Abstract

A supporting device is installed between an auxiliary display unit and a main display unit to variously change the position and pose of the auxiliary display unit and a dual display unit having the same are disclosed. The dual display unit includes a main display unit which displays an image, a supporting device which is coupled to the main display unit, and an auxiliary display unit which is installed on the supporting device. The supporting device is configured to adjust the distance between the main display unit and the auxiliary display unit.

Claims

1. A dual display unit comprising:

a stand;

a main display unit non-rotatably fixed to the stand to display an image;

a supporting device which is rotatably coupled to a rear surface of the main display unit; and

an electronic auxiliary display unit which is installed on the supporting device,

wherein the supporting device is configured to adjust a distance between the main display unit and the auxiliary display unit,

wherein the supporting device is rotatably installed such that the auxiliary display unit moves to an upper side and opposite side of the main display unit.

2. The dual display unit according to claim 1, wherein the supporting device is rotatably coupled to the auxiliary display unit such that the auxiliary display unit is capable of being arranged in a landscape view or a portrait view.

3. The dual display unit according to claim 1, wherein the supporting device includes a first supporting member installed on the main display unit and a second supporting member installed on the auxiliary display unit, and the first supporting member and the second supporting member are slidably coupled to each other to adjust the distance between the main display unit and the auxiliary display unit.

4. The dual display unit according to claim 3, wherein the first supporting member includes a guide rail to guide a sliding motion of the second supporting member.

5. The dual display unit according to claim 4, wherein a guide member is installed on an inside of the guide rail to guide the sliding motion of the second supporting member.

6. The dual display unit according to claim 5, wherein at least one fixing protrusion is disposed on any one of the inside of the guide rail, the guide member or a fixing groove coupled to the fixing protrusion, is disposed on the other thereof to fix a position of the guide member.

7. The dual display unit according to claim 5, wherein the first supporting member includes a position determining groove to guide a sliding position of the second supporting member, and a stopper having a position determining protrusion, which is engaged with the position determining groove, is installed on the second supporting member.

8. The dual display unit according to claim 3, wherein the second supporting member includes a hinge portion such that the auxiliary display unit can be tilted forward and backward.

9. The dual display unit according to claim 1, wherein an installation hole compliant with a VESA standard is disposed on a rear surface of the main display unit, and the supporting device is installed through the installation hole.

10. The dual display unit according to claim 9, wherein an installation bracket is coupled to the rear surface of the main display unit through the installation hole, and the installation bracket includes a shaft hole to support the supporting device to rotate with respect to the main display unit.

11. The dual display unit according to claim 10, wherein the installation bracket includes first rotation limiting projections formed at opposite sides of the shaft hole, and the supporting device includes a second rotation limiting projection which is in contact with the first rotation limiting projections to restrict a rotation range of the supporting device.

12. The dual display unit according to claim 1, wherein the supporting device includes a supporting member which connects between the main display unit and auxiliary display unit, and a slide unit which is installed on the main display unit or the auxiliary display unit and guides forward and backward movement of the supporting member to adjust the distance between the main display unit and auxiliary display unit.

13. The dual display unit according to claim 12, wherein the slide unit is rotatably coupled to main display unit or the auxiliary display unit.

14. The dual display unit according to claim 13, wherein the supporting member is rotatably coupled to the main display unit or the auxiliary display unit.

15. The dual display unit according to claim 12, wherein the supporting member includes a hinge portion such that the auxiliary display unit can be tilted forward and backward.

16. The dual display unit according to claim 12, wherein the main display unit includes at least one first rotation limiting projection formed on its rear surface, and the supporting device includes a second rotation limiting projection which is in contact with the first rotation limiting projection to restrict a rotation range of the supporting device.

17. A dual display unit comprising:

a first display unit;

an electronic second display unit;

a stand non-rotatably fixed to the first display unit; and

a supporting device rotatably coupled to a rear surface of the first display unit and the second display unit, the supporting device being capable of providing a range of motion to reposition at least one of the display units such that the viewing configuration is changed as either the first display unit or the second display unit is repositioned along the range of motion of the supporting device, wherein the supporting device is rotatably installed such that the second display moves to an upper side and opposite side of the first display unit.
