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 or absence of an object approaching a predetermined detection surface or an object existing in the vicinity without mechanical contact using the force of an electromagnetic field or infrared rays. The proximity sensor 141 may be disposed in an inner region of the mobile terminal covered by the touch screen described above or in the vicinity of 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 type proximity sensor, a magnetic type proximity sensor, and an infrared proximity sensor. When the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of an object having conductivity by a change in an electric field according to the proximity of the object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of description, the act of approaching an object on the touch screen without contacting it so that the object is recognized that it is located on the touch screen is called “proximity touch”, and the touch The act of actually touching an object on the screen is called "contact touch". The position where the object is touched in proximity on the touch screen means a position where the object is perpendicular to the touch screen when the object is touched in proximity. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.) have. Meanwhile, the controller 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.

Furthermore, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) according to whether a touch to the same point on the touch screen is a proximity touch or a contact touch. .

The touch sensor senses a touch (or touch input) applied to the touch screen (or the display unit 151) using at least one of various touch methods such as a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method. do.

As an example, the touch sensor may be configured to convert a change in pressure applied to a specific part of the touch screen or a change in capacitance occurring in a specific part of the touch screen into an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of a touch, an electrostatic capacitance at the time of touch, etc. where a touch object applying a touch on the touch screen is touched on the touch sensor. Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

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

Meanwhile, the controller 180 may perform different controls or may perform the same control according to the type of the touch object that touches the touch screen (or a touch key provided in addition to the touch screen). Whether to perform different controls or the same control according to the type of the touch object may be determined according to the current operating state of the mobile terminal 100 or a running application program.

The ultrasonic sensor may recognize location information of a sensing target by using ultrasonic waves. Meanwhile, the controller 180 may calculate the position of the wave source through information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source may be calculated using the property that light is much faster than ultrasonic waves, that is, the time for light to reach the optical sensor is much faster than the time for ultrasonic waves to reach the ultrasonic sensor. More specifically, the position of the wave source may be calculated using a time difference between the time that the ultrasonic wave arrives using light as the reference signal.

On the other hand, the camera 121 as seen in the configuration of the input unit 120 includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to detect a touch of a sensing target for a 3D stereoscopic image. The photo sensor may be stacked on the display device, and the photo sensor is configured to scan the movement of the sensing target close to the touch screen. More specifically, the photo sensor mounts photo diodes and transistors (TRs) in rows/columns and scans the contents placed on the photo sensor using electrical signals that change according to the amount of light applied to the photo diodes. That is, the photo sensor calculates the coordinates of the sensing target according to the amount of change in light, and through this, location information of the sensing target can be obtained.

The intensity and pattern of vibration generated by the haptic module 153 may be controlled by a user's selection or setting of the controller. For example, the haptic module 153 may synthesize and output different vibrations or output them sequentially.

In addition to vibration, the haptic module 153 is configured to respond to stimuli such as a pin arrangement that moves vertically with respect to the contact skin surface, a jet force or suction force of air through a nozzle or an inlet, a brush against the skin surface, contact of an electrode, an electrostatic force, etc. Various tactile effects can be generated, such as an effect caused by heat absorption and an effect by reproducing a feeling of cold and heat using an element capable of absorbing or generating heat.

Meanwhile, in the present invention, information processed in the mobile terminal may be displayed using a flexible display. Hereinafter, based on the accompanying drawings, this will be described in more detail.

2 is a conceptual diagram for explaining another example of a deformable mobile terminal 200 according to the present invention.

As illustrated, the display unit 251 may be configured to be deformable by an external force. The deformation may be at least one of bending, bending, folding, twisting, and curling of the display unit 251 . Such a deformable display unit 251 may be referred to as a 'flexible display unit'. Here, the flexible display unit 251 may include both a general flexible display, e-paper, and a combination thereof. In general, the mobile terminal 200 may include features of the mobile terminal 100 of FIGS. 1A to 1C or features similar thereto.

A general flexible display refers to a durable display that is not easily broken because it is manufactured on a thin and flexible substrate that can be bent, bent, folded, twisted or curled like paper while maintaining the characteristics of a conventional flat panel display.

In addition, electronic paper is a display technology to which characteristics of general ink are applied, and may differ from conventional flat panel displays in that it uses reflected light. Electronic paper can change information by using a twisted ball or by using electrophoresis using a capsule.

In a state in which the flexible display unit 251 is not deformed (eg, a state having an infinite radius of curvature, hereinafter referred to as a first state), the display area of the flexible display unit 251 becomes a flat surface. In a state deformed by an external force from the first state (eg, a state having a finite radius of curvature, hereinafter referred to as a second state), the display area may be a curved surface. As illustrated, the information displayed in the second state may be visual information output on the curved surface. Such visual information is implemented by independently controlling the light emission of sub-pixels arranged in a matrix form. The unit pixel means a minimum unit for realizing one color.

In the first state, the flexible display unit 251 may be in a curved state (eg, vertically or horizontally curved) instead of in a flat state. In this case, when an external force is applied to the flexible display unit 251 , the flexible display unit 251 may be deformed into a flat state (or less curved) or more curved.

Meanwhile, the flexible display unit 251 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made on the flexible touch screen, the controller 180 (refer to FIG. 1A ) may perform a control corresponding to the touch input. The flexible touch screen may be configured to sense a touch input not only in the first state but also in the second state.

On the other hand, the mobile terminal 200 according to the present modified example may be provided with a deformation detecting means for detecting the deformation of the flexible display unit 251 . Such a deformation detecting means may be included in the sensing unit 140 (refer to FIG. 1A ).

The deformation detecting means may be provided in the flexible display unit 251 or the case 201 to detect information related to deformation of the flexible display unit 251 . Here, the information related to the deformation may be a direction in which the flexible display unit 251 is deformed, a deformed degree, a deformed position, a deformed time, and an acceleration at which the deformed flexible display unit 251 is restored. In addition, it may be various pieces of information detectable due to the bending of the flexible display unit 251 .

In addition, the controller 180 changes information displayed on the flexible display unit 251 or the mobile terminal 200 based on the information related to the deformation of the flexible display unit 251 sensed by the deformation detecting means. It is possible to generate a control signal to control the function of

Meanwhile, the mobile terminal 200 according to the present modification may include a case 201 accommodating the flexible display unit 251 . The case 201 may be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251 .

In addition, a battery (not shown) included in the mobile terminal 200 may also be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251 . In order to implement the battery, a stack and folding method in which battery cells are stacked upward may be applied.

The state transformation of the flexible display unit 251 is not limited only to an external force. For example, when the flexible display unit 251 has a first state, it may be transformed into a second state by a command of a user or an application.

Meanwhile, the mobile terminal 100 according to the present invention may activate a function according to the current driving state of the flexible display unit 251 when a flapping motion of the flexible display unit 251 is detected. Accordingly, the user is provided with the convenience of being able to easily execute a specific function with only a simple operation of flapping the flexible display unit 251 using one hand. Hereinafter, the control of the flexible display according to the present invention will be described in more detail with reference to the accompanying drawings.

3A is a flowchart for a method of controlling function activation based on bending of a flexible display unit according to an embodiment of the present invention, and FIGS. 3B and 3C are conceptual diagrams for explaining the flowchart of FIG. 3A .

As described above, in the mobile terminal according to the present invention, a display unit 251 capable of being bent by an external force and a sensing unit (not shown) for detecting the bending may be mounted on the terminal body.

Referring to FIG. 3A , in the mobile terminal according to the present invention, bending of the display unit having a driving state may be detected by the sensing unit (S310).

The driving state means all kinds of states that the display unit 251 may have in relation to an output when the power of the terminal is turned on. For example, the driving state may include an inactive state in which the lighting of the display unit 251 is turned off, and may include a state in which an execution screen of a specific application is output on the display unit 251 . .

The display unit 251 having the driving state may be bent by an external force, and the bending is sensed by the sensing unit. In this case, the sensing unit may include a separate sensor for detecting the bending of the display unit 251 . For example, the sensing unit may include a bending sensor in order to detect a direction in which the display unit 251 is bent, a length, and the like.

In addition, the warpage may be detected by measuring how much the voltage measured according to the degree of the warpage in the warpage sensor is changed from the reference voltage. For example, the bending sensor may detect that the display unit 251 is bent once when the measured voltage is changed from the reference voltage by more than a preset size. As such, an example of the arrangement of the warpage sensor for detecting the warpage and a method by which the warpage sensor detects the warpage of the display unit 251 will be described later with reference to FIGS. 4A and 4B .

When bending of the display unit 251 is detected by the sensing unit, the control unit 180 determines whether bending of the display unit 251 is detected more than a predetermined number of times for a predetermined time (S320).

When bending of the display unit 251 is detected by the sensing unit, the controller 180 may calculate the number of times the display unit 251 is detected based on a preset time. In this case, the memory unit 170 may store information on the average of the number of times the display unit 251 is bent during the preset time according to the user's flapping motion. Accordingly, the control unit 180 may determine whether the bending of the display unit 251 corresponds to the flapping operation using the average information stored in the memory unit 170 . That is, the control unit 180 may determine that the display unit 251 flaps when bending of the display unit 251 is detected for a predetermined number of times or more during the predetermined time period.

As such, when the flapping of the display unit 251 is detected, the controller 180 activates a preset function corresponding to the driving state of the display unit 251 (S330).

The mobile terminal according to the present invention may activate a preset function corresponding to the driving state of the display unit 251 on condition that the flap of the display unit 251 is detected.

When flapping of the display unit 251 is detected, the controller 180 determines a driving state when the first bending of the display unit 251 is detected. In this case, when the display unit 251 has a plurality of driving states, the controller 180 may prioritize a driving state according to a screen output to the display unit 251 .

For example, when the lighting of the display unit 251 is turned on and an execution screen of a specific function is output to the display unit 251 , the control unit 180 controls the display unit 251 . The driving state may be determined as a state in which the execution screen of the specific function is output. However, the present invention is not limited thereto, and which driving state of the display unit 251 is to be determined with priority may vary depending on the setting.

After the driving state is determined, when a flap of the display unit 251 is sensed, the controller 180 searches for a function corresponding to the determined driving state of the display unit 251 .

The function corresponding to the driving state may be set to a driving state that can be output in the next stage of the driving state in the display unit 251 . For example, when the lighting of the display unit 251 is turned off and in an inactive state, the activation state of turning on the lighting of the display unit 251 may correspond to the driving state of the next step. have. As another example, when the execution screen for the one function is output to the display unit 251 , as the one function is executed, the execution screen of the next step of the execution screen corresponds to the driving state of the next step can do.

However, the driving state of the next stage is not limited to the stage immediately following the current driving state. That is, the function may be set to a driving state corresponding to a stage after several stages of the current driving state. In addition, the function may be set to a specific driving state independent of the current driving state by a user's setting. As such, information on a function corresponding to the current driving state may be stored in the memory unit 170 .

When a function corresponding to the current driving state is found, the controller 180 controls the display unit 251 to activate the searched function. That is, the controller 180 controls the display unit 251 to convert the current driving state to a driving state in which the function is activated. Hereinafter, a specific example will be described with reference to FIGS. 3B and 3C .

Referring to (a) of FIG. 3B , the display unit 251 is illustrated in an inactive state in which lighting is turned off. At this time, as shown in (b) of FIG. 3B , when flapping of the display unit 251 is sensed by the sensing unit, the controller 180 controls the display unit 251 when the first bending due to the flapping is detected. ) to determine the operating state. Then, a function corresponding to the driving state is searched for.

The controller 180 may search for the activation state of the display unit 251 as a function corresponding to the inactive state of the display unit 251 . Accordingly, as shown in (c) of FIG. 3B , the controller 180 controls the display unit 251 to be in an activated state in which the lighting of the display unit 251 is turned on.

As another example, as shown in (a) of FIG. 3C , a lock screen 310 in a locked state in which reception of at least one touch input is restricted may be output on the display unit 251 . At this time, similarly, as shown in (b) of FIG. 3C , when the fluttering of the display unit 251 is sensed by the sensing unit, the controller 180 detects the first deflection according to the fluttering. The driving state of the display unit 251 of Then, a function corresponding to the driving state is searched for.

When a function for canceling the lock state is found as a function corresponding to the driving state of the lock state, the controller 180 performs a function of canceling the lock state of the display unit 251 as shown in FIG. 3C (c). Activate it. Accordingly, the controller 180 may control the display unit 251 to output the home screen page 320 in which the lock state is released while the lock screen 310 is output.

In this way, the user can activate a specific function with a simple gesture using one hand without using both hands. In addition, since the specific function is related to the current driving state of the display unit, the user can easily recognize the function to be executed even if there is no separate indicator for the function that can be activated.

The mobile terminal according to the present invention can execute a specific function by detecting the flap of the display unit 251 . At this time, how the flapping is sensed will be described in detail with reference to FIGS. 4A and 4B .

4A is a view showing an example of arrangement of a bending sensor capable of detecting the bending of the display unit 251, and FIG. 4B is a diagram showing a graph for comparing a general bending operation and a flapping operation according to the present invention to be.

First, referring to FIG. 4A , the mobile terminal according to the present invention may include a plurality of bending sensors for detecting the bending of the display unit 251 . At this time, the bending sensor is preferably arranged to detect the direction and length of the display unit 251 is bent.

Referring to (a) of FIG. 4 , the bending sensors are disposed one at a time on the edge area of the display unit 251 . That is, the bending sensor 401 disposed in the horizontal area of the display unit 251 and the bending sensor 402 disposed in the vertical area of the display unit 251 are each arranged along the edge of the structure. .

As such, when the bending sensor is disposed, when the horizontal region of the display unit 251 is curved, the bending is detected by the horizontal bending sensor 401 . In addition, when the vertical region of the display unit 251 is curved, the bending is detected by the vertical bending sensor 402 . Accordingly, no matter which direction an external force is applied to the display unit 251 , the bending of the display unit 251 may be detected.

In addition, a length corresponding to the curved region of the display unit 251 may be measured due to the bending sensors disposed in the edge region of the display unit 251 . For example, when the horizontal region of the display unit 251 is curved, the horizontal bending sensor 401 may measure a voltage value according to the length to measure the curved length of the display unit 251 .

The warpage sensors may be disposed in the center of the display unit 251 in addition to the edge area. That is, as shown in (b) of Figure 4a, a plurality of the vertical bending sensor 402 in the center of the display unit 251 may be further disposed at a predetermined interval. In addition, as shown in (c) of FIG. 4A , a plurality of the horizontal bending sensors 401 may be further disposed at a preset interval in the center of the display unit 251 .

As described above, since the bending sensors are disposed in the edge area along the horizontal and vertical areas of the display unit 251 , the direction and length in which the display unit 251 is bent can be measured more accurately.

Such bending sensors measure a voltage value according to the bending of the display unit 251, and the control unit 180 can determine the bending of the display unit 251 when the measured voltage value is greater than or equal to a specific voltage value. have. Also, the controller 180 may analyze the curvature characteristic of the display unit 251 by comparing the number and time at which the measured voltage value reaches the specific voltage value.

When the user applies a direct external force to the display unit 251 , it takes time corresponding to the length of the arrow shown in (a) of FIG. 4B until the measured voltage value reaches a specific voltage value from the reference voltage value. That is, when a user applies a direct external force to the display unit 251 , the display unit 251 is gradually bent.

On the other hand, when the user grasps and flutters one area of the display unit 251 , the measured voltage value corresponds to the length of the arrow shown in (b) of FIG. 4B until the measured voltage value reaches a specific voltage value from the reference voltage value. It takes time. That is, by the flapping operation, the display unit 251 reaches the specific voltage value within a relatively short time.

Accordingly, the controller 180 may detect the flutter of the display unit 251 by calculating the number of times the voltage value measured according to the bending reaches the specific voltage value for a preset time. In addition, the user can easily execute a specific function by fluttering using one hand without applying a direct external force to the display unit 251 .

As described above, according to the arrangement structure of the bending sensors, the control unit 180 may determine the length corresponding to the bent region of the display unit 251. In this regard, a method of activating different functions corresponding to the case in which the display unit 251 flaps with different lengths will be described below with reference to FIGS. 5A, 5B and 6 .

FIG. 5A is a diagram illustrating an area in which the display unit 251 is activated is changed by a length corresponding to the area in which the display unit 251 is flapped, and FIG. 5B is a length in which the display unit 251 is flapped. It is a diagram illustrating a change in an activated function when ? is changed, and FIG. 6 is a diagram illustrating an output of an indicator indicating a point to which an external force is applied, when the flutter is varied in length.

Referring to (a) of FIG. 5A , the display unit 251 has a driving state in an inactive state in which lighting is turned off. At this time, as shown in (b) of FIG. 5A , the user may flap while holding a point (eg, a point of the bezel part) of the edge of the display unit 251 . In this case, the warpage sensor disposed in the edge region of the display unit 251 measures the voltage value changed by the flapping operation along the length.

For example, the horizontal bending sensor of the display unit 251 measures a voltage value changed by the flapping operation for each position. Then, the controller 180 analyzes the voltage change value for each location, and identifies points where the voltage value changes. That is, the controller 180 may determine that the region corresponding to the points at which the voltage value changes is curved. Accordingly, the controller 180 may determine the length corresponding to the region in which the change in the voltage value is measured as the curved length of the display unit 251 .

In this case, the controller 180 activates the function corresponding to the inactive state by a length corresponding to the curved area of the display unit 251 . That is, as shown in (c) of FIG. 5A , the control unit 180 may activate a function of outputting the home screen screen 510 to the entire area corresponding to the curved length of the display unit 251 . .

Meanwhile, as shown in (d) of FIG. 5A , the user may hold the center point of the display unit 251 (a point at which line A is located in the drawing) and flap the display unit 251 . At this time, the controller 180 determines the length corresponding to the area where the flapping is sensed. That is, based on the voltage change value for each position measured by the horizontal bending sensor of the display unit 251 , the control unit 180 detects the bent region of the display unit 251 . That is, the controller 180 determines that an area on the display unit 251 except for the area from one point of the bezel part to the point A is curved.

When flapping is detected for the region from the end point of the display unit 251 to the A-line point, the controller 180 controls the display unit 251 to activate a preset function in the region where the flapping is detected. Control. That is, as shown in (e) of FIG. 5A , if the preset function corresponding to the deactivation driving state is to output a home screen screen, the controller 180 places the home screen in one area in which the flapping is sensed. The display unit 251 is controlled so that a part 520 of the screen is output.

In this way, the controller 180 may activate a function only in a region corresponding to the length at which the flapping is sensed. Although the drawing shows the case of being activated in an inactive state, it is not limited thereto. That is, when a flutter is detected while a specific screen is displayed on the display unit 251 , the controller 180 controls the display unit 180 so that only an area corresponding to the sensed length of the flutter is changed to a screen according to activation of another function. The unit 251 may be controlled.

Accordingly, the user is provided with the convenience of activating a function in a desired area of the display unit by adjusting the flapping length of the display unit 251 .

In addition, the user may activate different functions by varying the flapping length of the display unit 251 .

Referring to (a) of FIG. 5B , the display unit 251 has a deactivation driving state. At this time, when the user flaps the display unit 251 as shown in (b) of FIG. 5B , the controller 180 determines that the entire horizontal area of the display unit 251 is flapping. Then, as shown in (c) of FIG. 5B , the control unit 180 outputs the lock screen 510 as a preset function corresponding to the inactive state (switching the display unit to an active state) on the display unit 251 . control

On the other hand, as shown in (d) of FIG. 5B , the user may hold and flap the middle point (point A line) of the display unit 251 . In this case, the control unit 180 controls the display unit 251 by a length corresponding to a predetermined area of the horizontal region of the display unit 251 (the length from the end point of the display unit 251 to the point A line). ) is judged to be fluttering. And, as shown in (e) of FIG. 5B , the controller 180 may control the display unit 251 to output the home screen screen 530 as a function corresponding to the inactive state.

Therefore, even if the user does not have to apply a touch input of several steps to execute a specific function in any driving state of the display unit 251, it can be executed simply by adjusting the length of fluttering the display unit 251. can

In this way, in order to flap the display unit 251 with a different length, the user may flap the display unit 251 by changing a point at which an external force is applied to the display unit 251 . At this time, the controller 180 determines the length at which the display unit 251 must be bent in order to activate a specific function. In addition, an indicator indicating a point at which a user's external force should be applied to the display unit 251 in order to bend the display unit 251 to the determined length may be output.

That is, as shown in (a) of FIG. 6 , the controller 180 displays a specific color at a point 610a on the touch screen of the display unit 251 and a point 610b in the bezel area of the display unit 251 . An indicator that emits light can be output.

Also, as shown in FIG. 6B , the controller 180 may output an icon corresponding to a function activated when holding the one point and flapping it at a point of the display unit 251 . That is, the mobile terminal may be set to activate the message function in response to the display unit 251 being bent by the first length. At this time, the controller 180 places the icon 620a corresponding to the message function at a point where an external force must be applied on the display unit 251 in order to bend the display unit 251 by the first length. can be output.

As another example, the mobile terminal may be configured to activate a call origination function in response to bending of the display unit 251 by a second length. In this case, the controller 180 may output the icon 620b corresponding to the call origination at a point where the display unit 251 is bent by the second length. In addition, the control unit 180 outputs an indicator 620c that emits light in a specific color on the bezel area of the display unit 251 while outputting an icon corresponding to a certain function on the display unit 251, respectively. can do it In this case, when the function that can be activated in the current driving state of the display unit 251 is predictable, the indicator 620c that emits light in the specific color may be output in response to the predictable function.

In this way, the controller 180 may output an indicator indicating a point to which an external force should be applied in order to flap at different lengths to the display unit 251 . Accordingly, the user is provided with information on the function he/she wants to execute in the current driving state of the display unit 251 through the indicator, and is provided with the convenience of smoothly executing the function.

Meanwhile, as the bending of the display unit 251 is detected, the controller 180 compares the number of times the bending is sensed with a preset time to determine the characteristics of the bending. In this case, the controller 180 may determine the speed at which the display unit 251 flaps by detecting a change in the number of times the bending is sensed during the preset time. Hereinafter, with reference to FIGS. 7A, 7B and 8 , the control unit 180 activating different functions in response to the speed at which the display unit 251 flaps will be described.

FIG. 7A is a diagram illustrating that the screen output to the display unit 251 is changed to a screen corresponding to a lower menu as the speed of flapping the display unit 251 is gradually increased.

First, as shown in (a) of FIG. 7A , the display unit 251 outputs the execution screen 700 of the message application focused on the 'receive' menu tab. At this time, as shown in (b) of FIG. 7A , the fluttering of the display unit 251 may be detected by the sensing unit. In addition, as time elapses, as shown in (c) of FIG. 7A , the speed of flapping the display unit 251 may gradually increase.

In this case, the controller 180 may calculate the speed at which the display unit 251 flaps. More specifically, as in the graph 701 shown in (b) of FIG. 7A , the controller 180 controls the display unit 180 by fluttering while half (1/2t) of the preset time t passes. 251) can be counted. Looking at the graph 701, it can be seen that the display unit 251 detects two bendings while half (1/2t) of the preset time t passes.

In addition, as in the graph shown in (c) of FIG. 7A , the control unit 180 calculates the number of times the display unit 251 is bent due to the flapping even while half (1/2t) of the remaining preset time passes. can Similarly, referring to the graph 702 , it can be seen that the display unit 251 detects three bendings while half (1/2t) of the remaining preset time passes.

In this case, the controller 180 may determine that the fluttering speed of the display unit 251 has increased for a preset period of time. In addition, the controller 180 may change the screen currently output on the display unit 251 to a screen including a menu corresponding to a lower level of a menu included in the screen. Accordingly, as shown in (d) of FIG. 7A, the controller 180 displays the execution screen 700 of the message application focused on the 'receive' menu tab, A, which is a submenu of the 'receive' menu tab. It can be changed to a screen 710 about messages with and.

In this way, the user controls the speed of fluttering the display unit 251 without touching the screen output on the display unit 251, including a menu corresponding to a lower level of the menu included in the screen. The convenience of outputting the execution screen is provided.

Meanwhile, the mobile terminal according to an embodiment of the present invention may execute different functions by varying the speed of flapping the display unit 251 .

FIG. 7B is a diagram illustrating a change in an activated function according to the speed at which the display unit 251 is flapped.

Referring to (a) of FIG. 7B , the execution screen 700 of the message application focused on the 'receive' menu tab is output on the display unit 251 . At this time, as shown in (b) of FIG. 7B , when the flap of the display unit 251 is sensed, the controller 180 may calculate the speed of the flap. That is, as in the graph 703 shown in (b) of FIG. 7B , the number of times the display unit 251 has been sensed for bending during a preset time t may be calculated. Accordingly, as shown in the graph 703 , the controller 180 may determine that the display unit 251 is bent twice during the preset time t according to the flapping.

When the speed according to the flutter is calculated, as shown in (c) of FIG. 7B, the controller 180 controls a screen corresponding to a preset function (a screen corresponding to a sub-menu of the 'Receive' menu tab, message content with A in the drawing) The display unit 251 is controlled so that an execution screen 710 is output. In this case, the preset function may be determined according to the calculated speed.

Meanwhile, as illustrated in (d) of FIG. 7B , the flapping of the display unit 251 may be sensed. In this case, referring to the graph 704 shown in (d) of FIG. 7B , it can be seen that the display unit 251 is bent 3 times by the flapping operation for a preset time t. Accordingly, the controller 180 may control the display unit 251 to activate a function corresponding to the speed calculated by the flapping operation. That is, as in (e) of FIG. 7B , the control unit 180 controls the function corresponding to the fluttering speed of the display unit 251 according to the graph 704 (the 'Send' menu in the 'Receive' menu tab of the message application) function to navigate to tabs). Accordingly, the execution screen 720 on which the 'Send' menu tab is focused may be output on the display unit 251 .

In this way, by flapping the display unit 251 at different speeds, the controller 180 can activate different functions corresponding to the calculated speeds. In this case, the memory unit 170 may store a function that can be activated in response to the flapping speed of the display unit 251 . Accordingly, the user can easily execute different functions by changing the speed of flapping the display unit 251 in the current driving state of the display unit 251 .

The control unit 180 may output an indicator capable of providing information on a function activated according to the speed of flapping the display unit 251 on the display unit 251 .

FIG. 8 is a diagram illustrating that the display unit 251 outputs an indicator of a function that can be activated in response to a flapping speed.

First, referring to FIG. 8A , an execution screen 800 of a message application focused on a 'receive' menu tab is output on the display unit 251 . At this time, when the flap of the display unit 251 is sensed, an indicator 810 indicating the speed of the flap may be output in the form of a bar as shown in FIG. 8B . That is, when the fluttering of the display unit 251 is detected, the controller 180 calculates the fluttering speed and displays an indicator 810 corresponding to the calculated speed in the form of a bar on the display unit 251 . can be printed on

Also, the controller 180 may output the indicator 810 to include information on a function that can be executed as the speed of the fluttering gradually increases. That is, as shown in FIG. 8B , the controller 180 may display information on the message view 810a corresponding to the function for checking the message content on the indicator 810 . Also, the controller 180 may display information on the outgoing menu 810b corresponding to a function capable of moving the focus from the 'receive' menu tab to the 'send' menu tab.

Also, as the speed of the fluttering gradually increases, the controller 180 may move the bar having a specific color of the indicator 810 to correspond to the speed. That is, when the speed of flapping the display unit 251 gradually increases, the controller 180 may calculate the degree to which the speed gradually increases. In addition, the controller 180 may move a bar of a specific color output to the indicator 810 to correspond to the degree to which the speed gradually increases. Accordingly, as shown in FIG. 8C , as the flapping speed of the display unit 251 increases, the bar of a specific color output to the indicator 810 may move.

At this time, when the bar of a specific color output to the indicator 810 moves to a point where information corresponding to a certain function is located on the indicator 810 , the controller 180 controls the information corresponding to the point. Activate the function. That is, as shown in (c) of FIG. 8, when the bar of the specific color moves and moves to a point where the message view 810a information is located, as shown in (d) of FIG. 8, the controller 180 The display unit 251 may be controlled so that an execution screen 820 related to the message content is output.

In this way, the controller 180 provides the user with an indicator corresponding to the flapping speed, so that the user can check the speed at which he or she flaps the display unit 251 and a function that can be activated corresponding to the speed. have.

Meanwhile, the controller 180 may analyze the bending pattern of the display unit 251 by determining the number of times the display unit 251 flaps at a specific time interval. In this regard, it will be described below with reference to FIGS. 9, 10A, 10B, and 10C.

9 is a diagram illustrating activation of a specific function according to the number of times that the display unit 251 flaps at a specific time interval.

Referring to FIG. 9A , a lock screen 900 is output on the display unit 251 . At this time, as shown in (b) of FIG. 9 , after the user flaps the display unit 251 , as shown in FIG. 9( c ), the user may maintain the display unit 251 in a stationary state. Also, after maintaining the stationary state for a specific time, the display unit 251 may be fluttered again as shown in FIG. 9(d).

At this time, the controller 180 detects that the display unit 251 is in a rest state in which the display unit 251 is maintained in a stationary state for a specific time after the one-time flutter is sensed, and the display unit 251 flutters again. When detected, it can be determined as one bending pattern. That is, the controller 180 may determine the number of times the display unit 251 flaps at an interval between the idle state in which the display unit 251 is sensed as a stationary state for a specific time as one bending pattern.

In addition, the controller 180 may activate a preset function to correspond to the curvature pattern. In this case, information on a preset function corresponding to the number of times the display unit 251 flaps with the idle state as an interval may be stored in the memory unit 170 . Accordingly, the controller 180 controls the display unit 251 to activate a preset function corresponding to the specific number of times when it is sensed that the display unit 251 flaps a certain number of times with the idle state as an interval. can do.

Accordingly, as shown in FIG. 9E , when a specific curvature pattern is detected in the lock screen 900 state, the controller 180 outputs the execution screen 910 of the camera application according to the activation of the camera function. (251) can be controlled. Although the drawing shows a bending pattern related to detecting the second flap of the display unit 251 at intervals of the idle state, the bending pattern is not limited thereto. For example, as the flapping of the display unit 251 is sensed three or more times at intervals of the idle state, the bending pattern may be set in various ways without limiting the number of times.

The mobile terminal according to the present invention may set a password for restricting execution of a specific function on the display unit 251 by using the bending pattern.

FIG. 10A is a diagram illustrating the cancellation of the password of the password setting screen by using the bending pattern.

Referring to (a) of FIG. 10A , a lock screen 1000 with a password set is output on the display unit 251 . At this time, as shown in (b) of FIG. 10A, the display unit 251 may be flapped, and the display unit 251 may be maintained in a stationary state for a specific time as shown in (c) of FIG. 10A. In addition, the display unit 251 maintained in the stationary state may be fluttered again as shown in (d) of FIG. 10A.

In this case, the controller 180 detects that the flapping of the display unit 251 is detected twice at intervals of the idle state. In addition, the controller 180 may control the display unit 251 to cancel the lock screen 1000 to which the password is set and to output the home screen screen 1010 in response to the bending pattern.

At this time, the bending pattern for decrypting the password may include information on the length of bending as the display unit 251 flaps in addition to sensing the flapping of the display unit 251 a certain number of times with an interval between the idle state. .

10B and 10C are diagrams illustrating a case in which information on a length in which the display unit 251 is bent according to flapping is included in a bending pattern for decryption.

As shown in (a) of FIG. 10B , in a state in which the lock screen 1000 with a password set is output on the display unit 251 , the user displays the end point (bezel part) of the display unit 251 as shown in FIG. 10B (b). Any point located in the ) can be held and flapped. In this case, the controller 180 may determine that the length corresponding to the entire horizontal region of the display unit 251 is bent.

Thereafter, as in (c) of FIG. 10b, the user maintains the display unit 251 in a stationary state for a specific time, and then moves the center (point A line) of the display unit 251 as shown in (d) of FIG. 10b. Can hold and flap. In this case, the controller 180 may determine that the display unit 251 is bent from the end point of the display unit 251 by a length corresponding to the point where the A line is located. When the warpage pattern is detected, the controller 180 may control the display unit 251 to cancel the password setting lock screen 1000 and output the home screen screen 1010 .

As such, when the display unit 251 is flapped at intervals of the rest state, the bending pattern may be formed by varying the bending length of the display unit 251 .

FIG. 10C is a diagram illustrating a case in which the bending pattern flutters so that a length corresponding to the point of the A line (a line located at the center of the display unit) from the end point of the display unit 251 is curved. At this time, determining the bending pattern and canceling the encryption setting is replaced with the description of FIG. 10B .

As described above, the mobile terminal according to the present invention may set the password according to the bending pattern formed by the fluttering of the display unit 251 . In addition, in the bending pattern, in addition to the number of times the display unit 251 flutters at intervals of a rest state sensed as a stationary state for a specific time, the length, speed, etc. at which the display unit 251 is bent may be variously formed. can Accordingly, the user can receive privacy protection by setting and canceling the password with a simple gesture using one hand without a separate touch.

A mobile terminal and a control method thereof according to an embodiment of the present invention may execute a specific function using a display unit that can be bent by an external force. In this case, the user is provided with the convenience of executing the specific function with only a simple operation of flapping the display unit using one hand. In addition, since the specific function corresponds to the current driving state of the display unit, the user can easily execute a desired function by making an appropriate gesture according to the current driving state.

In addition, in addition to executing a specific function, it is possible to set a password restricting the function execution by variously applying the fluttering operation, and there is an effect that the user's privacy can be protected.

The present invention described above can be implemented as computer-readable code on a medium in which a program is recorded. The computer-readable medium includes all types of recording devices in which data readable by a computer system is stored. Examples of computer-readable media include Hard Disk Drive (HDD), Solid State Disk (SSD), Silicon Disk Drive (SDD), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc. There is also a carrier wave (eg, transmission over the Internet) that is implemented in the form of. In addition, the computer may include the control unit 180 of the terminal. Accordingly, the above detailed description should not be construed as restrictive in all respects but as exemplary.
