Meanwhile, the sensing unit 1400 senses at least one of information in the mobile terminal, surrounding environment information surrounding the mobile terminal, and user information, and generates a corresponding sensing signal. The control unit 1800 may control the driving or operation of the mobile terminal 1000 or may perform data processing, function or operation related to the application program installed in the mobile terminal 1000 based on the sensing signal. Representative sensors among various sensors that may be included in the sensing unit 1400 will be described in more detail.

First, the proximity sensor 1410 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity thereof, without mechanical contact using an electromagnetic force or infrared rays. The proximity sensor 1410 may be disposed in the inner area of the mobile terminal or the proximity sensor 1410 near the touch screen.

Examples of the proximity sensor 1410 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 1410 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 1410 can sense a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch location, have. Meanwhile, the controller 1800 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 1410 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Further, the control unit 1800 can control the mobile terminal 1000 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a contact touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 1510) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

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

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits corresponding data to controller 1800. Thus, the control unit 1800 can know which area of the display unit 1510 is touched or the like. Here, the touch controller may be a separate component from the control unit 1800, and may be the control unit 1800 itself.

On the other hand, the control unit 1800 can perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 1000 or an application program being executed.

Meanwhile, the touch sensor may be configured to detect the touch input using different methods in the activated and deactivated states of the display unit 1510. [ At this time, the different method may be related to the activation period of the touch sensor. More specifically, the touch sensor may be activated at different periods depending on whether the display unit 1510 is activated or not. That is, the touch sensor can sense the touch input applied to the touch sensor with different activation periods according to whether the display unit 1510 is activated or not.

For example, in a state in which the display unit 1510 is inactivated, the touch sensor may be activated at a predetermined period. In this case, the specific period may be a period corresponding to a time greater than zero. In a state in which the display unit 1510 is activated, the touch sensor can be always operated in the activated state. That is, in this case, the activation period of the touch sensor may be 0 or a period having a time very close to 0.

The activation of the touch sensor can be distinguished by using the power consumption of the touch sensor. For example, if the power consumption of the touch sensor is less than a predetermined reference value based on 0, the touch sensor is in a deactivated state, and if the power consumption of the touch sensor is greater than the predetermined reference value , It can be said that it is activated.

 When the display unit 1510 is in an active mode (hereinafter referred to as an 'active mode'), the touch sensor continues to be activated and can wait for the touch input to the display unit 1510 have. Alternatively, when the display unit 1510 is in a deactivated state (referred to as a 'doze mode' hereinafter), the touch sensor may be activated every predetermined period.

On the other hand, the shorter the specific period in which the touch sensor is activated, the faster the touch input sensing the touch of the display unit 1510 is, but the power consumed by the touch sensor can be increased accordingly. In contrast, the longer the period in which the touch sensor is activated, the smaller the power consumed by the touch sensor, but the speed at which the touch input to tap the display unit 1510 may be slowed down.

Accordingly, the specific period may be set so as to increase the efficiency of power consumption while sensing the touch input that hits the display unit 1510, such that the sensing speed is not recognized by the user. For example, a specific period may be set such that the touch sensor is inactivated and activated about 20 times per second (1 Hz).

During the activated state of the display unit 1510, the touch sensor may also be activated. In the activated state, the activation period T of the touch sensor may be zero or very close to zero. Alternatively, in a state in which the touch sensor is activated, the period of the touch sensor may be several times shorter than the specific period in which the touch sensor is activated in a state in which the display unit 1510 is inactivated. That is, the touch sensors can be activated at different periods depending on whether the display unit 1510 is activated or not.

On the other hand, in the doze mode in which the display unit 1510 is inactivated and the touch sensor is periodically activated, a predetermined touch input by the touch sensor (for example, The controller 1800 can switch the doze mode to the active mode in which the display unit 1510 and the touch sensor are activated.

In addition, the touch sensors can be driven at different periods based on the state of the display unit 1510. [ For example, when the display unit 1510 is in the closed state, the doze mode is executed, and when the display unit 1510 is switched from the closed state to the open state, the active mode can be executed.

On the other hand, the touch sensors and the proximity sensors as described above can be used independently or in combination with each other for a short (or touch) touch, a long touch, a multi touch, a drag various methods such as touch, flick touch, pinch-in touch, pinch-out touch, swype touch, hovering touch, It is possible to sense the touch of the user.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. On the other hand, the control unit 1800 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor.

In the following, various embodiments may be embodied in a recording medium readable by a computer or similar device using, for example, software, hardware, or a combination thereof.

2A and 2B are conceptual diagrams showing an example of a portable electronic device related to the present invention in different directions. Referring to FIGS. 2A and 2C, the disclosed mobile terminal 1000 includes a body of a bar-shaped mobile terminal. However, the present invention is not limited thereto and can be applied to various structures such as a folder type, a flip type, a slide type, a swing type, and a swivel type in which a watch type, a clip type, a glass type or two or more bodies are relatively movably coupled . A description of a particular type of mobile terminal, although relevant to a particular type of mobile terminal, is generally applicable to other types of mobile terminals.

Here, the body of the mobile terminal can be understood as a concept of referring to the mobile terminal 1000 as at least one aggregate. Alternatively, the body of the mobile terminal may be referred to as the body.

The mobile terminal 1000 includes a case (e.g., a frame, a housing, a cover, and the like) that forms an appearance. As shown, the mobile terminal 1000 may include a case 101, which may include a front case and a rear case. Various electronic components are disposed in the inner space formed by the combination of the front case and the rear case. At least one middle case may be additionally disposed between the front case and the rear case.

The case may be configured to be deformable together with the display unit 1510 which is flexible by an external force in consideration of the characteristics of the flexible display unit 1510. [ That is, the flexible display portion 1510 is formed to be bent or folded together with the case 101.

For example, the case may be formed of plastic, thin glass, fiber components, a thin metal (e.g. aluminum), a fabric, a deformable material such as silicone, or a combination of these materials.

On the other hand, the portion of the case may be formed of a dielectric material or a low conductive material, and at least a part of the structure constituting the case or case may be formed of a metal element.

A display unit 1510 is disposed on a front surface of the body of the mobile terminal to output information. As shown in the figure, the display unit 1510 may be mounted on the case to form a front surface of the mobile terminal body.

In some cases, the electronic component can be mounted on the rear case. Electronic parts that can be mounted on the rear case include a detachable battery, an identification module, and a memory card. In this case, a rear cover for covering the mounted electronic component can be detachably coupled to the rear case. Therefore, when the rear cover is detached from the rear case, the electronic parts mounted on the rear case are exposed to the outside. Meanwhile, the rear cover may be provided with an opening for exposing the camera 1210 or the sound output unit 1520 to the outside.

The mobile terminal 1000 may be configured such that one case provides the internal space, unlike the above example where a plurality of cases provide an internal space for accommodating various electronic components. In this case, a universal mobile terminal 1000 in which synthetic resin or metal is connected from the side to the rear side can be realized.

Meanwhile, the mobile terminal 1000 may include a waterproof unit (not shown) for preventing water from penetrating into the body of the mobile terminal. For example, the waterproof portion may include a waterproof member that is provided between the display portion 1510 and the front case, between the front case and the rear case, or between the rear case and the back cover, and seals the inner space at the time of engagement.

The mobile terminal 1000 may include a display unit 1510, an audio output unit 1520, a light output unit 1540, a second camera 1210, and a microphone 1220.

2A and 2B, a display unit 1510 is disposed on a front surface of a body of the mobile terminal, and a camera 1210, an audio output unit 1520, (1220), and a rear input unit (1230a, 1230b). The mobile terminal 1000 in which the optical output unit 1540 is disposed will be described as an example. However, these configurations are not limited to this arrangement. These configurations may be excluded or replaced as needed, or placed on different planes.

As shown in FIG. 2A, a display unit 1510 may be disposed on a front surface of the mobile terminal 1000. The display unit 1510 displays (outputs) the information processed by the mobile terminal 1000. For example, the display unit 1510 may display execution screen information of an application program driven by the mobile terminal 1000, or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

The display unit 1510 may include a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED) 3D display), and an electronic ink display (e-ink display).

Meanwhile, the display unit 1510 may be configured to be deformable by an external force. The deformation may be at least one of warping, bending, folding, twisting, and curling of the display portion 1510. The deformable display portion 1510 may be referred to as a 'flexible display portion 1510' or a 'ben double display portion 1510'. Here, the flexible display unit 1510 may include both a general flexible display and electronic paper (e-paper) and combinations thereof. That is, the flexible display unit 1510 means a display unit 1510 that is formed to be flexible so that at least a part thereof can be folded.

A typical flexible display is a sturdy display that is lightweight and does not break easily, such as paper, which is fabricated on a thin, flexible substrate that can flex, bend, fold, twist or curl like a conventional flat panel display.

In addition, the electronic paper is a display technology to which general ink characteristics are applied, and the point that the reflected light is used is different from the conventional flat panel display. The electronic paper can be changed by using a twist ball or electrophoresis (electrophoresis) using a capsule.

In a state in which the flexible display portion 1510 is not deformed (e.g., a state having an infinite radius of curvature), the display area of the flexible display portion 1510 becomes flat. In the non-deformed state, the display region may be curved in a state deformed by an external force (for example, a state having a finite radius of curvature). As shown in the figure, the information displayed in the deformed state may be time information output on the curved surface. Such visual information is realized by independently controlling the emission of a sub-pixel arranged in a matrix form. The unit pixel means a minimum unit for implementing one color.

The flexible display portion 1510 may be placed in a bent state (e.g., a state in which the flexible display portion 1510 is bent up and down or left and right) rather than a flat state in the non-deformed state. In this case, when an external force is applied to the flexible display portion 1510, the flexible display portion 1510 may be deformed into a flat state (or a less bent state) or a more bent state.

The flexible display portion 1510 may be formed of a plurality of layers of materials. For example, the flexible display unit 1510 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made to the flexible touch screen, the control unit 1800 (180, see FIG. 1) can perform control corresponding to the touch input. The flexible touch screen may be configured to sense the touch input not only in the non-deformed state but also in the deformed state. The touch sensor may be disposed on a substrate of the display, or may be provided inside the display.

As such, the flexible display portion 1510 may form a flexible touch screen with the touch sensor, in which case the touch screen may function as a user input 1230 (see FIG. 1A).

On the other hand, the state change of the flexible display unit 1510 is not limited to the external force. For example, when the flexible display unit 1510 is in an unmodified state, it may be transformed into a deformed state by a command of a user or an application. More specifically, the mobile terminal 1000 includes a driving unit (not shown). When the predetermined condition is satisfied, the mobile terminal 1000 can be transformed into a deformed state without being deformed by driving the driving unit, not by an external force.

The mobile terminal 1000 according to an embodiment of the present invention may be provided with a deformation sensing unit that can sense a deformation of the flexible display unit 1510. [ Such deformation sensing means may be included in the sensing unit 1400 (see FIG. 1).

The deformation detecting unit may be provided in the flexible display unit 1510 or the case 101 to sense information related to the deformation of the flexible display unit 1510. Here, the information related to the deformation may be the direction in which the flexible display portion 1510 is deformed, the degree of deformation, the deformed position, the deformation time, and the acceleration at which the deformable flexible display portion 1510 is restored, In addition, it may be various information that can be detected due to warping of the flexible display unit 1510.

The control unit 1800 may change the information displayed on the flexible display unit 1510 or change the information displayed on the flexible display unit 1510 based on the information related to the deformation of the flexible display unit 1510, It is possible to generate a control signal for controlling the function of the controller.

For example, when the flexible display unit 1510 is bent in response to an external physical force, the controller 1800 controls the flexible display unit 1510 in accordance with the bent direction of the flexible display unit 1510, the bent angle, The screen image previously displayed on the display unit 1510 can be rearranged, separated, synthesized, or changed. More specifically, when the flexible display unit 1510 is bent inward by the external force, the control unit 1800 can display the screen images displayed on the flexible display unit 1510 to be close to each other. On the contrary, when the flexible display unit 1510 is bent outward by the external physical force, the screen images displayed on the flexible display unit 1510 can be displayed to be spaced apart from each other.

Meanwhile, the mobile terminal 1000 according to the present modification may include a case for accommodating the flexible display unit 1510. [ The case 101 may be configured to be deformable together with the flexible display unit 1510 by an external force in consideration of the characteristics of the flexible display unit 1510. [ That is, the flexible display unit 1510 is formed to be bent with the case.

For example, the case may be formed of plastic, thin glass, fiber components, a thin metal (e.g. aluminum), a fabric, a deformable material such as silicone, or a combination of these materials.

On the other hand, the portion of the case may be formed of a dielectric material or a low conductive material, and at least a part of the structure constituting the case or case may be formed of a metal element.

Meanwhile, as shown in FIG. 2B, one or a plurality of rear input units 1230a and 1230b may be provided on the rear surface of the mobile terminal case as another example of the user input unit 1230. FIG. The rear input units 1230a and 1230b are operated to receive commands for controlling the operation of the mobile terminal 1000, and input contents may be variously set. For example, commands such as power on / off, start, end, scrolling, and the like, adjustment of the size of sound outputted from the sound output unit 1520, switching to the touch recognition mode of the display unit 1510, Can receive. The rear input unit may be implemented as a touch input, a push input, or a combination thereof.

The rear input units 1230a and 1230b may be disposed to overlap with the front display unit 1510 in the thickness direction of the mobile terminal body. The rear input units 1230a and 1230b may be disposed at positions adjacent to both ends of the left and right sides of the case. The rear input units 1230a and 1230b are positioned on the rear surface of the mobile terminal 1000 in a flat state where the case is not bent and when the left and right ends of the case 101 are bent so as to face each other, It can be located on the front. However, the present invention is not limited thereto, and the position and the number of the rear input unit can be changed.

Meanwhile, the mobile terminal 1000 may include a fingerprint recognition sensor for recognizing the fingerprint of the user, and the controller 1800 may use the fingerprint information sensed through the fingerprint recognition sensor as authentication means. The fingerprint recognition sensor may be embedded in the flexible display unit 1510 or the user input units 1230a and 1230b.

The microphone 1220 is configured to receive the user's voice, other sounds, and the like. The microphone 1220 may be provided at a plurality of locations to receive stereo sound.

A rear camera 1210b may be disposed on a rear surface of the portable device body. Although not shown in the drawing, when the front camera 1210a is disposed on the front surface of the body of the mobile terminal, the rear camera 1210b has a photographing direction substantially opposite to the front camera 1210a.

The front camera 1210a may be disposed in an opening formed in a part of the flexible display unit 1510. [ Alternatively, the front camera 1210a may be disposed in an opening formed in a part of the case disposed on the front side.

The rear camera 1210b processes an image frame of a still image or moving image obtained by the image sensor in the photographing mode or the video communication mode. The processed image frame may be displayed on the flexible display unit 1510 and stored in the memory 1700. [

The rear camera 1210b may comprise a plurality of lenses arranged along at least one line. The plurality of lenses may be arranged in a matrix form. Such a camera can be named an 'array camera'. When the camera 1210 is an array camera, images can be taken in various ways using a plurality of lenses, and a better quality image can be obtained.

The flash 124 may be disposed adjacent to the rear camera 1210b. The flash 124 illuminates the subject toward the subject when the subject is photographed by the rear camera 1210b.

Further, the electromagnetic wave generator 1300 may be disposed adjacent to the rear camera 1210b. The electromagnetic wave generator 1300 emits the generated electromagnetic wave when the rear camera 1210b is activated.

The body of the mobile terminal may be provided with at least one antenna for wireless communication. The antenna may be embedded in the body of the mobile terminal or formed in the case. For example, an antenna constituting a part of the broadcast receiving module 1110 (see FIG. 1A) may be configured to be fetchable from the body of the mobile terminal. Alternatively, the antenna may be formed in a film type and attached to the inner surface of the rear cover, or a case including a conductive material may be configured to function as an antenna.

The light output unit 1540 is configured to output light for notifying the occurrence of an event. Examples of the event include a message reception, a call signal reception, a missed call, an alarm, a schedule notification, an email reception, and reception of information through an application. The control unit 1800 may control the light output unit 1540 to terminate the light output when the event confirmation of the user is detected.

In addition, the battery (not shown) included in the mobile terminal 1000 may be configured to be deformable together with the flexible display unit 1510 by an external force in consideration of the characteristics of the flexible display unit 1510. In order to implement the battery, a stack and folding method in which battery cells are stacked on top of one another may be applied.

Although not shown in the drawings, the interface unit 1600 (see FIG. 1) may be disposed on a side surface of the body of the mobile terminal. The interface unit 1600 is a path through which the mobile terminal 1000 can be connected to an external device. For example, the interface unit 1600 may include a connection terminal for connection with another device (e.g., earphone, external speaker), a port for short-range communication (e.g., an infrared port (IrDA Port), a Bluetooth port A wireless LAN port, or the like), or a power supply terminal for supplying power to the mobile terminal 1000. The interface unit 1600 may be implemented in the form of a socket for receiving an external card such as a SIM (Subscriber Identification Module) or a UIM (User Identity Module) or a memory card for storing information.

The battery (not shown) may be configured to receive power through a power cable connected to the interface unit 1600. In addition, the battery may be configured to be wirelessly chargeable through a wireless charger. The wireless charging may be implemented by a magnetic induction method or a resonance method (magnetic resonance method).

The mobile terminal 1000 according to an exemplary embodiment of the present invention, which can include at least one of the above-described components, can be configured as a new form factor that can be expanded and used like a book. More specifically, the mobile terminal can be a flexible electronic device in which the main body of the electronic device is folded and unfolded in spite of a change in length occurring in layers in the thickness direction at the time of folding.

Hereinafter, the structure of the flexible display unit 1510 and the structure of the flexible electronic device related to the change of the shape of the flexible display unit 1510 will be described in detail with reference to the accompanying drawings.

First, the external features of the mobile terminal according to an embodiment of the present invention will be described.

FIG. 3A is a conceptual diagram illustrating an example in which a display unit 1510 forms a single plane in a mobile terminal according to the present invention. FIG. Is a conceptual diagram showing the folded state.

Referring to these drawings, the mobile terminal includes a case having an appearance, a display unit 1510 disposed on the front surface, and a sensing unit (see FIG. 1, 1400, or deformation sensing unit) for sensing deformation of the display unit 1510 .

The display unit 1510 is formed to be capable of bending or folding. Here, the folding refers to a state in which a radius of curvature of a part of the body of the mobile terminal is kept smaller than a reference value, and in other words, it corresponds to a folded state. In the case of folding, the screens of the display portion 1510 are brought into contact with or close to each other.

In contrast, bending refers to a state in which a radius of curvature of a part of the body of the mobile terminal is maintained to be greater than the reference value, that is, a bent state.

Folding and bending may also be distinguished by the degree of bending. For example, it is defined as folding if it is bent more than a predetermined angle, and can be defined as bending if it is bent equal to or less than the predetermined angle. Further, even when the radius of curvature is greater than a predetermined angle, bending can be defined when the radius of curvature is larger than the reference value.

Referring to these figures, in a state where the display unit 1510 forms a single plane, at least a part of the display unit 1510 can be changed to a state where the shape is changed. For example, the display unit 1510 may be folded and folded. That is, the display unit 1510 may be configured to have a first state (see FIG. 3A) in which a specific region is plane, and a second state in which the specific region is folded into a curved surface.

In this case, the connection portion 1030 may be folded along the curved trajectory. The curved trajectory may be a part of the circumference of the circle or a part of the circumference of the ellipse.

In addition, the display unit 1510 may include a plurality of folding regions. In this case, the left and right ends of the body of the mobile terminal may each be folded to provide a dual foldable display.

4A and 4B are conceptual diagrams illustrating a light-transmitting region and an opaque region of the mobile terminal of the present invention. 4C is a cross-sectional view of the folded state of the mobile terminal of the present invention.

4A and 4B, the body part of the present invention includes a first body part 1010 and a second body part 1020, and a connection part 1030 for connecting the first and second body parts 1010 and 1020 at a predetermined angle ). The display unit 1510 is disposed on one side of the body. The display unit 1510 is configured to be transparent so that the user can view the outside through the display unit 1510. For example, the display unit 1510 may be a transparent LCD (Liqid Crystal Display).

Although not specifically shown in the drawing, a window may be formed on the display unit 1510. For example, the window is made of a light-transmitting and flexible material, a polyethylene terephthalate (PET) film, or a thin glass. However, a window may contain a portion that can not transmit light. The portion through which the light of the window is transmitted may have an area corresponding to the display element. Accordingly, the user can recognize the time information output from the display units 1510 and 251 from the outside.

 A touch sensor (not shown) may be disposed between the window and the display unit 1510 to sense a touch input to the window. The touch sensor may be mounted on the rear surface of the window or may be formed integrally with the display unit 1510. The touch sensor is made of light transmissive and converts a change in voltage, capacitance, and the like into an electrical input signal so as to detect a touch input.

One part of the body part of the mobile terminal according to the present invention is formed as a transparent area. The body portion can be formed of plastic, thin glass, fiber components, thin metal (e.g. aluminum), fabric, deformable material such as silicone or rubber, or a combination of these materials. In addition, the light transmitting region may be formed of a light transmitting material such as a polyethylene terephthalate (PET) film or a thin glass. However, the present invention is not limited thereto, and the body may further include an additional case or a cover.

For example, the body part may include a front case that forms at least a part of the front surface of the main body, and a rear case that forms at least a part of the rear surface. The rear case may be a space in which the electronic parts are mounted, The rear cover may be detachably coupled. In this case, the rear cover may be provided with an opening for exposing the camera 1210 and the sound output unit 1540 to the outside. Also, at least one rear input unit 1230a, 1230b (see FIG. 2a) may be provided on the rear surface of the mobile terminal 1000. FIG.

The frame supporting the display part 1510 and constituting the body part may be made of a light transmitting material. For example, at least one area of the first body part 1010 is made of a light-transmitting material, and the area where the transparent display part 1510 is disposed may be formed to be transparent. In addition, an image output by the transparent display unit 1510 can be viewed through both sides of the first body part 1010. The connection portion 1030 may also be made of a light-transmitting material. Although the bezel portion supporting the edge of the display portion 1510 of the first body portion 1010 is shown as opaque in the drawing, the present invention is not limited thereto. The second body part 1020 is made of an opaque material.

The display unit 1510 is implemented as a flexible display capable of bending or folding and the first and second body portions 1010 and 1020 are bent at an angle by the connection unit 1030, It can be folded or folded. Referring to FIG. 4B, the first and second body portions 1010 and 1020 may be folded to face each other due to deformation of the connection portion 1030. The mobile terminal 1000 according to the present embodiment includes first and second body portions 1010 and 1020 having substantially the same size.

Referring to FIGS. 4B and 4C, the first and second body portions 1010 and 1020 define a flat state as a first state, and the first and second body portions 1010 and 1020 are folded State is defined as the second state. In the second state, the display portion 1510 is folded in a state of being disposed between the first and second body portions 1010 and 1020. That is, in the mobile terminal 1000, the angle of the first and second body parts 1010 and 1020 is set such that one side of the body part in which the display part 1510 is disposed is disposed inward by the connection part 1030 Can be adjusted. When the first and second body parts 1010 and 1020 are folded, the other surface of the body part forms an outer appearance of the mobile terminal.

The internal space of the second body part 1020 is electrically connected to various electronic parts electrically connected to the circuit board 1810 (see FIG. 1) and the circuit board 1810 (see FIG. 1) 1) may be disposed on the second body part 1020. [

Accordingly, since the electronic parts and the like are not disposed in the first body part 1010 formed as the light-transmitting area, the user can receive the image emitted by the transparent display part 1510 more clearly.

The mobile terminal according to the present invention further includes a touch sensing unit 1011 formed on the other surface of the first body 1010. The touch sensing unit 1011 is arranged to face one area of the display unit 1510. [ The touch sensing unit 1011 senses a touch input of a user on the other side of the first body unit 1010.

In addition, the mobile terminal 1000 includes a coating layer 1012 formed on one surface of the first body portion 1010 corresponding to the light-transmitting region. The coating layer 1012 may be formed between the display portions 1510, but is not limited thereto.

The image output from the display unit 1510 can be recognized by the user through the light emitting region of the first body unit 1010. In this case, the amount of light reflected from the outside by the coating layer 1012 decreases, and the amount of light emitted from the transparent display unit 1510 becomes greater than the amount of reflected light. As a result, the image formed by the light emitted from the display unit 1510 can be recognized more clearly, and the visibility of the transparent display is formed.

Other mobile terminals 1000 in FIG. 7A include a muscle strength sensor 1420 and a Hall sensor 1430. The muscle strength sensor 1420 is disposed on the second body part 1020 and is formed in an area adjacent to the connection part 1030. A change in the distance between the first and second body portions 1010 and 1020 and a change in the amount of the incoming light are detected.

Although not shown in the figure, the mobile terminal 1000 can detect light by forming a transparent window formed to cover the muscle tone sensor 1420. When the angle between the first and second body portions 1010 and 1020 is less than about 90 degrees, the degree of change in the angle between the first and second body portions 1010 and 1020 Can be detected. For example, when the angle between the first and second body portions 1010 and 1020 is reduced by the coordinate sensor 1420, the control unit 1800 controls the display unit 1510 corresponding to the light- The display unit 1510 may control the display unit 1510 to increase the transparency of one area of the display unit 1510. [

Meanwhile, the Hall sensor 1430 detects the first and second states. The Hall sensor 1430 is disposed in the second body part 1020. For example, the hall sensor 1430 may be formed on the bezel portion that supports the display portion 1510 and forms the second body portion 1020. The first body part 1010 includes a magnet part 1431 corresponding to the hall sensor 1430. It is preferable that the magnet portion 1431 is arranged to face each other in a second state in which the first and second body portions 1010 and 1020 are overlapped. That is, the magnet portion 1431 may be formed on the bezel portion supporting the display portion 1510 of the first body portion 1010.

The controller 1800 determines the first state or the second state when a change in magnetism of the magnet unit 1431 is detected by the Hall sensor 1430.

However, the sensing unit is not limited to the myoelectricity sensor and the hall sensor. For example, the sensing unit may include a sensor module that senses a degree of deformation of the connection unit 1030 and senses an angle change of the first and second body units 1010 and 1020. The mobile terminal 1000 according to the present invention can control the display unit 1510 and the touch sensing unit 1011 by sensing an angle change of the first and second body units 1010 and 1020. Hereinafter, a method of controlling the mobile terminal 1000 based on the angle change will be described in detail.

5A is a flowchart illustrating a method of controlling a mobile terminal according to an exemplary embodiment of the present invention. 5B to 5E are conceptual diagrams for explaining a control method of a mobile terminal according to various embodiments of the present invention.

5A and 5B, screen information is output to a transparent display unit 1510 disposed on one side of the first and second body units 1010 and 1020 (S301). The display unit 1510 may be divided into the first and second display regions 1510a and 1510b by the first and second body portions 1010 and 1020. [ The first and second display areas 1510a and 1510b may be divided based on the connection part 1030. [

For example, in the display unit 1510, the first display area 1510a outputs first screen information 310, and the second display area 1510b outputs second screen information 320 . The first and second screen information 310 and 320 may correspond to execution screens of different applications, or may correspond to a home screen page or a predetermined image.

The control unit 1800 senses an angle change between the first and second body units 1010 and 1020 by the sensing unit 1400 in step S302 and controls the first body 1010 and the second body 1010 based on the changed angle. (Step S303). In step S303, the transparency of the area of the first screen information 310 overlapped with the first screen information 310 is changed.

Referring to FIG. 5B, when the angle between the first and second body portions 1010 and 1020 is reduced based on the external force in the first state, the transparency of the first screen information 310 increases. Accordingly, a finger is displayed through the first screen information 310 corresponding to the light-transmitting region. Thin solid lines, and thick solid lines in accordance with the degrees of the fingers being projected through the light-transmitting region on the drawing.

The mobile terminal 1000 may include a Polymer Dispersed Liquid Crystal (PDLC) layer that overlaps and changes in transparency according to an electrical signal. In this case, the controller 1800 adjusts the transparency of the polymer dispersed liquid crystal (PDLC) layer so that the image output from the display unit 1510 can not be recognized on the other side of the body unit can do. The polymer dispersed liquid crystal (PDLC) layer may be an independent structure disposed on the first body part 1010 so as to be overlapped with the display part 1510, . ≪ / RTI >

When the angle between the first and second body portions 1010 and 1020 is changed based on the deformation of the connection portion 1030, that is, when the angle between the first and second body portions 1010 and 1020 is changed, 1020 are folded at predetermined angles, the transparency of the first screen information 310 is increased.

More specifically, when a voltage is applied to the polymer dispersed liquid crystal, the directions of the liquid crystal molecules are uniformly arranged, so that the refractive indices of the liquid crystal molecules become equal to each other and become transparent. That is, when the first and second body portions 1010 and 1020 are bent to have a specific angle, the display portion 1510 applies a specific voltage to the polymer dispersed liquid crystal layer constituting the display portion 1510, The transparency of the display unit 1510 can be controlled.

The control unit 1800 activates the touch sensing unit 1011 formed on the other side of the first body 1010 based on the transparency (S304). For example, when the transparency of the first screen information 310 is about 20% or more, the controller 1800 may activate the touch-touch sensing unit 1011 to receive the touch input of the user. That is, the control unit 1800 activates the touch sensing unit 1011 when the first and second body units 1010 and 1020, which are set to have predetermined transparency values, form a reference angle.

The controller 1800 maintains the touch sensing unit 1011 in an inactive state when the first and second body units 1010 and 1020 form an angle larger than the predetermined angle. Accordingly, in the first state, reception of the touch input of the user is interrupted.

Accordingly, an object (for example, a user's finger) passes through the first screen information 310 superimposed on the light-transmitting area, and the user is placed on the rear surface of the body part and the first screen information 310 The touch input can be applied to one area of the touch sensing unit 1011 which is overlapped.

According to the present invention, when the transparency of the screen information displayed on the light-transmitting region is adjusted by the angle between the first and second body portions, Lt; / RTI > Accordingly, the user can control the mobile terminal while supporting the bent state of the first and second body parts with the fingers and receiving the screen information.

Referring to FIG. 5C, a control method for controlling the first screen information based on the touch input sensed by the touch sensing unit 1011 will be described. In the first state, the first display area 1510a of the display unit 1510 outputs third screen information 330, and the second display area 1510b outputs the third screen information 330 And outputs a related image 331 related thereto. The related image 331 may correspond to a part of the content included in the third screen information 330 or an execution screen of an application related to the content. For example, if the third screen information 330 is an execution screen of a gallery application, the related image 331 may correspond to any one of a plurality of images included in the execution screen.

When the first and second body parts 1010 and 1020 form a certain reference angle, the controller 1800 controls transparency of the third screen information 330 and activates the touch sensing part 1011 .

The control unit 1800 overlaps the selected image 332 selected from the plurality of images on the third screen information 330 based on the touch input sensed by the touch sensing unit 1011 And controls the display unit 1510 to output the output. The selection image 332 may be displayed in an area corresponding to the coordinates of the touch input applied to the touch sensing unit 1011. [ The transparency of the selected image 332 may be different from the transparency of the third screen information 330. For example, the third screen information 330 may have a specific transparency, and the selected image 332 may be opaque.

The control unit 1800 can perform a specific function using the selected image 332 based on the touch input sensed by the touch sensing unit 1011. [ For example, the display unit 1510 may be configured to apply a continuous touch input to the selected image 332 to share the selected image 332, to change the storage space, or to output the selected image 332 to the second display area 1510b Can be controlled.

Referring to FIG. 5D, a control method for executing a preset function based on the touch input sensed by the touch sensing unit 1011 will be described. The first display area 1510 a outputs the first screen information 310 and the second display area 1510 b outputs the third screen information 330. The display unit 1510 outputs the first screen information 310 having a specific transparency based on the first and second body units 1010 and 1020 bent to have the reference angle.

The controller 1800 selects a first image 310a included in the first screen information 310 based on the touch input sensed by the touch sensing unit 1011. [ The control unit 1800 is applied on the display unit 1510 and executes a predetermined function using the first image 310a based on the front touch superimposed on the touch input.

For example, the first image 310a may be included in the home screen page and correspond to an icon corresponding to the application. In this case, the control unit 1800 may control the display unit 1510 to delete the icon on the first screen information 310 based on the touch input and the front touch.

Although not shown in the drawings, the predetermined functions are not limited thereto. For example, the control unit 1800 may execute an application corresponding to the first image 310a, temporarily hide the first image 310a, or temporarily hide the first image 310a, The display unit 1510 can be controlled so as to be output to the area 1510b.

Referring to FIG. 5E, a method of controlling the touch input sensed by the touch sensing unit 1011 and the touch by the front touch will be described. When the first and second body portions 1010 and 1020 have a reference angle, the display unit 1510 outputs the first screen information 310 having a specific transparency, and the touch sensing unit 1011 Activated.

The controller 1800 selects a second image 310b included in the first screen information 310 based on the touch input sensed by the touch sensing unit 1011. [ The control unit 1800 controls the display unit 1510 to output the pop-up image 311b related to the second image 310b to the first display area 1510a.

For example, when the second image 310b corresponds to a folder image including a plurality of information (icons), the pop-up image 311b corresponds to screen information including the plurality of information (icons) . The control unit 1800 may control the display unit 1510 such that the pop-up image 311b disappears when the touch input is canceled.

Meanwhile, the controller 1800 can select any one of the plurality of pieces of information by the front touch while the pop-up image 311b is output. Also, the controller 1800 may control the selected information based on the front touch. For example, the display unit 1510 may delete the third image 311c selected based on the front touch.

According to the present exemplary embodiments, even when the first and second body portions 1010 and 1020 form the reference angle and the touch sensing unit 1011 receives the touch input, the display unit 1510 also performs a front touch And can select an image to be displayed. In addition, when the touch input and the front touch are detected together, the specific function is immediately executed, so that the user can perform a desired function more quickly.

The controller 1800 controls the display unit 1510 to output the first event information 510 on the first screen information 310 based on the received event.

The control unit 1800 may output the first event information 510 to have the specific transparency and reduce the transparency of the first screen information 310. [ For example, the control unit 1800 may control the display unit 1510 to output the first screen information 310 in an opaque state.

That is, an object (user's finger) existing on the other side of the body part can be recognized through one area of the display unit 1510 from which the first event information 510 is output.

Although not shown in the drawing, the controller 1800 may delete the first event information 510 and control the first screen information 310 to have the specific transparency again after a predetermined time passes have.

According to this embodiment, if an event is received, the event can be easily checked on the basis of the touch input on the other side of the body part.

Referring to FIG. 6B, the display unit 1510 outputs second event information 520 related to the received event to the status bar at the upper end of the first display area 1510a. The second event information 520 is output to the status bar to have the specific transparency. In this case, the controller 1800 controls the display unit 1510 to reduce the transparency of the first screen information 310. For example, the first screen information 310 may be opaque.

The controller 1800 controls the display unit 1510 to output the status screen information 521 including the second event information 520 based on the continuous touch input applied to the second event information 520. [ . The status screen information 521 may be output to have the specific transparency. However, the transparency of the status screen information 521 is not limited to the specific transparency.

According to the present exemplary embodiment, when a specific event is received, the transparency of the screen information that has been output previously becomes opaque and the transparency of the event information is increased and output, so that the user can more easily confirm the received event.

And a list screen 340b associated with the list screen 340b. The list screen 340b includes a plurality of contents arranged and includes additional contents to be output based on a touch input applied along one direction. For example, the controller 1800 controls the display unit 1510 to output the additional content based on a dragging-type touch input applied upward in the list screen 340b in the first state, Can be controlled.

The controller 1800 controls the display unit 1510 to change one area of the list screen 340b to a transparent area 341b when the first and second body parts 1010 and 1020 form a reference angle. . That is, the transparent area 341b may be formed to have the specific transparency, and the remaining area of the list screen 340b may be opaque.

Also, the controller 1800 activates at least one area of the touch sensing unit 1011. For example, a part of the touch sensing unit 1011 corresponding to the transparent area 341b may be activated.

Accordingly, the user applies the touch input to the touch sensing unit 1011 corresponding to the transparent area 341b while viewing the list screen 340b as a whole to display the list screen 340b and the fourth screen information 340a Can be controlled.

Referring to FIG. 6D, a control method of controlling transparency based on a touch input applied to the touch sensing unit 1011 will be described. The first display area 1510a outputs the first screen information 310 and the second display area 1510b outputs the third screen information 330. [ However, the present invention is not limited to this, and the display unit 1510 can output a single piece of continuous screen information.

The control unit 1800 activates the touch sensing unit 1011 when the first and second body units 1010 and 1020 form a reference angle. The control unit 1800 may change the transparency of the first screen information 310. [ The controller 1800 may control the display unit to adjust the transparency of one area of the first screen information 310 corresponding to the coordinates of the touch input when the touch input unit senses a touch input by the touch sensing unit 1011. [ 1510).

For example, the transparency of a portion 310c of the first screen information 310 expanded by a specific range based on a point where the touch input is applied can be increased or decreased. In addition, when the point where the touch input is applied is changed, a part 310c of the first screen information 310 in which the transparency is changed may be changed.

Accordingly, the user can selectively change the transparency of a partial area on the screen information output based on the touch input.

FIGS. 7A to 7C are conceptual diagrams for explaining a control method for executing a function based on the angle change of the first and second body portions. FIG.

For example, the first screen information 310 may correspond to a home screen page including a plurality of icons to control the execution of an application.

According to the present embodiment, it is not necessary to output the graphic image receiving the touch input together with other screen information to output the home screen page. Accordingly, the screen information can be outputted using a wider area on the display unit 1510. [

The controller 1800 may change the third screen information 330 to the second screen information 320 on the second display area 1510b based on the touch input applied to the home screen page, Lt; RTI ID = 0.0 > 1510 < / RTI > The first screen information 310 may continuously be output on the first display area 1510a while the third screen information 330 is output.

The control unit 1800 controls the display unit 1510 to output the related screen 321 related to the second screen information 320 to the first display area 1510a when the first screen information 320 is switched to the first state can do. For example, when the home screen page is output on the first display area 1510a, the controller 1800 displays screen information to be output to the second display area 1510b And may control the display unit 1510 to output an associated image.

Accordingly, the user can receive desired information more quickly by applying an external force to the first and second body parts 1010 and 1020.

7B, the controller 1800 controls the display unit 1510 to switch the fourth screen information 340 to the third screen information 330 based on a touch input applied on the display unit 1510. [ Lt; / RTI > In the first state, the display unit 1510 selectively outputs an execution screen of an application to be executed.

When the first and second body parts 1010 and 1020 are folded so as to have a reference angle, the controller 1800 may divide the third and fourth screen information 330 and 340 into the second and first display areas 330 and 340, (1510b, 1510a). That is, the controller 1800 can display two pieces of screen information among the execution screens of the application that has been executed recently in the first and second display areas 1510a and 1510b.

That is, the control unit 1800 may control the display unit 1510 to output an execution screen of an executed or running application.

However, the present invention is not limited thereto. The control unit 1800 controls the display unit 1510 to output two preset screen information when the first and second body units 1010 and 1020 are folded to have the reference angle in the first state . For example, the two predetermined screens may correspond to an execution screen of an application designated by a user or designated as a frequently used application.

Accordingly, the user can receive the desired screen information more quickly through the gesture of folding the body part.

Referring to FIG. 7C, when the first and second body portions 1010 and 1020 are folded to have a reference angle, the transparency of the first screen information 310 output to the first display region 1510a is increased .

The controller 1800 selects the first image 310a included in the first screen information 310 based on the front touch applied to the display unit. The control unit 1800 may control the display unit 1510 to change the transparency of the first image 310a when the first image 310a is selected. For example, when a front touch is applied to the display unit 1510, one area of the first screen information may be opaque.

Meanwhile, when the first image 310a is selected, the second screen information 320, which is an execution screen related to the first image 310a, is output on the second display area 1510a.

According to the present embodiment, even when the first and second body portions 1010 and 1020 are folded to have a reference angle, not only the touch input sensed by the touch sensing portion 1011, It is possible to control the mobile terminal by an applied front touch.

8A and 8B are conceptual diagrams for explaining a control method of the display unit 1510 based on the double-sided touch input.

8A shows a case where a front touch applied to the display unit 1510 and a touch input applied to the touch sensing unit 1011 are detected together when the first state is changed to the second state And FIG. 8 (b) shows a case where at least one of the front touch and the touch input is not detected.

Referring to FIG. 8A, the controller 1800 controls the display unit 1510 to display the third screen information 330 in the second state. For example, the controller 1800 may change the first display area 1510a to be transparent and output the third screen information 330 on the second display area 1510b, Can be controlled. Alternatively, the control unit 1800 may control the display unit 1510 so that the first display area 1510a inverts the third screen information 330 and outputs the second screen information 320, can do.

Referring to FIG. 8 (b), the controller 1800 controls the display unit 1510 to output the second screen information 320 in the second state. That is, the controller 1800 controls the display unit 1510 to increase transparency without outputting an image to the first display area 1510a.

According to the present embodiment, the user can receive various types of images by applying touch input to the display unit 1510 and the body unit while changing the state of the body unit.

Referring to FIG. 8B, a control method of imaging the screen information on the display unit 1510 based on the touch input by the front touch and touch sensing unit 1011 will be described. The first display area 1510a outputs the third screen information 330 and the second display area 1510b outputs the second screen information 320. [

In FIG. 8B, the front touch and the touch input by the touch sensing unit 1011 are shown in the first state, but the present invention is not limited thereto. For example, the first and second body portions 1010 and 1020 may be configured to receive the touch input and capture and store the screen information only when the first and second body portions 1010 and 1020 are folded to form a reference angle.

FIGS. 9A to 9D are conceptual diagrams for explaining a control method of controlling transparency of screen information output to the display unit 1510. FIG.

Referring to FIG. 9A, in the first state, the second display area 1510b outputs the second screen information 320, and no image is displayed in the first display area 1510a. If the display unit 1510 is switched to the inactive state after the transition from the first state to the second state and a predetermined time passes, no voltage is applied to the polymer dispersed liquid crystal layer in the inactive state, Type liquid crystal layer is formed is switched to an opaque region. Accordingly, the second display information area 320 can not be identified by the first display area 1510a that is switched to the opaque area.

The controller 1800 controls the display unit 1510 based on a continuous touch input (for example, a dragging-type touch input) applied in a diagonal direction from one corner of the first body unit 1010.
