In addition, when the information about the offset between the recording time and the synchronization signal of each content view displayed on the received screen image is received from the spectacles device 200 through the interface unit 130, the controller 140 generates a plurality of information according to the offset. The display 110 or the synchronization signal generator 120 may be controlled to adjust the display timing or the synchronization signal for the content view.

That is, the controller 140 may receive the screen image from the spectacle apparatus 200 or receive information on the offset analyzed by the spectacle apparatus 200, and may display or synchronize the display timing of the plurality of content views using the screen image. You can adjust the signal.

Accordingly, since the display timing of the image or the synchronization signal transmitted to the spectacle apparatus 200 can be finely adjusted using the screen image photographing the actual display screen, an optimal operation effect can be expected.

In addition, the controller 140 calculates a distance between the spectacle apparatus 200 and the display apparatus 100 using the screen image, and at least one of brightness, grayscale, and subtitle size of each of the plurality of content views according to the calculated distance. The display 110 may be controlled to adjust.

In addition, the controller 140 may calculate the distance by using the angle deviation when the screen image transmitted from the spectacle device is an image photographed from multiple cameras.

In addition, the controller 140 may calculate the distance through the left and right side length deviation of the screen image.

The display 110 may be implemented in a form including a display panel (not shown) for displaying a screen and a rotating motor unit (not shown) for rotating the display panel to change the screen direction.

In this case, the control unit 140 calculates the viewing angle of the spectacle device 200 using the screen image received through the interface unit 110, and rotates the display panel (not shown) according to the viewing angle. The motor unit (not shown) may be controlled.
