In one embodiment, the flexible display device 200 can be a stretchable display device that stretches when stretched, and can be reduced back to its original state when released. The stretchable display device can be stretched when stretched, and can be fixed in a stretched state after a certain period of time in a stretched state. Further, the elastic display device can be reduced to its original state when a force for reducing it is applied.

Referring to FIG. 1A, the flexible display device 200 may include a sensing unit 210, a display unit 250, a storage unit 270, and a control unit 290.

The sensing unit 210 can sense the intensity of the force applied to the display unit 250 and the direction of the force.

In one embodiment, the sensing portion 210 may include one or more pressure sensors. One or more pressure sensors may be disposed in the display portion 250. When the sensing unit 210 includes one or more pressure sensors, each pressure sensor 211 is configured to detect a change in capacitance or a change in resistance between both ends of a region to which a pressure (force) is applied, Can be detected. The pressure sensor 211 may transmit at least one of a capacitance change signal indicating a change in the detected capacitance or a resistance change signal indicating a change in resistance to the control unit 290. The capacitance change signal or the resistance change signal may include information on at least one of the strength of the force applied to the pressure sensor 211 and the direction of the force. The control unit 290 can obtain at least one of the direction and the strength of the force applied to the display unit 250 using the capacitance change signal or the resistance change signal received from the pressure sensor 211. [

In another embodiment, the sensing unit 210 may include a plurality of acceleration sensors 213-1 to 213-4, as shown in FIG. 1C. Each acceleration sensor may be disposed adjacent to each vertex of the rectangle when the display unit 250 has a rectangular shape. When the display unit 250 includes a flexible substrate and an image display unit to be described later, the plurality of acceleration sensors 213-1 to 213-4 are disposed at the lower end of the flexible substrate, and the image display unit is disposed at the upper end of the flexible substrate However, this is merely an example, and can be embedded in a flexible substrate or a video display unit.

The acceleration sensor is a sensor that detects acceleration or impact strength when an object moves. By using the acceleration sensor, the motion state of the display unit 250 can be detected in detail. The acceleration sensor can sense the acceleration of the display unit 250 in three directions (x-axis, y-axis, z-axis) perpendicular to each other. The controller 290 can acquire the moving speed using the accelerations in the three axial directions measured through the acceleration sensor. The control unit 290 can obtain the extended distance of the display unit 250 in the three-axis direction using the obtained moving speed. The controller 290 can obtain the direction and force of the force applied to the display unit 250 using the movement speed and the movement distance obtained using the acceleration sensor. The control unit 290 may expand the display unit 250 according to the direction and force of the obtained force.

In another embodiment, the sensing unit 210 may include a plurality of Hall sensors. The plurality of hall sensors may be disposed inside the display unit 250 or on the display unit 250. When the sensing unit 210 includes a plurality of hall sensors, the controller 290 may expand or reduce the display unit 250 through a voltage sensed by the hall sensor according to a force applied to the display unit 250 .

The display unit 250 may be expanded or contracted in at least one direction. The display unit 250 may include a flexible substrate and an image display unit. The flexible substrate can be made of PDMS (polydimethylsiloxane) material with good stretchability and can be expanded according to the pulling force. The image display unit is formed on the flexible substrate and can be expanded together as the flexible substrate is expanded. The image display unit can display an image.

The display unit 250 may include an organic light emitting diode (OLED).

The storage unit 270 may store the magnitude of the magnitude or the degree of reduction of the display unit 250 corresponding to the magnitude of the force and the magnitude of the force applied to the display unit 250, respectively. The degree of expansion of the display unit 250 may indicate the length of the display unit 250 and the degree of reduction of the display unit 250 may indicate the length of the display unit 250.

The control unit 290 may expand or reduce the display unit 250 according to the force sensed through the sensing unit 210. The enlargement of the display unit 250 may indicate that the size of the screen that can be displayed by the display unit 250 is enlarged and the size of the screen that the display unit 250 can display Can be shown to be reduced. The control unit 290 may change a graphic or an image displayed on the screen as the screen size of the display unit 250 is enlarged or reduced.

In addition, the controller 290 can control the operation of the flexible display device 200 as a whole. More specific operations of the control unit 290 will be described later in the following drawings.

2A and 2B are diagrams for explaining an example of use of a stretchable display device which is an example of a flexible display device.

2A shows a display unit 250_1 in a state before the stretchable display unit 200_1 is expanded and contracted. In this state, when a force is applied to the display unit 250_1 in the + x axis direction, the controller 290 enlarges the display unit 250_1 by an extension distance d1 in the + x axis direction as shown in FIG. 2B . As the display unit 250 is expanded, the display unit 250 can be extended by the extended area 251_1 corresponding to the extended distance d1. That is, the screen size of the display unit 250 can be enlarged by the extended area 251_1. In FIG. 2, only the force applied in the + x axis direction is described as an example, but this is merely an example. Conversely, when a force is applied to the display unit 250_1 in the? X axis direction, the controller 290 can return the display unit 250_1 to its original size.

3A to 3F are views for explaining the configuration and operation principle of a roller-barrel display device which is an example of a flexible display device according to an embodiment of the present invention.

FIG. 3A is a perspective view of a roller-type display device according to an embodiment of the present invention, FIG. 3B is a view showing a roller-type display device in a first operation state according to an embodiment of the present invention, 3A is a cross-sectional view of the roller-type display device taken along the line A1-A2 in FIG. 3A, and FIGS. 3E and 3F are cross-sectional views of the rollable display device according to one embodiment of the present invention. FIG. 5 is a view illustrating a process of sensing a length of the display unit, a coiled length, and a rotation amount of the display unit using a Hall sensor according to an embodiment of the present invention.

3A to 3D, the roller-type display device 200-2 includes an upper case 240, an intermediate case 220, a lower case 260, a display unit 250, a first holder 223, And a second holder 223.

The upper case 240, the lower case 260, and the intermediate case 220 form an appearance of the rollerable display device 200_2. The intermediate case 220 may have a cylindrical shape, but is not limited thereto, and may have various shapes such as a hexahedron shape. As shown in FIG. 3D, the intermediate case 220 is partly opened, and a part of the display unit 250 may be exposed to the outside.

The upper case 240 and the lower case 260 may have a structure for covering the middle case 220 from above and below. The upper case 240 and the lower case 260 may not expose various components provided inside the intermediate case 220 to the outside. The upper case 240 may be formed with a recessed portion 246 recessed toward the inside of the upper case 240 so as to be formed in a plane. At least one of the camera 241 and the sound output unit 242 may be formed in the recessed portion 246. [ The first holder 223 (shown in FIG. 3D) may be provided at one end of the display unit 250 and the second holder 224 may be provided at the other end of the display unit 250. The first holder 223 can prevent the display unit 250 from being detached from the inner side of the intermediate case 220 when the screen of the display unit 250 is maximally expanded. The second holder 224 can prevent the display unit 250 from being rolled inside the intermediate case 220. The user can extend the screen of the display unit 250 by pulling the second holder 224 in a specific direction.

The display portion 250 may roll-in or roll-out outside the intermediate case 220. [0030] That is, the display unit 250 may be wound (wind, roll, coil) in the middle case 220 or may be unwinded, unrolled, or uncoiled to the outside of the intermediate case 220.

FIG. 3B is a view showing that the rolled-type display device 200-2 is in a first operation state, and FIG. 3C is a view showing being in a second operation state.

In a state in which the display unit 250 is not deformed (for example, a state having an infinite radius of curvature, hereinafter referred to as a first operating state), the area displayed by the display unit 250 may be a flat surface. The area displayed by the display unit 250 in a state deformed by an external force in a first operating state (e.g., a state having a finite radius of curvature, hereinafter referred to as a second operating state) may be a curved surface. As shown in the figure, the information displayed in the second operating state may be time information output on the curved surface. Such visual information can be realized by independently controlling the emission of a sub-pixel arranged in a matrix form.

The display portion 250 may be placed in a bent state (e.g., a state in which the display portion 250 is bent upwardly or downwardly or laterally) instead of a flat state in the first operation state. In this case, if an external force is applied to the display unit 250, the display unit 250 may be deformed into a flat state (or a less bent state) or a more bent state.

Meanwhile, the display unit 250 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made to the flexible touch screen, the control unit 290 can perform control corresponding to the touch input. The flexible touch screen can sense the touch input not only in the first operating state but also in the second operating state.

Meanwhile, the roller-type display device 200-2 according to the embodiment of the present invention may be provided with a deformation detection means for detecting a deformation of the display unit 250. [ The deformation detecting means may be included in the sensing unit 210 (see FIG. 1A).

The deformation detecting means may be provided in the display unit 250 or the intermediate case 220 to sense information related to the deformation of the display unit 250. Here, the information related to the deformation may be the direction in which the display unit 250 is deformed, the degree of deformation, the deformation position, the deformation time, and the acceleration at which the deformed display unit 250 is restored. And may be various information that can be detected due to warping of the display unit 250.

The control unit 290 may change the information displayed on the display unit 250 or change the information displayed on the display unit 250 based on the information related to the deformation of the display unit 250, 2 can be generated.

In one embodiment of the present invention, the first operation state of the roller-type display device 200-2 is a state in which only a minimum display area is exposed to the outside so as to display only basic information in a disabled state. The second operating state of the rollerbble display device 200-2 means that the display unit 250 is in an expanded state. The expanded display unit 250 may mean that the screen displayed by the display unit 250 is expanded. The expansion at this time includes a gradual expansion. The display area of the roller-type display device 200-2 may be expanded or reduced by rolling the display part 250. However, the display area of the roller-type display device 200-2 may be expanded or reduced gradually . Therefore, in the following description, all states other than the first operating state can be referred to as a second operating state, and the second operating state can be divided into a plurality of steps according to the degree of expansion.

3B, only the areas such as the message window 225, the icon 226, and the time display unit 227 are displayed in the first operation state, thereby minimizing the exposure area of the display unit 250. [ However, in the second operation state, as shown in FIG. 3C, the exposure area of the display unit 250 can be maximized to display information on a larger screen. In some cases, it is assumed that FIG. 3C shows a state in which the display unit 250 is maximally expanded.

The control unit 290 (shown in FIG. 1A) can sense the length of the display unit 250 and can turn on or off part of the display unit 250 based on the length. For example, the control unit 290 may obtain the length of the display unit 250 that is wired outside the open area of the intermediate case 220. The control unit 290 can turn off the display unit 250 disposed inside the intermediate case 220 and turn on the display unit 250 worn out from the open area of the intermediate case 220. [ When a part of the display unit 250 is turned on, it means that a part of the display unit 250 is powered to display information. When a part of the display unit 250 is turned off, It may mean that the power is not applied. Accordingly, a part of the display unit 250 which is not wound to the outside of the intermediate case 220 is turned off, so that unnecessary power consumption and heat generation can be prevented.

When the display unit 250 is separated from the outer circumferential surface of the inner case 238, the control unit 290 can turn on the separated part and turn off the not-separated part. The control unit 290 can recognize that the display unit 250 is separated from the outer circumferential surface of the inner case 238 by using the length sensing unit 211 disposed on the inner circumferential surface of the inner case 238, And the non-separated portion can be turned off.

3C, a shaft 281, an inner case 238, a length sensing portion 211, a rotation amount sensing portion 213, a plurality of circuit boards 280, A circuit board 283, and a support frame 262 may be formed.

The shaft 281 can be rotated in accordance with the rotation of the inner case 238.

The inner case 238 can be configured in the form of a roller, is rotatable, and can perform a function of winding or winding the display unit 250 according to the rotation. The inner case 238 is axially connected to the intermediate case 220 and is rotatable.

The length sensing unit 211 may sense the length of the display unit 250 wound or the length of the tape wound. The length sensing portion 211 may be constituted by a magnetic member. The length sensing portion 211 may include at least one Hall sensor. The length sensing unit 211 will be described later in detail.

The rotation amount sensing unit 213 can sense the number of times the display unit 250 is wound on the inner case 238. [ That is, the rotation amount sensing unit 213 can sense how many times the display unit 250 is wound as the display unit 250 is curled on the inner case 238. The rotation amount sensing unit 213 may be constituted by a magnetic member. The rotation amount sensing unit 213 may include at least one Hall sensor. This will be described in detail later.

Each of the plurality of circuit boards 280 can mount a plurality of electronic circuit components for operation of the rollerable display device 200-2.

The flexible circuit board 283 may connect the display unit 250 with the electronic circuit components mounted on the inner case 238. The electronic circuit component may include one or more of the sensing unit 210, the storage unit 270, and the control unit 290 shown in FIG. 1A.

The support frame 262 supports the circuit board 280 and may be provided inside the inner case 238.

The inner case 238 can be rotated by the magnetic force between the length sensing part 211 and the rolling sensing part 234 formed apart from the lower part of the display part 250. The rolling sensing portion 234 may also be composed of a magnetic member and may include one or more Hall sensors. The display unit 250 may be rotated together with the inner case 238 while being dried on the inner case 238 by the magnetic force. Specifically, the display unit 250 may be rolled by an attractive force between the rolling sensing unit 234 and the length sensing unit 211. For example, when the length sensing portion 211 is constituted by a magnetic member of N pole and the rolling sensing portion 234 is constituted by magnetic members of S pole, they are attracted to each other by attraction of each other. The length sensing portion 211 may be fixed in position. The rolling sensing part 234 is drawn while being linearly moved toward the length sensing part 211 and the continuously formed rolling sensing part 234 is continuously introduced into the intermediate case 220. [ The rolling sensing unit 234 that has already been introduced is continuously operated with the length sensing unit 211 so that the rolling sensing unit 234 and the length sensing unit 211 are balanced with the attractive force between the newly introduced rolling sensing unit 234 and the length sensing unit 211, 234 are rotated about the length sensing portion 211. By such a mechanism, the display unit 250 is rolled and rolled.

A sheet 222 having a rolling sensing unit 234 may be provided on a lower surface of the display unit 250. The sheet 222 may be included in the display unit 250 or may be separate from the display unit 250. The sheet 222 may have a flexible material. For example, the sheet 222 may be silicone or thermoplastic polyurethane (TPU). The sheet 222 is attached to the lower surface of the display unit 250 in the form of a sheet frame and the sheet 222 sequentially fixes the rolling sensing unit 234, tape or insert molding. Further, the sheet 222 should have a flexible property while maintaining a thin thickness, and a material having excellent elasticity and elongation can be used. This is to allow the rolling sensing parts 234 to have the same stimulus so that the display part 250 is flattened by the repulsive force. That is, the rolling sensing parts 234 having the same magnetic poles push the rolling sensing part 234 formed by the repulsive force, so that the display part 250 is flatly spread.

The length sensing unit 211 may sense the magnetic force with the rolling sensing unit 234 and calculate the length of the display unit 250 to be wound or the length to be wound. The rotation amount sensing unit 213 may sense the number of times the display unit 250 is wound on the outer circumferential surface of the inner case 238. [ This will be described with reference to Figs. 3E and 3F.

Referring to FIG. 3E, the length sensing unit 211 may include four Hall sensors H1, H2, H3, and H4. The four Hall sensors are spaced apart at regular intervals along the circumferential direction of the inner case 238 in the inner circumferential surface or the inner space of the inner case 238. [ At this time, the first to fourth Hall sensors H1, H2, H3, and H4 detect the movement of the rolling sensing unit 234 by sensing the change in magnetic force in the circumferential direction of the inner case 238 by the rolling sensing unit 234 .

The arrows in Figs. 3E and 3F indicate the rotating direction of the inner case 238. Fig. The first through fourth Hall sensors H1, H2, H3, and H4 can rotate only the first hall sensor H1 in the second operating state in which the display unit 250 is exposed to the maximum as the inner case 238 rotates, Sensing unit 234 is sensed. Thereafter, when the inner case 238 rotates counterclockwise, the display unit 250 is wound on the inner case 238, and the second hall sensor H2, the third hall sensor H3, (H4) senses the rolling sensing unit 234 sequentially. The first through fourth hall sensors H1, H2, H3, and H4 may be provided with information that can measure the length of the display unit 250 that the display unit 250 winds along the outer circumferential surface of the inner case 238 Lt; / RTI > The control unit 290 can grasp the sensor in which the display unit 250 is wound or the rolling sensing unit 234 is sensed last time. Accordingly, the control unit 290 can estimate the length of the display unit 250 that is wound or unwound. This is also true when the display unit 250 is wound a plurality of times on the inner case 238. [

When the display unit 250 is wound in two or more layers on the outer circumferential surface of the inner case 238, the magnetic force in the radial direction of the inner case 238 is changed. Therefore, It is possible to measure the winding length of the wire 250.

For example, as shown in FIG. 3F, when two or more Hall sensors are spaced apart from each other in the radial direction of the inner case 238, a rolling sensing part 234 And the winding length of the display unit 250 can be calculated more accurately. In FIG. 3F, three sensors of the fifth through seventh Hall sensors H5, H6 and H7 are disposed, but this is merely an example. That is, the fifth through seventh Hall sensors H5, H6, and H7 sense the magnetic force change in the radial direction of the inner case 238 by the rolling sensing unit 234.

More specifically, the controller 290 controls the first to fourth Hall sensors (not shown) while the display unit 250 is wound on the inner case 238 as a single layer in the second operating state H1, H2, H3, and H4) can be calculated. The fifth through seventh Hall sensors H5, H6 and H7 sense the magnetic force change in the radial direction when the display unit 250 is wound up in a state of being laminated on the inner case 238 in two layers. The control unit 290 can obtain the number of times the display unit 250 is wound using the magnetic force change sensed through the fifth through seventh Hall sensors H5, H6, and H7. The subsequent winding length can be calculated again by the first through fourth hall sensors H1, H2, H3 and H4, and the radial direction in which the fifth through seventh Hall sensors H5, H6 and H7 are formed When the three layers are stacked, the fifth through seventh Hall sensors H5, H6 and H7 detect the magnetic force change. The control unit 290 can calculate the length of the display unit 250 wound on the outer circumferential surface of the inner case 238 through the first through fourth hall sensors H1, H2, H3 and H4, The number of times that the display unit 250 is wound on the outer circumferential surface of the inner case 283 through the seventh to eighth Hall sensors H5, H6, and H7 can be calculated.

According to another embodiment of the present invention, the rollerable display device 200-2 further includes an upper case 240, an intermediate case 220, and a lower case 260 at the other end of the display unit 250 can do. The interior of the intermediate case 200 may include the components described in FIG. 3D. Accordingly, the user can grip the roller-bar-shaped display device 200-2 with both hands to expand or contract the display portion 250. [

3G to 3H are views showing a roller-type display device according to another embodiment of the present invention.

The roller-type display device 200-2 according to the present embodiment may include a case 295, a holder 224, and an acoustic output section 242. [ Here, the case 295 may include an upper case 240, a lower case 260, and an intermediate case 260.

Meanwhile, the case 295 can receive the first display unit 250. In addition, the case 295 may be provided with a groove button and a second display unit 290.

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

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

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

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

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

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

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

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

Touch can be sensed.

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

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

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.
