The first holder (1610) may be formed in the center of the right side of the first side frame (161). The first holder (1610) may include parts (1611, 1612, 1613) spaced apart from each other. An upper groove (161U) may be formed between the upper part (1611) and the middle part (1612). A lower groove (161L) may be formed between the middle part (1612) and the lower part (1613). A third groove (151B) may be formed at the other end of the first arm (151). The middle part (1612) can be inserted into the third groove (151B), and the parts (1511, 1512) of the first arm (151) forming the third groove (151B) can be inserted into the upper groove (161U) and the lower groove (161L). The first shaft (161P) can pass through the parts (1611, 1612, 1613) and the parts (1511, 1512) of the first arm (151). The first side frame (161) can be rotatably coupled to the first arm (151) around the first shaft (161P). The first side frame (161) can be rotated in response to the movement of the first arm (151).

[0084] The second holder (1620) may protrude from the second side frame (162) toward the second arm (152). The second holder (1620) may be formed in the center of the left side of the second side frame (162). The second holder (1620) may include parts (1621, 1622, 1623) spaced apart from each other. An upper groove (162U) may be formed between the upper part (1621) and the middle part (1622). A lower groove (162L) may be formed between the middle part (1622) and the lower part (1623). A fourth groove (152B) may be formed at the other end of the second arm (152). The middle part (1622) can be inserted into the fourth groove (152B), and parts (1521, 1522) of the second arm (152) forming the fourth groove (152B) can be inserted into the upper groove (162U) and the lower groove (162L). The second shaft (162P) can pass through the parts (1621, 1622, 1623) and parts (1521, 1522) of the second arm (152). The second side frame (162) can be rotatably coupled to the second arm (152) around the second shaft (162P). The second side frame (162) can be rotated in response to the movement of the second arm (152).

[0085]

[0086] Referring to FIG. 13 together with FIG. 11, the links (141, 142) and arms (151, 152) can be rotated in response to the driving of the actuator (140A). The rotation shaft of the motor (140B) of the actuator (140A) can be rotated in a first rotational direction or a second rotational direction opposite to the first rotational direction. The rods (140C1, 140C2) of the actuator (140A) can push or pull the links (141, 142).

[0087] Corresponding to the rotation of the rotation shaft of the motor (140B) in the first rotational direction, the first rod (140C1) can move to the left, and the second rod (140C2) can move to the right. The first link (141) can be rotated counterclockwise by the first rod (140C1) moving to the left, and the first arm (151) connecting the first link (141) and the first side frame (161) can also be rotated counterclockwise. The second link (142) can be rotated clockwise by the second rod (140C2) moving to the right, and the second arm (152) connecting the second link (142) and the second side frame (162) can also be rotated clockwise. Accordingly, the left side (11L) and the right side (11R) of the display panel (11) can move forward. As the driving time of the motor (140B) increases, the curvature of the display panel (11) can increase.

[0088] In response to the rotation of the rotation shaft of the motor (140B) in the second rotational direction, the first rod (140C1) can move to the right, and the second rod (140C2) can move to the left. The first link (141) can be rotated clockwise by the first rod (140C1) moving to the right, and the first arm (151) connecting the first link (141) and the first side frame (161) can also be rotated clockwise. The second link (142) can be rotated counterclockwise by the second rod (140C2) moving to the left, and the second arm (152) connecting the second link (142) and the second side frame (162) can also be rotated counterclockwise. Accordingly, the left side (11L) and the right side (11R) of the display panel (11) can move backward. As the driving time of the motor (140B) increases, the curvature of the display panel (11) can be reduced.

[0089] The links (141, 142) can pivot around the front shafts (140P1, 140Q1). The rear shafts (140P2, 140Q2) connecting the rods (140C1, 140C2) and the links (141, 142) can trace a circular trajectory with respect to the front shafts (140P1, 140Q1). When the display panel (11) and the plate (12) are flat, the rear shafts (140P2, 140Q2) and the rods (140C1, 140C2) can be located at a first level (L1). When the display panel (11) and the plate (12) are bent to the maximum, the rear shafts (140P2, 140Q2) and the rods (140C1, 140C2) may be located at a second level (L2). When the display panel (11) and the plate (12) are bent to a specific curvature smaller than the maximum curvature, the rear shafts (140P2, 140Q2) and the rods (140C1, 140C2) may be located at a third level (L3). With respect to the frame (140), the third level (L3) may be located higher than the first level (L1) and the second level (L2). With respect to the frame (140), the first level (L1) and the second level (L2) may be located at the same height. When the rear shafts (140P2, 140Q2) are located at the third level (L3), the wings (1411, 1412, 1421, 1422) of the links (141, 142) can be perpendicular to the frame (140).

[0090] Accordingly, the height of the actuator (140A) having rods (140C1, 140C2) connected to rear shafts (140P2, 140Q2) can be changed in response to the driving of the actuator (140A). Specifically, as the position of the rods (140C1, 140C2) moves from a first level (L1) to a second level (L2), the actuator (140A) can be moved rearward from the frame (140). As the position of the rods (140C1, 140C2) moves from the second level (L2) to a third level (L3), the actuator (140A) can be moved toward the frame (140). An actuator (140A) having rods (140C1, 140C2) located at the second level (L2) can be lifted from the frame (140). That is, the actuator (140A) can be driven while lifted so that vibration and noise of the actuator (140A) can be minimized.

[0091]

[0092] Referring to FIG. 14, the cover (143) may cover the rear of the actuator (140A) and may be coupled to the frame (140). The actuator (140A) may be located in the internal space (143S) of the cover (143). The rear part (143R) of the cover (143) may form the rear of the cover (143) and may form the rear boundary of the internal space (143S). The rear part (143R) may be adjacent to but spaced apart from the rear of the actuator (140A). The distance (Dr) between the rear of the actuator (140A) and the front of the rear part (143R) may vary depending on the height change of the actuator (140A) relative to the frame (140), and the minimum value of the distance (Dr) may be greater than 0.

[0093] Accordingly, the actuator (140A) that rises from the rear of the frame (140) or lowers toward the frame (140) may not be interfered with by the cover (143).

[0094]

[0095] Referring to FIG. 15, a pair of ribs (140M) may protrude from the rear of the frame (140) and may be adjacent to the first housing (140D1). The pair of ribs (140M) may be spaced apart from each other in the direction of movement of the first rod (140C1).

[0096] A flange (140N, flange) can protrude from the side of the first housing (140D1) and can be inserted between a pair of ribs (140M).

[0097] Accordingly, in the direction of movement of the first rod (140C1), i.e., the horizontal direction, the movement of the actuator (140A) can be restricted by the flange (140N) engaging with the ribs (140M). Also, in the front-rear direction, the ribs (140M) can guide the upward or downward movement of the actuator (140A) relative to the frame (140).

[0098]

[0099] Referring again to FIG. 11, the sensor (S) may be coupled to the rear of the frame (140). The sensor (S) may be coupled to the inside of the cover (143, see FIG. 14). The first sensor (S1) may be adjacent to the first link (141). The first sensor (S1) may be spaced a certain distance rearward from the rear of the frame (140). The second sensor (S2) may be adjacent to the second link (142). The second sensor (S2) may be located closer to the rear of the frame (140) than the first sensor (S1).

[0100] For example, the sensor (S) may be a photo sensor. The sensor (S) may have an overall horseshoe shape. The sensor (S) may include a light-emitting part (Sa) and a light-receiving part (Sb) that are spaced apart from each other. The light-emitting part (Sa) may emit light in the infrared wavelength range toward the light-receiving part (Sb), and the light-receiving part (Sb) may detect the light from the light-emitting part (Sa). If an object exists between the light-emitting part (Sa) and the light-receiving part (Sb), the light from the light-emitting part (Sa) may not reach the light-receiving part (Sb), thereby allowing the sensor (S) to detect the object.

[0101] The first protrusion (1413) may protrude from at least one of the first wings (1411, 1412) of the first link (141). The first protrusion (1413) may extend in a direction intersecting the first wing (1411). In response to the rotation of the first link (141), the first protrusion (1413) may trace a circular trajectory, and the circular trajectory may pass through the space between the light-emitting part (Sa) and the light-receiving part (Sb) of the first sensor (S1). When the display panel (11) and the plate (12) are bent to the maximum curvature (see solid line in FIG. 13), the first protrusion (1413) may be located between the light-emitting part (Sa) and the light-receiving part (Sb), and the first sensor (S1) may detect the first protrusion (1413). Accordingly, the first sensor (S1) can detect whether the display panel (11) and the plate (12) are bent to the maximum curvature. When the display panel (11) and the plate (12) are bent to the maximum curvature (see solid line in FIG. 13), a control unit (C, see FIG. 21) electrically connected to the first sensor (S1) via the first cable (Ca) can stop the operation of the actuator (140A) which is operated to bend the display panel (11) and the plate (12).

[0102] The second protrusion (1423) may protrude from at least one of the second wings (1421, 1422) of the second link (142). The second protrusion (1423) may extend in a direction intersecting the second wing (1421). In response to the rotation of the second link (142), the second protrusion (1423) may trace a circular trajectory, and the circular trajectory may pass through the space between the light-emitting part (Sa) and the light-receiving part (Sb) of the second sensor (S2). When the display panel (11) and the plate (12) are flat (see the dotted line in FIG. 13), the second protrusion (1423) may be located between the light-emitting part (Sa) and the light-receiving part (Sb), and the second sensor (S2) may detect the second protrusion (1423). Accordingly, the second sensor (S2) can detect whether the display panel (11) and the plate (12) are flattened. If the display panel (11) and the plate (12) are flattened (see dotted line in FIG. 13), the control unit (C, see FIG. 21) electrically connected to the second sensor (S2) via the second cable (Cb) can stop the operation of the actuator (140A) which operates to flatten the display panel (11) and the plate (12).

[0103] For example, the first angle between the first protrusion (1413) and the first wing (1411) may be equal to the second angle between the second protrusion (1423) and the second wing (1421).

[0104] Meanwhile, in addition to the first sensor (S1) and the second sensor (S2), a third sensor (S3, not shown) may be located on the first link (141) or the second link (142). The third sensor (S3) may be located closer to the rear of the frame (140) than the first sensor (S1), but further from the rear of the frame (140) than the second sensor (S2). In this case, the third protrusion (1414; 1424) may extend from the first wing (1412) or the second wing (1422), and the third sensor (S3) may detect the third protrusion (1414; 1424). For example, the third angle between the third protrusion (1414; 1424) and the wing (1412; 1422) may be the same as the first angle. Accordingly, the third sensor (S3) can detect whether the display panel (11) and the plate (12) are bent at a specific curvature smaller than the maximum curvature.

[0105]

[0106] Referring to FIGS. 16 to 18, the controller (50) may be adjacent to the lower edge (11D) of the display panel (11). The controller (50) may be positioned in the center of the lower edge (11D). The controller (50) may include a housing (51) and fins (52).

[0107] The housing (51) may be located at the rear of the display panel (11). The housing (51) may be extended horizontally. The housing (51) may protrude downward from the lower edge (11D) of the display panel (11). The fixing part (51F) may protrude from the upper edge of the housing (51). The fixing pin (12F) may protrude from the rear of the plate (12) and may be inserted into the fixing part (51F). The fixing pin (12F) may be located on a vertical line (VV'). The outer diameter of the fixing pin (12F) may be substantially equal to the diameter of the hole in the fixing part (51F) into which the fixing pin (12F) is inserted. A fastening member (F), such as a screw, may be fastened to the fixing pin (12F), and the rear of the fixing part (51F) may be caught on the head (Fh) of the fastening member (F). Accordingly, the housing (51) can be fixed to the plate (12).

[0108] A button (51P) may be mounted on the rear of the housing (51). A user can turn on the power of the display (10) by pressing the button (51P). The button (51P) may be a joystick, and the user can control the display (10) by operating the button (51P). An antenna may also be mounted in the internal space of the housing (51).

[0109] Pins (52) may protrude from the rear of the housing (51). Pins (52) may be arranged along the longitudinal direction (i.e., left-right direction) of the housing (51). Pins (52) may be spaced apart from each other. Vent holes may be formed between the pins (52).

[0110]

[0111] Referring again to FIG. 16, a bottom grille (40) may be positioned along the lower edge (11D) of a display panel (11). The bottom grille (40) may be referred to as a bottom vent member (40). The bottom grille (40) may include a first bottom grille (41) and a second bottom grille (42). A controller (50) may be positioned between the first bottom grille (41) and the second bottom grille (42). The bottom grille (40) may be referred to as a second grille (40). The second grille (40) may be flexible.

[0112]

[0113] Referring to FIG. 19 together with FIG. 16, the first bottom grille (41) may be located at the rear of the display panel (11). The first bottom grille (41) may extend along the lower edge (11D) of the display panel (11). The first bottom grille (41) may include a body (411) and fins (412).

[0114] The body (411) may extend along the lower edge (11D) adjacent to the lower edge (11D) of the display panel (11). A coupling pin (12a) may protrude from the rear surface of the plate (12) and may be inserted into the coupling portion (411F) of the body (411). The coupling pin (12a) may be spaced to the left from the vertical line (VV'). The outer diameter of the coupling pin (12a) may be smaller than the diameter of the hole (411Fh) in the coupling portion (411F) into which the coupling pin (12a) is inserted. A fastening member (Fa), such as a screw, may be fastened to the coupling pin (12a), and the rear surface of the coupling portion (411F) may be caught on the head (Fah) of the fastening member (Fa).

[0115] Accordingly, the body (411) can be coupled to the rear of the plate (12). If the plate (12) is flat (see dashed line in FIG. 13), the coupling pin (12a) can be positioned to the right of the center of the hole (411Fh). As the plate (12) becomes more curved (see solid line in FIG. 13), the coupling pin (12a) can be moved to the left within the hole (411Fh). That is, in response to the change in curvature of the plate (12), the plate (12) can be slipped relative to the body (411).

[0116] Pins (412) may protrude from the rear of the body (411). Pins (412) may be arranged along the length of the body (411) (i.e., left-right direction). Pins (412) may be spaced apart from each other. Vent holes may be formed between the pins (412).

[0117]

[0118] Referring to FIG. 20 together with FIG. 16, the second bottom grill (42) may be located at the rear of the display panel (11). The second bottom grill (42) may extend along the lower edge (11D) of the display panel (11). The second bottom grill (42) may include a body (421) and fins (422).

[0119] The body (421) may extend along the lower edge (11D) adjacent to the lower edge (11D) of the display panel (11). A coupling pin (12b) may protrude from the rear surface of the plate (12) and may be inserted into the coupling portion (421F) of the body (421). The coupling pin (12b) may be spaced to the right from the vertical line (VV'). The outer diameter of the coupling pin (12b) may be smaller than the diameter of the hole (421Fh) in the coupling portion (421F) into which the coupling pin (12b) is inserted. A fastening member (Fb), such as a screw, may be fastened to the coupling pin (12b), and the rear surface of the coupling portion (421F) may be caught on the head (Fbh) of the fastening member (Fb).

[0120] Accordingly, the body (421) can be coupled to the rear of the plate (12). If the plate (12) is flat (see dashed line in FIG. 13), the coupling pin (12b) can be positioned to the left of the center of the hole (421Fh). As the plate (12) becomes more curved (see solid line in FIG. 13), the coupling pin (12b) can be moved to the right within the hole (421Fh). That is, in response to the change in curvature of the plate (12), the plate (12) can be slipped relative to the body (421).

[0121] Pins (422) may protrude from the rear of the body (421). Pins (422) may be arranged along the length of the body (421) (i.e., left-right direction). Pins (422) may be spaced apart from each other. Vent holes may be formed between the pins (422).

[0122]

[0123] Referring again to FIG. 1, a top grille (30) may be positioned along the upper edge of a display panel (11). The top grille (30) may be attached to the rear of a plate (12, see FIG. 13) adjacent to the upper edge of the display panel (11). The top grille (30) may be opposite to the bottom grille (40, see FIG. 16). The top grille (30) may be referred to as a top vent member (30). The top grille (30) may have the same or corresponding shape as the bottom grille (40). The fins (32) of the top grille (30) may intersect the display panel (11) and may be arranged along the upper edge of the display panel (11). A vent hole may be formed between the fins (32). The top grille (30) may be referred to as a first grille (30). The first grill (30) can be flexible.

[0124] Accordingly, the internal space of the display (10) can be communicated with the outside of the display (10) through the gaps between the pins (32) of the top grill (30), the gaps between the pins (412, 422) of the bottom grill (40) (see FIG. 16), and the gaps between the pins (52) of the controller (50) (see FIG. 16). Heat from the display (10) can be released to the outside by air passing through the gaps.

[0125] The fins (32, 412, 422, 52) can form a rearwardly convex parabola. The height of the fins (32, 412, 422, 52) protruding rearward from the plate (12, see FIG. 3) can gradually decrease from the center of the fins (32, 412, 422, 52) toward the outer edge of the fins (32, 412, 422, 52). The upper edge of the back cover (18) can extend along the fins (32). The lower edge of the back cover (18) can extend along the fins (412, 422, 52). The left edge of the back cover (18) can extend in a straight line and can be located on the first side frame (161, see FIG. 13). The right side of the back cover (18) can be extended in a straight line and can be located on the second side frame (162, see FIG. 13).

[0126]

[0127] Referring to FIGS. 21 and 22, the back cover (18) may cover the rear of the plate (12, see FIG. 3). The back cover (18) may cover components attached to the rear of the plate (12), such as the drive module (14), arms (151, 152), and side frames (161, 162). Pins (32, 412, 422, 52, see FIG. 1 and 16) may be located between the plate (12) and the back cover (18). The back cover (18) may be curved along the pins (32, 412, 422, 52) (see FIG. 1). The back cover (18) may be flexible. The back cover (18) may be bent or unfolded together with the display panel (11) and the plate (12).

[0128] The hole (18H) may be formed in the center of the back cover (18). For example, the hole (18H) may have a hexagonal shape. Electronic components (EP) may be located inside the hole (18H) and may be coupled to the rear of the plate (12, see FIG. 3).

[0129] The central cover (19) can cover the hole (18H) and can be coupled to the back cover (18). The holes (19h) can be formed in the central cover (19). The mount (19M) can be formed in the central part of the central cover (19) and can be equipped with the holes (19h). The column (4, see FIG. 1) of the stand (2) can be mounted on the mount (19M).

[0130]

[0131] Referring to FIGS. 23 and 24, the back cover (18) may be curved convexly toward the rear. A plurality of latches (180) may be formed on the inner surface, i.e., the front, of the back cover (18). The latches (180) may include upper latches (180U) formed on the upper part of the back cover (18) and lower latches (180L) formed on the lower part of the back cover (18). The upper latches (180U) and the lower latches (180L) may be symmetrical vertically.

[0132] The upper latches (180U) may have the same shape as each other. The upper latches (180U) may be grouped in pairs. A pair of upper latches (180U) may be spaced apart vertically and aligned vertically. For example, a total of six pairs of upper latches (180U) may be arranged along the upper edge of the back cover (18). The upper latch (180U) may include a protrusion (180Ua) and a hook (180Ub). The protrusion (180Ua) may protrude from the inner surface of the back cover (18). The hook (180Ub) may be bent downward from the protrusion (180Ua). The hook (180Ub) may be referred to as a bent portion (180Ub).

[0133] Lower latches (180L) may have the same shape as each other. Lower latches (180L) may be grouped in pairs. A pair of lower latches (180L) may be spaced apart vertically and aligned vertically. For example, a total of six pairs of lower latches (180L) may be arranged along the lower edge of the back cover (18). The lower latch (180L) may include a protrusion (180La) and a hook (180Lb). The protrusion (180La) may protrude from the inner surface of the back cover (18). The hook (180Lb) may be bent upward from the protrusion (180La). The hook (180Lb) may be referred to as a bent portion (180Lb).

[0134]

[0135] Referring to FIG. 25, a plurality of holders (17) may be coupled to the rear of the plate (12). The holders (17) may be referred to as sliding latches (17). The plurality of holders (17) may include upper holders (17U) arranged along the upper edge of the plate (12) and lower holders (17L) arranged along the lower edge of the plate (12). The upper holders (17U) and the lower holders (17L) may be symmetrical vertically. That is, the description of the upper holders (17U) may be applied to the lower holders (17L). Also, the description of the lower holders (17L) may be applied to the upper holders (17U). The upper holder (17U) can be referred to as the first holder (17U), and the lower holder (17L) can be referred to as the second holder (17L).

[0136] For example, three of the six upper holders (17U) can be positioned between the first side frame (161) and the vertical line (VV') and between the first arm (151) and the top grille (30). The remaining three upper holders (17U) can be positioned between the vertical line (VV') and the second side frame (162) and between the second arm (152) and the top grille (30).

[0137] For example, three of the six lower holders (17L) can be positioned between the first side frame (161) and the vertical line (VV') and between the first arm (151) and the first bottom grill (41). The remaining three lower holders (17L) can be positioned between the vertical line (VV') and the second side frame (162) and between the second arm (152) and the second bottom grill (42).

[0138] Meanwhile, the top grill (30) may include a body (31) and fins (32). The fixing part (31F) of the body (31) may be located on a vertical line (VV') and may be fixed to a fixing pin (12FF, see FIG. 3) of the plate (12), such as the combination of the fixing part (51F) and the fixing pin (12F) (see FIG. 17). The first connecting part (311) of the body (31) may be spaced to the left from the vertical line (VV') and may be connected to a first connecting pin (12c, see FIG. 3) of the plate (12), such as the combination of the connecting part (411F) and the connecting pin (12a) (see FIG. 19). The second coupling portion (312) of the body (31) may be spaced to the right from the vertical line (VV') and may be coupled to the second coupling pin (12d, see FIG. 3) of the plate (12), such as the coupling of the coupling portion (421F) and the coupling pin (12b) (see FIG. 20).

[0139]

[0140] Referring to FIG. 26, the holder (17) may include a fixed body (171) and a moving body (172).

[0141] The fixed body (171) may be extended vertically. The fixed body (171) may be positioned on the rear surface of the plate (12). A first pin (171P, pin) and a second pin (171Q, pin) may protrude rearward from the rear surface of the fixed body (171). The first pin (171P) and the second pin (171Q) may be spaced apart from each other in the longitudinal direction, i.e., the vertical direction, of the fixed body (171). Fastening members, such as screws, may be fastened to the fixed pins (12P, see FIG. 3, fixed pins) of the plate (12) through the pins (171P, 171Q, pins). Accordingly, the fixed body (171) may be fixed to the plate (12).

[0142] The third pin (171S) may protrude rearward from the rear of the fixed body (171) and may be spaced horizontally from the second pin (171Q). In the vertical direction, the second pin (171Q) may be located between the first pin (171P) and the third pin (171S). The second pin (171Q) may be located closer to the third pin (171S) than to the first pin (171P). The third pin (171S) may be referred to as a support pin (171S).

[0143] The first rib (1711) may protrude rearward from the rear of the fixed body (171). The width of the first rib (1711) may correspond to the width of the fixed body (171). The first rib (1711) may be adjacent to the first pin (171P). The first pin (171P) may be located between the first rib (1711) and the second rib (1712).

[0144] The second rib (1712) may protrude rearward from the rear of the fixed body (171). The width of the second rib (1712) may correspond to the width of the fixed body (171). The second rib (1712) may be adjacent to the second pin (171Q). The second pin (171Q) may be located between the second rib (1712) and the third pin (171S).

[0145] The movable body (172) may be located on the rear surface of the fixed body (171). The movable body (172) may extend along the fixed body (171). A slot (172P) may be formed in the movable body (172). The slot (172P) may be a long hole along the longitudinal direction of the fixed body (171). A first pin (171P) may be inserted into the slot (172P), and the length of the slot (172P) may be greater than the width (diameter) of the first pin (171P). The slot (172P) may move relative to the first pin (171P). A projection (171t) may protrude from the fixed body (171) and may be inserted into a slit (172t) of the movable body (172). The slit (172t) may move relative to the projection (171t).

[0146] The first coupler (1721) may protrude rearward from the rear of the movable body (172). The first rib (1711) may be inserted into the first coupler (1721). The parts (1721a, 1721b, 1721c, 1721d, 1721e) of the first coupler (1721) may form an internal space of the first coupler (1721) where the first rib (1711) is located. The inner part (1721a) may be located between the first rib (1711) and the first pin (171P). The catch portion (1721b) may be bent toward the first rib (1711) from the rear end of the inner part (1721a). The outer part (1721c) may be opposite to the inner part (1721a) with respect to the first rib (1711). The outer part (1721c) may face the top grille (30) or the bottom grille (40, see FIG. 25). The side parts (1721d, 1721e) may form the lateral side of the first coupler (1721).

[0147] The second coupler (1722) may protrude rearward from the rear of the movable body (172). The second rib (1712) may be adjacent to the second coupler (1722). Parts (1722a, 1722b, 1722c, 1722d) of the second coupler (1722) may extend along the circumference of the second rib (1712). The inner part (1722a) may be located between the second rib (1712) and the second pin (171Q). The catch (1722b) may be bent toward the second rib (1712) from the rear end of the inner part (1722a). Side parts (1722c, 1722d) may form the lateral side of the second coupler (1722).

[0148] Accordingly, the movable body (172) can be coupled to the fixed body (171) so as to be movable along the longitudinal direction of the fixed body (171). The rear surface of the movable body (172) can be caught on the heads of screws fastened to the pins (171P, 171Q).

[0149] The supporter (1723) may protrude from the inner part (1722a) of the second coupler (1722). The supporter (1723) may extend from one side of the inner part (1722a) toward the second pin (171Q). The supporter (1723) may include a first part (1723a) extending from the said side of the inner part (1722a) and a second part (1723b) bending from the first part (1723a). The portion between the first part (1723a) and the second part (1723b) may be adjacent to the second pin (171Q). The second part (1723b) may be located between the second pin (171Q) and the third pin (171S), and may be located on the side of the third pin (171S). The supporter (1723) can have elasticity.

[0150] The elastic member (173) may be located between the inner part (1722a) and the second part (1723b). The elastic member (173) may be adjacent to the end of the second part (1723b). The elastic member (173) may be opposite to the third pin (171S) with respect to the second part (1723b). The first insertion pin (1722P) may protrude from the inner part (1722a) and may be inserted into one end of the elastic member (173). The second insertion pin (1723P) may protrude from the second part (1723b) and may be inserted into the other end of the elastic member (173). The imaginary line connecting the first insertion pin (1722P) and the second insertion pin (1723P) may be inclined to a vertical line parallel to the longitudinal axis of the movable body (172). The elastic member (173) may have elasticity. The elastic member (173) may be a coil spring.

[0151] Accordingly, when the movable body (172) is moved so that the inner parts (1721a, 1722a) move away from the ribs (1711, 1712), the supporter (1723) and the elastic member (173) can be elastically deformed. At this time, the length of the elastic member (173) can be shortened. When the external force applied to the movable body (172) is released, the movable body (172) can be moved so that the inner parts (1721a, 1722a) move closer to the ribs (1711, 1712) by the restoring force of the supporter (1723) and the elastic member (173).

[0152]

[0153] Referring to FIG. 27 together with FIG. 25, the hooks (180Ub) of the upper latches (180U) of the back cover (18) can be engaged with the engaging portions (1721b, 1722b). To facilitate the engagement of the hooks (180Ub) and the engaging portions (1721b, 1722b), the rear surface of the engaging portions (1721b, 1722b) may be sloped and may be referred to as a chamfer portion. The hooks (180Ub) can push against the chamfer portion and be engaged with the engaging portions (1721b, 1722b) which have returned to their original position by the restoring force of the elastic member (173). Upper latches (180U) can be positioned between the hooks (180Ub) and the ribs (1711, 1721). The ribs (1711, 1721) can restrict the upward movement of the upper latches (180U) engaged with the catches (1721b, 1722b).

[0154] Accordingly, the upper latches (180U) of the back cover (18) can be coupled to the upper holders (17U). Likewise, the lower latches (180L, see FIG. 24) of the back cover (18) can be coupled to the lower holders (17L, see FIG. 25). The holders (17) can prevent the back cover (18) from being pressed toward the plate (12). This prevents the top grill (30) and bottom grill (40) from being crushed by the back cover (18).

[0155] The user can insert a tool such as a steel ruler into the gap between the fins (32) of the top grill (30) and press the outer part (1721c) toward the first rib (1711) with the tool. In this case, the connection between the hooks (180Ub) and the locking parts (1721b, 1722b) can be released, and the user can detach the back cover (18) from the holder (17).

[0156] When the back cover (18) is coupled to the plate (12) through the holders (17), the upper side of the back cover (18) may be adjacent to the top grill (30), and the lower side of the back cover (18) may be adjacent to the bottom grill (40). Additionally, the left side of the back cover (18) may be located on the first side frame (161), and the right side of the back cover (18) may be located on the second side frame (162).

[0157] The upper latches (180U) and lower latches (180L) coupled to the upper holders (17U) and lower holders (17L) located to the left of the vertical line (VV') can be moved to the right along the locking parts (1721b, 1722b) as the curvature of the display (10) increases. The upper latches (180U) and lower latches (180L) coupled to the upper holders (17U) and lower holders (17L) located to the left of the vertical line (VV') can be moved to the left along the locking parts (1721b, 1722b) as the curvature of the display (10) decreases.

[0158] The upper latches (180U) and lower latches (180L) coupled to the upper holders (17U) and lower holders (17L) located to the right of the vertical line (VV') can be moved to the left along the locking parts (1721b, 1722b) as the curvature of the display (10) increases. The upper latches (180U) and lower latches (180L) coupled to the upper holders (17U) and lower holders (17L) located to the left of the vertical line (VV') can be moved to the right along the locking parts (1721b, 1722b) as the curvature of the display (10) decreases.

[0159] Accordingly, in response to a change in the curvature of the display (10), the latches (180) can be slid relative to the holders (17). The back cover (18) can be bent or straightened together with the display panel (11) and the plate (12). Regardless of the change in the curvature of the display (10), the gap between the back cover (18) and the plate (12) can be maintained constant.

[0160] As the curvature of the display panel (10) increases, the left side of the back cover (18) may move further away from the left side of the first side frame (161), and the right side of the back cover (18) may move further away from the right side of the second side frame (162). As the curvature of the display panel (10) decreases, the left side of the back cover (18) may move closer to the left side of the first side frame (161), and the right side of the back cover (18) may move closer to the right side of the second side frame (162). That is, the left and right sides of the back cover (18) may slip on the side frames (161, 162).

[0161] The top grille (30) and the bottom grille (40) may have elasticity. In response to the change in curvature of the display (10), the curvature of the body (31) of the top grille (30) and the body (411, 421) of the bottom grille (40) may also change. The bodies (31, 411, 421) may be bent convexly backward together with the plate (12), in which case the gap between the pins (32, 412, 422) may increase. The bodies (31, 411, 421) may be flattened together with the plate (12), in which case the gap between the pins (32, 412, 422) may return to the original gap.

[0162] Meanwhile, the guide panel (11S) may extend along the edge of the display panel (11). The guide panel (11S) may include a horizontal portion (11SH) and a vertical portion (11SV). The horizontal portion (11SH) may be located between the display panel (11) and the plate (12). The vertical portion (11SV) may intersect the horizontal portion (11SH) and may cover the edge of the display panel (11).

[0163]

[0164] Referring to FIGS. 28 and 29, the bracket (180M) may be fixed to the inside of the back cover (18) by a fastening member (Fm), such as a screw. Upper latches (180U) may be formed on the bracket (180M). Likewise, lower latches (180L, see FIG. 24) may also be formed on the bracket fixed to the inside of the back cover (18).

[0165] As described above, the hooks (180Ub) of the upper latches (180U) can be detachably coupled to the locking parts (1721b, 1722b). Likewise, the lower latches (180L, see FIG. 24) can also be detachably coupled to the locking parts (1721b, 1722b).

[0166] The user can insert a tool (H), such as a steel ruler, into the gap between the fins (32) of the top grill (30) and press the outer part (1721c) toward the first rib (1711) with the tool. In this case, the connection between the hooks (180Ub) and the locking parts (1721b, 1722b) can be released, and the user can detach the back cover (18) from the upper holder (17U). Likewise, the user can detach the back cover (18) from the lower holder (17L).

[0167]

[0168] Referring to FIG. 30, a plurality of holders (17') may be coupled to the rear of the plate (12). The holders (17') may be referred to as sliding latches (17'). The plurality of holders (17') may include upper holders (17U') arranged along the upper edge of the plate (12) and lower holders (17L') arranged along the lower edge of the plate (12). The upper holders (17U') and lower holders (17L') may be symmetrical vertically. That is, the description of the upper holder (17U') may be applied to the lower holder (17L'). Also, the description of the lower holder (17L') may be applied to the upper holder (17U'). The upper holder (17U') can be referred to as the first holder (17U'), and the lower holder (17L') can be referred to as the second holder (17L').

[0169] For example, among the total of six upper holders (17U'), three upper holders (17U') can be positioned between the first side frame (161) and the vertical line (VV') and between the first arm (151) and the top grille (30). The remaining three upper holders (17U') can be positioned between the vertical line (VV') and the second side frame (162) and between the second arm (152) and the top grille (30).

[0170] For example, among the total of six lower holders (17L'), three lower holders (17L') may be positioned between the first side frame (161) and the vertical line (VV') and between the first arm (151) and the first bottom grill (41). The remaining three lower holders (17L') may be positioned between the vertical line (VV') and the second side frame (162) and between the second arm (152) and the second bottom grill (42).

[0171] A portion of the first side holders (17T') may be adjacent to the first side frame (161), and the remainder may be adjacent to the second side frame (162). The first side holders (17T') may be aligned with the upper holder (17U').

[0172] A portion of the second side holders (17B') may be adjacent to the first side frame (161), and the remainder may be adjacent to the second side frame (162). The second side holders (17B') may be aligned with the lower holder (17L'). The second side holders (17B') may be vertically symmetrical with respect to the first side holders (17T').

[0173]

[0174] Referring to FIGS. 31 and 32, the holder (17') may include a fixed body (171', fixed body) and a moving body (172', moving body).

[0175] The fixed body (171') can be fixed on the rear surface of the plate (12). The fixed body (171') can have a box shape overall.

[0176] The movable body (172') can be coupled to the fixed body (171') so as to be movable in a vertical direction. The insertion portion (172a') of the movable body (172') can be inserted into the fixed body (171'). The catch portion (172b') of the movable body (172') can be formed in the insertion portion (172a') and can face the top grill (30) or the bottom grill (40).

[0177] The elastic member (173') may be positioned between the fixed body (171') and the movable body (172'). A fixed pin (171P') may protrude from the fixed body (171') and be inserted into one end of the elastic member (173'). A moving pin (172P') may protrude from the movable body (172') and be inserted into the other end of the elastic member (173'). The elastic member (173') may have elasticity. The elastic member (173') may be a coil spring.

[0178] Accordingly, when the movable body (172') is moved away from the top grill (30) or bottom grill (40), the elastic member (173') can be elastically deformed. At this time, the length of the elastic member (173') can be shortened. When the external force applied to the movable body (172') is released, the movable body (172') can be moved closer to the top grill (30) or bottom grill (40) by the restoring force of the elastic member (173'). Meanwhile, the extension part (174') can be extended from the fixed body (171').

[0179] The first side holder (17T') may include a fixed body (174'') and a locking part (172b''). The fixed body (174'') may be fixed on the rear surface of the plate (12). The fixed body (174'') may have a box shape overall. The locking part (172b'') may protrude from or be formed from the fixed body (174''). Likewise, the second side holder (17B', see FIG. 30) may also have a fixed body and a locking part.

[0180] The hook (180Ub) of the upper latch (180U) of the back cover (18) can be engaged with the catch portion (172b'). To facilitate the connection between the hook (180Ub) and the catch portion (172b'), the rear surface of the catch portion (172b') may be sloped and may be referred to as a chamfer portion. The hook (180Ub) can push the chamfer portion and be engaged with the catch portion (172b') which returns to its original position by the restoring force of the elastic member (173'). The hook (180Ub) of the other upper latch (180U) of the back cover (18) can be engaged with the catch portion (172b'') of the first side holder (17T').

[0181] Accordingly, the upper latches (180U) of the back cover (18) can be coupled to the upper holders (17U') and the first side holders (17T'). Likewise, the lower latches (180L, see FIG. 24) of the back cover (18) can be coupled to the lower holders (17L') and the second side holders (17B', see FIG. 30). The holders (17') can prevent the back cover (18) from being pressed toward the plate (12). This prevents the top grill (30) and the bottom grill (40) from being crushed by the back cover (18).

[0182] The user can insert a tool such as a steel ruler into the gap between the pins (32, fins) of the top grill (30) and press the moving body (172') with the tool. In this case, the connection between the hook (180Ub) and the locking part (172b') can be released, and the user can detach the back cover (18) from the holder (17').

[0183] When the back cover (18) is coupled to the plate (12) through the holders (17'), the upper side of the back cover (18) may be adjacent to the top grill (30), and the lower side of the back cover (18) may be adjacent to the bottom grill (40). Additionally, the left side of the back cover (18) may be located on the first side frame (161), and the right side of the back cover (18) may be located on the second side frame (162).

[0184] The upper latches (180U) and lower latches (180L) coupled to the upper holders (17U'), lower holders (17L'), and side holders (17T', 17B') located to the left of the vertical line (VV') can be moved to the right along the locking parts (172b', 172b'') as the curvature of the display (10) increases. The upper latches (180U) and lower latches (180L) coupled to the upper holders (17U'), lower holders (17L'), and side holders (17T', 17B') located to the left of the vertical line (VV') can be moved to the left along the locking parts (172b', 172b'') as the curvature of the display (10) decreases.

[0185] The upper latches (180U) and lower latches (180L) coupled to the upper holders (17U'), lower holders (17L'), and side holders (17T', 17B') located to the right of the vertical line (VV') can be moved to the left along the locking parts (172b', 172b'') as the curvature of the display (10) increases. The upper latches (180U) and lower latches (180L) coupled to the upper holders (17U'), lower holders (17L'), and side holders (17T', 17B') located to the left of the vertical line (VV') can be moved to the right along the locking parts (172b', 172b'') as the curvature of the display (10) decreases.

[0186] Accordingly, in response to a change in the curvature of the display (10), the latches (180) can be slid relative to the holders (17'). The back cover (18) can be bent or straightened together with the display panel (11) and the plate (12). Regardless of the change in the curvature of the display (10), the gap between the back cover (18) and the plate (12) can be maintained constant.

[0187] As the curvature of the display panel (10) increases, the left side of the back cover (18) may move further away from the left side of the first side frame (161), and the right side of the back cover (18) may move further away from the right side of the second side frame (162). As the curvature of the display panel (10) decreases, the left side of the back cover (18) may move closer to the left side of the first side frame (161), and the right side of the back cover (18) may move closer to the right side of the second side frame (162). That is, the left and right sides of the back cover (18) may slip on the side frames (161, 162).

[0188] The top grille (30) and the bottom grille (40) may have elasticity. In response to the change in curvature of the display (10), the curvature of the body (31) of the top grille (30) and the body (411, 421) of the bottom grille (40) may also change. The bodies (31, 411, 421) may be bent convexly backward together with the plate (12), in which case the gap between the pins (32, 412, 422) may increase. The bodies (31, 411, 421) may be flattened together with the plate (12), in which case the gap between the pins (32, 412, 422) may return to the original gap.

[0189]

[0190] Referring to FIG. 33, the bracket (18M) may be fixed to the outside of the back cover (18) by a fastening member such as a screw. A portion of the bracket (18M) may penetrate the back cover (18), and upper latches (180U) may be formed on said portion of the bracket (180M). Likewise, lower latches (180L, see FIG. 24) may also be formed on the bracket fixed to the outside of the back cover (18).

[0191]

[0192] Referring to FIG. 34, a holder (17'') may be provided in place of the holder (17') described above with reference to FIG. 31 and 32. The holder (17'') may be referred to as a sliding latch (17''). The holder (17'') may include a fixed body (171'') and a moving body (172'').

[0193] The fixed body (171'') can be fixed on the rear surface of the plate (12, see FIG. 31). The fixed body (171'') can have a box shape overall.

[0194] The movable body (172'') can be coupled to the fixed body (171'') so as to be movable in a vertical direction. The insertion portion (172a'') of the movable body (172'') can be inserted into the fixed body (171''). The catch portion (172b'') of the movable body (172'') can be formed in the insertion portion (172a'') and can face the top grill (30) or the bottom grill (40).

[0195] The elastic member (173'') may be positioned between the fixed body (171'') and the movable body (172''). The fixed pin (171P'') may protrude from the fixed body (171'), and the elastic member (173') may be fixed to the fixed pin (171P''). The elastic member (173'') may have elasticity. The elastic member (173'') may be a clip-shaped spring fitted onto the fixed pin (171P''). One side of the elastic member (173'') may support the movable body (172'').

[0196] Accordingly, when the movable body (172'') is moved away from the top grill (30) or bottom grill (40), the elastic member (173'') can be elastically deformed. At this time, the elastic member (173') can be compressed. When the external force applied to the movable body (172'') is released, the movable body (172'') can be moved closer to the top grill (30) or bottom grill (40) by the restoring force of the elastic member (173''). Meanwhile, the extension part (174'') can be extended from the fixed body (171'').

[0197] By engaging the hook (180Ub) of the upper latch (180U) with the catch (172b''), the back cover (18) can be attached to the holder (17'').
