Accordingly, as shown in FIG. 1A , the display apparatus 100 may be rotated from a vertically disposed state to a horizontally disposed state, or rotated from a horizontally disposed state to a vertically disposed state. can

Meanwhile, as shown in FIGS. 1A and 1B , the rotating device 200 may be attached to the stand 300 . Here, the stand 300 may be configured to support the display device 100 and the rotating device 200 . However, this is only an example, and the rotation device 200 may be attached to various positions such as a wall surface (not shown), of course.

Meanwhile, the display device 100 may display an image based on a posture in which the display device 100 is disposed.

For example, it is assumed that the display device 100 is disposed in a horizontal direction (ie, a landscape posture).

In this case, when the image is a horizontal image (ie, a landscape image), the display device 100 may display the horizontal image. Here, the image in the horizontal direction may refer to an image whose horizontal size (ie, width) is greater than the vertical size (ie, height).

Also, when the image is a portrait image (ie, a portrait image), the display device 100 may display the portrait image. Here, the image in the vertical direction may mean an image in which the vertical size is greater than the horizontal size. At this time, since the horizontal size of the display of the display device 100 is greater than the vertical size, when an image in the vertical direction is displayed on the display device 100 arranged in the horizontal direction, blank areas (ie, pillars) are left and right of the image. box) may exist.

As another example, it is assumed that the display device 100 is disposed in a vertical direction.

In this case, when the image is a vertical image, the display device 100 may display the vertical image.

Also, when the image is a horizontally oriented image, the display device 100 may display the horizontally oriented image. At this time, a blank area (ie, a letter box) may exist above and below the image.

In the above example, it has been described that a blank area exists on the display when an image is displayed, but this is only an example. That is, the display device 100 may display images in a layout corresponding to the posture of the display device 100 . That is, when the display device 100 is disposed in the horizontal direction, it may display an image in a layout corresponding to a landscape posture. Also, when the display device 100 is arranged in the vertical direction, it may display an image in a layout corresponding to a portrait posture.

As such, the display device 100 and the rotating device 200 may be implemented as separate devices, and power may be separately applied to these devices.

Accordingly, by attaching the rotation device 200 to the display device 100 without a rotation function, the user can receive various contents through the display device 100 disposed in a desired posture.

Meanwhile, in the present disclosure, while the display device 100 is rotating, a communication connection between the display device 100 and the rotating device 200 is disconnected, the power of the display is turned off, or the power of the rotating device 200 is turned off. When a problem such as being turned on occurs, the rotation of the display device 100 may be stopped.

Then, when the problem is solved and the display device 100 becomes rotatable again, the display device 100 can be rotated in the same direction as before or returned to the posture before rotation. At this time, the display device 100 may display an image corresponding to the posture in which the display device 100 is disposed.

Accordingly, even if the display device 100 and the rotation device 200 are implemented as separate devices, in that an appropriate image is displayed according to the arrangement state of the display device 100, causing user inconvenience. can be prevented.

For example, the display device 100 may transmit a Bluetooth pairing request signal to surroundings of the display device 100 through the communication interface 110 . Also, the rotation device 200 located around the display device 100 may receive the pairing request signal and transmit a response signal to the pairing request signal to the display device 100 . When receiving the response signal, the display device 100 may perform a Bluetooth pairing process between the display device 100 and the rotation device 200 through the communication interface 110 .

The display 120 may display images. Also, the display 120 may display a UI screen for operation of the display device 100 .

To this end, the display 120 may be implemented with various types of displays such as LCD, LED, or OLED.

The processor 130 is electrically connected to the communication interface 110 and the display 120 to control overall operations and functions of the display device 100 .

To this end, the processor 130 may include a central processing unit (CPU) or an application processor (AP), and according to one or more instructions stored in the memory of the display device 100 It can run one or more software programs stored in memory.

First, the processor 130 may control the communication interface 110 so that the display device 100 is communicatively connected to the rotation device 200 by performing a Bluetooth pairing process.

In this case, the processor 130 may control the communication interface 110 to perform a Bluetooth pairing process when the display device 100 is attached to the rotation device 200 .

In addition, the processor 130 performs a Bluetooth pairing process between the display device 100 and the rotating device 200 when a user inputs a Bluetooth pairing command through a touch input to a button provided on the display device 100 or a remote controller. can

Also, the processor 130 may communicate with the display device 100 and the rotation device 200 that has performed the Bluetooth pairing process. Accordingly, the processor 130 may transmit a rotation command to the rotation device 200 through the communication interface 110 .

In this case, the processor 130 may repeatedly transmit rotation commands to the rotation device 200 at regular time intervals while the display device 100 rotates. In addition, the rotation device 200 may transmit a response signal to the rotation command received while performing rotation to the display device 100 .

Also, the processor 130 may transmit various signals related to the operation of the display device 100 to the rotating device 200 through the communication interface 110 . In addition, various signals related to the operation of the rotating device 200 may be received from the rotating device 200 through the communication interface 110 .

Meanwhile, the processor 130 is capable of rotating the display device 100 according to a change in the state after the rotation of the display device 100 is stopped according to the state of at least one of the display device 100 and the rotation device 200. In this state, the rotation direction of the display device 100 can be identified.

Also, the processor 130 may transmit a rotation command for rotating the display device 100 in the identified rotation direction to the rotation device 200 through the communication interface 110 .

Accordingly, the display device 100 is rotated by the rotating device 200, and at this time, an image may be displayed corresponding to a posture in which the display device 100 is disposed.

Specifically, the processor 130 may perform a rotation based on the second posture when the display device 100 rotated from the first posture to the second posture by the rotating device 200 driven according to the rotation command is rotated at a predetermined rotation angle or more. to control the display 120 to display an image.

Here, the first posture may include a posture in which the display device 100 is disposed in a horizontal direction or a posture in which the display apparatus 100 is disposed in a vertical direction.

In this case, the second posture includes a posture in which the display device is disposed in a vertical direction when the first posture is a posture in which the display device 100 is disposed in a horizontal direction, and the first posture includes a posture in which the display apparatus 100 is disposed in a vertical direction. In the case of a posture in which the display device is disposed in a horizontal direction, the posture in which the display device is disposed in a horizontal direction may be included.

Meanwhile, the processor 130 may identify the rotation angle of the display device 100 . Specifically, the processor 130 may identify the rotation angle of the display device 100 based on data obtained through a sensor.

Here, the rotation angle may refer to an angle at which the display apparatus 100 is rotated from the arrangement position before rotation to the arrangement position when the rotation angle is identified.

For example, as shown in FIG. 3A , when the processor 130 identifies the rotation angle while the display apparatus 100 is rotating from the horizontal orientation to the vertical orientation, the rotation angle is determined from the posture (1) of FIG. 3A ( 2) This may mean an angle α through which the display device 100 rotates up to the posture.

In addition, as shown in FIG. 3B, when the rotation angle is identified while the display device 100 rotates from the vertical arrangement direction to the horizontal arrangement direction, the rotation angle is the display device from (1) posture to (2) posture of FIG. 3B ( 100) may mean the rotated angle α.

Meanwhile, the electronic device 100 may include various sensors for identifying a rotation angle of an object.

For example, the display device 100 may include a gyro sensor that measures the angular velocity of an object by converting a Coriolis force generated when the object rotates into an electrical signal. Also, the display device 100 may include an acceleration sensor that measures acceleration of an object in a specific direction. Also, the display device 100 may include an infrared sensor for measuring a distance between objects.

Also, the processor 130 may identify the rotation angle of the display device 100 based on the data obtained through the sensor. Here, since the processor 130 identifies a rotation angle of an object based on data acquired through a gyro sensor, an acceleration sensor, an infrared sensor, and the like, a detailed description thereof will be omitted.

Meanwhile, the processor 130 may identify the rotation angle of the display device 100 based on the rotation time of the display device 100 . Here, the rotation time may mean the elapsed time from the time the display device 100 starts rotating to the time the processor 130 identifies the rotation angle.

To this end, the processor 130 may determine the time when the rotation command is transmitted to the rotation device 200 through the communication interface 110 as the time when the display device 100 starts to rotate. Also, the processor 130 may determine the time when a response signal indicating that the rotation starts according to the rotation command is received from the rotation device 200 as the time when the display device 100 starts to rotate.

For example, as shown in FIG. 4A , when the display device 100 identifies a rotation angle while rotating from the horizontal direction to the newly arranged direction in (1), the processor 130 determines that the display device 100 (1) ), the time N sec elapsed from the start of rotation to the (2) posture can be identified as the rotation time of the display device 100.

In addition, as shown in FIG. 4B, when the display apparatus 100 identifies a rotation angle while rotating from a vertical arrangement posture to a horizontal arrangement posture as shown in (2), the processor 130 determines that the display apparatus 100 (1) The elapsed time N sec from the start of rotation in the posture to the posture (2) can be identified as the rotation time of the display device 100 .

Here, the average rotational speed may refer to a rotational speed of the display apparatus 200 when the display apparatus 100 rotates the rotation apparatus 200 according to a rotation command.

To this end, the display device 100 may include information about the average rotational speed. In this case, information on the average rotational speed may be stored in the display device 100 based on information received from the rotation device 200 or stored in the display device 100 based on a user input.

Specifically, the processor 130 calculates [the time the display device 100 is rotated X (the angle required for the display device 100 to rotate / the time required for the display device 100 to rotate)] of the display device 100. It can be identified by the angle of rotation.

Here, the angle required to rotate the display device 100 and the time required for the display device 100 to rotate are the display device 100 when the rotation device 200 normally rotates the display device 100 according to a rotation command. ) may mean the rotation angle and the time required for the display device 100 to rotate.

To this end, the display device 100 may include information about an angle required for rotation of the display device 100 and a time required for rotation of the display device 100 . In this case, information about the angle required to rotate and the time required to rotate may be stored in the display device 100 based on information received from the rotation device 200 or stored in the display device 100 based on a user input. there is.

Based on the information about the rotation angle can be identified.

Further, the processor 130 may control the display 120 to display an image corresponding to the second posture when the rotation angle of the identified display device 100 is greater than or equal to a predetermined rotation angle.

Here, the predetermined angle may be an intermediate value of an angle rotated to be disposed from the first posture to the second posture, that is, 45 degrees. However, this is only an example, and may be one of values (eg, 30 degrees, 60 degrees, etc.)

For example, as shown in FIG. 5A, the case where the display device 100 rotates from the horizontal arrangement direction to the vertical arrangement direction according to the order (1) -> (2) -> (3) and the preset angle is 45 degrees Assume.

In this case, when the rotation angle of the display device 100 is less than 45 degrees ((1) -> (2)), the processor 130 identifies that the rotation angle of the display device 100 is less than 45 degrees, and horizontally arranges The display 120 may be controlled to display an image corresponding to the direction.

On the other hand, when the rotation angle of the display device 100 is 45 degrees or more ((2) -> (3)), the processor 130 identifies the rotation angle of the display device 100 as being 45 degrees or more, and the vertical arrangement posture. The display 120 may be controlled to display an image corresponding to .

Meanwhile, in the case of FIG. 5B, since only the direction in which the display device 100 rotates in FIG. 5A is reversed, a detailed description thereof will be omitted.

In this way, the display device 100 according to an embodiment of the present disclosure may display an image corresponding to a post-rotation arrangement posture based on a rotation angle of the display device 100 while the display is rotating. Accordingly, the display device 100 can prevent a case where the arrangement posture of the display device 100 and the image displayed on the display 120 do not correspond to each other, and can provide a user with a natural experience in image switching. there is.

Hereinafter, a method of rotating the display device 100 will be described in more detail with reference to FIG. 6 .

6 is a diagram for explaining a method of rotating a display device according to an embodiment of the present disclosure.

First, while an image is displayed on the display 120, the processor 130 may receive a user input for rotating the display apparatus 100 disposed in the first posture to the second posture (S610).

Meanwhile, an image displayed on the display 120 may be an image corresponding to a posture in which the display apparatus 100 is disposed. That is, when the display device 100 is disposed in the first posture, the processor 130 may control the display 120 to display an image corresponding to the first posture, and the display apparatus 100 in the second posture. When arranged as , the display 120 may be controlled to display an image corresponding to the second posture.

Meanwhile, the processor 130 may receive a user input for rotating the display device 100 disposed in the first posture to the second posture. Here, the user input may be input in various ways, such as remote control operation, voice recognition, and touch input to buttons provided in the display device 100 .

Further, when a user input for rotating the display apparatus 100 disposed in the first posture to the second posture is received (S610-Y), the processor 130 sends a rotation command through the communication interface 110 to the rotating device ( 200) (S620).

In this case, when a rotation command is received from the display device 100, the rotation device 200 may rotate the display device 100 according to the received rotation command.

Meanwhile, while the display device 100 rotates, rotation of the display device 100 may be stopped according to a state of at least one of the display device 100 and the rotating device 200 .

Here, the state of at least one of the display device 100 and the rotating device 200 refers to a state in which the power of at least one of the display 120 and the rotating device 200 is turned off and the display device 100 and the rotating device 200 ) may include at least one of disconnected states.

For example, referring to FIG. 7 , when the rotation of the display device 100 is stopped, both the display 120 and the rotation device 200 are powered on while the display device 100 and the rotation device 200 When the connection between them is disconnected (Case 1), when the power of the display 120 is off and the power of the rotating device 200 is on (Case 2), while the power of the display 120 is on, This may be a case where the power of the rotating device 200 is turned off (Case 3) and a case where both the display 120 and the rotating device 200 are turned off (Case 4).

First, as in Case 1, when the connection between the display device 100 and the rotation device 200 is disconnected, driving of the rotation device 200 may be stopped.

Specifically, while the display device 100 rotates, a communication connection between the display device 100 and the rotating device 200 may be disconnected. In this case, the rotation device 200 may detect that the communication connection with the display device 100 is disconnected. And, when it is detected that the communication connection is disconnected, the rotation device 200 may stop driving.

Also, as in Case 2, when the power of the display 120 is turned off, the processor 130 transmits a control command for stopping the driving of the rotating device 200 to the rotating device 200 through the communication interface 110. And, based on the transmitted control command, driving of the rotating device 200 may be stopped.

In addition, as in Case 3 and Case 4, driving of the rotating device 200 may be stopped as the power of the rotating device 200 is turned off.

As described above, in Case 1, Case 2, Case 3, and Case 4, rotation of the display device 100 may be stopped as driving of the rotating device 200 is stopped.

Meanwhile, the processor 130 may identify that the rotation of the display device 100 is stopped (S630).

For example, the processor 130 may identify that rotation of the display apparatus 100 has stopped based on data obtained through a sensor. Specifically, the processor 130 may identify the rotation angle of the display device 100 at regular time intervals based on data acquired through a sensor while the display device 100 is rotating. Further, the processor 130 may identify that rotation of the display device 100 has stopped when the identified rotation angle of the display device 100 does not change.

Also, the processor 130 may identify whether the rotation of the display device 100 has stopped based on information about the state of at least one of the display device 100 and the rotating device 200 .

Specifically, if the processor 130 identifies that the power of the display 120 is turned off, it can identify that the rotation of the display apparatus 100 has stopped.

Also, when it is identified that the rotation device 200 is turned off, the processor 130 may identify that the rotation of the display device 100 is stopped. In this case, when the communication connection between the display device 100 and the rotating device 200 is disconnected, and then, when a signal requesting a communication connection is not received from the rotating device 200, the processor 130 may use the rotating device 200 ) can be identified as being powered off.

Also, when it is identified that the communication connection between the display device 100 and the rotation device 200 is disconnected, the processor 130 may identify that the rotation of the display device 100 is stopped. In this case, since the power is not turned off, the rotation device 200 may transmit a communication request signal or a response signal to the display device 100 when the communication connection with the display device 100 is disconnected. Accordingly, the processor 130 determines whether or not the power of the rotation device 200 is turned off according to whether a signal is received from the rotation device 200 after the communication connection between the display device 100 and the rotation device 200 is disconnected. , it is possible to identify whether the communication connection between the display device 100 and the rotation device 200 is disconnected.

Further, when it is identified that the rotation of the display device 100 is stopped (S630-Y), the processor 130 may identify the rotation angle of the display device 100 corresponding to the stopped time point (S640).

Meanwhile, the processor 130 may identify whether the display device 100 is rotatable as the state of at least one device changes (S650).

Specifically, after the rotation of the display device 100 is stopped as the connection between the display device 100 and the rotation device 200 is disconnected, the processor 130 controls the communication between the display device 100 and the rotation device 200. When the connection is performed, it may be identified that the display device 100 is rotatable.

Further, the processor 130 may identify the display device 100 as rotatable when the power of the display 120 is turned on after the rotation of the display device 100 is stopped as the power of the display 120 is turned off. can

Further, the processor 130 may perform a reconnection between the display device 100 and the rotation device 200 when the power is turned on again after the rotation of the display device is stopped as the power of the rotation device 200 is turned off. Device 100 may be identified as being rotatable.

In addition, after the rotation of the display device 100 is stopped as the power of the display 120 and the power of the rotation device 200 are turned off, the processor 130 turns the power of the display 120 on again and the display device ( 100) and the rotation device 200, which is turned on again, are reconnected, it can be identified that the display device 100 is in a rotatable state.

To this end, the processor 130 may identify whether reconnection between the display device 100 and the rotation device 200 has been performed. That is, after the communication connection between the display device 100 and the rotating device 200 is disconnected, the display device 100 and the rotating device 200 according to a communication connection request signal transmitted from the display device 100 or the rotating device 200. ) can attempt to establish a communication connection between them. Accordingly, the processor 130 may identify that reconnection has been performed when the communication connection is successful.

Also, when the display device 100 is identified as rotatable (S650-Y), the processor 130 determines the rotation direction of the display device 100 based on the identified rotation angle and the attitude of the display device 100 before rotation. It can be identified (S660).

In detail, the processor 130 may identify a rotation direction for disposing the display apparatus 100 in the first posture as the rotation direction of the display apparatus 100 when the identified rotation angle is less than the preset angle. In this case, since the first posture is the posture in which the display apparatus 100 is disposed before rotation, the processor 130 may identify the rotation direction as the opposite direction to the rotation direction of the display apparatus 100 .

Also, when the identified rotation angle is greater than or equal to the preset angle, the processor 130 may identify a rotation direction for disposing the display apparatus 100 in the second posture. In this case, since the second posture is a posture in which the display apparatus 100 is disposed after rotation, the processor 130 may identify the rotation direction as the direction in which the display apparatus 100 rotated.

Meanwhile, this is only an example, and the processor 130 may identify the rotation direction of the display device 100 as the direction in which the display device 100 was rotating. Specifically, when the rotation of the display apparatus 100 is stopped while rotating from the first posture to the second posture, the processor 130 sets the rotation direction for disposing the display apparatus 100 in the second posture to the display apparatus ( 100) can be identified by the direction of rotation.

Also, the processor 130 may transmit a rotation command for rotating the display device 100 in the identified rotation direction to the rotation device 200 through the communication interface 110 (S670).

Also, the rotation device 200 that has received the rotation command may rotate the display device 100 in the identified direction. Accordingly, the display device 100 may be rotated in the rotation direction identified by the rotation device 200 .

After rotation, the processor 130 may control the display 120 to display an image based on the posture in which the display apparatus 100 is disposed (S680).

Specifically, when the display device 100 is rotated to the first posture, the processor 130 may control the display 120 to display an image corresponding to the first posture. Also, when the display apparatus 100 is rotated to the second posture, the processor 130 may control the display 120 to display an image corresponding to the second posture.

In this way, when the display device 100 according to an embodiment of the present disclosure stops rotating due to a problem such as power off of the display or rotation device 200 or disconnection of a communication connection, the problem is solved and the display device operates. When it becomes rotatable, rotation may be performed again according to the identified rotation direction. In this way, the user's convenience can be increased in that the problem that the rotation of the display apparatus 100 is stopped can be solved without a user's separate manipulation.

In addition, in that the display apparatus 100 according to an embodiment of the present disclosure displays an image based on a posture in which the display is disposed after rotation, the display apparatus 100 is configured according to a posture in which the display apparatus 100 is disposed. , the image can be displayed to correspond thereto. In this way, in that an appropriate image is displayed according to the arrangement state of the display device 100, it is possible to prevent a case in which user's inconvenience is caused.

8A and 8B are diagrams for explaining rotation of a display device in which rotation is stopped according to an embodiment of the present disclosure to an arrangement posture before rotation.

First, in the case of FIG. 8A , while the display apparatus 100 disposed in the horizontal direction is rotating in the vertical direction, it is assumed that the rotation is stopped, and the preset angle is 45 degrees.

In this case, as shown in FIG. 8A , rotation of the display device 100 may be stopped due to the power of the rotating device 200 being turned off or the connection between the display device 100 and the rotating device 200 being disconnected. can

At this time, as shown in (1) and (2) of FIG. 8A, when the clockwise rotation of the display device 100 is stopped, the processor 130 can identify the rotation angle corresponding to the stopped time as 20 degrees. there is.

Then, when the display device 100 is identified as rotatable again, the processor 130 can identify the rotation direction of the display device 100 . At this time, since the rotation angle (= 20 degrees) corresponding to the stopped time is less than the preset angle (= 45 degrees), the processor 130 changes the rotation direction of the display device 100 to the direction for arranging the display device 100 in a horizontal position. can be identified by Also, the processor 130 may transmit a rotation command for rotating the display device 100 to the rotation device 200 so that the display device 100 is disposed in the horizontal direction.

Accordingly, as shown in (3) and (4) of FIG. 8A, the display device 100 may be rotated counterclockwise by the rotating device 200 and disposed in a horizontal direction.

In this case, since the display device 100 has not been rotated more than a predetermined angle at the time when the display device 100 is stopped, the display 120 displays an image corresponding to the posture before the display device 100 is rotated, that is, the posture disposed in the horizontal direction. may be displayed continuously.

Meanwhile, in the case of FIG. 8B, since only the direction in which the display device 100 rotates in FIG. 8A is reversed, a detailed description thereof will be omitted.

9A and 9B are diagrams for explaining rotation of a display device in which rotation is stopped according to an embodiment of the present disclosure to a disposition posture after rotation.

First, in the case of FIG. 9A , while the display apparatus 100 arranged in the horizontal direction rotates in the vertical direction, it is assumed that the rotation is stopped, and the preset angle is 45 degrees.

In this case, as shown in FIG. 9A , rotation of the display device 100 is stopped due to the power of the rotation device 200 being turned off or the connection between the display device 100 and the rotation device 200 being disconnected. can

At this time, as shown in (1) and (2) of FIG. 9A, when the clockwise rotation of the display device 100 is stopped, the processor 130 identifies the rotation angle corresponding to the stopped time as 60 degrees. can

Then, when the display device 100 is identified as rotatable again, the processor 130 can identify the rotation direction of the display device 100 . At this time, since the rotation angle (= 60 degrees) corresponding to the point of interruption is less than the predetermined angle (= 45 degrees), the processor 130 changes the rotation direction of the display device 100 to the direction to be placed in the vertical direction. can be identified by Also, the processor 130 may transmit a rotation command for rotating the display device 100 to the rotation device 200 so that the display device 100 is disposed in the vertical direction.

Accordingly, as shown in (3) and (4) of FIG. 9A , the display device 100 may be rotated clockwise by the rotating device 200 and disposed in a vertical direction.

In this case, the display 120 may display an image corresponding to the rotated posture of the display device 100, that is, the vertically disposed posture. Specifically, the display 120 displays an image corresponding to a posture disposed in the horizontal direction until the rotation angle of the display device 100 is less than a predetermined angle (=45 degrees), and the rotation angle of the display device 100 An image corresponding to a posture disposed in the vertical direction may be displayed from when is greater than a predetermined angle (=45 degrees).

Meanwhile, in the case of FIG. 9B, since only the rotation direction of the display device 100 in FIG. 9A is opposite, a detailed description thereof will be omitted.

10A and 10B are diagrams for explaining rotation of a display device whose rotation is stopped when the power of the display is turned off according to an embodiment of the present disclosure.

In the case of FIGS. 10A and 10B , it is assumed that the rotation is stopped while the display apparatus 100 rotates in the vertical direction from the horizontal position, and the predetermined angle is 45 degrees.

In this case, as illustrated in FIGS. 10A and 10B , rotation of the display device 100 may be stopped due to a reason such as when the power of the display 120 is turned off. Also, since the power of the display 120 is turned off, an image may not be displayed on the display 120 .

At this time, as shown in (1) and (2) of FIG. 10A, when the clockwise rotation of the display device 100 is stopped, the processor 130 identifies the rotation angle corresponding to the stopped time as 20 degrees. can

Then, when the power of the display 120 is turned on and the display device 100 is identified as rotatable again, the processor 130 can identify the rotation direction of the display device 100 .

At this time, since the rotation angle (=20 degrees) corresponding to the stopped time is less than the preset angle (=45 degrees), the processor 130 changes the rotation direction of the display device 100 to the horizontal direction, like path 1010. It can be identified as the direction to be placed in. Also, the processor 130 may transmit a rotation command for rotating the display device 100 to the rotation device 200 so that the display device 100 is disposed in the horizontal direction. Accordingly, the display device 100 may be rotated in a counterclockwise direction by the rotating device 200 and disposed in a horizontal direction.

On the other hand, even when the rotation angle (= 20 degrees) corresponding to the stopped time is less than the preset angle (= 45 degrees), as in path 1020, the processor 130 sets the rotation direction of the display device 100 to the display device (= 45 degrees). 100) can be identified as a direction to be arranged in the vertical direction, which is the direction in which it was rotated. Also, the processor 130 may transmit a rotation command for rotating the display device 100 to the rotation device 200 so that the display device 100 is disposed in the vertical direction. Accordingly, the display device 100 may be rotated clockwise by the rotating device 200 and disposed in a vertical direction.

On the other hand, when the display device 100 operates along the path 1020, after the power of the display 120 is turned on, the display 120 displays when the rotation angle of the display device 100 is less than a preset angle (=45 degrees). Images corresponding to postures disposed in the horizontal direction may be displayed until , and images corresponding to postures disposed in the vertical direction may be displayed when the rotation angle of the display device 100 is equal to or greater than a predetermined angle (=45 degrees). .

Meanwhile, as shown in (1) and (2) of FIG. 10B, when the clockwise rotation of the display device 100 is stopped, the processor 130 may identify the rotation angle corresponding to the stopped time as 60 degrees. there is.

Then, when the power of the display 120 is turned on and the display device 100 is identified as rotatable again, the processor 130 can identify the rotation direction of the display device 100 . At this time, since the rotation angle (= 60 degrees) corresponding to the point of interruption is equal to or greater than the preset angle (= 45 degrees), the processor 130 changes the rotation direction of the display device 100 to the direction for being arranged in the vertical direction. can be identified by Also, the processor 130 may transmit a rotation command for rotating the display device 100 to the rotation device 200 so that the display device 100 is disposed in the vertical direction. Accordingly, the display device 100 may be rotated clockwise by the rotating device 200 and disposed in a vertical direction.

In this case, even when the power of the display 120 is turned on, the processor 130 does not display an image until the rotation is completed, and after the rotation is completed, the processor 130 controls the display 120 to display an image corresponding to the vertical direction. You can control it.

However, this is only an example, and the processor 130 may control the display 120 to display an image while rotating when the power of the display 120 is turned on.
