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 present in the vicinity without using a mechanical contact by using an electromagnetic force 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 near the touch screen.

Examples of the proximity sensor 141 include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object by the change of the electric field according to the proximity of the conductive 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 explanation, an action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching an object on a screen is called a "contact touch." The position at which the object is in close proximity touch on the touch screen means a position where the object is perpendicular to the touch screen when the object is in close proximity touch. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, and a proximity touch movement state). have. Meanwhile, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern detected 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. Further, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) according to whether the touch on the same point on the touch screen is a proximity touch or a touch touch. .

The touch sensor applies 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. Detect.

As an example, the touch sensor may be configured to convert a change in pressure applied to a specific portion of the touch screen or capacitance generated at the specific portion into an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the touch, a capacitance at the touch, and the like, when the touch object applying the touch on the touch screen is touched on the touch sensor. Here, the touch object is an object applying 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, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and then transmits the corresponding data to the controller 180. As a result, the controller 180 can know which area of the display unit 151 is touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

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

Meanwhile, the touch sensor and the proximity sensor described above may be independently or combined, and may be a short (or tap) touch, a long touch, a multi touch, a drag touch on a touch screen. ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, etc. A touch can be sensed.

The ultrasonic sensor may recognize location information of a sensing object using ultrasonic waves. On the other hand, the controller 180 can calculate the position of the wave generation source through the information detected from the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time when the ultrasonic wave reaches the ultrasonic sensor.

Meanwhile, various embodiments of the present disclosure may be implemented in a recording medium readable by a computer or a similar device using, for example, software, hardware, or a combination thereof.

Meanwhile, in the present invention, the information processed by the mobile terminal can be displayed using a flexible display. Hereinafter, this will be described in more detail with reference to the accompanying drawings.

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

As shown, 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. The deformable display unit 251 may be referred to as a "flexible display unit". Herein, the flexible display unit 251 may include both a general flexible display, an electronic paper, and a combination thereof. In general, the mobile terminal 200 may include the features of the mobile terminal 100 of FIGS. 1A-1C or similar features.

A general flexible display is a light and durable display that is fabricated on a thin and flexible substrate that can be bent, bent, folded, twisted or curled like a paper while maintaining the characteristics of a conventional flat panel display.

In addition, electronic paper is a display technology to which the characteristics of general ink are applied, and the use of reflected light may be different from that of a conventional flat panel display. Electronic paper can change information using twist balls or electrophoresis using capsules.

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

The flexible display unit 251 may be placed in a bent state (eg, bent vertically or horizontally) instead of being flat in the first 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 state) or more curved state.

Meanwhile, the flexible display unit 251 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made with respect to the flexible touch screen, the controller 180 (refer to FIG. 1A) may perform control corresponding to the touch input. The flexible touch screen may be configured to detect 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 modification may be provided with deformation detection means for detecting the deformation of the flexible display unit 251. Such deformation detection means may be included in the sensing unit 140 (see FIG. 1A).

The deformation detecting means may be provided in the flexible display unit 251 or the case 201 to sense information related to deformation of the flexible display unit 251. Herein, the information related to the deformation may include a direction in which the flexible display unit 251 is deformed, a degree of deformation, a deformation position, a deformation time, and an acceleration in which the flexible display 251 is restored. In addition, due to the bending of the flexible display unit 251 may be a variety of information that can be detected.

In addition, the controller 180 changes the information displayed on the flexible display unit 251 or changes the information displayed on the flexible display unit 251 based on the information related to the deformation of the flexible display unit 251 detected by the deformation detecting means. It can generate a control signal for controlling the function of.

Meanwhile, the mobile terminal 200 according to the present modified example may include a case 201 for 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 characteristics of the flexible display unit 251.

In addition, the 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 characteristics of the flexible display unit 251. In order to implement the battery, a stack and folding method in which battery cells are stacked up may be applied.

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

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

3 is a flowchart illustrating a method of controlling a mobile terminal according to a bending characteristic of a flexible display unit in a mobile terminal according to an exemplary embodiment of the present invention. 4A, 4B, 4C, and 4D are conceptual views illustrating a posture of the flexible display unit. 5 is a conceptual diagram illustrating an example in which a plurality of screen information having an output order is stored in a memory unit. 6A, 6B, 6C, 6D, and 6E are conceptual views illustrating a method of controlling screen information by using a bending characteristic of the flexible display unit.

The present invention may include the flexible display unit 251 described with reference to FIG. 2. In this case, the mobile terminal according to an embodiment of the present invention may proceed to display one of the screen information of the plurality of screen information, the output order is set in the flexible display unit (S310).

The present invention may be a mobile terminal having a flexible display unit 251. The flexible display unit 251 may be bent, curled, or folded. For example, as illustrated in (a) of FIG. 4A, an external force may be applied while the flexible display unit 251 is unfolded. Here, the external force may mean a force for changing the shape of the flexible display unit 251, for example, a force applied from the user.

When the external force is applied, as shown in (b) of FIG. 4A, the flexible display unit 251 may be bent. In this case, the mobile terminal according to an exemplary embodiment of the present disclosure may detect the degree of bending as the flexible display unit 251 is bent. More specifically, the degree of deflection may be the average degree of deflection of the degree of curvature of the outer surface and the degree of curvature of the flexible display unit 251.

In this case, the controller 180 may change the display state of the screen information displayed on the flexible display unit 251 according to the degree of bending of the flexible display unit 251. The display state may mean a display state that is visually changed by bending, such as a display size, a display position, and a display form.

More specifically, the controller 180 may determine the display position and the display size at which the screen information is to be displayed by the bending when the bending of the flexible display unit 251 is detected. For example, the controller 180 may control the position and size of the screen information so that the screen information displayed on the entire display area of the flexible display unit 251 is displayed only in a partial display area.

In addition, the mobile terminal may further include a memory unit 170 for storing a plurality of screen information, the output order is set in advance.

Here, the plurality of screen information may include visual information that can be displayed on the flexible display unit 251 of the mobile terminal, such as an image, a music file, and a video. In addition, the plurality of screen information may be information capable of outputting not only visual information but also audio information.

In addition, the output order may be an order displayed on the flexible display unit 251 in response to an output command applied to the mobile terminal. That is, the controller 180 may output screen information based on the output order when a user's output command is applied.

More specifically, referring to FIG. 5, a plurality of screen information may be stored in an output order. For example, referring to FIG. 5, in the memory unit 170, three screen information A 500, B 510 C C 520, and an output order of the three screen information are stored. When the output command is applied to the mobile terminal, the controller 180 may output the screen information A and 500 having the fastest output order among the three screen information according to the output order. Thereafter, when the control command for outputting the next screen information is received in the state in which the screen information (A, 500) having the fastest output order is output, the controller 180 performs different screen information (B) according to the output order. , 510 may be output.

In this case, when the control command for outputting the next screen information is received, the controller 180 may output the screen information (C, 520), which is the next output order, based on the currently output screen information (B, 510). .

On the contrary, when a control command for outputting previous screen information is received, the controller 180 can output screen information (B, 510), which is a previous output order, based on the currently output screen information (C, 520). have.

As such, when the output order is stored in the memory unit 170, the controller 180 may output the screen information in order based on the output order.

In this case, any one screen information to be displayed on the flexible display unit 251 among the plurality of screen information may be selected by the user. For example, in a state where at least some of a plurality of images stored in the memory unit 170 are displayed on the flexible display unit 251, the user selects any one of the at least some portions, thereby selecting any one of the flexible display units ( 251). Here, the user's selection may be made by applying a touch on any one image.

In the state where any one screen information is displayed on the flexible display unit, the mobile terminal according to an embodiment of the present invention may detect the posture of the flexible display unit based on the direction of gravity (S320).

The controller 180 may detect the posture of the flexible display unit 251 based on a virtual reference line having a direction coinciding with the gravity direction. At this time, the mobile terminal according to an embodiment of the present invention may further include a gravity sensor.

Here, the posture of the flexible display unit 251 may be any one of a first posture measured based on the reference line and a second posture rotated 180 degrees from the first posture.

For example, as shown in (a) of FIG. 4B, the first posture is a posture in which the flexible display unit 251 is erected in a direction coinciding with the gravity direction with respect to the reference line a-a '. Can mean.

In addition, as shown in (b) of FIG. 4B, the second posture may mean a posture in which the flexible display unit 251 is erected in a direction opposite to the gravity direction based on the reference line a-a '. . In other words, the second posture is a posture rotated by 180 degrees from the first posture with respect to the reference line.

In addition, the mobile terminal may have a posture at various angles based on the reference line as well as the first and second postures. In this case, the controller 180 may detect the posture of the mobile terminal by detecting an angle formed clockwise based on the reference line.

Hereinafter, a case in which one of the first posture and the second posture is in a posture will be described. However, the present invention is not limited thereto and may be applied to postures at various angles based on the reference line.

When the posture is sensed, the mobile terminal according to an embodiment of the present disclosure may display a screen to be displayed on the flexible display unit based on the position of the bent end outwardly of both ends of the flexible display unit based on the detected posture. Determining the information may proceed (S330).

The flexible display unit 251 may be bent, folded, or curled. In this case, the controller 180 may control various functions of the mobile terminal by using a drying characteristic of the flexible display unit 251.

More specifically, the controller 180 may sense that both ends of the flexible display unit 251 overlap due to the bending of the flexible display unit 251. In this case, sensors at both ends of the flexible display unit 251 may detect overlap. For example, both ends of the flexible display unit 251 may be provided with a magnetic flux sensor for detecting a change in magnetic flux, a bending sensor for determining the degree of bending. The bending sensor may include a pressure sensor, a strain gauge, and the like.

In addition, when both ends of the flexible display unit 251 overlap due to the bending of the flexible display unit 251, the controller 180 may determine a position of an outer side of the both ends of the flexible display unit 251. Can be. Here, the step that is bent outwardly, when both ends are overlapped, may mean a step that is overlapped upward of both ends. For example, when one end of both ends overlaps the other end, the outwardly curved end may be any one of the above.

In this case, the position of the outwardly curved end may vary according to the posture of the mobile terminal. For example, when the mobile terminal is in the first posture and in the second posture, the positions of the outwardly bent ends may be different positions.

More specifically, as shown in Figure 4c, the mobile terminal may have a first posture. In this case, as shown in (a) of FIG. 4C, the controller 180 may detect that a stage located at the left side of both ends of the flexible display unit 251 overlaps the stage disposed at the right side. On the contrary, as shown in (b) of FIG. 4C, the controller 180 may sense that the right end of both ends of the flexible display unit 251 is overlapped with the left end. .

On the other hand, as shown in Figure 4d, the mobile terminal may have a second posture. In this case, as shown in (a) of FIG. 4D, the controller 180 may determine that the end bent outward is the end positioned on the left side. At this time, the mobile terminal shown in (a) of FIG. 4d has the same curved shape as (b) of FIG. 4c, but only the attitude of the mobile terminal is changed. That is, the controller 180 may determine the bent ends of the outer groups in different positions according to the posture of the mobile terminal even if the controller 180 is bent in the same shape.

In addition, as shown in (b) of FIG. 4D, in the state where the mobile terminal is in the second posture, the controller 180 has the right end of the both ends of the flexible display unit 251 on the right side. It can be detected that the location.

In this case, the controller 180 may control the function of the mobile terminal based on the position of the step bent outward. Here, the functions of the mobile terminal may include a function of executing and controlling an application installed on the mobile terminal, a function of switching a locked state to a released state, a function of terminating a currently running application, and a function of entering a home screen page. It can contain all the functions that can be operated on.

On the other hand, the present invention will be described a method of controlling the display information when the display order is set on the flexible display unit 251, the output order, but in the case of the ordered function, the bending characteristics of the flexible display unit 251 The same would be applicable.

Hereinafter, a method of determining the screen information to be displayed on the flexible display unit 251 according to the position of the end bent outward of the both ends of the flexible display unit 251 6a, 6b, 6c, FIG. 6D and 6E will be described in more detail.

When a bending is detected on the flexible display unit 251, the controller 180 may determine screen information displayed on the flexible display unit 251 according to the bending characteristic. In this case, the controller 180 may determine the screen information to be displayed on the flexible display unit 251 by relating the bending characteristic to the output order stored in the memory unit 170.

For example, when it is detected that the flexible display unit 251 is bent in a preset form, the controller 180 may execute a function associated with the preset form based on the output order. More specifically, the controller 180 may execute a function of outputting screen information having a faster output order than screen information currently being output based on the output order. Here, the function associated with the preset form may be set at the time of factory shipment of the mobile terminal or may be set by the user's selection.

Here, the bending characteristic of the flexible display unit 251 may refer to a feature in which both ends of the flexible display unit 251 are overlapped due to the bending of the flexible display unit 251. More specifically, the bending characteristic may be a position of an end bent outward while both ends of the flexible display unit 251 overlap each other.

In this case, the controller 180 may detect the bending characteristic based on the posture of the mobile terminal. Here, the attitude of the mobile terminal may be set based on a reference line having the gravity direction as the reference direction.

Meanwhile, when the screen information to be output is determined by the bending of the flexible display unit 251 in the state where the screen information is being output, the controller 180 newly determines the screen information being output. Can be changed to screen information.

In addition, the controller 180 may display the screen information being output and the screen information to be newly output together. For example, the controller 180 may change the size and position of the existing screen information and output the screen information together with the newly output screen information.

Hereinafter, a description will be given of a case in which screen information being outputted previously disappears due to a bending characteristic of the flexible display unit 251, and only screen information to be newly output is displayed on the flexible display unit 251. Both screen information and newly output screen information may be applicable.

For example, as illustrated in (a) of FIG. 6A, any one screen information 510 of a plurality of screen information stored in the memory unit 170 may be displayed on the flexible display unit 251. Here, one piece of screen information may be screen information on which an output request is received by a user.

In the state in which the screen information 510 is displayed, the controller 180 can detect the bending of the flexible display unit 251. In this case, the controller 180 may further detect the posture of the mobile terminal together with detecting the bending. For example, as shown in (a) of FIG. 6A, the posture of the mobile terminal may be a first posture having a direction coinciding with the gravity direction.

When the mobile terminal is in the first posture, the controller 180 may sense the position of the end that is bent to the outside of both ends of the flexible display unit 251 based on the first posture. In this case, the controller 180 may determine the screen information to be displayed on the flexible display unit 251 based on the position of the step bent outward.

More specifically, the controller 180 controls the flexible display unit 251 to output screen information having a faster output order than the currently output screen information 510 when the position of the bent end is the first position. Can be controlled. On the contrary, the controller 180 controls the flexible display unit 251 to output screen information whose output order is later than that of the currently output screen information 510 when the position of the bent outward stage is the second position. can do.

For example, as shown in (b) of FIG. 6A, when the position of the outwardly bent stage is located at the left side, the controller 180 outputs a screen having a faster output order than any one of the screen information 510. Information 500 may be detected from the memory unit 170. In addition, the controller 180 may output the screen information 500 having the quick output order to the flexible display unit 251.

As another example, as shown in (c) of FIG. 6A, the controller 180 outputs a screen whose output order is later than that of any one screen information 510 when the position of the outwardly bent stage is located on the right side. Information 520 may be detected from the memory unit 170. In addition, the controller 180 may output the screen information 520 having the late output order to the flexible display unit 251.

Meanwhile, the mobile terminal may be in a second posture rotated 180 degrees from the first posture. In this case, the controller 180 may determine the position of the step bent toward the outside based on the second posture.

For example, as shown in (a) of FIG. 6B, the mobile terminal may be in a second position having a direction opposite to the direction of gravity. Referring to FIG. 6B (a), in the state where the mobile terminal is in the second posture, the screen information 510 of any one of the plurality of screen information stored in the memory unit 170 is stored on the flexible display unit 251. Can be displayed. Here, even when the mobile terminal is in the second posture, the screen information to be displayed on the flexible display unit 251 may have a display direction that matches the gravity direction. Through this, the user may be provided with a screen always having a direction that matches the gravity direction, regardless of the posture of the mobile terminal.

In addition, in the second posture of the mobile terminal, the controller 180 can detect the bending of the flexible display unit 251. In this case, the controller 180 may detect a position of a bent outward of both ends of the flexible display unit 251 based on the second posture. In addition, the controller 180 may determine screen information to be displayed on the flexible display unit 251 according to the position of the outer stage.

For example, as illustrated in (b) of FIG. 6B, when the position of the outwardly bent stage is at the first position, the one screen may be one of the screens based on the second posture. The flexible display unit 251 may be controlled to output the screen information 500 having a faster output order than the information 510.

In addition, as shown in (c) of FIG. 6B, when the position of the outwardly bent stage is at the second position with respect to the second posture, the control unit 180 may include any one screen information ( The flexible display unit 251 may be controlled to output the screen information 500 which is later in output order than that of 510.

6A and 6B, according to the attitude of the mobile terminal, even if the folded state of the flexible display unit 251 is the same, the position of the bent outward side may vary. According to the present invention, various controls can be performed by using a position of an end curved outwardly according to the posture of the mobile terminal.

More specifically, as shown in (a) of FIG. 6C, in the first posture of the mobile terminal, an end curved toward the outside of the flexible display unit 251 may be located on the left side.

In this case, the posture of the mobile terminal may be changed while the curved state of the flexible display unit 251 is fixed. In this case, the controller 180 may sense that the position of the bent end of the flexible display unit 251 is changed. For example, as illustrated in (a) and (b) of FIG. 6C, the controller 180 is in a posture of the mobile terminal in a state in which the position of the bent end of the flexible display unit 251 is left. When it is detected that the change from the first posture to the second posture, it can be detected that the position of the bent end is also changed to the right.

In this case, the controller 180 may change any one of the screen information 510 displayed on the flexible display unit 251 into another screen information 500 by changing the position of the curved end. For example, as illustrated in (b) of FIG. 6C, the controller 180 controls the screen information 500 to be displayed on the flexible display unit 251 in which the output order is faster than any one of the screen information. can do.

That is, according to the present invention, not only the bending characteristic of the flexible display unit 251, but also the position of the end curved outward may be determined based on the change of the attitude of the mobile terminal.

Meanwhile, in the above description, when the flexible display unit 251 is folded in an unfolded state, the screen information is controlled. However, in the present invention, even when the flexible display unit 251 is folded in another form, the present invention may be folded. Similarly applicable.

More specifically, the controller 180 may change the folded state of the flexible display unit 251 in a state where the posture of the mobile terminal is not changed, thereby changing the position of the stage bent outward. For example, the controller 180 may change a stage that is bent outward of the flexible display unit 251 from left to right.

In this case, the controller 180 may change the screen information displayed on the flexible display unit 251 to other screen information based on the changed position of the outwardly curved end. For example, the controller 180 may control the flexible display unit 251 to output the screen information whose output order is later than that of the currently output screen information when the outward curved stage is changed to the right side.

In addition, the controller 180 may control the screen information displayed on the flexible display unit 251 by repeating the bent state and the unbent state of the flexible display unit 251.

For example, as illustrated in (a) and (b) of FIG. 6D, the controller 180 may display the screen information currently output according to the position of the end bent outward by the bending of the flexible display unit 251. 520 may be changed to the screen information 510 having a quick output order.

In this case, as illustrated in (c) of FIG. 6D, the controller 180 may detect that the flexible display unit 251 is changed to a flat state in a curved state. In this case, the controller 180 may control the flexible display unit 251 to output the screen information 510 displayed on the flexible display unit 251 in a flat state.

In this case, the controller 180 may detect that the positions of the ends bent to the outside of the flexible display unit 251 are equally bent. In this case, the controller 180 may output the screen information 500 having the quick output order based on the screen information 510 output in the flat state on the flexible display unit 251.

On the contrary, FIG. 6E illustrates a case in which the positions of the bent ends of the flexible display unit 251 are opposite. As described above, when the flexible display unit is bent in the flexible display unit, when the flexible display unit is unfolded, the screen information 510 whose output order is later than the currently displayed screen information 500 may be displayed. .

In this case, when the bending is detected again in the unfolded state, the flexible display unit (200) is output such that the screen information 520 having a later output order is output based on the screen information 510 having a later output order. 510 may be controlled.

In the above, it has been described that the screen information is changed in accordance with the position of the end bent outward of both ends of the flexible display unit. Through this, the user may control the mobile terminal more intuitively only by the bending position of the flexible display unit.

Hereinafter, a method of changing an image displayed on the flexible display unit will be described in more detail. 7A and 7B are conceptual views illustrating a method of changing screen information displayed on the flexible display unit.

The controller 180 may change the currently output screen information into another screen information by using the bending characteristic of the flexible display unit. For example, as illustrated in (a) of FIG. 7A, the controller 180 is configured to display the flexible display unit 251 in a state in which one image 510 is output on the flexible display unit 251. Detect deflection

In this case, the controller 180 may determine an image to be output based on the positions of the ends bent to the outside of both ends of the flexible display unit 251. For example, as illustrated in (b) of FIG. 7A, when the position of the outwardly bent stage is located at the left side, the controller 180 may output an image having a faster output order than any one of the images 510. 500) can be output.

In addition, the controller 180 may detect that the position of the bent end of the flexible display unit 251 is changed. For example, as shown in (b) and (c) of FIG. 7A, the controller 180 may detect that the position of the bent outwardly is changed from left to right.

In this case, the controller 180 may again output any one image 510 whose output order is later than that of the image 500 having the faster output order. That is, the controller 180 can move the images in the output order based on the position of the bend outwardly.

That is, the controller 180 outputs screen information of one of screen information having a slow output order or screen information having a quick output order according to the positions of the ends bent to the outside of the overlapped ends of the flexible display unit 251. The flexible display unit 251 may be controlled to be controlled.

Meanwhile, although the mobile terminal may determine screen information displayed on the flexible display unit 251 using the bending characteristic of the terminal, the present invention determines screen information based on a touch on the flexible display unit 251. Can also

In this case, the flexible display unit 251 may further include a touch sensor to enable touch. In this case, the touch sensor may be a sensor that can be changed in shape with bending of the flexible display unit 251.

The controller 180 may determine screen information to be displayed on the flexible display unit 251 based on a touch applied to the flexible display unit 251.

For example, as illustrated in (a) of FIG. 7B, in the state in which any image 500 is displayed on the flexible display unit 251, the controller 180 may control the flexible display unit 251. A drag input from right to left on the screen can be detected. In this case, as illustrated in (b) of FIG. 7B, the controller 180 may output the screen information 510 whose output order is later than that of any one, based on the direction of the drag input.

On the contrary, as shown in (b) of FIG. 7B, the controller 180 may sense a drag input from left to right on the flexible display unit 251. In this case, as shown in (c) of FIG. 7B, the controller 180 may again output any one screen information 500 having a faster output order than the screen information 510 having a late output order. .

Through this, the user may control the screen information displayed on the flexible display unit through various control commands.

Hereinafter, a method of controlling a function of an application running in the mobile terminal by using the bending characteristic of the flexible display unit 251 will be described. 8A, 8B, 8C, 8D, and 8E are conceptual views illustrating a method of controlling a function of an application running in a mobile terminal by using a bending characteristic of the flexible display unit 251.

The controller 180 may control a function of the running application by using the bending characteristic of the flexible display unit 251 with respect to the application currently running in the mobile terminal.

More specifically, when the application currently running in the mobile terminal is an application related to music playback, the controller 180 may control a playback function of an application related to music playback. Here, the playback function may mean all functions related to music playback, such as a previous song play, a next song play, a play stop function, and a play start function.

For example, as illustrated in (a) of FIG. 8A, an application related to music playback may be running in the mobile terminal. In this case, the controller 180 may perform different functions according to the positions of the ends bent outward of both ends of the flexible display unit 251.

For example, as illustrated in (b) of FIG. 8A, the controller 180 may play a previous song of music currently being executed when the outwardly curved stage is located at the left side. On the contrary, as shown in (c) of FIG. 8A, when the outwardly curved stage is located at the right side, the controller 180 can play the next song of the music currently being executed. Here, the flexible display unit 251 is more intuitive to the user by mapping a function of playing the previous song when the outward curved stage is left and playing the next song when the outward curved stage is the right. It can provide the environment for use.

That is, the user can simply play the previous song and the next song by simply folding the flexible display unit 251. On the other hand, in the drawing, the control in the state in which the screen information is displayed on the flexible display unit 251 has been described, but in the state that the illumination of the flexible display unit 251 is turned off, that is, the state in which the screen information is not displayed, the same Will be applicable. For example, a function that does not require visual information, for example, a music playback function, is currently executed according to the bending characteristic of the flexible display unit 251 without visual information displayed on the flexible display unit 251. You can control which functions are in progress.

The foregoing description has been described with respect to a case where the flexible display unit 251 is bent in an unfolded state. Hereinafter, a case where the position of the bent end that is outwardly changed while the flexible display unit 251 is bent will be described.

The controller 180 may have a function currently being executed in a state where the flexible display unit 251 is bent. In this case, the controller 180 may detect that only the bending characteristic of the flexible display unit 251 is changed while the posture of the mobile terminal is fixed. The controller 180 may control a function currently being reproduced when the bending characteristic is changed.

For example, as illustrated in (a) of FIG. 8B, the controller 180 may play music in a state in which the flexible display unit 251 is folded. In this case, as shown in (b) of FIG. 8B, the control unit 180 may change the position of the bent outward. In this case, the controller 180 can play the next song of the music currently being played. That is, the controller 180 can control a function currently being executed by changing the position of the bent end to the outer group.

In addition, the controller 180 may sense that the position of the bent end is changed by changing the posture of the mobile terminal while the bent state of the flexible display unit 251 is fixed.

More specifically, when the mobile terminal is bent outward from the first posture to the left, when the posture of the mobile terminal is changed to the second posture, the controller 180 may determine the rightward bent to the right.

For example, as illustrated in (a) and (b) of FIG. 8C, the controller 180 may detect that the posture of the mobile terminal is changed from the first posture to the second posture. In addition, the controller 180 can detect that the end curved outwardly is changed from left to right. In this case, the controller 180 may control a function of an application related to the native music of the music to play the next song of the music currently being played.

On the other hand, while the flexible display unit 251 is bent, during execution of a specific function, the flexible display unit may be switched to a non-bent state. Here, the non-bent state may mean that the front surface of the flexible display unit 251 is flat. In this case, the controller 180 may terminate execution of a specific function currently being executed.

For example, referring to (a) and (b) of FIG. 8D, while the current flexible display unit 251 is bent, music may be currently playing on the mobile terminal. In this case, the controller 180 may detect that the flexible display unit 251 is changed into a flat state in a curved state. In this case, the controller 180 may stop playing the music being played.

In addition, the controller 180 may perform different functions as the posture of the mobile terminal is changed while the flexible display unit 251 is bent. Here, the attitude of the mobile terminal may be measured at an angle inclined clockwise with respect to a reference line based on a direction coinciding with the gravity direction. For example, as illustrated in (b) of FIG. 8E, the controller 180 may measure an angle at which the mobile terminal is inclined based on the reference line a-a ′.

In addition, the different functions may be functions related to an application currently running in the mobile terminal. For example, in the current mobile terminal, when an application related to music playback is running, different functions may include a volume control function, an interval repeat function, and the like.

For example, as illustrated in (a) and (b) of FIG. 8E, the controller 180 may detect a change in posture of the mobile terminal while the flexible display unit 251 is bent.

In this case, when it is detected that the mobile terminal is inclined more than a preset angle with respect to the reference line a-a ', the controller 180 repeats the preset time section based on the currently playing time point. Can be done.

Through this, the user may control a function being executed in the mobile terminal only by rolling the flexible display unit 251 without a separate control command.

The present invention described above can be embodied as computer readable codes on a medium in 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 computer-readable media include hard disk drives (HDDs), solid state disks (SSDs), silicon disk drives (SDDs), ROMs, RAMs, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, and the like. This also includes implementations in the form of carrier waves (eg, transmission over the Internet). In addition, the computer may include the controller 180 of the terminal. Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
