Description

Technical Field

[0001] The present invention relates to the technical field of display devices, and in particular to an LED display lamp board structure and a double-sided display screen. Background Art

[0002] Traditional LED display screens usually adopt the method of vertically welding light-emitting diodes to the display lamp board. The display screen made in this way can only display on one side. If double-sided display is to be achieved, two sets of flat display boards need to be made back to back and stacked and assembled, which is not only complex in structure and high in cost, but also has the problem that it is difficult to balance permeability and sealing performance, restricting the development and application of double-sided display screens. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: to provide an LED display lamp board structure and a double-sided display screen, which can achieve a double-sided display effect through a special welding substrate and light-emitting diode design, while optimizing permeability and sealing performance and reducing costs.

[0004] To solve the above technical problem, the technical solution adopted by the present invention is: an LED display lamp board structure, including a welding substrate, a first light-emitting diode and a second light-emitting diode. The welding substrate has a welding surface. The first light-emitting diode is welded to one end of the welding surface and the optical axis of the first light-emitting diode is parallel to the welding surface. The second light-emitting diode is welded to the other end of the welding surface and the optical axis of the second light-emitting diode is parallel to the welding surface. The light-emitting surface of the first light-emitting diode faces away from the light-emitting surface of the second light-emitting diode.

[0005] To solve the above technical problem, the present invention also provides a double-sided display screen, including the above LED display lamp board structure.

[0006] The beneficial effects of the present invention are as follows: By making the optical axis of the light-emitting tube parallel to the welding surface and making the light-emitting surfaces of the two light-emitting tubes face in opposite directions, this structure can achieve double-sided display on a single welding substrate. Compared with the traditional single-sided display lamp board, it can achieve double-sided light emission on the same lamp board without additional components or complex assembly, improving the space utilization rate and display efficiency; traditional double-sided display screens usually require two sets of flat display boards to be made back-to-back and stacked and assembled, which is not only complex but also costly. The LED display lamp board structure of the present invention simplifies the overall structure and reduces the production cost by achieving double-sided display on a single welding substrate, reducing the number of required components and assembly steps; this design allows different display contents or the same display content to be set on both sides of the welding substrate to meet the requirements of different application scenarios. For example, in advertising displays, different advertisements can be shown on both sides; in information signs, the same information can be shown on both sides to improve visibility; since the optical axis of the light-emitting tube is parallel to the welding surface, the light can be more evenly distributed, reducing light loss and improving the brightness and uniformity of the display. At the same time, the design with light-emitting surfaces facing in opposite directions ensures good display effects in both directions, enhancing the overall visual experience; the light-emitting tubes are directly welded to the welding substrate, which is conducive to heat conduction and dissipation. The welding substrate can serve as a heat dissipation path to effectively dissipate the heat generated by the light-emitting tubes, thereby extending the service life of the light-emitting tubes and improving the reliability of the display lamp board; this LED display lamp board structure is applicable to various scenarios requiring double-sided display, such as indoor and outdoor billboards, information display screens, traffic signs, etc. Its flexible design can be adjusted according to actual needs to meet the requirements of different sizes and shapes, and has broad applicability and market competitiveness.

A driving circuit board 6 is installed in the driving frame 5. A conductive port 61 for electrically connecting to the welding substrate 1 is provided on the driving circuit board 6. A jack 521 is opened at a position of the second housing 52 corresponding to the conductive port 61; By making the optical axis of the light-emitting tube parallel to the welding surface and making the light-emitting surfaces of the two light-emitting tubes face in opposite directions, this structure can achieve double-sided display on one welding substrate 1. Compared with the traditional single-sided display panel, it can achieve double-sided light emission on the same display panel without additional components or complex assembly, improving the space utilization rate and display efficiency.

[0031] Preferably, the LED display lamp board structure further includes a packaging housing. The welding substrate 1 is encapsulated in the packaging housing by encapsulating glue. The light-emitting surfaces of the first light-emitting diodes 2 and the second light-emitting diodes 3 are exposed outside the packaging housing. It can be understood that by adding a packaging housing and encapsulating the welding substrate 1 therein while ensuring that the light-emitting surfaces of the light-emitting diodes are exposed, the protection of the welding substrate 1 and the light-emitting diodes is achieved, and the service life is extended. At the same time, this design improves the stability and reliability of the overall structure without increasing additional complexity. Specifically, the packaging housing includes a packaging bottom shell 4 and a packaging cover plate 41.

Encapsulating the LED chip with glue improves the stability and light-emitting efficiency of the light-emitting diode, while ensuring good electrical connection and protection effects. More specifically, a mounting bracket is further provided inside the mounting housing, and the LED chip is fixed to the mounting bracket. It is easy to understand that adding a mounting bracket inside the mounting housing is used to fix the LED chip. This design improves the mounting stability of the LED chip, ensures the performance and lifespan of the light-emitting diode, and provides a better heat dissipation path for the chip. Further, the material of the mounting bracket is a metal material, and both the LED chip and the conductive welding feet are welded to the mounting bracket. The mounting bracket is made of a metal material, and the LED chip and the conductive welding feet are welded to it. The use of the metal material not only enhances the structural stability but also improves the heat dissipation efficiency, extends the service life of the LED chip, and ensures good electrical conductivity.

Compared with the traditional single-sided display panel, this structure can achieve double-sided light emission on the same panel without additional components or complex assembly, improving space utilization and display efficiency. Traditional double-sided display screens usually require two sets of flat display panels to be fabricated back-to-back and assembled. This structure is not only complex but also costly.
