Description

Spliced display device and manufacturing method thereof

Technical Field

The application relates to the technical field of display, in particular to a spliced display device and a manufacturing method thereof.

Background

Micro-LEDs are technologies in which Micro-LEDs (light emitting diode, light emitting diodes) are used as light emitting pixel units, and are assembled with a driving module to form a high-density display array. Compared with display technologies such as an LCD (Liquid Crystal Display ), an OLED (Organic Light-Emitting Diode), and the like, the Micro-LED has cross-generation advantages in terms of 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, meeting rooms, stadiums, and the like. The existing large screen display mainly has four design schemes: the first scheme is an LCD spliced screen, which has lower cost, but can only be applied indoors and has obvious spliced seams; the second scheme is a PCB (Printed Circuit Board ) small-space LED spliced screen, which can realize seamless splicing and highlighting, but has lower PPI and huge and complex module; the third scheme is projection display, the brightness of the scheme is very low, the picture is unclear, the image is easy to deform, and the scheme can only meet the general indoor office; the fourth scheme is a glass-based Mini-LED spliced screen, and the scheme can realize seamless splicing, highlight and high PPI display, and is light, thin and attractive, and has the defects of obvious granular feel and unfavorable close-range viewing.

However, micro-LED display technology is mainly applied to two fields of Micro display and large screen display at present because of cost. However, due to the limitation of a huge amount of transfer machines, the Micro-LED large screen display can only be realized by splicing. Since the Micro-LED display has very small pixel pitch, the total error allowed in the stitching is required to be very small, otherwise, it is difficult to realize seamless stitching display. The existing Micro-LED large screen display technology has serious joint problems because of the processing error of a joint mechanism and the lack of a joint adjusting mechanism, and even causes mutual collision damage between Micro-LED display units during the joint.

At present, the Micro-LED large screen display technology has serious joint problems because of the processing error of a joint mechanism and the lack of a joint adjusting mechanism, and even causes mutual collision damage among Micro-LED display units during the joint. In general, the common methods for improving the seam of a Micro-LED tiled display device are as follows: the first method is to improve the precision of the splicing mechanism, the method has high cost, the larger the splicing mechanism is, the more difficult the precision is ensured, and the infinite splicing of the large screen can not be realized; the second method is that the splicing mechanism is regulated by a screw, in the method, the splicing mechanism is huge and complex, and the larger the size is, the more difficult the precision is ensured; 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 of an exemplary tiled display device 1', and fig. 2 is a top view of a tiled mechanism 2' in the tiled display device 1' provided in fig. 1. The exemplary tiled display device 1 'includes 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 magnet attraction mechanism 4' comprises a magnet sheet 5' arranged on the back (one side close to the splicing mechanism 2 ') of the corresponding Micro-LED display unit 3', and a fixed magnet 6' embedded on the splicing mechanism 2' and in corresponding magnet attraction connection with the magnet sheet 5 '. Wherein, magnet piece 5 'and Micro-LED display element 3' fixed connection, and fixed magnet 6 'and concatenation mechanism 2' fixed connection.

When the spliced 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 quickly fixed on the splicing mechanism 2 'under the action of the magnetic attraction force of the magnet sheet 5' and the fixed magnet 6', so that the position of the Micro-LED display unit 3' is easily deviated due to the fact that the position is not adjusted, and a spliced seam is generated; in addition, since 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', if the splicing seam is to be adjusted, an acting force larger than the 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', and the Micro-LED display unit 3 'is easily damaged in the process, or the Micro-LED display units 3' are mutually collided to be damaged.

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

Example 1

As shown in fig. 3 to 5, an embodiment of the present application provides a tiled display device 1, the tiled display device 1 including a tiled mechanism 2, a plurality of display elements 3, and a plurality of connection mechanisms 4.

Specifically, as shown in fig. 4 and 5, the splice mechanism 2 has a plurality of splice areas 5 adjacent to each other; and each splicing area 5 is provided with a limiting through hole 6 penetrating the splicing mechanism 2. Specifically, the stitching mechanism 2 has a first surface 7 and a second surface 8 disposed opposite to each other, wherein the first surface 7 is used to stitch the plurality of display units 3. It will be appreciated that the limiting through hole 6 extends through 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 splice mechanism 2 includes any one of a rectangle and a circle, although not limited thereto.

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

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

Specifically, the display unit 3 is a display screen, such as a Micro-LED display screen, but is not limited thereto. In a specific embodiment, each display unit 3 may be independently displayed, which is, of course, not limited thereto.

Specifically, as shown in fig. 4, the plurality of connection mechanisms 4 are disposed in one-to-one correspondence with the plurality of display units 3, and are used for fixing the plurality of display units 3 on the splicing mechanism 2. Wherein the connecting mechanism 4 comprises a first connecting piece 9 and a second connecting piece 10; the first connecting piece 9 is fixedly connected to one side of the corresponding display unit 3 close to the splicing mechanism 2 and is positioned in the corresponding limiting through hole 6; the second connecting piece 10 is located at one side of the first connecting piece 9 away from the display unit 3, is detachably connected with the first connecting piece 9 in an adsorption mode, and is movably connected with the splicing mechanism 2.

It should be noted that the movable connection of the second connecting member 10 with the splicing mechanism 2 means that the second connecting member 10 is in contact with a surface (e.g., the second surface) of the splicing mechanism 2, but is not fixedly connected.

Specifically, the second connecting piece 10 is movably connected with one side of the splicing mechanism 2 away from the display unit 3.

In one embodiment, the first connector 9 is a piece of iron and the second connector 10 is a piece of magnet. In another embodiment, the first and second connection members 9 and 10 are each magnet blocks. It will be appreciated that the first connector 9 and the second connector 10 are attached by magnetic attraction.

In a specific embodiment, the radial width of the first connecting piece 9 (the width in the direction parallel to the first surface 7) is smaller than the aperture of the corresponding limiting through hole 6, so that the first connecting piece 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 limit through hole 6; the second connecting piece 10 is close to one side of the first connecting piece 9 and is attached to one side of the first connecting piece 9 and the splicing mechanism 2 away from the display unit 3. It will be appreciated that the second connector 10 in the embodiment of the present application is located on the side of the splicing mechanism 2 away from the display unit 3, i.e. protrudes from the second surface 8 of the splicing mechanism 2, so that the second connector 10 is more convenient to grasp during installation and removal.

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

In particular, the radial cross-sectional shape of the first and second connection members 9 and 10 may be circular or rectangular, but may be other shapes, without limitation.

In the process of manufacturing the tiled display device 1, a manner of first stitching and then adsorbing (for example, magnetic attraction) fixing 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 the corresponding splicing area 5 on the splicing mechanism 2, so that the first connecting piece 9 at the back (opposite to the light emitting surface) of the display unit 3 is positioned in the corresponding limiting through hole 6, and after the position of the display unit 3 is adjusted, the corresponding second connecting piece 10 is correspondingly adsorbed and connected with the first connecting piece 9 from the side, away from the display unit 3, of the splicing mechanism 2, so that the m 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 on the splicing mechanism 2, the first connecting piece 9 on the back of the display unit 3 is located 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, and finally the corresponding second connecting piece 10 is in corresponding adsorption connection with the first connecting piece 9 from the side, away from the display unit 3, of the splicing mechanism 2, so that the (m+1) th display unit 3 is fixed on the splicing mechanism 2. By the above method, a plurality of display units 3 can be sequentially spliced and fixed on the splicing mechanism 2 to form a large-sized spliced display device 1 (large-screen display device). If the seam is found to be adjusted after the splicing is completed, the corresponding second connecting piece 10 can be directly moved away, then the position of the corresponding display unit 3 is adjusted, and after the seam adjustment is completed, the second connecting piece 10 is placed on one side of the corresponding limiting through hole 6 far away from the display unit 3, so that the second connecting piece is in adsorptive connection with the first connecting piece 9.

It can be understood that when adjusting the seam of the tiled display device 1 in the embodiment of the present application, the corresponding second connecting piece 10 needs to be removed first, and then the position of the display unit 3 is adjusted without resistance, so as to realize the adjustment of the seam; the process can avoid the problem that the display units 3 are damaged or the adjacent display units 3 collide with each other to be damaged due to the adoption of strong adjustment of the seam.

In the embodiment of the application, the splicing mechanism 2 has simple structural design and low cost, not only can realize infinite screen splicing technology, but also can realize flexible adjustment of the splicing seams, and ensures seamless splicing; in addition, as the splicing mechanism 2 is movably connected with the second connecting piece 10 (for example, a magnet block) and the display units 3 are spliced in a mode of splicing firstly and then adsorbing and fixing, the application can avoid the problem that the display units 3 are damaged or the adjacent display units 3 collide with each other to be damaged due to the adoption of strong adjustment of the splicing seam; therefore, the application can improve the seam of the spliced display device 1, realize seamless spliced display, realize infinite screen splicing technology, improve the display quality of the large-size spliced display device 1 and improve the competitiveness and market share of products.

Example two

As shown in fig. 3 and 6, the embodiment of the present application further provides a tiled display device, which is different from the previous 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 larger than the radial width of the first connecting portion 11; the first connecting part 11 is located in the limiting through hole 6 and is detachably connected with one side, far away from the display unit 3, of the first connecting piece 9, and the second connecting part 12 is located on one side, far away from the display unit 3, of the splicing mechanism 2 and is movably connected with the splicing mechanism 2.

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

It can be appreciated that in the embodiment of the present application, the thickness of the first connecting piece 9 is smaller than the depth of the limiting through hole 6, and the total thickness of the first connecting portion 11 of the first connecting piece 9 and the second connecting piece 10 is equal to the depth of the limiting through hole 6; the second connecting part 12 of the second connecting piece 10 protrudes out of the second surface 8 of the splicing mechanism 2, so that the second connecting piece 10 is more convenient to grasp during installation and disassembly.

Specifically, the radial cross-sectional shapes of the first connecting portion 11 and the second connecting portion 12 may be circular or rectangular, but may be other shapes, and are not limited thereto.

Specifically, in the process of splicing the display unit 3, after the position of the display unit 3 on the first surface 7 of the splicing mechanism 2 is adjusted, the first connection portion 11 of the second connection member 10 may be directly inserted into the corresponding limiting through hole 6 from the side of the splicing mechanism 2 away from the display unit 3, so that the first connection member is in adsorptive connection with the corresponding first connection member 9. When the seam of the spliced display device 1 is adjusted, the first connecting part 11 of the second connecting piece 10 is firstly pulled out of the corresponding limiting through hole 6, then the position of the corresponding display unit 3 is adjusted, and finally the first connecting part 11 of the second connecting piece 10 is reinserted into the corresponding limiting through hole 6, so that the first connecting piece 11 is in adsorption connection with the corresponding first connecting piece 9.

Example III

As shown in fig. 3 and 7, the embodiment of the present application further provides a tiled display device, which is different from the first and second embodiments in that each of the limiting through holes 6 includes a first sub-limiting through hole 13 and a second sub-limiting through hole 14 that are stacked, and the aperture of the second sub-limiting through hole 14 is larger than that of the first sub-limiting through hole 13; the first connecting piece 9 is positioned in the first sub limiting through hole 13, the radial width of the first connecting piece 9 is smaller than the aperture of the first sub limiting through hole 13, and the thickness of the first connecting piece 9 is equal to the depth of the first sub limiting through hole 13; the second connecting piece 10 is at least partially located in the second sub-limiting through hole 14, and the radial width of the second connecting piece 10 located in the second sub-limiting through hole 14 is greater than the aperture of the first sub-limiting through hole 13 and less than or equal to the aperture of the second sub-limiting through hole 14.

In a specific 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 reducing the overall thickness of the tiled display device 1. It will be appreciated that the thickness of the second connector 10 is less than or equal to the depth of the second sub-limit through hole 14. Since the second connector 10 does not protrude from the second surface 8 of the splice mechanism 2, the second connector 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 near 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 unit 3, after the position of the display unit 3 on the first surface 7 of the splicing mechanism 2 is adjusted, the second connecting piece 10 may be directly inserted into the corresponding second sub-limiting through hole 14 from the side of the splicing mechanism 2 away from the display unit 3, so that the second connecting piece is in adsorption connection with the corresponding first connecting piece 9. When the seam of the spliced display device 1 is adjusted, the second connecting piece 10 is firstly pulled out of 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 so as to be in adsorption connection with the corresponding first connecting piece 9.

Of course, in other embodiments, the second connector 10 may also protrude from the second surface 8 of the splicing mechanism 2, so that the second connector 10 is more convenient to grasp during installation and removal.

Example IV

As shown in fig. 3 and 8, the embodiment of the present application further provides a tiled display device, which is different from the third embodiment in that the second connector 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 larger than the radial width of the first connecting portion 11; the first connecting part 11 is located in the second sub limiting through hole 14 and is detachably connected with one side, far away from the display unit 3, of the first connecting piece 9, and the second connecting part 12 is located on one side, far away from the display unit 3, of the splicing mechanism 2 and is movably connected with the splicing mechanism 2.

It will be appreciated that 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 is more convenient to grasp during installation and removal.

Example five

As shown in fig. 9, the embodiment of the present application further provides a method for manufacturing the tiled display device in any of the foregoing embodiments, including steps S901 to S904.

Step S901, providing a splicing mechanism having a plurality of splicing regions adjacent to each other; wherein each splicing area is provided with a limiting through hole penetrating through the splicing mechanism;

step S902, providing a plurality of display units and a plurality of connecting mechanisms; the connecting mechanism comprises a first connecting piece and a second connecting piece, and the first connecting piece is fixedly connected to the back of the corresponding display unit in advance;

step S903, sequentially splicing and placing a plurality of display units with first connecting pieces on the back on a splicing mechanism, so that the display units are arranged in one-to-one correspondence with the splicing areas, and the first connecting pieces are positioned in the corresponding limiting through holes; and

step S904, fixing a plurality of display units on the splicing mechanism through second connectors of the plurality of connecting mechanisms to form a spliced display device; the second connecting piece is located at one side of the first connecting piece far away from the display unit, is detachably connected with the first connecting piece in an adsorption mode, and is movably connected with the splicing mechanism.

In particular, 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 connection members are directly connected to the corresponding first connection members in an adsorption manner in order from the splicing mechanism to the display unit. It will be appreciated that the second connector need not be pre-secured to the splice mechanism.

It should be noted that, in the embodiment of the present application, after one display unit is placed in a preset splicing area on the splicing mechanism, the next display unit is spliced after being fixed by a corresponding second connecting piece until all the display units are spliced and fixed on the splicing mechanism; after the splicing of all the display units is completed, the splice inspection is required, if the splice 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 splice adjustment is completed, the second connecting piece is adsorbed and connected with the corresponding first connecting piece from one side, far away from the display unit, of the splicing mechanism.

A method of manufacturing a tiled display device according to the third embodiment will be described as an example. As shown in fig. 10, the display unit 3 with the first connecting piece 9 at the back is placed in one splicing area 5 on the splicing mechanism 2, so that the first connecting piece 9 is located in the corresponding first sub-limiting through hole 13; then, the second connecting piece 10 is inserted into the corresponding second sub limiting through hole 14 from one side of the splicing mechanism 2 away from the display unit 3, so that the second connecting piece 10 is in adsorption connection with the corresponding first connecting piece 9, and the display unit 3 is fixed at a preset position of the splicing mechanism 2; the foregoing steps are then repeated to sequentially fix the remaining display units 3 to the corresponding stitching regions 5 on the stitching mechanism 2, so that the plurality of display units 3 are stitched and fixed on the stitching mechanism 2, forming the stitched display device 1 as shown in fig. 3. Of course, after the splicing is completed, the splice between the display units 3 needs to be checked, if the splice at a certain position needs to be adjusted, the corresponding second connecting piece 10 is directly moved out of the second sub-limiting through hole 14, then the position of the corresponding display unit 3 is adjusted, so that the splice is adjusted, and after the splice is adjusted, the second connecting piece 10 is inserted into the corresponding second sub-limiting through hole 14.
