With this configuration, the operation of the display device 1 according to the first embodiment of the present invention will be described with reference to FIGS.

The user specifies the swivel rotation direction and angle of the display body 100 through the input unit 150. At this time, the control unit 170 controls the UI generating unit 160 to display the user interface screen 161 on the display unit 140, the user the user interface to the swivel rotation direction and angle specified through the input unit 150 This can be confirmed from the screen 161.

The controller 170 receives an operation signal from the input unit 150 and transmits a control signal about a swivel rotation direction and angle designated by the user to the driving circuit unit 311. The driving circuit unit 311 drives the motor 310 based on the control signal from the controller 170, and the rotation shaft 320 rotates in accordance with the driving of the motor 310.

Since the rotation shaft 320 is supported by the rotation shaft support 460, the motor 310 itself rotates by the rotation of the rotation shaft 320 according to the driving of the motor 310. The stand 200 is swiveled by the combined support of the support protrusion 330 and the support groove 225 corresponding thereto.

At this time, accompanied by the swivel rotation of the stand portion 200, the bracket portion 450 coupled to the stand member extension portion 227 also rotates together.

When the stand member extension part 227 is rotated and limited by one end of the guide groove 430 and no further rotation is possible, the stand member extension part 227 contacts the first contact sensor 431a. The first contact sensor 431a generates a signal by contact with the stand member extension part 227. The control unit 170 receives the signal and transmits a control signal to the driving circuit unit 311 to stop the motor 310, thereby stopping the swivel rotation of the stand unit 200. The same principle can be applied to the second contact sensor 431b.

On the other hand, while the stand member extension part 227 is in contact with the first contact sensor 431a, the stand member extension part 227 is rotated to the other end of the guide groove 430 in which the second contact sensor 431b is provided. In this case, the control unit 170 may swivel the stand unit 200 by transmitting a control signal to the driving circuit unit 311 to drive the motor 310.

In addition, the user may manually rotate the display body 100 manually. In this case, the stand unit 200 rotates irrespective of the control unit 170, the driving unit 300, and the contact sensors 431a and 431b, and the stand member extension unit 227 is formed by both ends of the guide groove 430. By limiting the movement, it is possible for the stand portion 200 to swivel between the rotatable angle α. This is because the motor 310 is rotatable about the rotation shaft 320 by the user's force when the driving unit 300 is not driven.

As a result, the display apparatus 1 according to the present invention automates the swivel rotation of the display main body 100 and reduces the frictional force between the components generated during the swivel rotation, thereby easily rotating the stand 200. Can be.

The rotary shaft support part 460a is formed at the lower end of the stand part 200 so as to face the motor accommodating part 223a. The rotary shaft support part 460a may be detachably coupled to the stand member 220 and may be integrally formed with the stand member 220. The rotary shaft support 460a supports the end of the rotary shaft 320a so that the stand 200 is swiveled in accordance with the rotation of the rotary shaft 320a.

With this configuration, the operation of the display device 1 according to the second embodiment of the present invention will be described with reference to FIGS. 6 and 7.

When the user manipulates the input unit 150 to specify the swivel rotation direction and angle, the input unit 150 generates an operation signal. The control unit 170 transmits a control signal to the driving circuit unit 311 based on the operation signal from the input unit 150. The driving circuit unit 311 drives the motor 310 based on the received control signal.

At this time, the motor 310a is supported inside the motor accommodating portion 223a so that the motor 310a itself does not rotate, and the end of the rotating shaft 320a is supported by the rotating shaft supporting portion 460a. Therefore, the rotational force from the motor 310a acts to rotate the stand part 200 via the rotation shaft 320a and the rotation shaft support part 460a.

As described above, the configuration of the drive unit 300 for implementing the swivel mechanism of the stand unit 200 can be various design changes within the scope of the spirit of the present invention.

As described above, according to the present invention, in order to implement the swivel mechanism of the stand portion supporting the display body, by applying a drive unit controlled by the control unit, the swivel rotation of the display body and the stand portion is automated to enhance the user's convenience. A display device is provided.

In addition, through the automatic structure of the swivel rotation, there is provided a display device that can accurately apply the rotation angle desired by the user during the swivel rotation.

In addition, by providing a swivel rotation of the stand portion easily and stably, there is provided a display device that prevents the failure of the parts that can occur when the user grasps the display body and rotates manually.

In addition, there is provided a display apparatus which realizes the above effects and improves the reliability of a product.
