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

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

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection fluorescent light sensor, a mirror reflection fluorescent light 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 electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

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

Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

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

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen).

Touch can be sensed.

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

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

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

Another example of an accessory is a touch pen for supplementing or extending a touch input to the touch screen.

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

2 is a conceptual diagram for explaining another example of the mobile terminal 100 according to the present invention.

As shown, the display unit 151 may be configured to be deformable by an external force. The deformation may be at least one of warping, bending, folding, twisting, and curling of the display unit 151. The deformable display unit 151 may be referred to as a " flexible display unit ". Here, the flexible display unit 151 may include both a general flexible display and an electronic paper (e-paper) or a combination thereof. In general, the mobile terminal 100 may include features of the mobile terminal 100 of Figures 1A-1C or similar features.

A typical flexible display refers to a sturdy display that is lightweight and does not break easily, such as paper, formed on a thin, flexible substrate that can flex, bend, fold, twist, or curl like a conventional flat panel display.

In addition, the electronic paper is a display technology to which general ink characteristics are applied, and the point that the reflected light is used is different from the conventional flat panel display. The electronic paper can be changed by using a twist ball or electrophoresis (electrophoresis) using a capsule.

The display area of the flexible display unit 151 becomes a flat surface in a state in which the flexible display unit 151 is not deformed (for example, a state having an infinite radius of curvature, hereinafter referred to as a first state). In the first state, the display area may be a curved surface in a state deformed by an external force (for example, a state having a finite radius of curvature, hereinafter referred to as a second state). As shown in the figure, the information displayed in the second state may be time information output on the curved surface. Such visual information is realized by independently controlling the emission of a sub-pixel arranged in a matrix form. The unit pixel means a minimum unit for implementing one color.

The flexible display unit 151 may be placed in a bent state (for example, a state in which the flexible display unit 151 is bent up and down or left and right) rather than a flat state in the first state. In this case, when an external force is applied to the flexible display unit 151, the flexible display unit 151 can be deformed into a flat state (or a less bent state) or a more bent state.

Meanwhile, the flexible display unit 151 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made to the flexible touch screen, the control unit 180 (see FIG. 1A) can perform control corresponding to the touch input. The flexible touch screen may be configured to sense the touch input in the first state as well as the second state.

Meanwhile, the mobile terminal 100 according to the present modification may be provided with a deformation sensing means for sensing deformation of the flexible display unit 151. [ The deformation detecting means may be included in the sensing unit 140 (see FIG. 1A).

The deformation detecting unit may be provided in the flexible display unit 151 or the case so as to sense information related to the deformation of the flexible display unit 151. Here, the information related to the deformation may be the direction in which the flexible display unit 151 is deformed, the degree of deformation, the deformation position, the deformation time, and the acceleration at which the deformable flexible display unit 151 is restored, In addition, the information can be various information that can be detected due to warping of the flexible display unit 151.

The control unit 180 may change the information displayed on the flexible display unit 151 based on the information related to the deformation of the flexible display unit 151 sensed by the deformation sensing unit, It is possible to generate a control signal for controlling the function of the controller.

Meanwhile, the mobile terminal 100 according to the present modification may include a case 201 that accommodates the flexible display unit 151. The case may be configured to be deformable together with the flexible display unit 151 by an external force in consideration of the characteristics of the flexible display unit 151. [

In addition, the battery (not shown) included in the mobile terminal 100 may be configured to be deformable together with the flexible display unit 151 by an external force in consideration of the characteristics of the flexible display unit 151. In order to implement the battery, a stack and folding method in which battery cells are stacked on top of one another may be applied.

The state change of the flexible display unit 151 is not limited to the external force. For example, when the flexible display unit 151 has the first state, it may be transformed to the second state by a command of the user or the application.

Hereinafter, the flexible display unit 151 according to the present invention will be described in more detail with reference to the accompanying drawings. Hereinafter, the flexible display unit 151 will be referred to as a 'flexible display 151'.

FIGS. 3A, 3B, 3C, 4A, 4B and 4C are conceptual diagrams for explaining a flexible display according to the present invention.

Referring to FIG. 3A, the flexible display 151 related to the present invention can be bent, bent, folded, twisted, or curled at least partly by an external force. In the present specification, any one of warping, bending, folding, twisting, and curling will be used, and the content containing the corresponding expression will be applicable to the remaining expressions in the same or similar manner.

The flexible display according to the present invention can be folded on the basis of the imaginary line l, as shown in Fig. 3A. The virtual line 1 can be fixedly disposed at a specific position when the mobile terminal 100 or the flexible display according to the present invention is manufactured. However, the present invention is not limited to this, and the virtual line folded by the flexible display may be variable.

In addition, the virtual line 1 may be one or a plurality of virtual lines. When there are a plurality of the virtual lines 1, the flexible display 151 can be folded a plurality of times.

The imaginary line 1 may be formed vertically with respect to one edge (e.g., the lower edge) of the flexible display, or may be formed by twisting to have a certain angle.

The imaginary line (l) may be formed so that the flexible display can be folded in the horizontal direction or folded in the vertical direction.

3A, when an external force is applied in any one direction, the flexible display 151 is flexibly displaced relative to the imaginary line 1 as shown in FIG. 3A (b) The portion 151a of the display portion and the remaining portion 151b can be folded to form a specific angle?. The specific angle? May have an omnidirection (0 degrees to 360 degrees), for example. If the specific angle [theta] is 360 degrees, the flexible display may be flat and unfolded. In addition, when the specific angle? Is 0 degree, the flexible display may be in a folded state such that the first portion 151a and the second portion 151b of the flexible display are in contact with each other.

In other words, when the external force is applied to the flexible display 151, the second portion 151b of the flexible display 151 (i.e., the first portion 151a of the flexible display 151) The second portion adjacent to the portion 151a) can be relatively rotated in the direction in which the external force is applied.

3B, a flexible display 151 according to the present invention includes a region A (or a bending region or a folding region A) of the flexible display 151, ) Can be bent (or bent).

Specifically, the flexible display 151 can be bent by an external force to form a specific radius of curvature with respect to the central axis of the one area (A).

In this case, a portion of the first portion 151a of the flexible display 151 and a portion of the second portion 151b of the flexible display 151 may be bent.

In this case, the angle [theta] between the first portion 151a and the second portion 151b of the flexible display 151 is set such that an imaginary line extending from a flat portion of the first portion 151a, May be defined as the angle between imaginary lines extending from the flat portion of the first portion 151b.

The relative rotation of the first and second portions of the flexible display 151 described herein will be applicable even when one region A of the flexible display is bent, as shown in Fig. 3B.

One area A in which the flexible display 151 is bent can be fixedly disposed at a specific position when the mobile terminal 100 or the flexible display according to the present invention is manufactured. However, the present invention is not limited to this, and an area A in which the flexible display 151 is bent may be variable.

The one region A may be one or a plurality of regions. When there is a plurality of one area A, the flexible display 151 may be formed to be able to bend in a plurality of sections.

The one area A may be formed vertically with respect to one edge (for example, the lower edge) of the flexible display, or may be formed by twisting to have a certain angle.

The one area A may be formed to allow the flexible display to bend in the horizontal direction or to be able to bend in the vertical direction.

The size of the area A in which the flexible display 151 is bent may be constant or may vary depending on the extent to which the flexible display 151 is bent. For example, the size of the one area A is determined by the degree of bending of the flexible display (or the degree of relative rotation of the second part 151b relative to the first part 151a of the flexible display 151) The smaller the angle between the first portion 151a and the second portion 151b becomes).

Hereinafter, for convenience of explanation, the flexible display 151 related to the present invention will be described with reference to an example in which a virtual line is folded as shown in FIG. 3A. However, as described with reference to FIG. 3B, the same or similar analogy can be applied to a case where one area A of the flexible display 151 is bent.

3C, the flexible display 151 associated with the present invention may be folded such that the first portion 151a of the flexible display and the second portion 151b adjacent the first portion form a predetermined angle (Or can be bent).

The predetermined angle may be at least one (or a plurality) as shown in FIG. 3C. For example, the flexible display 151 is fixed in a folded state such that the angle between the first portion 151a and the second portion 151b of the flexible display is a first angle? 1 by an external force And may be fixed in a folded state so as to have a second angle? 2 different from the first angle.

If the external force is not applied to the flexible display 151 in a state where the angle between the first and second portions 151a and 151b is changed by an external force to have an angle other than the predetermined angle, Any one of the first and second portions 151a and 151b may be relatively rotated so as to have any one of the set angles. That is, the flexible display according to the present invention may have elasticity (or tension, restoring force, etc.) so that folding is maintained at a predetermined angle (or a specific angle).

For example, as shown in FIG. 3C, in a state in which the angle between the first portion 151a and the second portion 151b of the flexible display is fixed to have the second angle? 2, When the external force is interrupted before the first angle? 1 or the third angle? 3 is changed, the first portion 151a and the second portion 151b of the flexible display change the inter- (or can be returned) to be the angle? 2. In this case, it can be understood that it is possible to fold the flexible display 151 at at least one (or a plurality of) predetermined angles.

However, the present invention is not limited to this, and the flexible display 151 according to the present invention may be configured such that the first display portion 151a and the second display portion 151b of the flexible display have a predetermined angle, When the external force is interrupted, it may be fixed to maintain the arbitrary angle. In this case, it can be understood that the flexible display 151 can be fixed at all angles, rather than fixed at only a predetermined angle.

Hereinafter, with reference to FIGS. 4A to 4C, a description will be given of an embodiment of a structure of a mobile terminal according to the present invention, which is formed such that the flexible display 151 can be folded or bent as described in FIGS. 3A to 3C Let's look at it.

The flexible display 151 is formed to be capable of bending or folding. Here, the folding refers to a state in which a radius of curvature of a part of the body of the mobile terminal is kept smaller than a reference value, and in other words, it corresponds to a folded state. In the case of folding, the screens of the display unit 151 are brought into contact with or close to each other.

In contrast, bending refers to a state in which a radius of curvature of a part of the body of the mobile terminal is maintained to be greater than the reference value, that is, a bent state.

Folding and bending may also be distinguished by the degree of bending. For example, if the angle between the first and second portions of the flexible display is bent so as to have an angle smaller than the predetermined angle, folding is defined as folding, and the bent portion is bent to have an angle equal to or greater than the predetermined angle. It can be defined as ground bending. Also, even when the bending is made to have an angle smaller than a predetermined angle, bending can be defined when the radius of curvature is larger than the reference value.

4A, when the flexible display 151 forms a single plane, at least a part of the display unit 151 is in a state in which the shape is changed . ≪ / RTI > As shown in FIG. 4A, the flexible display 151 may be folded and folded. That is, the display unit 1510 displays the first state (see FIG. 4A) in which the specific region is flat and the second state (see FIG. 4A) in which the specific region is folded in the curved surface, Lt; / RTI >

The connection portion 1030 may be configured such that the angle between the first portion 151a and the second portion 151b of the flexible display 151 is at least one predetermined angle (or all angles) (Or at all angles) so as to be able to be fixed at a predetermined angle.

The magnets 1032a and 1032b may be provided so as to maintain (fix) the magnets 1032a and 1032b in a straight line.

The first body part 1012 and the second body part 1022 are formed in the first and second body parts 1012 and 1022 so that the flexible display 151 can be maintained in a folded state. May be provided with magnets 1034a, 1034b that secure the magnet 1024 to overlap at an adjacent distance.

In another embodiment, the mobile terminal 100 according to the present invention may be provided with a hinge 1060 capable of adjusting the angle between the first body part and the second body part. The hinge 1060 may be referred to as a connecting portion, a fixing portion, or the like.

The first body part and the second body part may be relatively rotated with respect to the hinge 1060.

The hinge 1060 may be provided with a locking protrusion and a locking groove so that the first body part and the second body part can be fixed so that the angle between the first body part and the second body part has at least one predetermined angle . In addition, the hinge 1060 may include at least two gears, or an elastic spring, so that the first body part and the second body part can rotate relative to each other.

In the mobile terminal related to the present invention, change detection means (for example, rotation sensor, hall sensor, etc.) may be provided. The change detecting means may be a connection portion (or a hinge) itself, or may be a separate sensor.

The control unit 180 may use the change detection means to detect an angle between the first body part and the second body part (or an angle between the first part 151a and the second part 151b of the flexible display, The degree to which the display is bent or folded).

In addition, the mobile terminal according to the present invention may employ a structure capable of bending or folding the flexible display 151 in various manners, such that the angle between at least two portions of the flexible display 151 is at an angle (Or so that the bent region of the flexible display 151 has a radius of curvature).

In addition, the degree of bending or folding of the flexible display 151 can be changed not only by an external force but also by the mobile terminal itself through electrical control.

Hereinafter, various embodiments of the present invention using the above-described flexible display will be described in more detail with reference to the accompanying drawings.

FIG. 5 is a flowchart for explaining a typical control method of the present invention, and FIGS. 6, 7, 8, 9, and 10 are conceptual diagrams for explaining the control method shown in FIG.

First, the control unit 180 of the mobile terminal 100 related to the present invention can output screen information to the flexible display 151. [ The screen information may include various information that can be output to the flexible display 151. For example, the screen information may include a home screen page, a web page, an application execution screen, and a setting screen (setting menu).

The screen information may be output to the entire area of the flexible display 151 or may be output to at least a part of the area.

For example, the control unit 180 can output the screen information to the entire area of the flexible display 151 in a state where the flexible display 151 is flat. In this state, when the second portion 151b is relatively rotated with respect to the first portion 151a of the flexible display 151 (i.e., one area of the flexible display 151 is bent or folded) due to an external force, The screen information may be output to any one of the first and second portions 151a and 151b. For example, if the first portion is horizontally placed on the ground and the second portion is relatively rotated by a certain angle with respect to the first portion, the screen information may be output to the second portion.

The sizes of the first portion 151a and the second portion 151b may be the same or different.

When the screen information is outputted to the second part as the second part is relatively rotated, the first part may be turned off or other screen information (for example, a keypad) may be displayed.

5, the angle between the first portion 151a of the flexible display 151 and the second portion 151b adjacent to the first portion 151b forms an angle, 151 is bent, a step of outputting the screen information to the flexible display (for example, the second part) proceeds (S510).

Specifically, when the flexible display 151 is folded to form an angle, the control unit 180 determines whether the two portions (the first portion 151a and the second portion 151b) partitioned by the folded virtual line The screen information can be output to at least one (e.g., the second portion 151b).

Thereafter, in the present invention, when the second portion is relatively rotated with respect to the first portion by an external force, the screen information is controlled in different ways based on the direction in which the second portion is relatively rotated (S520).

The fact that the second portion is relatively rotated with respect to the first portion means that the flexible display is bent or folded relative to the imaginary line (or bending region) between the first and second portions of the flexible display 151 It may include the meaning of expanding.

That is, the flexible display 151 related to the present invention may include a first portion 151a and a second portion 151b adjacent to the first portion 151a. In addition, the flexible display 151 may be formed such that the second portion 151b is relatively rotatable with respect to the first portion 151a. The opposite is true.

The controller 180 controls the second portion 151b to be in contact with the second portion 151b by an external force in a state in which the flexible display is bent such that the angle between the first portion 151a and the second portion 151b forms an angle, The display information output to the flexible display can be controlled in different manners based on the direction in which the second portion 151b relatively rotates when the first portion 151a is relatively rotated.

The control unit 180 may perform a first function related to the screen information when the second part 151b is relatively rotated in the first direction with respect to the first part 151a. When the second portion 151b is relatively rotated in the second direction opposite to the first direction with respect to the first portion 151a, the controller 180 controls the second function Can be performed.

The first and second functions may include all kinds of functions that can be performed in the mobile terminal. When the angle between the first portion 151a and the second portion 151b of the flexible display 151 is bent to form an angle, the screen information is outputted to the second portion 151b . For example, the first portion 151a may be horizontally placed on the ground, and the second portion 151b may be relatively rotated with respect to the first portion 151a.

For example, when the screen information 600 output to the second portion 151b (or the flexible display) is screen information that can be enlarged or reduced as shown in Figs. 6A to 6C, The first function may be a function 600a for enlarging the screen information (or a zoom in function or an enlargement function), and the second function may be a function 600b for reducing the screen information Zoom out function, reduction function).

In other words, when the angle between the first portion 151a and the second portion 151b of the flexible display 151 is bent at an angle and the screen information is output to the second portion 151b When the second portion 151b is relatively rotated in the first direction p with respect to the first portion 151a by an external force (for example, when the flexible display 151 is further bent ), The screen information output to the second part 151b can be enlarged (600a) as shown in FIG. 6 (b).

When the second portion 151b is relatively rotated in the second direction q different from the first direction p with respect to the first portion 151a by an external force (For example, when the flexible display 151 is expanded)), the screen information output to the second portion 151b can be reduced as shown in FIG. 6 (c).

The screen information can be enlarged or reduced in various ways. For example, the control unit 180 may enlarge or reduce the screen information about the center of the screen information output to the second portion 151b of the flexible display (in other words, the first function or the second function Function can be performed).

7, the controller 180 controls the second portion 151b so that the second portion 151b is touched by the external force in a state in which the first region 710 of the second portion 151b is touched, (For example, enlarging function) or performing the second function (for example, a reducing function) around one area 710 to which the touch is applied, can do.

For example, as shown in FIG. 7A, when the flexible display is further folded in a state where a portion of the second portion 151b is touched (or the second portion 151b is touched) (B) of FIG. 7), the screen information 151b outputted from the second part 151b is displayed on the display screen of the second part 151b as shown in FIG. 7 (b) (700) on the basis of one area (710) to which the touch is applied.

If the screen information is an image and an area corresponding to a face is included in the image, the controller 180 determines that the second portion 151b of the flexible display is the first portion 151a, (Enlarging function) or a second function (reducing function) on the basis of the area corresponding to the face, based on the relative rotation based on the relative rotation based on the face.

Meanwhile, the mobile terminal related to the present invention can perform various functions based on further folding (or further bending) and expanding of the flexible display.

8, when the second portion 151b of the flexible display 151 is relatively rotated in the first direction with respect to the first portion 151a by an external force, for example, , It is possible to scroll the screen information output to the flexible display 151 (or the second portion 151b) in one direction.

On the contrary, when the second portion 151b of the flexible display 151 is relatively rotated in the second direction opposite to the first direction with respect to the first portion 151a by the external force, The screen information output to the display 151 (or the second portion 151b) can be scrolled in a direction opposite to the one direction.

For example, when the second portion 151b is relatively rotated in the p direction with respect to the first portion 151a (i.e., when the flexible display 151 is further bent) Direction.

As another example, when the second portion 151b is relatively rotated in the q direction with respect to the first portion 151a (i.e., the flexible display 151 (see Fig. 8 ) Is expanded, the screen information can be scrolled in the upward direction.

On the other hand, when the second portion 151b of the flexible display 151 is restored to a state before relative rotation, the controller 180 may stop scrolling the screen information.

That is, the control unit 180 determines that the first and second portions 151a and 151b of the flexible display have the first angle? 1 and the second angle? When the angle is changed to have the angle [theta] 2 (i.e., when the flexible display is bent or stretched), the screen information can be scrolled.

8 (b) and 8 (c), when the angle between the first portion 151a and the second portion 151b of the flexible display is changed from the second angle? 2 to the second angle? The control unit 180 may stop scrolling the screen information if it is restored to have the first angle [theta] 1 (or, if changed, bent or expanded).

The scroll speed may be proportional to the rate at which the second portion of the flexible display rotates relative to the first portion.

Meanwhile, the controller 180 of the mobile terminal according to the present invention can output different screen information to the flexible display according to the degree of bending of the flexible display.

For example, as shown in FIG. 9A, when the angle between the first portion 151a and the second portion 151b of the flexible display is the first angle? 1 , The first display information 900a can be output to the flexible display 151 (for example, the second portion 151b).

9 (b), the controller 180 determines whether the angle between the first portion 151a and the second portion 151b of the flexible display is greater than the angle of the first portion < RTI ID = 0.0 > (For example, the second portion 151b), when the second screen information 900b is changed to the second angle? 2 different from the first angle, can do.

Here, the first screen information 900a and the second screen information 900b can be any screen information as long as they are different screen information. For example, the first screen information 900a is an image before correction , And the second screen information 900b may be an image after the correction.

On the other hand, the control unit 180 of the mobile terminal according to the present invention can control a moving picture being output (played back) to the flexible display based on the flexible display being bent or spread by an external force.

For example, as shown in FIG. 10A, in a state in which a moving image is being reproduced on the flexible display 151 (for example, the second portion 151b of the flexible display) (Stop, pause, stop) the reproduction of the moving picture when the angle between the first portion 151a and the second portion 151b of the flexible display is changed by the external force. For example, when the bent flexible display 151 is expanded by an external force, the control unit 180 can stop the moving picture being played back on the flexible display 151. [ In the opposite case, the same / similar analogy can be applied.

10 (b) and (c), when the angle between the first portion 151a and the second portion 151b of the flexible display is changed to the previous angle, The still video can be reproduced again.

For example, when the angle between the first portion 151a and the second portion 151b of the flexible display is changed to the second angle? 2 by the external force in a state having the first angle? 1, ) Can stop the moving picture being played back.

The control unit 180 determines whether the angle between the first portion 151a and the second portion 151b of the flexible display is changed (restored) from the second angle? 2 to the first angle? The still video can be reproduced again.

If the control unit 180 determines that the angle between the first portion 151a and the second portion 151b of the flexible display is changed from the second angle? 2 to the third angle instead of the first angle, (Or image) to the flexible display 151 (for example, the second portion 151b), to terminate the moving image being output, or to turn off the flexible display.

The above description can be performed, for example, when the angle between the first portion and the second portion of the flexible display which is changed by the external force is equal to or greater than the reference angle. In other words, when the angle between the first and second portions is changed to be equal to or smaller than the reference angle, the control unit 180 can restrict the execution of the functions described in Figs. 6 to 10. For example, referring to FIG. 6, the control unit 180 determines whether or not the screen information output to the flexible display 151 and the screen information And can perform the associated first function or second function.

As another example, the above description may be performed when the speed at which the second portion is relatively rotated relative to the first portion by an external force is equal to or higher than a predetermined speed. In other words, the control unit 180 can restrict the execution of the functions described in Figs. 6 to 10 when the relative speed is not higher than a predetermined speed. For example, referring to FIG. 6, the controller 180 controls the flexible display 151 based on the relative speed at which the second portion is relatively rotated relative to the first portion, And can perform a first function or a second function related to the outputted screen information.

As another example, the above description can be performed when the radius of curvature of the bent region of the flexible display is changed by an external force to be larger than a reference value. In other words, when the radius of curvature is changed to be smaller than or equal to the reference value, the control unit 180 can restrict the execution of the functions described in Figs. 6 to 10.

The above description can be applied to the functions described in Figs. 7 to 10, as well as Fig. 6, in a similar or analogous manner.

As described above, according to the present invention, the present invention can provide a new user interface capable of controlling the screen information displayed on the flexible display in an optimized manner only by bending or stretching the flexible display.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
