The components shown in FIG. 1 are not essential for implementing the mobile terminal, so the mobile terminal described in this specification may have more or fewer components than those listed above.

More specifically, among the components, the wireless communication unit 110 is between the mobile terminal 100 and the wireless communication system, between the mobile terminal 100 and another mobile terminal 100, or between the mobile terminal 100 and an external server. It may include one or more modules that enable wireless communication between them. In addition, the wireless communication unit 110 may include one or more modules for connecting the mobile terminal 100 to one or more networks.

The wireless communication unit 110 may include at least one of a broadcast reception module 111 , a mobile communication module 112 , a wireless Internet module 113 , a short-range communication module 114 , and a location information module 115 . .

The wireless signal may include various types of data according to transmission/reception of a voice call signal, a video call signal, or a text/multimedia message.

The wireless Internet module 113 refers to a module for wireless Internet access, and may be built-in or external to the mobile terminal 100 . The wireless Internet module 113 is configured to transmit and receive wireless signals in a communication network according to wireless Internet technologies.

As wireless Internet technology, for example, WLAN (Wireless LAN), Wi-Fi (Wireless-Fidelity), Wi-Fi (Wireless Fidelity) Direct, DLNA (Digital Living Network Alliance), WiBro (Wireless Broadband), WiMAX (World Interoperability for Microwave Access), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A), etc., and the wireless Internet module ( 113) transmits and receives data according to at least one wireless Internet technology within a range including Internet technologies not listed above.

The short-range communication module 114 is for short-range communication, and is for Bluetooth™ RFID (Radio Frequency Identification), infrared communication (Infrared Data Association; IrDA), UWB (Ultra Wideband), ZigBee, NFC (Near). Field Communication), Wi-Fi (Wireless-Fidelity), Wi-Fi Direct, and at least one of Wireless USB (Wireless Universal Serial Bus) technologies may be used to support short-distance communication. , between the mobile terminal 100 and a wireless communication system, between the mobile terminal 100 and another mobile terminal 100, or between the mobile terminal 100 and another mobile terminal 100, or (external server) may support wireless communication between networks located in. The local area network may be wireless personal area networks.

In particular, as short range communication, NFC (Near Field Communication) is between the mobile terminal 100 and another mobile terminal 100, or between the mobile terminal 100 and the other mobile terminal 100 or an external server. It can support wireless communication between networks. NFC uses a signal of a low frequency band of 13.56 MHz and uses a coil-type antenna because it performs wireless communication in an ultra-short distance of 10 cm or less.

A coil antenna for short-distance communication transmits a signal through a magnetic field by an electric field formed when a current flows through a coil, rather than a method of propagating a signal in the air like an antenna for mobile communication. When the counterpart antenna is positioned within the magnetic field formed by the coil antenna, signals can be transmitted and received. Since the coil antenna occupies a large area, it is generally arranged to be attached to the inner surface of the rear case.

Among them, the NFC module provided in the mobile terminal supports contactless short-range wireless communication between terminals at a distance of about 10 cm. The NFC module may operate in any one of a card mode, a reader mode, and a P2P mode. In order for the NFC module to operate in the card mode, the mobile terminal 100 may further include a security module for storing card information. Here, the security module may be a physical medium such as a Universal Integrated Circuit Card (UICC) (eg, a Subscriber Identification Module (SIM) or a Universal SIM (USIM)), a Secure micro SD, and a sticker, or a logical medium embedded in the mobile terminal ( For example, it may be an embedded secure element (SE). Data exchange based on SWP (Single Wire Protocol) may be performed between the NFC module and the security module.

When the NFC module is operated in card mode, the mobile terminal may transmit stored card information to the outside like a traditional IC card. Specifically, when a mobile terminal storing card information of a payment card such as a credit card or a bus card is brought close to a payment machine, a mobile short-distance payment can be processed, and the mobile terminal storing card information of the access card is approved for access Approaching the flag, the access approval process can begin. Cards such as credit cards, transportation cards, and access cards are loaded in the security module in the form of an applet, and the security module may store card information about the loaded card. Here, the card information of the payment card may be at least one of a card number, balance, and usage history, and the card information of the access card is at least one of a user's name, number (eg, user's student number or company number), and access details. can be one

When the NFC module is operated in the reader mode, the mobile terminal may read data from an external tag. In this case, data received by the mobile terminal from the tag may be coded in a data exchange format determined by the NFC forum. In addition, the NFC forum defines four record types. Specifically, the NFC forum defines four Record Type Definitions (RTDs) such as Smart Poster, Text, Uniform Resource Identifier (URI), and General Control. When the data received from the tag is a smart poster type, the controller executes a browser (eg, an Internet browser), and when the data received from the tag is a text type, the controller executes a text viewer. When the data received from the tag is a URI type, the controller executes a browser or makes a call, and when the data received from the tag is a general control type, an appropriate operation may be executed according to the control content.

When the NFC module operates in a peer-to-peer (P2P) mode, the mobile terminal may perform P2P communication with another mobile terminal. In this case, a Logical Link Control Protocol (LLCP) may be applied to P2P communication. For P2P communication, a connection may be created between a mobile terminal and another mobile terminal. In this case, the generated connection may be divided into a connectionless mode in which one packet is exchanged and terminated, and a connection-oriented mode in which packets are continuously exchanged. Through P2P communication, data such as electronic business cards, contact information, digital photos, URLs, and setup parameters for Bluetooth and Wi-Fi connections may be exchanged. However, since the available distance of NFC communication is short, the P2P mode may be effectively utilized for exchanging small-sized data.

In this way, the display unit may use the flexible display unit 151 that is bent so that the position of the display unit can be changed. The flexible display unit 151 is a display unit that can maintain a flat state like a conventional flat panel display, and can be bent, bent, folded, twisted, or curled like paper. It refers to a durable display that is manufactured on a thin and flexible substrate and is not easily broken. It can be bent in a specific direction like paper, and the flexible display unit of the present invention can be arranged so that the curvature can change in the first direction.

In addition, electronic paper is a display technology to which the characteristics of general ink are applied, and may differ from the conventional flat panel display in that it uses reflected light. Electronic paper can change information by using a twisted ball or by using electrophoresis using a capsule.

In a state in which the flexible display unit 151 is not deformed (eg, a state having an infinite radius of curvature, hereinafter referred to as a basic state), the display area of the flexible display unit 151 becomes a flat surface. In a state deformed by an external force from the basic state (eg, a state having a finite radius of curvature, hereinafter referred to as a deformed state), the display area may be a curved surface. As shown, the information displayed in the deformed state may be visual information output on the curved surface. Such visual information is implemented by independently controlling the emission of sub-pixels arranged in a matrix form. The unit pixel means a minimum unit for realizing one color. When an external force is applied to the flexible display unit 151 , the flexible display unit 151 may be deformed from a flat state to a curved state instead of a flat state.

Meanwhile, the flexible display unit 151 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made to the flexible touch screen, the controller 180 (refer to FIG. 1 ) may perform a control corresponding to the touch input. The flexible touch screen may be configured to sense a touch input not only in the basic state but also in the deformed state.

The touch sensor senses a touch (or touch input) applied to the touch screen using at least one of a variety of touch methods, such as a resistive method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method.

As an example, the touch sensor may be configured to convert a change in pressure applied to a specific part of the touch screen or a change in capacitance occurring in a specific part of the touch screen into an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, an electrostatic capacitance at the time of touch, etc. in which a touch object applying a touch on the touch screen is touched on the touch sensor.

On the other hand, the mobile terminal 100 may be provided with a deformation detection means for detecting the deformation of the flexible display unit 151 . Such deformation detecting means may be included in the sensing unit 140 (refer to FIG. 1).

The deformation detecting means may be provided in the flexible display unit 151 or the case (first and

second frames

101 and 102 to be described later) to detect information related to deformation of the flexible display unit 151 . Here, the information related to the deformation may be a direction in which the flexible display unit 151 is deformed, a deformed degree, a deformed position, a deformed time, and an acceleration at which the deformed flexible display unit 151 is restored. In addition, the flexible display unit 151 may be various types of information detectable due to bending.

In addition, the control unit 180 changes information displayed on the flexible display unit 151 based on the information related to the deformation of the flexible display unit 151 detected by the deformation detecting means, or the mobile terminal 100. It is possible to generate a control signal to control the function of

Also, the deformation of the flexible display unit 151 may vary depending on the positions of the first frame 101 and the second frame 102 . As shown in FIG. 2 , since the bent position of the flexible display unit 151 is determined according to the positions of the first frame and the second frame, the first frame 101 and the second frame instead of the deformation detecting means of the flexible display unit 151 are 2 Depending on the position of the frame 102 , the bending deformation position and the front area of the flexible display unit 151 may be calculated.

The change of the state of the flexible display unit 151 (first or second state), that is, the size change of the display unit 151 in the front and the rear of the mobile terminal 100 according to the size change of the mobile terminal 100, It may be performed manually by a force applied by a user, but is not limited to such a manual method. For example, when the mobile terminal 100 or the flexible display unit 151 has a first state, it may be transformed into a second state by a command from a user or an application without an external force applied by the user. In order to automatically deform the flexible display 151 without external force as described above, the mobile terminal 100 may include a driving unit 200 to be described later.

The flexible display unit 151 of the present invention is bent 180 degrees while wrapping around the side of the mobile terminal 100 in the first direction. Accordingly, a part of the flexible display unit 151 is disposed on the front side of the mobile terminal 100 based on the side of the mobile terminal 100 , and the other part of the flexible display unit 151 is located on the back side of the mobile terminal 100 . are placed For convenience of description, the flexible display unit 151 located at the front is referred to as a front side, and the flexible display unit 151 located at the rear side is referred to as a rear side. As shown in FIG. 2 , the mobile terminal may be expanded in a first direction or contracted in a second direction opposite to the first direction. In this case, the area of the flexible display unit 151 located in the front changes. That is, the sizes of the front part and the rear part may vary according to a change in the state of the mobile terminal.

A part of the flexible display unit 151 located on the front side of the mobile terminal 100 may be fixedly fixed to the front side of the first frame 101 , and the other part of the flexible display unit 151 located on the rear side of the mobile terminal 100 is It may be provided movably on the rear surface.

In addition, the flexible display unit 151 may be wound or unwound from the side of the mobile terminal in the first direction, and accordingly, a portion disposed on the rear surface of the mobile terminal 100 is moved to move the flexible display unit 151 of the flexible display unit 151 . The size of the area disposed in front of the mobile terminal 100 may be adjusted. Since the area of the flexible display unit 151 is fixed and it is composed of one continuous body, when the area of the front portion increases, the area of the rear portion decreases. Such a display unit 151 may be wound in a second frame 102 that is relatively movable to a first frame 101 to be described later, precisely on the side of the second frame 102 in the first direction, In order to adjust the area of the display unit 151 on the front side of the mobile terminal 100 , it is wound around the second frame 102 according to the moving direction of the second frame 102 and withdrawn from the second frame 102 . or pulled out) or inserted into it (insert or pushed into). This operation will be described in more detail below along with other related components of the mobile terminal 100 .

Typically, the antenna is provided in the case or housing of the mobile terminal 100 , but the portion where the antenna is installed in the case or housing is limited by the flexible display unit 151 covering the front and rear surfaces of the mobile terminal 100 . can be For this reason, an antenna may be implemented on the flexible display unit 151 . Antenna on display (AOD) is a type of antenna in which a patterned electrode layer and a dielectric layer are layered to form a transparent film. The built-in display antenna can be implemented thinner than the laser Direct Structuring (LDS) technology implemented by the existing copper nickel plating method, so it has the advantage of not being exposed to the outside with little effect on the thickness. Also, the built-in display antenna may directly transmit/receive a signal from the display unit 151 . Accordingly, in the mobile terminal 100 in which the display unit 151 is positioned on both sides as in the present invention, a built-in display antenna can be used.

4 and 5 are exploded perspective views of a mobile terminal according to an embodiment, wherein FIG. 3 is an exploded perspective view seen from the front direction, and FIG. 5 is an exploded perspective view seen from the rear direction.

The mobile terminal 100 of the present invention includes

frames

101 and 102 on which components are mounted, and the

frames

101 and 102 of the present invention may vary in size in the first direction as shown in FIG. 2 . . At least one or

more frames

101 and 102 may move relatively and have different sizes in the first direction. The

frames

101 and 102 have electronic components mounted therein and the flexible display unit 151 positioned outside.

Since the mobile terminal 100 of the present invention includes the flexible display unit 151 , the flexible display unit 151 can be coupled to cover the front and rear surfaces of the

frames

101 and 102 . The frame may include a first frame 101 and a second frame 102 moving in a first direction with respect to the first frame 101 . The first frame 101 and the second frame 102 include a front portion, a rear portion and a side portion, and are coupled to each other.

First, the first frame 101 corresponds to the main body of the mobile terminal 100 , and a space for accommodating various parts may be formed between the first front part 1011 and the first rear part 1012 . In addition, the first frame 101 may accommodate the second frame 102 movably coupled to the first frame 101 in such a space. In more detail, the first frame 101 is disposed in front of the mobile terminal 100 to support the front portion of the display unit 151 as shown in FIGS. 2 and 5. 1011) and a first rear portion 1012 disposed at the rear of the mobile terminal and on which various components are mounted.

The first front portion 1011 and the first rear portion 1012 may be spaced apart from each other at a predetermined distance to form a predetermined space, and the first side portion (1013) can be connected to each other. The first side portion 1013 may be formed integrally with the first rear portion 1012 or the first front portion 1011 . A camera 121, a sound output unit 152, an input/output terminal 161, a control unit 180, and a power supply unit 190 may be accommodated as parts of the mobile terminal 100 in the space within the first frame 101. . For example, the control unit 180 may be a circuit board 181 including a processor and an electronic circuit for controlling the operation of the mobile terminal, and the power supply unit 190 may be the battery 191 and related parts. . In addition, the driving unit 200 for controlling the sliding movement of the second frame 102 to be described later may be accommodated in the first frame 101 .

As described above, the display unit 151 has a continuous body and may be disposed on both the front and rear surfaces of the mobile terminal 100 while being wound in the mobile terminal 100 . The display unit 151 may include a front portion positioned on the front of the mobile terminal 100 , a rear portion positioned on the rear surface, and a side portion positioned between the front portion and the rear portion and surrounding the side surface of the mobile terminal. The front part and the back part may be flat, and the side part of the display unit 151 may form a curved surface. When the flexible display unit 151 is bent at an angle, the flexible display unit 151 may be damaged, and the side portion may be configured to be bent with a predetermined curvature.

The display unit 151 may be divided into a fixed unit and a variable unit. The fixed part means a part fixed to the frame. Since it is fixed to the frame, it is characterized in that the degree of bending does not change and maintains a constant shape. On the other hand, the variable part means a part in which the angle of the curved part is variable or the position of the curved part is changed. The variable portion in which the bending position or angle is changed needs a structure for supporting the rear surface of the variable portion in response to the change.

The fixing unit is coupled to the first frame of the display unit and is always positioned at the front side to constitute a part of the front unit. The variable part includes a side part positioned in the side direction of the mobile terminal, and the position of the side part changes according to the position of the second frame. The area of the area located on the front side and the area located on the back side are different from the side part. That is, according to the first state and the second state, a part of the variable part may be a front part, and a part may be a rear part. The variable portion is positioned in the first direction with respect to the fixed

portions

151a and 151b with respect to the mobile terminal, and the end of the variable portion is bent in the rear direction of the mobile terminal and slides on the rear surface of the second frame.

The end of the variable part of the display unit is coupled to a slide frame that guides the slide movement on the rear surface of the second frame, and the slide frame moves on the second frame in the first direction at the same time when the second frame moves in the first direction. As a result, the moving distance of the slide frame moves twice that of the second frame with respect to the first frame. On the other hand, as well shown in FIG. 3 , the first rear portion 1012 of the mobile terminal 100 has an exposed rear portion 1015 exposed to the outside without the display unit 151 being covered even in the first state. may include In the exposed rear part 1015, various buttons, switches, camera 121, physical input unit 120 such as a flash, and a sensor unit 140 such as a proximity sensor 141 or a fingerprint sensor for operation of the mobile terminal 100 ) can be placed. The first rear portion 1012 excluding the exposed rear portion 1015 is covered by the display unit 151 in the first state as shown in FIG. 3(a) and as shown in FIG. 3(b). In the second state, it may be exposed in the rear direction.

In a typical bar-type terminal, the display unit is provided only on the front surface of the terminal. Accordingly, the main camera is disposed on the rear surface of the terminal in order to photograph the object on the other side while looking through the user's display unit 151 . On the other hand, an auxiliary camera is additionally required on the front of the terminal in order to take a picture while looking at the user through the display unit.

However, in the mobile terminal 100 of the present invention, the display unit 151 is located on both the front and rear surfaces thereof. Therefore, when photographing the user himself, the display unit on the same side as the camera 121 , that is, the rear side of the display unit 151 may be used, and when photographing an object opposite to the user, the display on the opposite side to the camera 121 . The front portion of the portion 151 may be used. For this reason, the mobile terminal 100 may use one camera 121 to photograph an object located opposite to the user or photograph the user. The camera may include a plurality of cameras having different angles of view, such as wide-angle, ultra-wide, and telephoto. In addition to the camera, a proximity sensor sound output unit may be located on the exposed rear portion 1015 , and an antenna 116 may be installed. It can be attached using the exposed deco 1015 to protect the camera or sensor of the exposed rear part 1015 and to consider the exterior design aspect. The exposed decor 1015 may have a predetermined pattern or color in consideration of the design aspect without exposing the part corresponding to the camera 121 or the sensor 140 to be transparent, and other parts to not expose the internal parts.

The first side portion 1013 may extend along the edges of the first front portion 1011 and the first rear portion 1012 so as to surround the circumference of the first frame 101 , and may enhance the appearance of the mobile terminal 100 . can be formed However, as mentioned above, since the second frame 102 is accommodated in and movably coupled to the first frame 101 , the relative movement of this second frame 102 with respect to the first frame 101 . A portion of the first frame 101 needs to be opened to allow As well shown in FIG. 2 , as an example, the second frame 102 is movably coupled in the first direction of the first frame 101 , so that the first side portion 1013 has a side surface in the first direction. It is not formed and can open it. Since the first side portion 1013 is exposed to the outside of the mobile terminal 100, an interface unit 160 for connecting a power port or an ear jack or a user input unit 120 such as a volume button may be disposed. When a metal material is included, the first side portion 1013 may serve as an antenna.

The second frame 102 may include a second front portion 1021 disposed in front of the mobile terminal 100 and a second rear portion 1022 disposed in the rear of the mobile terminal 100 . Like the first front portion 1011 and the first rear portion 1012 of the first frame 101 , the second front portion 1021 and the second rear portion 1022 may be formed of a substantially flat plate-shaped member. . In addition, the second frame 102 also accommodates various parts, and should not interfere with the parts accommodated in the first frame 101 during movement. Accordingly, the second front portion 1021 and the second rear portion 1022 may be coupled to each other in a spaced apart state to form a predetermined space, and may have a shape that does not interfere with the components in the first frame 101 . there is.

6 is a side view of the mobile terminal 100 viewed from the third direction, showing a first side portion 1013 of the first frame 101 and a second side portion 1023 of the second frame 102 . The end of the second frame 102 in the first direction is not exposed to the outside because the flexible display unit 151 is located, and the end of the second frame 102 in the second direction should be opened so as not to interfere with the first frame 101 . The second side portion 1023 of the second frame 102 positioned in the third direction (meaning the upper or lower direction in the drawing, or may include both the upper and lower sides) is the second side portion 1023 of the first frame in the first state. It overlaps with the first side 1013 and is not exposed to the outside, but in the second state, since the second frame 102 is drawn out, it may be exposed to the outside.

In addition, the display unit 151 may be bent 180 degrees while being wound in the second frame 102 so as to be disposed on both the front and rear surfaces of the mobile terminal 100 . For such an arrangement of the display 151 , the second frame 102 may include a roller 210 rotatably disposed therein. The roller 210 may be disposed at any position inside the second frame 102 . However, the display 151 must be spread flat on the front and rear surfaces of the mobile terminal 100 in order to provide a user with a good quality screen, and for this deployment, an appropriate tension must be provided to the display 151 . do. To provide adequate tension, a roller 210 may be disposed at the first directional end of the second frame 102 . The roller 210 may extend in the second direction and may be rotatably coupled to the second frame 102 .

The display unit 151 may be wound around the roller 210 while being gently bent with a predetermined curvature. The flexible display unit 151 may include a first surface through which an image is output and exposed to the outside, and an inner surface facing the frame opposite to the first surface. The roller 210 may be installed to freely rotate on the second frame 102 while in contact with the inner surface of the display unit 151 . Accordingly, the roller 210 may actually move the display unit 151 in a lateral direction of the mobile terminal 100 , that is, in a direction perpendicular to the longitudinal direction. As will be described later, when the second frame 102 slides, the display unit 151 moves in different directions (that is, the first direction D1 or In the second direction (D2)), it moves to the front or rear side of the mobile terminal 100 relative to the second frame 102 , and the roller 210 may guide this movement while rotating.

In addition, the roller 210 is disposed adjacent to the end of the second frame 102 in the first direction, and in order to prevent damage to the display unit 151 wound around the roller 210 , the first of the second frame 102 . and a side frame 1024 disposed at the directional end.

The side frame 1024 may extend long in the longitudinal direction (third direction) of the second frame 102 to cover the side portion in the first direction, and accordingly, the roller 210 and the display unit 151 wound thereon. can protect

The location may vary according to the state of the mobile terminal. Since the side part is wound by a roller, the side part may be bent with a predetermined curvature, and the inner surface of the side frame may include a curved surface corresponding to the curvature of the side part.

The side frame 1024 together with the first side portion 1013 of the first frame 101 may substantially form the exterior of the mobile terminal 100 . In addition, in order to minimize interference with components in the first frame 101 during movement, the second frame 102 may omit the side in the second direction.

During the expansion and contraction in the first and second directions D1 and D2, the second frame 102 does not interfere with the first frame 101 so as to prevent the first frame 101, precisely its first front part. 1011 , may overlap the first rear portion 1012 . More specifically, as described above, the display unit 151 may be coupled and supported by the first front portion 1011 of the first frame 101 , and thus the second frame 102 . There is no need to be additionally supported by the second front portion 1021 of Rather, when the second front portion 1021 is interposed between the first front portion 1011 and the display portion 151, the display portion 151 may be moved due to friction with the repeatedly moving second front portion 1021. It may be deformed or damaged. Accordingly, the second front portion 1021 may be disposed below the first front portion 1011 or may be inserted between the first front portions 1011 composed of two sheets. The second rear portion 1022 of the second frame 102 may be disposed in the rear direction of the first rear portion 1012 of the first frame 101 . That is, the front surface of the second rear portion 1022 may face the rear surface of the first rear portion 1012 . In addition, in order to stably support the motion of the second frame 102 , the rear surface of the first rear portion 1012 may contact the front surface of the second rear portion 1022 . By this arrangement, the second rear portion 1022 is exposed to the outside of the first frame, precisely the first rear portion 1012 , and may be coupled to the display unit 151 .

In addition, the second frame 102 can expand and contract the size of the mobile terminal 100 itself, in particular, the front surface of the mobile terminal 100 by expansion and contraction in the first and second directions D1 and D2. In addition, the display unit 151 has to move as much as the expanded or reduced front surface in order to obtain the intended first and second states. However, when fixed to the second frame 102 , the display unit 151 cannot be moved smoothly to fit the front surface of the mobile terminal 100 that is expanded or reduced. For this reason, the display unit 151 may be movably coupled to the second frame 102 .

In more detail, the display unit 151 includes a second region ( 151b), located between the first area 151a and the second area 151b, and wrapped around the roller 210, and moves to the front or the back according to the state change of the mobile terminal 100 It may include three regions 151c. The slide frame 103 may be formed of a plate-shaped member extending long in the longitudinal direction (third direction) of the mobile terminal 100 , and is disposed on the second rear part 1022 in first and second directions (D1, D2). may be movably coupled.

The 1-3

th regions

151a , 151b , and 151c may be connected to each other and form a continuous body of the display unit 151 . In addition, as described above, in order to move the third region 151c to the front or rear of the mobile terminal 100 according to the moving direction of the second frame 102 , the first region 151a is formed by the mobile terminal. It is fixed to the front surface of 100 and the second area 151b may be provided to be movable on the rear surface of the mobile terminal. The configuration of the display unit 151 will be described in more detail below.

The first region 151a may be disposed on the front surface of the mobile terminal 100 , more specifically, on the front surface of the first front part 1011 of the first frame 101 . The first region 151a is fixed to the front of the first frame 101, that is, the first front part 1011, so as not to move even when the second frame 102 is moved, and thus always can be exposed to the front.

The third region 151c is adjacent to the first region 151a in the direction of the second end 151e , and may extend into the second frame 102 to be wound around the roller 210 . The third region 151c may continuously extend from the second frame 102 again and partially cover the second frame 102 , that is, the rear surface of the second rear portion 1022 . On the other hand, the second frame 102, that is, the second rear portion 1022 is adjacent to the first frame 101, that is, the first rear portion 1012 and together form the rear case of the mobile terminal 100, It may be described that the third region 151c is also disposed on the rear surface of the first frame 101 .

The second region 151b is adjacent to the third region 151c, and may be disposed on the rear surface of the mobile terminal 100 , more specifically, on the rear surface of the second rear part 1022 of the second frame 102 . there is. The second region 151b may be coupled to the slide frame 103 without being directly coupled to the second frame 102 .

As a result, the first region 151a is disposed on the front surface of the mobile terminal 100 and is always exposed to the front regardless of the movement of the second frame 102 , and the second region 151b is the mobile terminal 100 . It is disposed on the rear surface of the second frame 102, regardless of the movement can always be exposed to the rear surface. In addition, the third region 151c is disposed between the first and

second regions

151a and 151b, and the front or rear surface of the mobile terminal 100 according to the moving directions D1 and D2 of the second frame 102 . may be selectively placed on the

Due to such a selective arrangement of the third region 151c, as shown in FIG. 4(b) , the first rear portion 1012 of the first frame 101 is disposed in the display unit 151 in the first state. In the second state in which the portion covered by the second and

third regions

151b and 151c and the second rear portion 1022 of the Since the rear part 1022 also moves in the first direction D1 , it may be exposed to the outside of the mobile terminal 100 . In addition, the second front portion 1021 of the second frame 102 is hidden by the first front portion 1011 of the first frame 101 in the first state, but in the second state, the first frame 101 The third area 151c of the display unit 151 that is moved from and is disposed on the front of the mobile terminal 100 may be supported.

The second front portion 1021 is further provided with a separator 1017 located in the rear direction of the second front portion 1021 so as not to affect the internal components when the slide moves to be fastened with the first front portion 1011. can The second front part 1021 may move between the first front part 1011 and the separation plate 1017 according to the sliding movement of the second frame.

However, the third region 151c may be bent by being wound around the roller 210 in the second frame 102 . When switching from the first state to the second state, the third region 151c may extend from the second frame 102 to the front of the mobile terminal 100 while being wound around the roller 210 in either direction. On the other hand, when switching from the second state to the first state, the third region 151c may be contracted from the front side of the mobile terminal 100 to the second frame 102 while being wound around the roller 210 in the opposite direction, and at the same time It is possible to return to the rear surface of the mobile terminal 100 from the second frame 102 .

In a foldable mobile terminal in the form of a book unfolding, only a specific position is repeatedly folded, so that the specific position is easily damaged. On the other hand, the deformable portion of the flexible display unit 151 , that is, the portion wound around the roller 210 may vary according to the first and second states of the mobile terminal 100 , that is, the movement of the second frame 102 . . Accordingly, the mobile terminal 100 of the present invention can significantly reduce deformation and fatigue repeatedly applied to a specific portion of the display unit 151, thereby preventing the display unit 151 from being damaged.

Based on the configuration described above, the overall operation of the mobile terminal 100 will be described as follows. As an example, state change may be performed manually by a user, and the operation of the mobile terminal 100 during such manual state change will be described. However, the operations of the 1-3 th frames 101-103 and the display unit 151 described below are performed when a power source other than the user's power is used, for example, when the driving unit 200 described later is applied. can be performed in the same way.

A rear cover 1025 may be further provided on the rear surface of the second rear portion 1022 so that the rear portion of the display portion located on the rear surface of the mobile terminal 100 is not exposed to the outside. The rear cover 1025 can be used in the first state when a transparent material is used, and when an opaque material is used, the slide frame 103 can be covered so that the moving state is not exposed. That is, the second and third regions of the slide frame 103 and the display unit 151 move in the first and second directions between the spaced space between the second rear part 1022 and the rear cover 1025 . can

7 is a diagram illustrating the driving unit 200 according to an embodiment of the mobile terminal 100, wherein (a) shows a first state and (b) shows a second state. In the mobile terminal 100 of the present invention, the user manually pulls the second frame 102 with respect to the first frame 101 in the first "Num* (D1) or pushes it in the second direction D2. It is possible to change the state of the mobile terminal 100. However, in the manual method, there is a risk of damage when excessive force is applied to the main body of the mobile terminal 100, so that the second frame 102 can be stably moved without distortion. A driving unit 200 using the motor 201 may be further included.

The motor 201 may use a motor 201 that provides rotational force as shown in FIG. 7 , or a linear motor 201 that moves in a straight line. The motor 201 providing the rotational force must have a large diameter in order to provide a large force. As shown in FIG. 7 , two motors 201 may be used to provide a driving force greater than or equal to a predetermined size without increasing the thickness in the limited space of the mobile terminal 100 .

If the moving speed of the second frame 102 is too fast, there is a risk of damage or malfunction, so a planetary gear for reducing the speed of the motor 201 to move at a stable speed may be further included. The planetary gear 202 serves to amplify or attenuate the number of rotations of the motor 201 using a plurality of disk gears having different numbers of teeth. The motor 201 may be fixed to the first frame 101 as shown in (a) of FIG. 7, and as shown in (b) of FIG. Even if the mobile terminal 100 is moved and switched to the second state, the position is fixed.

Since the second frame 102 linearly moves in the first direction or the second direction with respect to the first frame 101, a rack and pinion gear that converts the rotational force of the motor 201 into a linear motion may be used. The pinion gear receiving the rotational force of the motor 201 may be disposed to mesh with the rack gear 205 composed of teeth continuously arranged in the first direction. The pinion gear may be fixed to the first frame 101 together with the motor 201 , and the rack gear 205 may be located in the second frame 102 . Conversely, the rack gear 205 may be disposed on the first frame 101 and the motor 201 and the pinion gear may be disposed on the second frame 102 . Since the motor 201 holds the pinion gear so that the pinion gear does not rotate, the second frame 102 can maintain the first state and the second state, but when a large external force is applied, the pinion gear rotates while the second frame ( 102) may be out of position.

The mobile terminal 100 may further include a stopper (not shown) for fixing the position between the second frame 102 or the rack gear 205 and the first frame 101 so that the mobile terminal 100 is fixed in the first state or the second state. can The stopper is released when a current flows through the motor 201 to allow movement of the second frame 102, and when the motor 201 does not rotate because power is not applied to the motor 201, the second frame ( 102) and the second frame 102 may be fastened to fix the position.

If a pair of driving units 200 are provided symmetrically in the vertical direction (third direction), they can be moved stably, but in order to place batteries, etc. in consideration of the limited mounting space of the mobile terminal 100 As shown in (a) of 7, it should be placed biased to one side. The second frame 102 may further include a linear guide 230 because, depending on the position of the asymmetrical driving unit 200 , the moving speed of the upper end and the lower end is different during the movement of the second frame 102 , which may cause a distorted movement problem. .

The linear guide 230 may be disposed at both ends of the mobile terminal 100 in the third direction, ie, upper and lower, in order to supplement the function of one driving unit 200 biased to one side in the third direction. The linear guide 230 may include a guide rail 231 extending in the first direction and a guide block 232 moving along the guide rail 231 . The guide rail 231 may be disposed on the first frame 101 and the guide block 232 may be disposed on the second frame 102 , and vice versa. In the present embodiment, the guide rails 231 are disposed on the second frame 102 to cover upper and lower sides of the extended portion of the second frame 102 in the second state.

After coupling the guide block 232 to the first frame 101 and coupling the guide rail 231 to the second frame 102 , the guide block 232 and the guide rail 231 may be slide-fastened, but for convenience of fastening. For this, in the state in which the guide block 232 and the guide rail 231 are fastened, the guide block 232 is first fixed to the first frame 101, and then the second frame 102 and the guide rail 231 are coupled. can

In the guide block 232 , a guide groove into which the guide rail 231 is inserted may be formed, and conversely, a rail groove into which a part of the guide block 232 is inserted may be formed in the guide rail 231 . The fastening portion of the guide rail 231 and the guide block 232 may be moved in the first direction or the second direction without being deviated in the thickness direction of the mobile terminal 100 as irregularities are formed. In order to reduce the friction force between the guide block 232 and the guide rail 231, a member with high wear resistance, low frictional resistance, and self-lubrication, such as a bearing or polyoxymethylene (POM), is added inside the guide groove. can do.

8 is a cross-sectional view taken along lines A-A and B-B of FIG. 2 .

As shown in FIG. 2 , when the second frame 102 is converted to the second state while moving in the first direction, the third region 151c located in the rear direction moves in the front direction and the 3 A structure for supporting the rear surface of the region 151c is required. The second front portion 1021 positioned on the front side of the second frame 102 may be positioned on the rear surface of the third region 151c in the second state, but in the first state, the first Since it overlaps with the front part 1011, the first front part 1011 and the second front part 1021 form a step difference. A boundary is generated between the first area 151a and the third area 151c of the flexible display unit 151 due to the step difference between the first front portion 1011 and the second front portion 1021 . The rolling plate 104 may be used as a support structure to fill a space between the second front part 1021 and the third region 151c of the flexible display unit 151 .

The rolling plate 104 may be positioned on the rear surface of the flexible display unit 151 and may have a thickness corresponding to the spaced apart space between the second front unit 1021 and the flexible display unit 151 in the second state. As shown in (a) of FIG. 8 , in the first state, the rolling plate 104 is wound around the roller 210 and is located in the side and rear directions of the mobile terminal 100 , and the second rear of the second frame 102 . The flexible display unit 151 and the rolling plate 104 may be positioned between the unit and the rear cover 1025 that covers the rear surface of the display unit 151 . As shown in (b) of FIG. 8 , when the second state is changed, the rolling plate 104 moves to the front, and the rolling plate 104 may be located in the front portion of the second frame 102 .

Since the third region 151c of the display unit 151 in which the rolling plate 104 is positioned is a portion in which bending deformation occurs when the first state is changed to the second state, the rolling plate 104 also includes the third region 151c. It can be modified corresponding to the modification of . At the same time, the rolling plate 104 must have a predetermined rigidity to maintain a flat state when the flexible display unit 151 is positioned on the front or rear surface. That is, the rolling plate 104 needs a structure that maintains a flat state in the third direction and is bendable in the first direction.

Hereinafter, embodiments related to a control method that can be implemented in the mobile terminal configured as described above will be described with reference to the accompanying drawings. It is apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

9 is a block diagram illustrating a configuration module of a mobile terminal according to an embodiment of the present invention. The block diagram of FIG. 9 is for better explaining the embodiment of the present invention, and the mobile terminal to be described below may be implemented as the mobile terminal shown in FIGS. 1 to 8 .

Referring to FIG. 9 , the mobile terminal 900 according to an embodiment of the present invention may include a body 910 , a display 920 , an input unit 930 , a communication unit 940 , and a control unit 950 .

The body 910 is hardware constituting the mobile terminal 900 and may include a first frame and a second frame.

In one embodiment of the present invention, the second frame may be expandable or retractable from the first frame. Here, the first frame and the second frame may be implemented as the first frame and the second frame described above with reference to FIGS. 1 to 8 . That is, the second frame can be expanded or contracted from the first frame manually or automatically by the above-described structure.

The mobile terminal 900 may further include a driving unit (not shown) for expanding or contracting the second frame. Here, the driving unit may be implemented as the driving unit 200 of FIG. 7 .

The mobile terminal 900 may operate in the extended display mode as the second frame is expanded, and may operate in the reduced display mode as the second frame is contracted. In this case, the extended display mode may correspond to the first state described above with reference to FIGS. 2 and 3 , and the reduced display mode may correspond to the second state.

The display 920 may be coupled to the body 910 so that the display area viewed from the front of the body 910 may be varied as the display 920 is switched between the extended display mode and the reduced display mode. That is, the display 920 may cover the front, side, and rear surfaces of the body 910 . In this case, the display 920 may be implemented as the flexible display unit 151 of FIG. 1 .

In one embodiment of the present invention, as the second frame is expanded, the display portion located on the side of the body 910 may move to the front of the body 910 , and the display portion located on the back of the body 910 may It can move to the front side through the side of the body 910 .

In addition, as the second frame is contracted, the display portion positioned at the front of the body 910 may move to the side of the body 910 or move to the rear through the side of the body 910 . Accordingly, the size of the front display area viewed from the front of the body and the size of the rear display area seen from the rear of the body may be changed.

In an embodiment of the present invention, a state in which the second frame is not expanded, that is, a state in which the mobile terminal 900 is in a reduced display mode may be defined as a default state. Also, a state in which the mobile terminal 900 is in a reduced display mode may be referred to as a first mode, and a state in which the mobile terminal 900 is in an extended display mode may be referred to as a second mode.

The display 920 may display visual information. Here, the visual information may include text, an indicator, an icon, content, an application, an image, and a video. Also, the display 920 may output visual information to the screen based on a control command of the controller 950 .

In particular, the display 920 may divide an area in the extended display mode. In more detail, the display 920 may output different visual information to the divided areas. For example, the display 920 may output a first application to a first area, a second application to a second area, and output a third application to a third area.

Also, the display 920 may output a visual effect. More specifically, the display 920 may not simply output visual information, but may apply an effect to the output visual information. For example, the display 920 may perform black-and-white processing, blur processing, or dimming processing on the output application. Also, the display 920 may output a visual effect to only a partial area.

In particular, as described above with reference to FIG. 1 , the display 920 may be implemented as a touch screen by forming a mutually layered structure or integrally formed with the touch sensor, but the output function and the touch function may be individually controlled. This will be described in detail in the drawings below.

The input unit 930 may receive various inputs of the user for the mobile terminal 900 and transmit the input result so that the control unit 950 may perform an operation corresponding thereto. For example, the input unit 930 may receive an input signal for touching the first area from the user, and transmit the input result to the control unit 950 so that the control unit 950 determines that the first area is selected. .

In an embodiment of the present invention, the input unit 930 may be provided on the display 920 and implemented as a touch screen. In this case, the input unit 930 is provided in the display 920 , but may be controlled separately from an output function of the display 920 . Also, the input unit 930 may be implemented as the input unit 120 of FIG. 1 .

The input unit 930 may sense a touch input from the user. In this case, the input unit 930 may sense a point where a touch input is sensed, a touched area, and a touched pressure together.

The input unit 930 may simply receive an input signal for touching an icon or image from a user, and the input unit 930 may receive a touch drag input signal for touching the icon or image and then dragging it to another location. Also, the input unit 930 may receive a touch drag input signal for dragging after touching the button, and the controller 950 may obtain the drag distance and drag direction of the received touch and drag input signal.

In an embodiment of the present invention, the mobile terminal may receive a signal for executing a payment application through the input unit 930 .

The communication unit 940 may include one or more modules that enable wireless communication between the mobile terminal and another mobile terminal or an external server. In one embodiment of the present invention, the mobile terminal may receive a signal for executing a payment application through the communication unit 940 in addition to the embodiment of receiving the signal through the input unit 930 . For example, the mobile terminal may receive a signal from another terminal requesting payment or an external server through the communication unit 940 . Accordingly, the mobile terminal may execute a payment application. Hereinafter, it will be described in detail.

Also, the communication unit 940 may include a short-range communication module. In particular, in the following embodiments, NFC is used as an example, but it goes without saying that other communication modules may be applied.

In addition, the mobile terminal may further include a Magnetic Stripe Transmission (MST) module. Accordingly, the mobile terminal may generate an MST signal to perform payment through the payment application. Conventionally, a method of performing payment using a physical card including magnetic stripe data has been common, but recently, a method of performing payment through a mobile terminal is also widely used. The MST module may transmit a pulse-modulated magnetic field including magnetic stripe data to a charge terminal (or POS terminal) without swiping the payment card within a predetermined distance. Through this, the user can perform payment by transmitting the MST signal using the mobile terminal after positioning the mobile terminal within a certain distance from the billing terminal without contacting the billing terminal.

The controller 950 may process data, control each unit of the mobile terminal 900 described above, and control data transmission/reception between the units. In the present invention, the controller 950 may be implemented as the controller 180 of FIG. 1 .

Operations performed by the mobile terminal 900 may be controlled by the controller 950 . However, for convenience, in the drawings and the following description, these operations are collectively described as being performed/controlled by the mobile terminal 900 .

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 10 to x. In describing and understanding the embodiments of the present invention below, reference may be made to the contents described above in relation to FIGS. 1 to 9 .

10A and 10B are diagrams for explaining an embodiment of executing a payment application in an extended display mode in a mobile terminal according to an embodiment of the present invention. Figure 10a describes an embodiment of executing the payment application in a state in which the application is being output in the horizontally divided front display area, Figure 10b is the application is running the payment application in the state being output in the vertically divided front display area Examples will be described.

Referring to the first drawing of FIG. 10A , the mobile terminal may output a first application 1010a and a second application 1010b to the front display area 1020 . In this case, the display of the mobile terminal may correspond to the extended display mode. Accordingly, the mobile terminal may horizontally divide the area of the extended display to output the first application 1010a to the upper area and the second application 1010b to the lower area.

In the embodiment of the first drawing of FIG. 10A , since the mobile terminal corresponds to the extended display mode, the front display area 1020 may correspond to the fully expanded state. Accordingly, the rear display area 1030 may correspond to a minimally reduced state.

Hereinafter, the output of the first application 1010a and the second application 1010b will be described based on the embodiment of FIG. 10A , but of course, it may also be applied when the first application 1010a is output in a full screen. .

Referring to the second drawing of FIG. 10A , upon receiving a signal for executing the payment application 1040 , the mobile terminal may output the payment application 1040 to the front display area 1020 .

In more detail, the mobile terminal may receive a signal for selecting the button 1041 as a signal for executing the payment application 1040 . For example, the user may touch the button 1041 output on the edge surface of the front display area 1020 of the mobile terminal.

Also, the mobile terminal may receive a voice signal as a signal for executing the payment application 1040 . For example, the user may say to the mobile terminal “run LG PAY”.

Also, the mobile terminal may receive a request signal for an external POS terminal as a signal for executing the payment application 1040 . For example, when the mobile terminal approaches the POS terminal, the POS terminal may transmit a request signal to the mobile terminal to execute the payment application 1040 .

In addition, in an embodiment of the present invention, when the mobile terminal outputs the payment application 1040 to the front display area 1020 , it may be output based on the location of the fingerprint authentication sensor. More specifically, the payment application 1040 may request fingerprint authentication according to an attribute. In the case of the payment application 1040 that requires fingerprint authentication, the mobile terminal may output the payment application 1040 in consideration of the location of the fingerprint recognition sensor built into the mobile terminal.

Since the mobile terminal can output the payment application 1040 by dividing the display area, the payment application 1040 must be output in consideration of the location of the fingerprint recognition sensor. Accordingly, the user may perform fingerprint recognition through the payment application 1040 output from the expanded display.

Also, when outputting the payment application 1040 in the extended display mode, the mobile terminal may output the first application 1010a and the second application 1010b to the second area 1052 .

More specifically, the mobile terminal may divide and use the extended display in the extended display mode. In this case, when the payment application 1040 is output, the front display area 1020 may be divided and output together with the first application 1010a and the second application 1010b that are being output.

For example, the mobile terminal may output the payment application 1040 to the first area 1051 , and output the first application 1010a and the second application 1010b to the second area 1052 . In this case, the output position of the payment application 1040 may be determined based on the module built into the mobile terminal as described above.

Also, when outputting the payment application 1040 to the first area 1051 , the mobile terminal may output the first application 1010a and the second application 1010b in a manner that covers them. On the other hand, when the mobile terminal outputs the payment application 1040 to the first area 1051 , the mobile terminal may output the first application 1010a and the second application 1010b by reducing the sizes.

Referring to the third drawing of FIG. 10A , when authentication through the payment application 1040 is completed, the mobile terminal may switch the display to the reduced display mode. This is because the display area needs to be reduced when authentication is completed through the payment application 1040 due to the problem of the NFC antenna position. However, when the MST signal can be generated through the payment application 1040 even if the display area is not reduced even after authentication is completed through the payment application 1040 due to the development of technology, the present embodiment may be omitted.

In one embodiment of the present invention, the mobile terminal outputs the payment application 1040 in full screen on the reduced front display area 1020, while displaying the first application 1010a and the second application on the rear display area 1030 ( 1010b) can be output. Accordingly, the user may simultaneously use the payment application 1040 , the first application 1010a , and the second application 1010b .

That is, when authentication is completed through the payment application 1040, the mobile terminal may switch the display to the reduced display mode for payment. Accordingly, the size of the front display area 1020 of the mobile terminal may be reduced to the minimum, and the size of the rear display area 1030 may be enlarged to the maximum.

In addition, when the reduction of the display is completed, the mobile terminal may generate an MST signal to perform payment.

Referring to the fourth drawing of FIG. 10A , when payment is completed through the payment application 1040, the mobile terminal terminates the payment application 1040 and displays the first application 1010a and the second application 1010b on the front display area. (1020) can be output.

Also, as the first application 1010a and the second application 1010b are output to the front display area 1020 , the mobile terminal may turn off the rear display area 1030 . That is, in the reduced display mode, the screen may need to be turned off because the rear display area 1030 is in a state in which it is maximally expanded.

Referring to the fifth drawing of FIG. 10A , in the mobile terminal, before the payment application 1040 is executed, the first application 1010a and the second application 1010b are output from the horizontally divided front display area 1020 , as payment is completed through the payment application 1040, the display is switched to the extended display mode, and the first application 1010a and the second application 1010b are gradually expanded based on the expansion size of the display and can be printed.

More specifically, in the embodiment of FIG. 10 , the mobile terminal displays the first application 1010a and the second application 1010b before the payment application 1040 is executed in the horizontally divided front display area 1020 in the extended display mode. ) can be printed.

Accordingly, when the payment application 1040 is terminated, the mobile terminal needs to output the first application 1010a and the second application 1010b to the expanded display again. In this case, since the mobile terminal corresponds to a state in which the display is switched to the reduced display mode in order to perform payment through the payment application 1040, the display may be expanded. The mobile terminal may expand the sizes of the first application 1010a and the second application 1010b based on the expanded size of the display.

10B may refer to the description of FIG. 10A. That is, in the embodiment of FIG. 10B , a description overlapping with FIG. 10A may be omitted.

More specifically, referring to the first drawing of FIG. 10B , the mobile terminal may output the first application 1010a and the second application 1010b to the front display area 1020 . In this case, the mobile terminal may output the first application 1010a and the second application 1010b to the vertically divided front display area 1020 in the extended display mode. For example, the mobile terminal may output the first application 1010a to the left area and output the second application 1010b to the right area.

Referring to the second drawing of FIG. 10B , upon receiving a signal for executing the payment application 1040 , the mobile terminal may output the payment application 1040 to the front display area 1020 . In particular, when the mobile terminal outputs the payment application 1040 in the extended display mode, the front display area 1020 is vertically divided into the first area 1051 and the second area 1502 as shown in FIG. 10A or as shown in FIG. 10B . Can be split horizontally.

For example, the mobile terminal may output the first application 1010a and the second application 1010b to the first area 1051 , and may output the payment application 1040 to the second area 1052 . . In this case, the output positions of the first application 1010a, the second application 1010b, and the payment application 1040 may be changed. Also, the mobile terminal may output the payment application 1040 to cover the first application 1010a and the second application 1010b.

Referring to the third drawing of FIG. 10B , when authentication through the payment application 1040 is completed, the mobile terminal may switch the display to the reduced display mode. Here, authentication may refer to authentication as to whether there is an authority to perform payment through the payment application 1040 before performing payment. For example, it may include a method of authenticating a user having the authority to use the payment application 1040 through methods such as logging in through an ID and password, logging in through a public certificate, or fingerprint recognition, face recognition, and the like.

At this time, the mobile terminal may output the payment application 1040 in full screen on the reduced front display area 1020 , and output the first application 1010a and the second application 1010b to the rear display area 1030 . there is. In addition, in the embodiment of FIG. 10A, the first application 1010a and the second application 1010b are horizontally divided and output to the rear display area 1030, and in the embodiment of FIG. 10B, the first application 1010a and the second application 1010b are vertically divided and output Although the embodiment has been described, it is not limited thereto.

Referring to the fourth drawing of FIG. 10B , when payment is completed through the payment application 1040 , the mobile terminal terminates the payment application 1040 and displays the first application 1010a and the second application 1010b on the front display area 1020 ) can be printed. In this case, the mobile terminal may turn off the rear display area 1030 .

Referring to the fifth drawing of FIG. 10B , the mobile terminal displays the first application 1010a and the second application 1010b before the payment application 1040 is output from the vertically divided front display area 1020, As payment is completed through the payment application 1040, the display may be switched to the extended display mode.

Thereafter, the mobile terminal may output the first application 1010a and the second application 1010b to the vertically divided front display area 1020 . In particular, the mobile terminal may output the first application 1010a and the second application 1010b to extend from the vertical dividing line 1060 .

More specifically, the mobile terminal may output the first application 1010a and the second application 1010b while expanding the display in the reduced display mode. At this time, since the first application 1010a and the second application 1010b are output from the vertically divided front display area 1020, the mobile terminal is divided into the first application 1010a and the second application 1010b. It can be output as if it extends from the vertical dividing line 1060 which is the center.

11A and 11B are diagrams for explaining an embodiment of executing a payment application in a reduced display mode in a mobile terminal according to an embodiment of the present invention. Hereinafter, descriptions overlapping those of FIGS. 10A and 10B will be omitted.

Referring to the first drawing of FIG. 11A , the mobile terminal may output a first application 1110a and a second application 1110b to the front display area 1120 . In this case, the display of the mobile terminal may correspond to the reduced display mode. That is, unlike FIG. 10A , the mobile terminal may horizontally divide the area of the reduced display to output the first application 1110a to the upper area and the second application 1110b to the lower area.

In addition, since the display of the mobile terminal corresponds to the reduced display mode, the front display area 1120 may correspond to a minimally reduced state, and the rear display area 1130 may correspond to a maximum expanded state. However, in the first drawing of FIG. 11A , the rear display area 1130 may correspond to an off state.

Referring to the second drawing of FIG. 11A , in response to receiving a signal for executing the payment application 1140 , the mobile terminal may output the payment application 1140 on the front display area 1120 .

In one embodiment of the present invention, as the mobile terminal outputs the payment application 1140 to the front display area 1120, at least one of the first application 1110a and the second application 1110b is displayed on the rear display area 1130. can be printed on For example, the mobile terminal may independently output an application having a higher priority among the first application 1110A to the second application 1110b on the rear display area 1130 .

Also, the mobile terminal may output the output in the portrait mode or the landscape mode to the rear display area 1130 based on at least one attribute of the output first application 1110a and the second application 1110b.

In addition, since the mobile terminal is already in the reduced display mode when the payment application 1140 is executed, it is possible to perform authentication and payment without reducing the display.

Referring to the third drawing of FIG. 11A , when payment is completed through the payment application 1140 , the mobile terminal terminates the payment application 1140 and displays the first application 1110a and the second application 1110b on the front display area 1120 . ) and turn off the rear display area 1130 .

Since the embodiment of Figure 11a describes an embodiment in which the payment application 1140 is executed and terminated in the reduced display mode, the first application 1110a and the second application (1110a) and the second application ( 1110b) may be originally output to the front display area 1120 .

11B illustrates an embodiment in which the payment application 1140 is executed in the rear display area 1130 .

Referring to the first drawing of FIG. 11B , the mobile terminal may output the first application 1110a and the second application 1110b to the front display area 1120 in the reduced display mode.

At this time, since the display of the mobile terminal corresponds to the reduced display mode, the front display area 1120 may correspond to a minimized state, and the rear display area 1130 may correspond to a maximum expanded state.

Referring to the second drawing of FIG. 11B , in response to receiving a signal for executing the payment application 1140 , the mobile terminal may output the payment application 1140 to the rear display area 1130 . That is, in the embodiment of FIG. 11A , it has been described that the payment application 1140 is output on the front display area 1120 in consideration of the location of the NFC antenna, but the location of the NFC antenna and the fingerprint recognition sensor are located on the rear display area 1130 . It may be available even in a state in which the payment application 1140 is output. In this case, the mobile terminal may output the payment application 1140 to the rear display area 1130 . Accordingly, the user may use the payment application 1140 through the rear display area 1130 while using the first application 1110a and the second application 1110b in the front display area 1120 .

Accordingly, the mobile terminal may perform authentication and payment through the payment application 1140 output on the rear display area 1130 .

Referring to the third drawing of FIG. 11B , when payment is completed through the payment application 1140 , the mobile terminal terminates the payment application 1140 and displays the first application 1110a and the second application 1110b on the front display area 1120 . ) and turn off the rear display area 1130 .

Referring to the first drawing of FIG. 12A , the mobile terminal may output a first application 1210a and a second application 1210b in the reduced display mode. In this case, since the mobile terminal corresponds to the reduced display mode, the front display area 1220 may correspond to a minimum reduced state and the rear display area 1230 may correspond to a maximum expanded state. In this case, the rear display area 1230 of the mobile terminal may correspond to an off state.

When the mobile terminal detects a signal that the mobile terminal is turned over through a gyro sensor or the like, the mobile terminal may output a lock screen on the rear display area 1230 . More specifically, referring to the second drawing of FIG. 12A , the mobile terminal may output a lock screen to the rear display area 1230 .

Here, the lock screen 1270 may correspond to a screen including only a clock widget before the mobile terminal completes user authentication as a home screen or a screen in a standby state before outputting an application. Also, the mobile terminal may output the home screen or other application only when user authentication is completed through the lock screen 1270 .

In other words, since users have a need to use essential widgets such as a clock while keeping the display area in an off state, the mobile terminal does not use the display, but uses an always on display (AOD) screen. can be printed out. In this case, the AOD screen may include a lock screen 1270 or a clock widget.

In particular, since the mobile terminal of the present invention can use the front display area 1220 and the rear display area 1230 at the same time, the first application 1210a and the second application 1210b in use in the front display area 1220 , and an AOD screen may be output in the rear display area 1230 .

Also, the mobile terminal may receive a knock on signal from the user to output a home screen or other application after the lock screen 1270 . For example, the user may input a preset signal to the lock screen 1270 . Accordingly, the mobile terminal may switch the rear display area 1230 on which the lock screen 1270 is output to an on state.

Unlike FIG. 12A, FIG. 12B describes an embodiment in which flip mode is turned on through setting of a mobile terminal. Here, the flip mode corresponds to a mode in which the rear display area 1230 is automatically switched to the display-on state when the mobile terminal detects a flipping operation through a gyro sensor or the like. That is, unlike the embodiment of FIG. 12A , when the flip mode is turned on, the mobile terminal may immediately switch the display to the on state without outputting the lock screen on the rear display area 1230 .

Referring to the first drawing of FIG. 12B , the mobile terminal may output a first application 1210a and a second application 1210b to the front display area 1220 in the reduced display mode.

Referring to the second drawing of FIG. 12B , when detecting a flip operation, the mobile terminal switches the rear display area 1230 to an on state and outputs a message confirming whether an application is output to the rear display area 1230 . can do. For example, the mobile terminal may output the phrase "If you want to use the rear display area, touch the screen" on the rear display area 1230 . This is to prevent a case in which the mobile terminal erroneously detects a flipping motion when the user is lying and holding the mobile terminal.

Referring to the third drawing of FIG. 12B , the mobile terminal may output a first application 1210a to the rear display area 1230 in response to a signal 1280 for selecting a message output to the rear display area 1230 . . In this case, the first application 1210a may correspond to the last focused application. For example, when the mobile terminal detects a flip operation after the user touches the first application 1210a through the front display area 1220, the first application 1210a may correspond to the last focused application. there is.

13A shows the front display area 1320 and the rear display area 1330 is kept off, and in FIG. 13B shows the front display area 1330 is used and the front display area 1320 is used. ) describes an embodiment of keeping the off state.

More specifically, referring to the left drawing of FIG. 13A , the mobile terminal may output a message confirming whether to use the front display area 1330 before switching the front display area 1330 to the on state. can

Referring to the right drawing of FIG. 13A , the mobile terminal outputs an application to the front display area 1320 and the rear display when detecting the first signal 1381 touching the front display area 1320 . The region 1330 may be switched to an off state.

On the other hand, referring to the left drawing of FIG. 13B , the mobile terminal may output a message confirming whether to use the rear display area 1330 before switching the rear display area 1330 to the on state.

Referring to the right diagram of FIG. 13B , when the mobile terminal detects the second signal 1382 touching the rear display area 1330 , it outputs an application to the rear display area 1330 , and the front display The region 1320 may be switched to an off state.

Referring to the left drawing of FIG. 14 , the mobile terminal may detect a signal 1483 for simultaneously selecting the front display area 1420 and the rear display area 1430 . For example, the user may simultaneously touch the front display area 1420 and the rear display area 1430 .

Referring to the right diagram of FIG. 14 , the mobile terminal may generate a haptic feedback according to detecting a signal 1483 . Thereafter, the mobile terminal may output an application to the front display area 1420 and the rear display area 1430 , respectively.

15A to 15E are diagrams for explaining an embodiment of switching from an extended display mode to a reduced display mode in a mobile terminal according to an embodiment of the present invention. In this case, FIGS. 15A to 15E describe an embodiment in which a mobile terminal is used in a portrait mode. In addition, in the embodiment of FIGS. 15A to 15E , the driver is located at the right edge of the mobile terminal and the front display area 1520 disappears to the right to become the rear display area 1530. However, the driver is located at the other edge The same can be applied even when located.

15A illustrates an embodiment in which a mobile terminal is switched from an extended display mode to a reduced display mode while turning over in a horizontal direction (or horizontal direction).

Referring to FIG. 15A , the mobile terminal may output a first application 1510a , a second application 1510b , and a third application 1510c to the front display area 1520 in the extended display mode. In this case, the mobile terminal may output three applications by dividing the screen on the extended display.

The mobile terminal may detect a movement of turning the mobile terminal from left to right or from right to left. Accordingly, the mobile terminal may switch the display from the extended display mode to the reduced display mode.

In an embodiment of the present invention, upon detecting the flipping motion, the mobile terminal may reduce the front display area 1520 and expand the rear display area 1530 while switching the display to the reduced display mode.

In this case, the mobile terminal may maintain the rear display area 1530 in an off state until the conversion to the reduced display mode is completed. Accordingly, the mobile terminal is not burdened with what to output on the rear display area 1530 in the process of switching to the reduced display mode.

When the conversion to the reduced display mode is completed, the mobile terminal may output the application output from the front display area 1520 to the rear display area 1530 .

In this case, the mobile terminal may determine the application output from the rear display area 1530 based on the direction of the flipping operation. For example, when the mobile terminal is turned over to the right, the mobile terminal displays the second application 1510b and the third application 1510c located in the right area of the front display area 1520 on the rear display area 1530. can be printed out.

15B illustrates another embodiment of switching from an extended display mode to a reduced display mode while flipping the mobile terminal in a horizontal direction.

Referring to FIG. 15B , the mobile terminal may output a first application 1510a , a second application 1510b , and a third application 1510c to the front display area 1520 in the extended display mode.

In this case, unlike the embodiment of FIG. 15A , the mobile terminal may output the second application 1510b and the third application 1510c to the rear display area 1530 as the rear display area 1530 is expanded.

The mobile terminal may output the second application 1510b and the third application 1510c based on the size to which the rear display area 1530 is expanded.

When the conversion to the reduced display mode is completed, the mobile terminal may output the application output from the front display area 1520 to the rear display area 1530 . For example, the mobile terminal may output the second application 1510b and the third application 1510c that have been output to the right area of the front display area 1520 to the rear display area 1530 .

15C illustrates another embodiment of switching from an extended display mode to a reduced display mode while flipping the mobile terminal in a horizontal direction.

Referring to FIG. 15C , the mobile terminal may output a first application 1510a, a second application 1510b, and a third application 1510c to the front display area 1520 in the extended display mode. However, unlike FIGS. 15A and 15B , FIG. 15C describes an embodiment in which the first application 1510a is located in the right area, and the second application 1510b and the third application 1510c are located in the left area.

Upon detecting the flipping motion, the mobile terminal may reduce the front display area 1520 and expand the rear display area 1530 while switching the display from the extended display mode to the reduced display mode.

In this case, it may be set that the first application 1510a is output to the front display area 1520 , and the second application 1510b and the third application 1510c are output to the rear display area 1530 . This may be determined by the properties of the application or the settings of the mobile terminal.

However, when the driving unit is located in the right area, when the second application 1510b and the third application 1510c to be output to the rear display area 1530 are output to the left area of the front display area 1520, movement A problem occurs in that the terminal cannot naturally output the second application 1510b and the third application 1510c to the rear display area 1530 .

To prevent this, when an application to be output on the rear display area 1530 is output in a direction opposite to the direction of the reduced display area, the mobile terminal reduces the application to be placed on the rear display area 1530 through software. It can be arranged in the direction of the display area.

More specifically, before being reduced, the mobile terminal may output the first application 1510a to the right area and output the second application 1510b and the third application 1510c to the left area.

As the mobile terminal receives the signal for switching to the reduced display mode, it outputs the first application 1510a to the left area in software (that is, not output on the actual display), and the second application 1510b and the third The application 1510c may be placed in the right area. Thereafter, as the mobile terminal is switched to the reduced display mode, the second application 1510b and the third application 1510c may be naturally output to the rear display area 1530 .

Of course, this embodiment can be applied even when the driving unit is located on the left side.

15D illustrates another embodiment of switching from the extended display mode to the reduced display mode while flipping the mobile terminal in the horizontal direction.

Referring to the first drawing of FIG. 15D , the mobile terminal may output a first application 1510a, a second application 1510b, and a third application 1510c to the front display area 1520 in the extended display mode. An embodiment in which the first application 1510a is located in the right area and the second application 1510b and the third application 1510c are located in the left area will be described similarly to FIG. 15C . Also, in the embodiment of FIG. 15D , it is assumed that the first application 1510a corresponds to a focused application.

In an embodiment of the present invention, the mobile terminal may receive a signal for switching from the extended display mode to the reduced display mode. The signal for switching to the reduced display mode may include various signals such as a signal for selecting a button for switching to the reduced display mode, a voice signal, and the like.

Referring to the second drawing of FIG. 15D , in the process of switching the display to the reduced display mode, the mobile terminal has an effect as if the application output to the front display area 1520 disappears based on the boundary line 1540 of the front display area 1520 can be printed out. Here, the boundary line 1540 is a virtual line located at the boundary where the boundary line 1540 is not actually output, but the first application 1510a, the second application 1510b, and the third application 1510c are outputted. can respond to

More specifically, since the first application 1510a is a focused application, the mobile terminal outputs the first application 1510a to the front display area 1520 as it is switched to the reduced display mode, and the rear display area 1530 ) to output the second application 1510b and the third application 1510c.

To this end, as the front display area 1520 is reduced, the mobile terminal outputs partial areas of the second application 1510b and the third application 1510c that are being output to the front display area 1520 on the front display area 1520 . Instead, it should be output to the rear display area 1530 .

In this case, the mobile terminal may output the second application 1510b and the third application 1510c as disappearing based on the boundary line 1540 .

In particular, in the process of switching to the reduced display mode, the mobile terminal may ignore touch recognition in the area where the second application 1510b and the third application 1510c are output. That is, in order to prevent a user's malfunction, the mobile terminal may deactivate reception of user inputs of applications other than the focused application during the conversion of the reduced display mode.

Referring to the third drawing of FIG. 15D , partial areas of the second application 1510b and the third application 1510c that have disappeared from the second drawing of FIG. 15D may be output on the rear display area 1530 .

15E illustrates another embodiment of switching from the extended display mode to the reduced display mode while turning the mobile terminal in a horizontal direction.

Referring to the first drawing of FIG. 15E , the mobile terminal may output a first application 1510a , a second application 1510b , and a third application 1510c to the front display area 1520 in the extended display mode. In this case, the first application 1510a may be output to the left area, and the second application 1510b and the third application 1510c may be output to the right area.

In an embodiment of the present invention, the mobile terminal may receive a signal for switching from the extended display mode to the reduced display mode.

Referring to the second drawing of FIG. 15E , the mobile terminal receives a signal 1550 for selecting the second application 1510b or the third application 1510c of the front display area 1520 in the process of switching the display to the reduced display mode. can receive

When the mobile terminal receives a signal for switching to the reduced display mode, it is common for the second application 1510b and the third application 1510c to move to the rear display area 1530 because the driving unit is located in the right area. However, when receiving the signal 1550 for selecting the second application 1510b or the third application 1510c, the mobile terminal sets the selected second application 1510b or the third application 1510c as the focused application. can

Accordingly, referring to the third drawing of FIG. 15E , the mobile terminal reduces the size of the first application 1510a and moves it to the rear display area 1530, and displays the second application 1510b and the third application 1510c. The size can be expanded to fit the aspect ratio. At this time, similar to the above-described embodiment, the mobile terminal may deactivate reception of the user input in the area where the first application 1510a is output.

Referring to the fourth drawing of FIG. 15E , the mobile terminal may output a part of the first application 1510a that has disappeared from the front display area 1520 on the rear display area 1530 .

Accordingly, the mobile terminal may set the application output to the area moving from the front display area 1520 to the rear display area 1530 as the focused application and maintain the output in the front display area 1520 .

16A to 16D are diagrams for explaining an embodiment of switching between an extended display mode and a reduced display mode in a mobile terminal according to an embodiment of the present invention. At this time, FIGS. 16A to 16D describe an embodiment in which the mobile terminal is used in the landscape mode. Accordingly, the driving unit may be shown as being located at the lower edge of the mobile terminal.

If the mobile terminal is turned over in the vertical direction (or in the vertical direction) while using the landscape mode, there is no problem in that the application is turned over and output. On the other hand, when switching from the extended display mode to the reduced display mode while flipping the mobile terminal in the horizontal direction (or horizontal direction) while using the mobile terminal in the landscape mode, a problem occurs in that the application is turned over and output. Fig. 16A explains this problem.

More specifically, referring to the first drawing of FIG. 16A , the mobile terminal may output a first application 1610a , a second application 1610b , and a third application 1610c to the front display area 1620 . In this case, the first application 1610a, the second application 1610b, and the third application 1610c may be output in the landscape mode.

Referring to the second diagram of FIG. 16A , the mobile terminal may detect an operation of turning the mobile terminal over in the horizontal direction. For example, the mobile terminal may detect a movement of turning the mobile terminal from left to right. Accordingly, the mobile terminal may switch the display from the extended display mode to the reduced display mode.

In this case, when the mobile terminal does not perform any operation, the third application 1610c may be output to the left area of the rear display area 1630 and the second application 1610b may be output to the right area.

That is, referring to the third drawing of FIG. 16A , the mobile terminal may output the second application 1610b and the third application 1610c to the rear display area 1630 in an inverted state.

In order to prevent this, the following examples will be described.

16B illustrates an embodiment of switching from the extended display mode to the reduced display mode while using the mobile terminal in the landscape mode.

Referring to the first drawing of FIG. 16B , the mobile terminal may output a first application 1610a , a second application 1610b , and a third application 1610c to the front display area 1620 . In this case, the first application 1610a, the second application 1610b, and the third application 1610c may be output in the landscape mode.

Referring to the second drawing of FIG. 16B , when the mobile terminal receives a signal for switching to the reduced display mode, the application to be placed on the rear display area 1630 may be vertically inverted by software.

In more detail, the mobile terminal may vertically invert the second application 1610b and the third application 1610c disposed on the front display area 1620 on software according to detecting the flipping operation. Also, the mobile terminal may turn off the front display area 1620 upon detecting the flipping operation.

Accordingly, the mobile terminal may output the second application 1610b and the third application 1610c in the normal direction on the rear display area 1630 .

Referring to the third drawing of FIG. 16B , when the conversion to the reduced display mode is completed, the mobile terminal outputs the second application 1610b to the left area of the rear display area 1630 and the third application 1610c to the right area ) can be printed.

16C illustrates an embodiment of switching from the extended display mode to the reduced display mode while using the mobile terminal in the landscape mode.

In this case, an embodiment in which the first application 1610a is located in the upper area, the second application 1610b is located in the lower left area, and the third application 1610c is located in the lower right area will be described. In an embodiment of the present invention, the mobile terminal may receive a signal for switching from the extended display mode to the reduced display mode.

Referring to the second drawing of FIG. 16C , in the process of converting the display to the reduced display mode, the mobile terminal has an effect as if the application output to the front display area 1620 disappears based on the boundary line 1640 of the front display area 1620 can be printed out.

In this case, when the first application 1610a is the focused application, the mobile terminal may output the second application 1610b and the third application 1610c as if they gradually disappear in the direction of the boundary line 1640 .

Accordingly, referring to the third drawing of FIG. 16C , the mobile terminal may output partial areas of the second application 1610b and the third application 1610c that disappear to the boundary line 1640 on the rear display area 1630 .

16D illustrates an embodiment of switching from the reduced display mode to the extended display mode while using the mobile terminal in the landscape mode.

Referring to (a) of FIG. 16D , the mobile terminal outputs a first application 1610a to the front display area 1620 , and a second application 1610b and a third application 1610c to the rear display area 1630 . can be printed out.

In this case, since the mobile terminal uses the display in the reduced display mode, the front display area 1620 may correspond to a minimum reduced state, and the rear display area 1630 may correspond to a maximum expanded state.

In an embodiment of the present invention, the mobile terminal may receive a signal for switching to the extended display mode.

Referring to (b) of FIG. 16D , when the mobile terminal receives a signal for switching to the extended display mode, the second application 1610b and the third application 1610 being output on the rear display area 1630 are vertically inverted. can do it

Thereafter, the mobile terminal may output the first application 1610a, the second application 1610b, and the third application 1610c to the expanded front display area 1620 . That is, the mobile terminal may output the first application 1610a at the top, and output the vertically inverted second application 1610b and the third application 1610c to the first application 1610a in the lower area.

17A illustrates an embodiment in which a camera application is selectively used in a front display area and a rear display area. In the embodiment of Fig. 17A, it is assumed that the mobile terminal is in a reduced display mode. That is, the front display area 1720 may correspond to a minimized state, and the rear display area 1730 may correspond to a maximum expanded state.

Referring to the left drawing of FIG. 17A , the mobile terminal may output a camera application 1710 to the front display area 1720 and maintain the rear display area 1730 in an off state.

In this case, the mobile terminal may output the first icon 1711 indicating the front camera and the front display area on the first image preview output to the camera application 1710 . Here, the first image preview is an image preview captured through the front camera.

In an embodiment of the present invention, the mobile terminal may receive a signal for selecting the first image preview. For example, the mobile terminal may receive a touch input signal to swipe up and down after touching the first image preview.

Accordingly, referring to the right drawing of FIG. 17A , the mobile terminal may change the front display area 1720 to an off state and output the camera application 1710 to the rear display area 1730 . In this case, the mobile terminal may output the second image preview through the camera application 1710 .

In this case, the mobile terminal may output the second icon 1712 indicating the rear camera and the rear display area on the second image preview output to the camera application 1710 . Here, the second image preview is an image preview captured through the rear camera.

That is, in general, in the case of a mobile terminal, the sensor of the rear camera has a higher image quality than the sensor of the front camera. Accordingly, since the mobile terminal according to an embodiment of the present invention can selectively use the front display area 1720 and the rear display area 1730 , a high-quality selfie camera can be used through the rear display area 1730 .

17B illustrates an embodiment in which the camera application is used simultaneously in the front display area and the rear display area. In the embodiment of Fig. 17B, it is assumed that the mobile terminal is in a reduced display mode. That is, the front display area 1720 may correspond to a minimized state, and the rear display area 1730 may correspond to a maximum expanded state.

Referring to the left drawing of FIG. 17B , the mobile terminal may output a camera application to the front display area 1720 and maintain the rear display area 1730 in an off state. In this case, the mobile terminal may output the first icon 1711 indicating the front camera and the front display area on the first image preview 1741 output to the camera application. Here, the first image preview 1741 is characterized in that it is an image preview captured through the front camera.

In an embodiment of the present invention, the mobile terminal may receive a signal for selecting the first image preview 1741 . For example, the mobile terminal may receive a long touch input signal for touching the first image preview 1741 for a preset period of time or longer.

Referring to the diagram on the right of FIG. 17B , as the mobile terminal receives a signal, it outputs a first image preview 1741 captured through the front camera on the front display area 1720, and a second image captured through the rear camera. An image preview 1742 may be output. In this case, the mobile terminal may output the first icon 1711 indicating the front camera and the front display area on the first image preview 1741 .

Also, the mobile terminal may output the second image preview 1741 captured through the rear camera and the first image preview 1741 captured through the front camera to the rear display area 1730 . In this case, the mobile terminal may output a second icon 1712 indicating the rear camera and the rear display area on the second image preview 1741 .

That is, when the mobile terminal receives a preset signal while the application is being output in only one display area, the mobile terminal may output the application in the other display area as well. On the other hand, although not shown in the drawings, when the mobile terminal receives a preset signal while the application is being output on both display areas, the display of the area where the signal is received may be switched off.

Also, the mobile terminal may output the first image preview 1741 captured through the front camera to the front display area 1720 larger than the second image preview 1742 captured through the rear camera.

Similarly, the mobile terminal may output the second image preview 1742 captured through the rear camera to the rear display area 1730 larger than the first image preview 1741 captured through the front camera.

That is, the mobile terminal may largely output an image preview captured through the front camera in the front display area 1720 , and may largely output an image preview captured by the rear camera in the rear display area 1730 .

17C illustrates another embodiment of using the camera application in the front display area and the rear display area at the same time. In the embodiment of Fig. 17C, it is assumed that the mobile terminal is in a reduced display mode. That is, the front display area 1720 may correspond to a minimized state, and the rear display area 1730 may correspond to a maximum expanded state.

Referring to the left drawing of FIG. 17C , the mobile terminal may output a first image preview 1741 captured through the front camera and a second image preview 1742 captured through the rear camera in the front display area 1720 . there is. In this case, the mobile terminal may output the first icon 1711 indicating the front camera and the front display area on the first image preview 1741 .

Also, the mobile terminal may output a second image preview 1742 captured through the rear camera and a first image preview 1741 captured through the front camera in the rear display area 1730 . In this case, the mobile terminal may output the first icon 1712 indicating the rear camera and the rear display area on the second image preview 1742 .

In an embodiment of the present invention, the mobile terminal may receive a signal for selecting the front display area 1720 or the rear display area 1730 . For example, the mobile terminal may receive a touch signal for swiping down after touching a specific area of the rear display area 1730 .

In this case, the mobile terminal may output the second image preview 1742 captured through the rear camera to be larger than the first image preview 1741 captured through the front camera. In this case, the mobile terminal may output a third icon 1713 indicating the rear camera and the front display area on the second image preview 1742 .

Also, the mobile terminal may output the first preview image 1741 captured through the front camera and the second image preview 1742 captured through the rear camera to the rear display area 1730 according to the signal. Similarly, the mobile terminal may output the first image preview 1741 captured through the front camera to be larger than the second image preview 1742 captured through the rear camera. In this case, the mobile terminal may output a fourth icon 1714 indicating the front camera and the rear display area on the first image preview 1741 .

17D shows an embodiment of switching from the extended display mode to the reduced display mode while the camera application is output.

Referring to the left drawing of FIG. 17D , the mobile terminal may output an image preview on the front display area 1720 through a camera application. In this case, the mobile terminal may output the first icon 1711 indicating the front camera and the front display area on the image preview. In this case, the image preview is an image preview captured through the front camera.

When the mobile terminal detects a signal for flipping the mobile terminal, the image preview may be vertically inverted and output on the rear display area 1730 .

More specifically, the mobile terminal may detect an operation of turning the mobile terminal upside down in the extended display mode. In an embodiment of the present invention, the mobile terminal may recognize the vertical flip operation as a signal for switching from the extended display mode to the reduced display mode.

Accordingly, the mobile terminal may switch the display to the reduced display mode and output an image preview on the rear display area 1730 . In this case, the image preview is an image preview captured through the rear camera. However, the mobile terminal may output an image preview by vertically inverting the raw image of the rear camera sensor.

That is, when the user who used the front display area 1720 turns the mobile terminal upside down, the mobile terminal may output an image preview captured through the rear camera on the rear display area 1730 . At this time, since the direction of the rear camera is located downward, the mobile terminal inverts the raw image of the rear camera sensor up and down so that the user can see a normal image preview.

In particular, the mobile terminal performing the control method of FIG. 18 is characterized in that it includes a display coupled to the body so that the display area visible from the front of the body can be changed as the display mode is switched between the extended display mode and the reduced display mode.

In step S1810, the mobile terminal may output the first application to the front display area. That is, the mobile terminal may output at least one of the first application, the second application, and the third application to the horizontally or vertically divided front display area.

In step S1820, the mobile terminal may output the payment application to the front display area in response to receiving a signal for executing the payment application. Also, the mobile terminal may divide the front display area to output the payment application to the first area and output the first application to the second area. In this case, the first area may be determined based on the location of the fingerprint authentication sensor. Also, in another embodiment, as the payment application is output on the front display area, the mobile terminal may output the first application on the rear display area visible from the back of the body. In this case, the mobile terminal may output in the portrait mode or the landscape mode based on the attribute of the first application output to the rear display area.

In step S1830, when authentication is completed through the payment application, the mobile terminal may switch the display to the reduced display mode.

In an embodiment of the present invention, as payment is completed through the payment application, the mobile terminal may output the first application to the front display area and switch the rear display area to an off state.

In addition, when the first application and the second application are output from the horizontally divided front display area, the mobile terminal switches the display to the extended display mode as payment is completed through the payment application and displays the first application and the second application It can be output while gradually expanding based on the expansion size of the display.

In addition, when the first application and the second application are output from the vertically divided front display area, the mobile terminal outputs the payment application to cover the first application and the second application as it receives a signal to execute the payment application. can

In addition, when the first application and the second application are output from the vertically divided front display area, the mobile terminal switches the display to the extended display mode as payment is completed through the payment application, and the first application and the second application can be output to extend from the vertical dividing line.
