Description

Technical Field

[0001] The present invention relates to a deformable display device, and more particularly, to a display device that changes position and is introduced or led out when needed. Background Art

[0002] Vehicles include various input units and output units as devices for user interfaces. In the prior art, the input units are mainly mechanical input units such as buttons, knobs, and levers. However, in recent years, there is an increasing trend of vehicles using input units that allow users to input more intuitively, ranging from voice input units, touch input units to gesture input units.

[0003] As an output unit, the most basic output unit is a cluster including an instrument panel that provides information about the vehicle's speed, RPM, fuel level, etc., but as display technology improves and vehicle functions become more precise and diverse, vehicles including display units for outputting various contents are increasing.

[0004] In the prior art, a small LCD screen for outputting sound was all that was needed, but in recent years, a large display unit for displaying navigation and vehicle status has been applied to the center instrument panel between the driver's seat and the front passenger seat. In addition, the cluster of the instrument panel can also provide various information by applying a non-pin-type display.

[0005] In addition, in order to allow users to see important information without diverting their eyes, HUD (head up display) output on the front windshield has become popular, so that the driver can check the speed or navigation guidance while looking forward.

[0006] The display not only simply outputs information but also has a touch sensor and enables touch input at the same time, thereby being able to function as both an output unit and an input unit. Therefore, the size of the display used in the vehicle tends to be larger.

[0007] However, since the dial including the instrument panel and the center instrument panel is located at the front of the vehicle, there is a problem of blocking the front view when the size of the panel is increased. In addition, in recent years, as the autonomous driving function becomes more advanced, there are also cases where the function of the dial panel that provides information to the user during autonomous driving is not required or reduced, so the size of the dial panel is not necessarily large. Summary of the invention

[0059] Figure 1 is a front perspective view showing a first state of the display device 10 according to the embodiment of the present invention, Figure 2 1 is a front perspective view showing a second state of the display device 10 according to the embodiment of the present invention.

[0060] In the case of realizing a large screen in a limited space, the display device 10 of the present invention can be used. The display device 10 of the present invention can be changed in position as needed, so as to be set in a position where space utilization can be improved. For example, the display device 10 of the present invention can be used as a dial panel located on the front of a vehicle.

[0061] The display device 10 of the present invention can be Figure 1 The first state transitions to Figure 2 When switching from the first state to the second state, the display portion 100 may switch to the second state while moving downward. Figure 2 The state of bending deformation is shown.

[0062] The display unit 100 may include a display panel on the front side thereof and a rear structure on the rear side thereof covering the display unit 100. The display device 10 may include a fixing unit 310 for fixing the display device 10 to a vehicle or a specific place, and a driving unit 330 and a moving unit attached to the rear structure of the display unit 100 to change the position and shape of the display unit 100.

[0063] The display panel can display graphic objects corresponding to various information. The display panel may include at least one of a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display (flexible display), a three-dimensional display (3D display), and an electronic ink display (e-ink display). The display panel may form a stacked structure or an integrated structure with the touch input unit 213 to realize a touch screen.

[0064] In order to achieve Figure 2 The bending deformation shown in FIG. 1 can use a flexible display such as an organic light-emitting diode (OLED). Even if a flexible display panel is used, it is difficult to maintain rigidity when all regions are bent and deformed. Figure 2 As shown, a portion of the section is a variable portion B that undergoes bending deformation, and the variable portion B may include flat portions F1 and F2 on the upper and lower sides.

[0065] When the overall curvature of the display unit 100 changes, it is difficult to achieve Figure 2 The combination of the moving units 320 and 340 is shown for deformation and position change of the display portion 100. In addition, due to the flexible structure, the degree of freedom of shape change increases, so there is a possibility of deformation into an unexpected form.

[0066] The upper plane portion F1 moves only in the vertical direction with respect to the variable portion B, and the lower plane portion F2 moves downward while obliquely protruding forward. The upper plane portion F1 and the lower plane portion F2 move in different directions, so the curvature of the variable portion B between the upper plane portion F1 and the lower plane portion F2 changes.

[0067] Figure 3 is a rear perspective view showing a first state of the display device 10 according to the embodiment of the present invention, Figure 4 1 is a rear view showing a first state of the display device 10 according to the embodiment of the present invention.

[0068] A structure for changing the position and shape of the display unit 100 and for installation is provided on the back side of the display unit 100 of the display device 10 of the present invention.

[0069] The structure may mainly include a fixing unit 310, a moving unit and a driving unit 330. The fixing unit 310 is a component for fixing the display device 10 to a vehicle or the like, and the driving unit 330 is located in the fixing unit 310 and provides power to move the moving unit relative to the fixing unit 310.

[0070] The moving unit is a component that receives power from the driving unit 330 and moves, and is combined with the plane parts F1 and F2 of the display unit 100 to guide the movement and deformation of the display unit 100. The moving unit can be mainly composed of a linear moving unit 320 combined with the upper plane part F1 and a curved moving unit 340 combined with the lower plane part F2.

[0071] The fixed unit 310 may include a horizontal base 316 fixed to the bottom surface and a vertical base 311 extending vertically from the horizontal base 316. The vertical base 311 may be formed with rails 312, 314, 315 for sliding the moving units 320 and 340, and the moving units 320 and 340 may move relative to the vertical base 311 and change the position of the display unit 100.

[0072] like Figure 3 As shown, the vertical bases 311 can be arranged in pairs on the left and right, and correspondingly, the moving units 320 and 340 can also be arranged in pairs on the left and right. By the moving units 320 and 340 arranged in pairs on the left and right, the display unit 100 can be stably moved without shaking.

[0073] The moving unit may include a linear moving unit 320 for moving the upper plane portion F1 of the display unit 100 in a vertical direction, and a curved moving unit 340 for guiding the lower plane portion F2 of the display unit 100 to protrude forward and move when moving downward.

[0074] The linear moving unit 320 may move up and down along a linear track formed on the vertical base 311 , and the curved moving unit 340 may move along the curved track.

[0075] The vertical base 311 may include a linear track extending in a vertical direction, and may include: a first linear track 314, such as Figure 2 As shown in the front of the vertical base 311; and the second linear track 315, as Figure 3 The linear rails may be provided on only one side, but in order to support the weight of the display unit 100 and allow it to move without twisting, they may be provided in pairs at the front and rear.

[0076] The linear moving unit 320 may include a first guide block 324 moving along a first linear rail 314 formed at the vertical base 311 , and a second guide block 325 moving along the second linear rail 315 .

[0077] The first guide block 324 may be fastened to the first front bracket 322, and the second guide block 325 may be fastened to the rear bracket 323. In order to move the first guide block 324 and the second guide block 325 simultaneously, a moving plate 321 between the first front bracket 322 and the rear bracket 323 may be provided.

[0078] like Figure 3 As shown, the moving plate 321 may be located at an inner side of the pair of vertical bases 311 in a direction opposite to each other. The moving plate 321 may be configured to form a predetermined interval with the vertical base 311.

[0079] Figure 5 3 is a top view of the moving unit of the display device 10 according to an embodiment of the present invention. The moving plate 321 is not directly combined with the linear rails 314 and 315, but is combined using the first front bracket 322 and the rear bracket 323, and a space can be formed between the moving plate 321 and the vertical base 311.

[0080] like Figure 5 As shown, the curve moving unit 340 may be located between the vertical base 311 and the moving plate 321. The curve moving unit 340 may include a lower arm 341, the lower portion of which is coupled to the back of the lower flat surface portion F2 and extends upward. The lower portion of the lower arm 341 is connected to the lower surface of the lower flat surface portion F2 by a second front bracket 345 ( Figure 3 ) is combined with the lower side plane portion F2.

[0081] The curve moving unit 340 may further include an upper arm 342 on an upper side of the lower arm 341. The upper arm 342 may include guide protrusions 343, 344 that move along the curve rails 312, 326.

[0082] The lower arm 341 can receive the power of the driving unit 330 and push the lower flat surface portion F2 forward, and as the guide protrusions 343 and 344 of the upper arm 342 move along the curved rails 312 and 326, the moving path of the curved moving unit 340 can be set. The lower arm 341 may include a curved rack gear 341a located in the back direction thereof to receive the power from the driving unit 330.

[0083] Figure 5 The fixed part may correspond to the fixing unit 310 , and the moving part may include the moving units 320 , 340 and the display part 100 moving together with the moving units 320 , 340 .

[0084] The driving unit 330 that provides power to the moving units 320 and 340 may include a motor 331 and a pinion 334 that transmits power of the motor 331. The motor 331 may be fixed to the horizontal base 316. Figure 3 As shown, in order to transmit force to the moving units 320 and 340 arranged in pairs in a left-right symmetrical manner, a horizontal shaft 333 may be included to transmit the power of one motor 331 to the left and right.

[0085] In the case of providing two motors 331, the component cost increases, and in order to synchronously drive a pair of moving units 320, 340, it is preferable to use one motor 331. Figure 4 As shown, the motor 331 is located between a pair of vertical bases 311, and the horizontal shaft 333 extends in the left-right direction and is respectively coupled to pinion gears 334 at the ends.

[0086] In order to distribute the force of the motor 331 to the pair of horizontal shafts 333 and change the rotation direction of the motor 331 , a plurality of gears may be used, and a gear box 332 in which the gears are located may be located at the lower portion of the motor 331 .

[0087] The pinion gear 334 may mesh with a curved rack gear 341a formed on the lower arm 341 of the curved moving unit 340, and the curved rack gear 341a may draw a curve and move when the pinion gear 334 rotates. The back surface of the lower arm 341 on which the curved rack gear 341a is formed protrudes in the back direction, so that the pinion gear 334 may draw a curved trajectory instead of a straight line and move when it rotates.

[0088] Figure 6 is a rear perspective view showing a second state of the display device 10 according to the embodiment of the present invention, Figure 7 2 is a rear view of the display device 10 in the second state according to the embodiment of the present invention.

[0089] If the driving unit 330 is activated and switches from the first state to the second state, the curve moving unit 340 pushes the lower end of the display unit 100 forward, and the upper plane portion F1 and the lower plane portion F2 of the display unit 100 combined with the linear moving unit 320 separate and move in the vertical direction, and their forward direction remains unchanged.

[0090] like Figure 7 As shown, the lower plane portion F2 of the display portion 100 can move further downward to the horizontal base 316, and as shown in FIG. Figure 6 The variable portion B may be curved, and the rear structure of the display portion located behind the variable portion B may have a movable hinge 365 so as to be able to bend and deform in the up and down directions.

[0091] The movable hinge 365 may be formed by pasting strip-shaped members arranged in a vertical direction and extending in a horizontal direction, or by forming a groove 3652 extending in a horizontal direction on the back of an elastic member.

[0092] The upper plane portion F1 and the lower plane portion F2 are guided by being combined with the moving units 320 and 340, but the shape of the variable portion B is changed, so it is difficult to set a bracket fastened to the moving units 320 and 340. The variable portion B is not combined with the moving units 320 and 340, but Figure 6 As shown, it can be fastened to the side rails 313 of the guiding movement path so as to move along the curved tracks 312, 326 along a predetermined curved track.

[0093] Figure 8 1 is a diagram showing the back structure of the display unit 100 of the display device 10 according to the embodiment of the present invention. As described above, the display unit 100 of the present invention may be composed of the upper plane portion F1, the variable portion B, and the lower plane portion F2, and the rigid back plates 361 and 362 may be combined with the upper plane portion F1 and the lower plane portion F2.

[0094] The back plate can be divided into a first back plate 361 combined with the upper plane portion F1 and a second back plate 362 combined with the lower plane portion F2. The portion corresponding to the variable portion B can omit the solid back plate to enable bending and deformation, and a movable hinge 365 can be provided.

[0095] The back plates 361 and 362 may include extensions 361a and 362a extending toward the variable portion B. The extensions 361a and 362a are not combined with the display portion 100. Therefore, when the variable portion B is bent in the second state, the extensions 361a and 362a may be separated from the back of the display portion 100 (see FIG. 1 ). Fig.15 ).

[0096] An end portion of the extension portion 361 a of the first back plate 361 and an end portion of the extension portion 362 a of the second back plate 362 may meet in the middle of the variable portion so as not to overlap.

[0097] If the motor 331 is driven in the first state, when the curve moving unit 340 moves toward the lower front side, the upper end of the extension portion 362a of the second back panel 362 located at the lower part is separated from the back side of the display unit 100, and then the lower end of the extension portion 361a of the first back panel 361 is separated from the back side of the display unit 100.

[0098] As the display portion 100 moves downward, the curved surface at the bottom of the variable portion B becomes flat again. Fig.15 As shown, the interval between the second back plate 362 and the display panel 151 may become smaller.

[0099] The living hinge 365 may be covered by extensions 361a, 362a, such as Figure 8 As shown, a hinge wing 368 for guiding the moving path of the variable portion B may protrude from the back side of the movable hinge 365 .

[0100] The hinge wing 368 may be formed of a metal material to have rigidity, and in order to fix the hinge wing 368 to the living hinge 365 , may include a wing fixing portion 3681 covering the back side of the living hinge 365 .

[0101] Fig. 9 1 and 2 are diagrams showing the side rail 313 and the hinge wing 368 of the display device 10 according to the embodiment of the present invention. (a) is an enlarged view of the third guide protrusion 3683 inserted into the side rail 313, and (b) is a side view showing a second state.

[0102] like Fig. 9 As shown in (a), the hinge wing 368 may include a third guide protrusion 3683 inserted into the side rail 313 in a manner of moving along the side rail 313 formed in a lateral direction of the vertical base 311.

[0103] like Fig. 9 As shown in (b), the upper side of the side rail 313 is straight in the vertical direction, but may include a curve that bends toward the front direction at the lower side. In the first state, the third guide protrusion 3683 of the hinge wing 368 may be located in the upper straight section of the side rail 313, but when switching to the second state, it may move to the curved section of the side rail 313, and the lower part of the display unit may be as shown. Fig. 9 The protrusion shown in (b) is shown.

[0104] like Figure 8 As shown, the hinge wing 368 can be configured in a bilaterally symmetrical manner. At this time, the third guide protrusions 3683 can be configured relative to each other.

[0105] The hinge wing 368 is made of a rigid material, so the extension parts 361a and 362a can be omitted in the portion where the wing fixing part 3681 of the hinge wing 368 is located, and the extension parts 361a and 362a are only provided between the hinge wings 368.

[0106] Fig.10 1 is an exploded perspective view of the display panel 151 and the back structure of the display device 10 of the embodiment of the present invention. The display portion 100 may be composed of the display panel 151, the movable hinge 365, and the back panels 351 and 352 located on the back of the display panel 151. The movable hinge 365 may include: a front panel 367 for attaching to the display panel 151; and a non-elastic panel 366, which covers the groove 3652 on the back of the movable hinge 365 and sets the limit of the curvature change of the variable portion B.

[0107] As described above, the hinge wings 368 exposed to the outside may be respectively located on the left and right sides of the back surface of the movable hinge 365. The portions overlapping with the extensions 361a and 362a of the back plate may be covered by the non-elastic plate 366.

[0108] A panel substrate 182 for controlling the driving of the display panel 151 may be disposed at the lower portion of the display panel 151. In order to connect the panel substrate 182 and the main substrate, as shown in FIG. Figure 8 As shown, the second back plate 362 may include an opening portion that exposes a portion of the panel substrate.

[0109] Fig.11 3 is a diagram showing a living hinge 365 of the display device 10 according to an embodiment of the present invention. The living hinge 365 may be configured to be bendable using a member 3651 of an elastic material and may have a predetermined thickness to have rigidity to support the back surface of the flexible display panel 151 .

[0110] However, if the thickness of the movable hinge 365 is thick, it is difficult to bend and deform, so the movable hinge 365 may include a groove 3652 extending in the horizontal direction on the back side to facilitate bending and deformation toward the front side. Fig.11 As shown, the groove 3652 can be cut into a V-shape.

[0111] The plurality of grooves 3652 are arranged side by side in a vertical direction, and the cross-section between the grooves 3652 is in a trapezoidal strip shape. In order to increase the rigidity of the movable hinge 365, a rigid rib 3653 may be inserted between the plurality of grooves 3652. The rigid rib 3653 may include a metal material. The rigid rib 3653 may be inserted into the elastic member 3651 of the movable hinge 365 by forming a groove therein, or may be formed as an integral type with the elastic member 3651 by double injection molding.

[0112] The rigid rib 3653 may have a length corresponding to the horizontal length of the display panel 151, but as Fig.11 As shown in (b), it can also be formed by arranging a plurality of rigid ribs 3653 cut into a predetermined length in the horizontal direction. In this case, if the end of the rigid rib 3653 is arranged to be staggered with the rigid rib 3653 adjacent in the vertical direction, the degree of freedom of length change in the vertical direction is increased, so that the bending deformation of the display panel 151 can be performed more smoothly.

[0113] Fig.12 365, a front plate 367, and a non-elastic plate 366 of a display device 10 according to an embodiment of the present invention. (a) shows a state in which the variable portion B is flat as a first state, and (b) shows a state in which the variable portion B is curved and bent as a second state.

[0114] The movable hinge 365 has a predetermined thickness, and the curvature radius of the front and back of the movable hinge 365 is different. The front of the movable hinge 365 is combined with the display panel 151, so the length change of the back of the movable hinge 365 is significantly greater than the length change of the front of the movable hinge 365.

[0115] The front panel 367 can be combined with the display panel 151, can have adhesiveness, and can be hardly deformed or slightly expanded. Since the deformation of the movable hinge 365 is large, the length change of the non-elastic plate 366 located at the back side should also be large.

[0116] Therefore, the plate located at the back of the living hinge 365 can use a material with greater elasticity, but a non-elastic plate 366 with a constant length can be used to limit the maximum bending deformation curvature.

[0117] like Fig.12 As shown in (b), the vertical length of the non-elastic plate 366 is determined corresponding to the curvature of the second state, and is closely attached to the back side of the movable hinge 365 when the variable portion B is bent.

[0118] At this time, it is not necessary to bond to the groove 3652 part, but only to adhere to the strip (rigid rib 3653) between the grooves 3652. As shown in (a), if the first state is converted, the width of the groove 3652 on the back side of the movable hinge 365 becomes narrower, so the part of the non-elastic plate 366 corresponding to the unbonded groove 3652 is bent and can protrude toward the back side (or enter between the grooves 3652).

[0119] When switching to the second state again, even if a force is applied from the front to deform the curvature of the variable portion B more greatly, the non-elastic plate 366 will not be stretched, so that the variable portion B can be supported so as not to bend further.

[0120] Fig.13 1 is a top view showing the moving units 320 and 340 of the display device 10 according to an embodiment of the present invention. The vertical base 311 of the fixed unit 310, the moving plate 321 of the linear moving unit 320, the first front bracket 322 and the rear bracket 323 are shown. The curved moving unit 340 may include: a lower arm 341 having a curved rack gear 341a formed on the back thereof; and an upper arm 342 rotatably coupled to the upper side of the lower arm 341.

[0121] The curved moving unit 340 is located in the space between the moving plate 321 and the vertical base 311. Curved tracks 312, 326 toward the upper arm 342 are formed on both the vertical base 311 and the moving plate 321, and the upper arm 342 of the curved moving unit 340 is combined with the vertical base 311 and the moving plate 321 at the same time by using guide protrusions 343, 344 protruding on both sides thereof.

[0122] Fig.14 yes Figure 3 AA section view, Fig.15 yes Figure 4 A′-A′ cross-sectional view. Fig.14 and Fig.15 321 is a diagram viewed from the outside of the moving plate 321. When the motor 331 is driven and the pinion 334 rotates, the curved rack gear 341a is pushed forward to the lower side, so that the lower side plane portion F2 is as shown in FIG. Fig.15 As shown, it protrudes toward the lower front side.

[0123] The lower plane portion F2 moves downward, so the variable portion B and the upper plane portion F1 are also pulled downward, and as shown in FIG. Fig.15 As shown, the linear moving unit 320 can also move downward.

[0124] Fig.16 yes Figure 3 BB cross-sectional view, Fig.17 yes Figure 4 B′-B′ cross-sectional view. Fig.16 and Fig.17 3 is a diagram of the upper arm 342 viewed from the inner side of the moving plate 321. The upper arm 342 and the first curved track 312 formed on the vertical base 311 are shown, and the first guide protrusion 343 formed on the upper arm 342 can be inserted into the first curved track 312 and move. The first curved track 312 plays a role in guiding the moving direction of the curved moving unit 340.

[0125] like Fig.16 and Fig.17As shown, the first curved track 312 may be configured with a pair in the front-to-back direction, and the length of the rear first curved track 312b located at the rear may be longer than the front first curved track 312a located at the front. This is because the curve moving unit 340 draws a curve and rotates, so the rotation radius of the rear first guide protrusion 343b located at the end of the upper arm 342 is larger, thereby moving a longer distance.

[0126] and Fig.16 The angle of the upper arm 342 is compared to Fig.17 The upper arm 342 is inclined at an angle so that the rear is located further down, and the position of the lower end of the pair of first curved rails 312 may be different from the position of the upper end.

[0127] If the curved moving unit 340 moves to the lower front (①), the lower plane portion F2 moves downward (②), and the variable portion B and the upper plane portion F1 also move downward (③). The driving force of the upper plane portion F1 and the linear moving unit 320 is transmitted through the display unit 100 and applies a load to the display unit 100, so that the display panel may be damaged. In addition, when switching from the second state to the first state, it is necessary to push the linear moving unit 320 upward, so compared with the switching from the first state to the second state, the transmission of the driving force of the motor 331 cannot be smoothly achieved.

[0128] Thus, a second curved track 326 may be formed on the moving plate 321, and a second guide protrusion 344 inserted into the second curved track 326 from the upper arm 342 may be further provided to transmit the driving force applied to the curved moving unit 340 to the linear moving unit 320 by directly fastening the curved moving unit 340 and the linear moving unit 320. The second guide protrusion 344 may be formed on the opposite side of the first guide protrusion 343.

[0129] Figures 18 to 20 1 is a diagram illustrating sliding actions of the linear movement unit 320 and the curved movement unit 340 of the display device 10 according to the embodiment of the present invention. Fig.18 yes Figure 4 CC cross-sectional view, Fig. 20 yes Figure 7 C′-C′ cross-sectional view, Fig.19 2 is a cross-sectional view showing the linear movement unit 320 and the curved movement unit 340 at an intermediate position between the first state and the second state.

[0130] The upper arm 342 connected to the upper side of the lower arm 341 is fastened through the moving plate 321 as the linear moving unit 320, the second guide protrusion 344, and the second curved track 326, so that the upper arm 342 can transmit the force pulling the moving plate 321 to the lower side.

[0131] However, the curved moving unit 340 draws a curve and moves, and the linear moving unit 320 performs a linear motion in the up and down directions. Therefore, the second curved track 326 can be designed to offset the horizontal movement of the curved moving unit 340 performing the curved motion and transmit the vertical force to the moving plate 321.

[0132] like Fig.18 As shown, a pair of second curved tracks 326 may be included, and may include a front second curved track 326a located in the front and a second curved track 326b located in the rear. The second guide protrusion 344 formed on the upper arm 342 may also include a front second guide protrusion 344a moving along the front second curved track 326a, and a rear second guide protrusion 344b moving along the rear second curved track 326b.

[0133] The curve moving unit 340 rotates and moves, so that Fig.18 and Fig. 20 As shown, the upper arm 342 is tilted at different angles in the first state and the second state. In the second state, the curve moving unit 340 is tilted and protruded forward, so the upper arm 342 constituting the upper side of the curve moving unit 340 is tilted more vertically than in the first state.

[0134] Therefore, corresponding to the angle change of the upper arm 342, the angle of the line B connecting the lower end of the front second curved track 326a and the lower end of the rear second curved track 326b is steeper than the angle of the line A connecting the upper end of the front second curved track 326a and the upper end of the rear second curved track 326b.

[0135] The linear moving unit 320 and the curved moving unit 340 both move up and down, but the moving distances of the upper side and the lower side of the curved moving unit 340 are different. Compared with the linear moving unit 320, the vertical moving distance of the lower side of the curved moving unit 340 is shorter, but protrudes forward. Compared with the linear moving unit 320, the vertical moving distance of the upper side of the curved moving unit 340 may be greater.

[0136] This is because the curved moving unit 340 performs a rotational movement while performing a vertical movement based on the point meshing with the pinion gear 334 , and therefore the vertical movement distances of the lower end and the upper end thereof are different.

[0137] Therefore, the second curved track 326 reflects the difference in the movement trajectories of the linear moving unit 320 and the curved moving unit 340 and has a convex shape toward the back. The first curved track 312 is formed on the vertical base 311 and has a longer length, but the second curved track 326 is formed on the moving plate 321 moving in the vertical direction and has a shorter length than the first curved track 312.

[0138] The front second curved track 326a and the rear second curved track 326b have different peak points P1 and P2 (or bending points) protruding toward the back side of the second curved track 326. If the peak point P1 of the front second curved track 326a and the peak point P2 of the rear second curved track 326b are the same, the second guide protrusion 344 changes direction (changes to the front) when reaching the peak points P1 and P2, and becomes difficult to move.

[0139] When the rear second guide protrusion 344b reaches the peak of the rear second curved track 326b, the front second curved track 326a is still in the process of moving downward, so the rear second guide protrusion 344b can pass through the peak point P2 in the rear second curved track 326b and move along the rear second curved track 326b inclined forward.

[0140] like Fig.19 As shown, when the front second guide protrusion 344a reaches the peak point P1 of the front second curved track 326a, the upper arm 342 can move downward under the action of the force of the rear second curved track 326b moving downward, and the front second guide protrusion 344a can continue to move downward along the front second curved track 326a.

[0141] In addition, the curvature of the front second curved track 326a is greater than that of the rear second curved track 326b, and the distance between the upper end and the lower end is short. That is, the curvature radius of the rear second curved track 326b is greater than the curvature radius of the front second curved track 326a, and the length of the rear second curved track 326b is longer than the length of the front second curved track 326a. This is because the moving trajectory of the upper arm 342 is different from the part and end of the lower arm 341.

[0142] When the second guide protrusion 344 reaches the lower end of the second curved track 326, the first guide protrusion 343 also reaches the lower end of the first curved track 312 and is converted to the second state. In the second state, the angle of the upper arm 342 can be configured to be steeper than the first state, and the lower arm 341 can be configured to protrude forward at an angle inclined from the vertical direction.

[0143] On the contrary, when the display unit 100 moves upward in the opposite direction, the lower arm 341 moves upward and changes its angle, and the upper arm 342 can move along the second curved track 326 and push the moving plate 321 upward, so that the upper part of the display unit 100 moves upward.

[0144] As described above, the driving force of the curved moving unit 340 can be directly transmitted to the linear moving unit 320 through the second curved track 326 to guide the display unit 100 to move upward, thereby enabling more stable movement compared to a structure in which force is transmitted from the display unit 100 to the linear moving unit 320 .

[0145] An object of the present invention is to provide a display device 10 whose position is changeable, can be introduced or led out, can be led out when needed and can be stored when not needed, thereby reducing the size of the exposed screen.

[0146] In addition, the shape of the display device 10 of the present invention can also be changed, so there is an advantage that it can be introduced or led out even if the storage space and the lead-out direction are inconsistent.

[0147] By transmitting the force of the motor 331 through the moving unit, the lower curved motion and the upper linear motion of the display portion 100 can be simultaneously performed in vertical linkage using the force of one motor 331 .

[0148] Even in a bent state, the device has rigidity, so touch input and the like can be realized, and durability can be ensured by preventing deformation in the reverse direction.

[0149] The above detailed description should not be interpreted as limiting in all aspects, but should be considered as exemplary. The scope of the present invention should be determined according to the reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.
