5. The display apparatus of claim 4 , wherein one end of the elastic member is connected to the fixing link, and another end of the elastic member is connected to the limiting link.
6. The display apparatus of claim 2 , wherein the link guide portion includes the sloped surface which guides the limiting link to move between the first position and the second position as the display panel rotates.
7. The display apparatus of claim 6 ,
wherein the link body is slidably coupled to the fixing link.
8. The display apparatus of claim 7 , wherein the link guide portion includes a link guide groove that is maximally depressed forward at a location of the guide protrusion when the display panel is in the first orientation and minimally depressed forward at a location of the guide protrusion when the display panel is in the second orientation.
9. The display apparatus of claim 8 , wherein the link guide portion is configured to:
guide the limiting link from the first position to the second position when the display panel rotates from the first orientation to the second orientation; and
guide the limiting link from the second position to the first position when the display panel rotates from the second orientation to the first orientation.
10. The display apparatus of claim 7 , wherein the link guide portion comprises a link guide protrusion that is minimally protruded backward when the display panel is in the first orientation and maximally protruded backward when the display panel is in the second orientation.
11. The display apparatus of claim 7 , wherein when the limiting protrusion is caught into the limiting groove, a downward movement range of the display panel is limited within a first range, and
when the limiting protrusion is spaced from the limiting groove so as not to be caught in the limiting groove, the limitation of the downward movement range of the display panel is limited within a second range that comprises the first range.
12. The display apparatus of claim 1 , wherein the support stand comprises a reinforcing plate adjacent to a rear surface of the support stand inside the support stand, and configured to reinforce a strength, and
wherein the limiting groove is defined by the reinforcing plate.
13. A display stand comprising:
a support bracket configured to support a display panel and rotate between a first orientation and a second orientation, wherein the support bracket comprises a sloped surface;
a support arm configured to support the support bracket and comprising a limiting link; and
a support stand configured to slidably support the support arm within a first vertical range based on the limiting link being in a first position and to slidably support the support bracket within a second vertical range based on the limiting link being in a second position,
wherein the first vertical range is different than and comprises the second vertical range, and
wherein the limiting link comprises:
a guide protrusion in contact with a link guide portion of the support bracket and configured to slide along the link guide portion to guide the limiting link to move between the first position and the second position as the display panel rotates;
a link body extending from the guide protrusion; and
a limiting protrusion extending from the link body, and configured to be positioned capable of contacting a limiting groove of the support stand or be spaced from the limiting groove based on a position of the guide protrusion.
14. The display stand of claim 13 , wherein the limiting link is configured to move along a horizontal direction relative to the support stand based on the support bracket rotating between the first orientation and the second orientation.
15. The display stand of claim 14 , wherein the support stand comprises a reinforcing plate which defines a groove.
16. The display stand of claim 15 , wherein the limiting link is offset from the groove along a vertical direction based on the support bracket being in the first orientation, and
wherein the limiting link overlaps the groove along the vertical direction based on the support bracket being in the second orientation.
17. The display stand of claim 16 , wherein the limiting link is configured to contact a lower surface of the groove based on the support arm being positioned at a lower end of the second vertical range while the support bracket is in the second orientation.
18. A method of limiting vertical motion of a support bracket with respect to a support stand, the method comprising:
allowing the support bracket to vertically move along the support stand within a first vertical range based on the support bracket being in a first orientation;
rotating the support bracket from the first orientation to a second orientation;
sliding a guide protrusion of a support arm provided between the support bracket and the support stand, along a sloped surface of the support bracket as the support bracket rotates from the first orientation to the second orientation; and
moving a limiting protrusion of the support arm into a limiting groove of the support stand as the guide protrusion slides along the sloped surface to limit vertical movement of the support bracket to a second vertical range,
wherein the first vertical range is different than and comprises the second vertical range, and
wherein the guide protrusion and the limiting protrusion extend from a link body of the support arm.
19. The method of claim 18 ,
wherein the moving comprises moving the limiting protrusion from a first position that is offset from the limiting groove along a vertical direction, to a second position that overlaps the limiting groove along the vertical direction, based on the support bracket rotating from the first orientation to the second orientation.
