[0028] The present application will be described in detail below with reference to the accompanying drawings and optional embodiments. It should be noted that the embodiments described below or the technical features thereof can be combined with each other to form new embodiments without conflict.

[0029] Figure 1 FIG. 1 is a schematic view of a first embodiment of a curved splicing screen of the present application, Figure 2 FIG. 2 is a top view of the first embodiment of the curved splicing screen of the present application, as Figure 1 and Figure 2 As shown in the drawings, the present application discloses a curved splicing screen 10, comprising a back plate 100, a glue frame 200, and at least two display panels 300. The display panels 300 are arranged above the back plate 100. The glue frame 200 is arranged between the display panels 300 and the back plate 100. The glue frame 200 is connected to the back plate 100. The display panels 300 are connected to the glue frame 200. The glue frame 200 comprises a first frame body 210 and a second frame body 220 arranged oppositely. A splicing piece 400 is arranged between the first frame body 210 and the second frame body 220. One end of the splicing piece 400 is connected to the first frame body 210, and the other end of the splicing piece 400 is connected to the second frame body 220. The splicing piece 400 divides the glue frame 200 into two mounting areas 600. The at least two display panels 300 are respectively arranged in the two mounting areas 600. The at least two display panels 300 are respectively connected to the splicing piece 400.

[0030] The application sets the splicing piece 400 between the first frame body 210 and the second frame body 220 arranged oppositely on the glue frame 200, connects the two ends of the splicing piece 400 with the first frame body 210 and the second frame body 220 respectively to form a frame structure similar to a "day" character, so that the splicing piece 400 and the glue frame 200 have good stability and form a whole; in the case that the splicing frame formed by the splicing piece 400 and the glue frame 200 is combined to pre-divide the area for splicing, the two display panels 300 are respectively installed into the two mounting areas 600, and the two display panels 300 are directly connected with the frame composed of the glue frame 200 and the splicing piece 400, the two display panels 300 are limited and fixed by the integrity and stability of the frame, so that the two display panels 300 do not need to be directly spliced with each other, and a complete spliced screen can be formed, so that the curved spliced screen 10 is not easy to shake or separate during use or carrying, and the stability of the curved spliced screen 10 is effectively improved.

[0031] In order to enable the splicing piece 400 to effectively and stably support and splice the display panel 300 mounted in the mounting area 600, the structure of the splicing piece 400 is specifically designed, and the specific design is as follows:

[0032] The splicing piece 400 includes a support part 410 and a limiting part 420, one end of the support part 410 is connected with the first frame body 210, the other end is connected with the second frame body 220, and the limiting part 420 is arranged at the middle of the side of the support part 410 facing the display panel 300; the two ends of the limiting part 420 extend along the length direction of the support part 410, and the limiting part 420 is perpendicular to the support part 410; the two sides of the support part 410 in the horizontal direction of the limiting part 420 respectively bear and are connected with the display panel 300, and the two sides of the limiting part 420 in the horizontal direction respectively abut against the display panel 300.

[0033] In the embodiment, by forming the support portion 410 and the limiting portion 420 into a structure similar to an inverted T shape, the limiting portion 420 is arranged at the middle of the support portion 410, and the support portion 410 is divided into left and right sides with the limiting portion 420 as the center. When the two display panels 300 are spliced, only the two display panels 300 need to be respectively installed into the two installation areas 600, and one side of the two display panels 300 is respectively connected to the left and right sides of the support portion 410. The left and right sides of the support portion 410 respectively support one side of the two display panels 300 in the longitudinal direction, and the other side of the two display panels 300 is connected to the rubber frame 200 to form a stable fixed connection. Glass glue can be applied between the support portion 410 and the display panel 300 and between the display panel 300 and the rubber frame 200, so that the two display panels 300 can be combined with the splicing frame formed by the support portion 410 and the rubber frame 200 to form better adhesion and fixation, effectively preventing the display panel 300 from falling off and also having a certain buffering capacity. The limiting portion 420 simultaneously abuts against the two display panels 300 from both sides to limit the two display panels 300 and support the display panel 300 from the side, so that the two display panels 300 are not easy to shake after installation, further improving the connection stability of the curved splicing screen 10.

[0034] In the embodiment, the two ends of the limiting portion 420 and the support portion 410 are fixedly connected to the middle of the first frame 210 and the second frame 220. That is, the limiting portion 420 and the support portion 410 in the splicing piece 400 are simultaneously connected to the rubber frame 200 and can be integrally formed with the rubber frame 200, so that the splicing frame formed by the splicing piece 400 and the rubber frame 200 has better integrity, and the connection strength between the splicing piece 400 and the rubber frame 200 is increased, so that the splicing piece 400 is not easy to break or fall off at a certain place of the frame, and can stably splice multiple display panels 300. Of course, the splicing piece 400 and the rubber frame 200 in the embodiment can also be detachably connected, and the application does not specifically limit the connection mode between the splicing piece 400 and the rubber frame 200, but only takes the integral forming between the splicing piece 400 and the rubber frame 200 as an example.

[0035] It is worth mentioning that, since the application is for the splicing and assembly of the curved display panel 300, in order to better connect the splicing piece 400 and the curved display panel 300, the structure size and shape of the splicing piece 400 are also designed, and the specific design is as follows:

[0036] The height of the limiting portion 420 is less than or equal to the thickness of the display panel 300 and greater than half of the thickness of the display panel 300; the supporting portion 410 is arc-shaped, and the curvatures of the supporting portion 410 and the display panel 300 at the connection position are the same.

[0037] In this way, when the two curved display panels 300 are installed on the splicing frame composed of the splicing piece 400 and the rubber frame 200, the limiting portion 420 in the splicing piece 400 does not protrude from the surface of the curved display panel 300, which further improves the aesthetic appearance of the curved splicing screen 10; the curvatures of the supporting portion 410 and the display panel 300 at the connection position are the same, so that the supporting portion 410 can better fit the shape of the display panel 300, further increasing the connection area between the supporting portion 410 and the display panel 300, making the connection between the display panel 300 and the supporting portion 410 more stable, and the display panel 300 is not easy to fall off from the supporting portion 410; at the same time, it also makes the stress between the display panel 300 and the supporting portion 410 more uniform, effectively avoiding the problem of rupture of the display panel 300 when extruded by the supporting portion 410 under external force.

[0038] It should be noted that the number of display panels 300 actually installed in the installation area 600 divided by the splicing piece 400 and the rubber frame 200 after connection can be determined according to the specific size of the display panel 300, for example, when a display panel 300 with a larger size needs to be spliced, one display panel 300 can be installed in each of the two installation areas 600 divided by the splicing piece 400, and the splicing piece 400 can be used to carry two display panels 300 at the same time to form a splicing screen spliced by two display panels 300, when a display panel 300 with a smaller size needs to be spliced, multiple display panels 300 can be installed in each of the two installation areas 600, and the splicing piece 400 can be used to carry multiple display panels 300 at the same time; for example, when four display panels 300 need to be spliced, two display panels 300 are installed in each of the two installation areas 600, respectively, to form a splicing screen spliced by four display panels 300; the number of display panels 300 actually installed in the installation area 600 is not limited in the present application, and only one display panel 300 installed in each installation area 600 is taken as an example.

[0039] Figure 3 The top view of the second embodiment of the curved splicing screen of the present application is shown in FIG. 6. Figure 3 Figure 3 The embodiment shown in FIG. 6 is based on Figure 1 ​The two ends of the limiting part 420 are respectively provided with protrusions 421, and the first frame body 210 and the second frame body 220 are respectively provided with limiting grooves 230 corresponding to the positions of the protrusions 421, and the protrusions 421 are embedded in the limiting grooves 230 to be fixed with the limiting grooves 230.

[0040] In actual use, the splicing piece 400 may bear multiple display panels 300 at the same time, so that the splicing piece 400 bears a large pressure, and the position of the splicing piece 400 is most likely to be damaged with the increase of use time.

[0041] Therefore, in the embodiment, the protrusions 421 are arranged at the two ends of the limiting part 420, the limiting grooves 230 are arranged at the positions corresponding to the protrusions 421 of the first frame body 210 and the second frame body 220 of the rubber frame 200, and when the splicing piece 400 is installed on the rubber frame 200, the protrusions 421 on the limiting part 420 are embedded in the limiting grooves 230 of the first frame body 210 and the second frame body 220, and the installation of the splicing piece 400 is completed, which is simple and convenient, and the entire rubber frame 200 does not need to be replaced, and only the splicing piece 400 needs to be replaced, so that the cost is effectively saved.

[0042] Figure 4 FIG. 3 is a schematic view of a third embodiment of the curved splicing screen of the present application, as shown in Figure 4 Figure 4 The embodiment shown in Figure 1 is improved based on the embodiment shown in The supporting part 410 of the splicing piece 400 is not arc-shaped and is made of elastic material.

[0043] The embodiment shown in Figure 1 is different from the embodiment shown in

[0044] When the display panel 300 and the support portion 410 of the splicing piece 400 are connected by the glass glue, since the display panel 300 is arc-shaped at the connection with the support portion 410, the portion connecting the support portion 410 and the display panel 300 will have a tendency to curl upward. In order to make the support portion 410 deform more easily and prevent the support portion 410 and the display panel 300 from being pulled apart, causing the display panel 300 to fall off the support portion 410, a plurality of first grooves 411 are arranged on the side of the support portion 410 away from the display panel 300. The plurality of first grooves 411 thin the local thickness of the support portion 410, and the plurality of first grooves 411 are arranged along the support portion 410 in the direction of the bending of the display panel 300, so that the support portion 410 deforms more easily in the direction in which the display panel 300 bends. In this way, the support portion 410 deforms in the bending direction of the display panel 300 to release the pulling force between the display panel 300 and the support portion 410, so that the display panel 300 can be stably connected to the support portion 410, further improving the stability of the splicing piece 400 in splicing the display panel 300.

[0045] Figure 5 FIG. 4 is a schematic view of a fourth embodiment of the curved splicing screen of the present application, as shown in Figure 5 Figure 5 The embodiment shown is improved based on Figure 1 The curved splicing screen 10 further includes a lamp panel 500, which is arranged in the back plate 100 and below the plurality of display panels 300. The lamp panel 500 is provided with a receiving groove 510 at a position corresponding to the splicing piece 400, and the receiving groove 510 is provided with a light-emitting unit 520. The light-emitting unit 520 does not protrude from the receiving groove 510. The splicing piece 400 is made of transparent material.

[0046] In the embodiment, the splicing piece 400 is made of transparent material, and the light-emitting unit 520 is arranged at a position of the lamp panel 500 corresponding to the splicing piece 400, so that the light emitted by the light-emitting unit 520 can directly pass through the splicing piece 400. In this way, the problem of light blocking caused by the splicing piece 400 at the joint between the two display panels 300 after splicing can be effectively solved, and the display effect of the curved splicing screen 10 can be further improved. The light-emitting unit 520 is embedded in the receiving groove 510 on the lamp panel 500, and the light-emitting unit 520 does not protrude from the receiving groove 510, i.e., the height of the light-emitting unit 520 is smoothly transitioned with the lamp panel 500, which can effectively prevent the light-emitting unit 520 from partially protruding to cause abnormal optical taste. The receiving groove 510 shields the light emitted by the light-emitting unit 520 and diffuses it to the adjacent light-emitting units 520, which can effectively improve the light mixing problem.

[0047] ​Since only one complete lamp plate 500 is used in the curved spliced screen 10 formed by splicing in the present application to provide a normal display light source for the spliced display panel 300, in order to make the lamp plate 500 in the curved spliced screen 10 more easily bent to the curvature cooperating with the curved display panel 300 in the process of manufacturing, and not easily occur the phenomenon of warping, the structure of the lamp plate 500 in the curved spliced screen 10 is improved in the present application, and the specific improvements are as follows:

[0048] Figure 6 The schematic diagram of the fifth embodiment of the curved spliced screen of the present application is shown in FIG. 12, Figure 6 Figure 6 The embodiment shown is based on the improvement that Figure 5 The lamp plate 500 is provided with a plurality of second grooves 530 on the side away from the display panel 300, and the plurality of second grooves 530 are arranged at intervals along the length direction of the lamp plate 500.

[0049] Since the side of the lamp plate 500 away from the display panel 300 is bent in the direction away from the display panel 300 in the process of bending the flat lamp plate 500 into the curved lamp plate 500, and the lamp plate 500 itself has a certain thickness, therefore, in the process of bending the lamp plate 500, the side of the lamp plate 500 away from the display panel 300 will be deformed by bending and will be subjected to a pulling force, which is not easy to deform and is easy to warp. In order to more easily release such pulling force and make the lamp plate 500 more easily deformed, the embodiment is provided with a plurality of second grooves 530 on the side of the lamp plate 500 away from the display panel 300, which makes the local thickness of the lamp plate 500 thinner and more easily deformed in the process of bending, and the plurality of second grooves 530 are arranged at intervals along the length direction of the lamp plate 500. When the lamp plate 500 is bent, the similar “outward bending” force on the lamp plate 500 can be effectively released by the plurality of second grooves 530 arranged at intervals, so that the lamp plate 500 can be bent to a large curvature without being easily broken, which is more conducive to the design of the curved spliced screen 10 with a large curvature without affecting the normal display of the curved spliced screen 10.

[0050] Further, in order to prevent the lamp plate 500 from being dislocated with other optical films in the process of bending the flat lamp plate 500 into the curved lamp plate 500, which affects the display effect of the curved spliced screen 10, the fixing method between the lamp plate 500 and the back plate 100 is improved in the present application, and the specific improvements are as follows:

[0051] Figure 7 The schematic diagram of the sixth embodiment of the curved spliced screen of the present application is shown in FIG. 13, Figure 7 Figure 7 The embodiment shown is based on the improvement that​​Figure 6 In the improved embodiment of the back plate 100, the bottom plate 110 is arranged on the side of the lamp plate 500 away from the display panel 300, the bottom plate 110 abuts against the lamp plate 500, the bottom plate 110 is provided with a fixing portion 111 at the position corresponding to the second groove 530, and the fixing portion 111 is embedded in the second groove 530; the side of the fixing portion 111 close to the second groove 530 is arc-shaped, and the second groove 530 is matched with the shape of the fixing portion 111.

[0052] Different from the embodiment shown in Figure 5 In the embodiment, the fixing portion 111 is arranged on the bottom plate 100 at the position corresponding to the second groove 530 of the lamp plate 500, the fixing portion 111 can be a protrusion 421 extending from the side of the bottom plate 100 close to the lamp plate 500 towards the lamp plate 500, or a plurality of protrusions 421 arranged on the lamp plate 500 additionally; for example, when the fixing portion 111 is a protrusion 421 arranged on the bottom plate 100 additionally, during the installation of the lamp plate 500 and the bottom plate 100, since the fixing portion 111 on the bottom plate 100 and the second groove 530 on the lamp plate 500 are both easy to observe, it is only necessary to correspond the positions of the plurality of second grooves 530 on the lamp plate 500 with the positions of the plurality of fixing portions 111 on the bottom plate 100 one by one, and then to align and fix the plurality of second grooves 530 and the plurality of fixing portions 111, so that the lamp plate 500 is buckled above the bottom plate 100, realizing the quick positioning and installation between the lamp plate 500 and the bottom plate 100, and further improving the installation rate between the lamp plate 500 and the bottom plate 100.

[0053] In addition, during the bending of the lamp plate 500 and the bottom plate 100, the side of the lamp plate 500 provided with the second groove 530 is bent towards the direction of the bottom plate 100, and the side of the bottom plate 100 provided with the fixing portion 111 is bent towards the direction of the lamp plate 500, so that the second groove 530 on the lamp plate 500 and the fixing portion 111 embedded in the second groove 530 form a mutual “occlusion” shape, the relative position between the lamp plate 500 and the bottom plate 100 is not easy to change, the lamp plate 500 still remains at the initial position installed on the bottom plate 100, and the dislocation between the optical film above the lamp plate 500 is not easy to occur, so that it can be ensured that the light emitted by the lamp plate 500 can be as much as possible to irradiate on the optical film after the bending of the lamp plate 500, reducing the light loss, and further improving the display effect of the curved splicing screen 10.

[0054] Further, in order to make the lamp plate 500 and the bottom plate 100 fixed through the cooperation between the second groove 530 and the fixing portion 111, and further prevent the warping of the lamp plate 500, the embodiment improves the connection mode between the lamp plate 500 and the bottom plate 100, and the specific improvements are as follows:

[0055] Figure 8 FIG. 7 is a schematic view of a seventh embodiment of the curved splicing screen according to the present application, as shown in the figure, Figure 8 Figure 8 The embodiment shown is based on the improvement that the fixing part 111 is made of metal material, and the inner surface of the second groove 530 is covered with an adsorption layer 540 made of magnetic material; the fixing part 111 is magnetically adsorbed with the adsorption layer 540. Figure 7

[0056] The difference between the present embodiment and the previous embodiment is that in the present embodiment, the fixing part 111 of the backboard 100 is made of metal material. When the backboard 100 is a hardware backboard 100, the fixing part 111 on the backboard 100 can be directly a protrusion 421 on the hardware backboard 100. When the backboard 100 is a plastic backboard 100, the fixing part 111 can be a metal protrusion 421 structure additionally arranged on the backboard 100, and a layer of adsorption layer 540 with magnetic material is arranged in the second groove 530 of the lamp panel 500, so that the fixing part 111 made of metal material can be magnetically adsorbed with the adsorption layer 540 in the second groove 530.

[0057] After the installation between the lamp panel 500 and the backboard 100, the second groove 530 on the lamp panel 500 is buckled on the fixing part 111 of the backboard 100 and forms magnetic adsorption. When the lamp panel 500 and the backboard 100 are bent at the same time, the lamp panel 500 always adheres to the backboard 100 due to the influence of magnetic adsorption, which can effectively avoid the warping phenomenon of the lamp panel 500 in the bending process, and further improve the stability of the connection between the lamp panel 500 and the backboard 100. Even without using the way of adhesive to bond the lamp panel 500 and the backboard 100, but using the way of magnetic adsorption can complete the stable connection between the lamp panel 500 and the backboard 100, saving the material cost, and also facilitating disassembly.
