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 existing in the vicinity without mechanical contact using the force of an electromagnetic field 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 type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive type proximity sensor, a magnetic type proximity sensor, and an infrared proximity sensor. When the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of an object having conductivity by a change in an electric field according to the proximity of the 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 description, the act of approaching an object on the touch screen without contacting it so that the object is recognized that it is located on the touch screen is called “proximity touch”, and the touch The act of actually touching an object on the screen is called "contact touch". The position where the object is touched in proximity on the touch screen means a position where the object is perpendicular to the touch screen when the object is touched in proximity. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.) have. Meanwhile, the controller 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 printed on the touch screen. Furthermore, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) according to whether a touch to the same point on the touch screen is a proximity touch or a contact touch. .

The touch sensor receives a touch (or touch input) applied to the touch screen (or the display unit 151) using at least one of various touch methods such as a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method. detect

As an example, the touch sensor may be configured to convert a change in pressure applied to a specific part of the touch screen or a change in capacitance occurring in a specific part of the touch screen into an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, an electrostatic capacitance at the time of touch, etc. in which a touch object applying a touch on the touch screen is touched on the touch sensor. Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen, a stylus pen, or a pointer.

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

Meanwhile, the controller 180 may perform different controls or may perform the same control according to the type of the 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 the touch object may be determined according to the current operating state of the mobile terminal 100 or a running application program.

The ultrasonic sensor may recognize position information of a sensing target by using ultrasonic waves. Meanwhile, the controller 180 may calculate the position of the wave source through information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source may be calculated using the property that light is much faster than ultrasonic waves, that is, the time at which light arrives at the optical sensor is much faster than the time at which ultrasonic waves reach the ultrasonic sensor. More specifically, the position of the wave source may be calculated using a time difference from the time that the ultrasonic wave arrives using light as a reference signal.

On the other hand, the camera 121 as seen in the configuration of the input unit 120 includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or 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 target for a 3D stereoscopic image. The photo sensor may be stacked on the display device, and the photo sensor is configured to scan the motion of the sensing target close to the touch screen. More specifically, the photo sensor mounts photo diodes and transistors (TRs) in rows/columns and scans the contents placed on the photo sensors using electrical signals that change according to the amount of light applied to the photo diodes. That is, the photo sensor calculates the coordinates of the sensing target according to the amount of change in light, and through this, location information of the sensing target 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 UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information. .

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

A three-dimensional display method such as a stereoscopic method (glasses method), an auto stereoscopic method (glassesless method), or a projection method (holographic method) may be applied to the stereoscopic display unit.

The sound output unit 152 may output audio data received from the wireless communication unit 110 or stored in the memory 170 in a call signal reception, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, and the like.

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

The haptic module 153 generates various tactile effects that the user can feel. A representative example of the tactile effect generated by the haptic module 153 may be vibration.

It is apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

3 is a flowchart representatively showing the control method of the present invention, and FIGS. 4, 5A, 5B and 5C are conceptual diagrams for explaining the control method described in FIG. 3 .

First, referring to FIG. 3 , in the present invention, a step of interconnecting the image output apparatus 200 to perform wireless communication with at least one mobile terminal 100 is performed (S310). Specifically, when a wireless connection request signal for performing wireless communication is received from the mobile terminal 100, the controller 280 of the image output device 200 communicates with the mobile terminal 100 that has transmitted the request signal. It can be connected to make this possible.

In this case, the connection may be performed based on a user's request (eg, an acceptance (approval) command, a user control command) through the image output device 200 . In addition, when the mobile terminal 100 is a previously connected device or a previously registered mobile terminal, when the request signal is received, the connection may be performed without a separate user request.

The image output device 200 may be connected to at least one mobile terminal 100 through the interface unit 260 (or a wireless communication unit) to enable wireless communication. At this time, the mobile terminal 100 transmits the wireless connection request signal to the image output device 200 through the wireless communication unit 110 , and wirelessly communicates with the image output device 200 through the wireless communication unit 110 . can be connected to

Thereafter, the image output apparatus 200 of the present invention outputs a graphic object related to a mobile terminal connected to enable wireless communication and an image related to an application (S320).

Specifically, when the controller 280 of the image output device 200 is connected to at least one mobile terminal 100 to perform wireless communication, the display unit displays a graphic object related to the connected at least one mobile terminal 100 . (251) can be output.

The graphic objects 410a and 410b may include information related to at least one mobile terminal 100a and 100b connected to perform wireless communication, for example, as shown in FIG. 4 . The information includes a user name (or device name, product name, etc.) set in the connected mobile terminal, a serial number (unique number) of the connected mobile terminal, and a representative image (eg, profile image, etc.) set in the connected mobile terminal. ), a phone number, an email address, and the like. In addition, as long as the information is unique information capable of identifying a mobile terminal, any form may be employed.

The graphic objects 410a and 410b may be displayed on the display unit 251 of the image output apparatus 200 in various ways. For example, the controller 280 may display the graphic objects 410a and 410b on the display unit 251 based on the at least one mobile terminal 100a, 100b being connected through the wireless communication unit. . The graphic objects 410a and 410b may disappear from the display unit 251 after a preset time elapses after being output to the display unit 251 , or may be continuously output.

In the present invention, by outputting the graphic objects 410a and 410b to the display unit 251 of the image output apparatus 200, the number of mobile terminals connected to the image output apparatus 200 to perform wireless communication and the connected mobile terminals It can serve to inform the user of related information.

Meanwhile, the controller 280 may output an image 420 related to an application to the display unit 251 . The image 420 related to the application may mean a menu (or a user interface, icon, graphic object, graphic image, etc.) capable of executing an application installed in the image output device 200 . The controller 280 may display a plurality of images related to a plurality of applications.

The menu may be understood as a concept including a plurality of images related to the plurality of applications. Also, the image 420 related to the application may have the same concept as the menu or a concept included in the menu.

When any one of the plurality of images is selected, the controller 280 may execute an application associated with (or corresponding to) the selected image, and output an execution screen of the executed application to the display unit 251 . .

The image 420 related to the application and the graphic objects 410a and 410b related to a mobile terminal connected to enable wireless communication may be output based on a user request (or a user control command). Here, the user request is, a function button (eg, a menu button) provided in the external input device 300 is selected (or pushed, touched) or a touch of the mobile terminal 100 connected to enable wireless communication It may include selecting a function icon (eg, an icon associated with a menu output function) output on the screen 151 . That is, the controller 280, based on a user request, among the image 420 (or menu) related to the application and the graphic objects 410a and 410b related to the mobile terminals 100a and 100b connected to enable wireless communication. At least one may be output to the display unit 251 .

Then, in the present invention, when the drag input starting from the graphic object related to the connected mobile terminal is released from the image related to the application, the application displayed on the mobile terminal corresponding to the graphic object among the execution screens of the application linked to the image A step of outputting the execution screen of the to the display unit 251 proceeds (S330).

Specifically, when the image 420 (or menu) related to the application and the graphic objects 410a and 410b related to the mobile terminal connected to perform wireless communication are output to the display unit 251 ( Alternatively, if there is a user's request), a cursor may be output to the display unit 251 .

The cursor may be controlled (or moved) based on at least one of the external input device 300 and the mobile terminal 100 connected to enable wireless communication. For example, the control unit 280 of the image output device 200 may be configured based on a signal generated when a manipulation key provided in the external input device 300 is pushed or a user's movement of the external input device 300 . When the generated signal is received, the cursor may be controlled based on the signal. The signal may be generated by the external input device 300 and then transmitted to the image output device 200 .

As another example, the controller 280 may include a signal generated when a touch is applied to an operation interface output to the touch screen 251 of the mobile terminal 100 connected to perform wireless communication or a touch screen of the mobile terminal 100 . When a signal generated by a touch (eg, drag touch, etc.) applied to 251 and a signal generated based on the movement of the mobile terminal 100 are received, the cursor can be controlled based on the signal. can The signal may be generated by the controller 180 of the mobile terminal 100 and then transmitted to the image output device 200 through wireless communication.

The drag input starting from the graphic object may mean, for example, an input in which the cursor is moved while the graphic object is selected. For example, when a cursor is moved to a state in which the graphic object is selected (clicked) through manipulation of an external input device (or mobile terminal), the controller 280 performs the above operation by dragging the graphic object It can be decided (judgmented) by input.

As shown in (a) of FIG. 5A , the controller 280 is a drag starting from a graphic object 410a related to a mobile terminal (eg, the first mobile terminal 100a) connected to enable wireless communication. When an input is released (or canceled) in any one 420a of the image 420 related to the application, the application related to the image 420a corresponding to the one may be executed.

For example, when the image 420a corresponding to any one is an image 420a associated with a function of executing a specific application, the controller 280 executes the specific application based on the drag input, An execution screen of the executed specific application may be output to the display unit 251 .

On the other hand, the control unit 280, the display unit to output the execution screen of the application displayed on the mobile terminal 100a corresponding to the graphic object 410a from which the drag input is started among the execution screens of the application linked to the image 420a (251) can be controlled.

Specifically, an application linked to the image 420a may be installed in the mobile terminal 100a. In addition, in the mobile terminal 100a, as the application linked to the image 420a is running, an execution screen of the application may be output to the touch screen 151 .

The control unit 280 of the image output device 200, based on a drag input starting from the graphic object 410a, displays the execution screen of the application displayed on the mobile terminal 100a corresponding to the graphic object 410a. It can output directly to the display unit 251 of the image output device 200 .

For example, as shown in (a) of FIG. 5A , when a drag input starting from the graphic object 410a related to the first mobile terminal is released from the image 420a related to a specific application, the controller 280 is , as shown in (b) of FIG. 5A , the execution screen 510a of the specific application being output from the first mobile terminal may be output to the display unit 251 of the image output apparatus 200 .

For example, when the drag input is released, the controller 280 transmits a signal requesting transmission of the execution screen of the specific application to the first mobile terminal to the first mobile terminal, and sends the specific application from the first mobile terminal to the first mobile terminal. You can receive the execution screen of the application. In this case, the controller 280 may receive not only the execution screen of the specific application, but also content information, URL information, link information, and the like. Such an operation may be understood as, for example, a mirroring function.

Thereafter, the controller 280 may output the execution screen of the specific application received from the first mobile terminal to the display unit 251 .

As another example, as shown in (a) of Figure 5b, when the drag input starting from the graphic object 410b related to the second mobile terminal is released from the image 420a related to a specific application, the control unit 280, As shown in (b) of FIG. 5B , the display unit 251 of the image output device 200 displays the execution screen 510b of the specific application being output from the second mobile terminal among the execution screens of the specific application. can be printed on

That is, when a plurality of mobile terminals 100a and 100b are connected to the display unit 251 of the image output apparatus 200 through a wireless communication unit, a plurality of graphic objects 410a and 410b related to the connected plurality of mobile terminals are provided. can be output.

Thereafter, as shown in FIG. 5A , when the drag input is started on a first graphic object 410a among the plurality of graphic objects, the control unit 280 includes a first graphic object corresponding to the first graphic object 410a. The first execution screen 510a of the application displayed on the mobile terminal 100a may be output to the display unit 251 .

Also, as shown in FIG. 5B , when the drag input is started in a second graphic object 420a different from the first graphic object 410a, the control unit 280 is displayed on the second graphic object 410b. The second execution screen 510b of the application displayed on the corresponding second mobile terminal 100b may be output to the display unit 251 .

If, in a mobile terminal connected to enable wireless communication, the execution screen of the application for which the drag input is released is not output (that is, when the application is not running), the display unit 251 displays the image A preset execution screen among execution screens of applications linked to may be output.

Here, the preset execution screen is at least one of an execution screen of the application most recently output from the mobile terminal corresponding to a graphic object from which a drag input is started, and an execution screen of the application designated to be output to an image output device in the mobile terminal. may contain one.

That is, the controller 280 may transmit a signal requesting transmission of an execution screen of an application linked to the image in which the drag input is released to the mobile terminal corresponding to the graphic object from which the drag input has been started. When the execution screen of the application linked to the image is being output to the touch screen 151, the controller 180 of the mobile terminal outputs information related to the execution screen (or the execution screen) to the image output device 200 . can be sent to On the other hand, if the execution screen of the application linked to the image is not being output on the touch screen 151, the controller 180 of the mobile terminal may Information (or execution screen) related to the execution screen of the corresponding application designated by the user may be transmitted to the image output device 200 . In this case, the most recently output execution screen or an execution screen of a corresponding application designated by the user may be output to the display unit 251 of the image output apparatus 200 .

Meanwhile, as illustrated in (a) of FIG. 5C , a plurality of images 420a and 420b related to a plurality of applications may be displayed on the display unit 251 of the image output apparatus 200 .

The controller 280, as described above, when the drag input starting from the graphic object 410b related to the mobile terminal connected to enable wireless communication is released from the image 420a related to the first application, displayed on the mobile terminal An execution screen 510b of the first application may be output to the display unit 251 .

In this state, that is, in a state in which the execution screen of the first application displayed on the mobile terminal is output by the drag input, a new drag input starting from the graphic object 410b is an image 420a related to the first application. When it is released from an image 420b different from , the controller 280 may divide the display area of the display unit 251 . For example, the controller 280 may divide the display area of the display unit 251 into a first display area 520a and a second display area 520b based on the new drag input. Hereinafter, division into two display areas will be described as an example for convenience of description, but the present invention is not limited thereto.

In addition, as shown in (b) of FIG. 5C , the controller 280, based on the new drag input, is configured to display an execution screen ( 510b) may be displayed. In addition, based on the new drag input, the controller 280 may be configured to display an execution screen ( 530b) can be output.

In this case, the execution screen 530b of the second application displayed on the second display area 520b is the execution screen of the second application being output from the mobile terminal corresponding to the graphic object 410b or the second It may be the most recently output execution screen among the execution screens of the application. In addition, the execution screen 530b of the second application displayed on the second display area 520b is designated to be output from the image output device 200 by the user in the mobile terminal corresponding to the graphic object 410b. It may be an execution screen of the second application.

Although not shown, as shown in (a) of FIG. 5C , the execution screen of the first application being output to the second mobile terminal corresponding to the second graphic object 410b is displayed on the display unit of the image output device 200 . In the state being output to 251, a new drag touch starting from a first graphic object 410a different from the second graphic object may be released from the image related to the first application (or the image related to the second application) have. Likewise in this case, the control unit 280 divides the display area of the display unit 251, and the first application being output to the first mobile terminal corresponding to the first graphic object 410a in the second display area. may output an execution screen (or an execution screen of the second application) to the display unit 251 of the image output apparatus 200 .

Through this configuration, in the present invention, a user who can output screen information (or an application execution screen) output to the mobile terminal connected to the image output device to enable wireless communication in an optimized method on the display unit of the image output device interface can be provided.

Hereinafter, various control methods using graphic objects related to a mobile terminal connected to enable wireless communication in the present invention and images related to applications will be described.

The controller 280 executes a preset application when a drag input starting from any one graphic object among the plurality of graphic objects is released from the graphic object other than the one other than the image related to the application. A possible selection window may be output to the display unit 251 .

Thereafter, when any one of the graphic images included in the selection window is selected, the controller 280 may divide the display area of the display unit 251 . In addition, the control unit 280 is configured to control the application displayed on the first mobile terminal corresponding to the one graphic object among the execution screens of the application linked to the selected graphic image in the first display area of the display unit 251 . You can print the execution screen.]

In addition, the control unit 280 is configured to control the application displayed on the second mobile terminal corresponding to the other graphic object among the execution screens of the application linked to the selected graphic image in the second display area of the display unit 251 .

For example, as shown in (a) of FIG. 6 , a drag input starting from a first graphic object 610a among a plurality of graphic objects 610a and 610b displayed on the display unit 251 is a second graphic object. When released in step 620a, the controller 280 may output a selection window 600 capable of executing a preset application, as shown in FIG. 6B .
