Mini LED refers to a light emitting device with a chip size of 100-300 μm, and Micro-LED refers to a light emitting device with a chip size of 100 μm or less. Micro light emitting diodes (Mini-LEDs/Micro-LEDs, MLEDs) can be used as self-luminous LEDs for display, and have the advantages of high brightness, high contrast, quick response and low power consumption, so that the display technology based on the MLEDs is increasingly widely applied in the display field. Specifically, thinning, miniaturization, and matrixing of the MLED display panel are achieved by integrating a high-density light emitting device array on a substrate.

With the rapid development of display technology, the spliced display device formed based on the MLED is widely applied to large-size display fields such as command monitoring centers, business centers, high-end conferences, private cinema and the like, and has wide application prospects. The method solves the technical problems of high cost and difficult maintenance of a single large screen, has extremely high expandability, and can be suitable for displaying images with various sizes.

In the related art, the tiled display device is formed by stitching a plurality of sub-display panel assemblies, and the sub-display panel assemblies are supported on the case. The sub display panel assembly may include a display substrate and a bracket for supporting the display substrate, but due to introduction of the bracket, on one hand, manufacturing cost is increased, and on the other hand, an adaptation structure for assembling the bracket and the display substrate is complicated, and design difficulty and installation difficulty are increased, so that a sub display panel assembly without the bracket is adopted at present.

Fig. 1 is a schematic structural view of a tiled display device provided in the related art, as shown in fig. 1, in which a sub-display panel assembly 1 without a bracket is used in the tiled display device, wherein a display substrate 11 includes a PCB substrate and a light emitting layer, and a driving structure for driving a light emitting device in the light emitting layer is disposed on the PCB substrate. Due to the limitation of the current manufacturing process, the thickness tolerance of the PCB substrate can only be controlled to be +/-0.15 mm, which results in the display substrate 11 having a thickness tolerance of 0-0.3mm, i.e., the flatness of the display substrate 11 cannot be ensured.

In view of the above problems, the flatness unevenness of the display substrate 11 is compensated for by performing a finishing process on the case 2 in the related art, thereby ensuring the flatness of the tiled display device after the sub-display panel assemblies 1 and the case 2 are tiled and assembled. However, the flatness of the sub-display panel assembly 1 cannot be adjusted by the scheme, and the process requirement on the box body 2 is extremely high, so that the installation difficulty is increased.

In order to solve at least one of the above technical problems, an embodiment of the present utility model provides a tiled display device, where a supporting structure is disposed on a sub-display panel assembly to ensure flatness of the tiled display device.

Fig. 2 and fig. 3 are schematic overall structures of a tiled display device according to an embodiment of the present utility model, fig. 4 is a schematic structural diagram of a box according to an embodiment of the present utility model, fig. 5 is a schematic structural diagram of a sub-display panel assembly according to an embodiment of the present utility model, and fig. 6 is a schematic planar structural diagram of a first surface of a display substrate according to an embodiment of the present utility model.

As shown in fig. 2 and 3, the tiled display device provided in the embodiment of the utility model includes a case 200 and at least one sub-display panel assembly 100, where the sub-display panel assembly 100 includes a display substrate 1 and a plurality of support structures 2.

As shown in fig. 5, the display substrate 1 has a first face 1a and a second face 1b disposed opposite to each other; the support structures 2 are located on the first face 1a, each of the plurality of support structures 2 has a contact face 2a remote from the display substrate 1, and the distance D between the contact face 2a and the second face 1b of each support structure 2 is equal.

As shown in fig. 4, the case 200 includes a bottom plate 5 and a bearing portion 6 on the bottom plate 5, wherein a plurality of accommodating grooves 7 are provided at an end of the bearing portion 6 away from the bottom plate 5, and the accommodating grooves 7 are configured to accommodate the support structure 2 such that a contact surface 2a of the support structure 2 is in contact with a bottom surface of the accommodating groove 7 on a side close to the bottom plate 5.

In the tiled display device provided by the embodiment of the utility model, a plurality of support structures 2 are arranged on the first surface 1a of the display substrate 1 in the sub-display panel assembly 100, and the contact surfaces 2a of the plurality of support layer structures are arranged to be equal to the distance between the second surface 1b of the display substrate 1 so as to control the thickness tolerance of the sub-display panel assembly 100; for different sub-display panel assemblies 100, when the thickness of the display substrate 1 is different, the uniformity of the overall thickness (the distance between the contact surface 2a of the support structure 2 and the second surface 1b of the display substrate 1 in the sub-display panel assembly 100) of the different sub-display panel assemblies 100 can be improved by adjusting the height of the support structure 2 on the first surface 1a of the display substrate 1; when the sub-display panel assemblies 100 with the same thickness are assembled on the case 200, the second faces 1b of the display substrates 1 in the respective sub-display panel assemblies 100 may be in the same plane or substantially in the same plane, that is, the respective sub-display panel assemblies 100 have better flatness, which is beneficial to improving the display effect and the splice assembly yield. Further, the accommodating groove 7 for accommodating the supporting structure 2 is provided on the bearing portion 6 of the case 200, so that the sub-display panel assembly 100 can be assembled on the case 200 in a sinking manner, and the flatness of the tiled display device is improved while the overall thickness of the tiled display device is reduced.

Meanwhile, compared with the mode of adjusting the flatness of the spliced display device by finishing the bracket or the box body 200 in the related art, the manufacturing cost is saved, and the manufacturing and assembling difficulties are reduced.

It should be noted that, the equal distance between the contact surface 2a and the second surface 1b of each supporting structure 2 refers to that the tolerance of the distance between the contact surface 2a and the second surface 1b of any two supporting structures 2 is ±0.02mm, so as to ensure that the second surface 1b of the display substrate 1 in the sub-display panel assembly 100 may be in the same plane or substantially in the same plane. The first surface 1a of the display substrate 1 may be a non-light-emitting surface, and the second surface 1b may be a light-emitting surface, and the support structure 2 is provided on the non-light-emitting surface, i.e., the first surface 1a, without affecting the light-emitting surface of the display substrate 1.

In some embodiments, the material of the supporting structures 2 includes at least one of copper and stainless steel, so as to grind the plurality of supporting structures 2, so that the distance between the contact surface 2a and the second surface 1b of each supporting structure 2 is equal, thereby improving the flatness of the tiled display device.

In some embodiments, as shown in fig. 5, the display substrate 1 includes a PCB substrate 11 and a light emitting layer 12 on the PCB substrate 11; the surface of the PCB substrate 11 far away from the light emitting layer 12 is a first surface 1a, a plurality of bonding pads (not shown in the figure) are disposed on the first surface 1a, and the supporting structure 2 is located on the corresponding bonding pads, that is, the supporting structure 2 and the display substrate 1 are fixed in a welded connection manner, and distances between the contact surfaces 2a of the plurality of supporting structures 2 and the second surface 1b of the display substrate 1, that is, the light emitting side surface of the light emitting layer 12 are equal.

In some embodiments, as shown in fig. 5, the display substrate 1 may further include a protective film 13 on a side of the light emitting layer 12 remote from the PCB substrate 11, wherein the light emitting layer 12 includes a plurality of light emitting devices. The protective film 13 covers part of the surfaces of the plurality of light emitting devices while filling the gap regions of the plurality of light emitting devices. In one example, the protective film 13 includes a transparent material, and then the protective film 13 may cover a surface of the light emitting layer 12 on a side remote from the PCB substrate 11. In another example, the protective film 13 may be made of black silica gel or black resin, and in this case, a plurality of hollowed-out portions are disposed on the protective film 13, and the hollowed-out portions expose the light emitting area of the light emitting device, that is, the protective film 13 does not affect the light emitting of the light emitting device. By arranging the protective film 13, a plurality of light emitting devices can be protected, and the light emitting devices are prevented from being damaged in the process of manufacturing, such as being corroded by water and oxygen; in addition, the display contrast of the sub display panel assembly 100 in a scene where ambient light is strong, such as outdoors, may be improved.

It should be understood that the thickness uniformity of the protective film 13 is good during the fabrication of the sub-display panel assembly 100, and the thickness tolerance of the light emitting substrate composed of the PCB substrate 11 and the light emitting layer 12 is within ±0.15mm, the limit tolerance of the entire display substrate 1 is 0.3mm. Whereas the light emitting devices in the display substrate 1 are MLEDs, the chip size of which does not exceed 0.3mm at maximum, and thus tolerances on the display substrate 1 will cause dark seams in the display screen of the display substrate 1. Based on this, the support structure 2 is provided on the first face 1a of the display substrate 1, making up for the thickness differences occurring on the display substrate 1.

In the tiled display device, the case 200 carries a plurality of sub-display panel assemblies 100, each sub-display panel assembly 100 corresponds to one installation area a on the bottom plate 5 of the case 200, that is, as shown in fig. 4, the bottom plate 5 of the case 200 is divided into a plurality of installation areas a, and a sidewall 60 corresponding to each installation area a is provided on the bottom plate 5 along the edge of each installation area a; the carrier 6 comprises a side wall 60. When the sub display panel assembly 100 is assembled with the case 200, the edges of the sub display panel assembly 100 are placed on the sidewalls 60 to achieve load bearing support of the sub display panel.

In the embodiment of the utility model, the distances between the contact surfaces 2a of the plurality of support structures 2 and the second surface 1b of the display substrate 1 are kept uniform, that is, the sum of the thicknesses of the support structures 2 and the display substrate 1 is uniform. However, the display substrate 1 has a problem of uneven thickness due to the process limitation of the PCB substrate 11, and thus, the heights of the different support structures 2 themselves are also different. In some embodiments, the height h of the support structure 2, i.e. the distance h between the contact surface 2a of the support structure 2 and the first surface 1a of the display substrate 1, is 4-7mm to compensate for thickness non-uniformities present on the display substrate 1.

It should be appreciated that the support structure 2 is too small in height and the display substrate 1 is easily damaged during the polishing process operation; the support structure 2 has an excessive height and the stability of the case 200 is poor when assembled. Based on this, it was verified through many experiments that the reserved height of the support structure 2 was set to 5mm. Specifically, in one example, a plurality of support structures 2 with a height of 5mm are reserved on the first surface 1a of the display substrate 1, after the plurality of support structures 2 are processed through a grinding process, the flatness of the sub-display panel assembly 100 is ensured while the display substrate 1 is not damaged, and at least one sub-display panel assembly 100 with better flatness is placed on the case 200, so that a tiled display device with better stability is formed.

In some embodiments, the bottom surfaces of all the receiving grooves 7 lie on the same preset plane, which is parallel to the plane in which the bottom plate 5 lies. That is, the case 200 itself has a good flatness, and when the supporting structure 2 is placed in the accommodating groove 7, that is, the contact surface 2a of the supporting structure 2 contacts the bottom surface of the accommodating groove 7, the sub-display panel assembly 100 with the thickness compensated by the plurality of supporting structures 2 has a good flatness; on the other hand, the bottom surfaces of the accommodating grooves 7 are on the same plane, so that the overall flatness of the tiled display device can be ensured.

Further, since the bottom surfaces of all the receiving grooves 7 are located on the same plane, that is, the groove depths of all the receiving grooves 7 are uniform, but the heights of different support structures 2 are not uniform, the sinking depths of the support structures 2 in the receiving grooves 7 are not uniform when the support structures 2 are placed in the receiving grooves 7. Based on this, in some embodiments, the difference between the height of the supporting structure 2 and the groove depth of the corresponding receiving groove 7 is in the range of 0 to 1mm to form a sinking adjustment space, ensuring the overall flatness of the tiled display device.

Specifically, the case 200 may be subjected to a computer numerical control machine (Computerised Numerical Control Machine, CNC) process to form a plurality of accommodating grooves 7 having uniform groove depths on the side walls 60 thereof.

In some embodiments, the supporting structure 2 is plate-shaped, and the plate-shaped supporting structure 2 is perpendicular to the plane where the display substrate 1 is located, so that when the sub-display panel assembly 100 is assembled with the case 200, the plate-shaped supporting structure 2 is inserted into the groove of the side wall 60 of the bearing portion 6 of the case 200, so as to realize submerged assembly, and reduce the thickness of the tiled display device under the condition that the flatness of the tiled display device is consistent.

In some embodiments, as shown in fig. 6, the plurality of support structures 2 are evenly distributed over the edge of the first face 1 a. Specifically, the first surface 1a is a rectangular surface, and the sub-display panel assembly 100 includes 8 support structures 2, the 8 support structures 2 being distributed at four corners of the rectangular surface, and an intermediate position of each side of the rectangular surface.

In some embodiments, the support structure 2 at the corners of the rectangular surface includes two support plates 20 vertically disposed, and the two support plates 20 are connected as a unitary structure, thereby enabling improved stability between the case 200 and the sub-display panel assembly 100.

Specifically, in one example, the support structures 2 distributed at the middle position of each side of the rectangular surface are plate-shaped structures with the length of 13mm, the width of 2mm and the height of 5 mm; the specific sizes of the two supporting plates distributed on the four corner bottom plates of the rectangular surface are 2mm in width, 5mm in height and 6.5mm in length.

In some embodiments, as shown in fig. 1 and 6, the tiled display device further includes: a plurality of first magnetic members 3 and a plurality of second magnetic members (not shown in the figure).

The first magnetic component 3 is located on the first surface 1a, and a distance between a side surface of the first magnetic component, which is far away from the display panel, and the second surface 1b is smaller than a distance between the contact surface 2a of the supporting structure 2 and the second surface 1b, that is, the first magnetic portion does not protrude from the supporting structure 2, so that the flatness of the sub-display panel assembly 100 is not affected.

The second magnetic member is located at a side of the bottom plate 5 of the case 200 facing the sub display panel assembly 100, and both the first magnetic member 3 and the second magnetic member are configured to be magnetically attracted to fix the sub display panel assembly 100 to the case 200.

It should be understood that, during the assembly process of the case 200 and the sub-display panel assembly 100, the case 200 is a finished surface, and the flatness is good, and the sub-display panel assembly 100 does not need to be completely contacted with the supporting surface of the case 200, but only needs to contact the contact surfaces 2a of the plurality of supporting structures 2 in the sub-display panel assembly 100 with the bottom surface of the accommodating groove 7 on the case 200; meanwhile, the second magnetic member on the case 200 is magnetically coupled with the first magnetic member 3 in the sub display panel assembly 100 to provide a sufficient attraction force to achieve a stable connection of the sub display panel assembly 100 and the case 200.

It should be noted that, the first magnetic component 3 and the second magnetic component may be in contact or not in contact, and based on the magnetic attraction characteristic of the magnetic components, even if the first magnetic component and the second magnetic component are not in contact, the magnetic attraction matching can not be affected, so that the magnetic components can be prevented from affecting the height of the sub-display panel assembly 100, and the flatness of the spliced display device is ensured.

In some embodiments, as shown in fig. 6, a plurality of conductive terminals 41 are further disposed on the first surface 1a of the display substrate 1, and the conductive terminals 41 are configured to conduct out Static electricity generated on the display substrate 1, so as to prevent the display substrate 1 from being affected by electrostatic Discharge (ESD). In one example, the bottom plate 5 of the case 200 is provided with conductive posts (not shown in the figure) corresponding to the conductive terminals 41, and static electricity led out by the conductive terminals 41 can be further discharged through the conductive posts on the case 200, so as to ensure the ESD protection effect of the tiled display device.

As shown in fig. 6, a connector terminal 42 may be provided on the first surface 1a of the display substrate 1. The driving structure in the PCB substrate 11 may include a flexible circuit board and a driving circuit board, and the connector terminal 42 is configured to connect the flexible circuit board and the driving circuit board.

It is to be understood that the above embodiments are merely illustrative of the application of the principles of the present utility model, but not in limitation thereof. Various modifications and improvements may be made by those skilled in the art without departing from the spirit and substance of the utility model, and are also considered to be within the scope of the utility model.
