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

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

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

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

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

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

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

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

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

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

In some cases, electronic components may also be mounted on the rear case 102. Electronic parts that can be mounted on the rear case 102 include detachable batteries, an identification module, a memory card, and the like. In this case, a rear cover 103 for covering the mounted electronic components can be detachably coupled to the rear case 102. Therefore, when the rear cover 103 is separated from the rear case 102, the electronic parts mounted on the rear case 102 are exposed to the outside.

As shown, when the rear cover 103 is coupled to the rear case 102, a side portion of the rear case 102 can be exposed. In some cases, the rear case 102 may be completely covered by the rear cover 103 during the engagement. Meanwhile, the rear cover 103 may be provided with an opening for exposing the camera 121b and the sound output unit 152b to the outside.

These cases 101, 102, and 103 may be formed by injection molding of synthetic resin or may be formed of metal such as stainless steel (STS), aluminum (Al), titanium (Ti), or the like.

The mobile terminal 100 may be configured such that one case provides the internal space, unlike the above example in which a plurality of cases provide an internal space for accommodating various electronic components. In this case, a unibody mobile terminal 100 in which synthetic resin or metal is connected from the side to the rear side can be realized.

Meanwhile, the mobile terminal 100 may include a waterproof unit (not shown) for preventing water from penetrating into the terminal body. For example, the waterproof portion is provided between the window 151a and the front case 101, between the front case 101 and the rear case 102, or between the rear case 102 and the rear cover 103, And a waterproof member for sealing the inside space of the oven.

The terminal body may be provided with at least one antenna for wireless communication. The antenna may be embedded in the terminal body or formed in the case. For example, an antenna constituting a part of the broadcast receiving module 111 (see FIG. 1A) may be configured to be able to be drawn out from the terminal body. Alternatively, the antenna may be formed in a film type and attached to the inner surface of the rear cover 103, or a case including a conductive material may be configured to function as an antenna.

The terminal body is provided with a power supply unit 190 (see FIG. 1A) for supplying power to the mobile terminal 100. The power supply unit 190 may include a battery 191 built in the terminal body or detachable from the outside of the terminal body.

When the battery 191 is detachably attached to the terminal body, the rear cover 103 may be detachably coupled to the rear case 102.

The mobile terminal 100 may be provided with an accessory that protects the appearance or supports or expands the function of the mobile terminal 100. [ One example of such an accessory is a cover or pouch that covers or accommodates at least one side of the mobile terminal 100. [ The cover or pouch may be configured to interlock with the display unit 151 to expand the function of the mobile terminal 100. 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 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 warping, bending, folding, twisting, and curling of the display portion 251. The deformable display portion 251 may be referred to as a " flexible display portion ". Here, the flexible display unit 251 may include both a general flexible display, e-paper, and combinations thereof. In general, mobile terminal 200 may include features of 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.

In a state in which the flexible display portion 251 is not deformed (for example, a state having an infinite radius of curvature, hereinafter referred to as a first state), the display area of the flexible display portion 251 is flat. 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 251 may be placed in a bent state (for example, a vertical state or a left-to-right bent state) instead of a flat state in the first state. In this case, if an external force is applied to the flexible display portion 251, the flexible display portion 251 may be deformed into a flat state (or a less bent state) or a more bent 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 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 200 according to the present modification may be provided with a deformation detecting means capable of detecting deformation of the flexible display unit 251. 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 251 or the case 201 to sense information related to the deformation of the flexible display unit 251. Here, the information related to the deformation may be the direction in which the flexible display unit 251 is deformed, the degree of deformation, the deformation position, the deformation time, and the acceleration at which the deformed flexible display unit 251 is restored, In addition, the flexible display unit 251 may be various information that can be detected due to the bending of the flexible display unit 251.

The control unit 180 may change the information displayed on the flexible display unit 251 or change the information displayed on the flexible display unit 251 based on the information related to the deformation of the flexible display unit 251, It is possible to generate a control signal for controlling the function of the controller.

Meanwhile, the mobile terminal 200 according to the present modification may include a case 201 that accommodates 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, the battery (not shown) included in the mobile terminal 200 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 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 251 is not limited to an external force. For example, when the flexible display unit 251 has the first state, it may be transformed to the second state by a command of the user or the application.

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

FIG. 3 is a flowchart illustrating a method of controlling a mobile terminal according to an exemplary embodiment of the present invention. FIGS. 4 to 9 illustrate a method of controlling a mobile terminal according to an exemplary embodiment of the present invention, And an operation screen. The mobile terminal according to the present invention may include a sensing unit 140, a flexible display unit 251 and a control unit 180. The control method may be performed under the control of the control unit 180 of the mobile terminal described with reference to FIG. Can be implemented.

3, in step S310, the sensing unit 140 senses a bending event of the flexible display unit 251 according to the control method of the mobile terminal 200 according to the present invention.

Specifically, the sensing unit 140 senses a deformation, that is, a bending event, which is generated when an external physical force is applied to the flexible display unit 251. The sensing unit 140 may sense information on bending of the flexible display unit 251 due to a bending event, that is, bending position, bending direction, bending size, bending holding time, or bending order.

For example, as information on the bending position, it is possible to detect at which position of the flexible display unit 251 the bending occurs and how many bending positions occur.

As another example, information regarding the bending direction can be detected as to whether the bending position is bent in the direction toward the front of the terminal body, or in the direction toward the rear side of the terminal body, or the like.

It is also possible to detect, as information on the warpage size, how much each warp position is warped or whether the degree of warpage of each warp position exceeds a predetermined value.

Also, as information on the bending holding time, it is possible to detect the time from the time when the bending occurs to the time when the bending occurs at each bending position.

Further, as the information on the bending order, it is possible to detect the order in which the bending occurs in each of the plurality of bending positions. For example, when warping occurs at the first position and the second position, it is possible to sense whether the warping first occurred at the first position, the first warped at the second position, or the warped at the same time.

Next, the control unit 180 proceeds to a step of controlling the favorite function related to the operation screen displayed on the flexible display unit 251 at the time when the bending event is detected (S320).

It should be noted that the operation screen displayed on the flexible display unit 251 may be diversified according to various functions implemented in the mobile terminal 200. [

For example, the operation screen displayed on the flexible display unit 251 may be a lock screen or a home screen screen displayed when the flexible display unit 251 is activated in the inactive state.

Alternatively, the operation screen displayed on the flexible display unit 251 may be a screen image on which an application program corresponding to the selected icon is driven and displayed as the control unit 180 receives an input for selecting a predetermined icon on the home screen screen .

For example, the action screen may be an internet screen, a contact screen, a photo album screen, or an email screen. The other operation screen may include a mobile banking screen, a memo screen, a messenger screen, a shot screen, a call screen, a message screen, a schedule screen, etc., and a predetermined application program is driven under the control of the controller 180 And is not particularly limited as long as it is a screen displayed on the flexible display unit 251.

The term " favorite function " of the present invention is a term encompassing a function of registering all or a part of information related to an operation screen or recalling previously registered information.

Such a favorite function may be different for each application program existing in the mobile terminal 200. [ For example, if the operation screen is an Internet screen accessed by a specific web site address, the application program related to the Internet screen is an Internet browser, and the favorite function of the Internet browser is a web site address of the Internet screen, Or a function of loading a list of favorite web sites registered with a predetermined web site address.

In another example, if the action screen is a contact screen, the application associated with the contact screen is a contact management application, and the favorite function of the contact management application is to save the contact displayed on the contact screen to the contact favorites list Or may be a function of bringing a predetermined contact to a pre-registered contact favorite list.

 For example, when the operation screen is a photo album screen, the application program related to the photo album screen is a photo management application, and the favorite function of the photo management application registers the photo displayed on the photo album screen in the photo favorite list, A photo may be a function to load a pre-registered photo favorites list.

For example, when the operation screen is an email screen, the application program related to the email screen is an email application, and the favorites function of the email application registers the email displayed on the email screen in the email favorites list, It may be a function to load a list of pre-registered e-mail favorites.

That is, 'favorites' in the present invention should be understood to relate not only to the address of the website but also to the registration of various information or the use of the pre-registered information list according to the purpose of the application program related to each of the different operation screens.

On the other hand, when controlling the favorite function related to the operation screen displayed on the flexible display unit 251 at the point of time when the bending event is detected, the control unit 180 determines whether the bending operation is performed based on the bending direction or / Control can be performed.

For example, if the bending direction of the bending event is the first direction, the control unit 180 can register the information displayed on the operation screen in the favorite list of the application program related to the operation screen. In this case, the first direction may be a direction toward the front surface of the terminal body, or a direction toward the rear surface of the terminal body.

On the contrary, if the bending direction of the bending event is the second direction, the controller 180 can display the favorites list of the application program related to the operation screen on the flexible display unit 251. [ In this case, the second direction may be a direction different from the first direction. For example, if the first direction is the direction toward the front surface of the terminal body, the second direction is the direction toward the rear surface of the terminal body, and if the first direction is the direction toward the rear surface of the terminal body, It may be a direction facing the front side.

Accordingly, the user can select the favorite function related to the specific operation screen by sequentially applying the external force so that the flexible display unit 251 is bent in the predetermined direction or the opposite direction on the specific operation screen And thus it is advantageous that user convenience is increased.

On the other hand, when the operation screen at the time when the bending event is sensed is a home screen screen, the controller 180 can perform control different from the case where the other screen is the operation screen. Unlike other operation screens, such as an internet screen, a contact screen, an album screen, or an e-mail screen, which are displayed on the flexible display unit 251 according to driving of an application program that manages or processes only information corresponding to a specific type, Information on various states of the mobile terminal 200 (e.g., battery remaining amount, phone call enabled state, Wi-Fi state, message reception state, etc.), various widgets and icons, etc. are displayed before the other operation screens are displayed This is because the operation screen is displayed.

Specifically, if the bending direction of the bending event is the third direction, and the operation screen displayed on the flexible display unit 251 at the time when the bending event is detected is the home screen screen, the control unit 180 determines that the bending of the third direction It is possible to display a favorite list of an application program pre-allocated to the flexure position at the flexible display unit 251. At this time, the third direction may be the same direction as either the first direction or the second direction described above.

That is, when a predetermined bending event occurs, a specific application program in which a favorite function is executed may be pre-allocated to a predetermined position of the flexible display unit 251. For example, when the home screen screen is displayed on the operation screen, when a bending event in the third direction with respect to a specific position (e.g., upper left corner) occurs, the control unit 180 displays the application program The contact favorite list of the contact management application can be displayed on the flexible display unit 251. [ At this time, if a bending event in the fourth direction other than the third direction occurs in the upper left corner, the controller 180 can ignore the bending event in the fourth direction.

In addition, when there are a plurality of bending positions of the bending events, the control unit 180 can simultaneously display the favorite lists of the plurality of application programs preliminarily assigned to the plurality of bending positions on the flexible display unit 251.

Although the control unit 180 has been described above as executing the favorite function of a specific application program based on the bending event, it is also possible to execute a function other than the favorite function.

For example, when an internet screen is displayed as an operation screen, if a predetermined warping event is detected, the controller 180 can execute an 'open new window' function.

For example, when the contact screen is displayed on the operation screen, if a predetermined bending event is detected, the control unit 180 can execute a 'call connection' function for the contact displayed at the top of the contacts displayed on the contact screen have.

For example, when the photo album screen is displayed on the operation screen, if a predetermined bending event is detected, the control unit 180 displays a 'share' function for the most recently photographed photo Can be executed. When the 'share' function is executed, the corresponding photo can be transmitted to the mobile terminal 200 of another person.

On the other hand, the setting information for the function (s) executed in response to the specific 'bending event' and the specific 'operation screen' at the time when the bending event is detected can be stored in the memory 170 of the mobile terminal 200 have. It goes without saying that the setting information stored in the memory 170 can be changed by a user's operation.

Hereinafter, a method of controlling the mobile terminal 200 according to an embodiment of the present invention will be described in detail with reference to FIGS. 4 to 13. FIG. For convenience of description, only the flexible display unit 251 is shown in Figs. 4 to 139 except for the case 201. Fig.

4 illustrates the warpage of the flexible display unit 251 according to a warp event. In the present invention, the bending event may be information on bending to a point at which the bending of the flexible display portion 251 is recovered to a state before the bending occurs at an arbitrary point in time.

The bending position of the bending event may be at least one position of the flexible display unit 251. [ For example, as shown in FIG. 4A, the bending position of the bending event may be a predetermined position 301 near one of the edges of the flexible display unit 251. Alternatively, the bending position of the bending event may be a plurality of bending positions. That is, the bending position may be two (301, 302) as shown in (b) of FIG. 4a, or four (301, 302, 303, 304) as shown in FIG. 4A shows that the bending position of the bending event is four positions including the vertexes of the flexible display 251. However, the present invention is not limited thereto, and the bending position may be deformed by an external force such as a corner or a center of the flexible display 251 It is not limited in particular.

The bending direction of the bending event may be a direction (hereinafter referred to as a first direction, indicated by a solid line) in which one position 301 faces the front surface of the terminal body, as shown in Fig. 4B. Alternatively, the bending direction of the bending event may be a direction (hereinafter referred to as a second direction, indicated by a dotted line) in which one position 301 faces the rear surface of the terminal body, as shown in Fig. 4B. However, the present invention is not limited to this, and it goes without saying that it can be bent in various directions by an external force. Hereinafter, for convenience of explanation, it is assumed that the bending direction of the bending event is directed to either the front side or the rear side of the terminal body.

On the other hand, when there are a plurality of bending positions of bending events, the bending directions of the bending positions 301 and 302 may be the same as each other as shown in FIG. 4B, or may be different as shown in FIG. 4B.

Further, when there are a plurality of bending positions, the bending order of each bending position (i.e., the bending order) can be detected as a bending event. For example, the sensing unit may be a bending event in which the bending of the plurality of bending positions 301 and 302 occurs at the same time, or the bending of the second bending positions 301 and 302 occurs after the bending occurs at the first position 301 as shown in Fig. It is possible to detect whether a warp occurs at the position 302 or a warp occurs at the first position 301 after the warp occurs at the second position 302 as shown in FIG. 4C. In FIG. 4C, it is assumed that there are two bending positions, but the same applies to more bending positions.

5 is a view referred to for explaining an operation screen displayed on the flexible display unit 251 at the time when a bending event is detected and a favorite function executed by the controller 180 accordingly.

Referring to FIG. 5, the operation screen displayed on the flexible display unit 251 may vary according to the function of the mobile terminal 200. 5, it is assumed that the bending positions of the bending events with respect to the flexible display unit 251 are all the same, and the bending direction is either the first direction or the second direction.

5A and 5B illustrate the case where the operation screen displayed on the flexible display unit 251 at the time when the bending event is detected is the Internet screen.

If the bending direction of the bending event is a first direction which is a predefined direction, the controller 180 transmits the web site address ('m.naver.com') of the Internet screen to the web site You can register in your favorites list. At this time, the controller 180 can display a message window 351 for informing that the web site address corresponding to the internet screen is registered as a bookmark on the flexible display unit 251 for a preset time as shown in (a) of FIG. have.

If the bending direction of the bending event is different from the first direction and is a second direction that is a predefined direction, the control unit 180 registers the predetermined website address as shown in FIG. 5A (b) The web site favorite list 361 can be displayed.

5A and 5B show a case where the screen displayed on the flexible display unit 251 at the time when a bending event is detected is a contact screen.

If the bending direction of the bending event is the first direction, the controller 180 can store the contact currently displayed on the contact screen in the contact favorite list as shown in FIG. 5B (a). At this time, the controller 180 may display a message window 352 for informing that the contact shown on the contact screen is registered in the contact favorite list on the flexible display unit 251 for a predetermined time, .

If the bending direction of the bending event is a second direction different from the first direction, the controller 180 displays a contact favorite list 362 in which a predetermined contact is registered in advance, as shown in FIG. 5B, Can be displayed.

FIGS. 5A and 5B show a case where the screen displayed on the flexible display unit 251 at the time when a bending event is detected is an album screen.

If the bending direction of the bending event is the first direction, the controller 180 may store the photograph currently displayed on the photo album screen in the photo album list as shown in FIG. 5C. At this time, the control unit 180 may display a message window 353 informing that the photographs shown on the photo album screen are registered in the photo favorite list, on the flexible display unit 251 for a predetermined time, .

If the bending direction of the bending event is a second direction other than the predefined first direction, the control unit 180 can display the photo favorite list 363 in which a predetermined photograph is already registered. At this time, each photograph of the photo favorites list 363 can be displayed in a thumbnail format as shown in Fig. 5C (b).

FIGS. 5A and 5B show a case where the screen displayed on the flexible display unit 251 at the time when a bending event is detected is an e-mail screen.

If the bending direction of the bending event is the first direction, the control unit 180 may store the e-mail currently displayed on the e-mail screen in the e-mail favorites list (e.g., important mail) as shown in Fig. At this time, the control unit 180 may display a message window 354 that informs that the email shown on the email screen is registered in the email favorite list, on the flexible display unit 251 for a predetermined time, .

If the bending direction of the bending event is a second direction different from the first direction, the control unit 180 also displays an email favorite list 364 (see FIG. 5D (b) ') Can be displayed.

On the other hand, if the operation screen at the time of detecting the first warp in one warp event and the operation screen at the time of detecting the restoration of all warp are different, the controller 180 displays the operation screen You can execute related Favorites function.

When the operation screen at the time of warping is different from the operation screen at the time when the warping is restored, the controller 180 can execute the favorite function related to the operation screen at the time when the warping is restored. For example, after the curvature of the operation screen of the music application is restored, when the curvature of the operation screen of the navigation application is displayed by the user's operation or the like, the control unit 180 displays the favorite list of the navigation application as a flexible And can be displayed on the display unit 251.

In the above description, it is assumed that a favorite function related to the operation screen displayed on the flexible display unit 251 according to execution of an application program (e.g., Internet browser) for managing and processing specific types of information such as the Internet, contacts, .

In the following, the favorite function executed by the control unit 180 when the operation screen is the home screen screen will be described.

FIGS. 6 and 7 are diagrams for explaining a function executed by the control unit 180 when the operation screen displayed on the flexible display unit 251 is the home screen screen at the time when the bending event is detected.

When the bending direction of the bending event is a predefined direction, the control unit 180 can display a list of favorite programs of the pre-allocated application program in the flexible display unit 251 in a predefined direction.

If the bending direction of the bending event is not a predefined direction, the control unit 180 does not display the favorites list of the pre-allocated application program at a predetermined position of the home screen screen, or can perform other functions.

6 and 7, it is assumed that the predefined direction in which the display function of the favorite list is executed is a first direction (indicated by a dotted line) for convenience of explanation.

For example, referring to FIG. 6A, when a bending event in which the first position 301 is bent in the first direction is detected, the controller 180 performs pre-allocation at a predetermined position of the flexible display unit 251 The favorite list 365 of the navigation application that is pre-assigned to the first location 301 of the applications.

6 (b), the control unit 180 detects the bending event that the second position 302 is bent in the first direction, and the control unit 180 controls the second position of the flexible display unit 251 A favorite list 366 of the 'music application' which is an application program previously allocated to the music application 302. The favorites list 366 of the 'music application' may include items for pieces of music that are registered in advance as favorite music.

6 (c), the controller 180 detects the bending event in which the third position 303 is bent in the first direction, so that the control unit 180 controls the third position of the flexible display unit 251 Mobile banking application ", which is an application program pre-allocated to the mobile banking application 303, At this time, the favorite list 367 of the mobile banking application may be a list of 'recent deposit account' as shown in (c) of FIG. However, this is an example, and the 'frequently used account' may be designated as the favorites list 367.

6 (d), the control unit 180 detects a bending event in which the fourth position 304 is bent in the first direction, the control unit 180 controls the fourth position of the flexible display unit 251 A favorite list 368 of the 'real estate search application' which is an application pre-assigned to the real estate search application 304 can be displayed. At this time, the favorites list 368 of the real estate search application may be displayed with the name 'interest real estate' as shown in (d) of FIG.

7 exemplifies a function executed by the control unit 180 when there are a plurality of bending positions of one bending event, unlike in Fig. At this time, it is assumed that the bending directions of the plurality of bending positions are the same in the first direction.

When the controller 180 detects a predefined bending event having a plurality of bending positions, the controller 180 displays a list of favorites for a plurality of application programs preliminarily allocated to each of the plurality of bending positions of the predefined bending event on the flexible display unit 251 at the same time.

For example, referring to FIG. 7A, when a bending event in which the first position 301 and the second position 302 of the flexible display unit 251 are bent is detected, A favorite list 371 ('favorite way' in FIG. 7 (a)) of the 'directions application' that is pre-assigned to the application 301 and an application program pre- The favorite list 372 ('favorite music' in FIG. 7 (a)) of the music application can be displayed together on the flexible display unit 251.

7A shows that the 'favorite way' list 371 is displayed at the top of the 'favorite music' list 372, but this is merely an example, and 'favorite music' It can also be displayed at the top of 'My favorites'.

7 (b), when a bending event in which the second position 302 and the fourth position 304 of the flexible display unit 251 are warped is detected, the control unit 180 controls the second A favorite list 373 ('favorite music' in FIG. 7B) corresponding to the favorite function of the 'music application', which is an application program preliminarily allocated to the location 302, The favorite list 374 ('interest real estate' in FIG. 7B) of the 'real estate search application', which is an allocated application, can be displayed together on the flexible display unit 251. 7B shows that the 'favorite music' list 373 is displayed at the top of the 'interesting real estate' list 374, but this is merely an example, and the 'interesting real estate list' Music 'at the top.

On the other hand, when the bending direction of the predetermined bending position does not correspond to the predefined direction, even if there are a plurality of bending positions of a single bending event, the control unit 180 determines that the pre- The list may not be displayed on the flexible display unit 251. [

For example, assuming that the control unit 180 detects a bending event in which the second position 302 and the third position 303 of the flexible display unit 251 are bent, as shown in FIG. 7C, The bending direction of the second position 302 may be a first direction which is a predefined direction while the bending direction of the third position 303 may be a predefined direction (e.g., a second direction).

In this case, the control unit 180 displays only the 'favorite music' list 375 of the 'music application', which is an application program pre-allocated to the second position 302 whose bending direction is the first direction, (E.g., a recent deposit account list) of the " mobile banking application ", which is an application pre-assigned to the third position 303 in the two directions. Accordingly, the screen displayed on the flexible display unit 251 in the case of FIG. 7C can be the same as that in FIG. 6B.

On the other hand, when the control unit 180 processes only a plurality of bending positions at the same time as one bending event, or detects a bending at a predetermined bending position and then bends the bending until all the bending positions are restored, It can be processed as an event. Alternatively, a bending event may be treated as a bending event from a moment when the bending is detected at a predetermined bending position to a bending position where bending occurs within a predetermined time.

8 is an example in which an application program is allocated to a predetermined area of the flexible display unit 251 by sensing a predefined bending event when the operation screen is a home screen screen.

When the control unit 180 detects a bending event having a predefined pattern (for example, the first position is bent and restored in the first direction) while the home screen screen is displayed as an operation screen as shown in FIG. 8A, , You can enter the application allocation mode. For example, if i) no application program is assigned to every position of the flexible display unit 251, ii) before an application program is assigned to some location, iii) if the pre- As a bending event with a predefined pattern is detected, such as when an application is changed to another application, the application-specific application allocation mode can be activated.

Specifically, when entering the application program allocation mode, the control unit 180 can display an application program list 381 assignable to a predetermined position of the flexible display unit 251 in one area of the home screen screen. The application program list 381 may be displayed in an icon form as shown in FIG. 8 (b), but this is merely an example, and the application program list 381 may be displayed in various formats such as a text format for guiding the application program name Of course.

At this time, the areas 391, 392, 393, and 394 corresponding to the positions (301, 302, 303, 304, , A predetermined visual effect (e.g., dotted line, highlight, shading, emphasis, etc.) may be applied to distinguish it from other areas. The control unit 180 may display the message window 382 on the flexible display unit 251 for a predetermined period of time to guide information (e.g., an operation method) related to the assignment of the application program.

8 (c), the control unit 180 receives a touch input for dragging (or sliding) the icon for the specific application (Internet browser) to the specific area 391 of the flexible display unit 251 , It is possible to control the specific area 391 to be assigned a specific application program (e.g., an Internet browser) as shown in FIG. 8 (d). At this time, the control unit can remove the icon for the specific application program (Internet browser) allocated to the specific area 391 from the application program list 381 as shown in FIG. 8 (d).

8 (c) of FIG. 8), the control unit 180 repeats the operation of each area 391, 392, 393, and 394 so that all the areas (e) of the flexible display unit 251 Different application programs can be assigned to the application programs. At this time, the control unit 180 may display a message window 383 indicating that the allocation of the application program is completed for a preset time.

8 (f), the control unit 180 can display the home screen image immediately before entering the application program allocation mode on the flexible display unit 251. [ 8 (f), as time required for the operations shown in Figs. 8 (a) to 8 (e) takes time, the time displayed on the home screen screen is changed from 2:30 pm to 2:00 pm 31 minutes.

In FIG. 8, there are four areas (391, 392, 393, and 394) to which an application program can be allocated, and application programs are allocated to all areas. However, this is only an illustrative example. That is, there may be fewer or more areas in which application programs can be allocated, and application programs may not be allocated in advance in all or some of the areas.

9 is an example of detecting a predefined bending event when the operation screen is a home screen screen and guiding information on an application program previously allocated to a predetermined area of the flexible display unit 251. [

When the control unit 180 detects a bending event having a predefined pattern (for example, the first position is bent and restored in the second direction) while the home screen screen is displayed as an operation screen as shown in FIG. 9A, , It is possible to enter a mode for guiding the information of the pre-allocated application program.

Specifically, when the user enters the guidance mode for the information of the pre-allocated application program, the control unit 180 determines whether the pre-allocated information is allocated for each of the areas 391, 392, 393, and 394, as shown in FIG. 9 (b) (E.g., an icon, an application program name, etc.) related to the application program can be displayed in each of the areas 391, 392, 393, and 394. The control unit 180 may control so that objects displayed for each area are displayed for a predetermined time and then disappear.

Here, the assignment of the specific application program to each of the areas 391, 392, 393, and 394 is performed through the above-described method or other method (e.g., key operation, touch input, voice command, etc.) .

9B, an Internet browser, a music application, a mobile banking application, and a map application may be allocated to the first to fourth areas 391, 392, 393, and 394 in order. However, it will be understood by those skilled in the art that this is merely an example and other application programs existing in the mobile terminal 200 can be allocated to the respective areas.

(396, 397, 398, 399) corresponding to the pre-allocated application program for each of the areas 391, 392, 393, 394 to the respective areas 391, 392, 393, 394, The control unit can give a predetermined visual effect to the object corresponding to the application program having no item registered in the favorite list or the area allocated with the application program.

For example, unlike the application programs assigned to the first, second and fourth areas 391, 392 and 394, the mobile banking application's favorites list, which is an application program assigned to the third area 393, It is assumed that the item (for example, a frequently used account) is not registered. In this case, as shown in FIG. 9 (b), the control unit displays the icon 398 corresponding to the mobile banking application displayed in the third area 393 as compared with the other icons 396, 397, and 399 Can be treated faintly. Accordingly, the user can immediately recognize whether an application program is allocated to each area and whether there is an item previously registered as a favorite list of the allocated application program, thereby improving user convenience.

Thereafter, the controller 180 may detect a predefined warping event and display a list of bookmarks of the pre-allocated application program in the area corresponding to the warping position of the detected warping event. For example, as shown in FIG. 9C, when a bending event is detected such that the second position 302, which is the bending position corresponding to the second area 392, is bent in the first direction, The favorite music list 400, which is a favorite list of music applications already allocated in the area 392, can be displayed on the flexible display unit 251 as shown in FIG.

10 is a diagram for explaining an example of changing the favorite list displayed on the flexible display unit 251 based on the touch input and the bending event.

First, when the control unit 180 receives a touch input of a predefined pattern for the flexible display unit 251 displaying a list of favorites of at least one application program, the favorite list corresponding to the touch input is displayed on the flexible display unit 251).

For example, when the 'Favorite Way' list 401 and the 'Favorite Music' list 402 are displayed together as shown in FIG. 10 (a), the 'Favorite Music' The controller 180 changes the 'favorite music' list 402 to a deletable state upon receiving a long press touch input that presses one point of the 'favorite music' for a preset time or more.

Then, in a state where the long press touch input is held, the touch input (e.g., sliding, swiping, or the like) pushing in a predetermined direction (e.g., left or right) The control unit 180 removes the 'favorite music' list 402 displayed on the flexible display unit 251 as shown in (c) of FIG. 10 . At this time, the control unit 180 can further control the favorite list of the specific application program not to be displayed on the flexible display unit 251, and can further initialize the favorite list itself. In addition, the control unit may display a message window 411 indicating that the favorite list of the specific application program has been removed on the flexible display unit 251 for a preset time.

On the other hand, if the long press touch input is released before receiving a touch input to be pushed in a predetermined direction (e.g., left or right), the control unit displays the 'favorite music' list 402 on the flexible display unit 251 ). ≪ / RTI >

10 (d), when the bending event occurs in which the fourth position 304 of the flexible display unit 251 is bent in the first direction, which is a predefined direction, Favorite Realty " list 403, which is a list of favorites of an application (e.g., a real estate search application) pre-assigned to the fourth location 304, can do.

11 is a diagram for explaining an example of changing a position between a plurality of favorite lists displayed on the flexible display unit 251 based on a touch input.

When the controller 180 receives a touch input of a predefined pattern with respect to the flexible display unit 251 showing a list of favorites of at least one application program, the controller 180 changes the positional relationship between the favorite lists based on the touch input .

For example, as shown in (e) of FIG. 9, when the 'favorite way' list 401 is displayed at the top of the 'interest real estate' list 403, The controller 180 receives a long press touch input that presses one point of the area in which the list 403 is displayed for a preset time, Lt; / RTI >

Then, in a state in which the long press touch input is maintained, the touch input (e.g., sliding, swiping, or the like) pushing in a predetermined direction The controller 180 displays a list of 'favorite roads' 401 and 'interest real estate' displayed on the flexible display unit 251 as shown in FIG. 11 (c) The position of the list 403 can be switched. In FIG. 11, only the switching of the two favorite lists to the upper and lower positions has been described, but it will be readily apparent to those skilled in the art that it is also possible to switch between the left and right positions through the same method.

12 is a diagram for explaining an example of adjusting the size of the favorite list displayed on the flexible display unit 251 based on the touch input.

When the control unit 180 receives a touch input of a predefined pattern with respect to the flexible display unit 251 showing a list of favorites of at least one application program, the control unit 180 increases or decreases the size of the favorite list corresponding to the touch input .

For example, as shown in FIG. 12 (a), a 'favorite way' list 401 and an 'interesting real estate' list 403 are displayed together, The controller 180 enlarges the display area of the 'favorite way' list 401 as shown in (c) of FIG. 12 when receiving a multi-touch input that is distant from one point of the area where the display unit 401 is displayed can do. As the display area of the 'favorite way' list 401 is enlarged, the display area of the 'interest real estate' list 403 can be reduced.

For example, as shown in (d) of FIG. 12, when the 'favorite way' list 401 and the 'interest real estate' list 403 are displayed together as shown in FIG. 12 (a) When the controller 180 receives a multi-touch input approaching one point of the area where the list 401 is displayed, the controller 180 displays the display area of the 'favorite way' list 401 as shown in (e) Can be reduced. As the display area of the 'favorite way' list 401 is reduced, the display area of the 'interest real estate' list 403 can be enlarged.

13 is a diagram referred to in explaining an operation of releasing an application program previously allocated to a predetermined area of the flexible display unit 251 by sensing a predefined bending event. At this time, it is assumed that the operation screen is a home screen screen.

If a predefined bending event occurs when the home screen screen is displayed, the control unit 180 can release all the application programs allocated to the respective areas of the flexible display unit 251.

Specifically, while a home screen screen is displayed as shown in FIG. 13A, a predefined area (e.g., a longitudinal axis center area) of the flexible display unit 251 is moved in a predefined direction The controller 180 can release all the application programs that were allocated for each area when a bending event whose number of bending times (e.g., inside) is a predetermined number of times is detected. At this time, as shown in FIG. 13C, the controller 180 may display a message window 421 indicating that the application program has been released for a predetermined time.

(See FIG. 9) to guide the information of the application program after the release of the application program which has been allocated to each area is completed, as shown in (d) of FIG. 13, (E.g., icon, application program name, etc.) associated with the application program that was previously assigned to the application programs 392, 393, 394 may no longer be displayed.

At this time, the control unit 180 may further delete the application programs previously allocated to the respective areas 391, 392, 393, and 394 from the memory 170. Thus, when the memory 170 is insufficient, the user can delete the application programs allocated to the respective areas at once by the operation of generating the predetermined warping event only once without repeating the continuous operation to delete each application program So that the storage space of the memory 170 can be ensured, thereby enhancing user convenience.

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.
