The sensing unit 110 may sense the first bending operation of the first display device 100. [ According to an embodiment of the present invention, a plurality of bending sensors may be provided in or near the first display device 100 to detect the first bending operation. The sensing unit 110 may collect information on the bending operation from the plurality of bending sensors and analyze the bending operation to sense the first bending operation.

The sensing unit 110 can acquire information on the bending position (coordinate value), the bending direction, the bending angle, the bending strength, the bending speed, the number of times of bending, and the timing of occurrence of the bending operation in association with the first bending operation .

For example, the sensing unit 110 can determine the bending position and the bending direction using different characteristics of the pressure of the bent portion and the pressure of the other portion. Also, the sensing unit 110 may calculate an angle, a radius, a number of times, a speed, and the like that are bent based on the amount of change in the force of the bent portion. Meanwhile, the sensing unit 110 may measure the speed at which each part is deformed through the acceleration sensor, and may calculate a bending position and a bending angle by connecting a position having a large change in velocity.

That is, the sensing unit 110 according to an embodiment of the present invention may include a bending sensor, an acceleration sensor, a tilt sensor, a gyro sensor, a 3-axis sensor, A first bending operation can be detected using a magnetic sensor or the like.

The sensing unit 110 may include a first display device 100 and a second display device 100 using a touch sensor, a pressure sensor, a tactile sensor, an illuminance sensor, a proximity sensor, an RF- The display device 200 may collect the sensing data for acquiring information on the arrangement state between the display devices 200. [ Herein, the information on the arrangement state may be information on whether the first display device 100 and the second display device 200 are stacked, or whether the first display device 100 and the second display device 200 are vertically or horizontally And the like.

According to an embodiment of the present invention, the sensing unit 110 may use a touch sensor, a pressure sensor, or the like to acquire information on the arrangement state of the sensing unit (e.g., the screen of the display unit 130) The touch of the second display device 200 can be detected.

Here, when the touch is actually touched by the second display device 200 on the first display device 100, or when the second display device 200 is not actually touched by the first display device 100, Proximity touch "in the case of approaching a predetermined distance from the display device 100. According to an embodiment of the present invention, the sensing unit 110 may acquire information on the placement state It is possible to detect whether a specific object is placed on the sensing surface (for example, the screen of the display unit 130) using the tactile sensor. The tactile sensor may sense the contact of a specific object (e.g., the second display device 200) with a degree of sensitivity or more that the person feels. The tactile sensor can detect various information such as the roughness of the contact surface, the rigidity of the contact object, and the temperature of the contact point.

According to an embodiment of the present invention, in order to acquire information on the arrangement state, the sensing unit 110 may use a proximity sensor to detect a specific object (for example, , The second display device 200) are located close to each other. The proximity sensor can detect the presence or absence of an object approaching or approaching a predetermined detection surface using the force of an electromagnetic field or infrared rays. Examples of proximity sensors 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.

One example of the operation principle of the high frequency oscillation type proximity sensor among the proximity sensors is as follows. When the sensing object approaches the vicinity of the sensor sensing surface in the state of oscillating the high frequency of the stationary wave in the oscillation circuit, the oscillation amplitude of the oscillation circuit is attenuated or stopped And the presence or absence of the sensing object is detected by converting such a change into an electrical signal. Therefore, even if any non-metallic substance comes between the high frequency oscillation proximity sensor and the sensing object, the proximity switch can detect the sensing object to be detected without interference of the object.

For example, the sensing unit 110 may sense proximity or proximity patterns (e.g., proximity distance, proximity direction, proximity speed, proximity time, proximity position, proximity movement state, etc.) To the control unit 140 as information on the arrangement state. The control unit 140 compares the proximity distance between the specific object and the proximity sensor received from the sensing unit 110 with a threshold value for the proximity distance, and when the proximity distance between the specific object and the proximity sensor is smaller than the threshold value, It can be determined that a specific object is located close to the object.

According to an embodiment of the present invention, in order to obtain information on the arrangement state, the sensing unit 110 may use a light intensity sensor to detect a specific object in a sensing direction (for example, a screen direction of the display unit 130) The illuminance sensor can generate various levels of illuminance signals depending on the illuminance of the surroundings (i.e., the intensity of light or the degree of lightness and darkness). For example, the illuminance sensor can sense illuminance of a screen direction of the display unit 130.

According to an embodiment of the present invention, when the second display device 200 is positioned close to the upper portion of the display unit 130 of the first display device 100, the sensing unit 110 may use an illuminance sensor It is possible to transmit the data on the illuminance value, the measurement time, etc. to the control unit 140 by sensing the change in illumination. The control unit 140 compares the illumination value received from the sensing unit 110 with the illumination value received from the second display device 200 to determine whether the second display device 200 is positioned in the screen direction of the display unit 130 Or not.

The sensing unit 110 according to an exemplary embodiment of the present invention may sense a user's selection of at least one content.

The communication unit 120 may include one or more components for communicating with the second display device 200 or the server 300. [ For example, the communication unit 120 may include a mobile communication module 121, a wireless Internet module 123, a wired Internet module 125, a short distance communication module 127, and the like.

 The mobile communication module 121 transmits and receives a radio signal to at least one of a base station, an external terminal, and a server on a mobile communication network. The wireless Internet module 123 is a module for wireless Internet access, and the wireless Internet module 123 may be built in or externally. The wired Internet module 125 is a module for a wired Internet connection.

The short-range communication module 127 is a module for short-range communication. As a local area communication technology, a wireless LAN (Wi-Fi), a Bluetooth, a UWB (Ultra Wideband), a ZigBee, a NFC (Near Field Communication), a WFD Association) may be used.

[ The information on the second bending operation includes information on the bending position (coordinate value), bending direction, bending angle, bending strength, bending speed, number of bending, occurrence timing of bending operation, bending holding time, Information, and the like.

The communication unit 120 may transmit at least one content selected by the user to the second display device 200 via the communication link.

According to one embodiment of the present invention, the communication link that obtains information about the second bending operation and the communication link that transmits the content may be different. For example, the communication unit 120 may acquire information on the second bending operation through the short-range wireless communication (NFC), and may transmit the content through the wireless Internet communication.

The communication unit 120 may transmit the information about the first bending operation, the predetermined content, or the position information of the first display device 100 to the server 300. Also, the communication unit 120 may receive the information about the second display device 200 and the content (shared object) request message from the server 300. [

According to an embodiment of the present invention, the communication unit 120 can transmit and receive content to and from the second display device 200 according to the DLNA (Digital Living Network Alliance) standard. Devices defined in the DLNA (Digital Living Network Alliance) standard include a DMS (Digital Media Server) for providing content, a DMR (Digital Media Renderer) for rendering content, and a content provided by a DMS, And a DMC (Digital Media Controller) that sets up the connection between the DMS and the DMR by matching the rendering capabilities of the DMS and the DMR.

The DLNA specification adopts Universal Plug and Play (UPnP) specification for device discovery and control. UPnP is based on Internet standard technologies such as transmission control protocol / internet protocol (TCP / IP), hypertext transfer protocol (HTTP) and extensible markup language (XML) It is a technology that enables network devices such as home appliances, network printers, and Internet gateways to be networked, in particular, home networking by extending the Plug and Play function to the entire network.

* UPnP network consists of UPnP control device (CD), which is connected to IP based home network, and UPnP control point (CP), to control UPnP control device. The UPnP control device and the UPnP control point communicate with each other using a UPnP protocol stack structure including technologies such as Internet protocols such as TCP / IP and HTTP and technologies such as XML and SOAP (simple object access protocol). The UPnP control point transmits the UPnP control request to the UPnP control device to perform control.

5 is a diagram illustrating a protocol stack of Universal Plug and Play (UPnP) according to an embodiment of the present invention.

The UPnP Vendor 510 is a protocol for extending the function of UPnP. The UPnP Forum 520 provides a Device Control Protocol (DCP). The UPnP Device Architecture 530 is a core of UPnP.

The UPnP control point and the UPnP control device communicate using a control protocol called Simple Object Access Protocol (SOAP, 540).

That is, when the control point discovers a control device connected to the network, and receives a detailed description of the device and the service from the control device, the control device is ready to control the control device. At this time, the control point can control the control device by calling an action that executes a specific service of the control device. Under the UPnP environment, these actions can be expressed in XML (Extensible Markup Language) and transmitted using a communication standard called SOAP (Simple Object Access Protocol).

According to an embodiment of the present invention, the first display device 100 may be a control point and the second display device 200 may be a control device (CD). Conversely, the second display device 200 becomes a control point, and the first display device 100 may be a control device.

6 is a flowchart illustrating DLNA (Digital Living Network Alliance) standards related to an embodiment of the present invention.

In step 61, the DMP (Digital Media Player) can discover the DMS by searching the UPnP devices through the UPnP DA (Device Architecture) step.

At step 62, the DMP requests a description from the discovered DMS and may be provided with a description from the DMS. At this time, the DMP can check the contents list and contents information of the DMS through CDS: Browse / Search (). The content information may include a content ID, a title, a creation date, a type, an access URI, and the like. The DMP can display the received content list to the user through the UI.

In step 63, the DMP can use the PrepareForConnection action of the Connection Manager of the DMS to set the relevant information. The setup message is described in XML, and the setup message may include protocol information configured according to the SOAP format, Connection Manager ID, Connection ID, and information on the delivery direction of the content. The response of the DMS may consist of the ConnectionManager service instance ID, the AV Transport service instance ID, and the RCS service ID.

For example, the PrepareForConnection action tells DMS that the HTTP-GET protocol is used as the transport protocol, the MPEG2-TS format is used as the content format, the ID of the Connection Manager service is 0, and the transfer direction is INPUT.

In step 64, the DMP may notify the DMS of the content to be played back. The DMP can notify the content to be played through the SetAVTransportURI action of the DMS's AV Transport service.

SetAVTransportURI, like PrepareForConnection, is described in XML and configured for the SOAP format. That is, SetAVTransportURI may include a URI of an XML document including a virtual instance ID of an AV Transport service, a URI of the content, and metadata information of the content.

In step 65, the DMP prepares the content for playback using the PrepareForConnection, SetAVTransportURI two actions, and then transmits the Play action to the DMS.

In step 66, the DMP can acquire and play back the content. When the playback method is a push method, the DMS transmits the selected content to the DMP, and the DMP can receive and play the content. When the playback method is a full method, the DMP accesses the DMS to request the content, and the content can be received from the DMS and played back.

4, the display unit 130 may display and output the information processed by the first display device 100. For example, For example, the display unit 130 may display a predetermined content or a content list. When the display unit 130 and the touch pad have a mutual layer structure to constitute a touch screen, the display unit 130 may be used as an input device in addition to the output device.

The display unit 130 may be a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, a three- A 3D display, an electrophoretic display, and a transparent display.

Also, there may be two or more display units 131 according to the embodiment of the first display device 100. [ The touch screen can be configured to detect not only the touch input position, the touch area, but also the pressure of the touch input. In addition, the touch screen can be configured to detect not only a real touch but also a proximity touch.

In the present specification, a pointer may be a tool for touching or touching a specific portion of a displayed screen. For example, the pointer may be an electronic pen, a finger, or the like.

The display unit 130 according to an exemplary embodiment of the present invention may determine whether the first display device 200 is connected to the second display device 200 based on a result of determining whether the first bending operation corresponds to the second bending operation, A confirmation request message for confirming whether or not the communication link is formed can be displayed. Thus, it is possible to prevent a communication link between the first display device 100 and the second display device 200 from being formed or data being shared by the unintended bending operation.

The display unit 130 according to an exemplary embodiment of the present invention may display an image guiding a first bending operation for forming a communication link. The image for guiding the first bending operation may be an image for displaying a bending position (line), a bending direction, a bending angle, a number of times of bending, and the like.

The control unit 140 may form a communication link for transmitting and receiving data to and from the second display device based on the generation time of the first bending operation and the generation time of the second bending operation. According to an embodiment of the present invention, the control unit 140 determines whether or not the pattern information of the first bending operation and the pattern information of the second bending operation match, the difference in distance between the first display device and the second display device, One bending operation and the second bending operation may be further considered to form a communication link.

The controller 140 may control the bending speed of the bending operation based on at least one of a bending position, a bending direction, a bending angle, a bending strength, a bending speed, It is possible to determine whether or not the first bending operation and the second bending operation correspond.

For example, when the difference between the first bending operation and the second bending operation is within a predetermined range, the controller 140 may determine that the first bending operation corresponds to the second bending operation. In addition, when the first bending operation and the second bending operation are symmetrical with respect to a predetermined axis, the controller 140 may determine that the first bending operation and the second bending operation correspond to each other.

In addition, the controller 140 may determine one of the first display device 100 and the second display device 200 as a master device. At this time, based on at least one of a bending position, a bending direction, a bending angle, a bending strength, a bending speed, a bending frequency, and a bending operation occurrence time of the first bending operation and the second bending operation, .

For example, the control unit 140 may determine a display device having a large number of bending operations as a master device, a display device having a quick bending operation occurrence time as a master device, or a display device having a bending direction in a predetermined direction, Alternatively, a display device having a bending angle of a predetermined angle or more may be determined as a master device, or a display device having a bending position at a predetermined position may be determined as a master device. .

Here, the process of determining the master device or the slave device by the control unit 140 may include determining whether the first bending operation and the second operation corresponds to each other, the signal transmission order in the process for forming the communication link, It may be necessary to determine the subject to receive.

However, the process of determining the master device or the slave device by the control unit 140 may be omitted. The first display device 100 and the second display device 200 may not be designed to operate as a master or a slave. Accordingly, when the first display device 100 and the second display device 200 use the same communication protocol or are included in the same network, the first display device 100 and the second display device 200 can be operated without a separate master or slave determination process. The second display device 200 can form a communication link or share content according to the present invention.

The control unit 140 controls the operation of the first display device 100 based on the sensing data (illumination value, proximity pattern, proximity value, etc.) received from the sensing unit 110 of the first display device 100, The arrangement state information between the first display device 100 and the second display device 200 can be obtained by comparing the sensing data (illuminance value, proximity pattern, proximity value, etc.)

For example, it is assumed that the illuminance sensor is present in the screen direction (upper layer) of the display device, and the second display device 200 is laid under the first display device 100. In this case, since the illuminance value sensed by the first display device 100 is greater than the illuminance value sensed by the second display device 200, the controller 140 controls the illuminance of the first display device 100, It is possible to determine that the first display device 100 is positioned on the second display device 200 by comparing the illuminance values of the display device 200. [

The controller 140 controls the operation of the first display device 100 and the second display device 200 based on the third bending operation of the first display device 100 sensed by the sensing unit 110 and the fourth bending operation of the second display device 200 obtained by the communication unit 120 Based on the one, the connection of the formed communication link can be disconnected.

According to an embodiment of the present invention, when the difference between one of the third bending operation and the fourth bending operation and the first bending operation is within a predetermined range, the controller 140 disconnects the formed communication link .

According to another embodiment of the present invention, the control unit 140 may be configured to select one of the third bending operation and the fourth bending operation and to release the connection of the formed communication link when the first bending operation is symmetrical with respect to the predetermined axis can do.

Meanwhile, when the power of the first display device 100 is turned off, the control unit 140 can release the connection of the communication link formed with the second display device 200. [ When the first display device 100 is powered on again, the controller 140 checks the bending state of the second display device 200 to determine whether the first display device 100 and the second display device 200 The communication link may be reconnected. That is, when the first bending operation and the second bending operation are maintained in a state where the first bending operation and the second bending operation are maintained at the time of rebooting the first display device 100, the control unit 140 can reconnect the communication link.

When the distance between the first display device 100 and the second display device 200 is more than a predetermined distance, the control unit 140 controls the second display device 200 and the second display device 200, You can also disconnect. When the distance between the first display device 100 and the second display device 200 approaches a predetermined distance, the controller 140 determines whether the first bending operation and the second bending operation correspond to each other, The communication link between the display device 100 and the second display device 200 may be reconnected. That is, according to an embodiment of the present invention, the first display device 100 may allow the communication link to be maintained only when the second display device 200 is within a predetermined distance from the first display device 100 . Here, the predetermined distance may be a predetermined value indicating the proximity distance of the first display device 100 and the second display device 200. [

Meanwhile, the control unit 140 may maintain the communication link only when the first display device 100 and the second display device 200 are included in the same communication network. For example, when the first display device 100 and the second display device 200 are served by the same WiFi access point, the control unit 140 maintains the communication link, If one of the display devices 200 is moved and serviced by another adjacent access point, it can be controlled so that the communication link is released.

Hereinafter, a method of simply forming a communication link between display devices based on a bending operation will be described with reference to FIG.

7 is a flowchart illustrating a method of forming a communication link according to an embodiment of the present invention.

Referring to FIG. 7, a communication link forming method according to an embodiment of the present invention is comprised of steps that are processed in a time-series manner in the first display device 100 shown in FIG. Therefore, it is understood that the contents described above with respect to the first display device 100 shown in FIG. 4 apply to the communication link forming method of FIG. 7, even if omitted from the following description.

The first display device 100 may sense the first bending operation input by the user (S710). The first display device 100 is a flexible display device that can be bent or rounded, and the user can control the first display device 100 by bending the first display device 100.

The first display device 100 can sense the first bending operation in various ways. An example will be described with reference to FIG.

10 is a diagram illustrating a method of sensing a bending operation in accordance with an embodiment of the present invention.

In step 1010, the first display device 100 according to an embodiment of the present invention can detect bending using various sensors. That is, the sensing unit 100 of the first display device 100 may use the bending sensor to collect data related to the bending operation. For example, the sensing unit 110 of the first display device 100 may use a bending sensor to measure a change in a value or a time of a sensing point where at least one sensing channel included in the bending sensor or the bending sensor is located Can be collected.

For example, as shown in FIG. 10 (a), the bending sensor can sense the bending angle at the sensing point. For example, a bending sensor can sense a bending angle from +180 degrees to -180 degrees. Also, as shown in FIG. 10 (b), a plurality of sensing channels included in a plurality of bending sensors or bending sensors disposed at predetermined intervals can sense a bending angle at each sensing point. Accordingly, the plurality of sensing channels included in the plurality of bending sensors or the bending sensors can be disposed at appropriate positions so as to detect the deformation state of the first display device 100. Data relating to the bending angle collected through the plurality of sensing points can be used to analyze the deformation state of the display plane.

10 (c) is a view showing bending angles at each sensing point collected through a plurality of sensing channels included in a plurality of bending sensors or bending sensors. As shown in FIG. 10 (c), the sensing unit 110 may collect raw data for a bending angle through a plurality of bending sensors or a plurality of sensing channels. For example, the bending angle of the first sensing point collected through the first sensor S1 is '0 degree' and the bending angle of the second sensing point collected through the second sensor S2 is '10 degrees' And the bending angle of the third sensing point collected through the third sensor S3 is '15 degrees'.

In step 1020, the sensing unit 110 may analyze the data related to the collected bending operation to obtain a two-dimensional or three-dimensional coordinate value indicating the deformation state of the display. The sensing unit 110 can analyze the deformation state of the display plane based on the spatial position of each bending sensor. For example, the sensing unit 110 may calculate data representing a deformation state of the display, including a z-axis coordinate value indicating a degree of deformation in the forward or backward direction with respect to the display plane.

10 (d), the sensing unit 110 calculates the three-dimensional coordinate values (x-axis, y-axis, and z-axis) of each sensor point based on the bending angle sensed by each bending sensor Can be derived. For example, the three-dimensional coordinate value of the first sensing point derived from the sensing unit 110 is (10, 4, 2), the three-dimensional coordinate value of the second sensing point is (11, 14, 2) The three-dimensional coordinate value of the sensing point may be (5, 4, 20) or the like. At this time, when the three-dimensional coordinate values of the sensing points are connected, the deformation state of the display plane can be known.

According to one embodiment of the present invention, the controller 140 analyzes the deformation state of the display plane using the sensing data (or information on the arrangement state) received from the sensing unit 110, It can be determined whether or not the bending operation is mapped to the predefined event. 10 (e), the controller 140 analyzes the sensing data (or the information on the arrangement state). As a result, the first bending operation is performed when the first display device 100 bends The first bending operation can be recognized as a flapping operation. When the first display device 100 is maintained in the bending state for a predetermined time or longer, the controller 140 may recognize the first bending operation as bending holding, The first bending operation can be recognized as motion bending when the bending line of the first bending line continuously moves in a predetermined direction.

In addition, the control unit 140 may map the first bending operation to the predefined event and recognize the bending operation in consideration of the position of the sensing point where the bending operation is sensed. For example, if the central portion of the display plane is held in a convex state for a predetermined time or more, the control unit 140 can map the first bending operation to the convexly curved operation of the first display device 100 have

In addition, when the edge of the first display device 100 is bent, the controller 140 may map the first bending operation to the edge bending operation to control the bending motion of the center portion to provide a different event ..

11 is a view of a bending sensor in accordance with an embodiment of the present invention. For example, the bending sensor 1100 may be in a line form. The bending sensor 1100 may include a coil.

The bending sensor 1100 can sense a change in inductance due to a change in current passing through the coil. The bending recognition module 111 can receive the position of the bending sensor in which the inductance has changed, the change value of the inductance, and the like from at least one or more bending sensors.

The sensing unit 110 may derive the bending line based on the position of the at least one bending sensor and derive the bending angle based on the change value of the inductance.

The control unit 140 can recognize the bending operation input by the user as a predefined event based on the derived bending line, the bending angle, and the change value of the inductance.

According to an embodiment of the present invention, the threshold value for determining whether to bend may be changed according to the property of the first display device 100. For example, compared to a display device that is bent even with a relatively small force, a threshold value for determining whether to bend a display device that is bending due to a relatively large force may be low.

According to an embodiment of the present invention, the first display device 100 displays a bending position, a bending direction, a bending angle, a bending strength, a bending speed, a bending frequency, a bending operation occurrence time, Can be detected.

Also, according to an embodiment of the present invention, the first display device 100 may sense a pattern of the first bending operation. For example, when a plurality of bending operations are sequentially performed, the first display device 100 can detect a bending position, a bending order, and a bending pattern.

The first display device 100 may acquire information regarding the second bending operation of the second display device 200 (S720). According to an embodiment of the present invention, the first display device 100 may acquire information on the second bending operation directly from the second display device 200 through wired / wireless communication, 2 < / RTI > bending operation.

The bending direction, the bending angle, the bending strength, the bending speed, the number of times of bending, the time of occurrence of the bending operation, the bending holding time, the bending pattern of the second bending operation according to the embodiment of the present invention, And the like may be included.

The first display device 100 may determine whether the difference between the time of occurrence of the first bending operation and the time of the occurrence of the second bending operation is less than a threshold value [S730]. In addition, the first display device 100 may determine whether the pattern information of the first bending operation and the pattern information of the second bending operation correspond to each other or whether the difference in distance between the first display device 100 and the second display device 200 is a predetermined distance Or less, whether or not the first bending operation and the second bending operation correspond to each other. The first display device 100 according to an exemplary embodiment of the present invention compares the bending position, the bending direction, the bending angle, the bending strength, the bending speed, the bending frequency, and the bending holding time of the first bending operation and the second bending operation Thus, it is possible to determine whether or not the first bending operation and the second bending operation correspond.

For example, when the first bending operation and the second bending operation coincide with each other, or when the first bending operation and the second bending operation are symmetrical with respect to a predetermined axis, the first display device 100 performs the first bending operation and the second bending operation, 2 bending operation corresponds to the bending operation. Meanwhile, the corresponding relationship between the first bending operation and the second bending operation according to an embodiment of the present invention may be predefined.

 The first display device 100 may form a communication link for transmitting and receiving data to and from the second display device 200 based on the time of occurrence of the first bending operation and the time of the occurrence of the second bending operation (S740 ]. That is, the first display device 100 can form a communication link when the difference between the generation time of the first bending operation and the generation time of the second bending operation is less than a preset time. For example, when bending events occur in the first display device 100 and the second display device 200 at substantially the same time (or in a short time lag), the first display device 100 displays the second display device 200, Lt; RTI ID = 0.0 > communication link. ≪ / RTI >

Meanwhile, the first display device 100 may form a communication link for transmitting and receiving data with the second display device 200, taking into consideration the pattern information of the first bending operation and the pattern information of the second bending operation. have. For example, the first bending operation is an operation of bending area A, then bending area B, and then bending area C, and the second bending operation is also an operation of bending area A and then bending area B, The first display device 100 may proceed with a procedure for forming a communication link with the second display device 200. In this case,

According to an embodiment of the present invention, when the first display device 100 determines whether or not to form a link based on the pattern information, the intention of the user can be accurately reflected. Therefore, communication between the first display device 100 and the second display device 200 can be prevented even though the user does not intend to do so. Particularly, when the first display device 100 and the second display device 200 are devices having different shapes, it can be very useful to use the pattern information.

According to an embodiment of the present invention, the first display device 100 can form a communication link, further considering a distance difference from the second display device 200. [

For example, the first display device 100 can form a communication link only when the second display device 200 is within a predetermined distance from the first display device 100. [ Also, the first display device 100 may form a communication link only when the first display device 100 and the second display device 200 are included in the same communication network.

On the other hand, the first display device 100 may form a communication link considering further whether the first bending operation and the second bending operation correspond to each other. That is, when the first bending operation corresponds to the second bending operation, the first display device 100 performs a process for forming a communication link with the second display device 200, 2 bending operation is not supported, the first display device 100 may not perform a process for forming a communication link with the second display device 200. [ On the other hand, when the first bending operation and the second bending operation do not correspond to each other, the first display device 100 may again detect the first bending operation or obtain information on the second bending operation.

According to an embodiment of the present invention, when the first bending operation and the second bending operation correspond to each other, the first display device 100 may display a confirmation request message for establishing a communication link. That is, when the first display device 100 and the second display device 200 perform a similar bending operation at substantially the same time, the first display device 100 forms a communication link from the user (Or data sharing).

As an example of the identification information, there may be a PIN (Personal Identification Number) code.

The pairing between the first display device 100 and the second display device 200 can be performed when the identification information requested by the first display device 100 matches the identification information received from the second display device 200 have.

The generated link key may be stored in the first display device 100 and the second display device 200. Accordingly, the first display device 100 and the second display device 200, which have been paired once, can be interconnected without a pairing process through the link key at the time of subsequent connection. .

According to another embodiment of the present invention, the first display device 100 may form a communication link for the short-range wireless communication (NFC) with the second display device 200.

As shown in Fig. 13 (e), the first bending operation may be a forward folding operation, and the second bending operation may be a backward folding operation. As shown in Fig. 13 (f), the first bending operation may be convex bending operation, and the second bending operation may be concave bending operation. That is, the corresponding bending operations in accordance with an embodiment of the present invention may vary.

In step 815, the first display device 100 may proceed with connection initialization (synchronization) with the second display device 200. Connection initialization (synchronization) means that the timing of exchanging data between the transmitting device and the receiving device is exactly matched. At this time, the first display device 100 may transmit the identification information of the first display device 100 to the second display device 200, and may receive the identification information of the second display device 200.
