The word "comprising" or "comprises", and the like, is intended to mean that elements or items that are present in front of "comprising" or "comprising" are included in the word "comprising" or "comprising", and equivalents thereof, without excluding other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to denote relative positional relationships, which may also change accordingly when the absolute position of the object to be described changes.
Fig. 1A is a schematic diagram of a tiled display device in the related art, as shown in fig. 1A, the tiled display device includes a case 200 and a plurality of display modules 100 disposed on the case 200, and the plurality of display modules 100 are tiled together. Fig. 1B is a schematic diagram of a display module according to the related art, as shown in fig. 1B, the display module 100 includes: the display substrate 1 and the bracket main body 2 supporting the display substrate 1. In some products, in order to protect the display substrate 1, the edge of the bracket main body 2 is generally disposed beyond the edge of the display substrate 1. However, since the bracket main body 2 is out of design, in the process of splicing a plurality of display modules, there is a problem that the gap between the display modules is too large, thereby causing a problem that the pictures of the spliced display screen have a hidden seam.
Embodiments of the present disclosure provide a display module, fig. 2 is a cross-sectional view of the display module provided in some embodiments of the present disclosure, and fig. 3 is a plan view of the display module provided in some embodiments of the present disclosure, as shown in fig. 2 and 3, the display module includes: a display substrate 1, a bracket body 2, a driving assembly and a plurality of first sliders 3.
The display substrate 1 may be a mini-LED display substrate or a micro LED display substrate.
The bracket main body 2 is disposed on the non-display side of the display substrate 1, and is configured to support the display substrate 1.
The driving assembly and the plurality of first sliders 3 are disposed at a side of the bracket main body 2 remote from the display substrate 1. The first slider 3 is slidably provided on the bracket main body 2, for example, a guide rail is provided on a surface of the bracket main body 2 away from the display substrate 1, and the first slider 3 is slidably provided on the guide rail.
The driving assembly is connected to the first slider 3, and is used for driving the first slider 3 to move along the surface of the bracket main body 2 away from the display substrate 1, so that the first slider 3 is located in the coverage area of the display substrate 1 or beyond the coverage area of the display substrate 1. For example, in one example, the driving assembly may drive the first slider 3 to move away from or close to the geometric central axis of the display substrate 1, and it should be noted that the geometric central axis of the display substrate 1 refers to an axis passing through the geometric center of the display substrate 1 and extending in the thickness direction of the display substrate 1.
It should be noted that, when the first slider 3 is located in the area covered by the display substrate 1, that is, a plane parallel to the display surface of the display substrate 1 is taken as a reference plane, the orthographic projection of the first slider 3 on the reference plane is located in the orthographic projection range of the display substrate 1 on the reference plane. Correspondingly, the fact that the first slider 3 extends beyond the area covered by the display substrate 1 means that the front projection of the first slider 3 on the reference plane exceeds the front projection of the display substrate 1 on the reference plane.
In the embodiment of the disclosure, the driving assembly can drive the first slider 3 to move along the surface of the bracket main body 2 away from the display substrate 12, so that the first slider 3 is located in the coverage area of the display substrate 1 or beyond the area where the display substrate 1 is located, therefore, during the production and transportation of the display module, the driving assembly can be used to drive the first slider 3 to move, so that the first slider 3 exceeds the area where the display substrate 1 is located, and the display substrate 1 is prevented from being knocked during the transportation; after the assembling and splicing of the display modules are completed, the driving assembly can be used for driving the first sliding block 3 to move, so that the first sliding block 3 is positioned in the coverage area of the display substrates 1, gaps between adjacent display substrates 1 are reduced, and then dark seams in display pictures of the spliced display device are reduced.
In the embodiment of the present disclosure, the edge of the bracket main body 2 does not exceed the edge of the display substrate 1 to reduce a dark seam in the display screen of the tiled display device.
As shown in fig. 2, the driving assembly includes: a fixed part 11, a sliding rod 13 and a first slider 3. The fixing portion 11 may be located near the center of the display substrate 1, and the geometric center axis of the display substrate 1 may pass through the fixing portion 11, for example, may pass through the geometric center of the fixing portion 11.
In some embodiments, the securing portion 11 is bonded to the bracket body 2 by an adhesive layer. The adhesive layer may be double sided tape or other adhesive substance, and the present disclosure is not limited. Of course, the fixing portion 11 may be connected to the bracket main body 2 by other structures such as a screw.
The plurality of first sliders 3 are disposed around the fixing portion 11. In one example, the display substrate 1 has a thin rectangular parallelepiped structure, and the number of the first sliders 3 may be four, and one first slider 3 is provided on each side of the display substrate 1. The front projection of the first sliding blocks 3 on the plane where the display substrate 1 is located may be trapezoidal, and when the four first sliding blocks 3 approach the fixing portion 11 until any one of the first sliding blocks 3 is completely abutted against the side surfaces of two adjacent first sliding blocks 3, the four first sliding blocks 3 may enclose a frame structure, and of course, the first sliding blocks 3 may also have other shapes.
The slide bar 13 extends in the thickness direction of the display substrate 1, and one end is connected to the fixing portion 11. For example, the slide rod 13 may be screwed with the fixed portion 11.
The second sliding block 4 is arranged on the sliding rod 13 in a sliding way, and the second sliding block 4 is connected with the first sliding block 3 through a connecting piece 10; the second slider 4 is configured to lift along the sliding rod 13 to drive the first slider 3 to move near or far from the fixed portion 11. The second slider 4 is lifted up along the slide bar 13, that is, is close to the fixed portion 11 along the Y direction in fig. 2; the second slider 4 descends along the slide bar 13, i.e., moves away from the fixed portion 11 in a direction opposite to the Y direction.
In this embodiment, the second slider 4 may be sleeved on the sliding rod 13, so as to improve the stability of lifting and lowering the second slider 4.
Further, as shown in fig. 2 and 3, the driving assembly further includes: the first end of the guide rod 6 is connected with one of the first sliding block 3 and the fixed part 11, the other one of the first sliding block 3 and the fixed part 11 is provided with a guide hole 5, and the second end of the guide rod 6 extends into the guide hole 5. When the first slider 3 moves closer to or farther from the fixed portion 11, the portion of the guide rod 6 extending into the guide hole 5 correspondingly expands or shortens. The guide rod 6 plays a guiding role in the moving process of the first slider 3, so that the moving process of the first slider 3 is smoother. For example, as shown in fig. 2, the first end of the guide rod 6 is fixedly connected to the fixing portion 11, the first slider 3 is provided with the guide hole 5, and the second end of the guide rod 6 extends into the guide hole 5, however, in other embodiments, the guide hole 5 may be provided on the fixing portion 11 to fixedly connect the guide rod 6 to the first slider 3.
In one example, as shown in fig. 3, a plurality of guide bars 6 may be provided between the first slider 3 and the fixing portion 11, thereby further improving the stability of the movement of the first slider 3.
In some embodiments, the connecting member 10 may be a rigid connecting member 10, and in this case, the first slider 3 may move closer to or further away from the fixing portion 11 as the second slider 4 is lifted. For example, the first slider 3 on the left side in fig. 2 moves close to the fixing portion 11, that is, moves in the X direction in fig. 2; the movement away from the fixed portion 11 is a movement in a direction opposite to the X direction. In other embodiments, the connector 10 may be a flexible connector, such as a rope. In this case, the driving assembly may further include: and one end of the elastic piece 7 is fixedly connected with the first sliding block 3, and the other end of the elastic piece is connected with the fixing part 11.
In the present embodiment, during the production and transportation of the display module, the second slider 4 is controlled to rise, and the first slider 3 is pressed in a direction away from the fixing portion 11 under the elastic force of the elastic member 7, so that the first slider 3 moves away from the fixing portion 11; the first slider 3 on the left side in fig. 2 moves away from the fixing portion 11, that is, moves in a direction opposite to the X direction in fig. 2; the first slider 3 on the right in fig. 2 moves away from the fixed portion 11, that is, moves in the X direction in fig. 2. When the display modules are assembled in a spliced mode, the second sliding block 4 is controlled to move in the direction opposite to the Y direction in fig. 2, so that the first sliding block 3 is pulled to be close to the fixing part 11 through the flexible connecting piece 10.
In some embodiments, the elastic member 7 may be a compression spring that is sleeved on the guide rod 6, so as to prevent the elastic member 7 from shaking during the expansion and contraction process.
As shown in fig. 2, in some embodiments, the second slider 4 includes: the mounting seat 402 and the magnetic piece 401, wherein the mounting seat 402 is arranged on the sliding rod 13 in a sliding manner and is connected with the first sliding block 3 through the connecting piece 10; wherein one or more connectors 10 may be connected between the mounting base 402 of the second slider 4 and each of the first sliders 3. The magnetic member 401 is disposed on the mount 402. For example, the mounting base 402 may be provided with a mounting groove, in which the magnetic member 401 is disposed, or the mounting base 402 may be a hollow housing, in which the magnetic member 401 is disposed.
Fig. 4 is a schematic view of a state of a display module subjected to magnetic force provided in some embodiments of the present disclosure, because the second slider 4 includes a magnetic member 401, when the second slider 4 is controlled to lift, a magnetic device may be placed on the display side of the display substrate 1, as shown in fig. 4, for example, the magnetic device includes a suction cup 14 and a magnetic member 141 located on the suction cup 14, and the magnetic device may at least apply a repulsive force to the second slider 4, so as to control the second slider 4 to lift, and further drive the first slider 3 to move close to the fixing portion 11. When the first slider 3 is required to move away from the fixed portion 11, the magnetic means is removed and the first slider 3 moves away from the fixed portion 11 under the elastic action of the elastic member 7.
As shown in fig. 2, the end of the slide bar 13 remote from the fixed portion 11 is provided with a stopper portion 12, thereby preventing the second slider 4 from being separated from the slide bar 13 during sliding. Wherein, the limiting part 12 can be in threaded connection with the sliding rod 13 or formed as a whole.
As shown in fig. 2, the fixing portion 11 may be provided with a receiving groove 9, and after the second slider 4 is lifted, at least a portion of the second slider may enter the receiving groove 9 through the opening of the receiving groove 9, where the opening of the receiving groove 9 faces away from the display substrate 1. In addition, the fixing portion 11 may further be provided with a connecting groove 8, one end of the connecting groove 8 communicates with the accommodating groove 9, and the other end extends to a surface of the fixing portion 11 close to the first slider 3.
As shown in fig. 4, in some embodiments, during the transportation of the display module, a magnetic device (for example, a sucker 14 with a built-in magnet) is used to apply a magnetic attraction force to the magnetic member 401 in the second slider 4, so as to drive the first slider 3 to move close to the display substrate 1. The magnetic device is removed at this time, and under the elastic action of the elastic member 7, the first slider 3 moves away from the fixing portion and exceeds the range covered by the display substrate 1, so as to prevent the display substrate 1 from being bumped during transportation, and at this time, a part of the flexible connecting member (e.g., a rope) is located in the connecting groove 8 and maintains a horizontal stable state. Alternatively, during transportation of the display substrate, no magnetic force may be applied to the second slider 4, and at this time, the first slider 3 may be driven to move away from the fixed portion by the elastic action of the elastic member 7.
The material of the flexible connecting piece is not limited, and for example, the flexible connecting piece can be a nylon rope, a steel wire or the like. In some embodiments, the cross section of the flexible connection unit may be circular or approximately circular, and the diameter of the cross section of the flexible connection unit may be between 0.2mm and 0.8mm, for example, 0.5mm, so as to ensure that the flexible connection unit has high strength and prevent breakage during pulling of the first slider 3.
Fig. 5 is a schematic diagram of a display module splicing and assembling process provided in some embodiments of the present disclosure, for the display module on the right side in fig. 5, a magnetic device is used to apply a repulsive magnetic force to the magnetic piece 401 in the second slider 4, and the second slider 4 is forced to slide along the sliding rod 13 away from the display substrate 1, so as to drive the first slider 3 to approach the fixing portion. As shown in fig. 5, after the display module is spliced with other display modules (i.e., the display modules on the left side in fig. 5), the magnetic device is removed, and under the elastic action of the flexible connecting piece, the first slider 3 moves away from the fixing portion until contacting with the first sliders 3 of the other display modules.
Fig. 6 is a schematic structural diagram of a display substrate provided in some embodiments of the present disclosure, and as shown in fig. 6, the display substrate 1 includes: the light emitting element 101, the protective film 102, and the substrate 104, the light emitting element 101, the protective film 102, and the driving circuit layer 103 are all disposed on the substrate 104, the protective film 102 is located at least in a region between adjacent light emitting elements 101, and in some embodiments, the protective film 102 may also cover a surface of the light emitting element 101 away from the substrate 104. The display substrate 1 may further include a driving circuit layer 103 disposed on the substrate 104 for providing driving signals to the light emitting elements 101. The protective film 102 may be a film layer including carbon black particles, in which case the protective film 102 no longer covers the surface of the light emitting member 101 away from the substrate 104 to prevent light emission of the light emitting member 101 from being affected. The edge of the protective film 102 may be beyond the edge of the substrate 104 or may be flush with the edge of the substrate 104. By providing the protective film 102, the contrast of the display screen of the display substrate 1 can be improved. Since the driving assembly can drive the first slider 3 to move along the surface of the bracket body 2 away from the display substrate 1 during the production and transportation processes, the side edges of the protective film 102 are prevented from being scratched.
Fig. 7 is a schematic diagram of a tiled display device provided in some embodiments of the present disclosure, and as shown in fig. 7, the tiled display device includes a plurality of display modules 100 in the above embodiments, where the plurality of display modules 100 are tiled together.
In some embodiments, the tiled display device further includes: the case 200, the plurality of display modules 100 are fixed on the case 200.
