5. The display device of claim 2 , wherein the supporting unit includes a hollow pillared structure, the linking unit is disposed in the hollow pillared structure, and the fixing mechanism passes through the hollow pillared structure and the linking unit.

6. The display device of claim 1 , wherein the linking unit includes a limiting groove, the supporting unit includes a limiting unit disposed in the limiting groove to restrict the linking unit moving along and relatively to the support unit between a first position and a second position; wherein the first position is where the supporting positioning portion connects to the first linking positioning portion, the second position is where the supporting positioning portion connects to the second linking positioning portion.

7. The display device of claim 6 , wherein the linking unit further includes a stop end, when the linking unit moves to the first position, the stop end contacts the supporting unit and prevents the linking unit from moving forward, and when the linking unit moves to the second position, the limiting unit contacts one end of the limiting groove.

8. The display device of claim 1 , wherein the receiving portion of the display module housing is at bottom of the display module housing.

9. The display device of claim 1 , further comprising a base having a base opening formed thereon, wherein when the linking unit extends out the second length from the receiving portion, the part of the linking unit extended out from the receiving portion is disposed in the base opening to connect the base and the display module housing; when the linking unit extends out the first length from the receiving portion, the base separates from the display module housing.

10. The display device of claim 1 , wherein the supporting unit further includes a supporting rib, the linking unit has a linking rib, and the linking rib is disposed inside the supporting rib.

11. A support module, for supporting an object, the support module comprising:

a supporting unit, having a supporting positioning portion;

a linking unit, having a first linking positioning portion and a second liking positioning portion, wherein the supporting positioning portion is selectively connected to one of the first linking positioning portion and the second linking positioning portion;

a fixing mechanism for connecting the supporting unit and the linking unit, wherein the fixing mechanism is a screw, the supporting positioning portion includes a first hole and a third hole, the first linking positioning portion includes a first threaded hole, and the second linking positioning portion includes a second threaded hole, the screw passes through the first hole, selectively fixes with one of the first threaded hole and the second threaded hole, and passes through the third hole in sequence;

wherein when the supporting positioning portion connects to the first linking positioning portion, the linking unit extends out a third length from the supporting unit; when the supporting positioning portion connects to the second linking positioning portion, the linking unit extends out a fourth length from the supporting unit, and the fourth length is greater than the third length.

12. The support module of claim 11 , wherein the linking unit includes a limiting groove, the supporting unit includes a limiting unit disposed in the limiting groove to restrict the linking unit moving along and relatively to the support unit between a first position and a second position; the first position is where the supporting positioning portion connects to the first linking positioning portion, the second position is where the supporting positioning portion connects to the second linking positioning portion.

13. The support module of claim 11 , wherein the support unit further includes a guiding unit, the linking unit further includes a guiding groove, and the guiding unit moves in the guiding groove.

14. A display device, comprising:

a display module;

a display module housing, having a substantially flat rear surface and a receiving portion, the receiving portion formed between the display module and the rear surface;

a supporting unit, disposed in the receiving portion, the supporting unit connected to the display module, the supporting unit having supporting positioning portion; and

a linking unit, having a first linking positioning portion and a second linking positioning portion;

wherein when the supporting positioning portion connects to the first linking positioning portion, the linking unit extends out a third length from the supporting unit, thereby the substantially flat rear surface stays close to a wall surface in parallel; when the supporting positioning portion connects to the second linking positioning portion, the linking unit extends out a second length from the receiving portion and the second length is greater than the first length, the linking unit can be totally received in the receiving portion.
