Figure 3B is a perspective view of a slidable display device according to an embodiment of the present disclosure. Figure 4 is a partial cross-sectional view of a slidable display device according to an embodiment of the present disclosure.

[0045] Will refer to Figures 1 to 4 The structure of a slidable display device 10 according to one embodiment of the present disclosure is described.

[0046] The slidable display device 10 according to the embodiment of the present disclosure may be installed in a space between an outer peripheral panel of a vehicle and a roof panel P of the vehicle disposed below the outer peripheral panel.

[0047] The roof panel P of the vehicle may include a pair of support ribs P-1 protruding downward and disposed to be spaced apart from each other. The roof panel P of the vehicle may include an opening P-2 formed in a space between the pair of support ribs P-1.

[0048] The display panel assembly 400 of the slidable display device 10 may slide and extend into the vehicle through the opening P-2.

[0049] Although not illustrated in the drawings, the slidable display device 10 may be applied to other objects having a ceiling in addition to the roof panel P of the vehicle.

[0050] The slidable display device 10 includes a mounting frame 100 , a guide member 200 , a panel transfer part 300 , a display panel assembly 400 , and a moving support part 500 .

[0051] The mounting frame 100 may be disposed in a space between an outer panel of a vehicle and a roof panel P of the vehicle disposed below the outer panel. The guide member 200 , the panel transfer part 300 , and the moving support part 500 are mounted on the mounting frame 100 .

[0052] The guide member 200 is installed inside the mounting frame 100 , and guides the sliding movement of the display panel assembly 400 .

[0053] The panel transfer member 300 slides the display panel assembly 400 in a state where the panel transfer member 300 is fixed inside the mounting frame 100 .

[0054] The moving support member 500 is installed at one end of the mounting frame 100 , and is configured to support the sliding movement of the display panel assembly 400 while sliding together with the display panel assembly 400 .

[0055] In the following, we will refer to Figure 5 The mounting frame 100 and the guide member 200 are described in more detail.

[0056] Figure 5 is a perspective view of a mounting frame and a guide member of a slidable display device according to an embodiment of the present disclosure.

[0057] The mounting frame 100 is fixed in a space between an outer peripheral panel of a vehicle and a roof panel P of the vehicle disposed below the outer peripheral panel. The mounting frame 100 defines a frame constituting an outer shape of the slidable display device 10 .

[0058] Reference Figure 5 The mounting frame 100 may include a pair of first supporting frames 110 , a second supporting frame 120 , a mounting bracket 130 , and a fixing bracket 140 .

[0059] A pair of first supporting frames 110 may be respectively disposed at opposite sides of the mounting frame 100. That is, a pair of first supporting frames 110 may be respectively disposed at opposite sides of the mounting frame 100 orthogonal to the sliding movement direction of the display panel assembly 400.

[0060] The second supporting frame 120 may be disposed at ends of the pair of first supporting frames 110 , and connect and support the pair of first supporting frames 110 .

[0061] A plurality of mounting brackets 130 are fixed to outer surfaces of the pair of first support frames 110. The mounting brackets 130 may be fixed to an inner surface of a peripheral panel of the vehicle.

[0062] A plurality of fixing brackets 140 are fixed to inner surfaces of the pair of first supporting frames 110. The coupling plate 310 of the panel transfer member 300 may be fixed to and supported on the fixing brackets 140.

[0063] Reference Figures 3B to 5 , the guide member 200 is disposed at one end of the mounting frame 100 , and guides the sliding movement of the display panel assembly 400 .

[0064] The guide member 200 may include a plurality of upper rollers 210 and a plurality of lower rollers 220. The plurality of upper rollers 210 and the plurality of lower rollers 220 are each provided in the form of an idle roller. The plurality of upper rollers 210 and the plurality of lower rollers 220 are provided to face each other in an upward / downward direction. Therefore, the display panel assembly 400 can stably slide while passing between the plurality of upper rollers 210 and the plurality of lower rollers 220.

[0065] The plurality of upper rollers 210 are rotatably coupled to inner surfaces of the pair of first supporting frames 110 .

[0066] The plurality of upper rollers 210 support the sliding movement of the display panel assembly 400 while rotating through friction with the display panel assembly 400 sliding in a first direction among the moving directions of the display panel assembly 400 or sliding in a second direction opposite to the first direction, wherein the display panel assembly 400 extends into the vehicle through the opening P-2 along the first direction.

[0067] A pair of upper rollers 210 facing each other among the plurality of upper rollers 210 will be described. The pair of upper rollers 210 are configured to be connected in a direction orthogonal to the sliding movement direction of the display panel assembly 400. Therefore, the pair of upper rollers stably support the sliding movement of the display panel assembly 400 while contacting a surface of the display panel assembly 400 opposite to a surface on which the display panel 410 is provided.

[0068] The plurality of lower rollers 220 are rotatably coupled to inner surfaces of the pair of first supporting frames 110. The plurality of lower rollers 220 are disposed below the plurality of upper rollers 210, and define a sliding movement path of the display panel assembly 400 together with the plurality of upper rollers 210.

[0069] A pair of lower rollers 220 facing each other among the plurality of lower rollers 220 will be described. Unlike the plurality of upper rollers 210, the pair of lower rollers 220 are not connected to each other and support two opposing parts of the sliding display panel assembly 400. Since the pair of lower rollers 220 facing each other are not connected to each other, the display panel 410 of the display panel assembly 400 slides without its other side being covered.

[0070] The plurality of lower rollers 220 define: a first path extending from the lower roller 220 at the other end along a first direction; a second path extending along a second direction inclined at an angle of 90° to 130°, particularly 110°, relative to the first direction; and a third path configured to connect the first path and the second path and allow the display panel assembly 400 to move between the first path and the second path when having a specific curvature.

[0071] That is, the plurality of lower rollers 220 define a first path extending from the lower roller 220 at the other end in a direction parallel to the first support frame 110, a second path extending to the end of the mounting frame 100 at an inclined angle to the first path, and a third path configured to connect the first path and the second path and arranged while having an arc shape between the first path and the second path.

[0072] When the second direction is inclined at an inclination angle less than 90° in the transfer path of the display panel assembly 400, the display panel assembly 400 is extended while being excessively bent, which may make it inconvenient to view the image displayed on the display panel 410 and increase the stress applied to the display panel 410.

[0073] In the case where the second direction is tilted at an inclination angle greater than 130° in the transfer path of the display panel assembly 400, the display panel assembly 400 is extended while being over-unfolded, which may make it difficult to view the image displayed on the display panel 410 and cause damage to the movable support member 500 connected to the connecting plate 310 when the display panel assembly 400 slides.

[0074] In the following, reference will be made to Figures 6 to 12 The panel transfer member 300 and the display panel assembly 400 are described in more detail.

[0075] Figure 6 is a perspective view of a panel transfer component of a slidable display device according to an embodiment of the present disclosure. Figure 7 is an exploded perspective view of a panel transfer component of a slidable display device according to an embodiment of the present disclosure. Figure 8 is a perspective view of a panel transfer component of a slidable display device according to an embodiment of the present disclosure. Fig. 9 is a schematic perspective view related to the connection between a panel transfer component and a display panel assembly of a slidable display device according to an embodiment of the present disclosure. Fig.10 is an exploded perspective view of a display panel assembly of a slidable display device according to an embodiment of the present disclosure. Fig.11 is a perspective view of a slidable display device according to an embodiment of the present disclosure. Fig.12 is a perspective view illustrating a state in which a display panel is extended when a display panel assembly of a slidable display device according to an embodiment of the present disclosure slides.

[0076] The panel transfer member 300 is mounted on the mounting frame 100 and slides the display panel assembly 400 .

[0077] Reference Figures 6 to 9The panel transfer component 300 may include a connecting plate 310, a pair of support blocks 320, a rotating shaft 330, a driving motor 340, a carrier 350, a pair of supports 360, a pair of first guide rails R1, a pair of first linear movement (LM) blocks LM1, a first transfer bridge B1, a connecting plate 370, and a connecting bridge 380.

[0078] The coupling plate 310 is fixed to a plurality of fixing brackets 140 provided on the mounting frame 100. A pair of support blocks 320, a motor support member 342, and a pair of support pieces 360 may be fixed to a lower surface of the coupling plate 310.

[0079] The coupling plate 310 includes a moving guide groove H formed at one end thereof. The moving guide groove H defines a path through which a flexible flat cable (FFC cable) 460 slides by a first support plate 510 of a moving support member 500 mounted on the coupling plate 310. That is, one side of the moving guide groove H is blocked by the first support plate 510, thus having a hole shape, and the moving guide groove H defines a path through which the FFC cable 460 that slides by the movement of the carrier 350 passes.

[0080] A pair of support blocks 320 are fixed to the lower surface of the coupling plate 310. The pair of support blocks 320 are disposed in a sliding movement direction of the display panel assembly 400 to be spaced apart from each other.

[0081] The bearings are provided inside the pair of support blocks 320. One end and the other end of the rotating shaft 330 are rotatably mounted in the bearings provided in the pair of support blocks 320, respectively. The pair of bearings fixes the rotating shaft 330 at a predetermined position that is not eccentric. The pair of bearings supports the weight of the rotating shaft 330 that rotates. The pair of bearings supports the load applied to the rotating shaft 330.

[0082] The rotating shaft 330 can move the carrier 350 along the sliding movement direction of the display panel assembly 400 by means of the driving force transmitted by the driving motor 340 .

[0083] The rotating shaft 330 may have a ball screw shape. The rotating shaft 330 may convert the rotational motion of the driving motor 340 into a linear reciprocating motion of the carrier 350 disposed on the rotating shaft 330. The rotating shaft 330 may be rotated by the driving motor 340 and cause the carrier 350 to linearly move to one side or the other side toward the one side support block 320 or the other side support block 320.

[0084] The driving motor 340 is connected to the other side support block 320 of the pair of support blocks 320 , and transmits a driving force to the rotating shaft 330 .

[0085] The driving motor 340 is connected to the rotating shaft 330 through a coupling 341. Even if the rotating shaft 330 deviates from concentricity during a process in which the carrier 350 moves, the coupling 341 holds the rotating shaft 330 so that the rotating shaft 330 rotates in a predetermined axial direction.

[0086] In a state where the driving motor 340 is connected to the other side support block 320, the driving motor 340 may be supported by a motor support member 342 disposed between the driving motor 340 and the coupler 341. The motor support member 342 is fixed to a lower surface of the other end of the coupling plate 310.

[0087] The driving motor 340 may be connected to a power generation component (not illustrated) such as an external power source or an embedded battery and supplied with power. The driving motor 340 generates a rotation force and transmits the driving force to the rotating shaft 330 having a ball screw shape.

[0088] The driving motor 340 may rotate the rotation shaft 330 in response to the position of the first LM block LM1 received from a pair of position sensors S through a power generation component (not illustrated).

[0089] The carrier 350 may be disposed on the rotating shaft 330 and linearly moved along the sliding movement direction of the display panel assembly 400 by the driving force transmitted by the driving motor 340. The carrier 350 may linearly reciprocate along a first direction among the movement directions of the display panel assembly 400 or a second direction opposite to the first direction, wherein the display panel assembly 400 extends into the vehicle through the opening P-2 along the first direction.

[0090] A pair of support members 360 may be disposed at opposite sides of the pair of support blocks 320. The pair of support members 360 may be fixed to a lower surface of the coupling plate 310 along a moving direction of the carrier 350.

[0091] A pair of position sensors S may be provided on any one of the pair of support members 360 and spaced apart from each other. The pair of position sensors S may be provided on portions of the support member 360 corresponding to positions where the pair of support blocks 320 are provided, respectively.

[0092] The pair of position sensors S may detect the position of the first LM block LM1 moving together with the carrier 350. Position signals related to the first LM block LM1 detected by the pair of position sensors S may be transmitted to a power generation part (not illustrated).

[0093] The pair of position sensors S may each be provided in the form of a limit sensor for detecting the position of the first LM block LM1 to limit the movement of the carrier 350. The movement of the carrier 350 is limited by the pair of position sensors S, so that damage or breakage of the panel transfer member 300 or occurrence of noise can be suppressed in advance.

[0094] The power generation component (not illustrated) may control (turn on or off) the operation of the drive motor 340 in response to the received position signal associated with the first LM block LM1. The power generation component (not illustrated) may perform control in response to the received position signal associated with the first LM block LM1 to allow the drive motor 340 to rotate the rotation shaft 330.

[0095] The panel transferring member 300 may include a linear movement guide (LM guide) LMG1 to support smooth sliding movement of the display panel assembly 400 .

[0096] The LM guide LMG1 includes a pair of first guide rails R1 and a pair of first LM blocks LM1.

[0097] A pair of first guide rails R1 are respectively provided and fixed to lower surfaces of a pair of support members 360 .

[0098] A pair of first LM blocks LM1 are movably disposed on a pair of first rails R1. A pair of first LM blocks LM1 are connected to the carrier 350 (see Figure 8 ). Therefore, the pair of first LM blocks LM1 cooperates with the movement of the carrier 350. That is, when the carrier 350 reciprocates in the first direction or the second direction, the pair of first LM blocks LM1 connected to the carrier 350 through the first transfer bridge B1 also reciprocates in the first direction or the second direction along the pair of first guide rails R1 together with the carrier 350.

[0099] The first transfer bridge B1 is connected to the lower surface of the carrier 350 and the lower surfaces of the pair of first LM blocks LM1 , and connects the carrier 350 and the pair of first LM blocks LM1 .

[0100] The first transfer bridge B1 is also connected to the second transfer bridge B2 of the display panel assembly 400. Therefore, the pair of first LM blocks LM1 may slide by the reciprocating movement of the carrier 350, and the display panel 410 of the display panel assembly 400 may also slide by the reciprocating movement of the carrier 350.

[0101] The connection plate 370 may be coupled to the connection bridge 380 provided on the carrier 350. The interface board 450 of the display panel assembly 400 may be mounted on the connection plate 370 and move to one side together with the movement of the carrier 350. Therefore, when the carrier 350 reciprocates in the first direction or the second direction, the pair of first LM blocks LM1 also reciprocates, and the second transfer bridge B2 connected to the first transfer bridge B1 coupled to the lower surface of the carrier 350 and the lower surface of the pair of first LM blocks LM1 also reciprocates.

[0102] Since the second transfer bridge B2 is integrally connected with the first transfer bridge B1 , the display panel 410 of the display panel assembly 400 slides in the first direction or the second direction while cooperating with the carrier 350 and the pair of first LM blocks LM1 .

[0103] Since the interface plate 450 of the display panel assembly 400 is disposed on the connection plate 370 coupled to the connection bridge 380 , the interface plate 450 slides in the first direction or the second direction together with the display panel 410 through the reciprocating movement of the carrier 350 simultaneously with the movement of the display panel 410 .

[0104] That is, when the rotating shaft 330 rotates through the operation of the driving motor 340, the carrier 350 reciprocates linearly in the first direction or the second direction, and the interface plate 450 set on the connecting plate 370 and the display panel 410 integrally connected to the first transfer bridge B1 through the second transfer bridge B2 also slide in the first direction or the second direction simultaneously with the movement of the carrier 350 when operating in coordination with the carrier 350.

[0105] When the display panel 410 and the interface board 450 slide simultaneously, the display panel assembly 400 slides in the first direction or the second direction, and the movable support member 500 slides in the first direction or the second direction while covering the display panel assembly 400 and slidingly moving the display panel assembly 400 .

[0106] The display panel assembly 400 may be slidably mounted on the mounting frame 100 .

[0107] Reference Figures 9 to 12 The display panel assembly 400 may include a display panel 410 , a printed circuit board 420 , a middle cover 430 , a plurality of rear bars 440 , an interface board 450 , an FFC cable 460 , a second transfer bridge B2 , and a dummy panel 470 .

[0108] The display panel 410 may slide downward through the opening P-2.

[0109] The display panel 410 may include a display element configured to display an image, a drive element configured to operate the display element, and a line configured to send various types of signals to the display element and the drive element. The display panel 410 is arranged parallel to the coupling plate 310 at ordinary times. When the display panel 410 extends downward through the opening P-2, the display panel 410 tilts and moves in a direction different from the direction of the coupling plate 310. The display panel 410 may have flexibility because during the process in which the direction of the display panel 410 changes when the display panel 410 tilts and moves, the display panel 410 needs to be bent into a curved shape.

[0110] Reference Figure 3BThe display panel 410 may include a display part DP. The display part DP may include a constant display area 411 and an extended display area 412.

[0111] The always-on display area 411 is an area of ​​the display part DP that is set in an always-on display form and maintained in a state of extending downward through the opening P-2. Therefore, the always-on display area 411 can be used as an area where a picture can be displayed at ordinary times. The always-on display area 411 can display information such as date, weather, time, etc. However, the present disclosure is not limited to this. The always-on display area 411 can be in a closed state without displaying a picture.

[0112] The printed circuit board 420 may be disposed on one side surface of the always-on display area 411 to operate the display part DP.

[0113] When the extended display area 412 slides downward through the opening P- 2 , the middle cover 430 , the plurality of rear bars 440 , and the dummy panel 470 also slide through the opening P- 2 .

[0114] In a state where the extended display area 412 is moved, the extended display area 412 and the always-on display area 411 may display an image together or individually.

[0115] The printed circuit board 420 is electrically connected to the end of the display panel 410. The printed circuit board 420 is a component configured to supply a signal to a driver integrated circuit (IC). The printed circuit board 420 supplies various signals such as a drive signal or a data signal to the driver IC. A timing controller, a power supply component, etc. may be provided on the printed circuit board 420 and work to display images in the always-on display area 411 and the extended display area 412.

[0116] The middle cover 430 is disposed on one surface of the display panel 410 and supports the display panel 410 and the printed circuit board 420. The middle cover 430 may have a larger area than the display panel 410 to protect the display panel 410 from external impact.

[0117] The middle cover 430 may include a material having flexibility so that even if the display panel assembly 400 slides repeatedly, the middle cover 430 will not be deformed. Specifically, the middle cover 430 may include a material such that the stress applied to the middle cover 430 during the process of the display panel 410 sliding along the guide member 200 is equal to or lower than the yield strength (yield stress) of the middle cover 430. The middle cover 430 may include materials such as metal, rubber, plastic or fabric. However, as long as the material of the middle cover 430 satisfies physical property conditions such as thermal deformation amount, curvature radius or rigidity, the material of the middle cover 430 may be variously changed according to the design. However, the present disclosure is not limited thereto.

[0118] The middle cover 430 may have a small thickness so that the middle cover 430 is not deformed even if the display panel assembly 400 slides repeatedly.

[0119] The middle cover 430 includes a plurality of opening portions. The middle cover 430 may include a pattern having a shape in which a plurality of hole-shaped opening portions are repeatedly provided. For example, the plurality of opening portions may have various shapes, such as an elliptical shape or a polygonal shape. However, the present disclosure is not limited thereto. Since the plurality of opening portions are flexibly deformed, even if stress is applied to the display panel assembly 400 when the display panel assembly 400 slides repeatedly, the stress applied to the middle cover 430 may be minimized.

[0120] The first bonding layer AD1 is disposed between the middle cover 430 and the display panel 410 .

[0121] The first bonding layer AD1 may bond the middle cover 430 and the display panel 410. The first bonding layer AD1 may be made of a material having bonding properties.

The first bonding layer AD1 may include an optically clear adhesive (OCA) or a pressure sensitive adhesive (PSA). However, the present disclosure is not limited thereto.

[0122] A plurality of rear bars 440 may be disposed on one surface of the middle cover 430 .

[0123] The plurality of rear bars 440 supports the display panel 410 and the middle cover 430. The thickness of the plurality of rear bars 440 may be greater than the thickness of the middle cover 430. The plurality of rear bars 440 may protect the display panel 410 and the middle cover 430 from external impact.

[0124] The plurality of rear bars 440 may include a material having rigidity. The plurality of rear bars 440 may include a material such as a plastic material or a metal material such as stainless steel (SUS) or Invar. However, as long as the material of the plurality of rear bars 440 meets physical property conditions such as thermal deformation, radius of curvature or rigidity, the material of the plurality of rear bars 440 may be variously changed according to the design. However, the present disclosure is not limited thereto.

[0125] The second bonding layer AD2 is disposed between the plurality of rear bars 440 and the middle cover 430 .

The second bonding layer AD2 may include a material having elasticity. The second bonding layer AD2 may include a foam pad and an elastic resin. However, the present disclosure is not limited thereto.

[0127] The interface board 450 is connected to the printed circuit board 420 to display an image on the display part DP. The interface board 450 can be connected to the image controller so as to be supplied with power and control the image displayed on the display part DP. The interface board 450 can be connected to the printed circuit board 420 through the FFC cable 460.

[0128] The interface plate 450 is mounted on the connection plate 370, and the connection plate 370 is coupled to the connection bridge 380, and the connection bridge 380 is coupled to the carrier 350. When the connection plate 370 is moved in the first direction or the second direction by the movement of the carrier 350, the interface plate 450 slides. When the carrier 350 moves, the interface plate 450 and the second transfer bridge B2 of the middle cover 430 that is integrally coupled to the first transfer bridge B1 slide in the first direction or the second direction at the same time. The interface plate 450 is maintained in a state where the interface plate 450 moves only on the upper side of the mounting frame 100. The interface plate 450 slides in the first direction or the second direction on the upper side of the connection plate 310.

[0129] The FFC cable 460 electrically connects the interface board 450 and the printed circuit board 420. The FFC cable 460 connects the interface board 450 and the printed circuit board 420, and allows the interface board 450 and the printed circuit board 420 to send or receive data, signals or electricity to display images on the display component DP. The FFC cable 460 may include a flexible material. The FFC cable 460 is moved in the first direction or the second direction by means of the movement of the first transfer bridge B1 and the movement of the connecting plate 370 connected to the connecting bridge 380 by the display panel 410. When the FFC cable 460 moves in the first direction or the second direction, the FFC cable 460 moves downward (first direction) or upward (second direction), and passes through the moving guide groove H of the connecting plate 310 in a curved shape, and the FFC cable 460 slides along the second support plate 520 and the third support plate 530 of the mobile support component 500.

[0130] The second transfer bridge B2 is provided at the upper end of the middle cover 430. The upper surface of the second transfer bridge B2 is coupled to the lower surface of the first transfer bridge B1. The second transfer bridge B2 integrally coupled to the first transfer bridge B1 moves the middle cover 430 in the first direction or the second direction while the carrier 350 moves in the first direction or the second direction by the operation of the driving motor 340, so that the display panel 410 extends downward or slides upward through the opening P-2 and is accommodated in the mounting frame 100.

[0131] The dummy panel 470 may be disposed at an upper end of the display panel 410 opposite to the lower end of the display panel 410 provided with the printed circuit board 420. Since the dummy panel 470 is disposed at the upper end of the display panel 410, a specific length of the always-on display area 411 of the display panel 410 may be ensured, so that the always-on display area 411 of the display panel 410 is maintained in a state of extending downward through the opening P-2 at ordinary times, so that the always-on display area 411 of the display panel 410 having a predetermined length is used in an always-on display form.

[0132] In the following, reference will be made to Figures 13 to 15 The moving support member 500 is described in detail.

Fig.14 is a perspective view illustrating a state in which a moving support member of a slidable display device according to an embodiment of the present disclosure is extended downward as a display panel assembly slides. Fig.15 is an exploded perspective view of a moving support member of a slidable display device according to an embodiment of the present disclosure.

[0134] The moving support member 500 may be provided at one end of the mounting frame 100. The moving support member 500 is connected to the display panel assembly 400, and covers and supports the display panel assembly 400 at one side. The moving support member 500 may extend downward by the sliding movement of the display panel assembly 400.

[0135] Reference Figures 13 to 15 The moving support member 500 may include a first support plate 510 , a plurality of second rails R2 , a plurality of second LM blocks LM2 , a second support plate 520 , a plurality of third rails R3 , a plurality of third LM blocks LM3 , a third support plate 530 , a connecting rod 540 , and a cover plate 550 .

[0136] The first support plate 510 may be coupled to one end of the coupling plate 310, which is fixed to the fixing bracket 140 of the mounting frame 100. The first support plate 510 covers the display panel assembly 400 accommodated in the mounting frame 100, and supports the loads of the plurality of second rails R2, the plurality of second LM blocks LM2, the second support plate 520, the plurality of third rails R3, the plurality of third LM blocks LM3, the third support plate 530, the connection rod 540, and the cover plate 550.

[0137] While the always-on display area 411 remains below the roof panel P of the vehicle, multiple second guide rails R2, multiple second LM blocks LM2, a second support plate 520, multiple third guide rails R3, multiple third LM blocks LM3, a third support plate 530, a connecting rod 540, and a cover plate 550 can be arranged on the other side of the first support plate 510 while overlapping each other.

[0138] The moving support member 500 may include one or more LM guides to support smooth sliding movement of the second and third support plates 520 and 530 that slide obliquely upward or downward according to the sliding movement of the display panel assembly 400. The LM guide may be in the form of a guide rail and an LM block.

[0139] In the slidable display device 10 according to the embodiment of the present disclosure, the second LM guide LMG2 and the third LM guide LMG3 may be provided on the moving support member 500 .

[0140] The second LM guide LMG2 includes a plurality of second rails R2 and a plurality of second LM blocks LM2. When the carrier 350 moves in the first direction or the second direction by operation of the driving motor 340, the second LM guide LMG2 slides the second support plate 520 downward (first direction) or upward (second direction).

[0141] A plurality of second guide rails R2 are provided on the other side surface of the first support plate 510 .

[0142] The plurality of second LM blocks LM2 may be respectively disposed on the plurality of second rails R2 and slide. When the carrier 350 moves in the first direction or the second direction by the operation of the driving motor 340, the plurality of second LM blocks LM2 slide to move the second support plate 520 downward or upward.

[0143] The second support plate 520 is coupled to the other side surfaces of the plurality of second LM blocks LM2 , and slides in the first direction or the second direction by the sliding movement of the plurality of second LM blocks LM2 .

[0144] In a state where the printed circuit board 420 and the cover plate 550 are coupled to the second support plate 520, the second support plate 520 moves together with the printed circuit board 420 and the cover plate 550. That is, when the display panel 410 and the interface board 450 are moved in the first direction or the second direction by the sliding movement of the carrier 350, the second support plate 520 may move together with the display panel assembly 400 according to the sliding movement of the display panel assembly 400.

[0145] The second support plate 520 covers one side of the FFC cable 460 that moves with the movement of the interface plate 450 in the first direction or the second direction. The second support plate 520 defines a moving path of the FFC cable 460. The second support plate 520 limits the moving path of the FFC cable 460 to the inner side of the guide ribs formed on opposite sides. The FFC cable 460 is moved in the first direction or the second direction by the display panel 410 by means of both the movement of the first transfer bridge B1 and the movement of the connecting plate 370 connected to the connecting bridge 380. When the FFC cable 460 moves in the first direction or the second direction, the FFC cable 460 moves downward or upward while passing through the moving guide groove H of the connecting plate 310 in a curved shape, and the FFC cable 460 slides along the second support plate 520 in the first direction or the second direction.

[0146] The third LM guide LMG3 includes a plurality of third rails R3 and a plurality of third LM blocks LM3. When the carrier 350 moves in the first direction or the second direction by operation of the driving motor 340, the third LM guide LMG3 slides the third support plate 530 downward (first direction) or upward (second direction).

[0147] A plurality of third guide rails R3 are provided on the other side surface of the second support plate 520 .

[0148] The third LM blocks LM3 may be respectively disposed on the third rails R3 and slide. When the carrier 350 moves in the first direction or the second direction by the operation of the driving motor 340, the third LM blocks LM3 slide to move the third support plate 530 downward or upward.

[0149] The third support plate 530 is coupled to the other side surfaces of the plurality of third LM blocks LM3 , and slides in the first direction or the second direction by the sliding movement of the plurality of third LM blocks LM3 .

[0150] In a state where the printed circuit board 420 and the cover plate 550 are coupled to the third support plate 530, the third support plate 530 moves together with the printed circuit board 420 and the cover plate 550. That is, when the display panel 410 and the interface board 450 are moved in the first direction or the second direction by the sliding movement of the carrier 350, the third support plate 530 may move together with the display panel assembly 400 according to the sliding movement of the display panel assembly 400.

[0151] The third support plate 530 covers one side of the FFC cable 460 that moves with the movement of the interface plate 450 in the first direction or the second direction. The third support plate 530 defines a moving path of the FFC cable 460. The FFC cable 460 is moved in the first direction or the second direction by the display panel 410 by means of both the movement of the first transfer bridge B1 and the movement of the connection plate 370 connected to the connection bridge 380. When the FFC cable 460 moves in the first direction or the second direction, the FFC cable 460 moves downward or upward while passing through the moving guide groove H of the coupling plate 310 in a curved shape, and the FFC cable 460 slides in the first direction or the second direction along the third support plate 530 via the second support plate 520.

[0152] The cover plate 550 is coupled to one or more connecting bars 540 disposed on the third support plate 530 and covers the printed circuit board 420. The cover plate 550 may be disposed on the printed circuit board 420. Specifically, the cover plate 550 may be installed at an end of the middle cover 430 disposed on the printed circuit board 420 and cover the printed circuit board 420.

[0153] The moving support member 500 of the slidable display device 10 according to the embodiment of the present disclosure may further include a plurality of support rollers 560 .

[0154] A plurality of support rollers 560 may be provided on the other side surface of the first support plate 510 and on opposite sides of the second guide rail R2. That is, the plurality of support rollers 560 are provided in a manner that the second guide rail R2 is interposed therebetween, and support the display panel assembly 400 that slides in the first direction or the second direction. Therefore, the FFC cable 460 moves in the first direction or the second direction along the space between the plurality of support rollers 560 while passing through the hole-shaped moving path defined by the moving guide groove H and the first support plate 510 in a curved shape, thereby suppressing damage to the FFC cable 460 during the moving process.

[0155] In a state where the first support plate 510 is disposed at one end of the coupling plate 310, the plurality of support rollers 560 may be disposed in a form extending to one side from the plurality of upper rollers 210. Therefore, during the sliding movement, when the display panel assembly 400 moves between the plurality of upper rollers 210 and the plurality of lower rollers 220 and enters a curved surface defined by the arrangement of the plurality of lower rollers 220, the display panel assembly 400 may be supported while moving between the plurality of support rollers 560 and the plurality of lower rollers 220, so that the display panel assembly 400 may slide stably.

[0156] Hereinafter, a sliding movement process of the display panel assembly 400 in a state where the slidable display device 10 according to an embodiment of the present disclosure is disposed on the roof panel P of a vehicle will be described.

[0157] When electric power is supplied by a power generation component (not illustrated), in a state where the always-on display area 411 is disposed below the roof panel P of the vehicle through the opening P- 2 , the drive motor 340 transmits a driving force to rotate the rotation shaft 330 .

[0158] The carrier 350 is moved in the first direction when the rotation shaft 330 connected to the rotation shaft of the driving motor 340 through the coupling 341 is rotated. In this case, the carrier 350 is moved while being supported by the first LM block LM1.

[0159] When the carrier 350 moves linearly along the first direction, the second transfer bridge B2 integrally connected to the first transfer bridge B1 coupled to the carrier 350 also slides, so that the display panel 410 slides. At the same time, the connection plate 370 mounted on the connection bridge 380 coupled to the carrier 350 also slides along the first direction, so that the display panel 410, the interface board 450 and the FFC cable 460 slide together.

[0160] When the display panel 410 , the interface board 450 , and the FFC cable 460 slide together in the first direction, the plurality of second LM blocks LM2 and the plurality of third LM blocks LM3 slide together or sequentially in a state where the printed circuit board 420 and the cover plate 550 are coupled.

[0161] That is, the plurality of second LM blocks LM2 slide downward along the plurality of second guide rails R2 through the sliding movement of the display panel assembly 400 caused by the linear movement of the carrier 350 .

[0162] When the plurality of second LM blocks LM2 slide in the first direction, the second support plate 520 is caused to slide downward by the sliding movement of the plurality of second LM blocks LM2 while covering one side of the FFC cable 460 .

[0163] When the plurality of second LM blocks LM2 are disposed below the plurality of second guide rails R2, the plurality of third LM blocks LM3 slide downward along the plurality of third guide rails R3.

[0164] When the plurality of third LM blocks LM3 slide in the first direction, the third support plate 530 is caused to slide downward by the sliding movement of the plurality of third LM blocks LM3 while covering one side of the FFC cable 460 .

[0165] That is, in a state where the printed circuit board 420 is connected to the cover plate 550, since the sliding movement is supported by a three-level structure made of a first LM block LM1, a second LM block LM2, and a third LM block LM3 that cooperate with the linear movement of the carrier 350, the display panel assembly 400 can be stably transferred.

[0166] When the always-on display area 411 and the extended display area 412 are moved downward by the sliding movement of the third support plate 530 in a state where multiple third LM blocks LM3 are arranged under multiple third guide rails R3, the carrier 350 can be in contact with one side support block 320, or be arranged at a position adjacent to one side support block 320.

[0167] The position sensor S of a pair of position sensors S arranged at a position corresponding to the one side support block 320 can detect the position of the first LM block LM1 according to the arrangement of the carrier 350, and send the detected position signal related to the first LM block LM1 for stopping the movement of the carrier 350 to the power generation component (not shown).

[0168] When the power generation component (not illustrated) detects that the sliding movement of the display panel assembly 400 in the first direction is completed in response to the received position signal related to the first LM block LM1, the power generation component (not illustrated) can control (turn off) the operation of the driving motor 340 so that the sliding movement of the display panel assembly 400 can be completed.

[0169] In a state where the extended display area 412 is extended through the opening P- 2 and moves downward during the sliding movement process of the display panel assembly 400 , the extended display area 412 may display an image together with the always-on display area 411 .

[0170] Hereinafter, a process in which only the always-on display area 411 is disposed under the roof panel P of the vehicle through the opening P-2 when the display panel assembly 400 is reversely slid will be described.

[0171] When power is supplied again from the power generation part (not illustrated), the driving motor 340 transmits a driving force to rotate the rotating shaft 330 in the reverse direction.

[0172] The carrier 350 is moved in the second direction when the rotation shaft 330 connected to the rotation shaft of the driving motor 340 through the coupling 341 is rotated. In this case, the carrier 350 is moved while being supported by the first LM block LM1.

[0173] When the carrier 350 moves linearly along the second direction, the second transfer bridge B2 integrally connected to the first transfer bridge B1 coupled to the carrier 350 also slides along the second direction, so that the display panel 410 slides along the second direction. At the same time, the connection plate 370 mounted on the connection bridge 380 coupled to the carrier 350 also slides along the second direction, so that the display panel 410, the interface board 450 and the FFC cable 460 slide together.

[0174] The display panel 410 slides upward while being tilted along the second path and then bent and curved along the curved surface caused by the arrangement of the plurality of lower rollers 220, and then the display panel 410 continuously moves in the second direction. In the third path configured to connect the first path and the second path and define the curved surface, the display panel 410 may be supported by the plurality of lower rollers 220, the plurality of supporting rollers 560, and the plurality of upper rollers 210.

[0175] When the display panel 410 , the interface board 450 , and the FFC cable 460 slide together in the second direction, the plurality of second LM blocks LM2 and the plurality of third LM blocks LM3 slide together or sequentially in a state where the printed circuit board 420 and the cover plate 550 are coupled.

[0176] That is, the plurality of third LM blocks LM3 slide upward along the plurality of third guide rails R3 through the sliding movement of the display panel assembly 400 caused by the linear movement of the carrier 350 in the second direction.

[0177] When the plurality of third LM blocks LM3 slide in the second direction, the third support plate 530 is caused to slide upward by the sliding movement of the plurality of third LM blocks LM3 while covering one side of the FFC cable 460 .

[0178] When the plurality of third LM blocks LM3 are disposed above the plurality of third guide rails R3, the plurality of second LM blocks LM2 slide upward along the plurality of second guide rails R2.

[0179] When the plurality of second LM blocks LM2 slide in the second direction, the second support plate 520 is slid upward by the sliding movement of the plurality of second LM blocks LM2 while covering one side of the FFC cable 460 .

[0180] When multiple second LM blocks LM2 are arranged above the multiple second guide rails R2, the multiple second LM blocks LM2, the second support plate 520, the multiple third guide rails R3, the multiple third LM blocks LM3, the third support plate 530, the connecting rod 540, and the cover plate 550 can be arranged on the other side surface of the first support plate 510 while overlapping each other again.

[0181] When only the always-on display area 411 is set under the roof panel P of the vehicle by the sliding movement of the second support plate 520 in a state where multiple second LM blocks LM2 are set above multiple second guide rails R2, the carrier 350 can be in contact with the other side support block 320, or be set at a position adjacent to the other side support block 320.

[0182] The position sensor S of a pair of position sensors S, which is arranged at a position corresponding to the other side support block 320, can detect the position of the first LM block LM1 according to the arrangement of the carrier 350, and send the detected position signal related to the first LM block LM1 for stopping the movement of the carrier 350 to the power generation component (not shown).

[0183] When the power generation component (not illustrated) detects that the sliding movement of the display panel assembly 400 in the second direction is completed in response to the received position signal related to the first LM block LM1, the power generation component (not illustrated) can control (turn off) the operation of the driving motor 340 so that the sliding movement of the display panel assembly 400 can be completed.

[0184] In a state where the extended display area 412 moves upward through the opening P- 2 during the sliding movement process of the display panel assembly 400 , the extended display area 412 may be accommodated in the mounting frame 100 .
