The insertion hole (974) may be communicated with the accommodation space of the second pin housing (970). The insertion hole (974) may be communicated with an opening of the first space (964). The insertion holes (974) may be provided in a number corresponding to the number of second pins (960). The side wall (971) of the second pin housing (970) may be named a second side wall (971).

The second pin housing (970) may have a surface (976). The second side wall (971) and the cover (972) may be connected by a second housing guide surface (976) having a curved shape. The second housing guide surface (976) may be convex toward the outside of the second pin housing (970). The second housing guide surface (976) may extend along an edge of the second pin housing (970).

The second pin housing (970) may have a second recessed portion (977). The second recessed portion (977) may be formed by recessing the outer surface of the second side wall (971) inwardly. The second recessed portion (977) may extend toward the cover (972) of the second pin housing (970) and may be opened in the extended direction. The second recessed portion (977) may extend in the insertion direction of the first pin (920). The cover (972) may not cover the second recessed portion (977). The second recessed portion (977) may be recessed in a shape corresponding to the first protrusion (937).

The second connector (950) may have a third pin housing (980). The third pin housing (980) may surround one side of the second pin housing (970). The third pin housing (980) may have a side wall (981) and a bottom (985). The side wall (981) of the third pin housing (980) may be spaced outwardly from the side wall (971) of the second pin housing (970). The side wall (981) of the third pin housing (980) may extend along the perimeter of the side wall (971) of the second pin housing (970). A third space (984) may be formed between the side wall (981) of the third pin housing (980) and the side wall (971) of the second pin housing (970). The side wall (981) of the third pin housing (980) may be lower than the side wall (971) of the second pin housing (970). One side of the third space (984) may be open, and the other side of the third space (984) may block the bottom (985) of the third pin housing (980). The side wall (981) of the third pin housing (980) may be referred to as a third side wall (981).

The upper end of the third side wall (981) may have a third housing guide surface (983) formed convexly. The third housing guide surface (983) may be formed convexly toward the third space (984). The third housing guide surface (983) may extend along the edge of the third side wall (981).

The second protrusion (986) may protrude inwardly from the inner surface of the third side wall (981) toward the third space (984). The second protrusion (986) may be positioned adjacent to the second recessed portion (977) or parallel to the second recessed portion (977) at a position corresponding to the second recessed portion (977). The second protrusion (986) may protrude in a shape corresponding to the first recessed portion (936). The second protrusion (986) may extend in the insertion direction of the first pin (920).

The first connector (910) and the second connector (950) can be coupled to each other. The first pin (920) of the first connector (910) can pass through the insertion hole (974) and be inserted into the first space (964) provided by the second pin (960) to come into contact with the second pin (960). The first pin (920) and the second pin (960) can come into contact with each other and be electrically connected to each other.

The second pin housing (970) can be inserted into the second space (934) provided by the first pin housing (930). When the second pin housing (970) is inserted into the second space (934), the outer surface of the second side wall (971) can slide on the inner surface of the first side wall (931). The first housing guide surface (933) can contact the second side wall (971) or the second housing guide surface (976) to guide the second pin housing (970) to be inserted into the second space (934). The second housing guide surface (976) can contact the first side wall (931) or the first housing guide surface (933) to guide the second pin housing (970) to be inserted into the second space (934). The first side wall (931) can be inserted into a third space (984) between the second side wall (971) and the third side wall (981). The third housing guide surface (983) can be in contact with the first side wall (931) to guide the first side wall (931) to the third space (984).

When the first connector (910) and the second connector (950) are coupled, the second protrusion (986) can be inserted into the first recessed portion (936). The second protrusion (986) can be slid in the insertion direction into the first recessed portion (936). The first protrusion (937) can be inserted into the second recessed portion (977). The first protrusion (937) can be slid in the insertion direction into the second recessed portion (977).

Accordingly, the ease of coupling between the first connector (910) and the second connector (950) is improved, and the problem of the structure being damaged during coupling can be minimized.

Referring to FIG. 13, the second pin (960) may be opened on one side, and a first space (964) into which the first pin (920, see FIG. 12) is inserted may be formed. The second pin housing (970) may accommodate the second pin (960) and provide an insertion hole (974) that is communicated with the opening of the first space (964). The pin cover (973) may cover at least a portion of the second pin (960) around the insertion hole (974). The pin cover (973) may surround a side of the insertion hole (974). The insertion hole (974) may be communicated with the first space (964) in the insertion direction of the first pin (920, see FIG. 12).

The second pin (920) may have a pin side (961) surrounding the first space (964). The upper end of the pin side (961) may be opened toward the insertion hole (974). The pin side (961) may include a cylindrical shape having a first space (964) formed therein and opened upward. The first space (964) may have a shape corresponding to the outer circumferential surface of the pin body (921) of the first pin (920). The pin side (961) may extend in the circumferential direction. The pin side (961) may be formed as a C-type pin having a part cut in the insertion direction of the first pin (920, see FIG. 12) to have a cut space (965) shape.

Accordingly, when the first pin (920, see FIG. 12) is inserted into the first space (964), the first pin (920) comes into contact with the inner surface of the pin side (961), and is inserted into the first space (964) while spreading the pin side (961) radially outward, and can come into contact with the second pin (960) (see FIG. 19).

The second side wall (971) can surround the pin side portion (961) in the circumferential direction. The pin cover (973) can protrude inwardly from the upper inner surface of the second side wall (971) toward the insertion hole (974). The pin cover (973) can protrude radially inwardly from the upper inner surface of the second side wall (971). The pin cover (973) can extend circumferentially along the upper inner surface of the second side wall (971). The width (D1) of the inner surface of the pin cover (973) can be smaller than the width (D2) of the inner surface of the second side wall (971).

The pin cover (973) can cover at least a portion of the upper portion of the pin side portion (961). The pin cover (973) can be placed on the upper portion of the pin side portion (961). The pin cover (973) can overlap at least a portion of the pin side portion (961) in the insertion direction of the first pin (920). The pin cover (973) can cover the upper portion of the pin side portion (961), but may not cover the first space (964).

Before the first pin (920) is inserted into the first space (964), the inner surface of the pin side (961) may overlap the outer surface of the insertion hole (974) or may be arranged inside the outer surface of the insertion hole (974). The width (D31) of the first space (964) or the width (D31) of the inner surface of the pin side (961) may be equal to or smaller than the minimum width (D1) of the insertion hole (974). The width (D32) of the outer surface of the pin side (961) may be larger than the minimum width (D1) of the insertion hole (974). The width (D32) of the outer surface of the pin side (961) may be smaller than the width (D2) of the inner surface of the second side wall (971). The first pin (920, Fig. 12) can come into contact with the second pin (960) after passing through the insertion hole surrounded by the pin cover (973).

Accordingly, when the first pin (920, FIG. 12) is inserted into the first space (964), the first pin (920, FIG. 12) is caught on the upper end of the pin side (961), thereby minimizing the problem of the first pin (920) or the second pin (960) being damaged (see FIG. 19). In addition, since the first pin (920) is inserted without being caught on the pin side (961), the coupling of the first connector (910) and the second connector (950) can be facilitated (see FIG. 19).

The pin cover (973) may have a pin guide surface (975). The pin guide surface (975) may surround the insertion hole (974). The pin guide surface (975) may be formed on the inner circumferential surface of the pin cover (973). The pin guide surface (975) may be formed so that the width of the insertion hole (974) gradually narrows toward the insertion direction of the first pin (920, FIG. 12). The pin guide surface (975) may be formed convexly toward the insertion hole (974).

Accordingly, when the first pin (920, see FIG. 12) passes through the insertion hole (974), the pin guide surface (975) can come into contact with the first pin (920) and guide the first pin (920) to the first space (964) (see FIG. 19). In addition, the coupling of the first connector (910) and the second connector (950) can be facilitated.

Referring to FIG. 14, the upper end of the pin side (961) may have an inclined surface (963) that is formed to be inclined. The inclined surface (963) may be formed to be inclined so that the width of the first space (964) gradually narrows along the insertion direction of the first pin (920, see FIG. 12). The inclined surface (963) may extend inclinedly from the upper end of the pin side (961) toward the inner surface of the pin side (961). The upper end of the inclined surface (963) may be connected to the upper end of the pin side (961), and the lower end of the inclined surface (963) may be connected to the inner surface of the pin side (961). The inclined surface (963) may extend circumferentially along the pin side (961).

The inclined surface (963) may include a portion that overlaps the insertion hole (974) in the insertion direction of the first pin (920, see FIG. 12). The width of the lower portion of the inclined surface (963) may match the width (D31) of the inner surface of the pin side (961). The width (D41) of the lower portion of the inclined surface (963) may be smaller than the width (D1) of the insertion hole (974). The width (D42) of the upper portion of the inclined surface (963) may be larger than the width (D1) of the insertion hole (974).

Referring to FIGS. 15 to 19, the first pin housing (930) can provide a second space (934). The first pin (920) can be placed in the second space (934). The second space (934) can be open on one side. The first pin housing (930) can surround the remaining portion of the second space (934) except for the open side.

The first pin housing (970) can be inserted into the second space (934). When the second pin housing (970) is inserted into the second space (934), the outer surface of the second side wall (971) can slide on the inner surface of the first side wall (931). The first housing guide surface (933) can contact the second side wall (971) or the second housing guide surface (976) to guide the second pin housing (970) to be inserted into the second space (934). The second housing guide surface (976) can contact the first side wall (931) or the first housing guide surface (933) to guide the second pin housing (970) to be inserted into the second space (934). The first side wall (931) can be inserted into a third space (984) between the second side wall (971) and the third side wall (981). The third housing guide surface (983) can be in contact with the first side wall (931) to guide the first side wall (931) to the third space (984).

The inner surface of the first pin housing (930) may be formed to be inclined so that the opening of the second space (934) gradually narrows in the insertion direction of the second pin housing (970). The inner surface of the first side wall (931) surrounding the side of the second space (934) may gradually narrow in the insertion direction of the second pin housing (970). The inner surface of the first side wall (931) may have a tapered shape. The insertion direction of the second pin housing (970) may be the same as the insertion direction of the first pin (920). The width (w11) of the upper end of the inner surface of the first side wall (931) may be larger than the width (w12) of the lower end.

The outer surface of the second pin housing (970) may be formed to be inclined so as to gradually expand in the insertion direction of the second pin housing (970). The outer surface of the second side wall (971) may gradually expand in the insertion direction of the second pin housing (970). The outer surface of the second side wall (971) may have a tapered shape. The outer surface of the second side wall (971) may have a shape corresponding to the inner surface of the first side wall (931). The width (w21) of the upper end of the outer surface of the second side wall (971) may be smaller than the width (w22) of the lower end.

Accordingly, when the second pin housing (970) is inserted into the second space (934) of the first pin housing (930), the first side wall (931) and the second side wall (971) can slide stably against each other to guide the teeth.

When the upper end of the second pin housing (970) is inserted into the second space (934), the first pin (920) and the second pin (960) can be arranged parallel to each other. When the upper end of the second pin housing (970) is inserted into the second space (934), the inner surface of the first pin housing (930) and the outer surface of the second pin housing (970) can be in contact with each other to arrange the first pin (920) and the second pin (960) parallel to each other.

In a state where the first pin (920) and the second pin (960) are not arranged in parallel, the inner surface of the first pin housing (930) and the outer surface of the second pin housing (970) can secure a specific separation distance by spacing the first pin (920) and the second pin (960) apart from each other. The end of the first pin housing (930) can protrude further than the first pin (920). The end of the second pin housing (970) can protrude further than the second pin (960). For example, the end of the first pin (920) and the end of the first pin housing (930) can be spaced apart from each other by a certain distance (A) in the insertion direction of the first pin (920).

Accordingly, even if the first pin housing (930) and the second pin housing (970) come into contact at an angle relative to the insertion direction of the second pin housing (970), if the upper end of the second pin housing (970) is inserted into the second space (934), the first pin housing (930) and the second pin housing (970) can be arranged parallel to each other. In addition, even if the first pin (920) and the second pin (960) approach each other in an angle relative to the insertion direction of the first pin (920), if the upper end of the second pin housing (970) is inserted into the second space (934), the first pin (920) and the second pin (960) can be arranged parallel to each other before the first pin (920) is inserted into the first space (964) of the second pin (960).

Accordingly, when the first pin (920) is inserted into the first space (964), the first pin (920) and the second pin (960) collide with each other, thereby minimizing damage to the first pin (920) and the second pin (960).

Referring to FIGS. 20 and 21, the display device (1) may include a base (20), a pole (30), and a motion module (MM).

An articulated connector (40) can be coupled to the rear side of the head (10), an elevating module (60) can be coupled to the pole (30), and an arm (50) can connect the articulated connector (40) and the elevating module (60).

Accordingly, the head (10) can be supported by the motion module (MM), the pole (30), and the base (20) and can be spaced upward from the ground.

Meanwhile, the motion module (MM), the pole (30), and the base (20) may be collectively referred to as a stand. Alternatively, the pole (30) and the base (20) may be collectively referred to as a stand.

The fixing portion (24) can be formed by pressing upward from the lower surface of the lower body (20a) and can penetrate the flat weight (81). The battery (Bt, see FIG. 20) can be accommodated inside the fixing portion (24). The substrate (BC) can be mounted on the flat weight (81).

The first connector (910) may be positioned on the flat weight (81). The coupling portion (81P) may protrude upward from the upper surface of the flat weight (81) and may be positioned around the first connector (910).

A light-emitting element (IDL, see FIG. 24) of the indicator (ID) can be formed on the upper body (20b) and can display the remaining amount of the battery (Bt) to the user.

The power cable can be electrically connected to a jack (910i) formed on the other side of the first connector (910). The jack (910i) may be referred to as a port or connector.

For example, the power cable may be connected to the jack (910i). An external power source may be provided to a battery (Bt, see FIG. 1) through the power cable, the first connector (910), the first cable (C10), the first terminal (T11), the substrate (BC), the second terminal (T12), and the second cable (C11), thereby charging the battery (Bt). That is, the battery (Bt) may be a rechargeable battery. The first and second cables (C10, C11) may be referred to as stand-side cables (C10, C11).

For example, the power cable may be separated from the jack (910i).

The first guide rib (21r) may be formed on the inner side of the port (21). The second guide rib (82r) may be formed on the side wall of the raised portion (82a) surrounding the first connector (910). For example, the second guide rib (82r) may be defined by grooves formed by cutting out a portion of the side wall of the raised portion (82a). In the vertical direction, the second guide rib (82r) may be aligned with the first guide rib (21r).

The outer diameter of the insertion portion (31) may be smaller than the outer diameter of the pole (30) (see tz of FIG. 30) and may be substantially the same as the inner diameter of the port (21). The guide slit (31s) may be formed on the side of the insertion portion (31).

The rear grab (45c1) may face the washer (43Fw) with respect to the mount (43F) and may have a circular hole (45ch) through which the body (44b) of the pivot shaft (44) passes. The rear grab (45c1) may be fixed to the rear of the mount (43F).

And, a plurality of fixed holes (45ca) and a plurality of slots (45cb) can be formed in the rear grab (45c1) and can be spaced apart from each other in the circumferential direction of the rear grab (45c1). The plurality of fixed holes (45ca) and the plurality of slots (45cb) can be alternately positioned in the circumferential direction of the rear grab (45c1). For example, the fixed holes (45ca) or the slots (45cb) can be spaced apart from each other at 90 degree intervals. In the circumferential direction of the rear grab (45c1), the length of the slot (45cb) can be greater than the length of the fixed hole (45ca).

The disk (45c2) may be positioned at the rear of the rear grab (45c1), and may have a hole (45c2h) having the same shape as a cross-section of the body (44b) and through which the body (44b) passes. A plurality of bosses (45cc) may protrude from the front of the disk (45c2) toward the rear grab (45c1) and may be spaced apart from each other in the circumferential direction of the disk (45c2). For example, the bosses (45cc) may be spaced apart from each other at 90-degree intervals. The size of the boss (45cc) may be the same as or corresponding to the size of the fixing hole (45ca). That is, when the boss (45cc) is inserted into the fixing hole (45ca), the rotation of the disk (45c2) and the pivot shaft (44) may be limited to a certain level by the rear grab (45c1). Additionally, when the boss (45cc) is inserted into the slot (45cb), the disk (45c2) and the pivot shaft (44) can rotate within the trajectory of the slot (45cb).

Accordingly, the pivot shaft (44) can rotate together with the front bracket (42), the front grab (45a), the disc (45c2), and the cap (45c5). In addition, the pivot shaft (45) can rotate independently of the washer (43Fw), the rear bracket (43), the rear grab (45c1), the washer (45c3), and the disc spring (45c4). In other words, even if the pivot shaft (45) rotates, the washer (43Fw), the rear bracket (43), the rear grab (45c1), the washer (45c3), and the disc spring (45c4) may not rotate.

In addition, the user can pivot the head (10, see FIG. 31) fixed to the front bracket (42) about the pivot shaft (44). For example, the head (10) can pivot within a range of +90 degrees to -90 degrees. In addition, due to the elasticity of the above-described disk springs (45c41, 45c2), the head (10) can maintain a certain pivot angle unless an external force exceeding a certain level is applied. In addition, during the pivot movement of the head (10), the user can feel a feeling of engagement due to the engagement of the boss (45cc) and the fixing hole (45ca) or the slot (45cb). That is, when the boss (45cc) comes out of the slot (45cb) and is inserted into the fixing hole (45ca), the user can feel that the head (10) is positioned at a pivot angle of 0 degrees, +90 degrees, or -90 degrees.

A portion (not shown) of the second lower bushing (68f) can be inserted into the hole (680h) of the second body (680) and can be located between the inner surface of the second body (680) and the outer surface of the second fastening member (68a).

The second upper bushing (68g) can face the second lower bushing (68f) and be spaced upward from the second lower bushing (68f). The second fastening member (68a) can penetrate the second upper bushing (68g). The second upper bushing (68g) can have a cylindrical shape having a flange (not shown) formed at an upper end. The flange of the second upper bushing (68g) can contact a second upper groove (680b) formed along a periphery of a hole (680h) on an upper surface of the second body (680). A portion (not shown) of the second upper bushing (68g) can be inserted into the hole (680h) of the second body (680) and can be located between an inner surface of the second body (680) and an outer surface of the second fastening member (68a).

The second upper washer (68h) can be positioned above the second upper bushing (68g) and can be penetrated by the second fastening member (68a).

The second upper fixing washer (68c) may be opposed to the second upper bushing (68g) with respect to the second upper washer (68h) and may be penetrated by the second fastening member (68a). The second upper fixing washer (68c) may be a toothed lock washer, and the tooth (68ct, tooth) of the second upper fixing washer (68c) may be inserted into and fixed in a groove (not shown) formed on the inner side of the upper arm body (51).

Accordingly, the second body (680) can rotate with respect to the second fastening member (68a). That is, the second fastening member (68a) can provide a second swivel axis. In addition, due to the elasticity of the second disk spring (68d) described above, the head (10) can maintain a certain swivel angle unless an external force exceeding a certain level is applied.

Referring to FIG. 44, the stem (63s) can extend vertically and be aligned with the vertical member (61). The lower end of the stem (63s) can be inserted into the port (21) of the base (20).

The gas spring (62, 63) may include an upper shaft (62) and a lower shaft (63) connected to the upper shaft (62). The upper shaft (62) may extend in the longitudinal direction of the vertical member (61). The upper shaft (62) may have a cylindrical shape with the upper and lower sides closed. At least a portion of the upper shaft (62) may be accommodated inside the vertical member (61). The lower shaft (63) may extend in the longitudinal direction of the upper shaft (62) and may have a diameter smaller than that of the upper shaft (62). The lower shaft (63) may be inserted into the inside of the upper shaft (62). The lower end of the lower shaft (63) may be fixed on a fixing member (69B) fixed on a stem (63s).

These gas springs (62, 63) may have a conventional gas spring structure in which compressed gas (e.g., compressed nitrogen) is filled therein. The upper shaft (62) may be a cylinder in which compressed gas is filled therein. The lower shaft (63) may be a piston rod that may penetrate the lower surface of the upper shaft (62) and have a piston fixed at an end thereof. The piston may be located inside the upper shaft (62) and may partition the internal space of the upper shaft (62) into two spaces. The two spaces may be communicated with each other through an orifice formed in the piston. The area of one surface of the piston connected to the lower shaft (63) may be smaller than the area of the other surface of the piston opposite to the one surface. Accordingly, the overall length of the gas spring (62, 63) may be adjusted by controlling the flow of gas passing through the orifice. The gas spring (62, 63) can be referred to as a gas cylinder.

The clamp (64, 65, clamp) may face the vertical member (61) with respect to the upper shaft (62). In other words, the upper shaft (62) may be positioned between the vertical member (61) and the clamp (64, 65). For example, the clamp (64, 65) may include a plurality of clamps (64, 65) that are spaced apart from each other in the vertical direction.

The clamp (64, 65) may include a semi-cylinder (640, 650), a left flange (641, 651), and a right flange (642, 652). The semi-cylinder (640, 650) may contact the outer periphery of the upper shaft (62). The left flange (641, 651) may extend to the left from one side of the semi-cylinder (640, 650) and may be coupled to a first part (61s1, 65s1) of the vertical member (61) via a fastening member (64F, 65F). The right flange (642, 652) may extend to the right from the other side of the semi-cylinder (640, 650) and may be coupled to a second part (not shown) of the vertical member (61) via a fastening member (not shown).

Accordingly, the upper shaft (62) can be detachably connected to the vertical member (61) and moved up or down along the lower shaft (63).

Referring to FIGS. 44 and 45, rollers (66a, 66b, 67a, 67b) may be adjacent to clamps (64, 65). For example, a first roller (66a, 66b) may be adjacent to a first clamp (64), and a second roller (67a, 67b) may be adjacent to a second clamp (65).

The first roller (66a, 66b) may include a first left roller (66a) and a first right roller (66b). A body (66a1a) of the first left pin (66a1) may penetrate the first left roller (66a) and the left portion (61L) of the vertical member (61). A flange (66a1b) of the first left pin (66a1) may be located between the first left roller (66a) and the left portion (61L). The first left roller (66a) may be coupled to the left portion (61L) through the first left pin (66a1). A body (66b1a) of the first right pin (66b1) may penetrate the first right roller (66b) and the right portion (61R) of the vertical member (61). The flange (66b1b) of the first right pin (66b1) can be positioned between the first right roller (66b) and the right portion (61R). The first right roller (66b) can be coupled to the right portion (61R) via the first right pin (66b1).

For example, the second roller (67a, 67b) may have the same shape as the first roller (66a, 66b). That is, the above-described description of the first roller (66a, 66b) may be equally applied to the second roller (67a, 67b). Accordingly, the second left roller (67a) may be coupled to the left portion (61L), and the second right roller (67b) may be coupled to the right portion (61R).

In addition, the left roller (66a, 67a) can be positioned between the third rib (30c) and the fourth rib (30d) and can contact the third rib (30c) and the fourth rib (30d). The right roller (66b, 67b) can be positioned between the first rib (30a) and the second rib (30b) and can contact the first rib (30a) and the second rib (30b).

Accordingly, the vertical member (61) can smoothly rise or fall inside the pole (30) by the rollers (66a, 66b, 67a, 67b).

Referring to FIGS. 44 and 46, the first left flange (641) of the first clamp (64) may be positioned between the third rib (30c) and the fourth rib (30d). The first right flange (642) of the first clamp (64) may be positioned between the first rib (30a) and the second rib (30b). The first clamp (64) may include a first center protrusion (64a), a first left protrusion (64b), and a first right protrusion (64c).

The first center protrusion (64a) can protrude toward the inside of the pole (30) from the first semi-cylinder (650) and can contact the inside of the pole (30). The first left protrusion (64b) can protrude toward the third rib (30c) from the first left flange (641) and can contact the third rib (30c). The first right protrusion (64c) can protrude toward the second rib (30b) from the first right flange (642) and can contact the second rib (30b). Accordingly, the first center protrusion (64a), the first left protrusion (64b), and the first right protrusion (64c) can cause friction between the vertical member (61) and the pole (30).

For example, the second clamp (65) may be spaced downward from the first clamp (64) and may have the same shape as the first clamp (64). That is, the above-described description of the first clamp (64) may be equally applied to the second clamp (65). Accordingly, the second center protrusion (65a), the second left protrusion (65b), and the second right protrusion (65c) of the second clamp (65) may cause friction between the vertical member (61) and the pole (30).

Accordingly, the position (height) of the vertical member (61) with respect to the base (20) can be maintained constant by the frictional force between the protrusions (64a, 64b, 64c, 65a, 65b, 65c) and the pole (30) unless an external force exceeding a certain level is applied.

Referring to FIG. 47, the head (10) can be spaced upward from the base (20). The user can pivot the head (10). The pivot axis can pass through the center of the head (10) and be orthogonal to the head (10). Referring to the left picture of FIG. 47, the head (10) can be placed in a landscape mode. Referring to the right picture of FIG. 47, the head (10) can be placed in a portrait mode.

Referring to FIG. 48, a user can tilt the head (10). The tilt axis can be a horizontal axis located behind the center of the head (10) and parallel to the head (10). The user can swivel the head (10). A first swivel axis can be a vertical axis adjacent to one end of the arm (50). A second swivel axis can be a vertical axis adjacent to the other end of the arm (50). The user can raise or lower the head (10) from the pole (30).

The pivot, tilt, swivel, and elevating operations of the head (10) described above can be implemented independently of each other. For example, the head (10) can pivot within a range of +90 degrees to -90 degrees. For example, the head (10) can tilt within a range of +25 degrees to -25 degrees. For example, the head (10) can swivel within a range of +65 degrees to -65 degrees. For example, the head (10) can be positioned at 1,065 to 1,265 mm from the base (20) or the ground in landscape mode.

Referring again to FIG. 25, the wheel (29) may be mounted on the lower surface of the base (20). For example, a plurality of wheels (29) may be arranged along the perimeter of the base (20). Accordingly, the user may freely move the display device on the ground using the wheels (29). The base (20) may be referred to as a moving base.
