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

1 is a block diagram showing the 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, a navigation, and various types of portable devices equipped with a display function, as well as a stationary device such as a monitor, TV, kiosk It might be. According to FIG. 1, the flexible display device 100 includes all or part of the display 110, the sensing unit 120, and the control unit 130. However, before describing FIG. 1, a detailed configuration of the display 110 and a bending detection method therefor will be described in detail.

2 is a view for explaining the basic structure of a display unit constituting a flexible display device according to an embodiment of the present invention. According to FIG. 2, the display 110 includes a substrate 111, a driver 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 rolled like paper while maintaining the display characteristics of an existing flat panel display device. Therefore, the flexible display device must be manufactured on a flexible substrate.

Specifically, the substrate 111 may be embodied 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 base material, it can be implemented with various resins such as polyimide (PI), polycarbonite (PC), polyethyleneterephtalate (PET), polyethersulfone (PES), polythylenenaphthalate (PEN), and fiber reinforced plastic (FRP). 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.

* Meanwhile, in addition to the plastic substrate, the substrate 111 may be made of a material having flexible characteristics, such as a thin glass or a metal foil.

The driving unit 112 functions to drive the display panel 113. Specifically, the driving unit 112 applies a driving voltage to a plurality of pixels constituting the display panel 113, and may be implemented by 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 form of the display panel 113. For example, the display panel 113 may be formed of an organic light emitting body made of 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 pixel cells connected to the transistor. Accordingly, an image may be displayed.

Alternatively, the display panel 113 may be embodied as an EL, an electrophoretic display (EPD), an electrochromic display (ECD), a liquid crystal disply (LCD), an AMLCD, or a plasma display panel (PDP) in addition to the organic light emitting diode. However, in the case of LCD, a separate backlight is required in that it cannot emit light by itself. In the case of an LCD in which no backlight is used, ambient light is used. Therefore, in order to use the LCD display panel 113 without 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, CeO2, and Th O2 may be used for the protective layer 114. The protective layer 114 may be made of a transparent film to cover the entire surface of the display panel 113.

Meanwhile, as illustrated in FIG. 2, the display 110 may be implemented with electronic paper. Electronic paper is a display that applies the characteristics of general ink to paper, and the point of using reflected light is different from a general flat panel display. On the other hand, the electronic paper can use a twist ball or electrophoresis using a capsule to change the picture or text.

On the other hand, when the display 110 is made of a component made of a transparent material, it can be bent and can also be implemented as a display device having transparent properties. For example, when the substrate 111 is made of a polymer material such as plastic having a transparent property, the driving part 112 is made of a transparent transistor, and the display panel 113 is made of a transparent organic light emitting layer and a transparent electrode, the transparency Can have

The transparent transistor refers to a transistor manufactured by replacing the opaque silicon of a conventional thin film transistor with a transparent material such as transparent zinc oxide or titanium oxide. In addition, new materials such as indium tin oxide (ITO) or graphene may be used as the transparent electrode. Graphene refers to a material having transparent properties with a carbon atom connected to each other to form a honeycomb plane. 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 for detecting shape deformation, that is, bending in a flexible display device according to an exemplary embodiment of the present invention It is for drawing.

The flexible display device 100 may be bent by an external pressure to deform its shape. The bending may include the case of normal bending, folding, and rolling. Normal bending refers to a state in which the flexible display device is bent, and the difference from folding and rolling is 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 over a certain radius of curvature, it is defined as a folded state, and when bending is less than the radius of curvature, it can be defined as general bending.

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

However, the definitions of various shape modification examples as described above are only examples, and may be differently defined according to the type, size, weight, and characteristics of the flexible display device. For example, if bending is possible to the extent that the surfaces of the flexible display device 100 can come into contact with each other, folding may be defined as a state in which the surfaces of the devices 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 contact each other due to bending.

For convenience of description, this specification collectively refers to bending of various types and other bending types.

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 surface or a rear surface of the display unit 110, or a bend sensor disposed on both surfaces. The controller 130 may detect bending using a value sensed by the bend sensor of the detector 120.

Here, the bend sensor means a sensor that can be bent by itself and has a characteristic in which a resistance value varies according to the degree of bending. The bend sensor can be implemented as a strain gauge. The strain gauge is a metal or semiconductor whose resistance is greatly changed according to the magnitude of the applied force, and senses the deformation of the surface of the measurement object according to the change in the resistance value. In general, a material such as metal has a characteristic in that the resistance value increases when the length increases according to the force from the outside, and the resistance value decreases when the length decreases. Therefore, when the resistance value change is sensed, it may be determined whether bending is performed.

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 the bending state at the position of the bend sensor according to the magnitude of the resistance value Can detect.

In FIG. 3, the bend sensor shows a state 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 back surface of the display unit 110 or both surfaces. . In addition, the shape, number, and placement of the bend sensor may be variously changed.

FIG. 3 illustrates 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.

According to FIG. 3, the bend sensor includes bend sensors 21-1 to 21-5 arranged in the first direction and bend sensors 22-1 to 22-5 arranged in the second direction perpendicular to the first direction. . Each bend sensor may be spaced apart from each other at regular intervals.

Although FIG. 3 shows that the bend sensors 21-1 to 21-5 and 22-1 to 22-5 are disposed in each of the horizontal and vertical directions, this is only an example, depending on the size of the flexible display device, etc. It goes without saying that the number of bend sensors can be changed. As described above, since the bend sensor is disposed in the horizontal and vertical directions in order to detect bending made in the entire area of the flexible display device, if the device has a flexible characteristic only partially, or if the device needs to detect bending only partially In, a bend sensor may be disposed only in the corresponding portion.

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

Specifically, as shown in FIG. 4, when the center region located at the center of the flexible display device 100 is bent to the downward direction with respect to both left and right edges, bend sensors in which tension due to bending is arranged in the horizontal direction ( 21-1 to 21-5). Accordingly, the resistance value of each bend sensor 21-1 to 21-5 arranged in the horizontal direction is changed. The sensing unit 120 may detect a change in an output value output from each bend sensor 21-1 to 21-5 to detect that bending is performed in a horizontal direction based on the center of the display surface. In FIG. 4, the center region is bent in a vertical direction (hereinafter, referred to as a Z-direction) perpendicular to the display surface, but is vertically upward (hereinafter referred to as a Z + direction) perpendicular to the display surface. Even if it is bent, 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, when the shape of the flexible display device 100 is bent such that the center region located at the center thereof with respect to the upper and lower edges faces upward, as shown in FIG. 5, the bend sensors 22- in which tension is disposed in the vertical direction 1 to 22-5). The sensing unit 120 may sense the 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. In FIG. 5, bending in the Z + direction is illustrated, but 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 the shape deformation in the diagonal direction, the tension is applied to both of the bend sensors arranged in the horizontal and vertical directions, so that the shape deformation in the diagonal direction is also detected based on the output values of the bend sensors arranged in the horizontal and vertical directions. Can be.

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

6 to 8 are diagrams for explaining a method of sensing bending in a flexible display device using a bend sensor in one 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 apparatus 100 is bent, the bend sensors disposed on one or both sides of the flexible display apparatus are also bent together, and have resistance values corresponding to the strength of 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 of the flexible display device 100 is also bent, and the resistance value according to the magnitude of the applied tension is determined. 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 is greatest. Therefore, 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 toward the outside. Accordingly, the bend sensor 31-1 has a smaller resistance value than the point a3 as it goes toward point a2, a1, or point a4, a5 based on point a3.

When the resistance value output from the bend sensor has a maximum value at a specific point and the resistance value output gradually decreases as it goes in both directions, the detector 120 determines that the area where the maximum resistance value is detected is the area where the largest bending is made. can do. In addition, the sensing unit 120 may determine that the area where the resistance value is not changed is a flat area in which bending is not performed, and the area where the resistance value is changed by a predetermined size or more may be determined as a bending area in which bending is slightly performed. .

7 and 8 are diagrams for describing a method of defining a bending area in an embodiment of the present invention. 7 and 8, since the flexible display device is a view for explaining a case in which a flexible display device is bent in a horizontal direction based on a front surface, bend sensors arranged in a vertical direction for convenience of description are not illustrated. In addition, for convenience of description, reference numerals for each bend sensor are differently assigned to each drawing, but bend sensors such as the structure shown in FIG. 3 may be used as it is.

The bending area refers to a curved area in which the flexible display device is bent. Since the bend sensor is bent together by bending, the bending area may be defined as any point where a bend sensor that outputs a resistance value different from the original state is 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 where the resistance value change is sensed.

Specifically, if the distance between the points where the resistance value change is detected is within a predetermined 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 resistance value changes is detected, the distance between them is greater than a predetermined distance, it can be defined by dividing them into different bending areas based on these points. 7 and 8 for a more detailed description.

7 is a view for explaining a method of sensing a single bending area. When the flexible display apparatus 100 is bent as shown in FIG. 7, from a1 to a5 points of the bend sensor 31-1, from b1 to b5 points of the bend sensor 31-2, the bend sensor 31- From point c1 to point c5 of 3), from point d1 to point d5 of bend sensor 31-4, from point e1 to point e5 of bend sensor 31-5, it has a different resistance value from the original state.

In this case, the points where the resistance value change is detected in each bend sensor 31-1 to 31-5 are positioned within a predetermined distance from each other and are continuously arranged.

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

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

In FIG. 8, according to bending of the flexible display device, points a1 to a2 of the bend sensor 31-1 and points a4 to a5, points b1 to b2 of the bend sensor 31-2 and points b4 To point b5, points c1 to c2 of the bend sensor 31-3, and points c4 to c5, points d1 to d2 of the bend sensor 31-4, and points d4 to d5, bend The sensor 31-5 has a different resistance value from the e1 point to the e2 point and from the e4 point to the e5 point.

In the bend sensor 31-1, points a1 to a2 and points a4 to a5 are continuous based on each point, but since points a2 and a4 exist, points a2 to a4 are not continuous. not. Accordingly, when the distances between the points a2 to a4 are spaced apart by a predetermined distance, the points a1 to a2 and points a4 to a5 may be divided into different bending regions. In addition, each point of the other bend sensors 31-2 to 31-5 may also be divided like this.

Therefore, the flexible display apparatus 100 is from the point a1 to the point a2 in the bend sensor 31-1, from the point b1 to the point b2 in the bend sensor 31-2, and from the point c1 in the bend sensor 31-3. The region 34 including all the points from the point d1 to the point d2 in the bend sensor 31-4 and the point e1 through point e2 in the bend sensor 31-5 is defined as one bending area, up to point c2, Bend sensor (31-1) from point a4 to a5, bend sensor (31-2) from point b4 to b5, bend sensor (31-3) from point c4 to c5, bend sensor (31-) The region 35 including all of points e4 to d5 in points 4 to d5 and points e4 to e5 in bend sensor 31-5 may be defined as another bending region.

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, a3 point outputting the largest resistance value in the bending area 33, b3 point outputting the largest resistance value in the bend sensor 31-2, and the largest point in the bend sensor 31-3. Line 33 connecting the c3 point outputting the resistance value, the d3 point outputting the largest resistance value from the bend sensor 31-4, and the e3 point outputting the largest resistance value from the bend sensor 31-5. Can be defined as a bending line. 7 illustrates a state in which a bending line is formed in a vertical direction in a central region 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 point in the bend sensor 31-3. A line connecting the point c1 outputting a large resistance value, a point d1 outputting the largest resistance value from the bend sensor 31-4, and a point e1 outputting the largest resistance value from the bend sensor 31-5. ) Can be one bending line. In addition, the a5 point outputting the largest resistance value in the bending area 35, the b5 point outputting the largest resistance value in the bend sensor 31-2, and the largest resistance value in the bend sensor 31-3 are output. C5 point, d5 point that outputs the largest resistance value from the bend sensor 31-4, and line 36 connecting the point e5, which outputs the largest resistance value from the bend sensor 31-5, 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 describing an example of a method in which a flexible display device detects a folded state.

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

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

For example, when the right edge region of the flexible display apparatus 100 is folded toward the center as shown in FIG. 9, the bend sensor 41-1 disposed on the back side of the flexible display apparatus 100 is also bent and applied 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 strength of the applied tension is greatest, and has a smaller resistance value in both directions. That is, the bend sensor 41-1 has a resistance value smaller than the point a3 as it goes toward point a2, a1, or as point a4, a5 based on point a3.

On the other hand, when folding is performed in which the flexible display device is bent over a certain radius of curvature, the resistance value is sensed at a size equal to or greater than a predetermined size at a point corresponding to the bending line. Accordingly, the control unit 130 may determine whether folding or general bending is performed according to the size of the resistance value.

Alternatively, if bending is possible to the extent that the surfaces of the flexible display apparatus 100 can come into contact with each other, the controller 130 may determine whether folding is performed by considering whether a touch is made. That is, when the right edge of the flexible display device 100 is bent in the Z + direction and folded to the front surface as shown in FIG. 9, areas spaced from each other are in contact with each other on the front surface of the flexible display device 100. In this case, a touch is detected in one area of the display surface, and the degree of change in the resistance value is also greater than in the case of normal bending. Accordingly, the controller 130 calculates the distance from the edge boundary where the bending is made to the bending line, and when a touch is detected at a point spaced apart by the distance calculated in the opposite direction based on the bending line, it is determined that folding is performed. 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 a view for explaining a case where the flexible display device is folded in a horizontal direction based on a front surface, bend sensors arranged in a vertical direction for convenience of description are not illustrated.

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

Referring to FIG. 10, the output resistance value is different from the original state, that is, from point a1 to point a5 in the bend sensor 41-1, from point b1 to point b5 in the bend sensor 41-2, Area including all of points c1 to c5 in the bend sensor 41-3, points d1 to d5 in the bend sensor 41-4, and points 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 outputting the largest resistance value in each folding area. The folding line can be used in the same sense as the bending line.

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

When folding is detected, the controller 130 may perform a different operation from the normal bending operation. For example, an operation such as displaying a different content screen 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 is performed using the result detected by the detection unit 120.

11 to 13 are diagrams for explaining a method in which the flexible display device detects rolling.

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 is applied to a bend sensor disposed on one side 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 to be rolled, bending must be more than a certain curvature. In addition, when rolling is performed, a larger bending area is formed than in the case of normal bending or folding. Accordingly, when it is sensed that bending of a predetermined radius of curvature or more is continuously performed in an area of a predetermined size or more, the controller 130 may determine the rolling state. In addition, in the rolling state, the front and rear surfaces of the flexible display device contact each other. 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 inside the display surface, the display surface, that is, the front surface and the back surface of the bend sensor 50-1 are disposed They come into contact with each other.

Accordingly, in another example as described above, the controller 130 may determine whether the front and rear surfaces of the flexible display device are in a rolling state according to whether they are in contact with each other. In this case, the sensing unit 120 may be provided with a touch sensor. The controller 130 has resistance values output from the bend sensor approximating each other within a predetermined range, and the touch sensors disposed on the front and back sides of the flexible display device When a touch is sensed in each of the fields, it may be determined that the flexible display device is rolled.

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

The rolling area refers to an entire area in which the flexible display device is bent and is in a rolling state. The rolling area may also be defined as one or more areas including all points of the bend sensor that output different resistance values than in the original state as in the case of normal bending and folding. The method of defining and separating the rolling area is the same as that of the bending and folding area, so a duplicate description will be omitted.

As illustrated 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 is circled. When a point outputting a resistance value different from the state is spaced apart 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 device 100 may be bent in various forms, and the controller 130 may sense each bending form based on the detection result of the sensing unit 120. In addition, the control unit 130 may detect how much bending is performed based on the detection result of the sensing unit 120, that is, the bending angle.

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

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

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

In addition, the controller 130 may determine the degree of bending using the calculated resistance value difference. Specifically, the flexible display apparatus 100 may classify the bending degree into a plurality of levels, and match and store resistance values having a predetermined range for each level.

Accordingly, the flexible display device may determine a bending degree of the flexible display device according to a level that belongs among a plurality of levels divided 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 outputting the largest resistance value from the bend sensor 61 provided on the back of the flexible display device 100 and a predetermined distance apart It is possible to determine the degree of bending based on the difference in resistance values output at the point a4.

Specifically, among the plurality of previously stored levels, the level to which the difference in resistance values calculated in the embodiments shown in FIGS. 14 and 15 belongs may be checked, and a bending degree corresponding to the checked 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 larger bending degree than the embodiment shown in FIG. 14, in the embodiment shown in FIG. 15, the resistance value output from the bending sensor a5 point and the resistance value output from the a4 point The difference is greater than the difference between the resistance value output at the point a5 and the resistance value output at the point a4 in the embodiment illustrated in FIG. 14. Accordingly, when bending as illustrated in FIG. 15, the controller 130 may determine that the bending degree is greater.

The controller 130 may perform an appropriate operation according to the bending degree. For example, when the channel zapping operation is performed, if the bending degree 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 in a slower and smaller number of channels. Even during an operation such as volume adjustment or content switching, 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 changed as in the Z + direction or the Z- direction.

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

For convenience of description, FIGS. 16 to 18 will exemplify a case of general bending. However, in the case of folding and rolling, of course, it can be applied as in bending.

According to FIG. 16, two bend sensors 71 and 72 may be provided overlapping each other on one side of the display 110. 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 differently detected 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 illustrated in FIG. 17, a greater intensity tension is applied to the lower bend sensor 72 than the upper bend sensor 71 at point A corresponding to the bending line. Lose.

On the contrary, when the flexible display device 100 is bent in the rear direction as illustrated in FIG. 18, tension of a greater intensity is applied from the upper bend sensor 71 to the lower bend sensor 72.

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

In FIGS. 16 to 18, two bend sensors are shown overlapping 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 110.

Accordingly, when the flexible display apparatus 100 is bent in a first direction (hereinafter, Z + direction) perpendicular to the screen, a bend sensor disposed on the first side of 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 a second direction (hereinafter, referred to as a Z-direction) opposite to the first direction, the bend sensor disposed on the second surface receives a compressive force, while the bend sensor disposed on the first surface receives tension. Will receive. As described above, 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 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 using only a strain gauge disposed on one surface of the display 110. That is, since the strain gauge disposed on one surface is applied with a compressive force or a tensile force according to the 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 a bending sensor is sensed by arranging one bend sensor on one surface of the display 110. According to FIG. 20, the bend sensor 71 may be implemented in a closed curve shape forming a circular or square or other polygonal shape, and may be disposed at the edge of the display 110. The controller 130 may determine a point at which an output value change is detected on the closed curve as a bending area. In addition, the bend sensor may be combined with the display 110 in the form of an open curve such as an S-shape or a zigzag 'Z'.

21 shows an embodiment in which two bend sensors are arranged to cross each other. According to FIG. 21, the first bend sensor 71 is disposed on the first surface of the display 110, and the second bend sensor 72 is disposed on the second surface of the display 110. The first bend sensor 71 is disposed on the first surface of the display 110 in a first diagonal direction, and the second bend sensor 72 is disposed on the second surface in a second diagonal direction. Accordingly, the first and second bend sensors 71 and 72 may be provided for various bending conditions, such as when each edge area is bent, when each edge area is bent, when the central part is bent, when folding or rolling is performed. Since the output value and the output point are different, the controller 130 can determine what type of bending is performed according to the characteristics of the output value.

* Meanwhile, in the various embodiments described above, a case where line-type bend sensors are used is illustrated, but bending may be detected using a plurality of fragmentary strain gauges.

22 and 23 are views showing an embodiment of detecting bending using a plurality of strain gauges.

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

In the state in which the strain gauges are arranged as shown in FIG. 22, the user can bend any point in any direction. Specifically, when one edge 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 arranged in the horizontal direction. Accordingly, the output value of the strain gauge 80-x is greater than the output values of other strain gauges. In addition, among the strain gauges 80-n, 80-n + 1, ~~ 80-m arranged in the vertical direction, a force acts on the strain gauge 80-y overlapping the bending line, thereby changing the output value. The controller 130 may determine that the line connecting the two strain gauges 80-x and 80-y whose output value has changed is a bending line.

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

24 and 25 are views for explaining a method of sensing a bending direction using an acceleration sensor as an example of these 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 the direction of acceleration when 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 sensors are attached. Accordingly, when the acceleration sensors 81-1 and 81-2 are disposed on both edge areas 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, respectively. This is changing. The control unit 130 calculates a pitch angle and a roll angle using output values sensed by the respective 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 detected by the respective acceleration sensors 81-1 and 81-2.

On the other hand, in FIG. 24, the flexible display device 100 shows the state in which the acceleration sensors 81-1 and 81-2 are disposed on both edges in the horizontal direction based on the front surface, but in the vertical direction as in FIG. It may be deployed. In this case, when the flexible display device 100 is bent in the vertical direction, the bending direction may be sensed according to the measurement values detected by the respective acceleration sensors 81-3 and 81-4 in the vertical direction.

24 and 25 illustrate the state in which the acceleration sensors are disposed on the left and right edges or the upper and lower edges of the flexible display device 100, but the acceleration sensors may be disposed on both the upper, lower, left, and right edges, or may be disposed in the corner area. .

As described above, a bending direction may be detected using a gyro sensor or a geomagnetic sensor in addition to the acceleration sensor. The gyro sensor is a sensor that detects an angular velocity by measuring the force of Coriolis acting in the direction of the velocity when a rotational movement occurs. According to the measurement value of the gyro sensor, it is possible to detect in which direction it is rotated, so it is possible to detect the bending direction. The geomagnetic sensor is a sensor that senses azimuth using a 2-axis or 3-axis fluxgate. When implemented as a geomagnetic sensor, the geomagnetic sensor disposed at each edge portion of the flexible display apparatus 100 is moved when the edge portion is bent, and outputs an electrical signal corresponding to the resulting geomagnetic change. The control unit 130 may calculate a yaw angle using a value output from the geomagnetic sensor. Accordingly, various bending characteristics such as a bending area and a bending direction may be determined according to the calculated yaw angle change.

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

Meanwhile, the sensing unit 120 may also detect an operation in which the user touches the screen of the display unit 110 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 thereon. Accordingly, when the user touches the screen, the upper and lower plates of the touched point are touched and an electrical signal is transmitted to the controller 130. The controller 130 recognizes the touch point 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 description is 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 by using a detailed configuration of the display 110 and a bending detection method therefor.

# 1: first embodiment

The display 110 displays a screen. Specifically, the display 110 may display at least one application icon. Also, the display 110 may display an application driving screen. Also, the display 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 110 may provide a guide for at least one bending gesture for performing a preset function of the driven application. Here, in that folding and rolling are performed only when bending is performed, in describing various embodiments of the present invention, the bending gesture will be defined as a concept including both a folding gesture and a rolling gesture.

The sensing unit 120 may detect a bending gesture for bending the flexible display device 100. Here, the sensing unit 120 may be implemented with various types of bend sensors, and the arrangement and detection methods of the bend sensors have been described above, and detailed descriptions 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 110 and the sensing unit 120.

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

Specifically, the controller 130 may determine whether bending of the flexible display apparatus 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 the Jenga game application, the flexible display device 100 must be transformed into a rectangular pillar shape. Therefore, the control unit 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, and the guide for making the flexible display device 100 into a square column shape. Can provide.

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

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

In addition, if it is determined that bending of the flexible display apparatus 100 is not necessary, the controller 130 may 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 deformed in order to drive an SNS application. In this case, the controller 130 does not provide a separate guide and can drive the selected SNS application.

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

Specifically, the control unit 130 may determine whether bending of the flexible display device is necessary 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 the piano keys on the driving screen. However, in order for the driven piano application to provide a sheet music screen, a region 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 bending gesture of the user for bending of the flexible display device is sensed through the detector 120 and the detected gesture is determined as a preset gesture for the driven application, the controller 130 is configured to function as the driven application. It can be controlled to be performed. If the above-described piano application is described as an example, the controller 130 may be a display unit 110 if the shape of the flexible display device 100 modified according to a user's gesture is a preset shape for providing a score function in a driven piano application. ) Can provide a score function in one area.

In addition, the controller 130 detects a plurality of bending gestures of a user for bending the flexible display device 100 through the sensing unit 120, and the flexible display device 100 uses the detected plurality of bending gestures. If it is determined that the deformation has been made to the set shape, the driven application may be controlled to be performed with a preset function. That is, if the above-described piano application is described as an example, the user can repeat the bending gesture in the provided guide. However, even in this case, if the shape of the flexible display apparatus 100 modified according to the bending gesture of the user is a preset shape for providing a sheet music function in a driven piano application, the control unit 130 may In addition, a score function may be provided to the area. In addition, the controller 130 performs different operations according to the number of bendings, such as 1, 2, 3 times, etc., detected through the sensing unit 120. 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, and application switching may be performed when bending is performed three times. Alternatively, the controller 130 may perform the same function when the shapes of the flexible display device 100 modified by bending gestures such as 1, 2, 3 times, or the like are 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 bending according to the first guide provided and then bending according to the second guide provided. Also, 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 apparatus 100 modified by the bending gesture is the same, the controller 130 performs the first function in the case of a sequential bending gesture and performs the second function in the case of the simultaneous bending gesture. Can be. Alternatively, the controller 130 may perform the same function when the shape of the flexible display device 100 modified by the bending gesture is the same without distinguishing 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 the user to view the optimized screen. In this case, the control unit 130 may provide a guide using the 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 interaction with a 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 that 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 GRIP that is easy for a user to use according to the type of content.

In addition, when the NOTIFICATION, RSS, etc. comes, the control unit 130 may provide a guide to be immediately executed. For example, when a text comes from the other party, the control unit 130 may provide a guide for immediately checking the text.

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

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

Here, the comparison result may be to feedback 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, failure of the bending gesture, and completion of the bending gesture. Here, the feedback may be any method that provides accuracy of a bending gesture to the 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 may provide vibration feedback to the user (where vibration feedback is vibration feedback only in an area to be bent, or vibration feedback in the whole). ), Or 'Bending area is wrong', or a text-shaped pop-up window. In addition, if it is determined that the detected bending gesture is a preset gesture, the controller 130 may provide the user with vibration feedback, or a sound such as “The bending area is correct.” Or a text-shaped pop-up window. In this case, the control unit 130 may provide a guide that induces a correct bending gesture again.

In addition, when it is determined that the detected detected bending gesture is a preset gesture, and accordingly the corresponding operation is performed, it is possible to indicate that the operation is performed according to the bending gesture by not displaying the provided guide.

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

In addition, the guides here include guides for bending / folding lines, guides for bending / folding directions, guides for rolling, guides through haptic feedback, and shape deformation and It may be provided in the form of at least one of the related manual guide. In addition, when the flexible display device 100 is provided with an actuator unit, the guide may be a guide guiding the bending operation in a position where bending is to be performed.

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

For example, the bending area may be black and the folding line may be 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 the opposite direction to the user. Alternatively, the black line may be mapped to a bending area corresponding to a 60-degree bending gesture, and the red line may be mapped to a bending area corresponding to a 30-degree bending gesture. However, the present invention 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 on (that is, light without flickering), and the folding line may be mapped to light that is on / off repeatedly (that is, flickering light).

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

In addition, a guide for displaying rolling may be displayed with various symbols. For example, it can be displayed with arrows, text, lines, etc. indicating the rolling operation.

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

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

Here, the guide may indicate a motion 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, it is possible to indicate the number of times the bending should be repeatedly performed in the guide, such as 1, 2, and 3.

The guide also includes FLAP gestures (bending / folding / rolling gestures and gestures that come back in place), HOLD gestures (gestures for making and maintaining bending / folding / rolling gestures), and MOVE gestures (bending / folding / rolling gestures). It may indicate that a gesture to move the bending line in a certain direction. For example, in the case of the driven e-book application, in order to switch to the next page, it is necessary to perform a FLAP gesture in a right corner portion, and thus it is possible to provide that a FLAP gesture must be performed together with a guide. In addition, in the case of the Jenga game application, in order to perform the Jenga application, it is necessary to perform a HOLD gesture to create a rectangular pillar shape, and thus, it is possible to provide that a HOLD gesture must be performed with a guide. However, the present invention 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.

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 the correct guide position. Therefore, the guide may be set including 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 that the application is a preset gesture.

In addition, when the flexible display apparatus 100 is switched to the standby state, and the display 110 displays a standby screen including an icon of the application, the controller 130 displays at least one bending gesture related to a function executable in the standby state. Can provide a guide for Accordingly, when the bending gesture corresponding to the provided guide is made, the controller 130 may perform an operation corresponding to the bending gesture.

Can provide. Accordingly, when the 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 specifically illustrating 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, detailed description of the previously described configuration will be omitted.

The actuator unit 140 manipulates bending of the flexible display device 100. Specifically, the flexible display device 100 may be automatically bent, or a bent shape may be maintained. In addition, the flexible display device 100 may be automatically bent for driving an application or performing a specific function of the driven application. In addition, when the flexible display apparatus 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 disposed in a predetermined area of the flexible display device 100.

When the actuator unit 140 is a plurality of polymer-based materials, as shown in FIG. 49 (a), in order to manipulate shape deformation of the flexible display device 100, the control unit 130 may be configured for a plurality of polymer-based materials. By adjusting at least one of the order of applying the voltage and the magnitude of the applied voltage, it can be controlled to deform to a predetermined shape. That is, in the polymer-based material, the upper portion may contract and the lower portion may be stretched, as shown in FIG. 49 (a), according to at least one of the voltage application order and the magnitude of the applied voltage.

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 flexible display device 100 to a predetermined shape by changing the tensile force of the string. It can be controlled as much as possible. Accordingly, the flexible display device 100 may be automatically deformed, and can also maintain the deformed shape.

That is, when the shape is deformed by applying a physical force to the flexible display device 100, the flexible display device 100 receives a reverse force to return to the original flat shape. In this case, the actuator unit 140 provides the physical force corresponding to the reverse force under the control of the control unit 130 described above, so that the flexible display device 100 maintains the 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 150 may map and store a bending gesture for driving an application corresponding to the selected application icon to each application. Also, the storage unit 150 may map and store a bending gesture for each application to perform the driven application with a predetermined function.

In particular, the control unit 330 may control the actuator unit 350 such that the shape is changed to a required input device shape according to the driven application. For example, when the driven application is an airplane game and the required input device shape is a joystick shape, the controller 330 may control the actuator unit 350 such that the flexible display device 300 is rolled. Alternatively, when the driven application is a golf game and the required input device shape is a golf club shape, the controller 330 may control the actuator unit 350 such that the flexible display device 300 is rolled.

That is, when the gripping area and the touch area are detected through the sensing unit 320, the control unit 330 determines whether the gripping is the right hand or the left hand, determines the touch area, and changes the shape to the area most suitable for the user's use. The display unit 310 may be controlled to provide a corresponding UI.

In addition, when the shape deformation of the flexible display device 300 is performed, the control unit 330 uses the tilt and posture calculated using at least one of an accelerometer and a gyroscope to operate the flexible display device 300 as an input device.
