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

1 is a block diagram showing a configuration of a flexible display device according to an embodiment of the present invention. The display device 100 of FIG. 1 can be implemented as a portable device such as a mobile phone, a smart phone, a PMP, a PDA, a tablet PC, navigation, and the like, as well as various types of portable devices having a display function, It is possible. 1, the flexible display device 100 includes all or a part of the display unit 110, the sensing unit 120, and the control unit 130. [ Before describing FIG. 1, the detailed structure of the display unit 110 and the bending sensing method therefor will be described in detail.

2 is a view for explaining a basic structure of a display unit constituting a flexible display device according to an embodiment of the present invention. 2, the display unit 110 includes a substrate 111, a driving unit 112, a display panel 113, and a protective layer 114.

The flexible display device refers to a device that can be bent, bent, folded, or curled like a paper while maintaining the display characteristics of a conventional flat panel display device. Therefore, the flexible display device must be fabricated on a flexible substrate.

Specifically, the substrate 111 can be embodied as a plastic substrate (e.g., a polymer film) that can be deformed by external pressure.

The plastic substrate has a structure in which a base film is treated with a barrier coating on both sides. In the case of the base material, it can be realized by various resins such as PI (Polyimide), PC (Polycarbonate), PET (Polyethyleneterephtalate), PES (Polyethersulfone), PEN (Polysilene Epthalate) and FRP (Fiber Reinforced Plastic). And, the barrier coating is performed on the surfaces facing each other in the base material, and an organic film or an inorganic film can be used to maintain flexibility.

The substrate 111 may be formed of a flexible material such as a thin glass or a metal foil in addition to a plastic substrate.

The driving unit 112 functions to drive the display panel 113. Specifically, the driving unit 112 may apply a driving voltage to a plurality of pixels constituting the display panel 113, and may be implemented as an a-si TFT, a low temperature poly silicon (LTPS) TFT, an OTFT (organic TFT) have. The driving unit 112 may be implemented in various forms according to the embodiment of the display panel 113. For example, the display panel 113 may include an organic light emitting element composed of a plurality of pixel cells and an electrode layer covering both sides of the organic light emitting element. In this case, the driving unit 112 may include a plurality of transistors corresponding to the respective pixel cells of the display panel 113. The controller 130 applies an electric signal to the gates of the respective transistors to emit the pixel cells connected to the transistors. Accordingly, an image can be displayed.

Alternatively, the display panel 113 may be implemented as an EL, an electrophoretic display (EPD), an electrochromic display (ECD), a liquid crystal display (LCD), an AMLCD, a plasma display panel (PDP) However, in the case of an LCD, a separate backlight is required because it can not emit light by itself. For LCDs where no backlight is used, ambient light is used. Therefore, in order to use the LCD display panel 113 without a backlight, conditions such as an outdoor environment with a large amount of light must be satisfied.

The protective layer 114 functions to protect the display panel 113. For example, materials such as ZrO 2, CeO 2, and Th 2 O 2 may be used for the protective layer 114. The protective layer 114 may be formed in the form of a transparent film to cover the entire surface of the display panel 113.

2, the display unit 110 may be implemented as an electronic paper. Electronic paper is a kind of display that applies general ink characteristics to paper, and differs from ordinary flat panel displays in that it uses reflected light. On the other hand, the electronic paper can be changed by using a twist ball or electrophoresis using a capsule.

Meanwhile, when the display unit 110 is made of a transparent material, the display unit 110 can be realized as a display device having bending properties and transparency. For example, when the substrate 111 is formed of a polymer material such as plastic having a transparent property, the driving unit 112 is implemented as a transparent transistor, and the display panel 113 is implemented as a transparent organic light emitting layer and a transparent electrode, Lt; / RTI >

Transparent transistor means a transistor fabricated by replacing opaque silicon of a conventional thin film transistor with a transparent material such as transparent zinc oxide, titanium oxide, or the like. As the transparent electrode, a new material such as indium tin oxide (ITO) or graphene may be used. Graphene refers to a substance with a transparent nature that forms a honeycomb-like planar structure of carbon atoms. 3 to 5 illustrate an example of a method of detecting a shape change, that is, a bending in a flexible display device according to an embodiment of the present invention. FIG.

The flexible display device 100 may be bent by external pressure and deformed in shape. Bending may include normal bending, folding, and rolling. Normal bending refers to the state in which the flexible display device is bent, and differs from folding and rolling in that the bent surfaces do not touch each other. have.

Folding refers to a state in which the flexible display device is folded. Folding and general bending can be classified according to the degree of bending. For example, if the bending is performed over a certain radius of curvature, it is defined as a folded state, and if the bending is less than the radius of curvature, it can be defined as general bending.

Rolling means that the flexible display device is being rolled. Rolling can also be judged based on the radius of curvature. For example, a state in which a bend exceeding a predetermined radius of curvature is continuously detected over a certain region is defined as rolling, and a state in which bending having a radius equal to or greater than a certain radius of curvature is detected in a relatively small region can be defined as folding.

However, the definition of the various form variations as described above is merely an example, and may be defined differently depending on the type, size, weight, and characteristics of the flexible display device. For example, if the surfaces of the flexible display device 100 are bendable enough to touch each other, the folding may be defined as a state in which the device surfaces contact each other at the same time as bending. On the other hand, rolling may be defined as a state in which the front surface and the back surface of the flexible display device are in contact with each other due to bending.

For ease of explanation, this specification refers to these various types of bending and other bending types collectively as bending.

The flexible display device 100 can sense bending in various ways.

For example, the sensing unit 120 may include a bend sensor disposed on one surface such as a front surface or a rear surface of the display unit 110, or a bend sensor disposed on both surfaces. The controller 130 may sense the bending by using a value sensed by the bend sensor of the sensing unit 120.

Here, the bend sensor refers to a sensor that can bend itself and has a characteristic that the resistance value varies depending on the degree of bending. The bend sensor may be implemented as a strain gauge. The strain gauge detects the deformation of the surface of the object to be measured according to the change of the resistance value by using a metal or semiconductor whose resistance varies greatly depending on the magnitude of the applied force. In general, a material such as a metal has a characteristic in which the resistance value increases as the length increases according to the external force, and the resistance value decreases as the length decreases. Therefore, it is possible to judge whether or not the bending is performed by detecting the change in the resistance value.

The sensing unit 120 senses the resistance value of the bend sensor using the magnitude of the voltage applied to the bend sensor or the magnitude of the current flowing through the bend sensor, and determines the bending state Can be detected.

3 shows a state in which the bend sensor is embedded in the front surface of the display unit 110. However, this is merely an example, and the bend sensor may be embedded in the back surface of the display unit 110, . In addition, the shape, number, and position of the bend sensor can be variously changed.

FIG. 3 shows an example in which a plurality of bar-shaped bend sensors are arranged in a horizontal direction and a vertical direction to form a lattice shape.

3, the bend sensor includes bend sensors 21-1 through 21-5 arranged in a first direction and bend sensors 22-1 through 22-5 arranged in a second direction perpendicular to the first direction . Each of the bend sensors may be spaced apart from each other by a predetermined distance.

In FIG. 3, five bend sensors 21-1 to 21-5 and 22-1 to 22-5 are arranged in each of the horizontal and vertical directions. However, this is only an example. It goes without saying that the number of bend sensors can be changed. As described above, the bend sensors are disposed in the horizontal and vertical directions to detect bending occurring in the entire area of the flexible display device. Therefore, in the case where the device has a flexible characteristic or needs to detect bending only in a part , The bend sensor may be disposed only at the corresponding portion.

Each of the bend sensors 21-1 to 21-5 and 22-1 to 22-5 can be realized in the form of an electric resistance sensor using an electric resistance or a micro optical fiber sensor using a strain of an optical fiber. Hereinafter, for convenience of explanation, it is assumed that a bend sensor is implemented as an electric resistance sensor.

4, when the central region located at the center of the left and right edges of the flexible display device 100 is bent downward, the tension due to bending is applied to the bend sensors disposed in the transverse direction 21-1 to 21-5). Accordingly, the resistance values of the respective bend sensors 21-1 to 21-5 arranged in the lateral direction are changed. The sensing unit 120 senses a change in the output value output from each of the bend sensors 21-1 to 21-5 and senses the bending in the horizontal direction based on the center of the display surface. 4, the central region is bent in a downward direction (hereinafter, referred to as Z-direction) perpendicular to the display surface. However, in the upward direction perpendicular to the display surface (hereinafter referred to as Z + direction) It is possible to detect based on the change in the output value of the bend sensors 21-1 to 21-5 in the lateral direction.

5, when the shape of the flexible display device 100 is bent so that the central region located at the center thereof is directed upward, the bend sensors 22- 1 to 22-5. The sensing unit 120 may sense shape deformation in the vertical direction based on output values of the vertically arranged bend sensors 22-1 to 22-5. Although FIG. 5 shows the bending in the Z + direction, it is needless to say that bending in the Z-direction can also be detected using the bend sensors 22-1 to 22-5 arranged in the longitudinal direction.

On the other hand, in the case of the diagonal shape deformation, the tensile force is applied to all of the bend sensors disposed in the transverse direction and the longitudinal direction, so that the shape deformation in the diagonal direction is detected based on the output value of the bend sensor arranged in the transverse direction and the longitudinal direction .

Hereinafter, a concrete method of detecting each type of deformation such as general bending, folding, and rolling using a bend sensor will be described.

6 to 8 are views for explaining a method of detecting bending in a flexible display device using a bend sensor in an embodiment of the present invention.

First, FIG. 6 shows a cross-sectional view of the flexible display device 100 when the flexible display device is bent.

When the flexible display device 100 is bent, the bend sensors disposed on one side or both sides of the flexible display device are bent together and have a resistance value corresponding to the applied tension, and output corresponding output values.

For example, when the flexible display device 100 is bent as shown in FIG. 6, the bend sensor 31-1 disposed on the back surface of the flexible display device 100 is also bent, and the resistance value according to the magnitude of the applied tension Output.

In this case, the strength of the tension increases in proportion to the degree of bending. For example, when bending is performed as shown in FIG. 6, the degree of bending of the central region becomes the largest. Therefore, the largest tensile force is applied to the bend sensor 31-1 disposed at the position a3, which is the center area, and thus the bend sensor 31-1 has the largest resistance value. On the other hand, the degree of bending decreases toward the outside. Accordingly, the bend sensor 31-1 has a smaller resistance value toward the points a2 and a1 or a3 and a5 than the point a3 on the basis of a3 point.

If the resistance value output from the bend sensor has the maximum value at a specific point and the resistance value output from the bend sensor decreases toward both directions, the sensing unit 120 determines that the region where the maximum resistance value is detected is the region where bending is performed can do. In addition, the sensing unit 120 may determine that the region where the resistance value is not changed is a flat region where bending is not performed, and that the region where the resistance value is changed by a predetermined amount or more is a bending region where bending is even a little .

7 and 8 are views for explaining a method of defining a bending region in an embodiment of the present invention. In FIGS. 7 and 8, since the flexible display device is bent in the lateral direction with respect to the front surface, the bend sensors disposed in the longitudinal direction are not shown for convenience of explanation. In addition, although the reference numerals for the respective bend sensors are given differently for the sake of convenience, the bend sensors such as the structure shown in Fig. 3 can be used as they are.

The bending area refers to a bent area of the flexible display device. Since the bend sensor is bent together by bending, the bending region can be defined as any point where a bend sensor outputting a resistance value different from that in the original state is disposed.

The sensing unit 120 can sense the size of the bending region, the direction of the bending line, the position of the bending region, the number of bending regions, and the like, based on the relationship between points where the resistance value change is detected.

Specifically, when the distance between the points at which the resistance value change is detected is within the predetermined distance, the points for outputting the resistance value are detected as one bending area. On the other hand, if there is a point where the distance between the points where the resistance value change is detected is separated by a predetermined distance or more, it can be defined by dividing the points into different bending areas based on these points. See FIGS. 7 and 8 for a more detailed description.

7 is a view for explaining a method of detecting one bending area. When the flexible display device 100 is bent as shown in Fig. 7, from the points a1 to a5 of the bend sensor 31-1, from the b1 point to the b5 point of the bend sensor 31-2, the bend sensor 31- 3 from the c1 point to the c5 point and from the d1 point to the d5 point of the bend sensor 31-4, from the e1 point to the e5 point of the bend sensor 31-5.

In this case, the points where the change in the resistance value is sensed by each of the bend sensors 31-1 to 31-5 are located within a predetermined distance from each other and are continuously arranged.

Therefore, the sensing unit 120 can detect the bend from the points c1 to c5 in the bend sensor 31-3 from b1 to b5 in the bend sensor 31-2 from a1 point to a5 point in the bend sensor 31-1, The bend sensor 31-5 detects the area 32 including all the areas from the e1 point to the e5 point as one bending area from the d1 point to the d5 point in the bend sensor 31-4.

8 is a view for explaining a method of detecting a plurality of bending areas.

8, in accordance with the bending of the flexible display device, from a1 point to a2 point and a4 point to a5 point of the bend sensor 31-1, from b1 point to b2 point of the bend sensor 31-2, From d1 to d2 of the bend sensor 31-4, and from d4 to d5, from the c1 to c2 points of the bend sensor 31-3 to c5, The resistance values from the e1 point to the e2 point of the sensor 31-5 and from the e4 point to the e5 point are different from those in the circular state.

From the a1 point to the a2 point and from the a4 point to the a5 point in the bend sensor 31-1, the a3 point is present between the a2 point and the a4 point, but the a2 point to the a4 point are continuous. not. Therefore, when the distance between a2 point and a4 point is spaced by a predetermined distance, the points from a1 point to a2 point and from a4 point to a5 point can be divided into different bending areas. In addition, each point of the other bend sensors 31-2 to 31-5 can be similarly divided.

Therefore, in the bend sensor 31-1, from the points a1 to a2, from the points b1 to b2 in the bend sensor 31-2, from the points c1 to b2 in the bend sensor 31-3 the bend sensor 31-5 defines the area 34 including all the points from the e1 point to the e2 point as one bending area from the d1 point to the d2 point in the bend sensor 31-4 up to the c2 point, From the points b4 to b5 in the bend sensor 31-2 to the point a5 in the bend sensor 31-1 and the bend sensor 31- 4, the area 35 including all the points e4 to e5 in the bend sensor 31-5 from the point d4 to d5 can be defined as another bending area.

On the other hand, the bending region may include a bending line. The bending line may be defined as a line connecting points where the largest resistance value is detected in each bending area.

For example, in the case of FIG. 7, a3 point for outputting the largest resistance value in the bending region 33, a point b3 for outputting the largest resistance value in the bend sensor 31-2, A line 33 connecting a point c3 for outputting the resistance value, a point d3 for outputting the largest resistance value in the bend sensor 31-4, and a point e3 for outputting the largest resistance value in the bend sensor 31-5, Can be defined as a bending line. 7 shows a state in which the bending line is formed in the longitudinal direction in the central area of the display surface.

8, a1 point for outputting the largest resistance value in the bending area 34, b1 point for outputting the largest resistance value in the bend sensor 31-2, A line 36 connecting a point c1 for outputting a large resistance value, a point d1 for outputting the largest resistance value in the bend sensor 31-4, and a point e1 for outputting the largest resistance value in the bend sensor 31-5 ) Can be one bending line. Further, the largest resistance value is output from the bend sensor 31-3 at the point a5 which outputs the largest resistance value in the bending area 35, the point b5 which outputs the largest resistance value by the bend sensor 31-2, The line 36 connecting the points of c5 to d5 outputting the largest resistance value at the bend sensor 31-4 and the point e5 of outputting the largest resistance value at the bend sensor 31-5, It can be a bending line. That is, FIG. 8 shows a state in which two longitudinal bending lines are formed near the left and right edges of the display surface.

9 and 10 are views for explaining an example of a method of detecting a folded state of the flexible display device.

9 is a cross-sectional view of the flexible display device 100 when it is folded.

When the flexible display device is folded, the bend sensors disposed on one side or both sides of the flexible display device are bent together to have a resistance value corresponding to the applied tensile strength.

For example, when the right edge region of the flexible display device 100 is folded toward the center as shown in FIG. 9, the bend sensor 41-1 disposed on the back surface of the flexible display device 100 is bent, The resistance value according to the magnitude of the tension is output.

That is, as in the case of bending, the bend sensor 41-1 has the largest resistance value at the point a3 where the applied tensile strength is the greatest, and has a smaller resistance value toward both directions. That is, the bend sensor 41-1 has a smaller resistance value toward a2, a1, or a4 and a5 than a3, based on the point a3.

Meanwhile, when the flexible display device is folded to bend at a certain radius of curvature or more, the resistance value is sensed at a size larger than a certain size at a point corresponding to the bending line. Accordingly, the controller 130 can determine whether the bending is normal or folded according to the magnitude of the resistance value.

Alternatively, if it is possible to bend the surface of the flexible display device 100 so that the surfaces of the flexible display device 100 and the flexible display device 100 can be brought into contact with each other, the controller 130 may judge whether the folding is performed considering the touch. That is, when the right edge of the flexible display device 100 is bent in the Z + direction and folded to the front side as shown in FIG. 9, the areas spaced apart from each other come into contact with each other on the front surface of the flexible display device 100. In this case, a touch is sensed in one area of the display surface, and the degree of change in the resistance value becomes larger than in the case of ordinary bending. The control unit 130 calculates the distance from the edge of the bend to the bending line and determines that folding is performed when the touch is detected at a position spaced apart by a distance calculated in the opposite direction with respect to the bending line can do. 10 is a diagram for explaining a method of determining a folding area in an embodiment of the present invention. In the case of FIG. 10, since the flexible display device is folded in the horizontal direction with respect to the front surface, bend sensors arranged in the longitudinal direction are not shown for convenience of explanation.

The folding region is a bent region formed as the flexible display device is folded. The folding region is one or more regions including all the points of the bend sensor outputting different resistance values from the original state as the bend sensor is bent as in the case of bending Can be defined. Since the manner of defining and dividing the folding area is the same as that in the bending area, the redundant description will be omitted.

10, the output value of the bend sensor 41-2 varies from b1 to b5 from the points a1 to a5 in the bend sensor 41-1, The bend sensor 41-3 detects a region including all the points from the e1 point to the e5 point from the d1 point to the d5 point in the bend sensor 41-4 from the c1 point to the c5 point in the bend sensor 41-3 42) can be defined as one folding area.

The folding area is divided into two parts based on the folding line. The folding line can be defined as a line connecting points outputting the largest resistance value in each folding area. The folding line can be used with the same meaning as the bending line.

10, a3 point for outputting the largest resistance value in the bend sensor 41-2 in the folding region 42, a point b3 for outputting the largest resistance value in the bend sensor 41-2, A point c3 for outputting the largest resistance value in the bend sensor 41-4, a point d3 for outputting the largest resistance value in the bend sensor 41-4, a point e3 for outputting the largest resistance value in the bend sensor 41-5 The line 43 connecting the first and second electrodes 41 and 42 becomes a folding line.

When folding is detected, the controller 130 may perform an operation different from the operation in the normal bending mode. For example, it is possible to perform operations such as displaying different content screens for each folding area.

Meanwhile, as described above, the flexible display device 100 may be rolled as paper. The control unit 130 can determine whether rolling is performed using the result detected by the sensing unit 120. [

FIGS. 11 to 13 are views for explaining a method of detecting the rolling by the flexible display device.

11 is a cross-sectional view of the flexible display device 100 when it is rolled.

As described above, when the flexible display device 100 is rolled, tension is applied to the bend sensor disposed on one side or both sides of the flexible display device.

In this case, since the intensities of the tensions applied to the bend sensors are close to each other within a certain range, the resistance values output from the bend sensors are also close to each other within a certain range.

For rolling, bending must be more than a certain curvature. Further, when the rolling is performed, the bending area is formed larger than in the case of ordinary bending or folding. When the bending of the bending having a certain radius of curvature or more is continuously detected in the region of a certain size or more, the control unit 130 can determine that the bending is in the rolling state. In the rolling state, the front surface and the back surface of the flexible display device contact each other . 11, when the one side edge of the flexible display device 50 is bent in the Z + direction and rolled inwardly of the display surface, the display surface, that is, the rear surface on which the front surface and the bend sensor 50-1 are disposed, They come into contact with each other.

Therefore, in another example, the control unit 130 may determine whether the front and back surfaces of the flexible display device are in a rolling state, depending on whether they are in contact with each other. In this case, the sensing unit 120 may include a touch sensor. The control unit 130 may include a touch sensor (not shown) disposed on the front and back sides of the flexible display device, It is determined that the flexible display device is rolled.

12 and 13 are views for explaining a method of defining a rolling region in an embodiment of the present invention.

The rolling area means the entire area where the flexible display device is bent to be in a rolling state. The rolling region may also be defined as one or more regions including all points of the bend sensor outputting different resistance values from the original state, such as in the case of normal bending and folding. Since the manner of defining and dividing the rolling region is the same as that in the bending and folding region, redundant description will be omitted.

As shown in FIG. 12, when the flexible display device 50 is rolled as a whole, the entire area 51 of the flexible display device can be defined as a rolling area, and the flexible display device 100 is partially rolled, A portion of the flexible display device 52, 53 may be defined as a different rolling region, as long as the point of outputting a different resistance value from that of the flexible display device is spaced by a predetermined distance.

As described above, the flexible display device 100 can be bent in various forms, and the controller 130 can detect each bending type based on the detection result of the sensing unit 120. [ In addition, the control unit 130 can detect the degree of bending, that is, the bending angle, based on the detection result of the sensing unit 120.

FIGS. 14 and 15 are views for explaining a method of determining the degree of bending.

Referring to FIGS. 14 and 15, the flexible display device 100 determines the extent to which the flexible display device is bent by using a change in the magnitude of the resistance value output at regular intervals in the bend sensor.

Specifically, the controller 130 calculates a difference between a resistance value at a point where the largest resistance value is output from the bend sensor and a resistance value that is output at a point apart from the point by a predetermined distance.

Then, the controller 130 can determine the degree of bending using the calculated resistance value difference. Specifically, the flexible display device 100 may divide the degree of bending into a plurality of levels, and may store and store a resistance value having a predetermined range for each level.

Accordingly, the flexible display device can determine the degree of bending of the flexible display device according to a level belonging to a plurality of levels classified according to the degree of bending of the calculated resistance value difference.

For example, as shown in FIGS. 14 and 15, the resistance value output from the point a5 at which the largest resistance value is outputted from the bend sensor 61 provided on the back surface of the flexible display device 100, The degree of bending can be determined based on the resistance value difference outputted at the point a4.

Specifically, among the plurality of pre-stored levels, the level to which the resistance value difference calculated in the embodiment shown in FIGS. 14 and 15 belongs can be confirmed, and the degree of bending corresponding to the confirmed level can be determined. Here, the degree of bending may be expressed by a bending angle or a bending strength.

15, the degree of bending is larger than that in the embodiment shown in FIG. 14. Therefore, in the embodiment shown in FIG. 15, the resistance value outputted at the bending sensor a5 and the resistance value outputted at the point a4 The difference becomes larger than the difference between the resistance value output at the bending sensor a5 and the resistance value output at the a4 point in the embodiment shown in Fig. Accordingly, when the controller 130 is bent as shown in FIG. 15, it can be determined that the degree of bending is greater.

The controller 130 may perform an appropriate operation according to the degree of bending. For example, when performing a channel zapping operation, if the degree of bending is large, the channel jumping speed can be increased or the channel jumping range can be increased. On the other hand, if the degree of bending is low, channel jumping can be performed on a slower, smaller number of channels. The operation can be performed differently depending on the degree of bending even during operation such as volume adjustment or content switching.

Meanwhile, as described above, the bending direction of the flexible display device 100 may be changed in the Z + direction or the Z-direction.

Bending directions can also be sensed in a variety of ways. For example, the bend sensors may be arranged in two overlapping positions to determine the bending direction according to the difference in the magnitude of the resistance value of each bend sensor. 16 to 18, a method of sensing the bending direction using the overlapping bend sensor will be described.

For convenience of explanation, the case of general bending will be described with reference to Figs. 16 to 18. Fig. Needless to say, folding and rolling can be applied in the same manner as bending.

Referring to FIG. 16, two bend sensors 71 and 72 may be provided on one side of the display unit 110 so as to overlap with each other. In this case, when bending is performed in one direction, the resistance values of the upper bend sensor 71 and the lower bend sensor 72 are detected differently at the point where the bending is performed. Therefore, when the resistance values of the two bend sensors 71 and 72 at the same point are compared, the bending direction can be known.

Specifically, when the flexible display device 100 is bent in the Z + direction as shown in FIG. 17, a tension of a greater strength is applied to the bend sensor 72 below the upper bend sensor 71 at the A point corresponding to the bending line .

On the other hand, when the flexible display device 100 is bent in the backward direction as shown in FIG. 18, the upper bend sensor 71 applies a greater tensile force than the lower bend sensor 72.

Therefore, the control unit 130 can sense the bending direction by comparing the resistance value corresponding to the point A by the two bend sensors 71 and 72. [

16 to 18, the two bend sensors are disposed on one side of the display unit 110 in a superimposed manner, but the bend sensors may be disposed on both sides of the display unit 110. FIG.

19 shows a state in which two bend sensors 71 and 72 are disposed on both sides of the display unit 110. Fig.

Accordingly, when the flexible display device 100 is bent in a first direction perpendicular to the screen (hereinafter referred to as Z + direction), the bend sensor disposed on the first surface of the display unit 110 receives compressive force , The bend sensor disposed on the second surface receives the tension. On the other hand, when bending in a second direction opposite to the first direction (hereinafter referred to as the Z-direction), the bend sensor disposed on the second surface receives compressive force, while the bend sensor disposed on the first surface . In this way, the values sensed by the two bend sensors are detected differently according to the bending direction, and the controller 130 can distinguish the bending direction according to the detection characteristics of the values.

16 to 19, bending directions are sensed by using two bend sensors. However, the bending directions can also be distinguished by a strain gauge disposed on one surface of the display unit 110. FIG. That is, since the strain gauge disposed on one surface is subjected to a compressive force or a tensile force according to the bending direction, the bending direction can be recognized by confirming the characteristics of the output value.

20 shows an example of a configuration in which one bend sensor is disposed on one surface of the display unit 110 to detect bending. Referring to FIG. 20, the bend sensor 71 may be implemented as a closed curve of a circle, a rectangle, or other polygon, and may be disposed at the edge of the display unit 110. The control unit 130 may determine that a point where a change in the output value is detected on the closed curve is a bending area. Also, the bend sensor may be coupled with the display portion 110 in the form of an open curve such as an S-shaped, zigzag ' Z '.

Fig. 21 shows an embodiment in which two bend sensors are arranged so as to intersect with each other. 21, the first bend sensor 71 is disposed on the first side of the display portion 110, and the second bend sensor 72 is disposed on the second side of the display portion 110. [ The first bend sensor 71 is disposed in a first diagonal direction on a first surface of the display portion 110 and the second bend sensor 72 is disposed in a second diagonal direction on a second surface. Accordingly, the first and second bend sensors 71 and 72 may be provided with various bending conditions such as when each edge area is bent, when each edge area is bent, when the center part is bent, when folding or rolling is performed, The output value and the output point are different from each other, and the controller 130 can determine what type of bending has been performed according to the output value characteristic.

In the above-described various embodiments, line-shaped bend sensors are used, but bending can be detected by using a plurality of fragmentary strain gauges.

Figures 22 and 23 show an embodiment for sensing bending using a plurality of strain gauges.

Referring to FIG. 22, a plurality of strain gauges are disposed in the edge region of the display unit 110. The number of strain gauges may vary depending on the size and shape of the display unit 110, predetermined bending detection resolution, and the like.

With the strain gauges arranged as shown in Fig. 22, the user can bend an arbitrary point in an arbitrary direction. Specifically, when one corner region is bent as shown in Fig. 23, a force acts on the strain gage 80-x that overlaps the bending line among the strain gages 80-1 to 80-n arranged in the transverse direction. Accordingly, the output value of the strain gage 80-x becomes larger than the output value of the other strain gauges. Also, among the strain gauges 80-n and 80-n + 1 to 80-m arranged in the longitudinal direction, a force acts on the strain gauge 80-y that overlaps the bending line, and the output value changes. The control unit 130 may determine that the line connecting the two strain gauges 80-x and 80-y whose output values have changed is a bending line.

Alternatively, the flexible display device 100 may sense the bending direction using various sensors such as a gyro sensor, a geomagnetic sensor, an acceleration sensor, or the like, as described with reference to FIGS.

24 and 25 are views for explaining a method of detecting a bending direction using an acceleration sensor as an example of such sensors. According to Figs. 24 and 25, the flexible display device 100 includes a plurality of acceleration sensors 81-1 and 81-2.

The acceleration sensors 81-1 and 81-2 are sensors that can measure the direction of the acceleration and the acceleration when a motion occurs. Specifically, the acceleration sensors 81-1 and 81-2 output a sensing value corresponding to the gravitational acceleration that varies according to the inclination of the apparatus to which the sensor is attached. Therefore, when the acceleration sensors 81-1 and 81-2 are disposed at both edge regions of the flexible display device, the output values sensed by the acceleration sensors 81-1 and 81-2 when the flexible display device is bent . The controller 130 calculates a pitch angle and a role angle using output values sensed by the acceleration sensors 81-1 and 81-2. Accordingly, the bending direction can be determined based on the degree of change of the pitch angle and the roll angle detected by the acceleration sensors 81-1 and 81-2.

24 shows the state in which the acceleration sensors 81-1 and 81-2 are disposed on both side edges of the flexible display device 100 in the transverse direction with respect to the front surface of the flexible display device 100. However, . In this case, when the flexible display device 100 is bent in the vertical direction, the bending direction can be sensed according to the measured values sensed by the angular acceleration sensors 81-3 and 81-4 in the vertical direction.

24 and 25 illustrate a state in which the acceleration sensor is disposed at the left and right edges or the upper and lower edges of the flexible display device 100. However, the acceleration sensor may be disposed at both the upper, lower, left, and right edges, .

As described above, it is also possible to detect the bending direction by using a gyro sensor or a geomagnetic sensor in addition to the acceleration sensor. The gyro sensor is a sensor that detects angular velocity by measuring the force of Coriolis acting in the speed direction when rotational motion occurs. According to the measurement value of the gyro sensor, it is possible to detect in which direction the rotation is performed, so that the bending direction can be detected. The geomagnetic sensor is a sensor that detects the azimuth using a two-axis or three-axis fluxgate. In the case of a geomagnetic sensor, the geomagnetic sensor disposed at each edge of the flexible display device 100 is moved when its edge portion is bent, thereby outputting an electric signal corresponding to the geomagnetism change. The control unit 130 may calculate a yaw angle using a value output from the geomagnetic sensor. Accordingly, it is possible to determine various bending characteristics such as the bending area and the bending direction according to the calculated yaw angle variation.

As described above, the flexible display device 100 can detect bending using various types of sensors. The configuration and sensing method of the sensor described above may be applied to the flexible display device 100 individually or in combination with each other.

Meanwhile, the sensing unit 120 may sense the operation of touching the screen of the display unit 110 by the user in addition to bending.

For example, the sensing unit 120 may include a transparent conductive film such as indium-tin oxide (ITO) deposited on the substrate 111 in the display unit 110 and a film formed on the transparent conductive film. Accordingly, when the user touches the screen, the upper and lower plates of the touched point are brought into contact with each other, and an electric signal is transmitted to the controller 130. The controller 130 recognizes the touch point by using the coordinates of the electrode to which the electric signal is transmitted. Since the touch sensing method is well known in various prior arts, further detailed description is omitted.

When touching, bending, or the like is detected, the control unit 130 determines whether or not a user operation such as touching or bending is intended. Hereinafter, various embodiments of the present invention will be described in detail with reference to the detailed structure of the display unit 110 and the bending sensing method therefor.

# 1: First Embodiment

The display unit 110 displays a screen. Specifically, the display unit 110 may display at least one application icon. Also, the display unit 110 may display an application driving screen. The display unit 110 may also provide a guide to at least one bending gesture for driving an application corresponding to the selected application icon. The display unit 110 may also provide a guide to at least one bending gesture for performing a predetermined function of the driven application. In describing the various embodiments of the present invention, the bending gesture will be defined as a concept including both a folding gesture and a rolling gesture in that folding and rolling are performed only after bending has been performed.

The sensing unit 120 may sense a bending gesture for bending the flexible display device 100. [ Here, the sensing unit 120 may be implemented by various types of bend sensors, and a method of arranging and sensing the bend sensors has been described in detail, and a detailed description thereof will be omitted.

The control unit 130 controls the overall operation of the flexible display device 100. Specifically, the control unit 130 may control all or a part of the display unit 110 and the sensing unit 120.

In particular, the control unit 130 may provide a guide for at least one bending gesture for driving the selected application.

Specifically, the control unit 130 may determine whether the bending of the flexible display device 100 is necessary to drive an application corresponding to the selected application icon.

As a result of the determination, if it is determined that bending of the flexible display device 100 is required, the controller 130 may provide a guide for at least one bending gesture for driving the selected application. For example, in order to drive a gaming application, the flexible display device 100 must be transformed into a square pillar shape. Therefore, the control unit 130 determines that the shape of the flexible display device 100 needs to be a quadrangular prism in order to drive the Jenga game application. Accordingly, the controller 130 may include a guide for making the flexible display device 100 square- .

The bending gesture of the user for bending the flexible display device 100 is sensed through the sensing unit 120 and the bending gesture sensed by the bending gesture is displayed on the display unit 120. [ If judged to be a gesture, the application corresponding to the selected application icon can be driven. For example, if the shape of the flexible display device 100 modified according to the bending gesture of the user is a predetermined shape for driving a gaming application, the control unit 130 can drive the gaming application have.

In addition, the controller 130 detects a plurality of bending gestures of the user for bending the flexible display device through the sensing unit 120, and uses the plurality of bending gestures sensed to transform the flexible display device 100 into a predetermined shape It is possible to drive the application corresponding to the selected application icon. Taking the above-described Zengai game as an example, in the provided guide, the user can repeat the bent and bending gesture. In this case, if the shape of the flexible display device 100 deformed according to the bending gesture of the user is a predetermined shape for driving the gesture game application, the control unit 130 can drive the gesture game application.

If it is determined that bending of the flexible display device 100 is not necessary, the control unit 130 can drive an application corresponding to the selected application icon without providing a guide. For example, the shape of the flexible display device 100 is not necessarily required for driving the SNS application. In this case, the control unit 130 can drive the selected SNS application without providing a separate guide.

The controller 130 may also provide a guide to at least one bending gesture for the driven application to perform a predetermined function.

Specifically, the control unit 130 may determine whether the bending of the flexible display device is necessary in order for the driven application to perform the predetermined function.

As a result of the determination, if it is determined that bending of the flexible display device 100 is required, the controller 130 may provide a guide to at least one bending gesture for performing a predetermined function of the driven application. For example, when the piano application is activated, the display unit 110 can display the piano keyboard as a driving screen. However, one area of the flexible display device 100 needs to be bent in order for the driven piano application to provide a music score screen. In this case, the controller 130 may provide a guide for at least one bending gesture for bending the flexible display device 100.

Also, if the bending gesture of the user for bending the flexible display device is sensed through the sensing unit 120, and the controller 130 determines that the sensed gesture is a preset gesture for the application in which the sensed gesture is driven, As shown in FIG. If the shape of the flexible display device 100 deformed according to the gesture of the user is a predetermined shape for providing the score function in the piano application in which the shape of the flexible display device 100 is driven, Quot;) < / RTI >

The control unit 130 detects a plurality of bending gestures of the user for bending the flexible display device 100 through the sensing unit 120 and displays the bending gestures on the display unit 100 using the plurality of bending gestures sensed. If it is determined that the shape has been changed to the set shape, it is possible to control the driven application to perform the predetermined function. Taking the above-described piano application as an example, in the provided guide, the user can repeat the bent and bending gesture. In this case, if the shape of the flexible display device 100 deformed according to the bending gesture of the user is a predetermined shape for providing the music score function in the piano application in which the shape of the flexible display device 100 is driven, The control unit 130 may perform a different operation according to the number of times the bending has been repeatedly performed such as the number of times of bending sensed through the sensing unit 120, that is, 1, 2, 3, Or perform the same operation. For example, when bending is performed once, page switching is performed. When bending is performed twice continuously, content switching is performed. When bending is performed three times continuously, application switching can be performed. Alternatively, the control unit 130 may perform the same function when the flexible display device 100 deformed by the bending gesture such as 1, 2, 3, etc. has the same shape.

Also, the controller 130 may perform different operations or perform the same operations depending on whether the bending gestures sensed through the sensing unit 120 are a sequential bending gesture or a simultaneous bending gesture. Herein, the sequential bending gesture means that the bending is performed according to the provided first guide, and then the bending is performed according to the provided second guide. The simultaneous bending gesture also means performing bending simultaneously according to the provided first guide and the provided second guide. In this case, the controller 130 performs the first function in the case of the sequential bending gesture, and the second function in the case of the simultaneous bending gesture, even though the shape of the flexible display device 100 deformed by the bending gesture is the same . Alternatively, the control unit 130 may perform the same function when the shape of the flexible display device 100 deformed by the bending gesture is the same, without distinguishing between the sequential bending gesture and the simultaneous bending gesture.

In addition, the controller 130 may provide a guide corresponding to the type of content. For example, when the type of content that is driven is GALLERY or MOVIE, the control unit 130 may provide a guide for the user to view an optimized screen. In this case, the controller 130 may provide a guide using the resolution information of the driven GALLERY or MOVIE. If the type of the content to be played is GAME, the control unit 130 may provide a guide for optimizing the interaction with the user. In this case, the controller 130 can provide a guide by using the type of the driven GAME. For example, when the driven GAME is an airplane game, the control unit 130 can provide a guide for making a roll shape, which is a shape of a flexible display device optimized for an airplane game.

In addition, the controller 130 may provide a guide for deriving a GRIP that is easy for a user to use according to the type of contents.

In addition, the control unit 130 can provide a guide for enabling execution immediately when NOTIFICATION, RSS, and the like come. For example, when a character comes from the other party, the control unit 130 can provide a guide for confirming the character immediately.

In addition, the control unit 130 may provide all or some of the predetermined functions that can be performed in the driven application, together with the guide. Specifically, the control unit 130 can provide some or all of the guides that can be implemented in the driven application, and can display the functions mapped to the respective guides.

When the bending gesture of the user for bending the flexible display device is sensed through the sensing unit 120, the controller 130 compares the sensed bending gesture with the predetermined gesture with respect to the driven application, .

Where the comparison result may be to feedback the accuracy of the detected bending gesture. Feedback on the accuracy of the detected bending gesture may also be feedback on the success of the bending gesture, the failure of the bending gesture, and the completion of the bending gesture. Here, the feedback can be any method that provides the user with the accuracy of the bending gesture, such as haptic feedback, vibration feedback, sound feedback, GUI feedback, such as pop-up windows. For example, if it is determined that the detected bending gesture is not a predefined gesture, the control unit 130 may provide the user with vibration feedback (where the vibration feedback gives vibration feedback only to the area to be bended, Quot ;, or " the bending area is wrong ", or a text-shaped pop-up window). Also, if it is determined that the detected bending gesture is a predetermined gesture, the control unit 130 may provide the user with vibration feedback, a sound 'bending area is correct', or a pop-up window in the form of a text. In this case, the controller 130 may provide a guide for guiding the correct bending gesture again.

Also, if the sensed detected bending gesture is determined to be a predetermined gesture, and corresponding operation is performed, it is possible to indicate that the operation is being performed according to the bending gesture by not displaying the provided guide.

Thus, the user can easily know whether the bending gesture is accurate or not.

The guide also includes a guide for indicating bending / folding lines, a guide for indicating bending / folding directions, a guide for indicating rolling, a guide for haptic feedback, And may be provided in at least one of the related manual guides. In addition, when the flexible display device 100 includes the actuator, the guide may be a guide for guiding the bending operation at a position where the bending should be performed.

Specifically, the guide indicating the bending / folding line can be represented by various lines. For example, a dotted line or a solid line may be used. Also, different lines may be mapped for each bending area or folding area. For example, the bending region may be dotted and the polling region may be mapped to a solid line. The bending / folding lines may also be displayed in different colors or different thicknesses, mapped to bending areas or folding lines, or may be mapped to bending / folding angles or bending / folding directions.

For example, the bending region may be mapped to black and the folding line may be mapped to red. Or a black line may be mapped to a bending / folding line corresponding to a gesture bending / folding in the user direction and a red color may be mapped to a bending / folding line corresponding to a gesture bending / folding in the opposite direction of the user. Or a black line may be mapped to a bending area corresponding to a 60 degree bending gesture and a red line to a bending area corresponding to a 30 degree bending gesture. However, the present invention is not limited thereto and can be mapped in various ways. Or the bending / folding line may be displayed using light. For example, the bending area can be mapped to light that is continuously on (i.e., without blinking) and the folding line can be mapped to on / off repeated light (i.e., blinking light).

Also, the guide indicating the bending / folding direction can be displayed with various symbols such as an arrow or the like. For example, the direction of the arrow can be used to indicate the bending / folding direction.

In addition, guides indicating rolling can be displayed in various symbols. For example, it can be displayed as an arrow, text, line or the like indicating a rolling operation.

In addition, the guide through haptic feedback can be provided in the form of vibration or the like in an area including the bending / folding line.

In addition, manuals related to shape deformation can be provided in text, sound, video, and other manuals. For example, in the case of text, text documentation such as "bend the dotted line 60 degrees inside and bend the solid line 30 degrees outward" can be provided, and sound documentation through sound, bending / folding / rolling It can be provided as a video tutorial explaining the operation.

Here, the guide may indicate an action to be performed together with or after the bending gesture. For example, a guide may be displayed with the number of bends. That is, it is possible to display the number of times that bending should be repeatedly performed in the guide, such as 1, 2, 3, and so on.

The guide also includes FLAP gestures (bending / folding / rolling gestures), HOLD gestures (gestures that maintain and maintain bending / folding / rolling gestures), MOVE gestures (bending / folding / rolling gestures A gesture to move the bending line in a certain direction) should be performed. For example, in the case of a driven e-book application, a FLAP gesture should be performed at the right corner for the next page transition, so that a FLAP gesture must be performed with the guide. In addition, in the case of a Zendai game application, in order to perform a Zenga application, a HOLD gesture for forming a quadrangular prism shape must be performed, so that it is possible to provide a HOLD gesture with a guide. However, the present invention is not limited to the above-described examples, and the user's bending gestures can be mapped differently for different applications. Also, the number of gestures can be mapped differently for different applications.

Further, when the shape of the flexible display device 100 is deformed according to the guide, it is possible to display in which direction the shape should be rotated, whether it should be raised, laid down, or the like after the flexible display device 100 is deformed have.

Wherein the guide is displayed based on a bending region belonging to a predetermined bending range, and the predetermined bending range may be set to include a predetermined error range corresponding to at least one bending gesture. That is, even if the user bends / folds / rolls the flexible display device 100 according to the guide, it is often difficult to bend / fold / roll at an accurate guide position. Therefore, the guide can be set including a predetermined error range, and the bending area can be displayed within a predetermined error range. Also, if the bending / folding / rolling gesture is input within a predetermined error range, the controller 130 may determine that the application is a preset gesture.

When the flexible display device 100 is switched to the standby state and the display unit 110 displays an idle screen including an icon of the application, the control unit 130 displays at least one bending gesture Can be provided. Accordingly, when the bending gesture corresponding to the provided guide is formed, the controller 130 can perform an operation corresponding to the bending gesture. For example, the control unit 130 may provide a guide to at least one bending gesture related to execution of a function of unlocking a flexible display value related to an executable function in the lock screen. Accordingly, if the user performs a bending gesture mapped to each function, the control unit 130 can control the corresponding function to be performed.

The control unit 130 also provides a guide to the bending gesture for unlocking when the flexible display device 100 is switched to the locked state and can perform unlocking when the bending gesture corresponding to the provided guide is established have. For example, the control unit 130 may provide a guide to at least one bending gesture relating to the execution of a lock function of a flexible display device related to an executable function on the idle screen, another idle screen display function, a volume control function, . Accordingly, if the user performs a bending gesture mapped to each function, the control unit 130 can control the corresponding function to be performed.

26 is a block diagram specifically showing the flexible display device according to FIG. 26, the flexible display device 100 includes all or a part of a display unit 110, a sensing unit 120, a controller 130, an actuator unit 140, and a storage unit 150. In the description of FIG. 10, a detailed description of the configuration described previously will be omitted.

The actuator unit 140 operates the bending of the flexible display device 100. Specifically, the flexible display device 100 can be automatically bent or maintained in a bent shape. In addition, the flexible display device 100 can be bent automatically to drive an application or to perform a specific function of a driven application. In addition, when the flexible display device 100 is bent in a shape corresponding to the bending gesture, the bending shape is maintained.

Here, the actuator unit 140 may be embodied as a plurality of polymer series materials or strings arranged in predetermined areas of the flexible display device 100. [

When the actuator unit 140 is a string, in order to manipulate the shape deformation of the flexible display device 100, the control unit 130 changes the tensile force of the string so that the flexible display device 100 is deformed . Accordingly, the flexible display device 100 can be deformed automatically and can maintain a deformed shape.

That is, when a physical force is applied to the flexible display device 100 to deform the shape, the flexible display device 100 receives a backward force to return to the original flat shape. In this case, under the control of the control unit 130, the actuator unit 140 provides a physical force corresponding to the backward force so that the flexible display device 100 maintains the deformed shape.

In particular, the storage unit 150 may map and store a bending gesture for driving an application corresponding to the selected application icon to each application. In addition, the storage unit 150 may store a bending gesture for performing a driven application with a predetermined function in each application.

In the following description of FIG. 48, a detailed description of the configuration will be omitted.

The storage unit 240 stores programs and various data necessary for driving the flexible display device 200. In particular, the storage unit 240 may store information about an application that matches a deformable shape and a deformable shape of the flexible display device.

The control unit 230 controls the overall operation of the flexible display device 200. The control unit 230 may control all or a part of the display unit 210, the sensing unit 220, the actuator unit 240, and the storage unit 250.

Particularly, in a state where the display unit 210 displays the application icon, when the user's gesture for deforming the shape of the flexible display device 200 is sensed through the sensing unit 220, the controller 230 controls the gesture It is determined whether the shape of the corresponding flexible display device 200 is stored in the storage unit 240.

In the case of the stored shape, the controller 230 can detect and drive the application corresponding to the stored shape. For example, the telephone application shown in FIG. 50 will be described as an example. If the user has previously performed the telephone application, the user may remember the shape of the flexible display device 200 for driving the telephone application. In this case, the user can transform the flexible display device 200 into the pre-stored shape while the display unit 210 displays the application icon. Accordingly, the control unit 230 can detect the phone application corresponding to the pre-stored shape from the storage unit 260 and drive the phone application.

When the gesture of the user for shape modification of the flexible display device 200 is sensed through the sensing unit 220 while the display unit 210 displays the application screen on which the display unit 210 is driven, It is determined whether the shape of the flexible display device 200 corresponding to the gesture is a shape stored in the storage unit 240.

In the case of the stored shape, the controller 230 may control to perform a predetermined function of the driven application corresponding to the stored shape. For example, a piano application as shown in FIG. 51 will be described as an example. When the user has previously performed the piano application, the user may memorize the shape of the flexible display device 200 corresponding to the performance of the music score function of the piano application. In this case, the user can change the flexible display device 200 by bending the upper area in the horizontal direction while the display unit 210 displays the piano application driving screen. Accordingly, the control unit 230 can control to directly display the score function corresponding to the deformed shape in the upper region.

The card application shown in FIG. 52 will be described as an example. 52 (a), the user can bend the flexible display device as shown in FIG. 52 (b) while the card application is being executed. In this case, the display unit 110 can divide and display the driven card game application. That is, the control unit 130 may control the display unit 110 to display a private view in one area and a public view in another area.

53 is a flowchart showing a control method of a flexible display device according to the second embodiment of the present invention. Referring to FIG. 53, first, a gesture for deforming the shape of the flexible display device is sensed (S2901).

Then, it is determined whether the shape of the flexible display device corresponding to the gesture detected in the application icon display state is a pre-stored shape (S2902). If it is a pre-stored shape (S2902: Y), the application corresponding to the sensed gesture is driven (S2903).

Also, it is determined whether the shape of the flexible display device corresponding to the sensed gesture detected in the application driving state is a pre-stored shape (S2904). If it is a pre-stored shape (S2904: Y), the function of the driven application corresponding to the sensed gesture is performed (S2905)

In the flexible display device according to the second embodiment of the present invention, if the pre-stored shape is transformed into a pre-stored shape, the application corresponding to the pre-stored shape can be directly performed, thereby improving user convenience.

# 3: Third Embodiment

54 is a block diagram showing a flexible display device according to the third embodiment of the present invention. 54, a flexible display device 300 according to an embodiment of the present invention includes a display unit 310, a sensing unit 320, a control unit 330, a storage unit 340, and an actuator unit 350 Or portions thereof. However, in the description of FIG. 30, a detailed description of the configuration described above will be omitted.

The sensing unit 320 senses the touch of the user. In addition, the sensing unit 320 may sense a grip region according to a user's gripping operation

The control unit 330 controls the overall operation of the flexible display device 300. More specifically, the control unit 330 may control all or a part of the display unit 310, the sensing unit 320, the actuator unit 340, and the storage unit 350.

In particular, the control unit 330 may control the actuator unit 350 so that the shape of the input device may be deformed according to a driven application. For example, if the driven application is an airplane game and the required input device shape is a joystick shape, the control unit 330 can control the actuator unit 350 so that the flexible display device 300 is rolled. Or the driven application is a golf game and the required input device shape is a golf club shape, the control unit 330 can control the actuator unit 350 so that the flexible display device 300 is rolled. The control unit 330 may control the actuator unit 350 so that the flexible display device 300 is rolled when the driven application is a bow game and the required input device shape is an arc shape.

However, the present invention is not limited to this, and it is possible to control the actuator unit 350 so that the actuator unit 350 deforms in different shapes according to the driven application, and even when the content type of the driven application is not a game type, It is possible to control the actuator unit 350 so that the actuator unit 350 is moved.

Here, the input device shape required according to the application may be stored in the storage unit 350 for each application. Or in a drive program form from the application provider side.

In the case where the actuator unit 340 is a plurality of polymer-based materials, as shown in FIG. 25, in order to manipulate the shape deformation of the flexible display device 300, the controller 330 controls the voltage of the plurality of polymer- It is possible to control at least one of the application order and the magnitude of the applied voltage so as to be transformed into a predetermined shape. Accordingly, the flexible display device 300 can be deformed automatically and can maintain a deformed shape. When the actuator unit 340 is a string, in order to manipulate the shape deformation of the flexible display device 300, the control unit 330 changes the tension of the string so that the flexible display device 300 can be moved in a predetermined shape It can be controlled to be deformed. Accordingly, the flexible display device 300 can be deformed automatically and can maintain a deformed shape.

Further, when the shape of the flexible display device 300 is deformed, the controller 330 controls the touch of the predetermined area to be activated according to the deformed shape. For example, when the driven application is an airplane game, the control unit 330 can control the actuator unit 350 so that the flexible display device 300 is shaped into a roll shape, and the roll- So that a touch on one area of the upper part of the touch panel 300 is activated.

In this case, the control unit 330 may control the display unit 310 to display the area where the touch is activated. In this case, the user can know the area where the touch is activated, and by performing a touch on this area, the flexible display device 300 can be used as an input device.
