 100, It is possible to distinguish whether a tab is added or not.

There are various methods for allowing the 'valid tap' to be recognized. For example, the control unit 180 may display the main body or the display unit 151 by a second reference number or a second reference number within a predetermined time after a first tap touched by a first reference number or more than a first reference number is detected, It may be recognized that the second tap that is knocked more than the number of times is detected as the 'valid tap'. Here, the number of the first reference times and the number of the second reference times may be equal to or different from each other. For example, the first reference number may be one, and the second reference number may be two. As another example, the first reference number and the second reference number may all be one.

Also, the control unit 180 can determine that the "tabs " are detected only when the tab is within the" predetermined area ". That is, when it is detected that the main body of the mobile terminal 100 or the display unit 151 is tapped for the first time, the control unit 180 may calculate a predetermined area from the point where the first tapping is detected. Then, the control unit 180 determines whether or not the first beat is followed by the first or second reference count or the first or second reference count or more within the reference time from the time when the first beat is detected, It can be determined that the first tab or the second tab is applied.

It is to be understood that the reference time and the predetermined region may be variously modified according to the embodiment.

Meanwhile, the first tap and the second tap may be sensed not only as a reference time and a predetermined area, but also as separate tabs depending on the detected position of each tab. That is, the controller 180 may determine that the first tab and the second tab are applied when the second tab is detected at a position spaced apart by a predetermined distance from the position where the first tab is sensed. When the first tap and the second tap are recognized based on the sensed position, the first tap and the second tap may be simultaneously detected.

Also, when the first tap and the second tap are configured by a plurality of touches, that is, a plurality of tapes, a plurality of touches constituting the first tap and the second tap may be simultaneously detected. For example, when the first touch constituting the first tab is detected and the first touch constituting the second tab is positioned at a position spaced apart from the position where the first touch of the first tab is sensed If it is sensed, the controller 180 can sense the first touch constituting the first tap and the second tap, respectively. The control unit 180 senses additional touch input sensed at each position and determines that the first tap and the second tap are applied when a touch is detected at a first reference frequency or at a second reference frequency at each of the positions can do.

If the tab of the main body of the mobile terminal 100 is detected a plurality of times from the tab detecting unit 143, the controller 180 determines at least one of the functions executable by the mobile terminal 100 One can be controlled.

For example, the control unit 180 may control at least one of the functions executable on the mobile terminal when the plurality of tabs meet the predetermined condition. For example, the control unit 180 may control different functions depending on whether the user uses only one finger or one hand, or at least two fingers or both hands when the user applies the plurality of tabs. Or at least one of the functions executable in the mobile terminal 100 based on the current operation state of the mobile terminal 100 and the environmental state of the mobile terminal 100 may be controlled based on the plurality of taps.

Here, the functions that can be executed on the mobile terminal 100 may mean all kinds of functions that can be executed or operated on the mobile terminal 100. For example, one of the executable functions may be an application installed in the mobile terminal 100. For example, " an arbitrary function is executed " may mean that " an arbitrary application is executed or driven in the mobile terminal 100 ".

As another example, a function executable in the mobile terminal 100 may be a function necessary for the basic operation of the mobile terminal 100. [ For example, the functions necessary for the basic operation may be a function of turning on / off the illumination provided on the display unit 151, switching the mobile terminal 100 from the released state to the locked state, A function of switching to the released state, a function of setting the communication network, a function of changing the setting information of the mobile terminal 100, and the like.

Meanwhile, the power supply unit 190 of the mobile terminal according to the embodiment of the present invention includes a pattern recognition unit (not shown) capable of recognizing a pattern of a user formed from the plurality of taps applied to the mobile terminal 100 in the doze mode state 192). In this case, the pattern recognition unit 192 can compare the pattern formed from the plurality of taps and the pre-stored pattern in the doze mode state, and the control unit 180 and / Power can be applied to each component. The mobile terminal 100 according to the embodiment of the present invention may be configured such that the power of the mobile terminal 100 is turned on based on a plurality of taps applied on the main body or the display unit 151, .

In addition, the function of the mobile terminal 100 executable based on the plurality of taps may be a function of turning off the power of the mobile terminal 100. In this case, the control unit 180 can turn off the power of the mobile terminal 100 by the plurality of taps, and conversely, when the mobile terminal 100 is powered off, . Accordingly, the present invention can control power on / off of the mobile terminal 100 without using the power key.

2 is a view for explaining an example in which power is turned on by a plurality of taps applied in the mobile terminal according to the embodiment of the present invention.

2, the mobile terminal 100 according to the exemplary embodiment of the present invention may be configured such that the light emitting device for outputting a screen in the display unit 151 is off when the power is off, And the tap sensing unit 143, for example, a touch sensor or an acceleration sensor, can be driven in an on mode, that is, a doze mode. 2, the mobile terminal 100 according to the embodiment of the present invention includes a plurality of tabs 201, 202, 203, and 204 applied on the display unit 151, Can be detected.

In this case, the power supply unit 190 can recognize patterns formed from the plurality of taps 201, 202, 203, and 204 through the pattern recognition unit 192. The pattern recognition unit 192 may also determine whether patterns recognized from the plurality of taps 201, 202, 203, and 204 match a preset pattern for turning on the power of the mobile terminal 100 have. When a pattern recognized from the plurality of taps 201, 202, 203 and 204 is matched with a preset pattern, the power supply unit 190 supplies power to each component of the controller 180 and the mobile terminal 100, So that the mobile terminal 100 can be powered on.

The screen 210 displayed on the display unit 151 of FIG. 2 shows such an example. In this case, a screen on which the driving of the mobile terminal 100 starts, that is, a booting screen 210, may be displayed on the display unit 151 as shown in FIG. When the booting of the mobile terminal 100 is completed, a home screen 220 including a predetermined background screen and a plurality of icons may be displayed on the display unit 151. [

Hereinafter, embodiments related to a control method that can be implemented in the mobile terminal 100 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.

3 is a flowchart illustrating an operation of determining whether or not power is applied by a plurality of taps in a mobile terminal according to an exemplary embodiment of the present invention.

3, the power supply unit 190 of the mobile terminal 100 according to an exemplary embodiment of the present invention may apply a minimum amount of power to the sensing unit 140 even when the power of the mobile terminal 100 is off . Accordingly, the tap detecting unit 143 can sense the tapping applied to the main body of the mobile terminal 100 or the display unit 151. A plurality of tapes that can be recognized as valid taps among the plurality of taps can be sensed (S300).

In step S300, when a plurality of tap-detectable beats are sensed, the power supply unit 190 can check the power state of the mobile terminal 100 (S302). When a plurality of taps are applied to the main body or the display unit 151 of the mobile terminal 100 while the mobile terminal 100 is powered on, the power supply unit 190 controls the control of the controller 180 The power for applying the functions corresponding to the plurality of taps may be applied to the necessary components of the mobile terminal 100 in operation S308.

However, if the mobile terminal 100 is turned off in step S300, the power supply unit 190 may include a plurality of taps applied on the main body of the mobile terminal 100 or the display unit 151 The pattern can be detected (S304). For example, the power supply unit 190 senses the positions where the plurality of taps are applied, detects a pattern formed by the plurality of taps based on the positions, or detects not only the positions where the plurality of taps are applied , And may further detect the pattern formed by the plurality of taps by further considering time intervals between the taps applied.

In step S306, the power supply unit 190 may determine whether the pattern detected in step S304 matches the predetermined pattern. The predetermined pattern may be the same pattern as the unlock pattern preset by the user or may be a predetermined code (hereinafter referred to as a POWER-ON pattern) for turning on the power of the mobile terminal 100 ).

The pattern recognition unit 192 may store the power-on pattern. Therefore, the power supply unit 190 can compare the patterns formed from the plurality of taps applied on the main body of the mobile terminal 100 or the display unit 151 with the predetermined power-on patterns, It can be determined whether or not it matches the power-on pattern. The power supply unit 190 may be configured to allow power to be input to the mobile terminal 100 according to a result of the comparison between the pattern and the power-on pattern.

Accordingly, in the mobile terminal 100 according to the embodiment of the present invention, when the power of the mobile terminal 100 is turned off, the plurality of taps applied on the main body or the display unit 151 of the mobile terminal 100 The power of the mobile terminal 100 can be turned on. Therefore, the user can turn on the power of the mobile terminal 100 without using the power key.

The mobile terminal 100 according to the embodiment of the present invention can not only determine the positions of the plurality of tabs applied on the main body or the display unit 151 of the mobile terminal 100, It is mentioned that the interval may be considered. FIG. 4 illustrates an operation of determining whether or not a power source is applied in consideration of positions where a plurality of taps are applied and time intervals between the taps in the mobile terminal according to the embodiment of the present invention.

4, the power supply unit 190 of the mobile terminal 100 according to an exemplary embodiment of the present invention may include a power supply unit 190 for, when a plurality of taps are detected on the main body or the display unit 151 of the mobile terminal 100 , It is possible to detect not only the positions where the taps are sensed but also the time intervals between the taps (S400). Here, the time intervals may be a time interval until another tab (second tab) is applied after any one of the plurality of tabs (first tab) is applied. Alternatively, the time intervals may indicate a time at which the state in which the first tab is applied is maintained until the second tab is applied after the first tab is applied.

On the other hand, if it is detected in step S400 that the positions of the taps and the time interval between the taps are detected, the power supply unit 190 determines that at least one of the positions where the taps are sensed and the time interval between the taps, It can be determined whether or not it matches the pattern (S402). For example, the power supply unit 190 may determine whether the positions where the taps are sensed and the time intervals between the taps are all consistent with predetermined power-on patterns. Alternatively, the power supply 190 may compare the power-on pattern only with the positions where the taps are sensed, or compare only the time intervals between the taps with the power-on pattern.

As a result of the determination in step S402, if at least one of the positions where the taps are sensed and / or the time intervals between the taps does not match the predetermined power-on pattern, the power supply unit 190 may supply the applied plural It may be indicated that the tab of the power-on pattern does not match the preset power-on pattern. For example, the power supply unit 190 temporarily supplies power to the control unit 180 so that a predetermined error message is displayed on the display unit 151 through the control unit 180. [ Alternatively, the power supply unit 190 may temporarily display the error message as a predetermined sound signal, vibration, or LED light signal through the controller 180 to which power is applied. On the other hand, when at least one of the positions where the taps are sensed and / or the time intervals between the taps does not match the preset power-on pattern, the power supply unit 190 may not respond to the plurality of tabs It is possible. In this case, the power supply unit 190 may sense a plurality of tabs for turning on the power of the mobile terminal 100 after a predetermined time elapses.

On the other hand, if it is determined in step S402 that the detected positions match the power-on pattern, the power supply unit 190 applies power to the controller 180 of the mobile terminal 100, The power of each component of the mobile terminal 100 can be applied under the control of the controller 180 (S404). Accordingly, the mobile terminal 100 according to the embodiment of the present invention can be powered on (power on) and booted. Then, as shown in FIG. 2, a predetermined home screen 220 can be displayed.

The controller 180 of the mobile terminal 100 according to an embodiment of the present invention controls the power of the mobile terminal 100 based on the selected mode or the state of the mobile terminal 100, May be determined. For example, when the power of the mobile terminal 100 is turned off in a predetermined manner by the user, the controller 180 controls the operation of the mobile terminal 100 in any one of a power key or patterns formed by a plurality of taps. The power can be turned on. FIG. 5 illustrates an operation of turning off the power in the mobile terminal according to the embodiment of the present invention.

5, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention can detect the power off of the mobile terminal 100 from the user (S500). For example, when the power key is inputted by the user for a predetermined time or more, or when a plurality of tabs applied on the main body or the display unit 151 of the mobile terminal 100 match the preset power- Or when the user selects to turn off the power by connecting to the mobile terminal 100 remotely, it can be determined that the power-off of the mobile terminal 100 is selected by the user.

In this case, the controller 180 may determine whether the power-off mode of the mobile terminal 100 is selected from the user (S502).

If the current power off state of the mobile terminal 100 is not selected by the user as a result of the determination in step S502, the controller 180 determines that the minimum power is applied to the sensing unit 140 The power of the mobile terminal 100 can be turned off. In this case, the mobile terminal 100 according to the embodiment of the present invention may be configured such that even when the power of the mobile terminal 100 is turned off, the main body of the mobile terminal 100 or the display unit 151, The power of the mobile terminal 100 is turned on based on the input of the user detected through the plurality of tabs or the power key because the plurality of tabs applied on the mobile terminal 100 can be detected and compared with the preset power- (S504).

On the other hand, the user can previously select a specific power-off method among the various power-off methods, and determine the power-on method of the corresponding mobile terminal 100 in advance. In this case, if it is determined in step S502 that the current power off state of the mobile terminal 100 is selected by the user, the controller 180 controls the power of the mobile terminal 100 to be turned on The method can be limited.

That is, for example, if the user selects the power off mode by connecting the mobile terminal 100 remotely to the mobile terminal 100, the power off state of the mobile terminal 100 is selected, Off state of the mobile terminal 100. At the same time when the power of the mobile terminal 100 is turned off, the mobile terminal 100 is moved in a predetermined power-on mode corresponding to the currently selected power-off mode, for example, a pattern using a plurality of taps So that the power of the terminal 100 can be turned on. In this case, the control unit 180 can set the power key of the mobile terminal 100 to the locked state simultaneously with the power off, and when the power key is in the locked state, And may be disconnected from the power supply unit 190 so as not to supply the power to each component (S506).

FIG. 6 is for explaining a state in which the mobile terminal according to the embodiment of the present invention is turned off in a predetermined manner in this case.

Referring to FIG. 6, the user can remotely access the mobile terminal 100 and select the power-off of the mobile terminal 100 itself. The remote power off method is a method in which a user who has acquired his or her own mobile terminal 100 uses the mobile terminal 100 or uses the mobile terminal 100 when the user loses his or her mobile terminal 100 May be used to prevent obtaining the stored user ' s personal information. In this case, the user can operate an application for remote connection with his / her mobile terminal 100, from a computer or other mobile terminal or a separate device such as a notebook computer.

In this case, a screen 600 related to the application may be displayed on the separate device. In this case, information (e.g., telephone number 604) related to the connected mobile terminal 100 may be displayed on the screen 600 ). ≪ / RTI > In this state, when the user turns off the power of the user's mobile terminal 100 (602), a control signal for turning off the power of the mobile terminal 100 is transmitted through the base stations 610a and 610b, May be transmitted to the terminal 100.

In this case, the user's mobile terminal 100 may be powered off, as shown in FIG. The control unit 180 of the mobile terminal 100 displays a message 620 indicating that the mobile terminal 100 can be turned on only in a predetermined power on pattern on the display unit 151, Or the like.

Meanwhile, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention determines whether or not the sensing unit 140 is powered on even when the power of the mobile terminal 100 is turned off, And may be determined according to the state of the mobile terminal 100. For example, the control unit 180 may determine whether to maintain the state where the power is applied to the sensing unit 140 even when the power is off, based on the battery state of the mobile terminal 100. This is because, when the power is applied to the sensing unit 140 even when the power is turned off, the power is further consumed.

In this case, the control unit 180 determines whether or not the power supply to the sensing unit 140 is maintained only when the power-off of the mobile terminal 100 is not predetermined by the user, As shown in FIG. This is to prevent the power of the mobile terminal 100 from turning on in a manner other than the predetermined power-on pattern when the user selects the power-off in a specific situation such as the loss of the mobile terminal 100. [

FIG. 7 illustrates the operation of the controller 180 of the mobile terminal 100 according to an embodiment of the present invention.

Referring to FIG. 7, the controller 180 may check the battery status of the mobile terminal 100 when the power off mode is not selected according to the determination in step S502. Then, it is determined whether the battery remaining amount of the mobile terminal is equal to or greater than a preset level (S700).

If it is determined in step S700 that the remaining battery level is equal to or greater than the preset level, the controller 180 turns off the power of the mobile terminal 100, The lowest power may be applied (S702).

For example, the mobile terminal 100 according to an exemplary embodiment of the present invention may include a separate power supply circuit for connecting the power supply unit 190 and the sensing unit 140, (Or the power supply line) may be in a locked state or an open state under the control of the control unit 180. In this case, when the power supply circuit is in the open state, the power supply unit 190 and the sensing unit 140 may be connected to each other to apply the power of the power supply unit 190 to the sensing unit 140 have. On the contrary, when the power supply circuit is in the locked state, the power supply unit 190 is disconnected from the sensing unit 140, and the power of the power supply unit 190 is applied to the sensing unit 140 You can stop things.

In step S702, the controller 180 may set the power supply circuit to an open state before the power of the mobile terminal 100 is turned off. The power of the mobile terminal 100 can be turned off while the power supply circuit is open so that even if the power of the mobile terminal 100 is turned off, To the sensing unit 140. [0050]

However, if it is determined in step S700 that the battery remaining amount is less than the predetermined level, the controller 180 may turn off the power applied to the sensing unit 140 at the same time when the mobile terminal 100 is turned off. Accordingly, when the power is turned off, the control unit 180 can set the power supply circuit to a locked state, so that a predetermined minimum power is applied from the power supply unit 190 to the sensing unit 140 Can be blocked. Accordingly, when the remaining amount of the battery is less than a preset level, it is possible to save the consumed power further.

The mobile terminal 100 according to an embodiment of the present invention may include a plurality of taps on the main body or the display unit 151 of the mobile terminal 100, The power of the mobile terminal 100 may be turned off. For example, if the pattern formed by the plurality of taps on the main body of the mobile terminal 100 or the display unit 151 matches the preset power-off pattern, The power of the mobile terminal 100 may be turned off in response to a plurality of applied taps.

Fig. 8 shows an example of such a case.

8, when a plurality of tabs 800, 802, 804, and 806 are applied to the mobile terminal 100, the controller 180 of the mobile terminal 100 according to an exemplary embodiment of the present invention transmits A pattern formed by a plurality of taps can be recognized. If the recognized pattern matches the preset power-off pattern, the power of the mobile terminal 100 can be turned off in response to the plurality of taps.

On the other hand, as shown in FIG. 8, the controller 180 of the mobile terminal 100 can turn off the power of the mobile terminal 100 when the applied plurality of taps match the predetermined power-off pattern The menu screen 810 can be displayed on the display unit 151. When the user selects power off of the mobile terminal 100, the power of the mobile terminal 100 can be turned off. In this case, the control unit 180 may display a notification window 820 informing that the power is off.

Accordingly, the mobile terminal 100 according to the embodiment of the present invention can control not only power on but also power off of the mobile terminal 100, based on a plurality of taps applied on the main body or the display unit 151 Therefore, it is needless to say that the power key may not be required.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal.
