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.

Touch can be sensed.

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.

Referring to FIG. 5B, a process of performing signal processing in the mobile terminal 100 when an input signal related to the screen control is received from the display device 200 will be described. First, the mobile terminal 100 and the video display device 200 detect a wireless connection for screen control through the Commection Managers 501a and 501b. At least one application is executed through the application manager 502a of the mobile terminal 100, and the UI manager 503b receives information about the executed application. The mobile terminal 100 provides a UI (User Interface) for the video display device 200 to the Miracast 504b of the video display device 200 through the Miracast 504a. Then, the Miracast 504b of the video display device 200 outputs the received screen and UI (User Interface) to the display. When the input signal inputted to the image display device 200 is detected through the input device control 505 of the image display device 200, the input event is transmitted to the mobile terminal 100, The mobile terminal 1000 converts the input event signal into a signal that can be operated when the mobile terminal 1000 is multi tasking and transmits the signal to the control unit of the mobile terminal 100 through the input event.

When the input signal related to the screen control is received, the control unit changes the application range of the device on which the screen control is performed based on the information related to the state of the terminal 100 and the state of the display device 200 or the user environment information At least one of the first mode and the second mode is selected (S440).

The information related to the state of the terminal 100 and the display device 200 includes information on the state of the terminal, for example, when an event is detected in the terminal (e.g., message reception, call signal reception, Power on of the terminal, power off, display awake key, etc.), a key press occurred in the image display device, and the like.

The user environment information includes information related to a user viewing the terminal 100 or a user viewing the video display device 200 (for example, whether the user is the user or not) Intention (whether to input text, whether to share the screen, switch the operation mode related to screen control, etc.).

The controller collects information related to various states and user environment information from the terminal and the image display device, and can automatically select, change, or cancel the operation mode related to the screen control. For example, based on a specific input, the control unit may determine whether the user intends to use the terminal and the video display device as the same input means or only the device to which the specific input is currently applied as the input means have. In addition, the control unit can trace and detect the information related to the status of both devices and the environment of the user, retrospectively for a predetermined period of time after the input signal is received.

Specifically, when the first mode is selected, the control unit simultaneously controls a first screen displayed on the display unit based on the received input signal and a second screen corresponding to the GUI displayed on the display apparatus S450). That is, in the first mode, the screen images outputted to the mobile terminal 100 and the video display device 200 are simultaneously updated according to the received input signals.

On the other hand, when the second mode other than the first mode is selected, the controller independently controls one of the first screen and the second screen corresponding to the GUI (S460). That is, the control unit may change the GUI corresponding to the second screen while maintaining the first screen on the basis of the received input signal, and provide the GUI to the display device 200, Only one screen is controlled. Accordingly, different screens are displayed on the display unit 151 and the video display device 200. [

Hereinafter, the first mode will be referred to as a single mode and the second mode will be referred to as a dual mode.

The single mode means that the input means of the mobile terminal 100 and the input device of the display device 200 are integrated and the screen updates of both devices corresponding to the input and the input coincide with each other. The dual mode means that the input means of the mobile terminal 100 is separated from the input means of the display device 200 and the screens of both devices are not matched and updated in accordance with the input. On the other hand, in both the first mode and the second mode, processing of the input signal and screen control are performed only in the mobile terminal 100.

6A and 6B, an operation mode related to the screen control, that is, a first mode and a second mode will be described with specific examples.

Reference numeral 6a is an example of a case where screen control in the mobile terminal 100 operates in a first mode (i.e., a 'single mode').

6A, a first screen 601 output to the display unit 151 of the mobile terminal 100 and a second screen 601 "output to the video display device 200 A screen corresponding to the execution of the same application, for example, the same specific web page screen.

In this case, when the input signal input through the external input device 300, for example, a scroll signal, is transmitted to the mobile terminal 100 through the image display device 200, the mobile terminal 100 processes the input signal The screen 602 outputted to the mobile terminal 100 and the screen 602 'outputted to the video display device 200 are simultaneously updated as shown in (b) of FIG. 6A (for example, Screen is scrolled at the same time).

6A, when the touch gesture is applied to the display unit 151 of the mobile terminal, corresponding screen changes 603 and 603 '' are displayed on the mobile terminal 100 (FIG. 6A) And the image display device 200 simultaneously.

6B is an example of a case where screen control in the mobile terminal 100 operates in a second mode (i.e., a 'dual mode').

In the second mode, the first screen and the second screen may be different screens corresponding to the execution of different applications. However, even in the dual mode, the screen output to the mobile terminal 100 and the screen output to the video display device 200 are the same screen, for example, the same web page screens 601 and 601 " The screen output to the mobile terminal 100 and the screen output to the video display device 200 may be consistent even in the dual mode.

6B, when an input signal, for example, a moving picture playback signal, input through the external input device 300 is transmitted to the mobile terminal 100 through the video display device 200, a moving picture playback screen 602 is output to the video display device 200 as shown in FIG. At this time, the screen and the screen state output to the mobile terminal 100 are maintained. If a corresponding screen change 603 is performed as a predetermined touch gesture is applied to the display unit 151 of the mobile terminal 100 in step (b) of FIG. 6b, the display device 200 outputs The video playback screen was still displayed. That is, the input applied through the image display device 200 and the input applied through the mobile terminal 100 do not affect each other.

The control unit controls the screen in a single mode or a dual mode. When the control unit receives a new input signal related to the screen control, the control unit displays the current operation mode Can be switched. That is, the mode can be switched from the single mode to the dual mode or from the dual mode to the single mode.

In this way, upon switching of the mode related to the screen control, the control unit can output a predetermined alarm. The predetermined alarm may be a pop-up message on the display of the mobile terminal 100 and / or the video display device 200, a predetermined sound, a flicker of the screen, a vibration in the mobile terminal 100, and the like.

As described above, according to the embodiment of the present invention, when the screen output to the mobile terminal is directly output to the wirelessly connected display device, the control of the screen output to both devices is actually performed only in the mobile terminal , The input itself related to the screen control can be independently performed in the mobile terminal and the display device, thereby improving user convenience.

FIG. 7 is an exemplary flowchart illustrating a processing method when an input signal is simultaneously received in a mobile terminal and an image display device in a mobile terminal according to the present invention.

As shown in FIG. 7, the mobile terminal 100 may be wirelessly connected to an external video display device 200 through the wireless communication unit 110 (S710).

At this time, a first screen, for example, a predetermined web page screen, is displayed on the display unit 151 of the mobile terminal 100, and a second screen, for example, a broadcast program screen Can be output.

In step S720, the controller selects a mode of a screen control, that is, a single mode or a dual mode, in response to the mobile terminal 100 and the video display device 200 are wirelessly connected. This selection may be made via user input or based on information or user context related to the status of the device as described above.

Next, the controller detects that the first input signal corresponding to the input applied to the main body of the terminal 100 is received simultaneously with the second input signal received from the display device 200 (S730). Then, the control unit performs processing of the simultaneously received input signals differently according to the current screen control mode.

Specifically, when the current screen control mode is the single mode (i.e., the first mode), the control unit processes the first input signal and the second input signal according to a predetermined priority, And the second screen displayed on the video display device 200 are updated simultaneously (S740).

Here, the predetermined priority may be set by various criteria. Specifically, based on at least one of whether the received input signal is a first input signal or a second input signal, a type of control command corresponding to the received input signal, and status information related to the main body of the terminal 100, The priority of the processing can be determined. For example, the terminal 100 can give priority to the first input signal inputted thereto. Alternatively, when an input signal corresponding to a control command to be processed first, for example, a control command for turning off the screen and a control command for scrolling the screen, is first executed, A control command for scrolling the screen can not be executed. In this case, the control signal for scrolling the screen can be given priority to the input signal. If the battery of the main body of the terminal 100 is insufficient, the terminal 100 can be given priority in terms of power off.

On the other hand, when the current screen control mode is the dual mode (i.e., the second mode), the control unit updates the first screen output to the display unit 151 based on the first input signal, And updates the second screen displayed on the display device 200 based on the input signal. That is, the first input signal and the second input signal are used to update the screen of the corresponding device without affecting each other.

Meanwhile, the mobile terminal 100 disclosed in this specification can operate the dual-mode or single-mode operation of the screen control of the mobile terminal and the display device depending on the situation, and thus can provide a multi-user interface environment . That is, it is possible to switch to a screen control mode suitable for the situation.

Figures 8A, 8B, 9A, 9B, 9C, 10A, 10B, 10C, 10D, 10E, 11, 12A, 12B and 13 are cross- And illustrative conceptual diagrams for explaining an operation mode related to a screen control according to an operation state of the image display apparatus and various user environments.

Hereinafter, Figs. 8A and 8B are views for explaining a method of switching an operation mode related to screen control in a text input state in a single mode.

8A, in a single mode, the control unit displays, in a single area of the web page screen 801 output to the display unit 151 of the mobile terminal 100, It is possible to detect that the text input corresponding to the input signal is applied.

In this case, the control unit switches the single mode to the dual mode to control the screen. As a result, a virtual keyboard screen 802 for inputting text is output only to the display unit 151 as shown in (b) of FIG. 8A. The previously displayed web page screen 801 "is displayed as it is in the video display device 200. This is because it is easy for the mobile terminal 100 to input text through touch input to the display unit 151 .

When the text input is ended through the virtual keyboard screen 802 output to the display unit 151, the control unit changes the dual mode back to the single mode. Accordingly, the virtual keyboard screen 802 disappears from the display unit 151 as shown in (c) of FIG. 8A, and the previously displayed web page screen 801 is output again.

8B, in the single mode, the control unit corresponds to the text input performed in one area of the web page screen 801 "outputted to the video display device 200 as shown in Fig. 8B (a) Lt; / RTI >

In this case, the control unit maintains the single mode so that the text input can also be performed in the main body of the terminal 100. As a result, a virtual keyboard screen 802 is output not only to the video display device 200 but also to the terminal 100 as shown in (b) of FIG. 8B. It is not easy to input text through the external input device 300. Therefore, the user can input an input means such that the user can selectively input text in either the mobile terminal 100 or the image display device 200 When the text input is completed for any device, the control unit outputs the previously displayed web page screens 801 and 801 'to the terminal 100 and the image display apparatus 200, respectively.

9A, 9B and 9C are diagrams for explaining a method of switching an operation mode related to screen control when a specific event, for example, a call signal, is detected in the terminal 100 in the single mode to be.

When an event is generated in at least one application of the main body, the control unit 180 may output a notification icon indicating the occurrence of the event or a corresponding event screen. Herein, the 'event' refers to an event that affects the operation of at least one application installed in the terminal, or a change of an item of a database (or a data file) associated with the at least one application occurs, It means that data is transmitted or transmitted to an external terminal or an external network via at least one application. Here, a case where a call signal is received will be described as an example.

Here, an example in which the camera 221 is provided on the front surface of the image display apparatus 200 will be described. The camera 221 may be any one of a digital camera, a CMOS camera, and a CCD (Charged Coupled Device) camera. In particular, the user may recognize the user's eyes and track the user's gaze along with an infrared sensor .

In this case, the control unit can receive user information existing within a predetermined range based on the display device 200 obtained using the camera. Here, the user information indicates whether a user registered within a predetermined range exists on the basis of the display device 200, or the number of users existing within a predetermined range based on the display device 200.

Next, the control unit may determine whether to switch to the second mode based on the received user information, in response to an event, that is, a call signal, received from the mobile terminal.

Specifically, as shown in FIG. 9A, in the state where the same moving picture playback screen 901, 901 "is outputted to the mobile terminal 100 and the video display device 200 in the single mode, , It is determined based on the user information received from the video display device 200 whether there are a plurality of users viewing the video display device 200 (at least one user other than the user himself / herself) 9A, the single mode is switched to the dual mode. That is, the call signal reception screen 902 corresponding to the call signal is outputted to the terminal 100, The moving picture playback screen 901 "is still outputted to the device 200. [

Also, the controller may change the second mode back to the first mode when the first mode is switched to the second mode based on the received user information, when the detected event ends. That is, when the call signal is terminated, the switched dual mode returns to the single mode, and the moving picture playback screen 901 that was previously output as shown in (c) of FIG. 9 is output again to the display unit 151.

Meanwhile, the controller stops signal processing on the second input signal received from the display device 200 while the terminal 100 detects an event.

For example, as shown in FIGS. 9A and 9B, in the state where the same moving picture playback screen 901, 901 "is outputted to the mobile terminal 100 and the video display device 200, The single mode is switched to the dual mode so that the call signal receiving screen 902 corresponding to the call signal is outputted to the terminal 100 and the moving picture playback The screen is suspended (901 "_A). When the call signal is terminated, the dual mode is switched back to the single mode, and the temporarily stopped moving image reproduction screen is output to the display unit 151 and the image display device 200 again (903, 903 "). The control unit maintains a state in which the second input signal received from the video display device 200 input in the dual mode is not processed until the end of the call signal, have.

9C, when the video call is received in the mobile terminal 100 and the video call is preset to be performed also in the video display device 200, when the video call signal is received, The video call screen is simultaneously output to the mobile terminal 100 and the video display device 200. [ That is, the single mode in Fig. 9C (a) is maintained. When the video call ends, the moving picture playback screen outputted in (a) of FIG. 9C is output again (903, 903 ").

10A, 10B, 10C, and 10D are embodiments for explaining a method of switching an operation mode related to screen control according to user input or in a specific scene.

In response to the detection of a preset gesture input in the main body of the terminal 100 in a state in which the first screen and the second screen are being output to the mobile terminal 100 and the video display device 200, It is possible to switch from the first mode to the second mode or to switch from the second mode to the first mode.

10A shows a case where a predetermined user gesture is input to the terminal 100 as shown in FIG. 10A when the terminal 100 and the video display device 200 operate in the single mode, Mode is switched to dual mode. Accordingly, only the moving picture playback screen 1001 output from the display unit 151 of the terminal in (a) of FIG. 10A is switched to the predetermined web page screen 1002 as shown in (c) of FIG. 10A.

Here, the gesture of shaking the main body of the terminal while pressing a specific key (e.g., a home key) of the terminal has been described as an example of the predetermined user gesture. However, the gesture is not limited thereto. May be performed by at least one combination.

On the other hand, FIG. 10B is an example of a case where a predetermined user gesture is applied to the terminal 100 to switch to the single mode when the terminal 100 and the video display device 200 operate in the dual mode. In this case, a UI (User Interface) 1002B, 1002B "associated with the screen control may be displayed in one area of the screen output to the terminal 100 and the video display device 200 as shown in FIG. 10 (c) .

10C illustrates an example in which a preset user gesture is performed through an external input device 300 connected to the image display device 200 when the terminal 100 and the image display device 200 operate in a dual mode 10D illustrates a case where a predetermined user gesture is performed through a mode switching UI 1003 output from the touch screen of the video display device 200 when the terminal 100 and the video display device 200 operate in the dual mode . The mode switching may be performed, for example, when the viewer of the video display apparatus 200 wants to share a specific scene with the terminal 100 user.

Meanwhile, when the time information for requesting the input of the user information, for example, the user login input area, is displayed on the second screen displayed on the display device 200 while the dual mode is being executed, To the single mode for a predetermined time. Accordingly, it is possible to induce the user of the terminal to perform the input of the user information.

12 is a flowchart illustrating a method of switching an operation mode related to screen control in a state where different screens are displayed on the mobile terminal 100 and the video display device 200 Fig.

When the wireless connection between the main body of the terminal 100 and the video display device 200 is released in the dual mode, the control unit switches the dual mode to the single mode so that the second screen displayed on the video display device is displayed on the display unit can do. 11 (b), the web page screen 1101 output to the video display device 100 in (a) is output to the display unit 151 (1101 "). In this case , A notification icon indicating that the wireless connection is released, and a 'disconnected' 1103 may be output to the display unit 151 as shown in FIG. 11 (b).

On the other hand, when the wireless connection between the main body of the single mode terminal 100 and the video display device 200 is released, only the notification icon corresponding to the wireless connection can be output without switching the screen control mode.

Hereinafter, FIGS. 12A, 12B, and 13 are views illustrating a method of switching an operation mode related to screen control when the battery of the terminal is insufficient.

While the mobile terminal 100 and the video display device 200 are being operated in the dual mode, the controller may detect that the power of the battery included in the main body of the terminal 100 is reduced to be less than the reference value.

That is, when the power of the battery of the terminal is insufficient, the controller controls the display device 200 to output a message for switching the dual mode to the single mode. That is, as shown in FIG. 12A, an image 1210 indicating that the battery is low is output to the display unit 151 of the terminal, and the image 1210 of the screen 1202 output to the video display device 200 Area 1220, there is a low battery. Do you want to switch to single mode? "Message pops up. Then, when mode switching is performed or a predetermined period of time elapses, the single mode is automatically executed as shown in (b) of FIG. 12A. 12A, the display unit 151 is deactivated and a screen that was originally output to the terminal is output to the image display apparatus 200 (1201 " ).

If it is determined that the power of the battery included in the main body of the terminal 100 is equal to or lower than the reference value while the single mode is being executed, if the input for attempting to switch to the dual mode is sensed, d) A notification icon indicating that you can not switch to dual mode, 'The battery is low. Quot ;, " unable to switch to dual mode ", is output to the display device 200.

Meanwhile, when the display unit 151 of the terminal is activated again according to the battery charging or the like, the control unit controls the screen in the mode that was executed at the point in time when the display unit was inactivated. That is, as shown in FIG. 12B, the screen is controlled in a single mode, which is an operation mode prior to mode switching. Accordingly, a screen 1201 identical to the web page screen 1201 " output to the video display device 200 is output to the display unit 151. [

13, when the battery power of the terminal 100 is lower than the reference value, a message for inducing a connection with another device is transmitted to the display device 200 through the mobile terminal 100 ). As a result, as shown in FIG. 13B, the screen 1303 is switched to display a plurality of external devices connectable in the vicinity. When the user selects a thumbnail of the external device to be connected on the displayed screen 1303, the connection to the corresponding external device can be performed. At this time, the operation mode related to the screen control is determined according to the setting of the external device to which the connection is made.

As described above, the mobile terminal and the control method thereof according to the embodiment of the present invention allow a mobile terminal including various functions and a simple display device to be wirelessly connected to each other, The non-smart display device can display various contents by utilizing the resources of the mobile terminal.

In addition, when a screen output to the mobile terminal is output to a wirelessly connected display device, the screen output to both devices is actually controlled only by the mobile terminal, but the input itself related to the screen control is controlled by the mobile terminal and the display device It can be performed independently, thereby improving user convenience.

In addition, the application range of the device to be subjected to the screen update corresponding to the received input may be differently applied based on the operation state of the wirelessly-connected mobile terminal and the display device and various user environments. That is, the screen control of the mobile terminal and the display device can be operated in the dual mode or the single mode according to the circumstances, thereby providing a multi-user interface environment to the user.

Furthermore, the present invention can be embodied as computer-readable code on a medium on 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 the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
