[0092] The first wing 143 may be pivotally connected to the first wing bracket 131. The second wing 141 may be pivotally connected to the second wing bracket 132. The first wing 143 and the second wing 141 may be line symmetrical with respect to the driving module 130. The description of the first wing 143 and the first wing bracket 131 may also apply to the second wing 141 and the second wing bracket 132 (and vice versa). The first wing 143 may include a wing plate 1431, a pivot PH, and a rod 1435.

[0093] The wing plates 1411 and 1431 may be long plates. The rods 1415 and 1435 may extend from one end of the wing plates 1411 and 1431. The rods 1415 and 1435 may be long plates. The length of the rods 1415 and 1435 may be less than the length of the wing plates 1411 and 1431, and the width of the rods 1415 and 1435 may be less than the width of the wing plates 1411 and 1431. The thickness of the wing plates 1411 and 1431 may be substantially equal to the thickness of the rods 1415 and 1435.

[0094] The pivot PH may be pivotally connected to a pin of the wing bracket 131, 132. The pin may be inserted into the pivot PH of the wing 141, 143. The wing 141, 143 may pivot on the wing bracket 131, 132 around the pin.

[0095] Reference Fig.16 and Fig.17 , the lead screw 133 may be rotatably mounted to the front bracket 130F. For example, the lead screw 133 may be elongated and may have threads on its outer surface. The lead screw 133 may be inserted into the slider 134a. The slider 134a and the lead screw 133 may be coupled to each other by threads. When the lead screw 133 rotates, the slider 134a may reciprocate in the longitudinal direction of the lead screw 133.

[0096] The slider guide 134b may be fixed to the slider 134a. The slider guide 134b may move together with the slider 134a. The guide shafts 135a, 135b may be coupled or fixed to the front bracket 130F. The guide shafts 135a, 135b may be parallel to the lead screw 133. The guide shafts 135a, 135b may include a first guide shaft 135a and a second guide shaft 135b. The first guide shaft 135a may be arranged opposite to the second guide shaft 135b with respect to the lead screw 133. The guide shafts 135a, 135b may be inserted into the slider guide 134b. Therefore, when the lead screw 133 rotates, the slider 134a may reciprocate in the longitudinal direction of the lead screw 133 in a stable manner.

[0097] The motor 136 may be mounted on the base 130B. The motor 136 may be an electric motor. The motor 136 may be a stepping motor. The motor 136 may control the number of steps corresponding to the rotation angle, the rotation direction and the rotation speed. The rotation axis 136a of the motor 136 may intersect with the longitudinal direction of the lead screw 133. The motor 136 and the rotation axis 136a of the motor 136 may be arranged between the lead screw 133 and the base 130B. The worm 137d may be fixed to the rotation axis 136a of the motor 136 and may rotate with the rotation axis 136a of the motor 136. The worm wheel 137a may mesh with the worm wheel 137d. The transmission gear 137b may rotate coaxially with the worm wheel 137a. The drive gear 137c may be fixed to one end of the lead screw 133 to rotate with the lead screw 133. The drive gear 137c may mesh with the transmission gear 137b. The diameter of the driving gear 137c may be greater than the diameter of the transmission gear 137b.

[0098] Reference Fig.18 The disk indicator 136b may be adjacent to the distal end of the rotating shaft 136a of the motor 136 and may be fixed to the rotating shaft 136a. The disk indicator 136b may include a plurality of holes (without reference numerals) spaced apart from each other in a circumferential direction of the disk indicator 136b.

[0099] The counting sensor 136c may be adjacent to the disk indicator 136b and may be fixed to the base 130B or the second wing bracket 132. The counting sensor 136c may be a photoelectric sensor. The counting sensor 136c may be horseshoe-shaped. The light emitting portion and the light receiving portion of the counting sensor 136c may be spaced apart from each other while being opposite to each other. When the rotating shaft 136a rotates, the disk indicator 136b may rotate while passing between the light emitting portion and the light receiving portion of the counting sensor 136c. In response to the rotation of the disk indicator 136b, the light of the light emitting portion of the counting sensor 136c may pass through the hole of the disk indicator 136b, or may be blocked by the disk indicator 136b.

[0100] Therefore, the counting sensor 136 c may detect the number of revolutions and / or the amount of rotation of the motor 136 .

[0101] The mounting seat 130M may be adjacent to the outer circumference of the driving gear 137c and may be fixed to the rear bracket 130R. The extensions 130M1 and 130M2 may extend from the mounting seat 130M in a direction parallel to the lead screw 133. The extensions 130M1 and 130M2 may be provided on the upper side of the slider 134a or the upper side of the slider guide 134b.

[0102] Pin indicator 138a (see Fig.17 ) may be fixed to the slider 134a or the slider guide 134b. The pin indicator 138a may be pin-shaped.

[0103] The first sensor 138b may be coupled to the extension portion 130M1. Alternatively, the first sensor 138b may be coupled to the front bracket 130F. The first sensor 138b may be a photoelectric sensor. The first sensor 138b may be horseshoe-shaped. The light emitting portion and the light receiving portion of the first sensor 138b may be spaced apart from each other while being opposite to each other. As the slider 134a performs a linear reciprocating motion, the pin indicator 138a may pass between the light emitting portion and the light receiving portion of the first sensor 138b. In response to the movement of the pin indicator 138a, the light of the light emitting portion of the first sensor 138b may be provided to the light receiving portion of the first sensor 138b, or may be blocked by the pin indicator 138a.

[0104] Thus, the first sensor 138b can detect the approach of the pin indicator 138a. When the slider 134a is positioned closer to the front bracket 130F, the first sensor 138b can detect the pin indicator 138a (see Fig.19 and Fig. 20 ). At this time, as will be referred to later Figure 21 to Figure 23 As described, the board 120 and the display panel 110 coupled to the slider 134a through the wings 141, 143 and the side frames 151, 153 may have a minimum curvature, and this position may be referred to as a starting point of the slider 134a. For example, the minimum curvature may be "zero (0)", and therefore, the display panel 110 may be flat.

[0105] The second sensor 139b may be spaced apart from and located behind the first sensor 138b, and may be coupled to the extension portion 130M1. Alternatively, the second sensor 139b may be coupled to the rear bracket 130R. The second sensor 139b may be a photoelectric sensor. The second sensor 139b may be horseshoe-shaped. The light emitting portion and the light receiving portion of the second sensor 139b may be spaced apart from each other while being opposite to each other. As the slider 134a performs a linear reciprocating motion, the pin indicator 138a may pass between the light emitting portion and the light receiving portion of the second sensor 139b. In response to the movement of the pin indicator 138a, the light of the light emitting portion of the second sensor 139b may be provided to the light receiving portion of the second sensor 139b, or may be blocked by the pin indicator 138a.

[0106] Thus, the second sensor 139b can detect the approach of the pin indicator 138a. When the slider 134a is positioned closer to the rear bracket 130R, the second sensor 139b can detect the pin indicator 138a (see Fig.19 and Fig. 20 ). At this time, as will be referred to later Figure 21 to Figure 23As described, the board 120 and the display panel 110 coupled to the slider 134a through the wings 141, 143 and the side frames 151, 153 may have a maximum curvature, and this position may be referred to as the end point of the slider 134a. For example, the minimum curvature radius may be 1000 mm, 800 mm, or 700 mm.

[0107] The display device may include at least one of the counting sensor 136c, the first sensor 138b, and the second sensor 139b.

[0108] Reference Fig.19 and Fig. 20 , the wing 1411 may include a first portion 1411a, a second portion 1411b, and a third portion 1411c. The first portion 1411a may be disposed opposite to the rod 1415 relative to the pivot axis PH. The first portion 1411a may be bent at the rod 1415 and may form an obtuse angle relative to the rod 1415. The second portion 1411b may be bent at the first portion 1411a, may be substantially parallel to the rod 1415, and may form an obtuse angle relative to the first portion 1411a. The third portion 1411c may be bent at the second portion 1411b, may be substantially parallel to the first portion 1411a, and may form an obtuse angle relative to the second portion 1411b.

[0109] The second wing 141 may include a connecting rod 1416. The connecting rod 1416 may be fixed to the rod 1415 or extend from the rod 1415. The connecting rod 1416 may be connected to the slider 134a. The connecting rod 1416 may be pivotally connected to the slider 134a. The connecting rod 1416 may include an elongated hole LH. The elongated hole LH may be formed on a distal end of the connecting rod 1416 adjacent to the slider 134a. The slider 134a may include a connecting pin GP. The connecting pin GP may be cylindrical. The diameter of the connecting pin GP may be substantially the same as the width of the elongated hole LH.

[0110] When the lead screw 133 rotates, the slider 134a may reciprocate in the longitudinal direction of the lead screw 133. The rod 1415 connected to the slider 134a through the connecting rod 1416 may move together with the slider 134a, and the second wing 141 may pivot around the pivot PH. Here, the connecting pin GP may move in the long hole LH.

[0111] Reference Figure 21 to Figure 23 , side frames 151, 153 (see Fig.15 ) can be coupled or fixed to the rear portion or rear surface of the board 120. As a fastening member such as a screw passes through the first side frame 153 to be fastened to the corresponding plurality of side fixing portions 162P (see Fig.11 ), the first side frame 153 may be coupled to the board 120. As a fastening member such as a screw passes through the second side frame 151 to be fastened to a corresponding plurality of side fixing portions 162P (see FIG. 1 ) adjacent to the left side of the board 120. Fig.11 ), the second side frame 151 may be coupled to the plate 120.

[0112] The second side frame 151 may include a sliding mount 152. The sliding mount 152 may be mounted on the side frame 151 or fixed on the side frame 151.

[0113] The second wing 141 may be coupled to the slide mount 152 to be movable on the slide mount 152. As the second wing 141 moves on the slide mount 152, a distal end of the wing plate 1411 may contact the slide mount 152.

[0114] The sliding mount 152 may include a side wall 152W. The side wall 152W may face the side of the flap 1411. As the flap 1411 moves on the sliding mount 152, the flap 1411 may contact the side wall 152W. The side wall 152W may guide the movement of the flap 1411.

[0115] A guide groove 152S may be formed in the side wall 152W. The guide groove 152S may be formed through the side wall 152W in an elongated manner in a longitudinal direction of the wing plate 1411. For example, the guide groove 152S may be rectangular.

[0116] The end pin 1419 may be inserted into the guide slot 152S. The end pin 1419 may move on the guide slot 152S. The end pin 1419 together with the guide slot 152S may limit or restrict the movement of the wing plate 1411. For example, the end pin 1419 may have a rectangular cross section.

[0117] Therefore, the force transferred from the flap 1411 to the side frame 151 may be continuously maintained. In addition, as the display panel 110 and the board 120 are bent, expansion of regions adjacent to both ends of the display panel 110 and the board 120 may be reduced or prevented.

[0118] In response to the pivoting movement of the second wing 141, the second side frame 151 may push the board 120 forward or pull the board 120 backward at a position adjacent to the left side of the board 120. In response to the pivoting movement of the first wing 143, the first side frame 153 may push the board 120 forward or pull the board 120 backward at a position adjacent to the right side of the board 120. That is, the board 120 and the display panel 110 may bend when pushed by the side frames 151 and 153, or may be unfolded when pulled by the side frames 151 and 153.

[0119] In addition, the slide mount 152 may include a stopper 152a formed by bending its distal end. When the board 120 is kept flat, the distal end of the wing plate 1411 may contact the stopper 152a of the slide mount 152. Therefore, it is possible to prevent the front surface of the display panel 110 from being convexly or outwardly bent due to the two ends of the board 120 being toward the rear of the display device 100.

[0120] Reference Fig.24 , the first frame 171' is a reference Figure 4 , Figure 8 and Fig.28 The modified example of the first frame 171 described above. Figure 4 and Fig. 9 The described second frame 172 may also be modified like the first frame 171'. The first frame 171' may include a first vertical portion 171V' and first horizontal portions 171H1', 171H2'. The first horizontal portions 171H1', 171H2' may be referred to as first ribs 171H1', 171H2'.

[0121] The first vertical portion 171V' may define an upper side 170U of the frame 170'. The first vertical portion 171V' may define a length in the left-right direction, a width in the front-rear direction, and a thickness in the up-down direction.

The first rear horizontal portion 171H1' may be referred to as a first rear rib 171H1', and the first central horizontal portion 171H2' may be referred to as a first central rib 171H2'.

[0123] The upper side of the plate 120 may be inserted between the first rear horizontal portion 171H1 ′ and the first center horizontal portion 171H2 ′.

[0124] The inner plate 160 may be disposed opposite to the plate 120 with respect to the first central horizontal portion 171H2 ′.

[0125] Display panel 110 (see Fig. 27 ) may be disposed below the first vertical portion 171V'.

[0126] A plurality of protrusion portions 171V1 ′ and 171V2 ′ may be formed at an inner side of the first vertical portion 171V′, and may be disposed in front of the first center horizontal portion 171H2 ′.

[0127] Reference Fig.25 , the third frame 173' is a reference Figure 5 , Fig.10 and Fig.29 A modified example of the third frame 173 described above. Figure 5 The fourth frame 174 described may also be modified like the third frame 173'. The third frame 173' may include a third vertical portion 173V' and third horizontal portions 173H1', 173H2', 173H3'. The third horizontal portions 173H1', 173H2', 173H3' may be referred to as third ribs 173H1', 173H2', 173H3'.

[0128] The third vertical portion 173V' may define the left side 170L of the frame 170'. The length of the third vertical portion 173V' may be defined in the up-down direction, the width of the third vertical portion 173V' may be defined in the front-rear direction, and the thickness of the third vertical portion 173V' may be defined in the left-right direction.

[0129] The third horizontal portions 173H1', 173H2', 173H3' may protrude from the inner side of the third vertical portion 173V' in a direction intersecting the third vertical portion 173V'. The third rear horizontal portion 173H1' may protrude rightward from the rear end of the third vertical portion 173V', and may extend in the longitudinal direction of the third vertical portion 173V'. The third center horizontal portion 173H2' may protrude rightward between the rear end and the front end of the third vertical portion 173V', and may extend in the longitudinal direction of the third vertical portion 173V'. With respect to the third center horizontal portion 173H2', the third front horizontal portion 173H3' may be disposed opposite to the third rear horizontal portion 173H1', may protrude rightward from the inner side of the third vertical portion 173V', and may extend in the longitudinal direction of the third vertical portion 173V'. The third rear horizontal portion 173H1' may be referred to as a third rear rib 173H1', the third center horizontal portion 173H2' may be referred to as a third center rib 173H2', and the third front horizontal portion 173H3' may be referred to as a third front rib 173H3'.

[0130] The left side of the plate 120 may be inserted between the third rear horizontal portion 173H1 ′ and the third center horizontal portion 173H2 ′.

[0131] The left side of the inner panel 160 may be inserted between the third center horizontal portion 173H2 ′ and the third front horizontal portion 173H3 ′.

[0132] With respect to the third front horizontal portion 173H3', the display panel 110 may be disposed opposite to the inner panel 160. The display panel 110 may be disposed on the right side of the third vertical portion 173V'.

[0133] Reference Fig.26 and Fig. 27 , by cutting off a portion of the left end of the first vertical portion 171V' and the first rear horizontal portion 171H1' (see Fig.24 ) to form the first cutout 171Va'. Here, the third rear horizontal portion 173H1' may be disposed at the first cutout 171Va', and the third center horizontal portion 173H2' and the third front horizontal portion 173H3' may be disposed below the first vertical portion 171V'. In addition, the first cutout 171Va' may have a shape corresponding to the third rear horizontal portion 173H1', and may guide the movement of the third horizontal portion 173H1'.

[0134] The center line Cp of the side fixing portion 162P may be positioned rightward relative to the left end of the third vertical portion 173V' and the first vertical portion 171V'. The side fixing portion 162P may be positioned rightward relative to the first cutout 171Va'. Here, the second side frame 151 (see Fig. 20 ) can be fixed to the side fixing portion 162P.

[0135] In addition, the third frame 173 ′ may be fixed to the display panel 110 , and the first frame 171 ′ may be fixed to the inner plate 160 disposed at the rear of the display panel 110 .

[0136] Therefore, when the second side frame 151 (see Fig. 20 ) pushes the side fixing portion 162P forward, the display panel 110 may be bent at a greater curvature than the inner plate 160 and the first frame 171', and the third frame 173' may slide relative to the inner plate 160 and the first frame 171'. In other words, when the second side frame 151 (see Fig. 20 ) pushes the side fixing portion 162P forward, the third frame 173' may be away from the first frame 171', thereby achieving bending of the display panel 110. Since a gap between the third frame 173' and the first frame 171' is formed on the left side (outside) of the side fixing portion 162P, the third frame 173' may be away from the first frame 171' in a straight line.

[0137] Here, in the gap between the third frame 173' and the first frame 171', the third rear horizontal portion 173H1' may cover the rear of the third center horizontal portion 173H2' and the rear of the third front horizontal portion 173H3'. In addition, the upper surface of the first vertical portion 171V', the upper end of the third rear horizontal portion 173H1', and the upper end of the third vertical portion 173V' may be located on the same straight line. That is, although the third center horizontal portion 173H2' and the third front horizontal portion 173H3' are located at a lower position than the third vertical portion 173V', for a user viewing the front surface of the display device 100, due to the third rear horizontal portion 173H1', the first vertical portion 171V' and the third vertical portion 173V' may be considered or regarded as continuous without a step.

[0138] The third rear horizontal portion 173H1' may be referred to as a gap cover 173H1'. For example, when the curvature of the display panel 110 is zero (0), the gap between the third frame 173' and the first frame 171' may be about 0.2 mm. For example, when the curvature radius of the display panel 110 is 900 mm, the gap between the third frame 173' and the first frame 171' may be about 1.9 mm.

[0139] Reference Fig.28 , the first frame 171 may include a first vertical portion 171V and first horizontal portions 171H1, 171H2. The description of the first frame 171 may also be applied to the second frame 172 (see Figure 4 ). The first horizontal portions 171H1, 171H2 may be referred to as first ribs 171H1, 171H2.

[0144] Display panel 110 (see Fig.32 ) may be disposed below the first vertical portion 171V.

[0145] The guide groove 171a may be formed inside the first vertical portion 171V and may be disposed between the first rear horizontal portion 171H1 and the first protruding portion 171V1. The left guide groove 171a may be formed rightward from the left end of the first vertical portion 171V, and the right guide groove (not shown) may be formed leftward from the right end of the first vertical portion 171V.

[0146] Reference Fig.29 The third frame 173 may include a third vertical portion 173V and third horizontal portions 173H1, 173H2, 173H3. The description of the third frame 173 may also be applied to the fourth frame 174 (see Figure 5 ). The third horizontal portions 173H1, 173H2, 173H3 may be referred to as third ribs 173H1, 173H2, 173H3.

[0148] The third horizontal portions 171H1, 173H2, 173H3 may protrude from the inner side of the third vertical portion 173V in a direction intersecting the third vertical portion 173V. The upper ends of the third horizontal portions 173H1, 173H2, 173H3 may be located at a lower position than the upper end of the third vertical portion 173V.

The third rear horizontal portion 173H1 may be referred to as a third rear rib 173H1 , the third center horizontal portion 173H2 may be referred to as a third center rib 173H2 , and the third front horizontal portion 173H3 may be referred to as a third front rib 173H3 .

[0149] The left side of the plate 120 may be inserted between the third rear horizontal portion 173H1 and the third center horizontal portion 173H2.

[0150] The left side of the inner panel 160 may be inserted between the third center horizontal portion 173H2 and the third front horizontal portion 173H3.

[0151] With respect to the third front horizontal portion 173H3, the display panel 110 may be disposed opposite to the inner panel 160. The display panel 110 may be disposed on the right side of the third vertical portion 173V.

[0152] In addition, a gap cover 175 may be provided on the third central horizontal portion 173H2 and the third front horizontal portion 173H3. For example, the gap cover 175 may be coupled to the third central horizontal portion 173H2 and the third front horizontal portion 173H3, and may be in contact with the inner side of the third vertical portion 173V. In another example, the gap cover 175 may be coupled to the inner side of the third vertical portion 173V, and may be in contact with the third horizontal portion 173H2 and the third front horizontal portion 173H3. In another example, the gap cover 175 may be coupled to the inner side of the third central horizontal portion 173H2, the third front horizontal portion 173H3, and the third vertical portion 173V.

[0153] The gap cover 175 may be coupled to the third center horizontal portion 173H2, the third front horizontal portion 173H3, and / or the third vertical portion 173V in an interference fit manner or by bonding using a double-sided tape. Alternatively, the gap cover 175 may be integrally formed with the third horizontal portions 173H2, 173H3, and / or the third vertical portion 173V.

[0154] The left gap cover 175 may be coupled to the inner side of the third frame 173, and the right gap cover (not shown) may be coupled to the inner side of the fourth frame 174 (see FIG. Figure 5 ).

[0155] The gap cover 175 may include a first leg 1751, a second leg 1752, and a cover 1753. The first leg 1751 may protrude upward from the third center horizontal portion 173H2. The second leg 1752 may protrude upward from the third front horizontal portion 173H3. The cover 1753 may be disposed on the first leg 1751 and the second leg 1752, and may be integrally formed with the first leg 1751 and the second leg 1752. The cover 1753 may be spaced downward from the upper end of the third vertical portion 173V, and may be formed in a flat shape.

[0156] For example, the gap cover 175 may include a metal material such as aluminum (Al). In another example, the gap cover 175 may include a plastic or resin material.

[0157] Reference Fig.30 , the shape of the cover 1753 may correspond to the guide groove 171a. The cover 1753 may be inserted into the guide groove 171a. Therefore, the guide groove 171a may guide the connection or movement of the cover 1753.

[0158] Reference Fig.31 and Fig.32 , the third rear horizontal portion 173H1 may be disposed under the first rear horizontal portion 171H1 , and the gap cover 175 may be disposed under the first vertical portion 171V.

[0159] The center line Cp of the side fixing portion 162P may be positioned rightward relative to the left end of the third vertical portion 173V and the first vertical portion 171V. The side fixing portion 162P may be positioned rightward relative to the left end of the first vertical portion 171V. Here, the second side frame 151 (see Fig. 20 ) can be fixed to the side fixing portion 162P.

[0160] In addition, the third frame 173 may be fixed to the display panel 110 , and the first frame 171 may be fixed to the inner plate 160 disposed at the rear of the display panel 110 .

[0161] Therefore, when the second side frame 151 (see Fig. 20) pushes the side fixing portion 162P forward, the display panel 110 may be bent with a curvature greater than that of the inner plate 160 and the first frame 171, and the third frame 173 may slide relative to the inner plate 160 and the first frame 171. In other words, when the second side frame 151 (see Fig. 20 ) pushes the side fixing portion 162P forward, the third frame 173 can be away from the first frame 171, thereby realizing the bending of the display panel 110. Since a gap between the third frame 173 and the first frame 171 is formed on the left side (outside) of the side fixing portion 162P, the third frame 173 can be away from the first frame 171 in a straight line.

[0162] Here, the cover portion 1753 of the gap cover 175 may cover the upper sides of the third center horizontal portion 173H2 and the third front horizontal portion 73H3 in the gap between the third frame 173 and the first frame 171. Since the cover portion 1753 is disposed at the guide groove 171a, a step between an upper surface of the cover portion 1753 and an upper surface of the first vertical portion 171V and a step between an upper surface of the cover portion 1753 and an upper end of the third vertical portion 173V may be minimized.

[0163] For example, when the curvature of the display panel 110 is zero (0), the gap between the third frame 173 and the first frame 171 may be about 0.2 mm. For example, when the curvature radius of the display panel 110 is 900 mm, the gap between the third frame 173 and the first frame 171 may be about 1.9 mm.
