DETAILED DESCRIPTION

[0033] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0037] Reference Figure 1-5 The first embodiment of the utility model provides a flexible LED module, the module includes a planar array driving board 1, hereinafter referred to as the panel 1, the thickness of the panel 1 does not exceed 0.5 mm, preferably 0.5 mm, so that its reliability and bendability can be correspondingly improved, and the weight can be reduced. In addition, the module also includes:

[0038] A connecting portion 2, which is fixedly connected to one side of the panel 1. Specifically, the connecting portion 2 may be a customized stud structure, such as a copper stud or an iron stud. In this embodiment, a copper stud is used;

[0039] The fixing part 3 has a receiving end 301 thereon, and the fixing part 3 is detachably connected to the connecting part 2. The fixing part 3 in this embodiment is a magnetic steel seat structure;

[0040] The magnetic core 4 is arranged in the container end 301 and is used to magnetically match with a carrier that needs to carry the module. The carrier refers to a structure such as a frame or a box. Here, the magnetic core 4 and the container end 301 can also be fixed by glue to improve the connection strength.

[0041] The support part 5 is a flexible structure and is closely arranged along the edge of one side of the panel 1. The support part 5 has a fitting surface 501, which is opposite to the side of the panel 1. The fitting surface 501 is used to support on the carrier. One side of the magnetic core 4 is flush with the fitting surface 501. The support part 5 can be a soft board silicone pad or a soft board rubber pad. In this embodiment, a soft board silicone pad is used;

[0042] Based on the above, by pasting a high-precision silicone rubber pad on the back of the panel 1, it can support the PCB of the panel 1. At the same time, the entire module contacts the box through the silicone rubber pad, and its thickness tolerance can be controlled within 0.1mm, which greatly reduces the height difference of the module splicing. Therefore, it can fully cope with the problem that due to the strong flexibility and high bending of the module, when splicing ultra-small radius arcs, the part without magnetic steel seat support will collapse downward, affecting the smoothness of the overall arc, and with the effect of the magnetic steel seat and the copper stud, it can fully reduce the situation that when splicing ultra-small radius arcs, the module corresponding to the extended edge has a large straight edge; and when the module is installed on the box, the distance between the magnetic core 4 and the box surface is basically consistent, and there will be no small distance in some areas, resulting in an increase in suction at this position; or a large distance in some areas, resulting in weak suction at this position; when splicing ultra-small radius arcs, a wave feeling of the screen will appear, so that the ribbed feeling and the convex feeling at the junction of the modules can be fully reduced on the screen;

[0043] After the soft board silicone pad is correctly pasted to the PCB board, install the high-precision customized external magnetic steel seat to the corresponding copper stud, and then install the magnetic core 4 into the corresponding magnetic steel seat groove;

[0044] After the magnetic base is installed in place, theoretically, its upper end surface is 0.25mm lower than the silicone rubber pad, so that when the screen is installed, the module contacts the box through the silicone pad; because the thickness tolerance of the silicone pad can be controlled within 0.1mm, the height difference caused by the installation of the screen is greatly reduced; the silicone rubber pad contacts the box, which will support the module and greatly reduce the wave feeling; at the same time, because the module contacts the box through the silicone pad during installation, the sliding friction between the two is large, so after the screen is installed, the module is not prone to sliding or displacement; compared with the existing technology, this product can better adapt to the assembly process of screens with extremely small radius sizes, and can be used in a wider range of scenarios;

[0045] Further, such as Figure 7 As shown, in order to achieve the splicing of ultra-small radius arcs, the module thickness needs to be reduced as much as possible. The smaller the module thickness, the easier it is to bend arcs with smaller radius. Regarding the specifications of the magnetic core 4, its size is φ8*1.2mm, and the thickness tolerance is controlled within 0.05mm.

[0046] Further, see Figure 4 and Figure 5The connecting portion 2 adopts a copper stud, and its structure can be divided into an integral groove end 201 and a plurality of guide claws 202. Specifically, a plurality of the guide claws 202 are distributed in a circular array on one side of the groove end 201. The guide claws 202 are used to be fixedly connected to one side of the panel 1. The guide claws 202 can increase the contact area with the panel 1, thereby increasing the stability of the connection.

[0047] Further, see Figure 4 and Figure 5 The fixing portion 3 also has a plug-in end 302 on one side, and the plug-in end 302 is threadedly matched with the slot end 201, thereby realizing a detachable connection between the entire copper stud and the magnetic steel seat.

[0048] Further, see Figure 3 and Figure 6 A soldering pad 101 is fixedly configured on one side of the panel 1, which maintains a one-to-one correspondence with the connecting part 2. In the connecting part 2, a plurality of the guide claws 202 and the soldering pad 101 are connected by welding, thereby further improving the connection stability. In addition, a groove is designed on the magnetic steel seat, so that a customized tool can be used for Z-axis adjustment, which facilitates the disassembly and assembly of the magnetic steel seat.

[0049] Further, see Figure 3 , a plurality of positioning holes 502 are evenly arranged on the support portion 5 along the edge path of the panel 1, and the number of the positioning holes 502 is consistent with that of the connecting portion 2, and the connecting portion 2 and the positioning holes 502 are kept consistent in position on one side of the panel 1; specifically, the support portion 5 is a soft board silicone pad, and a customized specification 3m9448a double-sided tape (single-sided release paper) is pasted on the back of the soft board silicone rubber pad (300x168.75), so the release paper can be torn off during actual assembly, and the positioning holes 502 are positioned with four-claw welded copper studs (single-sided design gap of 0.05mm) and then pasted on the ultra-soft board array driver board, without the need for special installation jigs, which greatly reduces the difficulty of assembly, and a diamond decorative pattern is evenly arranged on the fitting surface 501, which can increase the aesthetic effect.

[0050] Further, see Fig.10 The positioning hole 502 may include a front section 502a and a rear section 502b, the aperture of the rear section 502b is larger than that of the front section 502a, the diameter of the slot end 201 is consistent with the aperture of the front section 502a, and passes through the front section 502a to prevent a gap from forming between the two, thereby improving the positioning effect, the fixing portion 3 is located in the rear section 502b, and completely fills the rear section 502b, so that a part of the support portion 5 is clamped between the panel 1 and the magnetic steel seat in the thickness direction, thereby improving the connection stability of the support portion 5 on the panel 1.

[0051] Further, see Fig. 9The support portion 5 is evenly provided with a plurality of deformation guiding grooves 503 along its own path direction. When the panel 1 is bent as a whole, deformation can occur in the deformation guiding grooves 503, so that the module is bent evenly in multiple places, thereby avoiding uneven overall deformation.

[0052] For further information, please refer to Fig. 9 The deformation guiding groove 503 includes a first groove wall 503a and a second groove wall 503b. There are two first groove walls 503a, which are symmetrically distributed on both sides of the second groove wall 503b. An obtuse angle is formed between the first groove wall 503a and the second groove wall 503b. The second groove wall 503b is located in the middle of the thickness of the support part 5. Therefore, when the module is bent, the extrusion deformation direction of the rubber pad is between the two first groove walls 503a, and tends to bend toward the second groove wall 503b, rather than deforming around the module.

[0053] Further, see Fig.10 and Fig.11 The support portion 5 is configured with a draft angle at the edge, and the draft angle is 8°. At the same time, the outer dimensions of the soft board silicone pad are 0.5mm smaller than that of the single side of the PCB, reducing the installation or processing errors. When the modules are spliced ​​with inner and outer arcs, the modules are in contact with each other through the PCB, so that no obvious seams will appear.

[0054] Further, see Figure 1 The module also includes a magnetic sheet 6, which is arranged on one side of the panel 1. The magnetic sheet 6 can be quickly and accurately pasted into place through the silk-screen frame on the back of the PCB, and then the module can be maintained before disassembly and assembly through a special magnetic suction tool.

[0055] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
