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.

In the watch-type mobile terminal 300 according to the present invention, when the main body 301 and the display unit 351 are separated from each other, the camera unit 321 connected to the display unit 351 may be separated . In this case, the camera 321 may be controlled by a control unit separately provided to the control unit 180 or the display unit 351 of the main body, like the display unit 351.

In addition, the watch-type mobile terminal 300 according to the present invention may include not only a display unit detachable from the main body but also a display unit not detachable from the main body 301. [

At this time, the controller 180 may separately control the display unit detachable from the main body, and the display unit not detachable from the main body. In addition, screen information related to each other may be displayed on each display unit, or irrelevant screen information may be displayed.

Hereinafter, embodiments related to a control method that can be implemented in a watch-type mobile terminal configured as described above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

4 is a flowchart illustrating a control method of a watch-type terminal according to an embodiment of the present invention, and FIGS. 5A and 5B are conceptual diagrams illustrating a control method of FIG.

First, a watch-type mobile terminal according to an embodiment of the present invention can detect whether the main body and the display unit are separated (S410).

The watch-type mobile terminal 300 may include a main body 301, a display portion 351, and a band 302.

The main body 301 may be formed such that the display portion 351 can be detached or coupled. More specifically, the main body 301 may further include an engaging portion formed to be engageable with and detachable from the display portion 351.

The main body 301 may include the control unit 180, the wireless communication unit 110, and the memory unit 170 described with reference to FIG. 1A.

The control unit 180 may control the display unit 351 based on the combination and separation of the display unit 351.

More specifically, when the display unit 351 is coupled to the main body 301, the controller 180 may be directly connected to the display unit 351 to control the display unit 351. When the display unit 351 is separated from the main body 301, the control unit 180 can control the display unit 351 through communication. At this time, the watch-type mobile terminal may be provided with a communication unit connected to the separate display unit 351 and capable of performing communication with the main body 301.

The control unit 180 may transmit a control command to the display unit 351 when the display unit 351 is separated from the main body. For example, when the display unit 351 is separated from the main body 301, the control unit 180 may transmit a control command for controlling the transparency of the display unit 351.

The display unit 351 detachable from the main body 301 includes a communication unit (not shown) for performing communication with the main body 301 when the main body 301 is separated from the main body 301 and a camera 321 ). At this time, the communication unit and the camera 321 may be separated from the main body 301 together with the display unit 351.

In addition, the display unit 351 detachable from the main body 301 may be formed to adjust the transparency. The transparency of the display unit 351 may be defined as the degree of transmission of light incident on the display unit 351. For example, the transparency of the display unit 351 may be defined as a ratio of the amount of light transmitted through the display unit to the amount of transmitted light. In addition, the transparency of the display unit 351 may be defined in various formats indicating the degree of transmission of light in addition to the above-described method.

The control unit 180 may control the transparency of the display unit 351. At this time, the controller 180 may control the transparency of the display unit 351 so that an object located behind the display unit 351 is displayed to the user. For example, when the display portion 351 has high transparency, the display portion 351 can transmit most of incident light. At this time, the user can see an object positioned behind the display unit 351. [

In addition, when the transparency of the display unit 351 is low, the display unit 351 may not transmit most of incident light. In this case, the user can see an object positioned behind the display unit 351. [

In addition, the display unit 351 can display the screen information even when the display unit 351 is separated from the main body 301. For example, the display unit 351 may display screen information related to a function performed by the control unit 180 of the main body 301 in a state separated from the main body 301. In this case, the controller 180 may transmit information related to the screen information to be displayed on the display unit 351 to the display unit 351 through communication.

Meanwhile, the watch-type mobile terminal may be in any one of a locked state in which a user's control command is received and a released state in which a user's control command can be received.

When the watch-type mobile terminal is in a locked state, the display unit 351 may be inactivated or partially activated. At this time, the display unit 351 is deactivated because the illumination is turned off on the display unit 351 and the screen information is not displayed. On the contrary, the activation of the display unit 351 may be a state in which the illumination is turned on on the display unit 351 to display the screen information.

Further, the display unit 351 may be partially activated when the display unit 351 is partially illuminated, and only a part of the screen information is displayed. For example, as shown in (a) of FIG. 12A, when the watch-type mobile terminal is in the locked state, simple information indicating time can be displayed on the display unit 351. In this case, the display unit 351 may not activate the entire display unit 351, but may activate only a part of the display unit 351 to provide time information.

Accordingly, the display unit 351 is partially activated, so that the present invention can reduce the consumption of the battery and provide the user with the minimum amount of information.

Meanwhile, when the watch-type mobile terminal is in the locked state, the controller 180 can switch the locked state to the released state when the separation between the main body 301 and the display unit 351 is detected.

For example, as shown in FIG. 12A, when the watch-type mobile terminal is in a locked state, the controller 180 detects that the display unit 351 is separated from the main body 301 .

12A, when the display unit 351 is disconnected, the control unit 180 switches the lock state to the released state, and the display unit 351 displays a home screen The page can be displayed. Here, the home screen page may be screen information displayed in a standby state, and may be screen information showing an icon representing an application, a widget, and the like.

The control unit 180 switches the locked state to the released state and activates the camera 321 connected to the display unit 351 when the separation of the main body 301 and the display unit 351 is detected . For example, as shown in (c) of FIG. 12, the controller 180 activates the camera 321 and displays the image received from the camera 321 on the display unit 351 can do.

The control unit 180 may output the screen information for switching the locked state to the released state on the display unit 351 when the separation of the main body 301 and the display unit 351 is detected .

More specifically, when the separation of the display unit 351 is sensed, the control unit 180 may display a lock screen for releasing the locked state on the display unit 351. FIG.

Here, the commercial lock screen may indicate various canceling methods preset in the watch-type mobile terminal such as a screen for inputting pattern information for canceling the locked state, a screen for inputting a password, a screen for performing face recognition, Lt; / RTI > For example, as shown in (d) of FIG. 12, the control unit 180 may output a screen for receiving pattern information for releasing the locked state on the display unit 351.

That is, according to the present invention, when the watch-type mobile terminal detects the detachment of the display unit 351 in the locked state, it can perform various controls for releasing the locked state.

More specifically, the control unit 180 can receive the identification information of the external object via the camera 321 in a state in which an external object is displayed on the display unit 351. [ At this time, the control unit 180 can receive information related to the external object from the external server using the identification information. Then, the controller 180 may display the received information on the area of the display unit 351 corresponding to the position of the external object.

Accordingly, the user can easily receive the external environment information desired by the user by moving only the display unit 351.

The present invention enables detachment of the display unit and the main body, thereby alleviating the limitation of movement of the watch-type mobile terminal due to wearing on the wrist. Further, the present invention secures the degree of freedom of movement of the camera provided in the watch-type mobile terminal, thereby making it possible to secure the view of the camera more easily.

The control method of the watch-type mobile terminal in the case where the display unit and the main body are separated has been described above.

Hereinafter, a method of controlling the separated display unit when the display unit and the main body are separated will be described in more detail. 6A and 6B are conceptual diagrams illustrating a method of capturing an image when the display unit and the main body are separated.

When the main body 301 and the display unit 351 are separated from each other, the control unit 180 included in the main body 301 controls the display unit 351 through communication with the separated display unit 351 . For example, when the display unit 351 is disconnected, the control unit 180 may transmit a photographing command through communication to perform photographing using the camera 321 connected to the display unit 351 .

That is, as shown in (a) of FIG. 6A, the control unit 180 can transmit a photographing command to the display unit 351 through communication. In this case, the camera 321 connected to the display unit 351 can photograph an image according to the photographing command.

That is, even when the display unit 351 is disconnected, the user can control the display unit 351 using the main body 301 worn on the wrist.

Meanwhile, the display unit 351 may be controlled based on a control command received from the main body, but may be controlled by a control unit connected to the display unit 351 itself. That is, in this case, the separated display unit 351 may be provided with a control unit that can control only the display unit 351.

In this case, the control unit separately provided on the display unit 351 can perform photographing using the camera 321 when a touch is applied to the display unit 351. That is, the present invention can perform image capturing through a control unit provided in the main body 301 or image capturing through a control unit provided separately on the display unit 351.

In addition, when the display unit 351 captures an image, the captured image may be transmitted to the main body 301 through communication. For example, as shown in (b) of FIG. 6, when the image is taken on the display unit 351, the photographed image may be transmitted to the main body 301. In this case, the control unit 180 may store the image in the memory unit 170. [

Meanwhile, the control command can be generated by various methods. Here, the control command may be generated by various methods such as touch input, voice input, and gesture input to the main body.

For example, the control unit 180 may generate a control command based on the movement of the main body 301. [ More specifically, the controller 180 may detect a movement of a wrist worn by a watch-type mobile terminal and generate a control command.

At this time, the controller 180 may generate different control commands for performing different functions based on the movement direction of the wrist. For example, the controller 180 may generate a first control command when it is sensed that the wrist is moving in a first direction, and may generate a second control command when it is sensed that the wrist is moving in a second direction .

For example, as shown in (a) of FIG. 6, when the wrist is detected to rotate in the first direction, the controller 180 controls the camera 321, which is connected to the display unit 351, Lt; RTI ID = 0.0 > a < / RTI > The control unit 180 may transmit a control command to the display unit 351, which is separated from the main body 301, through the communication.

Referring to FIG. 6 (a), a moving image currently being photographed may be displayed on the display unit 351. FIG. In addition, a graphic object 600 indicating that the current moving image is being captured may be displayed on the display unit 351 together. Through this, the user can know that the current movie is being shot.

6 (b), when the control unit 180 detects that the wrist is rotated in the second direction, the controller 180 controls the display unit 351 to move the still image It is possible to generate a control command for performing the photographing operation. As described above, the control unit 180 can transmit a control command for performing shooting of the still image through communication.

6B, the image received from the camera 321 is output on the display unit 351, and a graphic object 610 indicating that the current still image is being captured is displayed on the display unit 351. In this case, May be displayed.

In the above description, the case where the camera is activated has been described. However, the present invention is not limited to this, and after the display unit 351 is separated, it can provide various functions that can be executed in the mobile terminal by the control command received from the main body.

That is, the present invention can display the functions currently being executed in the main body 301 on the separate display portion 351. [ In this case, the control unit 180 may transmit various control commands related to the function through communication. Here, the currently executing function may be a function executable in a watch-type mobile terminal. For example, it may be a function to execute an application installed in a watch-type mobile terminal.

A method of transmitting a control command when the main body 301 and the display unit 351 are separated has been described above. Accordingly, the present invention can control the display unit separated only by the operation of the main body, without applying any other operation to the display unit.

Further, the present invention can prevent movement of the camera field of view by performing image capturing without operating a display unit to which a camera is connected. Thus, the present invention can obtain a clearer image without moving the camera.

Hereinafter, a method of performing different functions according to the manner in which the display unit is separated from the main body will be described. 7 is a conceptual diagram illustrating a display unit provided in a watch-type mobile terminal rotating. 8 is a conceptual diagram illustrating that different functions are performed according to the degree of rotation of the display unit included in the watch-type mobile terminal.

The watch-type mobile terminal according to an embodiment of the present invention may be configured to be rotatable in a state where the display unit 351 is coupled to the main body. At this time, the display unit 351 may be circular to be rotatable.

Also, the controller 180 may detect the degree of rotation of the display unit 351. More specifically, the control unit 180 may sense the rotation angle of the display unit 351 based on a case where the display unit 351 is at the reference position with respect to the main body 301. [ Here, the reference position may be a preset position at the factory of the watch-type mobile terminal.

In addition, when the display unit 351 is rotated, the controller 180 may display a graphic object indicating the degree of rotation of the display unit 351 in one area. 7 (a), in a state where the display unit 351 is at a reference position with respect to the main body 301, the control unit 180 controls the display unit 351 Rotation can be detected.

At this time, the control unit 180 may display the graphic object 700 indicating the degree of the rotation on the edge region of the display unit 351.

When the display unit 351 is rotated, the controller 180 may sense the rotation of the display unit 351. For example, as shown in FIG. 7 (b), the controller 180 may sense an angle? ₁ in which the display unit 351 is rotated clockwise.

At this time, the controller 180 may perform a function associated with the rotated angle based on the angle at which the display unit 351 is rotated. In addition, the controller 180 may perform different functions based on the rotation angle of the display unit 351.

8A, when the display unit 351 is rotated, the controller 180 displays graphic objects 800a and 800b indicating the functions associated with the respective rotation angles, To the area of the display section 351 corresponding to the angle.

For example, when the rotation of the display unit 351 is detected, the controller 180 displays a graphic object 800a indicating a camera function and a graphic object 800b indicating a timer function on a region corresponding to each rotation angle, Can be output.

At this time, when the display unit 351 is separated from the main body 301 in a state where the display unit 351 is rotated at a rotation angle corresponding to a predetermined rotation angle, the controller 180 can perform a function associated with the rotation angle have.

For example, as shown in FIGS. 8A and 8B, when the display unit 351 is separated from the main body 301 while the display unit 351 is rotated at the first angle, It is possible to execute the camera function and display an execution screen indicating the execution of the camera function on the display unit 351. [

As another example, when the display unit 351 is separated from the main body 301 while the display unit 351 is rotated at the second angle, as shown in FIGS. 8A and 8B, A timer function may be executed and an execution screen related to the execution of the timer function may be displayed on the display unit 351. [

In the above description, the function is executed when the display unit 351 is rotated and then separated. However, the present invention can be applied to a case where the rotational angle of the fraud indicator 351 coincides with a predetermined angle, It may perform a function associated with the rotation angle.

Accordingly, when the display unit and the main body are separated from each other, the present invention can provide different functions depending on the rotation angle at the time of separation of the display unit and the main body.

Hereinafter, a method of performing different functions according to the coupling angle when the separated display unit and the main body are coupled will be described. FIGS. 9A, 9B, and 9C are conceptual diagrams showing that different functions are performed depending on the angle when the separate display units are combined.

The control unit 180 can sense the rotation angle when the display unit 351 is separated from the main body 301. [ In addition, the controller 180 may sense a rotation angle when the display unit 351 and the main body 301 are coupled.

At this time, the control unit 180 may perform different functions according to the rotation angle when the display unit 351 is coupled to the main body. Here, the controller 180 may sense an angle of the clockwise rotation of the display unit 351 and the main body 301 with reference to the reference position.

For example, as shown in FIGS. 9A and 9B, the controller 180 may detect that the display unit 351 is coupled with the main body 301 at a first angle . At this time, the controller 180 may synchronize files stored in the memory unit 170 associated with the first angle. Here, the function of synchronizing files may mean the function of storing temporarily generated files not stored in the memory unit 170 in the memory unit 170. In addition, the function of synchronizing files may mean a function of detecting files not stored in another one from two devices separated from each other and transmitting the files to any one of them.

The control unit 180 synchronizes the files temporarily stored on the display unit 351 with the main body 301 when it is detected that the display unit 351 is coupled to the main body 301 at the first angle Can be performed. At this time, on the display unit 351, screen information indicating that files are being synchronized may be displayed. For example, as shown in (c) and (d) of FIG. 9A, the control unit 180 may synchronize files and display screen information indicating that synchronization is being performed on the display unit 351 have.

The display unit 351 may have a circular shape and may be rotatable with respect to the main body 301. However, the display unit 351 may have a rectangular shape and may not be rotatable with respect to the main body 301. [ For example, as shown in FIG. 9 (b), the display unit 351 may be formed in a rectangular shape and may not be rotatable with the main body 301.

In this case, the controller 180 may detect an angle at which the display unit 351 and the main body 301 are coupled. For example, when the display unit 351 is rectangular, the controller 180 detects that the display unit 351 is coupled at an angle of 0 degree, 90 degrees, 180 degrees, or 270 degrees based on a predetermined reference position can do.

At this time, the controller 180 may perform different functions based on the combined angles. For example, as shown in FIGS. 9 (a) and 9 (b), the controller 180 may detect that the display unit 351 and the main body 301 are at a first angle, have. At this time, as shown in (c) of FIG. 9, the controller 180 may perform a function of synchronizing files having functions associated with the first angle.

As another example, as shown in FIGS. 9 (a) and 9 (b), the controller 180 may detect that the display unit 351 is coupled to the main body 301 at an angle of 90 degrees . At this time, as shown in (c) of FIG. 9C, the controller 180 may execute the function of editing the image associated with the 90 degree angle.

In the above description, different functions are performed according to the angle at which the display unit and the main body are coupled. Accordingly, the present invention can provide various functions to the user based on the angle at which the display unit and the main body are combined.
