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

1 is a block diagram illustrating a configuration of a flexible display device according to an embodiment of the present invention. The display device 100 of FIG. 1 is portable, such as a mobile phone, a smart phone, a PMP, a PDA, a tablet PC, and a navigation system, and can be implemented as a stationary device such as a monitor, TV, and kiosk as well as various types of portable devices having a display function. May be. Referring to FIG. 1, the flexible display apparatus 100 includes all or part of the display unit 110, the sensing unit 120, and the control unit 130. However, prior to describing FIG. 1, a detailed configuration of the display unit 110 and a method of detecting bending thereof will be described in detail.

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

A flexible display device refers to a device that can be bent, bent, folded, or rolled like 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 may be implemented as a plastic substrate (eg, a polymer film) that can be deformed by external pressure.

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

* On the other hand, as the substrate 111, in addition to a plastic substrate, a material having flexible properties such as thin glass or metal foil may be used.

The driving unit 112 functions to drive the display panel 113. Specifically, the driver 112 applies 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 organic TFT (OTFT), or the like. have. The driving unit 112 may be implemented in various forms according to the implementation type of the display panel 113. For example, the display panel 113 may include an organic light-emitting body including a plurality of pixel cells and an electrode layer covering both surfaces of the organic light-emitting body. In this case, the driver 112 may include a plurality of transistors corresponding to each pixel cell of the display panel 113. The controller 130 applies an electric signal to the gate of each transistor to emit light of the pixel cell connected to the transistor. 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 disply (LCD), an AMLCD, a plasma display panel (PDP), in addition to an organic light emitting diode. However, in the case of an LCD, a separate backlight is required because it cannot emit light by itself. In the case of LCDs where the backlight is not 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, a material such as ZrO, CeO2, or Th O2 may be used for the protective layer 114. The protective layer 114 may be manufactured in the form of a transparent film to cover the entire surface of the display panel 113.

Meanwhile, unlike FIG. 2, the display unit 110 may be implemented with electronic paper. Electronic paper is a display in which the characteristics of general ink are applied to paper, and is different from a general flat panel display in that it uses reflected light. On the other hand, electronic paper can change pictures or characters using a twist ball or electrophoresis using a capsule.

Meanwhile, when the display unit 110 is made of a component made of a transparent material, it may be implemented as a display device capable of bending and having a transparent property. For example, when the substrate 111 is implemented with a polymer material such as plastic having a transparent property, the driver 112 is implemented with a transparent transistor, and the display panel 113 is implemented with a transparent organic light emitting layer and a transparent electrode, transparency is achieved. I can have it.

The transparent transistor refers to a transistor manufactured by replacing the opaque silicon of the existing thin film transistor with a transparent material such as transparent zinc oxide and titanium oxide. In addition, new materials such as indium tin oxide (ITO) or graphene may be used for the transparent electrode. Graphene refers to a material having a transparent property with carbon atoms connected to each other to form a honeycomb-shaped planar structure. In addition, the transparent organic light emitting layer may also be implemented with various materials. FIGS. 3 to 5 illustrate an example of a method of detecting shape deformation, that is, bending in a flexible display device according to an embodiment of the present invention. It is a drawing for.

The flexible display device 100 may be bent by external pressure and thus its shape may be deformed. Bending may include general bending, folding, and rolling. Normal bending refers to a state in which the flexible display device is bent, and is different from folding and rolling in that the bent surfaces do not contact 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, when bending is performed beyond a certain radius of curvature, it is defined as a folded state, and when bending is performed below the radius of curvature, it may be defined as general bending.

Rolling refers to a state in which the flexible display device is rolled. Rolling can also be determined based on the radius of curvature. For example, a state in which bending over a predetermined radius of curvature is continuously detected over a predetermined area may be defined as rolling, and a state in which bending over a predetermined radius of curvature is detected in a relatively small area may be defined as folding.

However, the definition of various examples of shape modification as described above is only an example, and may be defined differently according to the type, size, weight, and characteristics of the flexible display device. For example, if the surfaces of the flexible display device 100 can be bent enough to contact each other, 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 and rear surfaces of the flexible display device are in contact with each other due to bending.

For convenience of description, in the present specification, these various types of bending and other types of bending are collectively referred to as bending.

The flexible display device 100 may detect bending in various ways.

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

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

The detection unit 120 detects 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 the bending state at the position of the corresponding bend sensor according to the magnitude of the resistance value. Can be detected.

3 shows a state in which the bend sensor is embedded in the front surface of the display unit 110, but this is only an example, and the bend sensor may be embedded in the rear surface of the display unit 110 or both sides. . In addition, the shape, number, and arrangement position of the bend sensors may be variously changed.

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 grid shape.

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

3 shows that five bend sensors 21-1 to 21-5 and 22-1 to 22-5 are disposed in each of the horizontal and vertical directions, but this is only an example and depends on the size of the flexible display device. Of course, the number of bend sensors can be changed. As described above, since the bend sensor is arranged in the horizontal and vertical directions to detect bending that occurs throughout the flexible display device, in the case of a device that has a characteristic that is only partially flexible or that it is necessary to detect bending of only a portion In, the bend sensor may be disposed only in the corresponding part.

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

Specifically, as shown in FIG. 4, when the center area located at the center thereof is bent downward with respect to the left and right edges of the flexible display device 100, the bend sensors in which the tension caused by the bending is disposed in the horizontal direction ( 21-1 to 21-5). Accordingly, the resistance values of the bend sensors 21-1 to 21-5 arranged in the horizontal direction vary. The detection unit 120 may detect a change in output values output from each of the bend sensors 21-1 to 21-5, and detect that bending is made in the horizontal direction based on the center of the display surface. 4 illustrates a state in which the center region is bent in a downward direction perpendicular to the display surface (hereinafter referred to as Z-direction), but in an upward direction perpendicular to the display surface (hereinafter referred to as Z+ direction). Even if it is bent in the horizontal direction, it can be detected based on a change in the output value of the bend sensors 21-1 to 21-5 in the horizontal direction.

In addition, as shown in FIG. 5, when the shape of the flexible display device 100 is bent so that the central region located at the center thereof faces upward with respect to the upper and lower edges, the bend sensors 22- 1 to 22-5). The detector 120 may detect a shape deformation in the vertical direction based on the output values of the bend sensors 22-1 to 22-5 arranged in the vertical direction. Although bending in the Z+ direction is shown in FIG. 5, it goes without saying that the bending in the Z- direction can also be detected using the bend sensors 22-1 to 22-5 arranged in the vertical direction.

On the other hand, in the case of shape deformation in the diagonal direction, since tension is applied to both the bend sensors arranged in the horizontal and vertical directions, the shape deformation in the diagonal direction can also be detected based on the output values of the bend sensors arranged in the horizontal and vertical directions. I can.

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

6 to 8 are diagrams for explaining a method of detecting bending in a flexible display device using a bend sensor according to 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 or both sides of the flexible display device are also bent to have a resistance value corresponding to the strength of the applied tension, and output an output value corresponding thereto.

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

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 center region becomes the largest. Accordingly, the greatest tension acts on the bend sensor 31-1 disposed at the point a3, which is the central region, and accordingly, the bend sensor 31-1 has the largest resistance value. On the other hand, the degree of bending becomes weaker as it goes outward. Accordingly, the bend sensor 31-1 has a resistance value smaller than the point a3 as it goes to the points a2 and a1, or the points a4 and a5 based on the point a3.

When the resistance value output from the bend sensor has a maximum value at a specific point and the resistance value outputted gradually decreases toward both directions, the detection unit 120 determines that the region in which the maximum resistance value is detected is the region in which the largest bending has occurred. can do. In addition, the sensing unit 120 may determine that the region in which the resistance value is not changed is a flat region in which bending is not performed, and the region where the resistance value is changed by a certain amount or more is a bending region in which even slight bending has occurred. .

7 and 8 are diagrams for explaining a method of defining a bending area according to an embodiment of the present invention. 7 and 8 are diagrams for explaining a case where the flexible display device is bent in the horizontal direction with respect to the front surface, for convenience of explanation, bend sensors disposed in the vertical direction are not shown. In addition, for convenience of description, reference numerals for each bend sensor are given differently for each drawing, but in reality, bend sensors such as the structure shown in FIG. 3 may be used as it is.

The bending area refers to an area where the flexible display device is bent and bent. Since the bend sensors are bent together by bending, the bending area may be defined as all points in which the bend sensors outputting resistance values different from those in the original state are disposed.

The sensing unit 120 may detect the size of the bending area, the direction of the bending line, the position of the bending area, the number of bending areas, and the like, based on the relationship between the points at which the resistance value change is sensed.

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

7 is a diagram for describing a method of detecting one bending area. As shown in FIG. 7, when the flexible display device 100 is bent, the bend sensor 31-from point a1 to point a5 of the bend sensor 31-1, from point b1 to point b5 of the bend sensor 31-2, From the point c1 to the point c5 of 3), from the point d1 to the point d5 of the bend sensor 31-4, and from the point e1 to the point e5 of the bend sensor 31-5, the resistance values are different from those in the original state.

In this case, the points at which the resistance value change is detected by each of the bend sensors 31-1 to 31-5 are located within a preset distance from each other and are continuously arranged.

Therefore, the detection unit 120 is from the point a1 to the point a5 in the bend sensor 31-1, from the point b1 to the point b5 in the bend sensor 31-2, and from the point c1 to the point c5 in the bend sensor 31-3. Up to the point, the bend sensor 31-4 detects an area 32 including all points from d1 to d5, and the bend sensor 31-5 from the point e1 to the point e5 as one bending area.

8 is a diagram for describing a method of detecting a plurality of bending areas.

In FIG. 8, according to the bending of the flexible display device, from points a1 to a2 and from points a4 to a5 of the bend sensor 31-1, from points b1 to b2 and points b4 of the bend sensor 31-2. From the point b5, from the point c1 to the point c2 of the bend sensor (31-3) and from the point c4 to the point c5, from the point d1 to the point d2 of the bend sensor (31-4) and from the point d4 to the point d5, bend From the point e1 to the point e2 and from the point e4 to the point e5 of the sensor 31-5 have different resistance values than in the original state.

In the bend sensor (31-1), points a1 to a2 and points a4 to a5 are continuous when viewed based on each point, but point a3 exists between points a2 and a4, so points a2 to a4 are not continuous. not. Accordingly, assuming that the distance from the point a2 to the point a4 is separated by a predetermined distance, the points a1 to a2 and the points a4 to a5 may be divided into different bending areas. In addition, each point of the other bend sensors 31-2 to 31-5 may be divided in the same manner.

Accordingly, the flexible display apparatus 100 is configured from a point a1 to a point a2 in the bend sensor 31-1, from a point b1 to a point b2 in the bend sensor 31-2, and from a point c1 in the bend sensor 31-3. An area 34 including all points from point c2, point d1 to point d2 in the bend sensor 31-4, and point e1 to e2 in the bend sensor 31-5 is defined as one bending area, From the point a4 to the point a5 in the bend sensor 31-1, from the point b4 to the point b5 in the bend sensor 31-2, from the point c4 to the point c5 in the bend sensor 31-3, the bend sensor 31- In 4), an area 35 including all points from d4 to d5 and points e4 to e5 in the bend sensor 31-5 may be defined as another bending area.

Meanwhile, the bending area 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, the point a3 outputs the largest resistance value in the bending area 33, the point b3 outputs the largest resistance value in the bend sensor 31-2, and the largest resistance value in the bend sensor 31-3. A line (33) connecting the point c3 that outputs the resistance value, the point d3 that outputs the largest resistance value from the bend sensor (31-4), and the point e3 that outputs the largest resistance value from the bend sensor (31-5) Can be defined as a bending line. 7 shows a state in which a bending line is formed in a vertical direction in a central area of the display surface.

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

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

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

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

For example, as shown in FIG. 9, when the right edge area of the flexible display device 100 is folded toward the center, the bend sensor 41-1 disposed on the back side of the flexible display device 100 is also bent and applied. Paper outputs the resistance value according to the magnitude of the tension.

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

Meanwhile, when folding in which the flexible display device is bent beyond a certain radius of curvature is performed, a resistance value is sensed to have a size greater than or equal to a certain size at a point corresponding to the bending line. Accordingly, the controller 130 may determine whether it is folding or general bending according to the size of the resistance value.

Alternatively, if the surfaces of the flexible display device 100 can be bent enough to contact each other, the controller 130 may determine whether to fold in consideration of whether or not a touch is made. That is, as shown in FIG. 9, when the right edge of the flexible display device 100 is bent in the Z+ direction and folded to the front surface, regions spaced apart from each other on the front surface of the flexible display device 100 come into contact with each other. In this case, a touch is sensed in one area of the display surface, and the degree of change of the resistance value is also greater than that of general bending. Accordingly, the control unit 130 calculates the distance from the bending edge boundary to the bending line, and then determines that folding has occurred when a touch is sensed at a point separated by a distance calculated in the opposite direction with respect to the bending line. can do. 10 is a diagram illustrating a method of determining a folding area according to an embodiment of the present invention. In the case of FIG. 10, since it is a diagram for explaining a case in which the flexible display device is folded in the horizontal direction with respect to the front surface, bend sensors disposed in the vertical direction for convenience of description are not illustrated.

The folding area is a bent area formed as the flexible display device is folded. As in the case of bending, as the bend sensor is bent, it is one or more areas including all points of the bend sensor that output a different resistance value from the original state. Can be defined. Since the method of defining and classifying the folding area is the same as in the bending area, redundant description will be omitted.

Referring to FIG. 10, the output resistance value is different from the original state, that is, from the point a1 to the point a5 in the bend sensor 41-1, from the point b1 to the point b5 in the bend sensor 41-2, An area including all points from c1 to c5 in the bend sensor 41-3, from d1 to d5 in the bend sensor 41-4, and from e1 to e5 in the bend sensor 41-5 ( 42) can be defined as one folding area.

The folding area is divided into two based on the folding line. The folding line may be defined as a line connecting points that output the largest resistance value in each folding area. The folding line may have the same meaning as the bending line.

In the case of FIG. 10, in the folding area 42, a point a3 that outputs the largest resistance value from the bend sensor 41-2, a point b3 that outputs the largest resistance value from the bend sensor 41-2, and the bend sensor ( Point c3 where the largest resistance value is output in 41-3), point d3 where the largest resistance value is output from the bend sensor (41-4), point e3 where the largest resistance value is output from the bend sensor (41-5) The line 43 connecting the is a folding line.

When folding is detected, the controller 130 may perform an operation different from that of normal bending. For example, an operation such as displaying different content screens for each folding area may be performed.

Meanwhile, as described above, the flexible display device 100 may be rolled like paper. The control unit 130 may determine whether rolling has been performed using the result detected by the detection unit 120.

11 to 13 are diagrams for explaining a method of sensing rolling by a flexible display device.

First, FIG. 11 shows a cross-sectional view when the flexible display device 100 is rolled.

As described above, when the flexible display device 100 is rolled, tension acts on bend sensors disposed on one or both sides of the flexible display device.

In this case, since the strength of the tension applied to the bend sensor can be considered to be close to each other within a certain range, resistance values output from the bend sensor are also close to each other within a certain range.

In order for rolling to occur, bending must be performed with a certain curvature or more. In addition, when rolling is performed, the bending area is formed larger than in the case of general bending or folding. Accordingly, if the controller 130 detects that bending of a certain radius of curvature or more has been continuously performed in an area of a certain size or more, it may be determined as a rolling state. In addition, in the rolling state, the front and rear surfaces of the flexible display device are in contact with each other. It is done. For example, as shown in FIG. 11, when one edge of the flexible display device 50 is bent in the Z+ direction and rolled into the display surface, the display surface, that is, the front surface and the rear surface on which the bend sensor 50-1 is disposed, are They come into contact with each other.

Accordingly, in an example different from that described above, the controller 130 may determine whether the flexible display device is in a rolling state according to whether the front and rear surfaces of the flexible display device are in contact with each other. In this case, the sensing unit 120 may include a touch sensor. The control unit 130 is a touch sensor in which resistance values output from the bend sensor approximate each other within a certain range, and are disposed on the front and rear surfaces of the flexible display device. When each touch is sensed in the fields, it may be determined that the flexible display device is rolled.

12 and 13 are diagrams for explaining a method of defining a rolling area according to an embodiment of the present invention.

The rolling area refers to the entire area in which the flexible display device is bent and in a rolling state. The rolling region may also be defined as one or two or more regions including all points of the bend sensor that outputs a resistance value different from that in the original state, as in the case of general bending and folding. Since the method of defining and dividing the rolling area is the same as in the bending and folding area, redundant description will be omitted.

As shown in FIG. 12, when the flexible display device 50 is entirely rolled, the entire area 51 of the flexible display device may be defined as a rolling area. As shown in FIG. 13, the flexible display device 100 is partially rolled and When a point for outputting a resistance value different from that in the state is separated by a predetermined distance, some areas 52 and 53 of the flexible display device may be defined as different rolling areas.

As described above, the flexible display apparatus 100 may be bent in various shapes, and the controller 130 may detect each bending shape based on the detection result of the detection unit 120. In addition, the controller 130 may detect a degree of bending, that is, a bending angle, based on the detection result of the detection unit 120.

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

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

Specifically, the control unit 130 calculates a difference between a resistance value at a point where the bend sensor outputs the largest resistance value and a resistance value output at a point spaced apart from the point by a predetermined distance.

In addition, the control unit 130 may determine the degree of bending by using the calculated difference in resistance value. Specifically, the flexible display apparatus 100 may divide the bending degree into a plurality of levels, and may match and store a resistance value having a certain range for each level.

Accordingly, the flexible display apparatus may determine the bending degree of the flexible display apparatus according to a level belonging to a plurality of levels divided according to the bending degree of the calculated resistance value difference.

For example, as shown in FIGS. 14 and 15, a resistance value output from a point a5 outputting the largest resistance value from a bend sensor 61 provided on the rear side of the flexible display device 100 and a predetermined distance apart The degree of bending may be determined based on the difference in the resistance value output at the point a4.

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

On the other hand, since the embodiment shown in FIG. 15 has a higher bending degree than that of the embodiment shown in FIG. 14, the resistance value output from the bending sensor point a5 and the resistance value output from the point a4 in the embodiment shown in FIG. The difference is greater than the difference between the resistance value output from the bending sensor point a5 and the resistance value output from the point a4 in the embodiment illustrated in FIG. 14. Accordingly, when the control unit 130 is bent as shown in FIG. 15, it may 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, in the case of performing a channel zapping operation, if the degree of bending is large, the channel zapping speed may be increased or the channel zapping range may be increased. On the other hand, if the bending degree is low, channel zapping may be performed more slowly and in units of a smaller number of channels. Even when an operation such as volume control or content conversion is performed, the operation may be performed differently depending on the degree of bending.

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

* The bending direction can also be sensed in various ways. As an example, by arranging two bend sensors to overlap, the bending direction may be determined according to a difference in the size change of the resistance value of each bend sensor. In FIGS. 16 to 18, a method of detecting a bending direction using an overlapped bend sensor will be described.

For convenience of explanation, in FIGS. 16 to 18, a case of general bending will be described as an example. However, it goes without saying that folding and rolling can also be applied in the same way as bending.

Referring to FIG. 16, two bend sensors 71 and 72 may be provided on one side of the display unit 110 to overlap each other. In this case, when bending is performed in one direction, 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, by comparing the resistance values of the two bend sensors 71 and 72 at the same point, the bending direction can be known.

Specifically, as shown in FIG. 17, when the flexible display device 100 is bent in the Z+ direction, a higher tension is applied to the lower bend sensor 72 than the upper bend sensor 71 at a point A corresponding to the bending line. You lose.

On the contrary, when the flexible display device 100 is bent in the rearward direction as shown in FIG. 18, a higher tension is applied from the upper bend sensor 71 than the lower bend sensor 72.

Accordingly, the controller 130 may detect the bending direction by comparing resistance values corresponding to point A by the two bend sensors 71 and 72.

In FIGS. 16 to 18, two bend sensors overlap each other on one side of the display unit 110, but the bend sensors may be disposed on both sides of the display unit 110.

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

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

Meanwhile, in FIGS. 16 to 19, it has been described that the bending direction is sensed using two bend sensors, but the bending direction may be distinguished by only a stress gauge disposed on one surface of the display unit 110. That is, since the strain gauge disposed on one side is applied with a compressive force or a tensile force according to its bending direction, it is possible to know the bending direction by checking 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. According to FIG. 20, the bend sensor 71 may be implemented in a shape of a closed curve forming a circle or a square or other polygon, and may be disposed at the edge of the display unit 110. The control unit 130 may determine a point at which a change in the output value is detected on the closed curve as a bending area. In addition, the bend sensor may be combined with the display unit 110 in the form of an open curve such as an S-shape and a zigzag “Z”.

21 shows an embodiment in which two bend sensors are disposed to cross each other. Referring to FIG. 21, the first bend sensor 71 is disposed on the first surface of the display unit 110, and the second bend sensor 72 is disposed on the second surface of the display unit 110. The first bend sensor 71 is disposed in a first diagonal direction on the first surface of the display unit 110, and the second bend sensor 72 is disposed in a second diagonal direction from the second surface. Accordingly, when each corner region is bent, each edge region is bent, the center portion is bent, folding or rolling is performed, the first and second bend sensors 71 and 72 are Since the output value and the output point are different, the controller 130 may determine what type of bending has been performed according to the characteristics of the output value.

* On the other hand, in the various embodiments described above, a case in which line-type bend sensors are used is illustrated, but bending may be sensed by using a plurality of fragmentary strain gauges.

22 and 23 are diagrams illustrating an embodiment of detecting bending using a plurality of strain gauges.

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

In the state in which the strain gauges are 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 gauge 80-x overlapping the bending line among the strain gauges 80-1 to 80-n disposed in the horizontal direction. Accordingly, the output value of the strain gauge 80-x becomes larger than the output value of other strain gauges. In addition, among the strain gauges 80-n, 80-n+1, and ~~ 80-m arranged in the vertical direction, a force acts on the strain gauge 80-y overlapping the bending line, so that 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 are changed is a bending line.

Alternatively, unlike FIGS. 17 to 23, the flexible display device 100 may detect the bending direction using various sensors such as a gyro sensor, a geomagnetic sensor, and an acceleration sensor.

24 and 25 are diagrams for explaining a method of detecting a bending direction using an acceleration sensor as an example of such sensors. 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 capable of measuring acceleration and a direction of acceleration when a motion occurs. Specifically, the acceleration sensors 81-1 and 81-2 output sensing values corresponding to the gravitational acceleration that changes according to the inclination of the device to which the sensor is attached. Therefore, if the acceleration sensors 81-1 and 81-2 are respectively disposed in the edge areas on both sides 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 Is changed. The controller 130 calculates a pitch angle and a roll angle by using the output values sensed by the acceleration sensors 81-1 and 81-2. Accordingly, the bending direction may be determined based on the degree of change in the pitch angle and the roll angle sensed by the acceleration sensors 81-1 and 81-2.

Meanwhile, in FIG. 24, the flexible display apparatus 100 shows a state in which acceleration sensors 81-1 and 81-2 are disposed at both edges in the horizontal direction with respect to the front surface, but in the vertical direction as in FIG. 25. It can also be placed. In this case, when the flexible display device 100 is bent in the vertical direction, the bending direction may be detected according to a measurement value detected by each acceleration sensor 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 upper and lower edges of the flexible display device 100, the acceleration sensor may be disposed at both the upper, lower, left and right edges, or may be disposed in the corner area. .

As described above, in addition to the acceleration sensor, the bending direction may be detected using a gyro sensor or a geomagnetic sensor. The gyro sensor is a sensor that detects the angular velocity by measuring the Coriolis force acting in the direction of the velocity when a rotational motion occurs. According to the measured value of the gyro sensor, since it is possible to detect in which direction the rotation is made, the bending direction can be detected. The geomagnetic sensor is a sensor that detects the azimuth angle using a 2-axis or 3-axis fluxgate. When implemented as a geomagnetic sensor, the geomagnetic sensor disposed at each edge of the flexible display device 100 moves its position when its edge portion is bent, and outputs an electrical signal corresponding to the geomagnetic change. The controller 130 may calculate a yaw angle using a value output from a geomagnetic sensor. Accordingly, various bending characteristics such as a bending area and a bending direction may be determined according to a change in the calculated yaw angle.

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

Meanwhile, in addition to bending, the sensing unit 120 may detect an operation in which the user touches the screen of the display unit 110.

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 thereon. Accordingly, when the user touches the screen, the upper and lower plates of the touched point are contacted, and an electrical signal is transmitted to the controller 130. The controller 130 recognizes the touch point by using the coordinates of the electrode to which the electrical signal is transmitted. Since the touch sensing method has been known in various prior literatures, further detailed descriptions will be omitted.

When a touch or bending is detected, the controller 130 determines whether a user manipulation such as touch or bending is intended. Hereinafter, various embodiments of the present invention will be described in more detail using a detailed configuration of the display unit 110 and a bending detection method therefor.

#1: first embodiment

The display unit 110 displays a screen. In more detail, the display unit 110 may display at least one application icon. In addition, the display unit 110 may display an application driving screen. In addition, the display unit 110 may provide a guide for at least one bending gesture for driving an application corresponding to the selected application icon. In addition, the display unit 110 may provide a guide for at least one bending gesture for performing a preset function of the driven application. Here, since folding and rolling are performed only when bending is performed, in describing various embodiments of the present invention, the bending gesture is defined as a concept including both a folding gesture and a rolling gesture.

The sensing unit 120 may detect a bending gesture that bends the flexible display device 100. Here, the sensing unit 120 may be implemented with various types of bend sensors, and the arrangement and detection method of the bend sensors have been described above, and a detailed description thereof will be omitted.

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

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

In more detail, the controller 130 may determine whether 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, when it is determined that bending of the flexible display apparatus 100 is necessary, 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 Jenga game application, the flexible display device 100 must be transformed into a shape of a square pillar. Therefore, the controller 130 determines that the shape of the flexible display device 100 needs to be in the shape of a square pillar in order to drive the Jenga game application. Can provide.

In addition, the controller 130 detects a user's bending gesture for bending of the flexible display device 100 through the detection unit 120, and the detected bending gesture is a preset bending for driving an application corresponding to the selected application icon. If it is determined as a gesture, an application corresponding to the selected application icon may be driven. Taking the above-described Jenga game as an example, the controller 130 may drive the Jenga game application if the shape of the flexible display device 100 deformed according to the user's bending gesture is a preset shape for driving the Jenga game application. have.

In addition, the control unit 130 detects a plurality of bending gestures of the user for bending the flexible display device through the sensing unit 120, and transforms the flexible display device 100 into a preset shape using a plurality of detected bending gestures. When it is determined that the application is successful, an application corresponding to the selected application icon may be driven. That is, if the Jenga game described above is described as an example, in the provided guide, the user may repeat the bending gesture of bending and blood. However, even in this case, the controller 130 may drive the Jenga game application if the shape of the flexible display device 100 deformed according to the user's bending gesture is a preset shape for driving the Jenga game application.

In addition, when it is determined that bending of the flexible display apparatus 100 is not necessary, the controller 130 may not provide a guide and may drive an application corresponding to the selected application icon. For example, in order to drive an SNS application, the shape of the flexible display device 100 is not necessarily deformed. In this case, the controller 130 may run the selected SNS application without providing a separate guide.

In addition, the controller 130 may provide a guide for at least one bending gesture for performing a preset function by the driven application.

In more detail, the controller 130 may determine whether bending of the flexible display device is necessary in order for the driven application to be performed with a preset function.

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

In addition, when the user's bending gesture for bending of the flexible display device is detected through the detection unit 120 and the detected gesture is determined as a preset gesture for the driven application, the driven application is a preset function. Can be controlled to be performed. Taking the above-described piano application as an example, if the shape of the flexible display device 100 deformed according to the user's gesture is a preset shape for providing a sheet music function in the driven piano application, the display unit 110 You can provide a score function in one area of ).

In addition, the controller 130 detects a plurality of bending gestures of the user for bending the flexible display device 100 through the sensing unit 120, and the flexible display device 100 is configured by using a plurality of detected bending gestures. When it is determined that it has been transformed into a set shape, the driven application may be controlled to be executed with a preset function. That is, when the above-described piano application is described as an example, in the provided guide, the user may repeat the bending gesture of bending and blood. However, even in this case, if the shape of the flexible display device 100 deformed according to the user's bending gesture is a preset shape for providing a sheet music function in the driven piano application, the control unit 130 In addition, the control unit 130 performs different operations according to the number of bendings detected through the detection unit 120, that is, the number of times the bending has been repeatedly performed, such as 1, 2, 3, etc. Or you can do the same. For example, when bending is performed once, page switching may be performed, content switching may be performed when bending is performed twice in a row, and application switching may be performed when bending is performed three times in a row. Alternatively, the controller 130 may perform the same function when the shape of the flexible display device 100 modified by a bending gesture such as 1st, 2nd, 3rd, etc. is the same.

In addition, the controller 130 may perform different operations or perform the same operation according to whether the bending gesture sensed through the sensing unit 120 is a sequential bending gesture or a simultaneous bending gesture. Here, the sequential bending gesture means performing bending according to the provided first guide and then performing bending according to the provided second guide. In addition, the simultaneous bending gesture means performing bending simultaneously according to the provided first guide and the provided second guide. In this case, even if the shape of the flexible display device 100 deformed by the bending gesture is the same, the controller 130 performs a first function in case of a sequential bending gesture, and performs a second function in case of a simultaneous bending gesture. I can. Alternatively, the controller 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 the driven content is GALLERY or MOVIE, the controller 130 may provide a guide for a user to view an optimized screen. In this case, the controller 130 may provide a guide using resolution information of the driven gallery or movie. In addition, when the type of the driven content is GAME, the controller 130 may provide a guide for optimizing the interaction with the user. In this case, the controller 130 may provide a guide using the type of the driven GAME. For example, when the driven GAME is an airplane game, the controller 130 may 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 inducing a user-friendly GRIP according to the type of content.

In addition, the controller 130 may provide a guide to be executed immediately when NOTIFICATION, RSS, or the like is received. For example, when a text comes from the other party, the controller 130 may provide a guide through which the text can be immediately checked.

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

In addition, when a user's bending gesture for bending of the flexible display device is detected through the detection unit 120, the controller 130 compares the detected bending gesture with a preset gesture for the driven application, and provides a comparison result. I can.

Here, the comparison result may be feedback of the accuracy of the detected bending gesture. In addition, the feedback on the accuracy of the detected bending gesture may be feedback on the success of the bending gesture, the failure of the bending gesture, and the completion of the bending gesture. Here, feedback may be any method of providing accuracy of a bending gesture to a user, such as haptic feedback such as vibration, sound feedback, and GUI feedback such as a pop-up window. For example, if it is determined that the detected bending gesture is not a preset gesture, the controller 130 provides vibration feedback to the user (here, the vibration feedback is a case where vibration feedback is given only to the area to be bent, or a vibration feedback is provided to the whole Yes), or a sound such as'The bending area is wrong', or a text-shaped pop-up window can be provided. In addition, if it is determined that the detected bending gesture is a preset gesture, the controller 130 may provide a vibration feedback to the user, a sound of “the bending area is correct,” or a text-shaped pop-up window. In this case, the controller 130 may provide a guide for inducing a correct bending gesture again.

In addition, when the detected bending gesture is determined to be a preset gesture and a corresponding operation is performed accordingly, the provided guide may not be displayed, thereby indicating that the operation is being performed according to the bending gesture.

Accordingly, the user can easily know whether the bending gesture is accurate.

In addition, the guide here is a guide that displays a bending/folding line, a guide that displays a bending/folding direction, a guide that displays rolling, a guide through haptic feedback, and shape transformation and It may be provided in the shape of at least one of the related manual guides. In addition, when the flexible display apparatus 100 includes an actuator unit, the guide may be a guide that induces a bending operation while squeezing at a position where bending is to be performed.

Specifically, the guide for displaying the bending/folding line may be displayed with various lines. For example, a dotted line or a solid line may be used. In addition, different lines may be mapped for each bending area or folding area. For example, the bending area may be mapped with a dotted line and the polling area may be mapped with a solid line. In addition, the bending/folding lines may be displayed in different colors or different thicknesses, and may be mapped to a bending area or a folding line, or mapped to a bending/folding angle or a bending/folding direction.

For example, a bending area may be mapped to black and a folding line may be mapped to red. Alternatively, 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 a direction opposite to the user. Alternatively, the black line may be mapped to a bending area corresponding to the 60 degree bending gesture, and the red line may be mapped to a bending area corresponding to the 30 degree bending gesture. However, it is not limited thereto and may be mapped in various ways. Alternatively, the bending/folding line may be displayed using light. For example, the bending area may be mapped to light that is continuously turned on (ie, light without flicker), and the folding line may be mapped to light that is repeatedly turned on/off (ie, light that blinks).

In addition, guides indicating the bending/folding direction may be displayed with various symbols such as arrows. For example, the bending/folding direction may be indicated using the direction of an arrow.

In addition, a guide indicating rolling may be displayed with various symbols. For example, it can be displayed as an arrow, text, or line indicating a rolling motion.

In addition, a guide through haptic feedback may be provided in a shape such as vibration in a region including a bending/folding line.

In addition, a manual guide related to shape deformation may be provided as a manual such as text, sound, or video. For example, in the case of text, it may be provided as a textual description such as "Bend the dotted line inward 60 degrees, and the solid line 30 degrees outward", sound description through sound, bending/folding/rolling It may be provided as a video instruction explaining the operation.

Here, the guide may display an operation to be performed together with or after the bending gesture. For example, the guide may be displayed along with the number of bendings. That is, the number of times that bending should be repeatedly performed in the guide, such as 1, 2, 3, etc., can be displayed.

In addition, the guide includes a FLAP gesture (a gesture to perform a bending/folding/rolling gesture and come back to its place), a HOLD gesture (a gesture to perform and hold a bending/folding/rolling gesture), and a MOVE gesture (a bending/folding/rolling gesture and its status). It may indicate that a gesture of moving the bending line in a certain direction) should be performed. For example, in the case of a driven e-book application, it may be provided that a FLAP gesture must be performed on a right corner portion to switch to a next page, and a FLAP gesture must be performed together with a guide. In addition, in the case of a Jenga game application, it may be provided that in order to execute the Jenga application, a HOLD gesture for making a square pillar shape should be performed, and a HOLD gesture should be performed together with a guide. However, it is not limited to the above-described example, and the user's bending gesture may be mapped differently for each application. Also, the number of gestures may be mapped differently for each application.

In addition, 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 erected, whether it should be laid down, etc. together with the guide or after the flexible display apparatus 100 is deformed. have.

Here, the guide is displayed based on a bending area belonging to a preset bending range, and the preset bending range may be set to include a preset 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 the flexible display device 100 at an accurate guide position. Accordingly, the guide may be set to include a preset error range, and the bending area may be displayed within a preset error range. In addition, when a bending/folding/rolling gesture is input within a preset error range, the controller 130 may determine the gesture as a preset gesture for the application.

In addition, when the flexible display device 100 is converted to a standby state and the display unit 110 displays a standby screen including an application icon, the controller 130 performs at least one bending gesture related to a function executable in the standby state. You can provide a guide on how to do it. Accordingly, when a bending gesture corresponding to the provided guide is performed, the controller 130 may perform an operation corresponding to the bending gesture. For example, the controller 130 may provide a guide for at least one bending gesture related to execution of a function of unlocking a flexible display value related to a function executable on the lock screen. Accordingly, when a user performs a bending gesture mapped to each function, the controller 130 may control to perform a function corresponding thereto.

*

**In addition, when the flexible display device 100 is switched to the locked state, the controller 130 provides a guide for a bending gesture for unlocking, and when a bending gesture corresponding to the provided guide is performed, the unlocking is performed. I can. For example, the controller 130 provides a guide for at least one bending gesture related to execution of a flexible display device lock function, another standby screen display function, and a volume control function related to a function executable on the standby screen. Can provide. Accordingly, when a user performs a bending gesture mapped to each function, the controller 130 may control to perform a function corresponding thereto.

26 is a block diagram illustrating in detail the flexible display device according to FIG. 1. Referring to FIG. 26, the flexible display device 100 includes all or part of the display unit 110, the sensing unit 120, the control unit 130, the actuator unit 140, and the storage unit 150. However, in describing FIG. 10, a detailed description of the previously described configuration will be omitted.

The actuator unit 140 manipulates bending of the flexible display device 100. In more detail, the flexible display device 100 may be automatically bent, or the curved shape may be maintained. In addition, the flexible display apparatus 100 may be automatically bent to drive an application or to perform a specific function of the driven application. In addition, when the flexible display device 100 is bent in a shape corresponding to a bending gesture, it is maintained in a bent shape.

Here, the actuator unit 140 may be implemented with a plurality of polymer-based materials or strings arranged in a preset area of the flexible display device 100.

When the actuator unit 140 is made of a plurality of polymer-based materials, as shown in FIG. 49(a), in order to manipulate the shape deformation of the flexible display device 100, the controller 130 At least one of the order of applying the voltage and the magnitude of the applied voltage may be adjusted so as to be transformed into a preset shape. That is, in the polymer-based material, the upper part may contract and the lower part may be extended as shown in FIG. 49(a) according to at least one of an order of application of a voltage and a magnitude of the applied voltage. Accordingly, the flexible display device 100 may be automatically deformed in shape and also maintain the deformed shape. Here, the actuator unit 140 is located on the front or rear side of the flexible display apparatus as shown in FIG. 49(b). Can be built in. However, this is only an example, and the actuator unit 140 may be built into both sides 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 apparatus 100, the control unit 130 changes the tensile force of the string so that the flexible display apparatus 100 is transformed into a preset shape. It can be controlled as much as possible. Accordingly, the flexible display device 100 may be automatically transformed in shape, and may also maintain the transformed shape.

That is, when the shape is deformed by applying a physical force to the flexible display apparatus 100, the flexible display apparatus 100 receives a reverse force to return to its original flat shape. In this case, the actuator unit 140 provides a physical force corresponding to the reverse force under the control of the above-described controller 130 so that the flexible display device 100 maintains a deformed shape.

The storage unit 150 functions to store various programs and data necessary for driving the flexible display device 100.

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 map and store a bending gesture for performing a driven application as a preset function to each application.

Also, as in 33(a), the guide may be provided with light. Here, a line in which light is continuously on may mean bending in an inward direction, and a line in which on/off is repeated may mean bending in an outward direction. In this case, the user may bend the flexible display device 100 as shown in FIG. 33(b), and in this case, the flexible display device may be deformed as shown in FIG. 33(c).

That is, as shown in FIG. 36, a guide such as light, contrast, symbols, instructions, and the number of bending may be provided together. Here, when the user touches the guide, the controller 130 may provide a function mapped to the touched guide. For example, if the user touches the symbol to roll, it can provide a function mapped to the guide, such as "When rolling, the Jenga application is executed." The entire guide may be provided when a preset button is pressed, the flexible display device may be powered on and provided on an initial screen, or may be provided for a while when there is no input on the home screen or application screen for a predetermined time.

In addition, as shown in FIG. 38(c), when bending is completed in the correct position, it may be displayed as "The bending has been performed in the correct bending area." Accordingly, the user can easily know that the bending has been completed. If the bending is not completed in the correct position, “The bending area is incorrect. Bend again.” can be displayed. Accordingly, the user can perform bending again. Here, as shown in FIGS. 38 and 39, the feedback effect may be provided to the user in the form of a text description. However, the feedback effect is not limited to the above, and may be provided in various shapes that can notify the user such as vibration, sound, and warning display.

#2: second embodiment

48 is a block diagram illustrating a flexible display device according to a second exemplary embodiment of the present invention. Referring to FIG. 48, the flexible display device 200 according to the second embodiment of the present invention includes a display unit 210, a sensing unit 220, a control unit 230, a storage unit 240, and an actuator unit 250. Includes all or part. However, in describing FIG. 48, a detailed description of the previously described configuration will be omitted.

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

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

In particular, when the user's gesture for shape transformation of the flexible display device 200 is detected through the sensing unit 220 while the display unit 210 is displaying the application icon, the controller 230 responds to the detected gesture. It is determined whether the shape of the corresponding flexible display device 200 is stored in the storage unit 240.

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

In addition, when the user's gesture for shape transformation of the flexible display device 200 is detected through the sensing unit 220 while the display unit 210 is displaying the driven application screen, the 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.

If the shape is stored, the controller 230 may control to perform a preset 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 shape of the flexible display device 200 corresponding to the performance of the sheet music function of the piano application may be memorized. In this case, while the display unit 210 is displaying the piano application driving screen, the user may deform the flexible display apparatus 200 by bending the upper region in the horizontal direction. Accordingly, the control unit 230 may control to display a sheet music function corresponding to the immediately deformed shape in the upper region.

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

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

In addition, it is determined whether the shape of the flexible display device corresponding to the gesture sensed in the application icon display state is a pre-stored shape (S2902).
