Also, the display unit 151 may be configured as a stereoscopic display unit 152 for displaying a stereoscopic image.

Here, a stereoscopic image represents a 3-dimensional stereoscopic image, and a 3-dimensional stereoscopic image represents a progressive depth and reality in which objects are located on a monitor or a screen. It is an image that makes you feel the same as reality space. 3D stereoscopic images are implemented using binocular disparity. The binocular parallax means the parallax caused by the positions of the two separated eyes. When the two eyes see different two-dimensional images and the images are transmitted to the brain through the retina and fused, the depth and real feeling of the stereoscopic image can be felt do.

On the other hand, when a display unit 151 and a sensor (hereinafter, referred to as 'touch sensor') that detects a touch operation form a mutual layer structure (hereinafter referred to as a 'touch screen' It can also be used as an input device in addition to the device. The touch sensor may have the form of, for example, a touch film, a touch sheet, a touch pad, or the like.

The touch sensor may be configured to convert a change in a pressure applied to a specific portion of the display unit 151 or a capacitance generated in a specific portion of the display unit 151 into an electrical input signal. The touch sensor can be configured to detect not only the position and area where the touch object is touched on the touch sensor but also the pressure at the time of touch. 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.

If 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.

Referring to FIG. 1, a proximity sensor 141 may be disposed in an inner region of the mobile terminal or in the vicinity of the touch screen, which is surrounded by the touch screen. The proximity sensor 141 may be provided as an example of the sensing unit 140. The proximity sensor 141 measures the presence or absence of an object approaching a predetermined sensing surface It refers to a sensor that uses infrared rays to detect without mechanical contact.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection fluorescent light sensor, a mirror reflection fluorescent light sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. When the touch screen is electrostatic, it is configured to detect the proximity of the pointer by a change of the electric field along the proximity of an object having conductivity (hereinafter, referred to as a pointer). In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Hereinafter, for convenience of explanation, the act of recognizing that the pointer is positioned on the touch screen while the pointer is not in contact with the touch screen is referred to as "proximity touch & The act of actually touching the pointer on the screen is called "contact touch. &Quot; The position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor 141 detects 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, a proximity touch movement state, and the like).

The proximity sensor 141 measures the distance between the sensing surface (for example, a user's finger or a stylus pen) to which the touch is applied without mechanical contact using the force of the electromagnetic field or infrared rays. The terminal recognizes which part of the stereoscopic image has been touched using the distance. In particular, when the touch screen is of the electrostatic type, the proximity of the sensing object is detected by a change of the electric field according to the proximity of the sensing object, and the touch on the three-dimensional is recognized using the proximity.

The stereoscopic touch sensing unit 142 senses the strength or duration of a touch applied to the touch screen. For example, the three-dimensional touch sensing unit 142 senses a pressure to apply a touch, and when the pressing force is strong, recognizes the touch as a touch to an object located further away from the touch screen toward the inside of the terminal.

The ultrasonic sensing unit 143 is configured to recognize the position information of the sensing target using ultrasonic waves.

The ultrasound sensing unit 143 may include, for example, an optical sensor and a plurality of ultrasound sensors. The light sensor is configured to sense light, and the ultrasonic sensor is configured to sense ultrasonic waves. Since light is much faster than ultrasonic waves, the time it takes for light to reach the optical sensor is much faster than the time it takes for the ultrasonic waves to reach the ultrasonic sensor. Therefore, it is possible to calculate the position of the wave generating source using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera sensing unit 144 includes at least one of a camera 121, a photo sensor, and a laser sensor.

For example, the camera 121 and the laser sensor are combined with each other to sense a touch of a sensing target with respect to a three-dimensional stereoscopic image. When the distance information detected by the laser sensor is added to the two-dimensional image photographed by the camera, three-dimensional information can be obtained.

As another example, a photosensor may be stacked on a display element. The photosensor is configured to scan the movement of the object 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 light change, thereby acquiring position information of the object to be sensed.

The cover may include a magnet portion 540 formed on the second member 520 and a magnetic member 540 on one side of the mobile terminal main body 540 corresponding to the magnet portion 540 in the closed state to detect a change in magnetism due to the movement of the magnet portion. And a sensor unit 550 (Hall sensor).

The control unit activates the display unit when it is switched from the closed state to the open state based on the magnetic change sensed by the hall sensor 550. [ Also, the display unit outputs predetermined screen information in the open state.

Hereinafter, the driving state of the mobile terminal in the open state according to various embodiments will be described.

FIG. 5 is a flowchart for explaining a control method of a mobile terminal mounted on a cover according to the present invention. FIG. 6A is a conceptual diagram for explaining the control method of FIG. 5 according to an embodiment.

The user switches the mobile terminal from the closed state in which the cover covers the display portion to the open state (S. Here, at least a part of the display portion is opened by the second member 520 of the cover to the outside It can be defined as exposed state.

The sensor unit senses a change in magnetism generated by the movement of the magnet unit based on the movement of the second member 520 (S502). The cover may include a plurality of magnets. The magnets may be spaced apart from each other. For example, the magnets may be disposed adjacent to each other in the second member 520, or may be disposed in one area of the first member 510.

And outputs screen information related to a predetermined application based on at least one magnetism change of the plurality of magnets on the display unit (S503).

Referring to FIGS. 6A and 6B, the display unit displays an application execution screen 610. The application may correspond to an application preset by the user.

For example, the control unit activates the display unit and executes a message application when the magnetic unit is switched to the open state by the magnetism change. Also, the control unit may control the display unit to output an execution screen 610 of the message application.

Referring to (a) and (c) of FIG. 6A, the display unit displays the restricted screen 620 on one side. Here, the limited screen 620 corresponds to an image including an icon of the at least one application so that at least one predetermined application can be executed. That is, a non-user of the mobile terminal can use a predetermined number of applications by applying a touch input to the icon.

The image may display information about the user of the mobile terminal and a phrase indicating that the use of the current mobile terminal is limited to some extent.

Although not shown in the figure, the controller may control the display unit to output a restricted screen for confirming that the user of the mobile terminal is a user. For example, the restriction canceling screen may include an input window for inputting a password, an image for inputting a set pattern, and the like.

That is, when the cover is opened by the cover, the controller may control the display unit to output the restricted screen 620 in order to secure information related to the user.

A control method for directly executing different applications in the open state will be described with reference to FIG. 6B.

Referring to FIGS. 6 (a) and 6 (b), the magnet portion 540 may include a plurality of magnets. For example, the magnet portion 540 includes first to third magnets 541, 542, and 543. One corner of the second member 520 is connected to the first member 510 through the connection part 530 and the magnet part 540 is formed at a corner opposite to the one corner. The first to third magnets 541, 542, and 543 are disposed apart from each other along the other corners.

The mobile terminal includes first to third hall sensors 551, 552 and 553 for detecting magnetic changes of the magnets in a region corresponding to the first to third magnets 541, 542 and 543.

The second member 520 may be formed of a material that can be partially bent by the pressure of the user applied to switch the closed state to the open state. Accordingly, a part of the corner is bent by the pressure of the user, and the magnetic changes generated by the first to third magnets 541, 542, and 543 can be sequentially generated. For example, when the second member 520 is moved by holding the edge of the region adjacent to the first magnet 541, the first Hall sensor 551 senses the magnetic change first, The sensor 553 detects the magnetic change at the latest.

The control unit controls the display unit to output screen information related to an application corresponding to a magnet (or hall sensor) whose magnetic change is first detected. Here, the application corresponding to the magnet can be preset by the user.

For example, when the area adjacent to the first magnet 541 is moved by a user's hand, the second member 520 moves while the first Hall sensor 551 detects the magnetic change first.

The control unit may execute the first application corresponding to the first magnet 541 and control the display unit to output the first execution screen 610 of the first application. As shown in the figure, the first application may correspond to a message application, but is not limited thereto and may be changed by a user.

Also, when the area adjacent to the third magnet 543 is moved first by the hand of the user, the second member 520 moves while the third hall sensor 553 detects the magnetic change first .

The control unit may control the display unit to execute a second application corresponding to the third magnet 543 and output a second execution screen 630. [ As shown in the figure, the second application may correspond to a gallery application.

With the mobile terminal according to the present invention, when the user switches to the open state by the cover, information on the application executed by the magnetism change caused by the magnet can be directly provided.

In addition, by holding the specific area of the cover and changing the open state, the user can activate the display unit and immediately execute the desired application, and receive the execution screen immediately.

Referring to FIG. 6C, a control method for activating an application related to an event in an open state when an event occurs will be described. The first member 510 of the cover according to the present embodiment includes an opening 521 formed to expose a part of the display unit in the closed state. Also, the cover according to the present embodiment includes the first to third magnets 541, 542, 543 and the first to third hall sensors 551, 552, 553.

When the event occurs in the closed state, the control unit controls the display unit to output the time information on the event to one area of the display unit corresponding to the opening unit 521.

Referring to FIGS. 6A and 6B, when the third hall sensor 553 detects the first magnetic change, the controller executes a second application corresponding to the third magnet 543 . Also, in the open state, the control unit controls the display unit to output the second execution screen 630 of the second application.

Meanwhile, if the second hall sensor 552 detects the first magnetic change while the display unit outputs information related to the event through the opening 521, the control unit executes the application related to the event.

For example, when the event corresponds to reception of a text message, the control unit executes the message application. In addition, the control unit controls the display unit to output a specific execution screen of the application including the received message. That is, the display unit outputs time information related to the event in an open state.

According to the present embodiment, when the event is received, the user can receive the time information on the event directly by switching to the open state by holding the predetermined position. In addition, the user can immediately execute another application even when the occurrence of the event is recognized.

7A to 7C are conceptual diagrams for explaining a control method of a mobile terminal using a magnet formed on a first member.

7A and 7B, a control method of canceling the lock mode using the fourth magnet 544 formed in the first member will be described. Referring to FIG. 7A, the fourth magnet 544 is formed in one area of the first member 510 surrounding the rear surface of the mobile terminal. The first member 510 includes a mounting space for the fourth magnet 544. The fourth magnet 544 is mounted movably in one direction in the mounting space. That is, the user can move the fourth magnet 544 by applying a force.

Also, although not shown in the drawing, the mobile terminal includes a fourth hall sensor (not shown) disposed in a region corresponding to the fourth magnet 544 of the main body. That is, the fourth hall sensor (not shown) senses a magnetic change due to the movement of the fourth magnet 544.

Referring to FIGS. 7A and 7B, when the second member 520 is moved from the closed state to the open state by the movement of the second member 520, the control unit activates the display unit and outputs the lock screen 640 can do. That is, if the control unit is set to switch from the closed state to the lock mode, the control unit controls the display unit to output the lock screen 640 in the open state.

The lock screen 640 includes a graphic image for receiving a touch input to release the lock mode. The control unit terminates the lock mode when a touch input suitable for the graphic image is received.

Referring to FIGS. 7B and 7C, the controller turns off the lock mode based on a user's input to the fourth magnet 544 when the lock screen is output.

In addition, when the lock mode is canceled, the controller may control the display unit to switch the lock screen 640 to the predetermined screen information 650. The screen information 650 is not limited to specific screen information. For example, it may correspond to screen information immediately before the display unit is switched to the inactive state, a home screen page including at least one icon, an image preset by the user, and the like.

Meanwhile, referring to FIG. 7B, the lock mode is turned off by the magnetism change caused by the fourth magnet 544. When the lock mode is canceled, the control unit executes a predetermined application. The control unit may control the display unit to switch the lock screen 640 to the execution screen 620 of the application.

According to the present embodiment, the user can more easily release the lock mode by using the magnet formed on the back surface of the mobile terminal.

Although not shown in FIGS. 7A and 7B, the control unit senses a magnetic change based on a magnet formed on the second member 520 when the closed state is switched to the open state. Accordingly, the control unit can immediately execute the application corresponding to the magnetic change. That is, the user can execute the application while switching to the open state, and the lock mode is canceled according to the magnetism change according to the fourth magnet, so that the user can receive the information about the desired application more quickly.

Referring to Fig. 7C, a control method for selectively executing an appropriate application using a camera will be described.

The controller activates the camera 121 based on the change in magnetism generated by the fourth magnet 544. The camera 121 may correspond to a camera mounted on a front surface or a rear surface of the mobile terminal. The controller 121 detects the external environment of the mobile terminal using the camera 121. For example, the control unit can recognize where the external environment is based on a logo or a barcode of a place photographed through the camera 121.

The control unit activates an application suitable for the external environment. For example, when the external environment corresponds to a cafe, an application related to a card, a discount card, and the like necessary for payment is executed. Also, the control unit controls the display unit to provide the summary information 661 related to the application through the opening 521. [ For example, in the case of a card storage application, the display unit may output a logo of the card.

The control unit controls the display unit to output the execution screen 660 of the application when the second member 520 is in the open state. In addition, the control unit controls the display unit to output screen information related to the external environment among the applications.

Although not shown in the figure, the controller may control the display unit to output summary information of another application related to the external environment when a touch input is applied to the display unit through the opening. Accordingly, the control unit can execute the other application.

The controller may control the display unit to output the main information of the application when the touch input is applied to the redirector for outputting the summary information 661 in the closed state. For example, if it is detected that the mobile terminal is located in the cafe through the camera 121, the control unit controls the display unit to output the logo of the cafe corresponding to the external environment through the opening 521. [ The control unit controls the display unit to switch the logo to a barcode and output the barcode when the touch input is applied to a display unit that outputs the logo of the cafe in the closed state. Accordingly, the user can use the virtual card of the cafe by using the barcode without switching the mobile terminal to the open state.

According to the present embodiment, the user can use the camera in the closed state to sense the external environment and execute the desired application more quickly.

8A to 8D are conceptual diagrams for explaining a control method for executing a predetermined application in a closed state based on a change in magnetism.

A control method for activating a voice recognition application using a magnetic change will be described with reference to FIG. The sensor unit 550 senses a change in magneticity of the magnet unit 540 during the transition from the closed state to the open state and then back to the closed state. The control unit executes a preset application (or a function) when a change in magnetism that is switched from the closed state to the open state and then from the closed state to the closed state is detected.

The control unit causes the predetermined application to be executed when the time until the state is restored to the closed state is shorter than the preset reference time. On the other hand, when the time until the restoration to the closed state is longer than the reference time, the control unit maintains the state when it is in the open state or switches the display unit to the inactive state according to the passage of time.

The application according to the present embodiment preferably includes a function that at least one of the sound output unit 153 and the microphone 122 is activated by execution of the application.

For example, the application may correspond to a speech recognition application. The voice recognition application drives at least one function of the mobile terminal based on voice information of a user input through the microphone 122. [ That is, the user can replace the control signal for driving the mobile terminal with the voice input, not the touch, on the display unit.

Also, when the voice recognition application is executed, the sound output unit 153 outputs a description of driving the voice recognition application and a driving state of the mobile terminal as auditory data.

Referring to (b) and (c) of FIG. 8A, the control unit executes the speech recognition application based on the magnetism change. When the speech recognition application is executed, the control unit activates the sound output unit 153 and the microphone 122. In the closed state of the cover, the control section controls the sound output section to output auditory data related to the speech recognition application.

The user can recognize that the speech recognition application has been executed through the auditory data.

A control method for terminating the application will be described with reference to FIG. The control unit may terminate the application based on a change in magnetism due to the movement of the magnet unit 540 while the application is being executed.

For example, when the second member 520 is switched from the open state to the closed state within the predetermined reference time, the control unit controls the application to be terminated in the closed state. In addition, the control unit controls the sound output unit 153 to output auditory data indicating that the application is terminated in the closed state.

However, if the application is not used for a predetermined time while the closed state is maintained (for example, there is no voice signal input to the microphone 122), the control unit may terminate the application.

The control unit may control the display unit to display an execution screen of the executed application when the control unit is switched to the open state.

Alternatively, the control unit may terminate the application based on the voice of the user applied to the microphone 122. [ For example, when the voice signal of a predetermined user is inputted to terminate the application, the control unit terminates the application.

Thereby, the user can execute the application in which the visual information is unnecessary in the closed state, and can easily end the application being executed by moving the second member.

Referring to FIG. 8C, a control method for executing a predetermined application will be described. When the sensor unit 550 senses the switch from the opened state to the closed state for the preset reference time, the controller executes the application set by the user. The preset application corresponds to a program in which auditory data is output by execution. For example, a music application, a video playback application. In addition, the controller may control the sound output unit 153 to directly output the auditory data set by the user based on the change in magnetism due to the movement of the second member 520.

In addition, the control unit terminates the running application when it is detected that the preset application is being executed and the transition from the open state to the closed state within the reference time is detected.

Accordingly, the user can easily execute the desired application without activating the display unit and applying the touch input to the display unit.

A control method of activating an application according to a received event will be described with reference to Fig. 8D. For example, when the mobile terminal receives a call in the closed state, the sound output unit 153 outputs a sound indicating the received call.

The control unit activates the call mode when the call is switched from the open state to the closed state within the reference time while the call is received. That is, the user can switch the mobile terminal to the call mode and receive the received call by opening and closing the second member 520.

Also, the user can make a call using the microphone 122 and the sound output unit 153 while the second member 520 is closed.

The event related to the received call has been described as an example, but the present invention is not limited thereto. For example, when an alarm is generated by a user and the alarm sound is output, the control unit may terminate the notification sound when the user switches from the open state to the closed state. In addition, the control unit may control the sound output unit 153 to convert the schedule into audio data and output the audio data.

Accordingly, the user can be informed of the event generated using the display unit, or can execute the application related to the received event in the closed state.

9 is a conceptual diagram for explaining a control method of adjusting the brightness of the display unit in the open state. The controller can determine the degree of movement of the second member 520 based on the change in magnetism of the magnet unit 540 detected by the sensor unit 550. [ That is, the controller can determine the exposure range of the display unit exposed by the second member 520 due to the magnetism change.

The controller may adjust the brightness of the display unit based on the exposure range. For example, the display unit darkly outputs a region much distant from the second member 520, and one region of the display unit adjacent to the region where the second member 520 and the first member 510 are connected Brightly.

Accordingly, the user can view the entire screen information output to the display unit, but it is difficult to identify the screen information to a person who is distant from the display unit due to the dark area. Thus, the user can more effectively prevent the information from being exposed to the other user while the second member is used to cover a part of the display unit.

10 is a conceptual diagram for explaining a control method of a mobile terminal mounted on a cover including a fingerprint recognition unit.

Referring to FIG. 10A, the second cover 520 further includes a fingerprint recognition unit 560 that recognizes a fingerprint when a user's hand touches the finger. The fingerprint recognition unit 560 is preferably formed at a position where a user's hand touches the second cover 520 to open the second cover 520. [ When the magnet part 540 includes a plurality of magnets, the fingerprint recognition part 560 may be disposed in an area adjacent to one of the plurality of magnets.

10 (a) and 10 (b), when the fingerprint of the user sensed by the fingerprint recognition unit 560 is substantially the same as the previously stored fingerprint, the controller cancels the lock mode, 650 of the display unit.

Referring to FIGS. 10A and 10B, when the fingerprint of the user detected by the fingerprint recognition unit 560 is different from the previously stored fingerprint, the control unit 620 outputs the restriction screen 620. That is, when the display unit is activated by a person other than the designated user, the restriction screen 620 is provided to protect the information of the designated user of the mobile terminal.

In addition, although not shown in the figure, when the magnetism change of the magnet spaced apart from the fingerprint recognition unit 560 occurs the fastest (in other words, the fingerprint is not recognized in the fingerprint recognition unit 560) The control unit may control the display unit to output the display unit.

Accordingly, the user can switch to the open state to activate the display unit, and at the same time, activate the mobile terminal in a usable form through the fingerprint recognition procedure.

The above-described mobile terminal and the mobile terminal equipped with the cover are not limited in configuration and method of the above-described embodiments, but the embodiments can be applied to all or a part of each embodiment May be selectively combined.
