[0091] In addition to the configuration of the rocker switch (70s), the guide member (73) can be moved up and down by the push projection (74). The push projection (74) can be arranged to interfere with the supporter (30). The push projection (74) can be moved downward by its own weight and protrude into the supporter groove (43), and can be moved upward by the supporter (30) inserted into the supporter groove (43).

[0092] The push projection (74) may include a locking portion (74a) and a protrusion (74b). The locking portion (74a) may be positioned above the protrusion (74b) to support the guide member (73). The protrusion (74b) may be provided to protrude from the locking portion (74a) toward the supporter groove (43).

[0093] The support stand (40) may include a through wall (43b) that includes a through hole (43a) through which the protrusion (74b) of the push projection (74) passes. The through hole (43a) may be in communication with the supporter groove (43). The catch (74a) may be caught on the through wall (43b), and the protrusion (74b) received in the through hole (43a) may protrude into the supporter groove (43). Due to the structure in which the catch (74a) is caught on the through wall (43b), the position of the push projection (74) and the guide member (73) supported by the push projection (74) can be fixed without falling below a certain position.

[0094] According to this structure, the protrusion (74b) protruding from the supporter home (43) can be moved upward by the supporter (30), and accordingly, the stopper (71) can be positioned at the unlocking position (ULP).

[0095] That is, when the support stand (40) is coupled to the supporter (30), the stopper (71) can be positioned in the unlocking position (ULP) according to the movement of the push projection (74), so the display module (10) coupled to the stand arm (50, see FIG. 3) can be moved more easily in the up and down direction without separate operation. From the user's perspective, the display module (10) can be moved to the desired position without adjusting a separate locker switch (70s), so satisfaction can be improved.

[0096] With the stopper (71) in the unlocking position (ULP), as shown in FIG. 15, the arm coupling part (55) can be moved upward along the slide groove (45). As the arm coupling part (55) moves, the first slider (47a) and the second slider (47b) can be moved.

[0097] When the arm coupling part (55) coupled to the display module (10) moves up and down along the slide groove (45) with acceleration, it may be difficult for the user to easily adjust the position of the display module (10) they want. To prevent this problem, a holding damper (48) may be mounted inside the support stand (40) to slow down the speed of the arm coupling part (55).

[0098] The holding damper (48) may be a hydraulic damper. The holding damper (48) may include a holding piston (48p), a holding cylinder (48c), and a holding gear (48a). The holding cylinder (48c) may be connected to the holding gear (48a) through the holding piston (48p). The holding damper (48) can smoothly adjust the position of the holding gear (48a) connected to the holding piston (48p) by utilizing the structure of a hydraulic damper inside.

[0099] However, it is not limited to this, and the holding damper (48) may be made of an elastic member. In this way, the structure of the holding damper (48) is sufficient if it is a structure that cushions the speed of the arm joint (55).

[0100] More specifically, as the arm coupling portion (55) moves along the slide groove (45), the second slider (47b), which moves, can be moved up and down while rotating the holding gear (48a) clockwise through the rack gear (47ba). The holding gear (48a) can be moved by engaging with the guide rack gear (49a) of the gear guide (49), which is positioned opposite to the rack gear (47ba) of the second slider (47b) and extends parallel to the slide groove (45).

[0101] As the holding gear (48a) moves in the up and down direction, the length of the holding piston (48p) extending from the holding cylinder (48c) can be adjusted. The holding gear (48a) can be moved by half the distance of the arm coupling (55), and the holding gear (48a) moved upward can further withdraw the holding piston (48p) from the holding cylinder (48c). As the holding piston (48p) is withdrawn from the holding cylinder (48c), the composition of oil or the like inside the holding cylinder (48c) can slow down the withdrawal speed of the holding piston (48p).

[0102] According to this structure, the speed of the second slider (47b) can be slowed down not only when the arm joint (55) is moved upward but also when it is moved downward. According to this structure, the speed of the display module (10), which is movable in the up and down direction along the slide groove (45), can be smoothly relieved, allowing the user to more easily adjust the position of the display module (10), and the durability can be improved by preventing the arm joint (55) from impacting the border wall (45a).

[0103] FIG. 17 is an exploded perspective view of the stopper, guide member, and link member shown in FIG. 13. FIG. 18 is an exploded perspective view of the stopper, guide member, and link member according to one embodiment of the present disclosure.

[0104] Referring to FIG. 17, the guide member (73) may include a connecting shaft (73s) provided to be coupled to the link member (72). The stopper (71) may include a stopper shaft (71s) provided to be coupled to the link member (72).

[0105] The link member (72) may include a coupling hole (72b) arranged on one side for inserting a coupling shaft (73s) and a stopper hole (72a) arranged on the other side for inserting a stopper shaft (71s).

[0106] As the connecting shaft (73s) of the guide member (73) is inserted into the connecting hole (72b) of the link member (72) and the stopper shaft (71s) of the stopper (71) is inserted into the stopper hole (72a) of the link member (72), the link member (72) can rotate the stopper (71) in response to the movement of the guide member (73).

[0107] For example, as shown in FIG. 13, as the guide member (73) is moved upward by the push projection (74), the link member (72) can move the stopper (71) to the unlocking position (ULP). Also, as shown in FIG. 14, as the guide member (73) is moved downward, the link member (72) can move the stopper (71) to the locking position (LP).

[0108] Referring to FIG. 18, unlike the structure of FIG. 17, the guide member (173) may include a coupling hole (173h). The stopper (171) may include a stopper hole (171h).

[0109] The link member (172) may include a coupling shaft (172b) for insertion into a coupling hole (173h) and a stopper shaft (172a) for insertion into a stopper hole (171h). The coupling shaft (172b) may be provided on one side of the link member (172), and the stopper shaft (172a) may be provided on the other side of the link member (172). According to this structure, as described above, the stopper (171) can be moved between an unlocking position (ULP) and a locking position (LP) by the link member (172) as the guide member (173) moves.

[0110] FIG. 19 is a rear perspective view illustrating a state in which a handle according to one embodiment of the present disclosure is withdrawn from a support stand. FIG. 20 is a plan view illustrating when the handle according to one embodiment of the present disclosure shown in FIG. 19 is positioned at a second position.

[0111] Referring to FIGS. 15, 19 and 20, the display device (1) may further include a handle (60) provided on the upper part of the support stand (40). The handle (60) may be coupled to the support stand (40) so as to be pulled upward from the support stand (40).

[0112] The display module (10) may be configured to be movable according to the user's preference. More specifically, the display module (10) may be configured to be moved by the user wherever the user is located to output images, etc. to the user. In order for the display module (10) to be moved, the display module (10) may be moved by a handle (60) that is pulled out from the support stand (40) while the display module (10) is coupled to the support stand (40).

[0113] The handle (60) can be received in a handle groove (41, see FIG. 6) provided on the upper part of the support stand (40). The handle (60) may include a holding portion (61) formed to be held by a user's hand, and an insertion portion (62) extending from both sides of the holding portion (61) toward the support stand (40) so as to be inserted into the support stand (40).

[0114] The handle (60) may be movable between a first position (P1) when the insertion part (62) is inserted deepest into the support stand (40) and a second position (P2) when the insertion part (62) pulls the holding part (61) most far up the support stand (40).

[0115] When the handle (60) is in the first position (P1), if the insertion part (62) is clicked or pushed downward once, the insertion part (62) can be moved toward the handle damper (46) and then slowly moved upward. The position where the holding part (61) of the handle (60) is furthest from the support stand (40) may be when the handle (60) is in the second position (P2).

[0116] The handle damper (46) is provided in pairs to support each insert (62). The handle damper (46) may include a handle piston (46p) and a handle cylinder (46c). As each insert (62) pushes the handle piston (46p) downward, the handle piston (46p) can be inserted into the handle cylinder (46c).

[0117] The oil or fluid inside the handle cylinder (46c) can pull the handle piston (46p) inserted into the handle cylinder (46c) out of the handle cylinder (46c) to push the insertion part (62) upward. In this process, the handle piston (46p) can be gradually pulled out upward of the support stand (40).

[0118] According to this structure, when a user pulls the handle (60) out of the support stand (40), the handle (60) can be pulled out slowly from the support stand (40), thereby mitigating the impact on the handle. In other words, the durability of the handle (60) can be improved. Additionally, since the user can pull the handle (60) out of the support stand (40) with a single click, the display module (10, see FIG. 1) and the support stand (40) can be transported more conveniently.

[0119] When the handle (60) is positioned at the second position (P2), if the holding part (61) and the insertion part (62) are pushed downward, the holding part (61) can be received in the handle groove (41, see FIG. 6) and its position can be fixed.

[0120] According to this structure, the display module (10) can be moved, and at the same time, when the user does not move the display module (10), the handle (60) can be pushed toward the support stand (40), so that the aesthetics can be improved.

[0121] The handle damper (46) is not limited to a hydraulic damper and can be made of an elastic member. Additionally, the handle damper (46) is sufficient if it has a structure that smoothly pulls out the handle (60).

[0122] FIG. 21 is a rear perspective view illustrating a support stand according to one embodiment of the present disclosure tilting a display module.

[0123] Referring to FIG. 21, the display device (1) can be positioned to support the display module (10) even without the support stand (40) being connected to the supporter (30).

[0124] Since the support stand (40) can be rotated on the stand arm (50), the display module (10) can be arranged so that it is inclined toward the rear as it goes upward, and the support stand (40) can be arranged so that it is inclined toward the front as it goes upward, thereby supporting the display module (10) with only the support stand (40).

[0125] As shown in FIG. 21, the mode in which the display module (10) is positioned at an angle on the support stand (40) can be called the tilt mode.

[0126] According to this structure, the user can mount the display module (10) on an inclined support stand (40) at a desired location at a desired moment without the need for a supporter (30) during transport, and view video or images transmitted from the display module (10) or use the processor.

[0127] FIG. 22 is a perspective view illustrating the combination of a stand leg integrally formed on a wall and a support stand according to one embodiment of the present disclosure.

[0128] Referring to FIG. 22, the supporter (130) may be formed integrally with the wall (Wall, W). The insertion projection (133) of the supporter (130) may be formed to face upward, and the support stand (40) may include a supporter groove formed to receive the insertion projection (133) of the supporter (130).

[0129] The insertion projection (133) inserted into the supporter groove can support the support stand (40), and accordingly, the stopper (71) of the locker (70, see FIG. 13) is positioned at the unlocking position (ULP) to allow the stand arm (50), which is arranged to be coupled with the display module (10), to be freely moved up and down along the slide groove (45).

[0130] The effects of this structure are as described above.

[0131] FIG. 23 is a perspective view illustrating a support stand according to one embodiment of the present disclosure.

[0132] Referring to FIG. 23, the support stand (140) may include a push projection (174) provided at the bottom so as to be exposed to the outside instead of a support groove. According to this structure, when the support stand (140) is positioned in a tilt mode as shown in FIG. 21, the protrusion (174b) of the push projection (174) can be pushed by the floor or the like and inserted into the support stand (140).

[0133] As the protrusion (174b) of the push projection (174) is pushed into the support stand (140), the stopper (71) of the locker (70, see FIG. 13) can be positioned in the unlocking position (ULP), so that the user can move the display module (10) and the stand arm (50) directly within the slide groove (145) without adjusting a separate locker switch (70s), etc.
