[0040] Reference Figure 1 and Figure 2 The display device 1 may include a base 20, a pole 30, and a motion module MM.

[0041] The base 20 may be in the shape of a flat cylinder. The base 20 may be placed on the ground. For example, a plurality of moving wheels 20w may be installed on the bottom surface of the base 20 (see FIG. Figure 34 , moving wheels). Thus, the user can move the base 20 smoothly on the ground. The base 20 can be called a mobile base.

[0042] The rod 30 may extend vertically. The lower end of the rod 30 may be coupled to the base 20. The rod 30 may be adjacent to the periphery of the top surface of the base 20. The handle 39 may be coupled to the upper end of the rod 30. The rod 30 and the aforementioned base 20 may be collectively referred to as a bracket.

[0043] The motion module MM may extend in a direction intersecting the rod 30. One side of the motion module MM may be coupled to the rear side of the head 10. The other side of the motion module MM may be adjacent to the upper end of the rod 30 and coupled to the rod 30. An articulated connector (40) may be coupled to the rear side of the head 10, an elevating module 60 may be coupled to the rod 30, and an arm 50 may connect the articulated connector 40 and the elevating module 60.

[0044] Thus, the head 10 may be supported by the motion module MM, the rod 30, and the base 20, and may be spaced apart from the ground toward the upper side.

[0045] Reference Figure 3 and Figure 4 The head 10 may include a display panel 11 , a middle box 12 , a frame 13 , end frames 14 and a back cover 15 .

[0046] The display panel 11 may form the front face of the head 10. For example, the display panel 11 may be an OLED panel, an LCD panel, or an LED panel. The display panel 11 may divide an image into a plurality of pixels and output an image matching the color, brightness, and saturation of each pixel. The display panel 11 may be divided into an active area for displaying an image and a de-active area for not displaying an image. The display panel 11 may generate light corresponding to red, green, or blue according to a control signal.

[0047] The middle housing 12 may extend along the periphery of the display panel 11. The horizontal portion 12H may be located in front of the display panel 11. The vertical portion 12V may intersect the horizontal portion 12H and cover the side of the display panel 11. The front pad 11F may be located between the horizontal portion 12H and the display panel 11 and coupled to the horizontal portion 12H. The rear pad 11R may be opposite to the front pad 11F across the display panel 11. For example, the middle housing 12 may include a metal or plastic material. The middle housing 12 may be referred to as a side frame or a guide panel.

[0048] The frame 13 may be located behind the display panel 11. Electronic components such as a printed circuit board (PCB) may be incorporated into the back of the frame 13. For example, the frame 13 may be made of metal. The frame 13 may be referred to as a board or a module cover.

[0049] The fixing portions 13H may protrude rearward from the back of the frame 13. The fixing portions 13H may be pemnuts. The intervals between the fixing portions 13H may comply with VESA (Video Electronics Standards Association) standards.

[0050] The end frames 14 may form the outer periphery of the head portion 10. The horizontal portion 14H may be located in front of the horizontal portion 12H of the middle housing 12. The vertical portion 14V may cover the sides of the vertical portion 12V of the middle housing 12. For example, the end frames 14 may be made of metal or plastic. Alternatively, depending on the embodiment, the end frames 14 may be omitted, in which case the middle housing 12 may form the outer periphery of the head portion 10.

[0051] The back cover 15 forms the back of the head 10. The back cover 15 can be located behind the frame 13 and coupled to the frame 13. A portion of the frame 13, including the aforementioned fixing portion 13H, can be exposed to the outside through a hole 15h formed in the center of the back cover 15. For example, the back cover 15 can be made of metal or plastic. For example, a jersey fabric can be detachably coupled to the back of the back cover 15.

[0052] Reference Figure 4 and Figure 5 , the fixing member 41 may be located in the hole 15 h of the rear cover 15 and behind the frame 13 .

[0053] The fixing plate 41a can be generally circular in shape and have fixing holes 41H aligned with the fixing portion 13H. The spacing between the fixing holes 41H can comply with the VESA standard. The fixing ring 41b can be located between the outer periphery of the fixing plate 41a and the portion defining the hole 15h of the rear cover 15 and can be coupled or fixed thereto. A fastening member such as a bolt can be fastened to the fixing portion 13H through the fixing holes 41H. Thus, the fixing member 41 can be coupled or fixed to the frame 13.

[0054] Reference Figure 5 and Figure 6 , the articulated connector 40 may have the aforementioned fixing member 41. The front bracket 42 may be located behind the fixing member 41 and may be plate-shaped as a whole. A pair of first protrusions 42a may protrude upward from the upper side of the front bracket 42 and be spaced apart from each other in the left-right direction. A pair of second protrusions 42b may protrude downward from the lower side of the front bracket 42 and be spaced apart from each other in the left-right direction. The pair of first protrusions 42a and the pair of second protrusions 42b may be inserted and coupled to holes (not shown) formed in the fixing plate 41a. Thus, the front bracket 42 may be detachably coupled to the fixing plate 41a (refer to Figure 11 ).

[0055] The pivot shaft 44 can extend in the front-to-back direction. The diameter of the head 44a of the pivot shaft 44 can be larger than the diameter of the main body 44b. The main body 44b can be in the shape of a cylinder with a portion of the side cut out. A pair of cutouts 44c can be formed on the side of the main body 44b and opposite to each other. The hole 42h of the front bracket 42 can be formed in the center portion of the front bracket 42 and can be penetrated by the main body 44b. The shape of the hole 42h of the front bracket 42 can be the same as the longitudinal cross-sectional shape of the main body 44b. Thus, the pivot shaft 44 and the front bracket 42 can rotate together relative to the axial direction of the pivot shaft 44. That is, the pivot shaft 44 can provide a pivot.

[0056] Front claw 45a (front grab) can be located between head 44a and the front face of front bracket 42. Hole 45ah of front claw 45a can be aligned with hole 42h of front bracket 42 and can have the same shape as hole 42h. Body 44b can extend through holes 45ah and 42h. Protrusions 45af can protrude rearward from the periphery of front claw 45a, can be spaced apart at 90-degree intervals, and can be inserted into slots or holes 42f coupled to front bracket 42. Thus, front claw 45a can further securely couple pivot shaft 44 and front bracket 42.

[0057] Reference Figure 7 and Figure 8 The rear bracket 43 may be located behind the front bracket 42. The rear bracket 43 may include a mounting portion 43F, a left wing 43L (left wing) and a right wing 43R (right wing).

[0058] Mounting portion 43F may face front bracket 42 and have a circular mounting hole 43Fh. Main body 44b of pivot shaft 44 may extend through mounting hole 43Fh and rotate independently of mounting portion 43F within mounting hole 43Fh. In other words, even if pivot shaft 44 rotates, rear bracket 43 may not rotate. For example, at least one washer 43Fw may be positioned between front bracket 42 and mounting portion 43F, and may have a circular hole through which main body 44b extends.

[0059] Left wing 43L can extend rearward from the left side of mounting portion 43F. Right wing 43R can extend rearward from the right side of mounting portion 43F. Multiple components 45c (45c1, 45c2, 45c3, 45c4, and 45c5) described below can be coupled to mounting portion 43F between left wing 43L and right wing 43R.

[0060] A rear grab 45c1 (rear grab) may face the washer 43Fw across the mounting portion 43F and may have a circular hole 45ch through which the main body 44b of the pivot shaft 44 passes. Protrusions 45cf may protrude forward from the periphery of the rear grab 45c1, may be spaced 90 degrees apart, and may be inserted into and engaged with the slots or holes 42Ff of the mounting portion 43F. This allows the rear grab 45c1 to engage with the back surface of the mounting portion 43F.

[0061] Furthermore, a plurality of fixing holes 45ca and a plurality of slots 45cb can be formed through the rear grip 45c1 along its thickness direction and can be spaced apart from one another in the circumferential direction of the rear grip 45c1. The plurality of fixing holes 45ca and the plurality of slots 45cb can be alternately positioned in the circumferential direction of the rear grip 45c1. For example, the fixing holes 45ca or the slots 45cb can be spaced apart at 90-degree intervals. The length of the slots 45cb can be greater than the length of the fixing holes 45ca in the circumferential direction of the rear grip 45c1.

[0062] Disc 45c2 (disc) can be located behind rear grip 45c1 and can have a hole 45c2h through which the main body 44b of pivot shaft 44 passes. The shape of hole 45c2h can be the same as the shape of the longitudinal cross-section of main body 44b. Multiple protrusions 45cc (bosses) can protrude from the front of disc 45c2 toward rear grip 45c1 and be spaced apart from each other in the circumferential direction of disc 45c2. For example, the protrusions 45cc can be spaced apart at 90-degree intervals. The size of the protrusions 45cc can be the same as or correspond to the size of the fixing hole 45ca. That is, when the protrusions 45cc are inserted into the fixing hole 45ca, the rotation of disc 45c2 and pivot shaft 44 can be limited by rear grip 45c1. In addition, when the protrusions 45cc are inserted into the narrow slot 45cb, disc 45c2 and pivot shaft 44 can rotate within the trajectory of the narrow slot 45cb.

[0063] The washer 45c3 may be located behind the disk 45c2 and may have a circular hole (not numbered) through which the main body 44b of the pivot shaft 44 passes.

[0064] The disc spring 45c4 (disc spring) can be opposite to the disc 45c2 via the washer 45c3, and can have a circular hole (not marked) for the main body 44b of the pivot shaft 44 to pass through. The disc spring 45c4 can be elastic and can protrude forward or backward. The disc spring 45c4 can generate an elastic force in the axial direction of the pivot shaft 44. For example, there can be a pair of disc springs 45c4. In this case, the first disc spring 45c41 and the second disc spring 45c42 can protrude in different directions from each other. The first disc spring 45c41 can protrude backward, and the second disc spring 45c42 can protrude forward behind the first disc spring 45c41. Thereby, the overall elastic force of the first disc spring 45c41 and the second disc spring 45c42 can be strengthened.

[0065] Cap 45c5 (cap) can be located behind disc spring 45c4 and has a hole 45c5h through which body 44b of pivot shaft 44 passes. The shape of hole 45c5h can be the same as the longitudinal cross-section of body 44b. Cap 45c5 can be coupled or fixed to the end of body 44b.

[0066] Thus, pivot shaft 44 can rotate along with front bracket 42, front claw 45a, disc 45c2, and cap 45c5. Furthermore, pivot shaft 45 can rotate independently of washer 43Fw, rear bracket 43, rear claw 45c1, washer 45c3, and disc spring 45c4. In other words, even if pivot shaft 45 rotates, washer 43Fw, rear bracket 43, rear claw 45c1, washer 45c3, and disc spring 45c4 do not rotate.

[0067] In addition, the user can make the head 10 (refer to Figure 5 ) pivots relative to pivot shaft 44. For example, head 10 can pivot within a range of +90 degrees to -90 degrees. Furthermore, the elastic force of disc springs 45c41 and 45c2 allows head 10 to maintain a predetermined pivot angle as long as no external force exceeding a predetermined level is applied. Furthermore, during the pivoting motion of head 10, the user can feel a sense of tightness derived from the fastening of protrusion 45cc to fixing hole 45ca or slot 45cb. Specifically, when protrusion 45cc leaves slot 45cb and enters fixing hole 45ca, the user can sense that head 10 is at a pivot angle of 0 degrees, +90 degrees, or -90 degrees.

[0068] On the other hand, the left protrusion 42L can be located between the center and the left side of the front bracket 42 and can protrude rearward from the front bracket 42. The right protrusion 42R can be located between the center and the right side of the front bracket 42 and can protrude rearward from the front bracket 42. Furthermore, a stopper 43S can protrude upward from the upper edge of the mounting portion 43F and be located in the rotational path of the left protrusion 42L and the right protrusion 42R. Thus, the stopper 43S can limit the rotation of the front bracket 42 and the pivot shaft 44 to a predetermined angle.

[0069] Reference Figure 9 , the retainer 47 can be located between the left wing 43L and the right wing 43R. The retainer body 470 can cover the rear of the mounting portion 43F of the rear bracket 43. The first portion 47L can protrude from the left side of the retainer body 470 toward the mounting portion 43F and be adjacent to the left wing 43L. The second portion 47R (refer to Figure 7 ) can protrude from the right side of the retainer toward the mounting portion 43F and be adjacent to the right side wing 43R.

[0070] A tilt shaft 46 may extend in the left-right direction. The tilt shaft 46 may penetrate the left wing 43L, the first portion 47L, the second portion 47R, and the right wing 43R. A head (not labeled) at one end of the tilt shaft 46 may be positioned on a side surface of the left wing 43L. The other end of the tilt shaft 46 may be threaded, and a fastening member 46d, such as a nut, may be fastened to the other end of the tilt shaft 46 on the right wing 43R.

[0071] Furthermore, the tilt shaft 46 can be generally cylindrical and fixed to the left wing 43L and the right wing 43R. The tilt shaft 46 can be rotatably coupled to the holder 47. In other words, the tilt shaft 46 can provide a tilt axis. At least one washer 46v can be positioned between the second portion 47R and the right wing 43R and have a circular hole through which the tilt shaft 46 passes.

[0072] The elastic member 46b may be located between the left wing 43L and the right wing 43R. The elastic member 46b may be wound around the outer circumference of the tilt shaft 46 a plurality of times and have elasticity. The elastic member 46b may be a coil-shaped spring.

[0073] Furthermore, a portion 46b of the elastic member 46a may extend in a direction intersecting the tilt shaft 46 without being wrapped around the tilt shaft 46. A seating portion 43h may protrude rearward from the lower edge of the mounting portion 43F of the rear bracket 43 and may be adjacent to the left wing 43L. The seating portion 43h may have a groove into which a portion of the elastic member 46a is inserted. In other words, a portion of the elastic member 46a may be retained in the groove of the seating portion 43h.

[0074] In addition, one end of the elastic member 46a may be formed in the portion 46b. A disc spring 46w may be adjacent to the other end 46c of the elastic member 46a and located between the elastic member 46a and the second portion 47R. The disc spring 46w may have a circular hole (not shown) through which the tilt shaft 46 passes. The disc spring 46w may be elastic and protrude toward the elastic member 46a. The disc spring 46w may generate an elastic force in the axial direction of the tilt shaft 46. A washer 46u may be located between the disc spring 46w and the second portion 47R and have a circular hole through which the tilt shaft 46 passes.

[0075] Thus, the tilt shaft 46 can rotate together with the rear bracket 43, the front bracket 42 and the plurality of components 45c5, 45c4, 45c3, 45c2, 45c1, 43Fw, 45a, and 44. The head 10 (see FIG. 1 ) fixed to the front bracket 42 Figure 5) can be tilted up and down in response to the rotation of the tilt shaft 46. In this case, the elastic member 46a can provide a force to support the head 10 tilted at a predetermined angle. In addition, the disc spring 46w can also provide a force to maintain the angle of the head 10 tilted at a predetermined angle unless an external force exceeding a predetermined level is applied.

[0076] For example, the head 10 can be tilted within a range of +25 to -25 degrees. In addition, due to the elastic force of the elastic member 46a and the disc spring 46w, the head 10 can maintain a predetermined tilt angle unless an external force exceeding a predetermined level is applied.

[0077] On the other hand, a pin 47P (pin) may be fixed to the first portion 47L and / or the second portion 47R. For example, the pin 47P may protrude to the left from the side of the first portion 47L.

[0078] At this time, the guide groove 43g may be formed as it is recessed forward from the rear end of the left wing 43L. The reference point 43ga may be formed on the head 10 (refer to Figure 5 ) contacts the pin 47P in a state where it is not tilted upward or downward. The rising groove 43gb can be formed in an arc shape along the first rotation direction from the reference point 43ga. The descending groove 43gc can be formed in an arc shape along the second rotation direction opposite to the first rotation direction from the reference point 43ga.

[0079] Here, the tilt shaft 46 can rotate in either the first or second rotational direction. When the tilt shaft 46 rotates in the first rotational direction, the pin 47P can move relative to the descending groove 43gc. The rotation of the tilt shaft 46 can be limited by the engagement between the descending groove 43gc and the pin 47P. When the tilt shaft 46 rotates in the second rotational direction, the pin 47P can move relative to the ascending groove 43gb. The rotation of the tilt shaft 46 can be limited by the engagement between the ascending groove 43gb and the pin 47P.

[0080] Thus, the maximum angle at which the head portion 10 can be tilted upward can be determined by the length of the ascending groove 43gb. Furthermore, the maximum angle at which the head portion 10 can be tilted downward can be determined by the length of the descending groove 43gc. For example, the head portion 10 can be tilted within a range of +25 degrees to -25 degrees.

[0081] Reference Figure 10 , the first rotating unit 48 may be located behind the holder. The first connecting portion 471 may connect the holder and the first rotating unit 48. For example, the holder, the first connecting portion 471, and the first rotating unit 48 may be formed as one body.

[0082] The cable holder 49 can be located behind the front bracket 42 and can be penetrated by the rear bracket 43 and the holder. The cable holder 49 can be coupled to the left and right wings 43L and 43R via fastening members such as bolts. The first plate 49a and the second plate 49b can be generally annular and spaced apart from each other in the front-to-back direction. Thus, a cable (not shown) can be wound around the cable holder 49 between the first and second plates 49a, 49b.

[0083] Reference Figure 11 and 12 As mentioned above, the front bracket 42 can be detachably connected to the fixing plate 41a (refer to Figure 5 ).

The fastening members 49f1, 49f2 may protrude rearward through the cable holder 49 and be coupled to the inner side of the cover 40c1. For example, the fastening members 49f1, 49f2 may be screws or bolts.

[0085] Reference Figure 13 and Figure 14 The arm 50 may include arm bodies 51 and 52. The arm bodies 51 and 52 may extend in a direction inclined upward at a predetermined angle (acute angle) relative to the horizontal plane. The arm bodies 51 and 52 may also extend parallel to the horizontal plane. For example, the upper arm body 51 and the lower arm body 52 may be coupled to each other in a vertical direction. As another example, the upper arm body 51 and the lower arm body 52 may be formed as one body. The arm 50 may be referred to as a rod 50 or a link 50.

[0086] The front portion of the upper arm body 51 can be separated upward from the front portion of the lower arm body 52. A front groove 50g1 can be formed in the front portion of each arm body 51, 52, and has a "U" shape that opens forward. The rear portion of the upper arm body 51 can be separated upward from the rear portion of the lower arm body 52. A rear groove 50g2 can be formed in the rear portion of each arm body 51, 52, and has a "U" shape that opens backward.

[0087] The upper insertion hole 51a may be formed vertically through the front portion of the upper arm body 51 and may face the front groove 50g1. The upper fastening hole 51b may be formed vertically through the rear portion of the upper arm body 51 and may face the rear groove 50g2.

[0088] The lower fastening hole 52a may be formed vertically through the front portion of the lower arm body 52 and aligned with the upper insertion hole 51a. The lower insertion hole 52b may be formed vertically through the rear portion of the lower arm body 52 and aligned with the upper fastening hole 51b.

[0089] On the other hand, the cable groove 50c may be formed on the bottom surface of the lower arm body 52 and extend along the length direction of the lower arm body 52. Figure 19 ) can be located in the cable trough 50c.

[0090] Alternatively, a portion of the top surface of the upper arm body 51 may be recessed. In this case, a plurality of ribs 51r may be formed on the portion of the top surface of the upper arm body 51. This reduces the weight of the arm bodies 51 and 52 while ensuring their rigidity.

[0091] Reference Figure 15 The cover ring 40c2 may extend along the periphery of the cover 40c1 and may be detachably coupled to the fixing ring 41b (see Figure 11 ).

[0092] The upper cover 53 can cover the upper arm body 51 (see Figure 14 ) surface. The lower cover 54 can cover the lower arm body 52 (refer to Figure 14 The upper cover 53 and the lower cover 54 may be formed separately or may be formed in one body.

[0093] The first rotating unit 48 can be inserted into the front groove 50g1 and rotatably coupled to the arm 50. The second rotating unit 68 can be inserted into the rear groove 50g2 and rotatably coupled to the arm 50. On the other hand, the second rotating unit 68 can protrude from the vertical member 61 described later toward the rear groove 50g2.

[0094] Reference Figure 15 and Figure 16 The first rotating unit 48 may include a first body 480, a first fastening member 48a, a first upper fixing washer 48b, a first disc spring 48d, a first upper washer 48e, a first upper bushing 48f, a first lower bushing 48g, a first lower washer 48h, and a first lower fixing washer 48c. The first rotating unit 48 may be referred to as a first rotating module 48.

[0095] The first body 480 may be open at the top and bottom. The first body 480 may be donut-shaped as a whole. For example, the first body 480 may be formed integrally with the first connection portion 471. The first body 480 may be inserted into the front groove 50g1.

[0096] The first fastening member 48a may extend in the vertical direction. The first fastening member 48a may be inserted through the upper insertion hole 51a (refer to Figure 14 ) is inserted into the arm 50 and can pass through the hole 480h formed in the center portion of the first body 480. The head 48ah of the first fastening member 48a can be located inside the upper arm body 51. The first fastening member 48a can be connected to the lower fastening hole 52a (refer to Figure 14 )Threaded connection.

[0097] The first upper fixing washer 48b may be located below the head portion 48ah of the first fastening member 48a and may be penetrated by the first fastening member 48a. The first upper fixing washer 48b may be fixed to the inside of the upper arm body 51. For example, the first upper fixing washer 48b may be a toothed lock washer. The teeth 48bt of the first upper fixing washer 48b may be inserted into and engaged with grooves (not shown) formed on the inside of the upper arm body 51.

[0098] The first disc spring 48d may be located below the first upper fixing washer 48b. The first disc spring 48d may be elastic and may protrude toward the first upper fixing washer 48b. The first disc spring 48d may generate elastic force in the axial direction of the first fastening member 48a.

[0099] The first upper washer 48e may be located at a lower side of the first disc spring 48d and may be penetrated by the first fastening member 48a. The first upper washer 48e may have a ring shape.

[0100] The first upper bushing 48f can be opposite to the first disc spring 48d via the first upper washer 48e. The first fastening member 48a can pass through the first upper bushing 48f. The first upper bushing 48f can be in the shape of a tube with a flange (not marked) formed at the upper end. The flange of the first upper bushing 48f can contact the first upper groove 480a formed around the hole 480h on the top surface of the first main body 480. A portion (not marked) of the first upper bushing 48f can be inserted into the hole 480h of the first main body 480, can be located between the inner circumferential surface of the first main body 480 and the outer circumferential surface of the first fastening member 48a, and can contact the inner circumferential surface of the first main body 480 and the outer circumferential surface of the first fastening member 48a.

[0101] The first lower bushing 48g can be opposite to the first upper bushing 48f and can be separated from the first upper bushing 48f to the lower side. The first fastening member 48a can pass through the first lower bushing 48g. The first lower bushing 48g can be in the shape of a tube with a flange (not marked) formed at the lower end. The flange of the first lower bushing 48g can contact the first lower groove 480b formed around the hole 480h on the bottom surface of the first main body 480. A portion (not marked) of the first lower bushing 48g can be inserted into the hole 480h of the first main body 480, can be located between the inner circumference of the first main body 480 and the outer circumference of the first fastening member 48a, and can contact the inner circumference of the first main body 480 and the outer circumference of the first fastening member 48a.

[0102] The first lower washer 48h may be located at a lower side of the first lower bushing 48g and may be penetrated by the first fastening member 48a. The first lower washer 48h may have a ring shape.

[0103] The first lower fixing washer 48c may be opposite the first lower bushing 48g via the first lower washer 48h and may be penetrated by the first fastening member 48a. The first lower fixing washer 48c may be fixed to the inner side of the lower arm body 52. For example, the first lower fixing washer 48c may be a toothed lock washer. The teeth 48c of the first lower fixing washer 48c may be inserted into and engaged with grooves (not shown) formed on the inner side of the lower arm body 52.

[0104] As a result, the first body 480 can rotate relative to the first fastening member 48a. In other words, the first fastening member 48a provides a first rotation axis. Furthermore, the elastic force of the first disc spring 48d allows the head 10 to maintain a predetermined rotation angle unless an external force exceeding a predetermined level is applied.

[0105] On the other hand, the first groove 48g can be formed on the side of the first body 480 along the circumferential direction of the first body 480. The first groove 48g can be oriented toward the inner side of the front groove 50g1. The first protrusion 511 can protrude from the front groove 50g1 toward the first groove 48g and be inserted into the first groove 48g. The length of the first protrusion 511 can be less than the length of the first groove 48g. That is, when the first body 480 rotates relative to the first fastening member 48a, the first protrusion 511 can move relatively along the first groove 48g. The rotation of the first body 480 can be limited by the engagement of one end or the other end of the first groove 48g with the first protrusion 511.

[0106] Therefore, the maximum angle by which the head 10 can rotate left and right can be determined according to the length of the first groove 48g.

[0107] Reference Figure 15 and Figure 17 The second rotating unit 68 may include a second body 680, a second fastening member 68a, a second lower fixing washer 68b, a second disc spring 68d, a second lower washer 68e, a second lower bushing 68f, a second upper bushing 68g, a second upper washer 68h, and a second upper fixing washer 68c. The second rotating unit 68 may be referred to as a second rotating module 68.

[0108] The second body 680 may be open at the top and bottom. The second body 680 may be donut-shaped overall. The second body 680 may be connected to the vertical member 61 via the second connecting portion 611. For example, the second body 680, the second connecting portion 611, and the vertical member 61 may be formed as one body. The second body 680 may be inserted into the rear groove 50g2.

[0110] The second lower fixing washer 68b may be located above the head portion 68ah of the second fastening member 68a and may be penetrated by the second fastening member 68a. The second lower fixing washer 68b may be fixed to the inside of the lower arm body 52. For example, the second lower fixing washer 68b may be a toothed lock washer. The teeth 68bt of the second lower fixing washer 68b may be inserted into and engaged with grooves (not shown) formed on the inside of the lower arm body 52.

[0111] The second disc spring 68d may be located above the second lower fixing washer 68b. The second disc spring 68d may be elastic and protrude toward the second lower fixing washer 68b. The second disc spring 68d may generate elastic force in the axial direction of the second fastening member 68a.

[0112] The second lower washer 68e may be located on an upper side of the second disc spring 68d and may be penetrated by the second fastening member 68a. The second lower washer 68e may have a ring shape.

[0113] The second lower bushing 68f can be opposite to the second disc spring 68d via the second lower washer 68e. The second fastening member 68a can penetrate the second lower bushing 68f. The second lower bushing 68f can be in the shape of a tube with a flange (not marked) formed at the lower end. The flange of the second lower bushing 68f can contact the second lower groove 680a formed around the hole 680h on the bottom surface of the second body 680. A portion (not marked) of the second lower bushing 68f can be inserted into the hole 680h of the second body 680, can be located between the inner circumference of the second body 680 and the outer circumference of the second fastening member 68a, and can contact the inner circumference of the second body 680 and the outer circumference of the second fastening member 68a.

[0114] The second upper bushing 68g can be opposite to the second lower bushing 68f and separated from the second lower bushing 68f to the upper side. The second fastening member 68a can penetrate the second upper bushing 68g. The second upper bushing 68g can be in the shape of a tube with a flange (not marked) formed at the upper end. The flange of the second upper bushing 68g can contact the second upper groove 680b formed around the hole 680h on the top surface of the second main body 680. A portion (not marked) of the second upper bushing 68g can be inserted into the hole 680h of the second main body 680, can be located between the inner circumference of the second main body 680 and the outer circumference of the second fastening member 68a, and can contact the inner circumference of the second main body 680 and the outer circumference of the second fastening member 68a.

[0115] The second upper washer 68h may be located at an upper side of the second upper bushing 68g and may be penetrated by the second fastening member 68a. The second upper washer 68h may have a ring shape.

[0116] The second upper fixing washer 68c may be opposite the second upper bushing 68g via the second upper washer 68h and may be penetrated by the second fastening member 68a. The second upper fixing washer 68c may be fixed to the inner side of the upper arm body 51. For example, the second upper fixing washer 68c may be a toothed lock washer. The teeth 68ct of the second upper fixing washer 68c may be inserted into and engaged with grooves (not shown) formed on the inner side of the upper arm body 51.

[0117] This allows the second body 680 to rotate relative to the second fastening member 68a. In other words, the second fastening member 68a provides a second rotation axis. Furthermore, the elastic force of the second disc spring 68d allows the head 10 to maintain a predetermined rotation angle unless an external force exceeding a predetermined level is applied.

[0118] On the other hand, the second groove 68g can be formed on the side of the second body 680 along the circumferential direction of the second body 680. The second groove 68g can be oriented toward the inner side of the rear groove 50g2. The second protrusion 512 can protrude from the rear groove 50g2 toward the second groove 68g and be inserted into the second groove 68g. The length of the second protrusion 512 can be less than the length of the second groove 68g. That is, when the second body 680 rotates relative to the second fastening member 68a, the second protrusion 512 can move relatively along the second groove 68g. The rotation of the second body 680 can be limited by the engagement of one end or the other end of the second groove 68g with the second protrusion 512.

[0119] Therefore, the maximum angle by which the head 10 can rotate left and right can be determined according to the length of the second groove 68g.

[0120] Reference Figure 18 The arm 50 may extend in a direction intersecting the head 10 and the rod 30. The arm 50 may connect the articulated connector 40 and the lifting module 60. The second rotation unit 68 and the vertical member 61 of the lifting module 60 may be connected by a second connection portion 611. The second connection portion 611 may pass through the rod 30.

[0121] The vertical member 61 may extend along the length direction of the rod 30. The vertical member 61 may be accommodated inside the rod 30. A partition wall 61w may be adjacent to an upper end of the vertical member 61.

[0122] The rod 30 may extend in the vertical direction and surround the vertical member 61. A plurality of ribs 30a, 30b, 30c, and 30d may be located between the rod 30 and the vertical member 61 and spaced apart from each other in the circumferential direction of the rod 30. The first rib 30a, the second rib 30b, the third rib 30c, and the fourth rib 30d may be located at any vertex of a quadrilateral inside the rod 30.

[0123] Also, the lower end 31 of the rod 30 may be inserted into and coupled to a port 21 formed on the top surface of the base 20. For example, the port 21 may be in the shape of a monticule.

[0124] Reference Figure 19 and Figure 20 The vertical member 61 may be in the shape of a cylinder cut in half as a whole. The rear side and the lower side of the vertical member 61 may be open, and the upper side may be blocked by a partition wall 61w.

[0125] The upper shaft 62 can extend along the length of the vertical member 61. It can be cylindrical with its upper side blocked. At least a portion of the upper shaft 62 can be housed within the vertical member 61. A protrusion 62a can protrude upward from the upper side of the upper shaft 62 and penetrate the partition wall 61w. A fastening member 62b, such as a nut, can be threadedly engaged with the protrusion 62a on the partition wall 61w. This allows the upper shaft 62 to be detachably coupled to the vertical member 61.

[0126] The cap 69T can be clamped on the upper end of the vertical member 61 and can be flat. The mounting seat 69M can be located on the cap 69T and can be fastened to the plurality of ribs 30a, 30b, 30c, 30d (see FIG. 1 ) by vertical fastening members 69F1. Figure 18 The handle body 39a of the handle 39 can be opposite to the cap 69T across the mounting seat 69M and can be fastened to the mounting seat 69M by a horizontal fastening member 69F2. The handle body 39a can be in a track shape as a whole and is covered by the handle cover 39b (see Figure 2 )cover.

[0127] Reference Figure 21 , the valve stem 63s (stem) can extend in the vertical direction and be aligned with the vertical member 61. The lower end of the valve stem 63s can be inserted into the port 21 of the base 20.

[0128] The gas springs 62 and 63 may include the aforementioned upper shaft 62 and a lower shaft 63 connected to the upper shaft 62 from above. The lower shaft 63 may extend along the length of the upper shaft 62 and have a smaller diameter than the upper shaft 62. In other words, the lower shaft 63 may be inserted into the inner side of the upper shaft 62. The lower end of the lower shaft 63 may be fixed to the valve stem 63s.

[0129] Clamps 64 and 65 may be positioned opposite the vertical member 61 across the upper shaft 62. In other words, the upper shaft 62 may be positioned between the vertical member 61 and the clamps 64 and 65. For example, a plurality of clamps 64 and 65 may be provided. For example, the first clamp 64 and the second clamp 65 may be spaced apart from each other in the vertical direction.

[0130] The first clamp 64 may include a first half-cylinder 640, a first left flange 641, and a first right flange 642. The first half-cylinder 640 may contact the outer periphery of the upper shaft 62. The first left flange 641 may extend leftward from one side of the first half-cylinder 640 and may be coupled to the first portion 61s1 of the vertical member 61 via a fastening member 64F. The first right flange 642 may extend rightward from the other side of the first half-cylinder 640 and may be coupled to the second portion 61s2 of the vertical member 61 via a fastening member (not shown).

[0131] The second clamp 65 may include a second half-cylinder 650, a second left flange 651, and a second right flange 652. The second half-cylinder 650 may contact the outer periphery of the upper rotating shaft 62. The second left flange 651 may extend leftward from one side of the second half-cylinder 650 and may be coupled to the third portion 65s1 of the vertical member 61 via a fastening member 65F. The second right flange 652 may extend rightward from the other side of the second half-cylinder 640 and may be coupled to the fourth portion (not shown) of the vertical member 61 via a fastening member (not shown).

[0132] Thus, the upper rotation shaft 62 can be detachably coupled to the vertical member 61. In addition, the upper rotation shaft 62 can move upward or downward along the lower rotation shaft 63.

[0133] Reference Figure 21 and Figure 22 , the rollers 66a, 66b, 67a, 67b can be adjacent to the clamps 64, 65. For example, the first rollers 66a, 66b can be adjacent to the first clamp 64, and the second rollers 67a, 67b can be adjacent to the second clamp 65.

[0134] The first rollers 66a and 66b may include a first left roller 66a and a first right roller 66b. The body 66a1a of the first left pin 66a1 may extend through the first left roller 66a and the left side 61L of the vertical member 61. The flange 66a1b of the first left pin 66a1 may be positioned between the first left roller 66a and the left side 61L. The first left roller 66a may be coupled to the left side 61L via the first left pin 66a1. The body 66b1a of the first right pin 66b1 may extend through the first right roller 66b and the right side 61R of the vertical member 61. The flange 66b1b of the first right pin 66b1 may be positioned between the first right roller 66b and the right side 61R. Thus, the first right roller 66b may be coupled to the right side 61R via the first right pin 66b1.

[0135] For example, the second rollers 67a and 67b can have the same shape as the first rollers 66a and 66b. That is, the same descriptions as those for the first rollers 66a and 66b apply to the second rollers 67a and 67b. Thus, the second left roller 67a can be coupled to the left side portion 61L, and the second right roller 67b can be coupled to the right side portion 61R.

[0136] Furthermore, the left rollers 66a and 67a can be located between the third and fourth ribs 30c and 30d, and can contact the third and fourth ribs 30c and 30d. The right rollers 66b and 67b can be located between the first and second ribs 30a and 30b, and can contact the first and second ribs 30a and 30b. For example, the rollers 66a, 66b, 67a, and 67b can have oil grooves for the flow of a fluid such as oil. For example, the rollers 66a, 66b, 67a, and 67b can be made of POM (Poly Oxy Methylene).

[0137] Thus, the vertical member 61 can smoothly rise or fall inside the rod 30 by the rollers 66a, 66b, 67a, and 67b.

[0138] Reference Figure 21 and Figure 23 The first left flange 641 of the first clamp 64 can be located between the third rib 30c and the fourth rib 30d. The first right flange 642 of the first clamp 64 can be located between the first rib 30a and the second rib 30b. The first clamp 64 can include a first central protrusion 64a, a first left protrusion 64b, and a first right protrusion 64c.

[0139] The first central protrusion 64a can protrude from the first half-tube 650 toward the inner side of the rod 30 and contact the inner side of the rod 30. For example, the plurality of first central protrusions 64a can be spaced apart and parallel to each other. The first left protrusion 64b can protrude from the first left flange 641 toward the third rib 30c and contact the third rib 30c. The first right protrusion 64c can protrude from the first right flange 642 toward the second rib 30b and contact the second rib 30b. Thus, the first central protrusion 64a, the first left protrusion 64b, and the first right protrusion 64c can generate friction between the vertical member 61 and the rod 30.

[0140] For example, the second clamp 65 may be spaced downward from the first clamp 64 and have the same shape as the first clamp 64. That is, the aforementioned contents regarding the first clamp 64 are equally applicable to the second clamp 65. Thus, the second center protrusion 65a, the second left protrusion 65b, and the second right protrusion 65c of the second clamp 65 can generate friction between the vertical member 61 and the rod 30.

[0141] Therefore, unless an external force exceeding a predetermined level is applied, the position (height) of the vertical member 61 relative to the base 20 can be kept constant by the friction between the protrusions 64a, 64b, 64c, 65a, 65b, 65c and the rod 30.

[0142] On the other hand, the lengths of the left protrusions 64b, 65b and the right protrusions 64c, 65c can be smaller than the lengths of the center protrusions 64a, 65a. Thus, the rod 30 can have a plurality of ribs 30a, 30b, 30c, 30d, which can sufficiently ensure the rigidity of the rod 30.

[0143] Refer again Figure 22 and Figure 23 The cable groove 61g can be formed in the front portion 61F of the vertical member 61 and can be formed long in the vertical direction. The cable C can be inserted into the cable groove 61g. This cable C can be inserted along the cable groove 50c of the arm 50 (refer to Figure 14 ) configuration, and can be electrically connected to the head 10. In addition, the cable C can be along the valve stem 63s (refer to Figure 21 ) is configured and electrically connected to the battery Bt (refer to Figure 1 ) and other electronic components.

[0144] Reference Figure 24 , the head 10 can be separated from the base 20 to the upper side. The user can pivot the head 10. At this time, the pivot axis can pass through the center of the head 10 and be orthogonal to the head 10. Figure 24 The left side of the figure shows that the head 10 can be in a horizontal mode. Figure 24 As shown in the right side of the figure, the head 10 may be in a portrait mode.

[0145] Reference Figure 25 , the user can tilt the head 10. At this time, 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 rotate the head 10. At this time, the first rotation axis can be a vertical axis adjacent to one end of the arm 50. Alternatively, the second rotation axis can be a vertical axis adjacent to the other end of the arm 50. The user can raise or lower the head 10 along the rod 30. At this time, the minimum height and maximum height of the head 10 can be formed by the arm 50 being locked in the hole (30hh) formed in the rod 30.

[0146] The aforementioned pivoting, tilting, rotating, and lifting movements of the head 10 can be achieved independently of one another. 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 rotate within a range of +65 degrees to -65 degrees. For example, the head 10 can be positioned 1.065 to 1.265 mm from the base 20 or the ground in landscape mode.

[0147] Reference Figure 26The cradle 90 may include a front portion 91, a middle portion 92, and a rear portion 93. The middle portion 92 may be located behind the front portion 91 and coupled to the front portion 91. The rear portion 93 may be opposite to the front portion 91 across the middle portion 92 and coupled to the middle portion 92.

[0148] Reference Figure 27 and Figure 28 The front portion 91 may include a first portion 91a, a second portion 91b, and a third portion 91c. The front of the first portion 91a may be aligned with the rear cover 15 (see FIG. Figure 2 ) in the back of the rear cover 15. The front of the first part 91a can be curved. The second part 91b can be bent forward from the upper end of the first part 91a. The angle between the second part 91b and the first part 91a can be an obtuse angle. The third part 91c can be bent downward from the front end of the second part 91b. The angle between the third part 91c and the second part 91b can be a right angle or slightly greater than 90 degrees. Thus, the first part 91a can be in the shape of a part of the upper part of the curved disc cut away, and the second part 91b and the third part 91c can be in the shape of a hook as a whole.

[0149] At least one magnet 91M may be coupled to the first portion 91a. For example, the first magnet 91M1, the second magnet 91M2, and the third magnet 91M3 may be positioned in a groove formed on the back side of the first portion 91a. Preferably, the plurality of magnets 91M1, 91M2, and 91M3 may be symmetrically arranged on the first portion 91a.

[0150] The support portion 91V may be adjacent to the upper end of the first portion 91 and protrude rearward from the back surface of the first portion 91. The support portion 91V may extend in the left-right direction. The left-side fixing pin 91P1 may be fixed to one end of the support portion 91V, and the right-side fixing pin 91P2 may be fixed to the other end of the support portion 91V. The reinforcement portion 91S1 may be hook-shaped and inserted into the interior of the support portion 91V. For example, a single reinforcement portion 91S1 may extend long in the left-right direction along the support portion 91V. As another example, one of the pair of reinforcement portions 91S1 may be adjacent to the left-side fixing pin 91P1, and the other may be adjacent to the right-side fixing pin 91P2.

[0151] Reference Figure 29 The middle portion 92 can be placed on the back of the first portion 91a. The middle portion 92 can be shaped like the first portion 91a and penetrated by the support portion 91V. Figure 28 ) can be inserted into one side of the middle portion 92, and the right fixing pin 91P2 (refer to Figure 28) can be inserted into the other side of the middle portion 92. Thus, the middle portion 92 can be combined with the front portion 91. Meanwhile, the first left cover pin 92P1 can be aligned with the left fixing pin 91P1 and close the hole formed on one side of the middle portion 92. Furthermore, the first right cover pin 92P2 can be aligned with the right fixing pin 91P2 and close the hole formed on the other side of the middle portion 92.

[0152] The shaft retainers 92A, 92B may protrude rearward from a lower portion of the middle portion 92. For example, the shaft retainers 92A, 92B may include a first shaft retainer 92A and a second shaft retainer 92B spaced apart from each other in the left-right direction.

[0153] The first shaft holder 92A may include a first insertion portion 92a1 having a first insertion hole 92a2 and a first fixing portion 92a3 having a first fixing hole 92a4. A first fixing member 92a5 such as a nut may be fixed inside the first fixing portion 92a3 and aligned with the first fixing hole 92a4 and the first insertion hole 92a2.

[0154] The second shaft holder 92B may include a second insertion portion 92b1 having a second insertion hole 92b2 and a second fixing portion 92b3 having a second fixing hole 92b4. A second fixing member 92b5 such as a nut may be fixed inside the second fixing portion 92b3 and aligned with the second fixing hole 92b4 and the second insertion hole 92b2.

[0155] For example, the second shaft holder 92B and the first shaft holder 92A may be symmetrical.

[0156] The fixing pins 92S1 and 92S2 may protrude rearward from the lower portion of the middle portion 92. The fixing pins 92S1 and 92S2 may be adjacent to the shaft holders 92A and 92B. For example, the fixing pins 92S1 and 92S2 may include a first fixing pin 92S1 and a second fixing pin 92S2 spaced apart from each other in the left-right direction.

[0157] The first fixing pin 92S1 may be adjacent to the first shaft retainer 92A and protrude rearward from the back surface of the middle portion 92. The second fixing pin 92S2 may be adjacent to the second shaft retainer 92B and protrude rearward from the back surface of the middle portion 92. For example, the second fixing pin 92S2 may have the same shape as the first fixing pin 92S1.

[0158] Reference Figure 29 and Figure 30 , the rear portion 93 may be located behind the middle portion 92 and face the middle portion 92 .

[0159] Leaves 93A and 93B may protrude from the lower portion of the rear portion 93 toward the middle portion 92. Leaves 93A and 93B may be located between the insertion portions 92a1 and 92b1 and the fixing portions 92a3 and 92b3 of the shaft holders 92A and 92B. Fastening members 93F1 and 93F2, such as bolts, may penetrate the insertion portions 92a1 and 92b1, the leaves 93A and 93B, and the fixing portions 92a3 and 92b3, and be fastened to the fixing members 92a5 and 92b5. For example, the leaves 93A and 93B may include a first leaf 93A, which is penetrated by a first fastening member 93F1 between the first insertion portion 92a1 and the first fixing portion 92a3; and a second leaf 93B, which is penetrated by a second fastening member 93F2 between the second insertion portion 92b1 and the second fixing portion 92b3.

[0160] Thus, the rear portion 93 can rotate relative to the fastening members 93F1 and 93F2. In other words, the fastening members 93F1 and 93F2 can provide a hinge axis for the rear portion 93.

[0161] The elastic members 93S1 and 93S2 may be elastic and extend along the length of the fixing pins 92S1 and 92S2. The fixing pins 92S1 and 92S2 may be inserted into the elastic members 93S1 and 93S2. One end of the elastic members 93S1 and 93S2 may be fixed to the middle portion 92, and the other end of the elastic members 93S1 and 93S2 may be fixed to the rear portion 93. For example, the elastic members 93S1 and 93S2 may be springs. For example, the elastic members 93S1 and 93S2 may include a first elastic member 93S1 wrapped around the periphery of the first fixing pin 92S1 and a second elastic member 93S2 wrapped around the periphery of the second fixing pin 92S2.

[0162] Meanwhile, the left side portion 93L of the rear portion 93 may have a first hole through which the first fastening member 93F1 passes, and a first cover pin 93P1 may close the hole. Furthermore, the right side portion 93R of the rear portion 93 may have a second hole through which the second fastening member 93F2 passes, and a second cover pin (not shown) may close the second hole.

[0163] Reference Figure 26 and Figure 31 When the rear portion 93 rotates clockwise relative to the hinge axes 93F1 and 93F2 due to an external force applied to the rear portion 93, the elastic members 93S1 and 93S2 are compressed and elastically deformed. In other words, when the external force applied to the rear portion 93 is released, the elastic members 93S1 and 93S2 extend and return to their original position, and the rear portion 93 can rotate counterclockwise relative to the hinge axes 93F1 and 93F2 due to the elastic force of the elastic members 93S1 and 93S2.

[0164] Reference Figure 26In the initial state of the bracket 90 , the upper portion of the rear portion 93 may be in contact with or adjacent to the middle portion 92 .

[0165] Reference Figure 31 The user can rotate the rear portion 93 clockwise relative to the aforementioned hinge axes 93F1 and 93F1 and insert a terminal Mo, such as a smartphone, between the middle portion 92 and the rear portion 93. At this time, the rear portion 93 can apply pressure toward the middle portion 92 through the elastic force of the elastic members 93S1 and 93S2, thereby stably securing the terminal Mo to the bracket 90.

[0166] On the other hand, the middle pad 92V may protrude rearward from the back of the middle portion 92. In addition, the rear pad 93V may protrude forward from the rear portion 93. The pads 92V and 93V made of a cushioning material such as rubber or silicon can mitigate impact applied to the terminal Mo or minimize scratches on the terminal Mo caused by the bracket 90.

[0167] Refer again Figure 1 and Figure 2 , the hooks 91b, 91c of the bracket 90 can be stuck in the end frame 14. Specifically, the third portion 91c of the front portion 91 can be stuck in the horizontal portion 14H of the end frame 14 (refer to Figure 3 ), the second portion 91b may be located at the vertical portion 14V of the end frame 14 (refer to Figure 3 ), the first portion 91a may be located on the back surface of the rear cover 15. Thus, the bracket 90 may be detachably coupled to the periphery of the head 10.

[0168] Reference Figure 32 , the bracket 90 can be combined with any part of the periphery of the head 10. In addition, the bracket 90 can be connected to the head 10 by the magnet 91M (see Figure 27 ) and more strongly coupled to the head 10. For example, the position at which the bracket 90 is coupled to the head 10 by the magnetic force may correspond to the position of the plate 16 described later.

[0169] At least one plate 16 may be located on the frame 13 (see Figure 3 ) and the rear cover 15, and is coupled to the frame 13 and / or the rear cover 15. The plate 16 may be a magnetic substance such as iron (Fe). The plate 16 may be formed flat, or along the first portion 91a of the bracket 90 (refer to Figure 28 For example, the plate 16 may be plural.

[0170] The first plate 16a and the second plate 16b may be located adjacent to the upper edge of the head 10 and spaced apart from each other in the left-right direction. For example, the first plate 16a may be located to the left of a vertical line VL passing through the center O of the head 10, and the second plate 16b may be located to the right of the vertical line VL. The third plate 16c may be located adjacent to the left side of the head 10, and the fourth plate 16d may be located adjacent to the right side of the head 10. For example, the third plate 16c and the fourth plate 16d may be located on a horizontal line HL passing through the center O of the head 10, or slightly offset upward or downward from the horizontal line HL.

[0171] Thus, through the magnet 91M (refer to Figure 27 ) and the magnetic force between the plate 16, the bracket 90 can be more strongly coupled to the head 10 at the position of the plate 16.

[0172] On the other hand, a gyro sensor 17 can be mounted on the frame 13 between the frame 13 and the back cover 15. For example, the display device can have one gyro sensor 17. For example, the gyro sensor 17 can be located at a position separated from the vertical line VL and the horizontal line HL. As another example, the display device can have a plurality of gyro sensors 17. The detection value of the gyro sensor 17 can change according to the pivot angle of the head 10. Thus, the gyro sensor 17 can sense the pivoting of the head 10 and the mode of the head 10 (for example, landscape mode or portrait mode).

[0173] Reference Figure 33 and Figure 34 The control unit of the display device can be based on the gyro sensor 17 (refer to Figure 32 ) to detect the horizontal mode of the head 10 (refer to Figure 34 left side of the image) or portrait mode (see Figure 34 (right side figure) (S10).

[0174] The control unit may adjust the aspect ratio of the image according to the landscape mode or the portrait mode of the head 10 and output the image through the display panel 11 ( S11 ).

[0175] Reference Figure 35 The control unit C0 of the display device can control the operation of the display device and can be electrically connected to the components of the display device.

[0176] The display panel 11, the main board Mb, the power board Pu and the T-CON board Tc (Timing Controller board) can be electrically connected to the control unit C0. The main board Mb, the power board Pu and the T-CON board Tc can be mounted on the frame 13 (see Figure 3) on the back. The motherboard Mb can control the display device. The control unit C0 can be implemented by the motherboard MB or can be a higher-level control unit that controls the motherboard Mb. The power supply board Pu can be connected to the battery Bt (refer to Figure 1 ) and / or an external power source receives power and provides power to various components of the display device. The T-CON board Tc can provide an image signal to the display panel 110.

[0177] The speaker (SPK) may be electrically connected to the control part CO. The speaker (SPK) may be provided at the head 10, the rod 30, the arm 50 and / or the base 20, and provide sound.

[0178] The gyro sensor 17 may be electrically connected to the control unit C0 .

[0179] The communication unit Cm may include an NFC (Near Field Communication) module N1 and / or a Wi-Fi (Wireless High Fidelity) module N2. Figure 13 ) can be installed on the frame 13 between the frame 13 and the back cover 15, and adjacent to the right and lower sides of the head 10. The user can connect the head 10 and the terminal Mo by tagging the terminal to the NFC module N1. The Wi-Fi module N2 (refer to Figure 13 ) can be installed on the frame 13 between the frame 13 and the back cover 15, and adjacent to the upper side of the head 10. The head 10 can be connected to the network through the Wi-Fi module N2.

[0180] The input unit Pm can be electrically connected to the control unit C0. The user can input instructions or signals to the control unit C0 through the input unit Pm. For example, the input unit Pm can be a key Bu, a display panel 11 and / or a microphone Mc. The key Bu (refer to Figure 32 ) can be installed on the frame 13 between the frame 13 and the back cover 15, and is adjacent to the left and bottom sides of the head 10. The user can control the head 10 by operating the button Bu. The display panel 11 can be implemented in a touch-sensitive manner, and the user can control the display device by touching the display panel 11. The microphone Mc can be provided on the display device, and the user can control the display device by inputting voice into the microphone Mc. For example, the input part Pm can be a remote controller Rc (remote controller) operated by the user and communicating with the display device, or an application (App) provided on the user's terminal (smartphone) and communicating with the display device.

[0181] Reference Figure 35 and Figure 36The motor 410 can be coupled to the back of the frame 13 via a motor bracket 410a. The motor 410 can be a motor capable of adjusting the rotation direction, rotation angle, and speed. The motor 410 can be a stepping motor.

[0182] A worm 413 (worm) can be fixed to the rotating shaft 411 of the motor 410 via a coupling member 412 and rotate together with the rotating shaft 411. A worm wheel 414 (worm wheel) can engage with a thread formed on the outer circumference of the worm 413. The rotating axis of the worm 413 can be parallel to the left-right direction, and the rotating axis of the worm wheel 414 can be parallel to the up-down direction.

[0183] A drive shaft 44 s of the pivot shaft 44 may be opposite to the main body 44 b across the head 44 a and fixed to the worm wheel 414 .

[0184] Thus, when the motor 410 is driven, the pivot shaft 44 can rotate in a first rotation direction or a second rotation direction opposite to the first rotation direction. Figure 24 ) can pivot automatically.

[0185] The disc indicator 418 may be adjacent to and fixed to the end of the worm 413. The disc indicator 418 may include a plurality of holes (not labeled) spaced apart from each other in a circumferential direction of the disc indicator 418.

[0186] The rotation sensor 419 may be adjacent to the disc indicator 418 and fixed to one side of the gear box 410b of the frame 13, which houses the worm 413 and the worm wheel 414. The rotation sensor 419 may be in the shape of a horseshoe. The light emitting portion and the light receiving portion of the rotation sensor 419 may face each other and be spaced apart from each other. As the worm 413 rotates, the disc indicator 418 may rotate by passing between the light emitting portion and the light receiving portion. In response to the rotation of the disc indicator 418, the light from the light emitting portion may pass through the hole in the disc indicator 418 or be blocked by the disc indicator 418.

[0187] Thus, the rotation sensor 419 can sense the rotation speed and / or the rotation amount of the motor 410 .

[0188] The aforementioned motor 410 and the rotation sensor 419 can be electrically connected to the control unit C0. That is, the control unit C0 can adjust the action of the motor 410 based on the information obtained by the rotation sensor 419, thereby controlling the head 10 (see Figure 24 ) pivot.

[0189] Reference Figure 37 and Figure 38The user's terminal Mo can communicate with the communication unit Cm (refer to Figure 35 ) communicates with the head 10. That is, the user can tag the terminal Mo with the NFC module N1 (refer to Figure 35 ) or connect the head 10 to the network via the Wi-Fi module N2 and mirror the screen of the terminal Mo to the head 10 (S20).

[0190] The control unit C0 may recognize the landscape mode or the portrait mode of the terminal Mo based on the information acquired from the terminal Mo via the communication unit Cm ( S21 ).

[0191] The control unit C0 can pivot the head 10 in accordance with the horizontal mode or the vertical mode of the terminal Mo (S22). When the terminal Mo is in the horizontal mode, the control unit C0 can pivot the head 10 by adjusting the motor 410 (refer to Figure 36 ) causes the head 10 to pivot to the horizontal mode (refer to Figure 38 When the terminal Mo is in the vertical mode, the control unit C0 can adjust the motor 410 (see Figure 36 ) causes the head 10 to pivot to a longitudinal mode (refer to Figure 38 on the right side of the diagram).

[0192] The control unit C0 may adjust the aspect ratio of the image according to the landscape mode or the portrait mode of the head 10 and output the image through the display panel 11 ( S23 ).

[0193] Reference Figures 39 to 41 The control unit C0 can be based on the gyro sensor 16 (refer to Figure 32 ) to identify the terminal Mo placed on the head 10 using the bracket 90 (S30). The display panel of the terminal Mo can be set on the front of the terminal Mo, and the camera Mv of the terminal Mo can be set on the back of the terminal Mo.

[0194] The control unit C0 may recognize the position of the terminal Mo placed on the head 10 based on the information acquired from the gyro sensor 16 ( S31 ).

[0195] The control unit C0 may pivot the head 10 in accordance with the recognized position of the terminal Mo ( S32 ).

[0196] Reference Figure 40(a) In the landscape mode of the head 10, if the terminal Mo is located at position P1 corresponding to the fourth plate 16d, the control unit C0 can switch the head 10 from the landscape mode to the portrait mode by rotating the head 10 90 degrees clockwise. If the terminal Mo is located at position P4 corresponding to the third plate 16c, the control unit C0 can switch the head 10 from the landscape mode to the portrait mode by rotating the head 10 90 degrees counterclockwise.

[0197] In addition, in the landscape mode of the head 10 , if the terminal Mo is located at the position P2 corresponding to the second plate 16 b or the position P3 corresponding to the first plate 16 a , the control portion C0 may maintain the landscape mode of the head 10 .

[0198] Reference Figure 40 (b), in the first longitudinal mode of the head 10, the first plate 16a and the second plate 16b may be adjacent to the left side of the head 10. In the first longitudinal mode of the head 10, if the terminal Mo is located at the position Q1 corresponding to the second plate 16b or the position Q2 corresponding to the first plate 16a, the control unit C0 may convert the head 10 from the first longitudinal mode to the landscape mode by rotating the head 10 90 degrees counterclockwise.

[0199] In addition, in the first longitudinal mode of the head 10 , if the terminal Mo is located at the position Q3 corresponding to the fourth plate 16 d , the control unit C0 may maintain the first longitudinal mode of the head 10 .

[0200] In addition, in the first longitudinal mode of the head 10, if the terminal Mo is located at the position Q4 corresponding to the third plate 16c, the control unit C0 can convert the head 10 from the first longitudinal mode to the second longitudinal mode described later by rotating the head 10 180 degrees counterclockwise.

[0201] Reference Figure 40 (c), in the second longitudinal mode of the head 10, the first plate 16a and the second plate 16b may be adjacent to the right side of the head 10. In the second longitudinal mode of the head 10, if the terminal Mo is located at the position R1 corresponding to the first plate 16a or the position R2 corresponding to the second plate 16b, the control unit C0 may convert the head 10 from the second longitudinal mode to the landscape mode by rotating the head 10 90 degrees in the clockwise direction.

[0202] In addition, in the second longitudinal mode of the head 10 , if the terminal Mo is located at the position R3 corresponding to the third plate 16 c , the control portion C0 may maintain the second longitudinal mode of the head 10 .

[0203] In addition, in the second longitudinal mode of the head 10, if the terminal Mo is located at the position R4 corresponding to the fourth plate 16d, the control unit C0 can convert the head 10 from the second longitudinal mode to the first longitudinal mode by rotating the head 10 180 degrees clockwise.

[0204] The control unit C0 may adjust the aspect ratio of the image according to the landscape mode or the portrait mode of the head 10 and output the image through the display panel 11 ( S33 ).

[0205] Reference Figure 35 and Figure 42 , the wireless charging unit 19 can be located between the plate 16 and the back cover 15. The wireless charging unit 19 can be combined with the frame 13 (refer to Figure 3 ) and / or back cover 15. The wireless charging unit 19 can provide power to the electronic device in a wireless manner through inductive coupling or resonant coupling. Such a wireless charging unit 19 can receive power from the power supply board Pu.

[0206] Inductive coupling utilizes the principle that changing the intensity of the current flowing through one of two adjacent coils causes a change in the magnetic field. This changes the magnetic flux through the other coil, generating an induced electromotive force. In other words, even if the two wires do not move spatially, simply changing the current in one coil while keeping the two coils adjacent to each other generates an induced electromotive force in the other coil. While this significantly affects frequency characteristics, power efficiency may be affected by the alignment and distance between the transmitter (i.e., wireless charging unit) and receiver (i.e., terminal) that contain the coils.

[0207] The resonance coupling method uses the following principle: when a resonant frequency is applied to any one of two coils separated by a specified distance, a portion of the magnetic field change generated is applied to the other coil with the same resonant frequency, thereby generating an induced electromotive force. In other words, when the transmitting device and the receiving device resonate at the same frequency, the electromagnetic waves are transmitted through the close electromagnetic field, so when the frequencies are different, there is no energy transfer. In this case, the choice of frequency may become an important issue. In addition, since there is no energy transfer between different resonant frequencies, the choice of resonant frequency can also be used to limit the devices to be charged.

[0208] The wireless charging unit 19 may include a PCB 19 a (Printed Circuit Board) and a coil 19 b (coil) electrically connected to the PCB 19 a. The coil 19 b can wirelessly charge the terminal Mo placed in the charging area 15A of the rear cover 15.

[0209] Thus, the bracket 90 (see Figure 2 ) The terminal Mo is placed on the rear cover 15 and can be wirelessly charged by facing the coil 19b across the charging area 15A. For example, each of the plurality of wireless charging units 19 can be located on each of the plurality of plates 16a, 16b, 16c, and 16d. In other words, the display device can provide multiple wireless charging areas.

[0210] The wireless charging unit 19 can be electrically connected to the control unit C0. The control unit C0 can be based on the gyro sensor 16 (refer to Figure 32 ) to identify the position of the terminal Mo placed on the head 10. If the control unit C0 recognizes that the terminal Mo is placed on the head 10 so as to overlap the charging area 15A, the control unit C0 can activate the wireless charging unit 19. The control unit C0 can only activate the wireless charging unit 19 corresponding to the position of the terminal Mo among the multiple wireless charging units 19.
