[0022] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiment of the utility model will be described in detail in conjunction with the drawings of the specification.

[0023] In the following description, many specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from the description, and those skilled in the art can make similar generalization without departing from the connotation of the utility model, therefore, the utility model is not limited by the following disclosed specific embodiments.

[0024] Secondly, the "one embodiment" or "embodiment" referred to herein is intended to mean a specific feature, structure, or characteristic under at least one implementation of the present application. The "in one embodiment" appearing in various places in the specification are not all referring to the same embodiment nor are they mutually exclusive of other embodiments.

[0025] Thirdly, the present application is described in detail in conjunction with the schematic diagram. In the detailed description of the embodiments of the present application, the cross-sectional view of the device structure is partially enlarged without the general proportion for the convenience of description, and the schematic diagram is only an example which should not limit the scope of protection of the present application. In addition, the three-dimensional spatial dimensions including length, width and depth should be included in the actual manufacture.

[0026] Embodiment 1

[0027] Referring to Figures 1-4 The embodiment provides a double-sided display LED invisible screen with transparent protection, comprising a substrate 100, a penetrating hole 101 is arranged on the substrate 100, and a splicing hole 102 is arranged at the edge of the substrate 100. The function is that two or more substrates are spliced left and right to form a complete penetrating hole, so that the splicing trace cannot be seen. A first lamp bead 103 with a driving chip is arranged on one side of the substrate 100, and a second lamp bead 104 with a driving chip is arranged on the other side of the substrate 100.

[0028] Specifically, the substrate 100 is a printed board, the penetrating hole 101 is circular, rhombic or square, and is arranged in an array mode on the substrate. The substrate 100 is provided with pads on both sides, and the first lamp bead 103 with a driving chip and the second lamp bead 104 with a driving chip are respectively welded on both sides of the substrate 100. The first lamp bead 103 with a driving chip and the second lamp bead 104 with a driving chip can be LED light tubes.

[0029] Further, since the substrate 100 is provided with the built-in driving chip lamp bead on both sides, in order to ensure that the lamp bead does not fall off during welding, the welding temperature of the lamp bead on the surface A of the substrate and the welding temperature of the surface B of the substrate must be different. For example, the lamp bead on the surface A is welded first, the solder paste and the welding temperature are 240 degrees, and when the lamp bead on the surface B is welded, the welding temperature is 200 degrees. In this way, the lamp bead on the surface A has been welded, and because the welding temperature is higher than that on the surface B, it will not melt and fall off.

[0030] The splicing hole 102 arranged at the side edge of the substrate 100 is half of the penetrating hole. Taking the circular penetrating hole as an example, the splicing hole 102 at the side edge of the substrate 100 is semicircular, and the splicing hole at the corner of the substrate 100 is quarter circular, so as to ensure that the complete penetrating hole structure is formed after splicing.

[0031] The substrate 100 is encapsulated with transparent resin 105.

[0032] Specifically, after the LED light emitting tube is pasted on the substrate 100, the LED light emitting tube part is immersed in a jig, the lamp is covered and wrapped together with the printed board by transparent resin glue, and then solidification is carried out. When the jig is taken out, the module is formed similar to the module protected by hard transparent glue, which can prevent collision, can prevent water splashing, and has high flatness.

[0033] The transparent resin 105 is provided with a threaded hole 105a.

[0034] Preferably, the threaded hole 105a is arranged at the splicing hole 102.

[0035] The two transparent resins 105 are spliced by the transparent material connecting piece 106, and the transparent material connecting piece 106 is fixed at the threaded hole 105a by a bolt.

[0036] It should be noted that the transparent material connecting piece 106 is provided with a through hole for the bolt to pass through.

[0037] The transparent material connecting piece 106 is a square plate, such as Figure 3 a square plate 106a.

[0038] The transparent material connecting piece 106 is a round plate, such as Figure 3 a round plate 106b.

[0039] The thread is made of transparent material.

[0040] Further, the transparent resins 105 on the left and right and above and below can also be interconnected by transparent resin glue, so that the gluing work is no longer needed, and glue pollution is avoided.

[0041] It should be understood that during the development of any actual implementation, such as in any engineering or design project, a large number of implementation decisions can be made. Such development efforts can be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, they will be a routine work of design, manufacture and production without excessive experiments.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalent, without departing from the spirit and scope of the technical solutions of the present application. They should be covered in the scope of the claims of the present application.
