Display apparatus
A display apparatus including a display; a support arm coupled to a rear of the display to support the display such that the display is rotatable with respect to the support arm, and including a link member configured to move forward and rearward based on the display being rotated with respect to the support arm; and a support stand configured to support the support arm such that the support arm is movable along a vertical direction, and including a cylinder operable to provide a driving force to move the support arm upward along the vertical direction, wherein, when the display is rotated with respect to the support arm, the link member moves rearward, which thereby causes the cylinder to be operated to provide the driving force to move the support arm upward along the vertical direction, and thereby move the display upward along the vertical direction.
1 . A display apparatus comprising:
a display;
a support arm coupled to a rear of the display to support the display such that the display is rotatable with respect to the support arm, and including a link member configured to move forward and rearward based on the display being rotated with respect to the support arm; and
a support stand configured to support the support arm such that the support arm is movable along a vertical direction, and including a cylinder operable to provide a driving force to move the support arm upward along the vertical direction,
wherein, when the display is rotated with respect to the support arm so that the link member moves rearward, the cylinder is thereby operated to provide the driving force to move the support arm upward along the vertical direction so that the display moves upward along the vertical direction.
2 . The display apparatus according to claim 1 , wherein
the display is rotatable with respect to the support arm so as to be positioned in any one of a first orientation in which a long side of the display is disposed horizontally and a second orientation in which the long side is disposed vertically.
3 . The display apparatus according to claim 2 , wherein
the display is rotatable with respect to the support arm in a first direction, and a second direction opposite to the first direction, to be rotated from the first orientation to the second orientation, and from the second orientation to the first orientation.
4 . The display apparatus according to claim 3 , wherein
the display is rotatable from the first orientation to the second orientation by being rotated in the first direction or the second direction at a first angle with respect to the support arm,
the display is rotatable from the second orientation to the first orientation by being rotated in the first direction or the second direction at the first angle with respect to the support arm, and
the support stand is configured so that the cylinder is operable to move the support arm upward along the vertical direction, and thereby move the display upward along the vertical direction, based on the display being rotated in the first direction or the second direction at a second angle with respect to the support arm, the second angle being smaller than the first angle.
5 . The display apparatus according to claim 1 , wherein
the display includes a plurality of guide grooves on a rear surface of the display, each guide groove among the plurality of guide grooves extending longitudinally in an arc shape, and
a depth of each guide groove among the plurality of guide grooves varies along a circumferential direction of the arc shape.
6 . The display apparatus according to claim 5 , wherein
the support arm includes an elastic member elastically biasing the link member forward so that the link member is insertable into a corresponding guide groove among the plurality of guide grooves.
7 . The display apparatus according to claim 1 , wherein
the support stand includes a link bracket configured to:
move upward along the vertical direction based on forward movement of the link member, and
move downward along the vertical direction based on rearward movement of the link member.
8 . The display apparatus according to claim 7 , wherein
the cylinder includes a switch to operate the cylinder to provide the driving force by being pushed, and
the link bracket pushes the switch by moving downward.
9 . The display apparatus according to claim 7 , wherein
the link bracket is configured to move from a first position to a second position lower than the first position based on the rearward movement of the link member, and
the link bracket is configured to move from the second position to the first position based on the forward movement of the link member.
10 . The display apparatus according to claim 7 , wherein
the link member includes a first guide part configured to be connected to the link bracket, and
a lower surface of the first guide part is inclined upward and rearward.
11 . The display apparatus according to claim 10 , wherein
the link bracket includes a second guide part having a guide surface provided to be inclined upward and rearward to correspond to the lower surface of the first guide part.
12 . The display apparatus according to claim 11 , wherein
as the link member moves rearward, at least a portion of the first guide part is inserted into the second guide part, and
as the link member moves forward, at least a portion of the first guide part is withdrawn from the second guide part.
13 . The display apparatus according to claim 7 , wherein
the support stand includes a damping device to reduce an upward and downward moving speed along the vertical direction of the support arm and the link bracket.
14 . The display apparatus according to claim 13 , wherein
the damping device includes:
a moving member to move upward or downward along the vertical direction together with the link bracket;
a guide rail to guide the upward and downward movements of the moving member along the vertical direction; and
a friction member between the moving member and the guide rail to increase a frictional force of the moving member against the guide rail.
