a second tilting stand received in the supporting stand, and being configured to be pivotable relative to the first sliding stand, the display panel connected to the second tilting stand while being rotatable relative to the second tilting stand; and
a rotating apparatus comprising a connecting assembly, the connecting assembly comprising a belt, the belt urging the connecting assembly to rise or fall, wherein the rotating apparatus is configured to allow the display panel to be rotated in a predetermined plane and simultaneously rise or fall along the connecting assembly.
16. The display device of claim 15 , wherein the rotating apparatus comprises a first spindle assembly and a second spindle assembly, the first spindle assembly configured to synchronously rotate with rotation of the display panel, the second spindle assembly configured to synchronously rotate with the rotation of the first spindle assembly and cause the display panel to simultaneously rise or fall.
17. The display device of claim 16 , wherein the second spindle assembly comprises a second spindle and a rotatable block threadedly engaged to the second spindle, and the rotatable block is non-rotatable relative to the second spindle.
18. The display device of claim 17 , wherein the second spindle assembly further comprises a static block and a connecting line, the static block comprises a pulley wheel, the rotatable block is connected to one end of the connecting line, the other end of the connecting line is fixed to the supporting stand, and a section of the connecting line is movably received over a top of the pulley wheel of the static block; and when the rotatable block rotates according to the second spindle in a first direction, the connecting line wraps around the rotatable block and the second spindle assembly rises; and when the rotatable block rotates according to the second spindle in a second direction opposite to the first direction, the connecting line unwraps from the rotatable block and the second spindle assembly falls.
19. The display device of claim 18 , wherein the supporting stand comprises a first side plate, a second side plate, and a third side plate, the first side plate and the second side plate are located at two opposite sides of the supporting stand, the third side plate interconnects the first side plate and the third side plate, a stopping protrusion inwardly extends from the third side plate of the supporting stand, and one end of the connecting line is fixed to the stopping protrusion of the supporting stand.
