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

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

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

On the other hand, for convenience of explanation, an action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching an object on a screen is called a "contact touch." The position at which the object is in close proximity touch on the touch screen means a position where the object is perpendicular to the touch screen when the object is in close proximity touch.

The touch sensor may be configured to detect a position, an area, a pressure at the touch, a capacitance at the touch, and the like, when the touch object applying the touch on the touch screen is touched on the touch sensor. Here, the touch object is an object applying a touch to the touch sensor and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

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

Meanwhile, the controller 180 may perform different control or perform the same control according to the type of touch object that touches the touch screen (or a touch key provided in addition to the touch screen).

On the other hand, the controller 180 can calculate the position of the wave generation source through the information detected from the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time when the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generation source may be calculated using a time difference from the time when the ultrasonic wave reaches the light as the reference signal.

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

The camera 121 and the laser sensor may be combined with each other to detect a touch of a sensing object with respect to a 3D stereoscopic image. The photo sensor may be stacked on the display element, which is configured to scan the movement of the sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column and scans contents mounted on the photo sensor by using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of light change, and thus, the position information of the sensing object can be obtained.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

3 is a conceptual diagram illustrating a posture of the flexible display unit according to an exemplary embodiment. 4 is a flowchart representatively showing a control method of the present invention. 5 and 6 are conceptual views illustrating the control method described with reference to FIG. 4.

The present invention may include the flexible display unit 251 described with reference to FIG. 2. In this case, the flexible display unit 251 according to the exemplary embodiment of the present invention may be bent, curled, or folded.

For example, as shown in FIG. 3A, the portion 212 of the flexible display unit may be curled or bent.

A portion of the flexible display unit is adjacent to the first edge portion 212 adjacent to one end (or one side) 210 and the other end (end opposite to the one end) (or other side) 290 of the flexible display unit 210. It may be a second edge portion 292.

In addition, as illustrated in FIG. 3B, the flexible display unit 251 may be folded based on a virtual line 214 adjacent to one end 210 of the flexible display unit. Although not shown, the flexible display unit 251 may be folded based on a virtual line adjacent to the other end 290 positioned on the opposite side to the one end 210.

That is, a portion of the flexible display unit is one region including one end of the flexible display unit as illustrated in (a) of FIG. 3 or adjacent to one end of the flexible display unit as illustrated in (b) of FIG. 3. It may be a region or a virtual line adjacent to one end of the flexible display unit.

Hereinafter, a portion of the flexible display unit is described as an edge portion adjacent to one end (or the other end) of the flexible display unit. The edge portion adjacent to one end (or the other end) may include at least one of one region including one end (or the other end) described above, one region adjacent to one end (or the other end), and a virtual line adjacent to one end of the flexible display unit. .

The bending of at least a part of the flexible display unit described above may be understood as having the same meaning as at least a portion of the flexible display unit is curled or at least a part of the flexible display unit is folded. That is, in the present invention, any expression may be applicable as long as it means that a part of the flexible display unit is changed from a flat state (eg, a first state) to a non-flat state (eg, a second state). Hereinafter, for the convenience of explanation, the description will be mainly focused on the expression 'bent', and the expression 'bent' will be applicable to expressions such as 'curled', 'bent' and 'folded'.

In addition, in the above description, the edge portions adjacent to one end and the other end (eg, the lower and the upper end) positioned in the vertical direction of the flexible display unit have been described. However, the above description has been made on one end and the other end (eg, the horizontal end of the flexible display unit). For example, even if the edge portion adjacent to the left end and the right end is bent, it may be analogously applied.

Meanwhile, the flexible display unit 251 of the present invention may be bent by an external force or by the control of the controller. Here, the external force may mean a force for changing the shape of the flexible display unit 251, for example, a force applied from the user.

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

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

Meanwhile, in the present invention, the flexible display unit 251 may be bent under the control of the controller. In detail, the controller 180 may control a portion of the flexible display unit 251 to bend based on the screen information displayed on the flexible display unit even when no external force is applied. For example, the controller 180 may control an electric signal supplied to a portion of the flexible display unit 251 to bend or unfold a portion of the flexible display unit 251.

In addition, when the screen information displayed on the flexible display unit satisfies a preset condition, the controller 180 may cause a portion of the flexible display unit 251 to bend. The preset condition may be a condition for bending the flexible display unit 251 in a flat state, unfolding in a flat state in a curved state, or changing a degree of bending. For example, the preset condition may be a case where there is unprinted screen information, and a detailed description thereof will be described later.

In addition, it is apparent that the present invention can restore the curved state of the flexible display unit 251 back to a flat state by an external force or by a controller.

The present invention may include the flexible display unit 251 described with reference to FIGS. 2 and 3. At this time, the mobile terminal according to an embodiment of the present invention may proceed to output the screen information to the flexible display unit (S210).

The screen information may be information included in at least one of the electronic document 300, the page 300, and the list 300 that can be output to the flexible display unit 251. For example, the electronic document 300 may include a digital image, a word processing, a spreadsheet, a presentation document, and the like.

The page 300 may include a web page and an application execution screen.

The list 300 includes selectable items and may be named as a table of contents, a list, and the like. The list 300 may include a message list, an email list, and the like.

The screen information may be output based on selection (or touch) of an icon of an application. For example, as shown in (a) of FIG. 5, when an icon of a message related application is selected, the controller 180 can display screen information corresponding to an execution screen of a message related application or a message list. 251).

Subsequently, when the first screen information is output to the flexible display unit 251 and second screen information different from the first screen information is not output, the step of controlling the flexible display unit to bend the portion of the flexible display unit is performed. (S220).

The electronic document 300, the page 300, and the list 300 may have a length and a width. In this case, when at least one of the length and width of the electronic document 300, the page 300, or the list 300 exceeds the output area of the flexible display unit 251, there may be unprinted screen information. That is, when at least one of the length and width of the electronic document 300, page 300, or list 300 exceeds the output area of the flexible display unit 251, the electronic document 300, page 300 ) Or the first screen information 310 of the list 300 may be output, and the second screen information 320 different from the first screen information may not be output.

For example, as illustrated in FIG. 5B, when the size (length) of the list 300 exceeds the output area of the flexible display unit, the flexible display unit 251 may include a first list of the list 300. The screen information 310 may be output, and the second screen information 320 different from the first screen information may not be output.

Hereinafter, for convenience of description, a case where the length of the electronic document 300, the page 300, or the list 300 exceeds the length of the flexible display unit will be described as an example. However, the contents described below may be analogously applied similarly to the case where the width of the electronic document 300, the page 300, or the list 300 exceeds the width of the flexible display unit.

When the first screen information 310 is output to the flexible display unit 251 and the second screen information 320 different from the first screen information is not output, the controller 180 indicates that there is no output screen information. A portion of the flexible display unit may be bent to inform. As described above, a portion of the flexible display unit may be at least one of a first edge portion 212 adjacent to one end 210 of the flexible display unit and a second edge portion 292 adjacent to the other end 290 of the flexible display unit. have.

The bending position of the flexible display unit may be determined based on the position at which the second screen information 290 is not output based on the output first screen information 310. In detail, the flexible position of the flexible display unit may be at least one of the first edge portion 212 and the second edge portion 292.

The curved portion of the first and

second edge portions

212 and 292 may be determined based on the position of the second screen information 320 that is not output based on the first screen information 310 output to the flexible display unit 251. Can be. Specifically, when the second screen information 320 is located at one end of the output first screen information 310, the controller 180 can control the first edge portion adjacent to one end of the flexible display unit to bend. have. In addition, when the second screen information 320 is located at the other end of the output first screen information 310, the controller 180 may control the second edge portion adjacent to the other end of the flexible display unit to bend. .

For example, as shown in FIG. 5B, when the unprinted second screen information 320 is located at the bottom of the outputted first screen information 310, an edge portion adjacent to the bottom of the flexible display unit is shown. Can bend.

Meanwhile, the controller 180 may determine the degree of warpage of the first and

second edge portions

212 and 292 based on the size of the unprinted screen information 320. In detail, the degree of warpage of the first and

second edge portions

212 and 292 may include unoutput second screen information positioned at at least one of one end and the other end of the first screen information 310 output to the flexible display unit. May be determined based on the size of the 320).

For example, referring to FIG. 6, as shown in FIG. 6A, second screen information 320 that is not output among the electronic document 300, the page 300, or the list 300 is output. When positioned at the bottom of the first screen information 310, the edge portion 212 adjacent to the bottom 210 of the flexible display unit 251 may be bent. In addition, as illustrated in FIG. 6A, first screen information 310 in which unprinted second screen information 320 is output among the electronic document 300, the page 300, and the list 300 is output. When not located at the top of the edge portion 292 adjacent to the top 290 of the flexible display unit 251 may be in a flat state.

Then, as shown in (b) to (d) of FIG. 6, as the electronic document 300, the page 300 or the list 300 is moved (scrolled) to the upper side, of the output first screen information At least a part 320 is moved toward the upper end of the flexible display unit. Accordingly, at least some of the first screen information 320 is not output. Here, at least part of the first screen information 320 may be defined as new second screen information that is not output as the output is not output as the flexible display unit leaves the display.

Accordingly, the edge portion 292 adjacent to the upper end of the flexible display unit may be bent. At this time, as the electronic document 300, the page 300, or the list 300 is continuously moved to the upper side, at least some of the output first screen information 310 continues to deviate toward the upper side of the flexible display unit. Accordingly, the size of at least some of the first screen information (new second screen information that is not output) 320 is gradually increased. Correspondingly, the degree of warpage of the edge portion 292 adjacent to the upper end of the flexible display unit becomes larger.

On the contrary, as the electronic document 300, the page 300, or the list 300 is continuously moved to the upper side, the size of the unprinted second screen information 320 located at the bottom of the output first screen information 310 is reduced. Gradually becomes smaller. Correspondingly, the degree of warpage of the edge portion 212 adjacent to the bottom of the flexible display unit becomes smaller (ie, unfolded).

Flexible display when the electronic document 300, the page 300, or the list 300 is moved to the lower side while the unprinted second screen information 320 is located at the top of the output first screen information 310. The degree of bending of the part 251 may proceed in the order of (d) to (a) of FIG.

A degree of bending of a portion of the flexible display unit based on the size of the second screen information 320 that is not output may be determined according to a user setting.

As described above, the present invention bends a portion of the flexible display unit so that it is possible to identify that there is unprinted screen information, and thus, whether or not there is unprinted screen information, a position of unprinted screen information, and an unprinted screen information to the user. You can intuitively recognize the size of the information.

Hereinafter, a method of controlling the screen information output to the flexible display unit by using the bending characteristic of the flexible display unit will be described in more detail with reference to the accompanying drawings.

The controller 180 may perform various functions based on the bending or unfolding of a portion of the flexible display unit 251. For example, one of the various functions may be a function of scrolling at least one of the electronic document 300, the page 300, and the list 300. The ability to scroll at least one of the electronic document 300, the page 300, and the list 300 may be understood to move at least one of the electronic document 300, the page 300, and the list 300. have.

In detail, when it is detected that the curved portion of the flexible display unit 251 is unfolded, the controller 180 at least one of the electronic document 300, the page 300, and the list 300 displayed on the flexible display unit 251. Can be moved. That is, the controller 180 may scroll the first screen information 310 displayed on the flexible display unit 251 when it is detected that the curved portion of the flexible display unit 251 is unfolded.

On the contrary, the controller 180 may move at least one of the electronic document 300, the page 300, and the list 300 based on the bending of a part of the flexible display unit 251. In detail, the controller 180 may scroll the first screen information output to the flexible display unit 251 based on the bending of a portion of the flexible display unit 251.

The controller 180 outputs the first output to the flexible display unit 251 based on the first edge portion being unfolded while the first edge portion 212 adjacent to one end of the flexible display unit 251 is bent. 1 Scrolls the screen information to the other end.

On the contrary, the controller 180 outputs the flexible display unit 251 to the flexible display unit 251 based on the unfolding of the second edge portion 292 adjacent to the other end of the flexible display unit 251. The first screen information can be scrolled to one end.

For example, as shown in FIG. 7A, when the web page 300 is output to the flexible display unit 251, a part of the web page 300 is output and the remaining part that is not output is output. When located at the bottom of the portion, the first edge portion 212 adjacent to the bottom 210 of the flexible display unit 251 may be bent. That is, when the first screen information 310 is output to the flexible display unit 251, and the second screen information 320 which is different from the first screen information is located at the bottom of the first screen information 310. The first edge portion 212 adjacent to the bottom 210 of the flexible display unit 251 may be bent.

Meanwhile, when the second screen information 320 that is not output does not exist at the top of the output first screen information 310, the second edge portion 292 adjacent to the top 290 of the flexible display unit 251 may be formed. It may be in a flat state.

In this case, when it is detected that the first edge portion 212 is unfolded by an external force, the controller 180 may move the web page 300 output to the flexible display unit 251. In detail, the controller 180 may scroll the first screen information 310 output to the flexible display unit 251 when the first edge portion 212 is unfolded by an external force. At this time, the controller 180 is based on the unfolding of the first edge portion 212 adjacent to the lower end 210 of the flexible display unit 251, the web page 300 (first screen information 310) Can be moved to the top.

When the first edge portion 212 adjacent to the bottom portion is flattened by an external force in a curved state, the remaining unprinted portion of the web page may not exist at the bottom portion of the output portion. Specifically, when the first edge portion 212 adjacent to the lower end is flattened by an external force in a bent state, at least some of the unprinted second screen information 320 is output to the flexible display unit 251. . Accordingly, the second screen information 320 that is not output may not exist at the bottom of the flexible display unit 251.

On the other hand, the remaining portion may be located at the upper portion of the output portion as the web page is moved to the upper side. In detail, when the output first screen information 310 is scrolled to the upper side, at least some of the output first screen information 310 is displaced toward the upper end of the flexible display unit 251, and accordingly, the first At least some of the first screen information 310 is not output. Here, at least a portion of the first screen information 310 that is not outputted according to scrolling may be understood as new second screen information that is not outputted.

In this case, as illustrated in (b) of FIG. 7A, the controller 180 may control the flexible display unit such that the second edge portion 292 adjacent to the upper end 290 of the flexible display unit 251 is bent. have.

Similarly, when the second edge portion 292 adjacent to the upper end is unfolded by an external force, the web page 300 may move to the lower side. Accordingly, the second unprinted second screen information 320 of the web page may be located at the bottom of the outputted first screen information 310. Accordingly, as shown in (c) of FIG. 7A, when the second edge portion 292 adjacent to the upper end is unfolded in a flat state, the lower edge 210 of the flexible display unit 251 The first edge portion 212 can be curved.

In summary, if it is detected that the edge portion adjacent to one end of the flexible display unit 251 is bent, the controller 180 outputs the electronic document 300, the page 300, and the output to the flexible display unit 251. At least one of the lists 300 may be moved to the other end opposite to the one end. In other words, when it is detected that the edge portion adjacent to one end of the flexible display unit 251 is bent, the controller 180 displays the first screen information 310 output to the flexible display unit 251 at the one end. You can scroll to the opposite end.

More specifically, a method of moving at least one of the electronic document 300, the page 300, and the list 300 as the curved portion of the flexible display unit 251 is unfolded will be described with reference to the accompanying drawings.

As shown in (a) of FIG. 7B, when the portion 310 of the list 300 is output to the flexible display unit 251 and the remaining portion 320a other than the portion is not output, the controller 180 The portion 212 of the flexible display unit 251 may be bent. When the first screen information 310 is output to the flexible display unit 251 and the second screen information 320a different from the first screen information 310 is not output, the controller 180 is the flexible display unit 251. Portion 212 may be bent.

The controller 180 is located at the bottom of the first screen information 310 that is not output second screen information 320a, and the first edge portion 212 adjacent to the bottom of the flexible display unit 251. This can be bent.

Then, as shown in (a) and (b) of FIG. 7B, when it is detected that the first edge portion 212 adjacent to the lower end is bent, the list 300 may be moved upward. . That is, when it is detected that the first edge portion 212 adjacent to the bottom is bent in a bent state, the first screen information 310 output to the flexible display unit 251 may scroll to the upper side.

As the list 300 is moved toward the top, the remaining

portions

320a and 320b of the list 300 may be positioned at the top and the bottom of the output portion 310. In detail, when the first screen information 310 output to the flexible display unit 251 scrolls upward, at least a portion of the second screen information 320a which is not output is output to the flexible display unit 251. In addition, at least a part of the output first screen information 310 is moved toward the upper end of the flexible display unit 251, and thus at least a part of the first screen information 310 is not outputted. That is, new second screen information 320b that is not output is present at the upper end of the screen information 310 output to the flexible display unit 251.

As illustrated in (b) of FIG. 7B, when it is detected that the first edge portion 212 is continuously extended, the controller 180 can continuously move the list 300 to the top based on the detection. Accordingly, the size of the remaining portion 320b located at the top of the output portion 310 becomes larger and larger, and the size of the remaining portion 320a positioned at the bottom thereof becomes smaller. That is, the size of the unprinted new second screen information 320b located at the top of the output screen information 310 is gradually increased, and the size of the unprinted second screen information 320a located at the bottom thereof is gradually smaller. You lose.

The controller 180 may control the first edge part 212 based on the size of the remaining

unprinted parts

320a and 320b (unprinted second screen information 320a and new unprinted second screen information 320b). And the degree of warpage of the second edge portion 292.

Subsequently, as shown in (c) of FIG. 7B, when the first edge portion 212 adjacent to the bottom of the flexible display unit 251 is completely unfolded, the bottom edge of the list may be output. That is, outputting the bottom edge of the list may mean that the remaining unprinted portion of the list does not exist at the bottom of the output portion. That is, it may mean that there is no second screen information 320 that is not output at the bottom of the first screen information 310 output to the flexible display unit 251.

Although not shown, if it is detected that the second edge portion 292 adjacent to the upper end of the flexible display unit 251 is bent, the list 300 may be moved to the lower side.

In addition, although not shown, if it is detected that the edge portion adjacent to one end of the flexible display unit 251 is bent in a flat state, the controller 180 based on the detection, the electronic document 300, the page 300, and the list 300. You can also move at least one of

The controller 180 may move at least one of the electronic document 300, the page 300, and the list 300 based on a preset touch applied to the flexible display unit 251. For example, the preset type of touch may include a drag touch or a swipe touch. That is, at least one of the electronic document 300, the page 300, and the list 300 output to the flexible display unit 251 may be moved based on a preset touch applied to the flexible display unit 251. have.

That is, when a touch of a preset method is applied to the flexible display unit 251, the controller 180 may scroll the first screen information 310 output to the flexible display unit 251.

For example, as illustrated in (a) of FIG. 7C, when the web page 300 is output to the flexible display unit 251, a part (first screen information) of the web page 300 is output. When the remaining non-output portion (second screen information) is located at the bottom of the portion, the first edge portion 212 adjacent to the bottom 210 of the flexible display unit 251 may be bent. On the other hand, when the remaining unprinted portion (second screen information) of the web page does not exist at the top of the output portion (first screen information), the second edge portion adjacent to the top 290 of the flexible display unit 251 292 may be flat.

In this case, when a touch of a preset type is detected by the flexible display unit 151, the controller 180 may move a web page (first screen information) output to the flexible display unit 251. For example, the controller 180 may move the web page (first screen information) in the upper direction based on the drag touch applied in the upper direction.

When the web page is moved to the upper side based on a preset touch, the remaining unprinted portion of the web page may not exist at the bottom of the output portion. On the other hand, the remaining portion may be located at the top of the output portion as the web page is moved to the upper side.

In detail, at least some of the unprinted second screen information 320 is output to the flexible display unit 251 as the output first screen information 310 scrolls upward. Accordingly, the second screen information 320 that is not output may not exist at the bottom of the flexible display unit 251.

On the other hand, the remaining portion may be located at the upper portion of the output portion as the web page is moved to the upper side. In detail, when the output first screen information 310 is scrolled to the upper side, at least some of the output first screen information 310 is displaced toward the upper end of the flexible display unit 251, and accordingly, the first At least some of the first screen information 310 is not output. Here, at least a part of the first screen information 310 that is not outputted according to scrolling may be understood as new second screen information that is not output. In this case, as shown in (b) of FIG. 7C, the controller ( 180 may control the flexible display unit such that the second edge portion 292 adjacent to the upper end 290 of the flexible display unit 251 is bent.

Similarly, as shown in FIG. 7C, when the drag touch applied to the flexible display unit 251 in the lower direction is applied, the web page 300 may move to the lower side. Accordingly, the unprinted portion (non-printed new second screen information) of the web page may be located at the bottom of the output portion (outputted screen information). As shown in (c) of FIG. 7C, as the web page 300 is moved to the lower side, a portion (output screen information) of the remaining unprinted portion of the web page (new output screen information) is output. When located at the bottom, the first edge portion 212 adjacent to the bottom 210 of the flexible display unit 251 may be bent.

A process of moving an electronic document based on a preset touch applied to the flexible display unit is illustrated in FIG. 7D.

As shown in (a) of FIG. 7D, a portion 310 of the list 300 (first screen information 310 is output to the flexible display unit 251 and the remaining portion 320a different from the portion) ( When the second screen information is not output, the controller 180 may cause a part 212 of the flexible display unit 251 to be bent. The first edge portion 212 adjacent to the lower end of the flexible display unit 251 may be bent based on the position of the lower portion 310 (first screen information) output from the screen information.

Thereafter, as shown in FIGS. 7D and 7B, when a drag touch is applied to the flexible display unit 251 in the upper direction, the list 300 may be moved upward. That is, when a drag touch is applied to the flexible display unit 251 in the upper direction, the first screen information 310 output to the flexible display unit 251 may scroll to the upper side.

As the list 300 is moved toward the top, the remaining

portions

320a and 320b of the list 300 may be positioned at the top and the bottom of the output portion 310.

In detail, when the first screen information 310 output to the flexible display unit 251 scrolls upward, at least a portion of the second screen information 320a which is not output is output to the flexible display unit 251. In addition, at least a part of the output first screen information 310 is moved toward the upper end of the flexible display unit 251, and thus at least a part of the first screen information 310 is not outputted. That is, new second screen information 320b that is not output is present at the upper end of the screen information 310 output to the flexible display unit 251.

As illustrated in (b) of FIG. 7D, when a drag touch is applied to the flexible display unit 251 to the upper side, the controller 180 may move the list 300 to the upper side based on the detection. Accordingly, the size of the remaining portion 320b located at the top of the output portion 310 becomes larger and larger, and the size of the remaining portion 320a positioned at the bottom thereof becomes smaller. That is, the size of the unprinted new second screen information 320b located at the top of the output screen information 310 is gradually increased, and the size of the unprinted second screen information 320a located at the bottom thereof is gradually smaller. You lose.

The controller 180 may determine the first edge portion 212 based on the size of the remaining

portions

320a and 320b (not outputted second screen information 320a and new outputted second screen information 320b). ) And the degree of warpage of the second edge portion 292 can be changed.

Subsequently, as shown in (c) of FIG. 7D, when the bottom edge of the list is output based on the drag touch applied to the flexible display unit 251 in the upper direction, adjacent to the lower end of the flexible display unit 251. The first edge portion 212 can be fully straightened. That is, outputting the bottom edge of the list may mean that the remaining unprinted portion of the list does not exist at the bottom of the output portion. That is, it may mean that there is no second screen information 320 that is not output at the bottom of the first screen information 310 output to the flexible display unit 251.

As described above, the present invention may provide a method of controlling screen information output from the flexible display unit according to the bending characteristics of the flexible display unit. In addition, according to the present invention, a portion of the flexible display unit may be bent so that an unprinted portion of at least one of the electronic document, the page and the list can be identified according to the movement of at least one of the electronic document, the page and the list. Through this, the user can more easily use the flexible display unit with improved usability.

Hereinafter, a method of bending a portion of the flexible display unit such that a portion not read by the user among the at least one unprinted portion of the electronic document, the page, and the list can be bent will be described in detail with reference to the accompanying drawings.

8, 9A, 9B, 9C, and 9D are conceptual views illustrating a method of controlling the flexible display unit to identify screen information that is not read by a user among unprinted screen information.

As described above, when only a portion of the electronic document output to the flexible display unit 251 is output and the remaining portion is not output, the controller 180 bends a portion of the flexible display unit based on the relative position of the portion and the remaining portion. I can lose it. In detail, when the first screen information is output to the flexible display unit 251 and second screen information different from the first screen information is not output, the controller 180 displays the non-output based on the first screen information. A portion of the flexible display unit may be bent based on the position where the second screen information is disposed.

On the other hand, when only a part of the electronic document, the page and the list are output and the remaining part is not output, the controller 180 may bend the part of the flexible display unit when the remaining part satisfies a preset condition. In detail, a portion of the flexible display unit may be controlled to bend when the remaining portion that is not output satisfies a preset condition. In other words, when the first screen information is output and second screen information different from the first screen information is not output, the controller 180 displays the flexible screen when the non-output second screen information satisfies a preset condition. A portion of the portion 251 may be bent.

The preset condition may be a condition that determines that at least one unprinted remaining portion of the electronic document, the page, and the list is not read by the user. That is, the unprinted remaining part that satisfies the preset condition may mean a part which is not read by the user or a part that is determined to be unread.

In other words, the preset condition may be a condition in which it is determined that the second screen information that has not been output is not read by the user.

For example, when the remaining part (non-output second screen information) corresponds to a preset condition, as shown in FIG. 8A, when the web page is output to the flexible display unit, Only a part (first screen information) may be output, and the remaining part (second screen information) may not be output from the beginning.

As another example, as shown in FIG. 8B, when the email list 300 is output to the flexible display unit 251, unread mail items among the items included in the email list 300 are not output. When included in the remaining part 320c (second screen information 320c), the remaining part 320c (second screen information 320c) may correspond to a preset condition.

As another example, as shown in FIG. 8C, when the notification list 300 is output to the flexible display unit 251, the remaining portion of the notification list that is not output to the flexible display unit (second screen information). ), The controller 180 may determine that the remaining portion 320c (second screen information 320c) corresponds to a preset condition.

Although not shown, if the moving speed (scrolling speed of the output first screen information) of at least one of the electronic document, page and list is faster than a reference speed, the controller 180 may include at least one of the electronic document, page and list. According to one movement, it may be determined that the remaining portion 320c (at least some of the first screen information and new second screen information that has not been output) corresponds to a preset condition. As described above, at least one movement (scrolling of the first screen information) among the electronic document, the page, and the list may be performed by bending a portion of the flexible display unit 251 or by using a preset touch (for example, a drag touch). ) May be performed based on the addition.

In addition, when the curved portion of the flexible display portion is unfolded faster than the reference speed or unfolded within a reference time, the controller 180 may include at least one unprinted remaining portion of an electronic document, a page, and a list that is moved based on the unfolded portion of the flexible display portion. 320c) (at least some of the first screen information and new second screen information that is not output) may correspond to a preset condition.

In addition, the controller 180 may unfold the bent portion of the flexible display unit within at least one reference time from when the electronic document, the page, and the list are output to the flexible display unit 251, or at least one of the electronic document, the page, and the list. When at least one movement of the electronic document, the page, and the list is performed within a reference time from when the output is performed, it may be determined that the remaining unprinted portion 320c of the moved electronic document corresponds to a preset condition. In other words, the controller 180 may extend the curved portion of the flexible display unit within a reference time from when the first screen information is output to the flexible display unit 251 or within a reference time from when the first screen information is output. When the scrolling of the first screen information is performed, at least a part (non-output new second screen information) 320c outside the output area of the flexible display unit 251 of the first screen information corresponds to a preset condition. It can be judged that.

Hereinafter, with reference to the accompanying drawings will be described in more detail.

As illustrated in (a) of FIG. 9A, a web page 300 may be output to the flexible display unit 251. Specifically, when the web page 300 is output to the flexible display unit 251, a portion 310 (first screen information) of the electronic document is output from the beginning, and the remaining portion 320c different from the portion 310 is output. (Second screen information) may not be output. Here, since the remaining portion 320c (second screen information) is not outputted from the beginning when the web page is output, it may correspond to a preset condition.

The controller 180 may cause a portion of the flexible display unit to bend based on the non-output remaining portion 320c (second screen information) satisfying a preset condition. Based on the remaining portion 320c (second screen information) that satisfies the preset condition being located at one end of the output portion 310 (first screen information), the controller 180 displays the flexible display unit 251. The first edge portion 212 adjacent to one end of the can be bent.

Thereafter, as shown in FIG. 9A (a), the controller 180 may detect that the curved first edge portion 212 is unfolded by an external force. The controller 180 may bend the second edge portion 292 adjacent to the other end based on the speed at which the first edge portion 212 is unfolded. In detail, when the first edge portion 212 is unfolded at the first speed, at least one of the electronic document, the page, and the list (the first screen information) may be moved upward toward the first speed. Here, the first speed may be a reference speed or a speed faster than the reference speed.

As at least one of the electronic document, the page, and the list is moved at the first speed, the remaining portion 320c (at least some of the first screen information and the new second screen information that is not output) may satisfy a preset condition. have.

The control unit 180 outputs the remaining portion 320c (at least a portion of the first screen information and new second screen information not output) of the electronic document to the remaining portion 320c (the output screen information). The flexible display unit 251 may be controlled to bend the second edge portion 292 adjacent to the other end of the flexible display unit 251 based on the position of the other end of the flexible display unit 251.

When the first edge portion 212 is unfolded at a second speed slower than the first speed, the controller 180 may maintain the second edge portion 292 as it is. The second speed may be slower than the reference speed.

For example, as illustrated in (a) and (b) of FIG. 9B, when the first edge portion 212 adjacent to one end of the flexible display portion is unfolded at the second speed, the controller 180 may control the first edge. It may be determined that at least one of the unprinted portion 320d (at least part of the first screen information and the second unprinted second screen information) among the electronic document, the page, and the list moved as the portion is unfolded does not satisfy the preset condition. Can be.

In this case, as shown in (b) and (c) of FIG. 9B, the controller 180 may not display the remaining portion (not output) on the upper portion of the output portion 310 (output first screen information) of the electronic document. Even if 320d) (at least some of the first screen information and new second screen information that is not output) exists, the second edge portion 292 adjacent to the upper end of the flexible display unit 251 may be maintained as it is. Maintaining the second edge portion 292 as it is may mean maintaining the state of the second edge portion in a state before an external force (for example, an external force for straightening the first edge portion) is applied. .

Meanwhile, when at least one of the electronic document, the page, and the list (first screen information) is moved faster than the reference speed, the controller 180 moves at least one of the electronic document, the page, and the list (the first screen information). When the non-output portion 320c (at least some of the first screen information and new second screen information that is not output) satisfies a preset condition, a portion of the flexible display unit 251 may be bent.

As illustrated in (a) of FIG. 9C, a web page 300 may be output to the flexible display unit 251. Specifically, when the web page 300 is output to the flexible display unit 251, a portion 310 (first screen information) of the web page is output from the beginning, and the remaining portion 320c different from the portion 310 is displayed. (Second screen information) may not be output. Here, since the remaining portion 320c (second screen information) is not outputted from the beginning when the web page is output, it may correspond to a preset condition.

The controller 180 may cause a portion of the flexible display unit to bend based on the non-output remaining portion 320c (second screen information) satisfying a preset condition. Based on the remaining portion 320c (second screen information) that satisfies the preset condition being located at one end of the output portion (first screen information), the controller 180 may end one end of the flexible display unit 251. The first edge portion 212 adjacent to may bend.

Thereafter, as shown in FIG. 9C (a), the controller 180 controls the web page 300 based on a preset touch (for example, a drag touch) applied to the flexible display unit 251. Can be moved.

The controller 180 may bend the second edge portion 292 adjacent to the other end based on the movement speed (scrolling speed of the first screen information) of the web page 300. Specifically, when the edge portion 212 adjacent to the bottom of the flexible display unit is unfolded at the first speed, the web page may be moved upward toward the first speed. Here, the first speed may be a reference speed or a speed faster than the reference speed.

Based on the movement of the web page at the first speed, the remaining portion 320c (at least a portion of the first screen information and the second unprinted new screen information) that is not output may satisfy a preset condition.

The controller 180 outputs the remaining portion 320c (at least a portion of the first screen information and the second unprinted new screen information) on which the preset condition is satisfied. The flexible display unit 251 may be controlled to bend the second edge portion 292 adjacent to the other end of the flexible display unit 251 based on the position of the other end of the flexible display unit 251.

Meanwhile, when the electronic document 300 is moved at a second speed slower than the first speed, the controller 180 may maintain the second edge portion 292 as it is. The second speed may be slower than the reference speed.

For example, as shown in (a) and (b) of FIG. 9D, when the web page 300 output to the flexible display unit moves at the second speed, the controller 180 moves the web page. According to the non-output portion 320d (at least a portion of the first screen information, new second screen information that is not output) it can be determined that does not satisfy the preset condition.

In this case, as shown in (b) and (c) of FIG. 9D, the controller 180 may not output the remaining portion 320d at the top of the output portion 310 (output screen information) of the web page. Even if there is (at least a part of the first screen information, new second screen information that is not output), the second edge portion 292 adjacent to the upper end of the flexible display unit 251 may be maintained as it is. Maintaining the second edge portion 292 may mean maintaining the state of the second edge portion before the touch of the preset method is applied.

The controller 180 may determine the degree of bending of the portion of the flexible display unit based on the size of the remaining non-output portion (unprinted screen information) that satisfies the preset condition. Accordingly, the user can determine the amount or size of the unprinted screen information (unread portion (screen information)) that satisfies the preset condition through the degree of bending.

As described above, the present invention can bend a portion of the flexible display unit so that it is possible to identify that there is screen information that is not read by the user among the unprinted screen information of the electronic document, the page, and the list. Through this, the user can intuitively grasp whether there is the screen information that he / she has not read, the amount of the screen information that has not been read, and the location of the unread screen information.

Hereinafter, a method of controlling the posture of the flexible display unit as the size of at least one of an electronic document, a page, and a list is changed will be described with reference to the accompanying drawings.

At least one of the electronic document, the page, and the list 300 may be changed in size based on a touch applied to the flexible display unit 151. In detail, sizes of the first screen information and the second screen information that are not output to the flexible display unit 251 may be changed based on a touch applied to the flexible display unit 151.

For example, as illustrated in FIG. 10A, the flexible display unit 251 may output an e-mail list 300 indicating an unread mail item. At this time, the edge portion 212a adjacent to one end of the flexible display unit 251 may be bent based on the presence of the unprinted screen information 320a of the e-mail list at one end of the outputted first screen information 310. Can be.

At this time, as shown in (a) and (b) of FIG. 10, when any one of the email items included in the email list is touched, an email body corresponding to the touched email item may be output. Subsequently, if the email list is output again based on a user request, the touched email item may be converted into a read state. The touched email item disappears from the email list based on the transition to the read state.

Meanwhile, the email item may be deleted from the email list without changing the screen information based on the user request.

When the touched email item disappears, the size of the email list is reduced. Accordingly, the size of the unprinted portion (second screen information) of the e-mail list is also reduced from 320a to 320b.

That is, when at least one of the items of the list included in the first screen information output to the flexible display unit 251 is deleted (when the size of the first screen information is changed), at least some of the unprinted second screen information is flexible. It is output to the display unit 251. Accordingly, the size of the second screen information that is not output becomes small.

The controller 180 can reduce the degree of warpage of the edge portion 212a based on the size of the unprinted portion (second screen information) being reduced.

As another example, as shown in FIG. 11A, the notification list 300 may be output to the flexible display unit 251. At this time, the edge portion 212a adjacent to one end of the flexible display unit 251 is bent based on the presence of the undisplayed screen information 320a in the one end of the outputted first screen information 310 in the notification list. Can be.

At this time, as shown in (a) and (b) of FIG. 11, when a touch of a preset method (for example, a drag touch or a swipe touch) is applied to any one of the items included in the notification list. One item to which the touch is applied may be deleted. Accordingly, the size of the notification list may be reduced. Accordingly, the size of the unprinted portion of the notification list may also be reduced from 320a to 320c.

The controller 180 may differently control the degree to which the flexible display unit is bent based on the output of at least some of the second screen information to the flexible display unit. That is, the output of at least some of the second screen information to the display means that the size of the screen information not output to the flexible display is reduced.

The controller 180 may reduce the bending degree of the edge portion 212 in the order of 212a to 212c based on the size of the unprinted screen information being reduced.

In the above description, the degree of warpage of the portion of the flexible display unit is reduced based on the size of the unprinted screen information. However, as described above with reference to FIGS. 8 to 9D, the non-displayed screen information is preset. The same / similarity may apply even when the condition is satisfied.

12A, 12B, 13A, 13B, 14A, 14B, and 14C are conceptual views illustrating various embodiments of controlling screen information by using a bending characteristic of an electronic document.

The controller 180 may reduce (zoom out) the size of at least one of the electronic document, the page, and the list based on the bending of the flexible display unit. In detail, the controller 180 may change the size of the first screen information and the second screen information that are not output to the flexible display unit 251 based on the curved portion of the flexible display unit being unfolded.

For example, as shown in (a) of FIG. 12A, the unprinted remaining portion 320 (second screen information) of the list is positioned at one end and the other end of the outputted portion 310 (first screen information). In this case, the controller 180 may control the flexible display unit 251 to bend the first edge portion 212 adjacent to one end of the flexible display unit 251 and the second edge portion 292 adjacent to the other end of the flexible display unit 251. have.

In a state where the first and

second edge portions

212 and 292 are bent, the controller 180 may control the first and

second edge portions

212 and 292 as illustrated in FIG. 12A. At the same time it can detect the spreading.

If it is detected that the first and

second edge portions

212 and 292 are unfolded at the same time, the controller 180 can determine at least one of the electronic document, the page, and the list 300 output from the flexible display unit 251. Can be reduced in size Specifically, when it is detected that the first and

second edge portions

212 and 292 are unfolded at the same time, the controller 180 may not output the first screen information and the first screen information that are located at one end and the other end of the first screen information. The size of the second screen information may be reduced.

The size of the remaining portion 320 (second screen information) that is not output to the flexible display unit 251 may be reduced based on the unfolding of the first and

second edge portions

212 and 292. Thereafter, when the first and

second edge portions

212 and 292 are in a flat state, as shown in FIG. 12A (c), the flexible display unit 251 includes an entire electronic document, an entire page, and an entire list. At least one may be output. In detail, when the first and

second edge portions

212 and 292 are bent in the flat state, the flexible display unit 251 may output at least some of the unprinted second screen information.

Reducing the size of at least one of the electronic document, page, and list may mean reducing at least one of a length and a width exceeding an output area of the flexible display unit 251. The screen information included in at least one of the electronic document, the page, and the list 300 may be reduced in proportion to the reduction of at least one of the length and width.

On the other hand, as shown in (a) of FIG. 12B, when the first edge portion 212 adjacent to one end and the second edge portion 292 adjacent to the other end are flat, the flexible display unit 251 At least one of the entire electronic document, the entire page, and the entire list may be output. That is, when the first and

second edge portions

212 and 292 are bent in a flat state, the undisplayed second screen information may be output to the flexible display unit 251. Then, as shown in (a) to (c) of FIG. 12B, if the first and second edge portions are detected to be bent at the same time, the electronic document, page, and list of the electronic document, page and list output to the flexible display unit 251 are detected. At least one size can be enlarged.

Enlarging the size of at least one of the electronic document, the page and the list is such that enlarging at least one of the length and width of at least one of the electronic document, the page and the list exceeds the output area of the flexible display unit 251. Can mean. Any one of the length and width that is enlarged may be determined based on a position at which the flexible display unit 251 is bent.

For example, when the first edge portion adjacent to one end and the second edge portion adjacent to the other end of the flexible display unit are bent, the length and the width of the at least one of the electronic document, the page, and the list exceed the one end and the other end. At least one can be enlarged. Screen information included in at least one 300 of an electronic document, a page, and a list may be enlarged in proportion to an enlargement of at least one of the length and width.

Meanwhile, if it is detected that a portion of the flexible display unit 251 is further bent, the controller 180 can move at least one 300 of electronic documents, pages, and lists outputted to the flexible display unit 251. have. In detail, when it is detected that a portion of the flexible display unit 251 is further bent, the controller 180 may scroll first screen information output to the flexible display unit 251.

For example, as illustrated in FIG. 13A, when it is detected that the first edge portion is further bent while the first edge adjacent to one end of the flexible display unit 251 is bent, the electronic document, the page, and the list may be selected. At least one 300 may be moved in the other end direction. That is, the first screen information output to the flexible display unit 251 may be scrolled to the other end based on the first edge portion being further bent in a state where the first edge adjacent to one end of the flexible display unit 251 is bent. Can be.

Here, the movement of at least one of the electronic document, the page, and the list 300, which is performed based on the first edge portion being further curved, may include automatic scrolling, movement based on an image included in the page, and text included in the page. It may include various movements such as movement based on a paragraph, movement based on consonants or alphabets in a contact list, movement based on a date in the case of an execution screen of a messenger application.

For example, as illustrated in FIG. 13B, when an image is included in the page 300, the controller 180 may further bend in a state where the first edge adjacent to one end of the flexible display unit 251 is bent. Based on the detection, the page may be moved (scrolled) based on the image 342 included in the page 300.

Meanwhile, the controller 180 may perform a preset function based on the bending of the portion of the flexible display unit in the first direction and the bending of the portion of the flexible display unit in the second direction opposite to the first direction.

The bending of the portion in the second direction opposite to the first direction may be performed by an external force or may be performed by the control of the controller.

For example, as illustrated in (a) of FIG. 14A, the message list 300 may be output to the flexible display unit 251. In this case, when there is an unprinted remaining portion 320 (second screen information) of the message list 300, a portion 212 of the flexible display unit 251 may be bent in the first direction.

Thereafter, as shown in (b) of FIG. 14A, the portion 212 may be bent in a second direction opposite to the first direction by an external force.

In this case, as shown in FIG. 14A (c), the controller 180 outputs the screen information 212 output to a portion of the first screen information output to the flexible display unit 251 in the second direction. And unprinted second screen information 320 (items of the message list) 330 extending from the screen information 212 output to the portion.

As another example, as illustrated in (a) of FIG. 14B, the web page 300 may be output to the flexible display unit 251. The web page 300 may include text, an image, an advertisement, etc. In this case, when there is an unprinted remaining portion 320 (second screen information) of the web page 300, the flexible display is present. A portion 212 of the part 251 may be bent in the first direction.

Thereafter, as shown in (a) and (b) of FIG. 14B, the portion 212 may be bent in a second direction opposite to the first direction by an external force.

In this case, the controller 180 may edit the web page output to the flexible display unit 251 based on the portion 214 bent in the second direction. For example, the controller 180 may limit the output of the advertisement included in the web page when the part 212 is bent in the second direction.

In addition, although not shown, the controller 180 may perform different functions based on the position bent in the second direction.

For example, the controller 180 may be configured such that the first edge portion adjacent to one end of the flexible display unit 251 and the second edge portion adjacent to the other end are bent in a first direction, and the first edge portion corresponds to a second direction. If the first edge is bent in the second direction when the second edge portion is bent in the second direction, and the first and second edge portion is bent in the second direction together to perform the third function can do. Any of the first to third functions may be employed as long as the functions can be performed by the mobile terminal.

On the other hand, the controller 180 may control the posture of the flexible display unit 251 based on the screen information output to the flexible display unit 251.

For example, as illustrated in (a) of FIG. 14C, a web page 300 may be output to the flexible display unit 251. In this case, when the remaining portion 320 of the web page 300 is not output, one portion 212 of the flexible display unit 251 may be bent in the first direction.

If the web page 300 includes information (for example, the advertisement 600 or the empty space 700) whose output is limited by the user setting, the controller 180 may not display the restricted information to the user. A portion of the flexible display unit in which the limited information is output may be bent in a second direction.

The curved portion of the flexible display unit 251 of the present invention may be determined based on the position at which the user holds the flexible display unit 251. For example, as illustrated in (a) and (b) of FIG. 15A, the controller 180 may be connected to the point 294 based on the point 294 at which the user grasps the flexible display unit 251. The flexible display unit 251 may be controlled to bend the portion between adjacent ends.

Meanwhile, in the flexible display unit 251 of the present invention, a critical point 292 may be set. The critical point 292 may be a point corresponding to 1 / n in the length of the flexible display unit 251.

Here, when the point 294 at which the user holds the flexible display unit exceeds the threshold 292, the controller 180 bends a portion between the threshold point and one end adjacent to the threshold 292. The flexible display unit 251 may be controlled.

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