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 or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in an inner region of the mobile terminal covered by the touch screen described above or near the touch screen.

Examples of the proximity sensor 141 include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object by the change of the electric field according to the proximity of the conductive object. 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, an action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching an object on a screen is called a "contact touch." The position at which the object is in close proximity touch on the touch screen means a position where the object is perpendicular to the touch screen when the object is in close proximity touch. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, and a proximity touch movement state). have. Meanwhile, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern detected 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. Further, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) according to whether the touch on the same point on the touch screen is a proximity touch or a touch touch. .

As an example, the touch sensor may be configured to convert a change in pressure applied to a specific portion of the touch screen or capacitance generated at the specific portion into an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the touch, a capacitance at the touch, and the like, when the touch object applying the touch on the touch screen is touched on the touch sensor. Here, the touch object is an object applying a touch to the touch sensor and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

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

Meanwhile, the controller 180 may perform different control or perform the same control according to the type of touch object that touches the touch screen (or a touch key provided in addition to the touch screen). Whether to perform different control or the same control according to the type of touch object may be determined according to the operation state of the mobile terminal 100 or an application program being executed.

The ultrasonic sensor may recognize location information of a sensing object using ultrasonic waves. On the other hand, the controller 180 can calculate the position of the wave generation source through the information detected from the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time when the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generation source may be calculated using a time difference from the time when the ultrasonic wave reaches the light as the reference signal.

On the other hand, the camera 121, which has been described as the configuration of the input unit 120, includes at least one of a camera sensor (eg, CCD, 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 detect a touch of a sensing object with respect to a 3D stereoscopic image. The photo sensor may be stacked on the display element, which is configured to scan the movement of the sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column and scans contents mounted on the photo sensor by using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of light change, and thus, the position information of the sensing object can be obtained.

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 in the mobile terminal 100 or user interface (UI) and graphical user interface (GUI) information according to the execution screen information. .

The sound output unit 152 may include a receiver, a speaker, a buzzer, and the like.

The haptic module 153 generates various haptic effects that a user can feel. A representative example of the tactile effect generated by the haptic module 153 may be vibration. The intensity and pattern of vibration generated by the haptic module 153 may be controlled by the user's selection or the setting of the controller. For example, the haptic module 153 may synthesize different vibrations and output or sequentially output them.

In addition to vibration, the haptic module 153 may be used to stimulate pins that vertically move with respect to the contact skin surface, jetting force or suction force of air through the jetting or suction port, grazing to the skin surface, contact of electrodes, and electrostatic force. Various tactile effects can be generated, such as effects by the endothermic and the reproduction of a sense of cold using the elements capable of endotherm or heat generation.

The haptic module 153 may not only deliver a tactile effect through direct contact, but also may allow a user to feel the tactile effect through a muscle sense such as a finger or an arm. Two or more haptic modules 153 may be provided according to a configuration aspect of the mobile terminal 100.

Through this, a configuration without a front input unit in the front of the terminal is also possible. That is, the first area A may be the only input unit located in front of the terminal.

Referring to FIG. 3, a camera module 121b may be additionally mounted on the rear of the terminal body, that is, the rear case 102. The camera module 121b has a photographing direction substantially opposite to the camera 121a (see FIG. 2) and may be a camera having different pixels from the camera module 121a (see FIG. 2).

For example, the camera module 121a (refer to FIG. 2) has a low pixel so that the user's face is photographed and transmitted to the counterpart in case of a video call, and the camera module 121b immediately photographs a general subject. It is preferable to have a high pixel because it is not transmitted in many cases. The

camera modules

121a and 121b may be installed in the terminal body to be rotatable or pop-up.

A flash and a mirror may be additionally disposed adjacent to the camera module 121b. The flash shines toward the subject when the subject is photographed by the camera module 121b. The mirror allows the user to see his / her own face or the like when photographing (self-photographing) the user using the camera module 121b.

A sound output unit (not shown) may be further disposed on the rear side of the terminal body. The sound output unit at the rear side may implement a stereo function together with the sound output unit 152 (see FIG. 1) at the front side, and may be used for implementing the speakerphone mode during a call.

That is, along with the sound output unit 152 (first sound output unit) on the front of the terminal consisting of the receiver, the second sound output unit consisting of the rear or the speaker may be formed. However, the present invention is not limited thereto, and the second sound output unit may be provided at the side of the terminal.

The terminal body is equipped with a power supply unit (not shown) for supplying power to the portable terminal 100. The power supply unit may be built in the terminal body or may be configured to be directly detachable from the outside of the terminal body.

According to the illustration, the rear input unit 132 may be disposed on the rear of the terminal body. The rear input unit 132 may be, for example, located under the camera module 121b.

The rear input unit 132 is manipulated to receive a command for controlling the operation of the mobile terminal 100, and the input content may be variously set. For example, input commands such as power on / off, start, end, scroll, etc., adjust the volume of sound output from the sound output unit 152, or switch to the touch recognition mode of the display module 151. I can receive it. However, the present invention is not necessarily limited thereto, and the terminal may include only one of the front input unit and the rear input unit 132.

third display units

151b and 151c on the side surface may be provided.

5C may be the same as the case where the bezel area disappears in the structure of the mobile terminal described with reference to FIGS. 2 to 4. The display unit 151 may be a flexible display that can be bent to a certain degree. Therefore, the boundary between the first display unit 151a and the second and / or

third display units

151b and 151c may be curved with a constant rotation radius according to the bending characteristic of the display.

In the above, the schematic structure of the mobile terminal for implementing the control method of the mobile terminal according to an embodiment of the present invention has been described.

That is, FIGS. 2 to 5 extend the display unit (touch screen) provided on the front of the body to the side, but in the case of FIGS. 2 to 4, the bezel area is provided at the side end of the extended touch screen. Yes. In addition, Figure 5 is a structure that can extend the side of the touch screen on the front of the body through the material that can be bent at 90 ° without the side bezel. Accordingly, when the mobile terminal 100 and the external terminal contact through the side, the touch screen of the two terminals can be used as a single touch screen more naturally and easily through the side display of the two terminals.

Using the above-described hardware features of the mobile terminal, the mobile terminal according to an embodiment of the present invention displays predetermined information on the side display unit, as described below, and manipulates the side display unit. Through the operation of the mobile terminal can be controlled.

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

As described above, the mobile terminal according to the exemplary embodiment of the present invention may have a front surface of the display unit as a touch screen area. That is, the bezel area is present only in a portion of the top and bottom of the front body, and is not present in the bezel area on the side of the front body. Therefore, when the side surfaces of the first mobile terminal and the second mobile terminal are in contact with each other, the first battery screen of the first mobile terminal and the second touch screen of the second mobile terminal may be used as one large screen touch screen.

6 is a flowchart illustrating a method for controlling a mobile terminal according to an embodiment of the present invention. FIGS. 7 to 8 are diagrams for describing an exemplary embodiment shown in FIG. 6.

The control method of the mobile terminal according to an embodiment of the present invention may be implemented in the mobile terminal 100 described with reference to FIGS. 1 to 5. Hereinafter, a method of controlling a mobile terminal and an operation of the mobile terminal 100 for implementing the same will be described in detail with reference to the accompanying drawings.

Referring to FIG. 6, the controller 180 can drive a camera (S100).

The camera may be a first camera provided on one surface of the body of the mobile terminal 100. The first camera may be provided on the rear of the body.

The mobile terminal 100 may include a body and a first touch screen 151a of FIG. 5 provided at the front of the body. In addition, the mobile terminal may include a second touch screen (151b of FIG. 5) formed to extend from the first touch screen 151a to at least one side of the body. The second touch screen 151b may also be referred to as a side display.

When the user wants to capture an image through the first camera (121b of FIG. 4) provided at the rear of the body, the user may preview the image obtained through the first camera 121b on the front of the body. Displayed on the touch screen 151a, the user can take a picture while checking the preview image.

However, the user may not be able to check the preview image displayed on the first touch screen 151a while executing the camera function. For example, when the height of the mobile terminal 100 is located above the eyes of the user or when the front first touch screen 151a of the mobile terminal 100 covers a predetermined structure, the user cannot directly check the preview image. There is. In this case, there may be a problem that the image should be taken in a state where the preview image of the user cannot be confirmed.

Accordingly, the mobile terminal 100 according to an embodiment of the present invention may provide a preview image on the side display (first touch screen 151a), and more conveniently capture an image through a user operation on the side display. Make sure

The controller 180 can display a control area for controlling preview image and image capture on the first touch screen 151a (S110).

Even if the first touch screen 151a provided on the front surface of the mobile terminal 100 does not exist in the user's field of view, the controller 180 may be located in the control area provided in the second touch screen 151b provided on the side surface. An image may be photographed based on the input (S120).

Hereinafter, a method of capturing an image using the side display will be described in more detail with reference to FIGS. 7 to 8.

Referring to FIG. 7, the controller 180 of the mobile terminal 100 may display at least one application on the first touch screen 151a. The at least one application may comprise a camera application.

As the camera application is selected, the controller 180 drives the first camera (121a of FIG. 3) provided at the rear of the body of the mobile terminal 100.

As the first camera is driven, the controller 180 displays the preview image 11 acquired through the first camera on the first touch screen 151a.

In addition, the controller 180 may display a control area for controlling the image capturing on the second touch screen 151b. The second touch screen 151b is configured to display a first area (shooting button 12) for photographing the preview image 11 and a second image displayed by resizing the preview image 11 displayed on the first touch screen 151a. It may include an area (preview image) 13 or a third area 14 displaying a recently photographed image.

Here, the first area 12 is an area provided with a photographing button. When the touch input for the first area is received, the controller 180 may perform a capture operation.

On the other hand, when receiving a long touch input for the first area, it is possible to switch to the video mode instead of capturing still images to start capturing video.

The second area 13 is an area for providing a preview obtained through the first camera 121b provided on the rear surface, and the user can check the state of the current preview image in real time through the second area 13. have.

Meanwhile, the first region 12 and the second region 13 may be associated with each other to execute a predetermined function. By operating the first region 12, the size of the preview image displayed on the second region 13 may be enlarged or reduced.

The second touch screen 151b may be displayed on a predetermined background screen before the camera is driven so that a control area related to the camera may be displayed.

For example, as the first camera 151a is driven while the second touch screen 151b is in the display off state, the second touch screen 151b may be activated. Here, activation of the second touch screen 151b may mean that the display off state is switched to the on state. That is, the controller 180 may display on only when it is determined that the second touch screen 151b needs to be used to efficiently use power consumption.

Referring to FIG. 8, when a touch input to the first area 12 is received, a third area for capturing an image corresponding to the preview image 11 and displaying a recently captured image of the captured image ( 141). Accordingly, in a situation where the user cannot see the first touch screen 151a on the front side, the user may more conveniently capture an image using the second touch screen 151b on the side surface.

Meanwhile, according to an embodiment of the present invention, when the user can check the preview image through the first touch screen 151a when the camera is executed, it is necessary to utilize the second touch screen 151b on the side. This decreases. Accordingly, in an exemplary embodiment of the present invention, when it is difficult for a user to check the preview image through the first touch screen 151a, it may be preferable to use the side display.

Referring to FIG. 9, as the first camera 121b of FIG. 3 is executed at the rear of the body, the mobile terminal 100 may execute the second camera 121a provided at the front of the body. The user image 21 acquired by the second camera 121a may be displayed on the first touch screen 151a.

The controller 180 monitors a user capturing an image through the second camera 121a provided at the front of the body, and when the user disappears from the angle of view range of the second camera 121a, the second touch screen. 151b may be activated.

If it is determined that the user capturing the image disappears from the second camera 121a, the controller 180 switches the second touch screen 151b in the display off state to the display on state, and the first camera. The preview image 11 acquired through 121b may be resized (reduced) 13 and displayed on the second touch screen 151b.

As described with reference to FIG. 9, when the face of the user disappears from the second camera 121a provided at the front of the mobile terminal 100, the height of the gaze of the user is increased as shown in FIG. 10. This may be the case in which the second touch screen 151b is located.

Accordingly, the mobile terminal 100 can take an image in a top view through the first camera 121b provided at the rear of the body while maintaining a horizontal state with the ground.

Referring to FIG. 11, the mobile terminal 100 may drive the first camera 121b and display the preview image 11 on the first touch screen 151a. At this time, the second touch screen 151b on the side may be in a display off state. In addition, the display of the second touch screen 151b may be in an on state, but the preview image and the control area may not be displayed.

When the controller 180 receives the long touch input with respect to the second touch screen 151b of the side surface, the controller 180 removes the first region 12 for capturing the image and the second region 13 for displaying the preview image. 2 can be displayed on the touch screen (151b).

Referring to FIG. 12, the mobile terminal 100 may drive the first camera 121b and display the preview image 11 on the first touch screen 151a.

When the controller 180 receives an input for extending the touch to the second touch screen 151b while touching the preview image 11 displayed on the first touch screen 151a, the first touch screen The first region 12 and the preview image region 13 for capturing the preview image 11 displayed on 151a may be displayed on the second touch screen 151b.

In the above embodiment, the preview image obtained through the camera is displayed on the first touch screen 151a, and the photographing button and the preview image are resized to separately display the second touch screen 151b on the side. Explained them. However, the present invention is not limited thereto. For example, an image may be captured using only the side display while the front touch screen 151a is not activated.

13 to 14, the front first touch screen 151a of the mobile terminal 100 may be in a display off state. The display off state may be a case where the display is turned on automatically when a predetermined time elapses without any input while the display is on. In this state, an input of dragging the second touch screen 151b on the side surface in a predetermined direction may be received. The drag input may be present in the second touch screen 151b in a display on state or may be input in a display off state.

When the drag input for the second touch screen 151b is received, the controller 180 can display at least one application on the second touch screen 151b. The at least one application may include a camera application, and the first touch screen 151a may maintain the display off state even when the second touch screen 151b is activated. Accordingly, when the user wants to use the side display in capturing an image, the user may drive the camera using only the side display and capture the image using the preview provided on the side display, without activating the front display. . This can improve efficiency even in terms of power consumption.

On the other hand, the mobile terminal 100 according to an embodiment of the present invention does not always provide a preview image on the side display when driving the camera. In particular, even if the front touch screen disappears from the user's field of view, when the mobile terminal 100 is in a position close to the user, the user can often take an image by simply operating the front touch screen. However, when the mobile terminal 100 moves away from the user while the front touch screen disappears from the user's field of view, the user cannot see the front touch screen 151 and it is difficult to take an image by manipulating the front touch screen. There can be.

Referring to FIG. 15, when the mobile terminal 100 is located within a predetermined distance of the user while the camera is driven and the preview image is displayed on the front first touch screen 151a, the controller 180 may move to the side surface. The second touch screen 151b may not be activated. When the mobile terminal 100 is separated from the user by more than a predetermined distance, the controller 180 may separate the preview image area 13 and the button area 12 for capturing an image from the second touch screen 151b. ) Can be displayed.

That is, according to one embodiment of the present invention, when the distance between the user and the mobile terminal 100 is far from the second touch screen 151b, the necessity may be increased, thereby using a camera application. In this case, it may be determined whether to use the side display according to the distance between the user and the mobile terminal 100.

In the above embodiment, it has been seen that the image capturing can be efficiently performed by displaying the preview image and the image capturing button for driving the camera and capturing the image through the camera. Hereinafter, as the camera is driven, examples of controlling image capturing through various inputs to the control region will be described with various control regions used for capturing images displayed on the side display.

Referring to FIG. 16, when the controller 180 receives a touch input with respect to the preview image area 13 displayed on the second touch screen 151b of the side surface, the controller 180 may set a point where the touch input is received as a focus. . In addition, the guide FG for the point set as the focal point may be displayed.

Referring to FIG. 17, when the controller 180 receives an input of dragging in the first direction with respect to the first area 12 corresponding to the image capturing button displayed on the second touch screen 151b, the preview image is displayed. The preview image displayed in the area 13 may be zoomed in. In addition, when an input of dragging in a direction opposite to the first direction is received, the preview image may be zoomed out.

Referring to FIG. 18, when a predetermined input is received for the first area 12 corresponding to the image capturing button displayed on the second touch screen 151b, the controller 180 may switch to the video capturing mode. Can be. The predetermined input may be a long touch input to the first area 12.

When the long touch input to the first area 12 is received, video recording may be performed. In the meantime, when the user enters the moving picture shooting mode, an indicator indicating that the moving picture is being taken may be displayed together on the second touch screen 151b.

Referring to FIG. 19, the controller 180 may display a third region 14 displaying a recently photographed image on the second touch screen 151b of the side surface. When the controller 180 receives a touch input to the third area 14, the controller 180 displays a recently photographed image 15 displayed on the third area 141 on the first touch screen 151a. can do.

Meanwhile, referring to FIG. 20, when the controller 180 receives a predetermined touch input with respect to the third region 14 displayed on the second touch screen 151b on the side surface, the controller 180 is photographed through a camera to date and stores the memory. At least one image (I1, I2, I3, I4) stored in the display may be displayed on the second touch screen 151b.

The controller 180 displays the first region 12, the preview image region 13, and the recently photographed image region 14 corresponding to the image capturing button on the second touch screen 151b on the side surface. When a touch input is received with respect to an arbitrary point of the first touch screen 151a on the front surface, an image may be captured.

Meanwhile, as illustrated in FIG. 21, even when the first region 12, the second region 13, and the third region 14 are displayed on the second touch screen 151b of the side surface, the first front surface of the second touch screen 151b is displayed. 1 The soft button 31 'for capturing an image may be displayed on the touch screen 151a. In a state where the user is holding the mobile terminal 100 with one hand, the user may be positioned at an arbitrary point on the upper part of the first touch screen 151a with a specific finger. The controller 180 may determine a position on the first touch screen 151a indicated by the specific finger based on the sensing signal of the proximity sensor 141 of FIG. 1. As a result of the determination, the controller 180 may move and display the soft button 31 'for capturing the image to a position on the first touch screen 151a indicated by the specific finger. Accordingly, the user may capture an image based on a touch input to the soft button 31 whose position is moved without looking at the first touch screen 151a on the front side.

The captured image may be displayed on the third area 14 of the second touch screen 151b.

Referring to FIG. 22, the controller 180 is driven by a camera, and at least one control region necessary for capturing an image including the preview image region 13 is displayed on the second touch screen 151b. When an input for the home button provided on the front of the body is received, the control areas displayed on the second touch screen 151b may be removed.

In addition, for example, the second touch screen 151b may include a separate soft button 17 for removing the control areas, and the second touch is based on an input to the soft button 17. The control area displayed on the screen 151b may be removed.

As the control area is removed, a background screen displayed on the first touch screen 151a may extend to the second touch screen 151b.

Referring to FIG. 23, the mobile terminal 100 may detect a degree of inclination of the terminal through a gyro sensor. For example, when the camera is driven and the preview image is displayed on the first touch screen 151a in front, the second touch screen 151b on the side is inclined to be visible to the user. By detecting the tilt of the terminal, the preview image area 13 may be displayed on the second touch screen 151b of the side surface.

Meanwhile, the mobile terminal 100 may allow the mobile terminal 100 to be positioned inside the structure S while driving a camera in order to photograph a predetermined structure S. In this case, it may be difficult for the user to directly check the preview image displayed on the first touch screen 151a by covering the structure S. In this case, the mobile terminal 100 activates the second touch screen 151b on the side of the mobile terminal 100 based on the sensing signal of the illumination sensor 142 provided on the front surface, and moves the preview image area 13 to the second touch screen ( 151b). Accordingly, the user can easily capture an image even when the user's field of view is limited by using the side display and the illumination sensor.

As described above, the embodiments of the present invention may be independently implemented or at least one embodiment may be implemented in combination with each other.

The present invention described above can be embodied as computer readable codes on a medium in which a program is recorded. The computer-readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable media include hard disk drives (HDDs), solid state disks (SSDs), silicon disk drives (SDDs), ROMs, RAMs, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, and the like.
