Meanwhile, the sensing unit 140 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 180 may control the driving or operation of the mobile terminal 100 or may perform data processing, function or operation related to the application program installed in the mobile terminal 100 based on the sensing signal. Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.
First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.
Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.
On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .
The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, 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 the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.
On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.
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 151. [ 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 151 is activated or not. That is, the touch sensor can detect the touch input applied to the touch sensor with different activation periods depending on whether the display unit 151 is activated or not.
For example, in a state in which the display unit 151 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 151 is activated, the touch sensor can be always operated in an 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 151 is in an active mode (hereinafter referred to as an 'active mode'), the touch sensor continues to be in an active state and can wait for the touch input to the display unit 151 have. Alternatively, when the display unit 151 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 151 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 151 may be slowed down.
Therefore, the specific period can be set so as to increase the efficiency of power consumption while sensing the touch input that hits the display unit 151, 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).
Meanwhile, during the activated state of the display unit 151, 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 151 is inactivated. That is, the touch sensor can be activated at different periods depending on whether the display unit 151 is activated or not.
On the other hand, in the doze mode in which the display unit 151 is inactivated and the touch sensor is periodically activated, a predetermined touch input by the touch sensor (for example, The controller 180 may switch the doze mode to an active mode in which the display unit 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 151. [ For example, when the display unit 151 is in the closed state, the doze mode is executed, and when the display unit 151 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. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.
The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.
The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.
Meanwhile, the camera 121 includes at least one of a first camera 121a formed on the front surface of the mobile terminal body and a second camera 121b formed on the rear surface.

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.
Referring to FIGS. 2A and 2B, the mobile terminal 100 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 100 as at least one aggregate. Alternatively, the body of the mobile terminal may be referred to as the body.
The mobile terminal 100 includes a case (for example, a frame, a housing, a cover, and the like) that forms an appearance. As shown, the mobile terminal 100 may include a case 101, and the case 101 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 101 may be configured to be deformable together with the display unit 151 that is flexible by an external force in consideration of the characteristics of the flexible display unit 151. [ That is, the flexible display unit 151 is formed to be bent or folded together with the case 101.
For example, the case 101 may be formed of plastic, thin glass, a fiber component, 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 101 may be formed of a dielectric material or a low conductive material, and at least a part of the structure constituting the case 101 or the case 101 may be formed of a metal element.
A display unit 151 is disposed on a front surface of the body of the mobile terminal to output information. As shown in the figure, the display unit 151 may be mounted on the case 101 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 121 or the sound output unit 152 to the outside.
The mobile terminal 100 may be configured such that one case provides the internal space, unlike the above example in which a plurality of cases provide an internal space for accommodating various electronic components. In this case, a universal mobile terminal 100 in which a synthetic resin or metal is connected from the side to the rear side can be realized.
Meanwhile, the mobile terminal 100 may include a waterproof portion (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 151 and the front case, between the front case and the rear case, or between the rear case and the rear cover, and seals the internal space when the front and rear cases are engaged.
The mobile terminal 100 may include a display unit 151, an audio output unit 152, a light output unit 154, a second camera 121, a microphone 122, and the like.
2A and 2B, a display unit 151 is disposed on a front surface of a body of the mobile terminal, and a camera 121, an audio output unit 152, a microphone (122), and a rear input unit (123a, 123b). The mobile terminal 100 in which the optical output unit 154 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, the display unit 151 may be disposed on the front surface of the mobile terminal 100. The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .
The display unit 151 may be 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 151 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 unit 151. The deformable display unit 151 may be referred to as a 'flexible display unit' or a 'ben double display unit'. Here, the flexible display unit may include both a general flexible display and an electronic paper (e-paper) and a combination thereof. That is, the flexible display unit 151 refers to a display unit 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 unit 151 is not deformed (for example, in a state of having an infinite radius of curvature), the display area of the flexible display unit 151 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 unit 151 may be placed in a bent state (e.g., a state in which the flexible display unit 151 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 unit 151, the flexible display unit 151 can be deformed into a flat state (or a less bent state) or a more bent state.
The flexible display unit 151 may be formed of a plurality of layers of materials. For example, 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 control unit 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.
In this way, the flexible display unit 151 can form a flexible touch screen together with the touch sensor. In this case, the touch screen can function as the user input unit 123 (see FIG. 1).
On the other hand, the state change of the flexible display unit 151 is not limited to the external force. For example, when the flexible display unit 151 is in a non-deformed state, it may be transformed into a deformed state by a command of a user or an application. More specifically, the mobile terminal 100 may include a driving unit (not shown). If the predetermined condition is satisfied, the mobile terminal 100 may be transformed into a deformed state without being deformed due to driving of the driving unit.
The mobile terminal 100 according to an exemplary embodiment of the present invention may include a deformation sensing unit that can sense a deformation of the flexible display unit 151. [ The deformation detecting means may be included in the sensing unit 140 (see FIG. 1).
The deformation detecting means may be provided in the flexible display unit 151 or the case 101 to sense information related to the deformation of the flexible display unit 151. Here, the information related to the deformation may be the direction in which the flexible display unit 151 is deformed, the degree of deformation, the deformation position, the deformation time, and the acceleration at which the deformable flexible display unit 151 is restored, In addition, the information can be various information that can be detected due to warping of the flexible display unit 151.
The control unit 180 may change the information displayed on the flexible display unit 151 based on the information related to the deformation of the flexible display unit 151 sensed by the deformation sensing unit, It is possible to generate a control signal for controlling the function of the controller.
For example, when the flexible display unit 151 is bent in response to an external physical force, the control unit 180 controls the flexible display unit 151 in accordance with the bent direction of the flexible display unit 151, the bent angle, The screen image previously displayed on the display unit 151 can be rearranged, separated, synthesized, or changed. More specifically, when the flexible display unit 151 is bent inward by the external force, the control unit 180 can display the screen images displayed on the flexible display unit 151 to be close to each other. On the contrary, when the flexible display unit 151 is bent outward by the external physical force, the screen images displayed on the flexible display unit 151 can be displayed to be spaced apart from each other.
Meanwhile, the mobile terminal 100 according to the present modification may include a case for accommodating the flexible display unit 151. The case 101 may be configured to be deformable together with the flexible display unit 151 by an external force in consideration of the characteristics of the flexible display unit 151. [ That is, the flexible display unit 151 is formed to be bent together with the case 101.
For example, the case 101 may be formed of plastic, thin glass, a fiber component, 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 101 may be formed of a dielectric material or a low conductive material, and at least a part of the structure constituting the case 101 or the case 101 may be formed of a metal element.

The rear input units 123a and 123b are operated to receive a command for controlling the operation of the mobile terminal 100, and input contents can be variously set. For example, a command such as a command such as power on / off, start, end, scrolling and the like, adjustment of the size of sound output from the sound output unit 152, switching to the touch recognition mode of the display unit 151, Can receive. The rear input unit may be implemented as a touch input, a push input, or a combination thereof.
The rear input units 123a and 123b may be disposed so as to overlap the front display unit 151 in the thickness direction of the mobile terminal body. The rear input units 123a and 123b may be disposed at positions adjacent to both the left and right ends of the case 101. [ The rear input units 123a and 123b are positioned on the rear surface of the mobile terminal 100 when the case 101 is not bent and are bent when the left and right ends of the case 101 are opposed to each other. 100, respectively. 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 100 may be provided with a fingerprint recognition sensor for recognizing the fingerprint of the user, and the controller 180 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 151 or the user input units 123a and 123b.
The microphone 122 is configured to receive the user's voice, other sounds, and the like. The microphone 122 may be provided at a plurality of locations to receive stereophonic sound.
A rear camera 121b may be disposed on the rear surface of the portable device body. Although not shown in the drawing, when the front camera 121a is disposed on the front surface of the body of the mobile terminal, the rear camera 121b has a photographing direction substantially opposite to the front camera 121a.
The front camera 121a may be disposed in an opening formed in a part of the flexible display unit 151. [ Alternatively, the front camera 121a may be disposed in an opening formed in a part of the case disposed on the front side.
The rear camera 121b processes a still image or a moving image frame obtained by the image sensor in the photographing mode or the video communication mode. The processed image frame can be displayed on the flexible display unit 151 and can be stored in the memory 170. [
The rear camera 121b may include 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 121 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 121b. The flash 124 illuminates the subject toward the subject when the subject is photographed by the rear camera 121b.
In addition, the electromagnetic wave generator 130 may be disposed adjacent to the rear camera 121b. The electromagnetic wave generator 130 emits the generated electromagnetic wave when the rear camera 121b 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, the antenna forming part of the broadcast receiving module 111 (see FIG. 1) may be configured to be able to be drawn out 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 optical output unit 154 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 180 may control the light output unit 154 to terminate the light output when the event confirmation of the user is detected.

One end of the first support link 310 may be connected to the upper edge 249 of the hinge 240 to implement the above structure. That is, the first connection protrusion 311 of the first support link 310 and the first connection groove 243 of the hinge unit 240 can be connected to each other at the upper part of the upper part and the lower part of the hinge part 240.
Here, the upper portion of the hinge portion 240 may mean an area adjacent to the flexible display 230 in the hinge portion 240 when the first and second bodies 210 and 220 are in the first state .
The folding area 233 of the flexible display 230 can be disposed on the hinge part 240 and the first and second supporting links 310 and 320 arranged on the same plane. That is, since the folding area 233 of the flexible display 230 is entirely supported by the hinge part 240 and the first and second supporting links 310 and 320, Even when the input is inputted, the flexible display 230 can be stably supported without flowing. Therefore, the whole area of the flexible display 230 can be utilized as a display area and a touch area without the need to form a bezel on the hinge part 240. [
4 and 8A, the first hole 212 may be formed along the thickness direction (z direction) of the body at the inner side of the body. Further, the lower side of the first hole 212 may be extended to an auxiliary hole formed along the longitudinal direction (x direction) of the body.
8A to 8C, one end of the first support member 310 and the other end of the second support member 320, which are connected to each other through the first hole 212, And may be moved along the thickness direction of the body when the state of the body 210 or 220 is changed.
4 and 8A, the second hole 213 may be formed along the longitudinal direction of the body at an inner surface of the body.
8A to 8C, the other end of the second support member 320, which is connected through the second hole 213, is connected to the first and second bodies 210 and 220, And may be moved along the longitudinal direction (y direction) of the body.
8A, in the first state, the other end of the first support member 310 and one end of the second support member 320 are positioned above the first hole 212. [ The other end of the second support member 320 is disposed outside the second hole 213.
Here, the outer side of the second hole 213 may mean a side relatively far from the hinge part 240 in the second hole 213. The inner side of the second hole 213 may mean a side relatively closer to the hinge portion 240 in the second hole 213.
8B shows the state of the support part 300 during the transition of the first and second bodies 210 and 220 from the first state to the second state. Referring to FIG. 3, the other end of the first support member 310 and one end of the second support member 320 may be moved to the lower side of the first hole 212. The other end of the second support member 320 may be moved to the inside of the second hole 213.
Referring to FIGS. 8A and 8B, when the first and second support members 310 and 320 form a square angle with each other in the first state, when the state starts to be changed, an angle (for example, an obtuse angle ).
Referring to FIG. 8C, the other end of the first support member 310 and one end of the second support member 320 may be caught in the auxiliary hole of the first hole 212. At this time, one surface of the first support member 310 and the hinge unit 240 may be arranged to intersect with each other. That is, one surface of the first support member 310 and the hinge unit 240 may be perpendicular to each other.
Referring to FIGS. 8C and 9B, in a second state, a space between the first and second bodies 210 and 220 is surrounded by the first and second support members 310 and 320 and the hinge part 240, (S) may be formed. That is, the folding area 233 of the display 230 can be received in the receiving space S in a folded state. That is, the accommodating space S can accommodate the folding area 233 in a state of better fitting with the folding area 233 of the display unit 230 forming the curvature.
4 and 9A, the inner surface 201 of the first and second bodies 210 and 220, which corresponds to the first support link 310, is formed parallel to the outer surface of the bodies, The inner surface 202 corresponding to the support link 320 may be formed to be inclined with respect to the outer surface of the bodies.
Here, the meaning of? Correspondence? Can be interpreted as meaning?
Referring to FIG. 9A, when the first and second bodies 210 and 220 are in the first state, the first and second support links 310 and 320 are separated from the inner surfaces 201 and 202 of the bodies As shown in FIG. In other words, in the first state, the first and second support links 310, 320 are spaced apart from the inner surfaces 201, 202 of the bodies to form flush surfaces with one surface 248 of the hinge portion 240 do.
9B, when the first and second bodies 210 and 220 are in the second state, the first and second support links 310 and 320 are formed in the shape of the inner surfaces 201 and 202 of the bodies As shown in Fig. That is, since the inner surfaces 201 and 202 of the body corresponding to the first and second support links 310 and 320 form a predetermined angle with respect to each other, the first and second support links 310 and 320 2 < / RTI > state.
That is, in the second state than in the first state, the first and second support members 310, 320 are disposed closer to the inner surfaces 201, 202 of the bodies.
Meanwhile, the folding area 233 of the display 230 forms a curved surface when folded. At this time, the first and second support links 310 and 320 and the hinge part 240 may be arranged to receive the curved surface more easily. Furthermore, it is possible to provide a foldable mobile terminal having a thinner thickness than when the support portion 300 is formed of only one support link.
