Compared with Display technologies such as LCD (Liquid Crystal Display), OLED (Organic Light-Emitting Diode), and the like, Micro-LED has advantages in brightness, resolution, energy consumption, service life, response speed, thermal stability, and the like, and is an internationally recognized future Display technology.

Currently, large screen display markets are very large, such as mall advertisements, center consoles, conference rooms, stadiums, and so on. The current large-screen display mainly has four design schemes: the first scheme is an LCD splicing screen, which has lower cost, can only be applied indoors and has obvious splicing seams; the second scheme is a Printed Circuit Board (PCB) small-pitch LED tiled screen, which can realize seamless tiling and highlight display, but has a low PPI and a large and complex module; the third scheme is projection display, the scheme has low brightness, unclear picture and easy deformation of images, and can only meet the requirements of general indoor office; the fourth scheme is a glass-based Mini-LED spliced screen, which can realize seamless splicing, high brightness and high PPI display, is light, thin and attractive, and has the defects of obvious granular sensation and inconvenience for short-distance viewing.

The current Micro-LED large-screen display technology has serious seam splicing problems due to processing errors of a splicing mechanism and no seam adjusting mechanism, and even causes mutual collision and damage between Micro-LED display units during splicing.

At present, in the Micro-LED large-screen display technology, due to the processing error of a splicing mechanism and the absence of a splicing adjusting mechanism, the problem of serious splicing exists, and even the Micro-LED display units are mutually collided and damaged during splicing. In general, the following methods are common methods for improving the seam of the Micro-LED tiled display device: the first method is to improve the precision of the splicing mechanism, the method has high cost, and the precision is difficult to ensure when the splicing mechanism is bigger, so that the infinite splicing of a large screen cannot be realized; the second method is that the splicing mechanism is adjusted by screws, and in the method, the splicing mechanism is large and complex, and the larger the size is, the more difficult the precision is to ensure; the third method is that the splicing mechanism adopts a fixed magnetic attraction mode, in the method, the display unit is not easy to be accurately placed on the magnetic splicing mechanism, and the splicing seam is difficult to adjust after the magnetic attraction.

Fig. 1 is a schematic cross-sectional structure diagram of an exemplary tiled display device 1 ', and fig. 2 is a top view of a tiling mechanism 2 ' in the tiled display device 1 ' provided in fig. 1. The exemplary tiled display device 1 'comprises a tiled mechanism 2', a plurality of Micro-LED display units 3 'tiled on one side of the tiled mechanism 2', and a plurality of fixed magnetic attraction mechanisms 4 'arranged in one-to-one correspondence with the plurality of Micro-LED display units 3'; the fixed magnetic attraction mechanism 4 ' comprises a magnet piece 5 ' arranged at the back (close to one side of the splicing mechanism 2 ') of the corresponding Micro-LED display unit 3 ' and a fixed magnet 6 ' embedded on the splicing mechanism 2 ' and connected with the magnet piece 5 ' in a corresponding magnetic attraction manner. The magnet piece 5 'is fixedly connected with the Micro-LED display unit 3', and the fixed magnet 6 'is fixedly connected with the splicing mechanism 2'.

When the splicing display device 1 'shown in fig. 1 is manufactured, when the Micro-LED display unit 3' is placed on the splicing mechanism 2 ', the Micro-LED display unit 3' is rapidly fixed on the splicing mechanism 2 'under the action of the magnetic attraction force of the magnet piece 5' and the fixed magnet 6 ', so that the position of the Micro-LED display unit 3' is prone to be adjusted and deviated, and therefore splicing seams are generated; in addition, the magnet piece 5 'is fixedly connected with the Micro-LED display unit 3' and the fixed magnet 6 'is fixedly connected with the splicing mechanism 2', so that an acting force larger than a magnetic attraction force needs to be applied to the Micro-LED display unit 3 'to adjust the position of the Micro-LED display unit 3' if the splicing seam needs to be adjusted, the Micro-LED display unit 3 'is easily damaged in the process, or the Micro-LED display units 3' are damaged due to mutual collision.

In order to solve the technical problems, the application provides a splicing display device and a manufacturing method thereof, wherein a magnetic attraction device movably connected with the splicing mechanism is arranged on the splicing mechanism, and a Micro-LED display unit and the splicing mechanism are fixed in a magnetic attraction mode, so that an infinite screen splicing technology can be realized, and the splicing seam can be flexibly adjusted to ensure seamless splicing.

Specifically, the splicing mechanism 2 has a first surface 7 and a second surface 8 which are oppositely arranged, wherein the first surface 7 is used for splicing a plurality of display units 3. It will be appreciated that the spacing through-hole 6 extends through both the first surface 7 and the second surface 8.

Specifically, the shape of the projection of the limiting through hole 6 in the direction perpendicular to the splicing mechanism 2 includes any one of a rectangle and a circle, but is not limited thereto.

Specifically, as shown in fig. 4, a plurality of display units 3 are arranged on the first surface 7 of the splicing mechanism 2 in a splicing manner and are arranged in one-to-one correspondence with the plurality of splicing areas 5. It will be appreciated that each display element 3 is located at a corresponding tiled area 5.

It should be noted that the shape and size of the projection of each display unit 3 in the direction perpendicular to the splicing mechanism 2 may be the same as the shape and size of the corresponding splicing region 5; of course, in some embodiments, the display units 3 located at the edge of the splicing mechanism 2 may be slightly beyond the edge of the splicing area 5, i.e. beyond the edge of the splicing mechanism 2, in a direction away from the splicing mechanism 2.

Specifically, the display unit 3 is a display screen, such as a Micro-LED display screen, but is not limited thereto. In one embodiment, each display unit 3 can display independently, but is not limited thereto.

Wherein, the connecting mechanism 4 comprises a first connecting piece 9 and a second connecting piece 10; the first connecting pieces 9 are fixedly connected to one sides of the corresponding display units 3 close to the splicing mechanisms 2 and are positioned in the corresponding limiting through holes 6; the second connecting piece 10 is located on one side of the first connecting piece 9 far away from the display unit 3, is detachably connected with the first connecting piece 9 in an adsorption manner, and is movably connected with the splicing mechanism 2.

The movable connection of the second connecting member 10 and the splicing mechanism 2 means that the second connecting member 10 is in contact with a surface (for example, a second surface) of the splicing mechanism 2, but is not fixedly connected.

Specifically, the second connecting member 10 is movably connected to a side of the splicing mechanism 2 away from the display unit 3.

In one embodiment, the first connecting member 9 is an iron piece and the second connecting member 10 is a magnet piece. In another embodiment, the first and

second connectors

9, 10 are magnet blocks. It is understood that the first and

second connectors

9 and 10 are connected by magnetic attraction.

In a specific embodiment, the radial width (width in a direction parallel to the first surface 7) of the first connecting member 9 is smaller than the aperture of the corresponding limiting through hole 6, so that the first connecting member 9 can move radially in the limiting through hole 6, and the position of the display unit 3 can be adjusted as required.

Specifically, the thickness of the first connecting piece 9 is equal to the depth of the limiting through hole 6; one side of the second connecting piece 10 close to the first connecting piece 9 is attached to one side of the first connecting piece 9 and one side of the splicing mechanism 2 far away from the display unit 3. It can be understood that the second connecting member 10 in the embodiment of the present application is located on a side of the splicing mechanism 2 away from the display unit 3, i.e. protruding from the second surface 8 of the splicing mechanism 2, so that the second connecting member 10 is more convenient to grasp during installation and disassembly.

It should be noted that the thickness and depth described in the embodiment of the present application refer to the length in the direction perpendicular to the splicing mechanism 2.

Specifically, the radial cross-sectional shape of the first connecting member 9 and the second connecting member 10 may be circular or rectangular, but may also be other shapes, and is not limited herein.

In the process of manufacturing the tiled display device 1, a way of first tiling and then fixing by adsorption (such as magnetic attraction) is adopted. In a specific embodiment, the m (m is an integer greater than or equal to 1) th display unit 3 is placed in a corresponding splicing area 5 on the splicing mechanism 2, so that a first connecting piece 9 at the back of the display unit 3 (opposite to the light-emitting surface) is located in a corresponding limiting through hole 6, after the position of the display unit 3 is adjusted, a corresponding second connecting piece 10 is correspondingly connected with the first connecting piece 9 in an absorbing manner from the side, far away from the display unit 3, of the splicing mechanism 2, and therefore the m-th display unit 3 is fixed on the splicing mechanism 2; then the (m + 1) th display unit 3 is placed in the corresponding splicing area 5 of the splicing mechanism 2, the first connecting piece 9 at the back of the display unit 3 is positioned in the corresponding limiting through hole 6, the position of the display unit 3 is adjusted to be adjacent to the (m) th display unit 3, finally, the corresponding second connecting piece 10 is correspondingly adsorbed and connected with the first connecting piece 9 from one side of the splicing mechanism 2 far away from the display unit 3, and the (m + 1) th display unit 3 is fixed on the splicing mechanism 2. By adopting the method, the plurality of display units 3 can be sequentially spliced and fixed on the splicing mechanism 2 to form the large-size spliced display device 1 (large-screen display device). If discover that some piece needs the adjustment after the concatenation is accomplished, can directly move away from corresponding second connecting piece 10, then adjust the position of the display element 3 that corresponds, wait that the piece is adjusted and accomplish the back, place second connecting piece 10 to the one side that the display element 3 was kept away from to corresponding spacing through-hole 6 again, make it adsorb with first connecting piece 9 and be connected.

It can be understood that when adjusting the seam splicing of the tiled display device 1 in the embodiment of the present application, the corresponding second connecting member 10 needs to be moved away first, and then the position of the display unit 3 is adjusted without resistance, so as to adjust the seam splicing; the process can avoid the problem that the display unit 3 is damaged due to the fact that the abutted seam is adjusted by strength or the adjacent display units 3 collide with each other to cause damage.

In the embodiment of the application, the splicing mechanism 2 is simple in structural design and low in cost, not only can realize an infinite screen splicing technology, but also can realize flexible adjustment of splicing seams, and ensures seamless splicing; in addition, the splicing mechanism 2 is movably connected with the second connecting piece 10 (such as a magnet block) and the display units 3 are spliced in a mode of splicing first and then adsorbing and fixing, so that the problem that the display units 3 are damaged or adjacent display units 3 collide with each other to cause damage due to the fact that splicing seams are adjusted strongly can be solved; therefore, the splicing seam of the splicing display device 1 can be improved, seamless splicing display is achieved, the infinite screen splicing technology is achieved, the display quality of the large-size splicing display device 1 is improved, and the competitiveness and the market share of products are improved.

Example two

Specifically, the first connecting portion 11 and the second connecting portion 12 may be integrally formed, that is, the same material.

It can be understood that in the embodiment of the present application, the thickness of the first connecting member 9 is smaller than the depth of the limiting through hole 6, and the total thickness of the first connecting portions 11 of the first connecting member 9 and the second connecting member 10 is equal to the depth of the limiting through hole 6; the second connecting portion 12 of the second connecting member 10 protrudes from the second surface 8 of the splicing mechanism 2, so that the second connecting member 10 can be more conveniently grabbed during installation and disassembly.

Specifically, the radial cross-sectional shapes of the first connection portion 11 and the second connection portion 12 may be circular or rectangular, and may also be other shapes, which is not limited herein.

Specifically, in the process of splicing the display units 3, after the positions of the display units 3 on the first surface 7 of the splicing mechanism 2 are adjusted, the first connecting portions 11 of the second connecting members 10 can be directly inserted into the corresponding limiting through holes 6 from the side, far away from the display units 3, of the splicing mechanism 2, so that the first connecting members are connected with the corresponding first connecting members 9 in an adsorption manner. When the splicing seam of the splicing display device 1 is adjusted, the first connecting parts 11 of the second connecting pieces 10 are firstly drawn out from the corresponding limiting through holes 6, then the positions of the corresponding display units 3 are adjusted, and finally the first connecting parts 11 of the second connecting pieces 10 are reinserted into the corresponding limiting through holes 6 to be connected with the corresponding first connecting pieces 9 in an adsorption mode.

In one embodiment, as shown in fig. 7, the second connecting member 10 is completely located in the second sub-limiting through hole 14, which is beneficial to reduce the overall thickness of the tiled display device 1. It will be appreciated that the thickness of the second connecting member 10 is less than or equal to the depth of the second sub-limiting through-hole 14. Since the second connecting member 10 does not protrude from the second surface 8 of the splicing mechanism 2, the second connecting member 10 can be mounted or dismounted by means of a tool (e.g., a magnet block). Of course, a groove or a notch for gripping may be provided at a position of the second connecting member 10 close to the second surface 8 of the splicing structure, and the specific structure will not be described in detail here.

Specifically, in the process of splicing the display units 3, after the positions of the display units 3 on the first surface 7 of the splicing mechanism 2 are adjusted, the second connecting members 10 can be directly inserted into the corresponding second sub-limiting through holes 14 from the side, far away from the display units 3, of the splicing mechanism 2, so that the second connecting members are connected with the corresponding first connecting members 9 in an adsorption manner. When the splicing seam of the splicing display device 1 is adjusted, the second connecting piece 10 is firstly drawn out from the corresponding second sub-limiting through hole 14, then the position of the corresponding display unit 3 is adjusted, and finally the second connecting piece 10 is reinserted into the corresponding second sub-limiting through hole 14 to be connected with the corresponding first connecting piece 9 in an adsorption mode.

Of course, in other embodiments, the second connecting member 10 may also protrude from the second surface 8 of the splicing mechanism 2, so that the second connecting member 10 is more convenient to grasp when being installed and disassembled.

Example four

As shown in fig. 3 and 8, the present embodiment further provides a tiled display device, which is different from the third embodiment in that the second connecting member 10 includes a first connecting portion 11 and a second connecting portion 12 fixedly connected to each other; the radial width of the second connecting portion 12 is greater than the radial width of the first connecting portion 11; the first connecting portion 11 is located in the second sub-limiting through hole 14 and detachably connected with one side, far away from the display unit 3, of the first connecting piece 9 in an adsorption manner, and the second connecting portion 12 is located on one side, far away from the display unit 3, of the splicing mechanism 2 and movably connected with the splicing mechanism 2.

Specifically, the specific structures of the splicing mechanism and the connecting mechanism refer to the foregoing embodiments, and are not described herein again.

Specifically, in step S904, the second connecting members are sequentially and directly connected to the corresponding first connecting members by suction, which are away from the display unit from the splicing mechanism. It will be appreciated that the second connector need not be pre-fixed to the splice mechanism.

It should be noted that, in the embodiment of the present application, after one of the display units is placed in a preset splicing area on the splicing mechanism and is fixed by the corresponding second connecting member, the next display unit is spliced until all the display units are spliced and fixed to the splicing mechanism; and after splicing of all the display units is finished, the splicing seam inspection is required, if the splicing seam at a certain position is found to be required to be adjusted, the corresponding second connecting piece can be directly moved away, then the position of the corresponding display unit is adjusted, and after the splicing seam adjustment is finished, the second connecting piece is connected with the corresponding first connecting piece in an adsorption manner from one side of the splicing mechanism, which is far away from the display unit.
