Abstract

A wearable display device is disclosed, which includes: a frame; a display unit configured to show an image in at least a partial area thereof and positioned in front of a user'"'"'s eye in a first mode; a main unit coupled to the frame; and a hinge disposed at a coupling point of the display unit and the main unit to enable a rotation of the display unit, where the display unit is rotatable about the hinge by at least 180 degrees. With the device disclosed herein, it possible to prevent malfunctioning and damage even when the device is worn for extended periods, and it is also possible to resolve the problem of the wearable display device obstructing the field of vision when not in use.

Claims

1. A wearable display device comprising:

a frame;

a display unit configured to show an image in at least a partial area thereof and positioned in front of a user'"'"'s eye in a first mode;

a main unit coupled to the frame;

a hinge disposed at a coupling point of the display unit and the main unit to enable a rotation of the display unit;

a detector part configured to detect a dangerous condition for a user; and

a rotation control part configured to automatically rotate the display unit if the detector part detects the dangerous condition for the user,

wherein the display unit is rotatable about the hinge by at least 180 degrees, and

wherein the detector part is deactivated if the user'"'"'s movement speed is equal to or lower than a preset threshold speed or the user is located indoors.

2. The wearable display device of claim 1, wherein the display unit is rotated in a second mode to be placed in contact with the main unit or in proximity with the main unit within a preset distance.

3. The wearable display device of claim 2, wherein the display unit and the main unit are disposed orthogonally in the first mode, and the display unit is rotated by approximately 270 degrees in the second mode.

4. The wearable display device of claim 2, wherein the main unit comprises an interface for control.

5. The wearable display device of claim 4, wherein the display unit is placed in contact with at least the interface of the main unit when the display unit is placed in contact with the main unit by the rotation.

6. A wearable display device comprising:

a frame;

a main unit coupled to the frame;

a display unit coupled to the main unit, the display unit configured to show an image in at least a partial area thereof and positioned in front of a user'"'"'s eye in a first mode;

a hinge disposed at a coupling point of the display unit and the main unit to enable a rotation of the display unit;

a detector part configured to detect a dangerous condition for a user; and

a rotation control part configured to automatically rotate the display unit if the detector part detects the dangerous condition for the user,

wherein the display unit is rotated to be placed in contact with the main unit or in proximity with the main unit within a preset distance, and

wherein the detector part is deactivated if the user'"'"'s movement speed is equal to or lower than a preset threshold speed or the user is located indoors.

7. The wearable display device of claim 6, wherein the hinge enables the display unit to rotate 270 degrees.

8. The wearable display device of claim 6, wherein the main unit comprises an interface for control.

9. A wearable display device comprising:

a frame;

a main unit coupled to the frame;

a hinge coupled to the frame;

a display unit coupled to the hinge, the display unit configured to show an image in at least a partial area thereof and positioned in front of a user'"'"'s eye during use;

a detector part configured to detect a dangerous condition for a use; and

a rotation control part configured to automatically rotate the display unit if the detector part detects the dangerous condition for the user;

wherein the display unit is capable of rotating at least 180 degrees by way of the hinge, and

wherein the detector pert is deactivated if the user'"'"'s movement seed is equal to or lower than a preset threshold speed or the user is located indoors.

10. The wearable display device of claim 9, wherein the frame comprises a first support part and a second support part opposite the first support part for wearing on a user'"'"'s head, and wherein the main unit is coupled to the first support part and the display unit is coupled to the second support part.

11. The wearable display device of claim 10, wherein the first support part is worn on the user'"'"'s left ear and the second support part is worn on the user'"'"'s right ear.

12. A wearable display device comprising:

a frame;

a main unit coupled to the frame;

a display unit configured to show an image in at least a partial area thereof;

a hinge for rotating the display unit;

a detector part configured to detect a dangerous condition for a use; and

a rotation control part configured to automatically rotate the display unit if the detector part detects the dangerous condition for the user,

wherein the display unit is capable of rotating at least 180 degrees between a position in front of a user'"'"'s eye to the main unit while the wearable display unit is worn by the user, and

wherein the detector part is deactivated if the user'"'"'s movement seed is equal to or lower than a preset threshold speed or the user is located indoors.

13. The wearable display device of claim 12, wherein the display unit comprises a camera configured to receive input of an image in front of the user'"'"'s eye while the wearable display unit is worn.
