[0031] Large LED displays are generally used for large-area display and projection. Their sizes are generally large, and the overall display screen usually needs to be realized by splicing multiple single display panels. It is relatively difficult to achieve curved display for such large-area LED displays. In the prior art, after multiple mounting plates are rotatably connected, the display screens are mounted on the mounting plates one by one, so that the overall display screen visually appears to be bent; however, the screen itself is not actually bent, and the bending angles between multiple mounting plates are relatively limited, resulting in a low degree of freedom for adjusting the overall angle of the screen.

[0032] The present invention proposes a flexible and bendable LED display screen 100.

[0033] Please refer to Figures 1-9In one embodiment of the present invention, the flexible bendable LED display screen 100 includes: a frame assembly 1, a support assembly 3 and an LED display screen 4; the frame assembly 1 includes a first frame 11 and a second frame 12, and the second frame 12 is rotatably connected to the first frame 11 through a connecting mechanism 2; the support assembly 3 is arranged on one side of the frame assembly 1, and the first frame 11 and the second frame 12 change the shape of the support assembly 3 through relative rotation; the LED display screen 4 is arranged on the side of the support assembly 3 away from the frame assembly 1, and the LED display screen 4 can bend as the shape of the support assembly 3 changes.

[0034] In this embodiment, the frame assembly 1 is a supporting structure of the flexible and bendable LED display screen 100, and the frame assembly 1 includes a first frame 11 and a second frame 12. Among them, the first frame 11 is the main supporting structure, and the overall strength is relatively high. In addition to being used to support the second frame 12, the first frame 11 also has an installation cavity for installing circuit elements. The circuit elements are used to realize the circuit control function of the flexible and bendable LED display screen 100, so that operations such as controlling screen display or angle adjustment can be performed autonomously according to a preset method; after the circuit elements are arranged in the installation cavity, the opening of the installation cavity is covered by the cover body so that the circuit elements are installed in the installation cavity without falling out, and dust is prevented from entering and damaging the operation of the circuit elements. The second frame 12 is set to a structure with a hollow middle and a high outer contour strength, so that the second frame 12 is light in weight, so that it can be flexibly rotated on the first frame 11, and at the same time, it has a certain strength to cooperate with the first frame 11 to fix the support assembly 3. The first frame 11 and the second frame 12 are rotatably connected by the connecting mechanism 2. One end of the connecting mechanism 2 is fixedly installed on the first frame 11 by a threaded fastener, and the other end is fixedly installed on the second frame 12 by a threaded fastener, so that each structure is easy to disassemble and maintain. At the same time, each structure is connected by a threaded fastener. The frame assembly 1 can be first split into multiple structures for transportation, and then transported to a suitable location for installation to reduce transportation costs. In this embodiment, the LED display screen 4 uses a flexible material as a substrate, so that the screen itself can be bent, folded or stretched to adapt to a variety of installation surfaces and shapes; the support assembly 3 is used to transform different curved surfaces and shapes through permutations and combinations and its own bending, so that the LED display screen 4 installed on its surface shows curved surfaces of different angles and shapes as the surface shape of the support assembly 3 changes.

[0035] In this embodiment, specifically, two second frames 12 are provided. The two second frames 12 are respectively rotatably connected to both ends of the first frame 11. The two second frames 12 are respectively rotatably connected to both sides of the first frame 11 through connecting members, enabling the frame assembly 1 to rotate at a larger angle, and enabling the flexible curved LED display screen 100 to be adjusted into curved surfaces of more shapes through one frame assembly 1. In other embodiments, when the flexible curved LED display screen 100 does not need to be adjusted into a too complex curved surface, only one second frame 12 may be provided and rotatably connected to the first frame 11 to reduce the overall mass of the flexible curved LED display screen 100. After the frame assembly 1 is assembled, the support assembly 3 is installed on one side of the frame assembly 1. The side of the support assembly 3 facing away from the frame assembly 1 is a planar structure, and the LED display screen 4 can be flattened when installed on this side. The support assembly 3 can change the curved surface shape of the outer surface along with the rotation of the second frame 12 relative to the first frame 11 in the frame assembly 1, so that the flexible LED display screen 4 presents different curved surface shapes along with the shape of the outer surface of the support assembly 3. Refer to Figures 8-9 , Figures 8-9 which are two of the forms for splicing multiple flexible curved LED display screens 100. When the screen display area of a single flexible curved LED display screen 100 is not sufficient, multiple flexible curved LED display screens 100 can be arranged and combined as required, so that the display interfaces of multiple LED display screens 4 are sequentially connected to form a large display interface. At the same time, multiple flexible curved LED display screens 100 can be bent as required by themselves, and multiple flexible curved LED display screens 100 can be fixed on the building surface or a preset rack on the site after being spliced at different angles, thereby forming a large LED curved display screen that can flexibly change the curved surface shape.

[0036] The technical solution of the present invention is to adopt a frame assembly 1 provided in the flexible curved LED display screen 100 and a support assembly 3 provided on one side of the frame assembly 1. By providing a first frame 11 and a second frame 12 in the frame assembly 1 and connecting the first frame 11 and the second frame 12 through a connection mechanism 2, the first frame 11 and the second frame 12 can rotate relative to each other, thereby changing the form of the support assembly 3. The support assembly 3 can drive the LED display screen 4 installed on one side of the support assembly 3 to bend as required. The flexible curved LED display screen 100 can achieve stepless adjustment of the LED display screen 4 through the connection mechanism 2, making the bending degree adjustment of the flexible curved LED display screen 100 more flexible.

[0037] In one embodiment, the frame assembly 1 has two second frames 12, and the two second frames 12 are relatively arranged at two ends of the first frame 11. In this embodiment, the two second frames 12 can rotate toward the same side relative to the first frame 11, so that the LED display screen 4 forms an arc structure that is concave or convex toward the side away from the frame assembly 1, and the two second frames 12 can also rotate toward the opposite side relative to the first frame 11, so that the LED display screen 4 forms an S-shaped curved surface.

[0038] See also Figure 3 , 4 In one embodiment, the support assembly 3 includes: a connecting piece 31 and a plurality of mounting plates 32; the connecting piece 31 is installed on one side of the frame assembly 1, the connecting piece 31 is extended along the first direction, the connecting piece 31 is fixedly connected to the first frame 11 and the second frame 12, and when the second frame 12 rotates relative to the first frame 11, the connecting piece 31 can bend along the rotation direction of the second frame 12 relative to the first frame 11; the plurality of mounting plates 32 are used to install the LED display screen 4, the mounting plate 32 is installed on the side of the connecting piece 31 away from the frame assembly 1, the mounting plate 32 is extended along the second direction, the plurality of mounting plates 32 are arranged along the first direction, the plurality of mounting plates 32 are installed on the frame assembly 1 through the connecting piece 31, and the first direction intersects with the second direction. In this embodiment, the first direction is the horizontal direction, and the second direction is the vertical direction. The connecting piece 31 is a flat and long strip metal sheet, which is extended in the horizontal direction. The length of the strip metal sheet is greater than or equal to the horizontal width of the frame assembly 1, so that when the strip metal sheet is installed on the frame assembly 1, its length can reach both ends of the frame assembly 1, and the middle section of the strip metal sheet can be fixed to the first frame 11, and the two ends can be fixed to the second frame 12, so that it can be connected and fixed to both the first frame 11 and the second frame 12 at the same time. In this way, when the second frame 12 rotates relative to the first frame 11, the two ends of the strip metal sheet can deflect relative to the middle section under the action of the second frame 12, thereby forming a curved shape. In other embodiments, when only one second frame 12 is provided to be rotatably connected to the first frame 11, the two ends of the mounting strip are respectively connected to the first frame 11 and the second frame 12, and the mounting strip can only be bent into an arc structure, and does not form an S-shaped structure. The mounting plate 32 is arranged in the vertical direction. The mounting plate 32 is a relatively hard metal plate that is not easy to bend. A plurality of mounting plates 32 are arranged along the extension direction of the mounting strip and are connected and fixed to the mounting strip by fasteners. When the mounting strip is bent, the plurality of mounting plates 32 are arranged along the curve of the mounting strip, and finally drive the LED display screen 4 to bend to form a preset curved surface.

[0039] In one embodiment, the connecting piece 31 is provided with a plurality of mounting positions for mounting the mounting plate 32 along a first direction, and the plurality of mounting plates 32 are mounted on the mounting positions one by one; two mounting holes 311 for the fasteners to pass through are formed in each mounting position, and the two mounting holes 311 are spaced along the first direction; the connecting piece 31 is provided with a plurality of strips spaced along a second direction. The mounting holes 311 are strip-shaped, and the strip-shaped holes extend along the length direction of the connecting piece 31. Since the connecting piece 31 will be stressed to form an arc structure when bent, the outer side of the annular structure is stressed and stretched, and the inner side of the arc is stressed and compressed. The plurality of mounting plates 32 arranged closely in the straight state of the connecting piece 31 will be displaced due to the stretching or compression of the connecting piece 31 when the connecting piece 31 is bent. Therefore, the mounting holes 311 are arranged in a strip shape, so that when the mounting plate 32 is mounted on the connecting piece 31 through the fasteners passing through the mounting holes 311, there is a certain space for the mounting plate 32 to be adjusted, avoiding the mounting plate 32 from being damaged due to stretching or extrusion when the connecting piece 31 is bent. In this embodiment, each mounting plate 32 is mounted on the connecting piece 31 through a set of mounting holes 311, and each set of mounting holes 311 has two mounting holes 311. Each mounting plate 32 is fixed to the connecting piece 31 through two mounting holes 311 at the same time, so as to better control the angle of the mounting plate 32, so that the curve of the finally presented flexible bendable LED display screen 100 is smoother. The number of mounting holes 311 in the set of mounting holes 311 can also be increased or decreased according to the quality of the mounting plate 32 or the curvature requirement of the flexible bendable LED display screen 100 to adapt to flexible bendable LED display screens 100 with different requirements. In this embodiment, the connecting piece 31 is provided with four strips spaced along the second direction, and the mounting plates 32 are arranged in two rows along the second direction. A plurality of mounting plates 32 are arranged along the extending direction of the connecting piece 31 in each row of mounting plates 32, and each row of mounting plates 32 is respectively connected to every two connecting pieces 31, so that while the mounting plates 32 are mounted more stably, the display area of the flexible bendable LED display screen 100 is larger. The number of the strips, the length, the arrangement number of the mounting plates 32, and the number of rows can all be increased or decreased according to needs.

[0040] Please refer to Figure 1 、 56. In one embodiment, the connection mechanism 2 includes a connection shaft 22 and two connection components 21. The two connection components 21 are arranged opposite to each other along the second direction. The two connection components 21 are synchronously connected through the connection shaft 22 so that the two connection components 21 move synchronously. The connection mechanism 2 is provided with two connection components 21. The two connection components 21 are arranged at intervals along the height direction to balance the center of gravity of the flexible and bendable LED display screen 100, so that the movement of the flexible and bendable LED display screen 100 is more stable. The two connection components 21 can be linked through the connection shaft 22, so that the connection mechanism 2 can drive the structure of the two connection components 21 to adjust at the same time through only one connection shaft 22, and the two connection components 21 rotate at the same angle, thereby driving the second frame 12 to rotate only, and will not tilt due to the inconsistent rotation angles of the two connection components 21. In other embodiments, the number of connection components 21 can also be increased or decreased according to the actual weight of the flexible and bendable LED display screen 100. It is only necessary for multiple connection components 21 to be transmission-connected to the same connection shaft 22 to achieve the synchronous adjustment of multiple connection components 21.

[0041] See also Figure 1 , 5 6. In one embodiment, the connection assembly 21 includes a first connection member 211 and a second connection member 212, and the first connection member 211 and the second connection member 212 are rotatably connected; one end of the first connection member 211 away from the second connection member 212 is connected to the first frame 11, and one end of the second connection member 212 away from the first connection member 211 is connected to the second frame 12. The first connection member 211 is fixedly connected to the first frame 11 by a threaded fastener, and the second connection member 212 is fixedly connected to the second frame 12 by a threaded fastener. The first connection member 211 and the second connection member 212 rotate relative to each other, so that the first frame 11 connected to the first connection member 211 and the second frame 12 connected to the second connection member 212 rotate relative to each other, thereby changing the final angle of the first frame 11 and the second frame 12. When at least two connection assemblies 21 are arranged at intervals along the second direction, a connecting metal plate or metal rod for transmission can also be arranged between two adjacent first connection members 211 or second connection members 212, so that the structure of multiple connection assemblies 21 that need to move synchronously is more stable when moving.

[0042] See also Figure 6 , 7, in one embodiment, the first connecting member 211 and the second connecting member 212 are arranged at intervals in the second direction. A first sliding groove 212a is formed on one side of the second connecting member 212 close to the first connecting member 211. The first sliding groove 212a extends in an arc shape along the rotation direction of the second frame 12 relative to the first frame 11; a limiting post 211a is provided on one side of the first connecting member 211 close to the second connecting member 212, and the limiting post 211a is slidably arranged in the first sliding groove 212a. In this embodiment, the movement track of the limiting post 211a in the limiting groove is arc-shaped, and the circle where the arc is located is set as the first base circle; two first sliding grooves 212a are formed on the second connecting member 212, and the two first sliding grooves 212a are arranged at intervals along the rotation direction on the first base circle. The normal line of the first base circle is the base axis around which the second connecting member 212 rotates, and the two first sliding grooves 212a extend along the same radian and are coaxially arranged on the circumference of the base circle. The first connecting member 211 is provided with a limiting post 211a corresponding to the first sliding groove 212a. The limiting post 211a is cylindrical, and the cross-sectional diameter of the cylinder is adapted to the width of the first sliding groove 212a, so that the limiting post 211a can slide in the sliding groove along a fixed track, that is, the track of the first base circle, thereby driving the first connecting member 211 and the second connecting member 212 to rotate relatively. The movement track of the limiting post 211a in the first sliding groove 212a is the same as the rotation direction of the second frame 12 relative to the first frame 11.

[0043] In one embodiment, a dial 211b is provided on the side of the first connecting member 211 facing away from the support assembly 3. The dial has a plurality of sawteeth, and the plurality of sawteeth are arranged along the rotation direction of the second frame 12 relative to the first frame 11. The connecting assembly 21 further includes a gear 213 engaged with the sawteeth. The gear 213 is rotatably mounted on the second connecting member 212; the connecting shaft 22 is drivingly connected to the gear 213 to drive the second connecting member 212 to rotate relative to the first connecting member 211 through the gear 213. In this embodiment, a gear 213 groove adapted to the outer diameter of the gear 213 is formed on the side of the second connecting member 212 facing the first connecting member 211. The gear 213 is rotatably mounted in the gear 213 groove. The gear 213 is meshed and connected with the dial 211b. After meshing, the gear 213 rolls on the outer periphery of the dial 211b under the action of an external force. The dial 211b is arc-shaped and provided on the side of the first connecting member 211 facing away from the support assembly 3. The arc extends along the rotation direction of the second frame 12 relative to the first frame 11. At this time, the movement track of the gear 213 on the dial 211b is also arc-shaped. Let the entire circle where the arc is located be the second base circle. Then the normal line of the second base circle coincides with the normal line of the aforementioned first base circle, that is, the second base circle is coaxially arranged with the aforementioned first base circle. Let the normal line of the first base circle and the second base circle be the base axis. Since the gear 213 groove has a limiting effect on the gear 213, the gear 213 can only rotate relative to the second connecting member 212 and cannot displace relative to the second connecting member 212. When the gear 213 rolls along the dial 211b, the gear 213 will rotate and move along the circumferential direction of the second base circle at the same time. Under the limiting effect of the gear 213 groove, the second connecting member 212 will move along the second base circle together with the gear 213. And because the first base circle and the second base circle are coaxially arranged, finally the second connecting member 212 will also rotate around the base axis under the action of the first chute 212a and the limiting post 211a, so as to drive the second frame 12 to rotate relative to the first frame 11.

[0044] In this embodiment, the connecting shaft 22 is drivingly connected to the gear 213. By rotating the connecting shaft 22, the gear 213 can be driven to rotate. Under the action of the sawteeth, the gear 213 rolls along the dial 211b. Under the combined action of the gear 213 and the limiting post 211a, the second connecting member 212 rotates relative to the first connecting member 211 around the base axis, so as to drive the second frame 12 to rotate relatively. Among them, the movement track of the limiting post 211a in the first chute 212a, the movement track of the gear 213, and the movement track of the second frame 12 rotating relative to the first frame 11 can all be regarded as rotations around the same base axis.

[0045] In one embodiment, the connecting mechanism 2 further includes a locking assembly 23. The locking assembly 23 has a locked state and an unlocked state. When the locking assembly 23 is in the locked state, the locking assembly 23 can limit the relative rotation of the first connecting member 211 and the second connecting member 212. The locking assembly 23 includes: a push-pull disk 231, a pivot 232, a first connecting rod 233, and a connecting rod 234. The push-pull disk 231 is used to switch between the locked state and the unlocked state under an external force. One end of the pivot 232 is fixedly connected to the second connecting member 212, and the other end is rotatably connected to the push-pull disk 231. The first connecting member 211 is provided with a second sliding groove 211c for the pivot 232 to pass through. The second sliding groove 211c is arc-shaped, and the pivot 232 can slide along the second sliding groove 211c. The push-pull disk 231 is provided with a third sliding groove 231a for the first connecting rod 233 to slide. One end of the first connecting rod 233 is slidably disposed in the third sliding groove 231a, and the other end is fixedly connected to the second connecting member 212. Both ends of the connecting rod 234 are respectively connected to the pivot 232 and the first connecting rod 233. The first connecting rod 233 has a locked position and an unlocked position in the third sliding groove 231a. When the first connecting rod 233 is located at the locked position, the locking assembly 23 is in the locked state. The push-pull disk 231 can rotate around the pivot 232 under an external force to drive the first connecting rod 233 to slide to the locked position or the unlocked position in the third sliding groove 231a.

[0046] In this embodiment, the push-pull disk 231 rotates around the pivot 232, and the second sliding groove 211c extends in an arc shape along the rotation direction of the push-pull disk 231. The entire circle where the arc is located is set as the third basic circle. Then, the axis of the third basic circle coincides with the axis where the pivot 232 is located. That is, when the first connecting rod 233 slides in the third sliding groove 231a, its sliding trajectory can actually be regarded as rotating around the pivot 232. Therefore, when the first connecting rod 233 slides from one end of the third sliding groove 231a to the other end, under the action of the connecting rod 234, it will drive the second connecting member 212 connected to the first connecting rod 233 to rotate around the pivot 232. The axis of the third basic circle is different from the axis of the first basic circle. Therefore, when the second connecting member 212 rotates around the pivot 232, that is, the axis of the third basic circle, the basic circle where the first sliding groove 212a on the second connecting member 212 is located will deviate from the original position, while the limiting post 211a on the first connecting member 211 remains in the original first basic circle. This makes the extending direction of the first sliding groove 212a and the rotation direction of the limiting post 211a not on the same basic circle, that is, the rotation trajectory of the limiting post 211a is not coaxial with the basic circle where the first sliding groove 212a is located. At this time, when the gear 213 rotates, it can no longer drive the limiting post 211a to rotate in the first sliding groove 212a, thereby realizing the interlocking of the first connecting member 211 and the second connecting member 212.

[0047] In this embodiment, the locking assembly 23 is used to lock the relative position of the first connecting member 211 and the second connecting member 212. When the second connecting member 212 has been adjusted to a preset position, that is, the second frame 12 has been adjusted to a preset angle relative to the first frame 11, the push-pull disk 231 is toggled, and the push-pull disk 231 rotates around the pivot 232 so that the locking assembly 23 is converted from an unlocked state to a locked state. At this time, the first connecting member 211 and the second connecting member 212 cannot rotate relative to each other, and the relative position of the first frame 11 and the second frame 12 is therefore fixed.

[0048] In one embodiment, the flexible LED display screen 100 further includes a handle, which can be rotatably mounted on the side of the support assembly 3 away from the LED display screen 4. The handle includes a lifting ring and a mounting member, one end of the mounting member is mounted on the support assembly 3 by a fastener, and the other end is provided with a fixed shaft, and the lifting ring is rotatably connected to the fixed shaft, so that the lifting ring can be rotated to a suitable position when in use for the convenience of the user to carry, and can be rotated and stored in a preset position when not in use to avoid affecting the installation of other components.
