Fig. 3b is a perspective view of a slidable display device according to an embodiment of the present invention. Fig. 4 is a partial cross-sectional view of a slidable display device according to an embodiment of the present invention.

[0028] The structure of a slidable display device 10 according to an embodiment of the present invention will be described with reference to FIGS.

[0029] The slidable display device 10 according to the embodiment of the present invention can be mounted inside the space between the outer shell plate of the vehicle and the roof panel P of the vehicle disposed thereunder.

[0030] The vehicle roof panel P may include a pair of spaced apart support ribs P-1 that protrude downward. The vehicle roof panel P includes an opening P-2 formed in the space between the pair of support ribs P-1.

[0031] The display panel assembly 400 of the slidable display device 10 can be slid to extend into the interior of the vehicle through the opening P-2.

[0032] Although not shown in the drawings, the slidable display device 10 can be applied to other objects with ceilings in addition to the roof panel P of a vehicle.

[0033] The slidable display device 10 includes a mounting frame 100 , a guide member 200 , a panel transport unit 300 , a display panel assembly 400 and a movement support unit 500 .

[0034] The mounting frame 100 can be disposed inside the space between the vehicle's exterior plate and the vehicle's roof panel P disposed thereunder. A guide member 200, a panel transfer unit 300, and a movement support unit 500 are attached to the mounting frame 100.

[0035] The guide member 200 is attached to the inside of the mounting frame 100 and guides the sliding movement of the display panel assembly 400 .

[0036] The panel transport unit 300 slides and moves the display panel assembly 400 while being fixed inside the mounting frame 100 .

[0037] The movement support part 500 is attached to one side end of the mounting frame 100 and is slid together with the display panel assembly 400 to support the sliding movement of the display panel assembly 400 .

[0038] Reference is now made to FIG. 5 for a more detailed description of the mounting frame 100 and guide member 200.

[0039] FIG. 5 is a perspective view of a mounting frame and a guide member of the slidable display device according to the embodiment of the present invention.

[0040] The mounting frame 100 is fixed inside the space between the outer shell plate of the vehicle and the roof panel P of the vehicle disposed thereunder, and forms a frame that defines the outer shape of the slidable display device 10 .

[0041] Referring to FIG. 5, the mounting frame 100 may include a pair of first and second support frames 110 and 120 , a mounting bracket 130 , and a fixing bracket 140 .

[0042] The pair of first support frames 110 may be disposed on both sides of the mounting frame 100. That is, the pair of first support frames 110 may be disposed on both sides of the mounting frame 100 that are perpendicular to the sliding direction of the display panel assembly 400.

[0043] The second support frame 120 is disposed at the ends of the pair of first support frames 121, and can connect and support the pair of first support frames 121.

[0044] A plurality of mounting brackets 130 are fixed to the outer surfaces of the pair of first support frames 110. The mounting brackets 130 may be fixed to the inner surface of an outer shell plate of the vehicle.

[0045] A plurality of fixing brackets 140 are fixed to the inner surfaces of the pair of first support frames 110. The fixing brackets 140 may support the coupling plate 310 of the panel transfer unit 300 by being fixed thereto.

[0046] 3b to 5, the guide member 200 is disposed at one end of the mounting frame 100 to guide the sliding movement of the display panel assembly 400. As shown in FIG.

[0047] 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 roll. The plurality of upper rollers 210 and the plurality of lower rollers 220 are arranged to face each other in the vertical direction. Therefore, the display panel assembly 400 may stably slide between the plurality of upper rollers 210 and the plurality of lower rollers 220.

[0048] A plurality of upper rollers 210 are rotatably coupled to the inner surfaces of the pair of first support frames 110 .

[0049] The plurality of upper rollers 210 rotate due to friction with the display panel assembly 400, which slides in a first direction for extending into the interior of the vehicle through the opening P-2 or a second direction opposite to the first direction, thereby supporting the sliding movement of the display panel assembly 400.

[0050] Considering a pair of upper rollers 210 facing each other among the plurality of upper rollers 210, the pair of upper rollers 210 has a structure in which they are connected in a direction perpendicular to the sliding direction of the display panel assembly 400. Therefore, they contact the surface of the display panel assembly 400 opposite to the surface on which the display panel 410 is provided, thereby stably supporting the sliding movement of the display panel assembly 400.

[0051] The plurality of lower rollers 220 are rotatably coupled to inner surfaces of the pair of first support frames 110. The plurality of lower rollers 220 are disposed below the plurality of upper rollers 210 and together with the plurality of upper rollers 210 form a sliding movement path for the display panel assembly 400.

[0052] Considering a pair of lower rollers 220 facing each other among the plurality of lower rollers 220, the pair of lower rollers 220 supports both sides of the display panel assembly 400, which slides while not being connected to each other, unlike the plurality of upper rollers 210. The pair of lower rollers 220 facing each other are provided in an unconnected form, so that the display panel 410 of the display panel assembly 400 slides while not being hidden by the other side.

[0053] The plurality of lower rollers 220 form a first path extending along a first direction from the lower roller 220 located at the other end, a second path extending along a second direction inclined at an angle of 90° to 130°, preferably 110°, with respect to the first direction, and a third path connecting the first path and the second path to allow the display panel assembly 400 to be transported with a specific curvature between the first path and the second path.

[0054] That is, the plurality of lower rollers 220 extend from the lower roller 220 located at the other end in a direction parallel to the first support frame 110 to form a first path, form a second path extending at an oblique angle from the first path to the end of the mounting frame 100, and include a third path connecting the first path and the second path and arranged in the form of an arc between the first path and the second path.

[0055] If the tilt angle in the second direction of the display panel assembly 400 is inclined at an angle less than 90° along the transport path of the display panel assembly 400, the display panel assembly 400 may bend and stretch excessively, making it difficult to view the images displayed on the display panel 410 and increasing the stress applied to the display panel 410.

[0056] If the tilt angle in the second direction of the transport path of the display panel assembly 400 exceeds 130°, the display panel assembly 400 may be excessively stretched and extended, making it difficult to view the image displayed on the display panel 410, and damage to the moving support part 500 connected to the connecting plate 310 may occur during the sliding movement of the display panel assembly 400.

Fig. 7 is an exploded perspective view of a panel transfer unit of a slidable display device according to an embodiment of the present invention. Fig. 8 is a perspective view of a panel transfer unit of a slidable display device according to an embodiment of the present invention.

Fig. 10 is an exploded perspective view of a display panel assembly of a slidable display device according to an embodiment of the present invention. Fig. 11 is a perspective view of a slidable display device according to an embodiment of the present invention. Fig. 12 is a perspective view of a state in which the display panel assembly of the slidable display device according to an embodiment of the present invention is slid and the display panel is expanded.

[0059] The panel transport unit 300 is attached to the mounting frame 100 and slides the display panel assembly 400 .

[0060] 6 to 9, the panel transfer unit 300 may include a connecting plate 310, a pair of support blocks 320, a rotating shaft 330, a drive motor 340, a carrier 350, a pair of support stands 360, a pair of first guide rails R1, a pair of first LM (Linear Motion) blocks LM1, a first transfer bridge B1, a connecting plate 370, and a connecting bridge 380.

[0061] The coupling plate 310 is fixed to a plurality of fixing brackets 140 arranged on the mounting frame 100. A pair of support blocks 320, a motor support member 342, and a pair of support bases 360 may be fixed to the lower surface of the coupling plate 310.

[0062] The coupling plate 310 includes a movement guide groove H formed at one side end. The movement guide groove H forms a path along which the FFC cable (Flexible Flat Cable) 460 slides due to the first support plate 510 of the movement support unit 500 attached to the coupling plate 310. That is, the movement guide groove H has one side blocked by the first support plate 510 and has a hole shape, forming a path through which the FFC cable 460 passes as it slides due to the movement of the carrier 350.

[0063] The pair of support blocks 320 are fixed to the lower surface of the coupling plate 310. The pair of support blocks 320 are spaced apart from each other along the sliding direction of the display panel assembly 400.

[0064] Bearings are provided inside the pair of support blocks 320. One end and the other end of the rotary shaft 330 are rotatably attached to the bearings provided in the pair of support blocks 320. The pair of bearings fix the rotary shaft 330 in a fixed position without eccentricity. The pair of bearings support the weight of the rotating rotary shaft 330 and the load acting on the rotary shaft 330.

[0065] The rotating shaft 330 can move the carrier 350 in the sliding direction of the display panel assembly 400 through the driving force transmitted by the driving motor 340 .

[0066] The rotating shaft 330 may have the form of a ball screw. The rotating shaft 330 can convert the rotational motion of the driving motor 340 into the linear reciprocating motion of the carrier 350 disposed on the rotating shaft 330. The rotating shaft 330 can be rotated by the driving motor 340 to linearly move the carrier 350 to one side or the other toward the support block 320 on one side or the other side.

[0067] The drive motor 340 is connected to the other of the pair of support blocks 320 and transmits a driving force to the rotation shaft 330 .

[0068] The driving motor 340 is connected to the rotating shaft 330 through a coupler 341. The coupler 341 holds the rotating shaft 330 so that it rotates in a fixed axial direction even if the rotating shaft 330 becomes misaligned during the movement of the carrier 350.

[0069] The drive motor 340 may be supported by a motor support member 342 that is connected to the other support block 320 and disposed between the drive motor 340 and the coupler 341. The motor support member 342 is fixed to the lower surface of the other end of the coupling plate 310.

[0070] The driving motor 340 may be connected to a power generator (not shown) such as an external power source or an internal battery to receive power from the driving motor 340. The driving motor 340 generates a rotational force and transmits the rotational force to the rotation shaft 330 having a ball screw shape.

[0071] The drive motor 340 can rotate the rotary shaft 330 according to the position of the first LM block LM1 received from a pair of position sensors S to a power generation unit (not shown).

[0072] The carrier 350 is disposed on the rotation shaft 330 and may be moved linearly in the sliding direction of the display panel assembly 400 by a driving force transmitted by the driving motor 340. The carrier 350 may be moved linearly back and forth in a first direction extending into the interior of the vehicle through the opening P-2, or in a second direction opposite to the first direction, among the moving directions of the display panel assembly 400.

[0073] The pair of support bases 360 may be disposed on both sides of the pair of support blocks 320. The pair of support bases 360 may be fixed to the lower surface of the coupling plate 310 along the direction of movement of the carrier 350.

[0074] A pair of position sensors S may be spaced apart from one another on the pair of support bases 360. The pair of position sensors S may be disposed at portions of the support base 360 ​​corresponding to the positions where the pair of support blocks 320 are disposed.

[0075] The pair of position sensors S can sense the position of the first LM block LM1 which is moved together with the carrier 350. The pair of position sensors S can transmit a position signal of the sensed first LM block LM1 to a power supply generating unit (not shown).

[0076] The pair of position sensors S may be provided in the form of limit sensors that detect the position of the first LM block LM1 and thereby limit the movement of the carrier 350. The pair of position sensors S limit the movement of the carrier 350, thereby preventing damage or breakage of the panel transfer unit 300 and the generation of noise.

[0077] The power supply generating unit (not shown) can control (ON / OFF) the driving of the driving motor 340 according to the position signal of the received first LM block LM1. The power supply generating unit (not shown) can control the driving motor 340 to rotate the rotating shaft 330 according to the position signal of the received first LM block LM1.

[0078] The panel transport unit 300 may include a Linear Motion Guide (LM Guide) LMG1 to support smooth sliding movement of the display panel assembly 400.

[0079] The LM guide LMG1 includes a pair of first guide rails R1 and a pair of first LM blocks LM1.

[0080] The pair of first guide rails R1 are disposed on and fixed to the lower surfaces of the pair of support bases 360, respectively.

[0081] The pair of first LM blocks LM1 are movably disposed on the pair of first guide rails R1. The pair of first LM blocks LM1 are connected to the carrier 350 via a first transfer bridge B1 (see FIG. 8). Therefore, the pair of first LM blocks LM1 are linked to the movement of the carrier 350. That is, when the carrier 350 moves back and forth in the first or second direction, the pair of first LM blocks LM1 connected to the carrier 350 via the first transfer bridge B1 also moves back and forth in the first or second direction together with the carrier 350 along the pair of first guide rails R1.

[0082] The first transfer bridge B1 is coupled to the lower surfaces of the carrier 350 and the pair of first LM blocks LM1 to connect the carrier 350 and the pair of first LM blocks LM1.

[0083] The first transfer bridge B1 is also connected to the second transfer bridge B2 of the display panel assembly 400. Therefore, as the carrier 350 moves back and forth, the pair of first LM blocks LM1 as well as the display panel 410 of the display panel assembly 400 can be slid.

[0084] The connection plate 370 may be coupled to a connection bridge 380 disposed on the carrier 350. An interface board 450 of the display panel assembly 400 is attached to the connection plate 370 and may move to one side along with the movement of the carrier 350. Therefore, when the carrier 350 moves back and forth in the first or second direction, the pair of first LM blocks LM1 also move back and forth, and the second transfer bridge B2 connected to the first transfer bridge B1 coupled to the lower surfaces of the carrier 350 and the pair of first LM blocks LM1 also move back and forth.

[0085] The display panel 410 of the display panel assembly 400 slides in the first or second direction in conjunction with the carrier 350 and the pair of first LM blocks LM1 as the second transfer bridge B2 is integrally connected to the first transfer bridge B1.

[0086] The interface board 450 of the display panel assembly 400 is disposed on a connecting plate 370 coupled to a connecting bridge 380, and is slidable in the first or second direction together with the display panel 410 due to the reciprocating movement of the carrier 350 simultaneously with the movement of the display panel 410.

[0087] That is, when the driving motor 340 is driven to rotate the rotating shaft 330, the carrier 350 moves back and forth linearly in the first or second direction, and the interface board 450 arranged on the connecting plate 370 and the display panel 410 connected together through the first and second transfer bridges B1 and B2 are also linked to the carrier 350 and slide in the first or second direction simultaneously with the movement of the carrier 350.

[0088] As the display panel 410 and the interface board 450 slide simultaneously, the display panel assembly 400 slides in the first or second direction, and as the display panel assembly 400 slides, the movable support part 500 also covers the display panel assembly 400 and slides in the first or second direction.

[0089] The display panel assembly 400 may be slidably mounted to the mounting frame 100 .

[0090] 9 to 12, the display panel assembly 400 may include a display panel 410, a printed circuit board 420, a mid-cover 430, a plurality of back bars 440, an interface board 450, an FFC cable 460, a second transfer bridge B2, and a dummy panel 470.

[0091] The display panel 410 is slidable downward through the opening P-2.

[0092] The display panel 410 may include display elements for displaying images, driving elements for driving the display elements, wiring for transmitting various signals to the display elements and driving elements, etc. The display panel 410 is generally disposed parallel to the binding plate 310, and when extending downward through the opening P-2, it is moved so as to tilt in a direction different from that of the binding plate 310. When the display panel 410 is moved so as to tilt, the display panel 410 must bend in a curved shape during the process of changing direction, so it may have a flexible shape.

[0093] 3b, a display unit DP may be formed on the display panel 410. The display unit DP may include a constant display area 411 and an extended display area 412.

[0094] The constant display area 411 is provided in the form of an Always-on Display, and is an area of ​​the display unit DP that is kept pulled downward through the opening P-2. Therefore, the constant display area 411 can be used as an area that can always display a screen, and information such as the date, weather, time, and news can be displayed in the constant display area 411. However, without being limited thereto, the constant display area 411 does not have to display a screen in the off state.

[0095] A printed circuit board 420 may be disposed on one side of the constant display area 411 to drive the display unit DP.

[0096] When the extended display area 412 is slid downward through the opening P-2, the mid cover 430, the plurality of back bars 440, and the dummy panel 470 are also slid downward through the opening P-2.

[0097] When the extended display area 412 is moved, images can be displayed in the extended display area 412 and the constant display area 411 together or separately.

[0098] The printed circuit board 420 is electrically connected to an edge of the display panel 410.

A timing controller or a power supply unit is disposed on the printed circuit board 420, and the printed circuit board 420 can be driven to display images in the constant display area 411 and the extended display area 412. The printed circuit board 420 may have the form of a source printed circuit board (S-PCB) on which a data driver is mounted.

[0099] The mid 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 mid cover 430 may have a larger area than the display panel 410 so as to protect the display panel 410 from external impact.

[0100] The mid cover 430 may include a ductile material so that deformation does not occur even when the display panel assembly 400 is repeatedly slid. Specifically, the mid cover 430 may include a material such that the stress applied to the mid cover 430 when the display panel 410 slides along the guide member 200 is equal to or less than the yield stress of the mid cover 430. The mid cover 430 may include materials such as metal, rubber, plastic, or fabric. However, the material of the mid cover 430 may be variously changed as long as it satisfies physical property conditions such as thermal deformation amount, radius of curvature, or rigidity depending on the design, and is not limited thereto.

[0101] The mid cover 430 may have a thin thickness so that deformation does not occur even when the display panel assembly 400 is repeatedly slid.

[0102] The mid cover 430 includes a plurality of openings. The mid cover 430 may include a pattern in which a plurality of openings each having a hole shape are repeatedly arranged. For example, the plurality of openings may have various shapes, such as, but not limited to, an oval shape, a polygonal shape, etc. The plurality of openings may be flexibly deformed, so that even if stress is applied to the display panel assembly 400 due to repeated sliding of the display panel assembly 400, the stress applied to the mid cover 430 may be minimized.

[0103] Between the mid cover 430 and the display panel 410, a first adhesive layer AD1 is disposed.

[0104] The first adhesive layer AD1 can bond the mid cover 430 and the display panel 410. The first adhesive layer AD1 is made of an adhesive material and can include a thermosetting or natural curing adhesive. The first adhesive layer AD1 can include, but is not limited to, an OCA (Optical Clear Adhesive) or a PSA (Pressure Sensitive Adhesive).

[0105] A plurality of back bars 440 may be disposed on one surface of the mid cover 430 .

[0106] The plurality of back bars 440 support the display panel 410 and the mid cover 430. The thickness of the plurality of back bars 440 may be thicker than the thickness of the mid cover 430, and can protect the display panel 410 and the mid cover 430 from external impact.

[0107] The back bars 440 may include a rigid material. The back bars 440 may include a metal such as SUS (Steel Use Stainless) or Invar, or a plastic material. However, the material of the back bars 440 may be variously changed depending on the design as long as it satisfies physical property conditions such as thermal deformation amount, curvature radius, rigidity, etc., and is not limited thereto.

[0108] A second adhesive layer AD2 is disposed between the plurality of back bars 440 and the mid cover 430.

[0109] The second adhesive layer AD2 can bond the mid cover 430 and the plurality of back bars 440. The second adhesive layer AD2 is made of an adhesive material and may include an elastic material. The second adhesive layer AD2 may include, but is not limited to, a foam pad and an elastic resin.

[0110] The interface board 450 is connected to the printed circuit board 420 so that an image can be displayed on the display unit DP. The interface board 450 may be connected to an image control unit so that the interface board 450 can control an image displayed on the display unit DP while receiving power. The interface board 450 may be connected to the printed circuit board 420 through an FFC cable 460.

[0111] The interface board 450 is attached to a connection plate 370 coupled to a connection bridge 380 coupled to the carrier 350. The interface board 450 slides in a first or second direction as the connection plate 370 moves in accordance with the movement of the carrier 350. The interface board 450 slides in the first or second direction simultaneously with the second transfer bridge B2 of the mid cover 430, which is integrally coupled to the first transfer bridge B1, as the carrier 350 moves. The interface board 450 slides in the first or second direction above the coupling plate 310 while remaining in a state of moving only above the mounting frame 100.

[0112] 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 to exchange data, signals, or power for displaying images on the display unit DP. The FFC cable 460 may include a flexible material. The FFC cable 460 is moved in a first or second direction by movement of the connection plate 370 connected to the connection bridge 380 simultaneously with movement of the display panel 410 through the first moving bridge B1. When moving in the first or second direction, the FFC cable 460 passes through the movement guide groove H of the connection plate 310 in a curved shape and moves downward (first direction) or upward (second direction), sliding along the second support plate 520 and the third support plate 530 of the movement support unit 500.

[0113] The second transfer bridge B2 is disposed at the upper end of the mid 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, which is integrally coupled to the first transfer bridge B1, moves the mid cover 430 in the first or second direction simultaneously with the movement of the carrier 350 in the first or second direction driven by the driving motor 340, so that the display panel 410 extends downward or slides upward through the opening P-2 to be accommodated inside the mounting frame 100.

[0114] The dummy panel 470 may be disposed at an upper end of the display panel 410, which is opposite to the lower end of the display panel 410 where the printed circuit board 420 is disposed. The dummy panel 470 is disposed at the upper end of the display panel 410, thereby ensuring a specific length so that the constant display area 411 of the display panel 410, which has a certain length, can be normally maintained in a state of extending downward through the opening P-2 so that it can be utilized in the form of Always On Display.

[0115] 13 to 15 are also referred to below for a detailed description of the moving support 500. FIG.

[0116] Fig. 13 is a perspective view of a movable support part of a slidable display device according to an embodiment of the present invention. Fig. 14 is a perspective view of a state in which the movable support part of a slidable display device according to an embodiment of the present invention is expanded downward by sliding of a display panel assembly. Fig. 15 is an exploded perspective view of a movable support part of a slidable display device according to an embodiment of the present invention.

[0117] The movable support part 500 may be disposed at one end of the mounting frame 100. The movable support part 500 is connected to the display panel assembly 400 and covers and supports the display panel assembly 400 on one side. The movable support part 500 may extend downward as the display panel assembly 400 slides.

[0118] 13 to 15, the movable support part 500 may include a first support plate 510, a plurality of second guide rails R2, a plurality of second LM blocks LM2, a second support plate 520, a plurality of third guide rails R3, a plurality of third LM blocks LM3, a third support plate 530, a connecting bar 540, and a cover plate 550.

[0119] The first support plate 510 may be coupled to one side end of the connecting plate 310 fixed to the fixing bracket 140 of the mounting frame 100. The first support plate 510 covers the display panel assembly 400 accommodated inside the mounting frame 100 and supports the load of the plurality of second guide rails R2, the plurality of second LM blocks LM2, the second support plate 520, the plurality of third guide rails R3, the plurality of third LM blocks LM3, the third support plate 530, the connecting bar 540, and the cover plate 550.

[0120] On the other side of the first support plate 510, a plurality of second guide rails R2, a plurality of second LM blocks LM2, a second support plate 520, a plurality of third guide rails R3, a plurality of third LM blocks LM3, a third support plate 530, a connecting bar 540 and a cover plate 550 may be arranged overlapping each other, with the arrangement of the constant display area 411 maintained under the vehicle roof panel P.

[0121] The movable support unit 500 may include one or more LM guides to support smooth sliding movement of the second support plate 520 and the third support plate 530, which are slid obliquely upward or downward in accordance with the sliding movement of the display panel assembly 400. The LM guide has a form including a guide rail and an LM block.

[0122] In the slidable display device 10 according to the embodiment of the present invention, the movement support part 500 may be provided with a second LM guide LMG2 and a third LM guide LMG3.

[0123] The second LM guide LMG2 includes a plurality of second guide rails R2 and a plurality of second LM blocks LM2. When the carrier 350 is moved in the first direction or the second direction by the driving motor 340, the second LM guide LMG2 slides the second support plate 520 downward (first direction) or upward (second direction).

[0124] A plurality of second guide rails R2 are disposed on the other side of the first support plate 510.

[0125] The second LM blocks LM2 are respectively arranged on the second guide rails R2 and can slide when the carrier 350 is moved in the first or second direction by the driving motor 340, causing the second LM blocks LM2 to slide and move the second support plate 520 upward or downward.

[0126] The second support plate 520 is coupled to the other side of the plurality of second LM blocks LM2, and is slid in the first direction or the second direction by the sliding movement of the plurality of second LM blocks LM2.

[0127] The second support plate 520 moves together with the coupled printed circuit board 420 and cover plate 550. That is, the second support plate 520 can move together with the display panel assembly 400 due to the sliding movement of the display panel assembly 400, which moves the display panel 410 and the interface board 450 in the first or second direction as the carrier 350 slides.

[0128] The second support plate 520 covers one side of the FFC cable 460, which moves as the interface board 450 moves in the first or second direction, to form a movement path for the FFC cable 460. The second support plate 520 restricts the movement path of the FFC cable 460 to the inside of guide ribs formed on both sides. The FFC cable 460 moves in the first or second direction due to the movement of the display panel 410 through 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 or second direction, it moves downward or upward while passing through the movement guide groove H of the connection plate 310 in a curved shape, and slides along the second support plate 520 in the first or second direction.

[0129] The third LM guide LMG3 includes a plurality of third guide rails R3 and a plurality of third LM blocks LM3. When the carrier 350 is moved in the first direction or the second direction by the driving motor 340, the third LM guide LMG3 causes the third support plate 530 to slide downward (first direction) or upward (second direction).

[0130] A plurality of third guide rails R3 are disposed on the other side of the second support plate 520.

[0131] The third LM blocks LM3 are respectively arranged on the third guide rails R3 and can slide when the carrier 350 is moved in the first or second direction by the driving motor 340, causing the third support plate 530 to move upward or downward.

[0132] The third support plate 530 is coupled to the other side of the plurality of third LM blocks LM3, and is slid in the first direction or the second direction by the sliding movement of the plurality of third LM blocks LM3.

[0133] The third support plate 530 moves together with the coupled printed circuit board 420 and cover plate 550. That is, the display panel 410 and the interface board 450 can be moved together with the display panel assembly 400 by the sliding movement of the display panel assembly 400, which is moved in the first or second direction by the sliding movement of the carrier 350.

[0134] The third support plate 530 covers one side of the FFC cable 460, which moves with the movement of the interface board 450 in the first or second direction, to form a movement path for the FFC cable 460. The FFC cable 460 moves in the first or second direction due to the movement of the display panel 410 through 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 or second direction, it moves downward or upward while passing through the movement guide groove H of the connection plate 310 in a curved shape, and then slides along the third support plate 530 via the second support plate 520 in the first or second direction.

[0135] The cover plate 550 is coupled to one or more connecting bars 540 disposed on the third support plate 530 to cover the printed circuit board 420. The cover plate 550 may be disposed on the printed circuit board 420. Specifically, the cover plate 550 may cover the printed circuit board 420 in a form attached to an end of the mid cover 430 disposed on the printed circuit board 420.

[0136] The moving support part 500 of the slidable display device 10 according to the embodiment of the present invention may further include a plurality of support rollers 560 .

[0137] The plurality of support rollers 560 may be disposed on both sides of the second guide rail R2 on the other side of the first support plate 510. That is, the plurality of support rollers 560 are disposed across the second guide rail R2 to support the display panel assembly 400 sliding in the first or second direction. Therefore, the FFC cable 460 passes through a curved movement path in the form of a hole formed by the movement guide groove H and the first support plate 510, and moves in the first or second direction along the spaces between the plurality of support rollers 560, preventing damage during the movement process.

[0138] The plurality of support rollers 560 may be arranged in a form extending to one side of the plurality of upper rollers 210, with the first support plate 510 being arranged at one end of the connecting plate 310. Therefore, when the display panel assembly 400 passes between the plurality of upper rollers 210 and the plurality of lower rollers 220 and enters a curved surface formed by the arrangement of the plurality of lower rollers 220 during sliding movement, it is supported by passing between the plurality of support rollers 560 and the plurality of lower rollers 220, and can slide stably.

[0139] Hereinafter, a sliding movement process of the display panel assembly 400 in a state where the slidable display device 10 according to the embodiment of the present invention is disposed on the roof panel P of the vehicle will be described.

[0140] When power is supplied from a power generation unit (not shown), the drive motor 340 transmits driving force so that the rotating shaft 330 rotates with the constant display area 411 positioned under the vehicle roof panel P through the opening P-2.

[0141] When the rotary shaft 330 connected to the rotary shaft of the driving motor 340 through the coupler 341 rotates, the carrier 350 moves in the first direction. At this time, the carrier 350 is supported and moved by the first LM block LM1.

[0142] When the carrier 350 moves linearly in the first direction, the second transfer bridge B2, which is integrally connected to the first transfer bridge B1 connected to the carrier 350, also slides, causing the display panel 410 to slide. At the same time, the connection plate 370 attached to the connection bridge 380 connected to the carrier 350 also slides in the first direction, causing the display panel 410, interface board 450, and FFC cable 460 to slide together.

[0143] When the display panel 410, the interface board 450, and the FFC cable 460 all slide in the first direction, the plurality of second LM blocks LM2 and the plurality of third LM blocks LM3 slide together or sequentially while the printed circuit board 420 and the cover plate 550 are coupled together.

[0144] That is, the plurality of second LM blocks LM2 are slid downward along the plurality of second guide rails R2 by the sliding movement of the display panel assembly 400 caused by the linear movement of the carrier 350.

[0145] When the plurality of second LM blocks LM2 slide in the first direction, the second support plate 520 covers the FFC cable 460 on one side and slides downward due to the sliding movement of the plurality of second LM blocks LM2.

[0146] When the second LM blocks LM2 are arranged below the second guide rails R2, the third LM blocks LM3 are slid downward along the third guide rails R3.

[0147] When the plurality of third LM blocks LM3 slide in the first direction, the third support plate 530 covers the FFC cable 460 on one side and slides downward due to the sliding movement of the plurality of third LM blocks LM3.

[0148] That is, with the printed circuit board 420 and the cover plate 550 coupled together, the display panel assembly 400 can be stably transported since its sliding movement is supported by a three-stage structure including the first LM block LM1, the second LM block LM2, and the third LM block LM3, which are linked to the linear movement of the carrier 350.

[0149] With the plurality of third LM blocks LM3 positioned below the plurality of third guide rails R3, when the third support plate 530 slides to move the constant display area 411 and the extended display area 412 downward, the carrier 350 may be positioned in contact with or adjacent to one of the support blocks 320.

[0150] Of the pair of position sensors S, the position sensor S arranged at a position corresponding to one of the support blocks 320 can detect the position of the first LM block LM1 according to the arrangement of the carrier 350 and transmit the detected position signal of the first LM block LM1 to a power generation unit (not shown) to stop the movement of the carrier 350.

[0151] The power generation unit (not shown) can detect that the sliding movement of the display panel assembly 400 in the first direction has been completed based on the position signal of the received first LM block LM1, and control (OFF) the driving of the driving motor 340, thereby completing the sliding movement of the display panel assembly 400.

[0152] The extended display area 412 extends through the opening P-2 during the sliding movement of the display panel assembly 400 and can display an image together with the constant display area 411 when moved downward.

[0153] The following describes a process in which the display panel assembly 400 is slid in the opposite direction so that only the display area 411 is positioned under the roof panel P of the vehicle through the opening P-2.

[0154] When power is again supplied from the power generating unit (not shown), the driving motor 340 transmits a driving force to the rotating shaft 330 so that the rotating shaft 330 rotates in the opposite direction.

[0155] When the rotary shaft 330 connected to the rotary shaft of the driving motor 340 through the coupler 341 rotates, the carrier 350 moves in the second direction. At this time, the carrier 350 is supported and moved by the first LM block LM1.

[0156] When the carrier 350 moves linearly in the second direction, the second transfer bridge B2, which is integrally connected to the first transfer bridge B1 connected to the carrier 350, also slides in the second direction, causing the display panel 410 to slide in the second direction. At the same time, the connection plate 370 attached to the connection bridge 380 connected to the carrier 350 also slides in the second direction, causing the display panel 410, interface board 450, and FFC cable 460 to slide together.

[0157] The display panel 410 slides upward at an oblique angle along the second path, and then bends and warps along the curved surface formed by the arrangement of the plurality of lower rollers 220, thereby moving continuously in the second direction. The display panel 410 can be supported by the plurality of lower rollers 220, the plurality of support rollers 560, and the plurality of upper rollers 210 on a third path that connects the first path and the second path and forms a curved surface.

[0158] When the display panel 410, the interface board 450, and the FFC cable 460 all slide in the second direction, the plurality of second LM blocks LM2 and the plurality of third LM blocks LM3 slide together or sequentially while the printed circuit board 420 and the cover plate 550 are coupled together.

[0159] That is, the plurality of third LM blocks LM3 are slid upward along the plurality of third guide rails R3 as the display panel assembly 400 slides due to the linear movement of the carrier 350 in the second direction.

[0160] When the plurality of third LM blocks LM3 slide in the second direction, the third support plate 530 covers the FFC cable 460 on one side and slides upward due to the sliding movement of the plurality of third LM blocks LM3.

[0161] When the third LM blocks LM3 are placed on top of the third guide rails R3, the second LM blocks LM2 are slid upward along the second guide rails R2.

[0162] When the plurality of second LM blocks LM2 begin to slide in the second direction, the second support plate 520 covers the FFC cable 460 on one side and slides upward due to the sliding movement of the plurality of second LM blocks LM2.

[0163] When the plurality of second LM blocks LM2 are disposed on the upper portions of the plurality of second guide rails R2, the plurality of second LM blocks LM2, the second support plate 520, the plurality of third guide rails R3, the plurality of third LM blocks LM3, the third support plate 530, the connecting bar 540, and the cover plate 550 may also be disposed in an overlapping state on the other side of the first support plate 510.

[0164] With the plurality of second LM blocks LM2 positioned on top of the plurality of second guide rails R2, when the second support plate 520 is slid to position only the constant display area 411 under the roof panel P of the vehicle, the carrier 350 can be positioned in contact with or adjacent to the support block 320 on the other side.

[0165] The position sensor S, which is arranged at a position corresponding to the other support block 320 of the pair of position sensors S, can sense the position of the first LM block LM1 according to the arrangement of the carrier 350 and transmit the sensed position signal of the first LM block LM1 to a power generation unit (not shown) to stop the movement of the carrier 350.

[0166] The power generation unit (not shown) can detect that the sliding movement of the display panel assembly 400 in the second direction has been completed based on the position signal of the received first LM block LM1, and control (OFF) the driving of the driving motor 340, thereby completing the sliding movement of the display panel assembly 400.

[0167] The extended display area 412 can be accommodated inside the mounting frame 100 while being moved upward through the opening P-2 during the sliding movement of the display panel assembly 400.
