Display apparatus

1. A display apparatus comprising:

a display assembly;

a mounting device on which the display assembly is mounted; and

a rotating shaft for rotating the display assembly, and disposed at a fixed position on the mounting device and the display assembly,

wherein the display assembly is switched between a first mode and a second mode by rotating the display assembly around the rotating shaft,

wherein the rotating shaft remains at a same position on the mounting device and a display of the display assembly when the display assembly is switched between the first mode and the second mode, and

wherein a position of a center of the display assembly changes in a vertical direction based on the display assembly being switched between the first mode and the second mode,

wherein the rotating shaft is biased from the center of the display assembly,

wherein the display apparatus further comprises an elastic device configured to generate an elastic force when the display assembly rotates with respect to the rotating shaft, and

wherein one end of the elastic device is rotatably fixed on the mounting device and the other end of the elastic device is spaced radially from the rotating shaft to be rotatably fixed on a rear surface of the display assembly.

2. The display apparatus of claim 1 , wherein the rotating shaft remains in the fixed position in the first mode and in the second mode.

3. The display apparatus of claim 1 , wherein the rotating shaft is spaced at a first distance from a first horizontal reference axis passing the center of the display assembly, and at a second distance from a first vertical reference axis passing the center of the display assembly, and

wherein the first distance and the second distance are greater than zero.

4. The display apparatus of claim 3 , wherein the first distance is equal to the second distance.

5. The display apparatus of claim 1 , wherein the rotating shaft is spaced at a third distance from a second horizontal reference axis passing the center of the display assembly when the display assembly is in the second mode, and

wherein the second horizontal reference axis is different from a first horizontal reference axis which passes the center of the display assembly when the display assembly is in the first mode.

6. The display apparatus of claim 5 , wherein a first vertical reference axis passing the center of the display assembly when the display assembly is in the first mode is identical to a second vertical reference axis passing the center of the display assembly when the display assembly is in the second mode.

7. The display apparatus of claim 1 , wherein the first mode is a landscape mode in which a horizontal length of the display assembly is longer than a vertical length of the display assembly,

wherein the second mode is a portrait mode in which a vertical length of the display assembly is longer than a horizontal length of the display assembly, and

wherein the center of the display assembly in the landscape mode is higher than the center of the display assembly in the portrait mode.

8. The display apparatus of claim 1 , wherein, the elastic device is disposed in an opposite direction from the center of the display assembly with respect to a direction in which the rotating shaft is biased from the center of the display assembly.

9. The display apparatus of claim 1 , wherein the elastic device is positioned:

at a first elastic position when the display assembly is in the first mode, and

at a second elastic position when the display assembly is in the second mode, and

wherein when the position of the elastic device changes from the first elastic position to the second elastic position, the elastic device passes through a maximum compression position at which the elastic device is compressed to a maximum.

10. The display apparatus of claim 9 , further comprising a damper disposed on a path along which the elastic device moves from the maximum compression position to the second elastic position.

11. The display apparatus of claim 1 , wherein the elastic device is at least one of a gas spring, a hydraulic spring, and a coil spring.

12. A display apparatus comprising:

a mounting device; and

a display assembly mounted on the mounting device, and configured to be switched between a first mode and a second mode by being rotated around a rotating shaft,

wherein the rotating shaft remains at a same position on the mounting device and a display of the display assembly when the display assembly is switched between the first mode and the second mode, and

wherein the rotating shaft is biased in a horizontal direction and a vertical direction from a center of the display assembly,

wherein the display apparatus further comprises:

an elastic device configured to generate an elastic force when the display assembly rotates with respect to the rotating shaft,

wherein one end of the elastic device is rotatably fixed on the mounting device and the other end of the elastic device is rotatably fixed on a rear surface of the display assembly to be adjacent to the rotating shaft.

13. The display apparatus of claim 12 , wherein a position of the rotating shaft in the first mode is identical to a position of the rotating shaft in the second mode.

14. The display apparatus of claim 12 , wherein the rotating shaft is spaced at a first distance from a first horizontal reference axis passing the center of the display assembly and at a second distance from a first vertical reference axis passing the center of the display assembly.

15. The display apparatus of claim 14 , wherein the first distance is equal to the second distance.

16. A display apparatus comprising:

a mounting device; and

a display assembly mounted on the mounting device, and configured to be switched between a first mode and a second mode by being rotated around a rotating shaft,

wherein the display assembly is switched between the first mode and the second mode and a position of a center of the display assembly changes in a vertical direction, by rotating the display assembly around the rotating shaft, and

wherein the rotating shaft remains at a same position on the mounting device and a display of the display assembly when the display assembly is switched between the first mode and the second mode,

wherein the rotating shaft is biased from the center of the display assembly,

wherein the display apparatus further comprises an elastic device configured to generate an elastic force when the display assembly rotates with respect to the rotating shaft, and

wherein one end of the elastic device is rotatably fixed on the mounting device and the other end of the elastic device is spaced radially from the rotating shaft to be rotatably fixed on a rear surface of the display assembly.
