Description

Technical Field

[0001] This invention relates to the field of LED display technology, and specifically to an LED display structure and manufacturing method integrating solar cells. Background Technology

[0002] Existing solar-powered LED displays are mostly designed with a split structure, where the solar panel is only placed on the side of the display as an independent power supply component. This structure has several problems: First, it occupies a large space, is thick and heavy, and has poor installation adaptability, failing to meet the application requirements of lightweight and thin designs. Second, the side-mounted display easily blocks the sunlight-receiving surface of the solar panel, resulting in a significant reduction in the solar panel's power generation efficiency. Third, LED displays lack a natural background, resulting in low contrast during the day and requiring high brightness operation, leading to high energy consumption. Therefore, there is an urgent need for a solar-powered LED display that can meet the application requirements of lightweight and thin designs, improve photoelectric conversion efficiency, and enhance the equipment's weather resistance and lifespan. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention aims to provide an LED display structure with integrated solar cells, which can reduce the overall size, thickness and weight of the structure, meet the application requirements of lightweight and thinness, improve photoelectric conversion efficiency, and enhance the weather resistance and service life of the device.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: an LED display structure with integrated solar cells, including a solar cell layer and a first LED display layer, wherein the solar cell layer includes a first transparent protective layer, a solar cell and a second transparent protective layer, the solar cell is bonded between the first transparent protective layer and the second transparent protective layer, the first LED display layer is encapsulated on the outside of the second transparent protective layer with transparent potting compound, and includes a first transparent light board and a first LED light, wherein the first LED light is soldered to the first transparent light board.

[0005] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This display screen structure integrates the solar cell layer and the first LED display layer into one piece, adopting a layered integrated structure, which can significantly reduce the overall volume, thickness and weight of the LED display screen, making installation more convenient, adapting to a variety of installation scenarios, and better meeting the application requirements of lightweight and thin design; 2. In this display structure, the first LED display layer is placed outside the second transparent protective layer. The dark solar cell layer can be used as the natural background of the LED display, which greatly improves the daytime display contrast. It does not require high brightness operation, which can save energy and achieve self-sufficiency and efficient use of energy. 3. The first transparent protective layer, the second transparent protective layer, the first transparent lamp panel, and the transparent potting compound on the outside of the solar cell are all designed with high transmittance, so that they will not block the light received by the solar cell layer from any direction. This not only reduces the angle requirements during installation and improves the convenience of installation, but also further ensures the photoelectric conversion efficiency. 4. In this display screen structure, the first LED display layer is encapsulated on the outside of the second transparent protective layer with transparent potting compound. This not only does not block the solar cell layer from receiving light, but also improves the sealing performance, effectively preventing problems such as delamination, water ingress, and scratches, and improving the weather resistance and service life of the equipment. 5. This display screen features an integrated structure design, eliminating the need for complex on-site splicing and debugging. The size can be customized according to actual needs, allowing for direct on-site installation and significantly improving installation efficiency.

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below: Example 1 Reference Figure 1 Embodiment 1 of the present invention provides an LED display structure with integrated solar cells, including a solar cell layer 100 and a first LED display layer 200. The solar cell layer 100 includes a first transparent protective layer 110, a solar cell 120 and a second transparent protective layer 130 arranged sequentially.

[0020] The first transparent protective layer 110 and the second transparent protective layer 130 are dedicated protective layers for the solar cell 120. They can be rigid or flexible protective layers with high transparency, scratch resistance, and good weather resistance, such as transparent glass substrates or transparent flexible substrates. The solar cell 120 is bonded between the first transparent protective layer 110 and the second transparent protective layer 130, and is reliably protected by them from external environmental corrosion. Furthermore, the solar cell 120 is bonded between the first transparent protective layer 110 and the second transparent protective layer 130 using a transparent adhesive 400. The transparent adhesive 400 serves as the core structure for interlayer bonding of the solar cell layer 100, and can be used for bonding the solar cell 120 to the first transparent protective layer 110 and the second transparent protective layer 130. It possesses high light transmittance and high bonding strength, and has no risk of yellowing or delamination, while also ensuring tight interlayer adhesion. The solar cell 120 is the core power generation component of the entire LED display structure. It also serves as the background layer of the LED display structure. High photoelectric conversion efficiency solar cells are selected, and the color is dark, which can improve the daytime display contrast of the LED display structure. It can be combined with rigid or flexible substrates to form a rigid solar cell layer 100 or a flexible solar cell layer 100 to adapt to different installation requirements.

[0021] The first LED display layer 200 includes a first transparent light panel 210 and a first LED lamp 220. The first transparent light panel 210 serves as the basic carrier of the first LED display layer 200 and is made of a high-transmittance flexible substrate. When the solar cell 120 is combined with the flexible substrate to form a flexible solar cell layer 100, the flexible light panel can be bent synchronously with the flexible solar cell layer 100, adapting to curved surfaces and irregular shapes. The surface can be arranged with LED lamps according to a preset resolution. The first LED lamp 220 is a display light-emitting component soldered onto the first transparent light panel 210. It adopts a surface-mount small package to ensure the overall light transmittance of the first LED display layer 200, without blocking the light received by the solar cell 120, and without affecting the photoelectric conversion efficiency. The first LED display layer 200 is encapsulated on the outside of the second transparent protective layer 130 with transparent potting compound 500 to achieve sealing and protection of the LED display layer, while ensuring the light transmittance of the LED display layer. The transparent potting compound 500 has good adhesion, which can improve the stability of the overall structure. When the solar cell 120 is combined with a flexible substrate to form a flexible solar cell layer 100, the transparent potting compound 500 is also combined with a flexible potting compound.

[0022] Compared to existing technologies that separate the solar panel onto one side of the LED display screen, this display screen structure integrates the solar cell layer 100 and the first LED display layer 200 into a single, layered integrated structure. This significantly reduces the overall volume, thickness, and weight of the LED display screen, making installation more convenient and adaptable to various installation scenarios. It better meets the application requirements for lightweight and thin designs. The first LED display layer 200 is located outside the second transparent protective layer 130. The dark-colored solar cell layer 100 can serve as a natural background for the LED display screen, greatly improving daytime display contrast. It eliminates the need for high-brightness operation, saving energy and achieving energy self-sufficiency and efficient utilization. The first transparent protective layer 110, the second transparent protective layer 130, the first transparent lamp panel 210, and the transparent potting compound 500 outside the solar cell layer 120 are all designed with high transmittance, ensuring that the solar cell layer 100 is not blocked from light in any direction. This not only reduces the angle requirements during installation and improves installation convenience but also further guarantees photoelectric conversion efficiency. The first LED display layer 200 is encapsulated on the outside of the second transparent protective layer 130 using transparent potting compound 500. This not only avoids obstructing the sunlight received by the solar cell layer 100, but also improves interlayer adhesion and sealing, effectively preventing delamination, water ingress, and scratches, thus enhancing the device's weather resistance and lifespan. The display screen features a one-piece design, eliminating the need for complex on-site splicing and debugging. Custom sizes can be tailored to specific needs, allowing for direct on-site installation and significantly improving installation efficiency. The solar cell 120 can be paired with either rigid or flexible substrates, meeting both flat surface installation requirements and adapting to complex installation scenarios such as curved surfaces and irregular shapes, while maintaining low customization costs.

[0023] Example 2 Reference Figure 2Embodiment 2 of the present invention provides an LED display structure integrating solar cells. The difference between this structure and the LED display structure in Embodiment 1 is that the LED display structure in Embodiment 1 is a single-sided LED display structure, while in this embodiment, a second LED display layer 300 is encapsulated with transparent potting compound 500 on the outside of the first transparent protective layer 110, resulting in a double-sided LED display structure. The structure of the second LED display layer 300 is similar to that of the first LED display layer 200, including a second transparent light panel 310 and a second LED lamp 320, with the second LED lamp 320 soldered onto the second transparent light panel 310. The structure of the solar cell layer 100 is the same as in Embodiment 1 and will not be described in detail here. The second transparent light panel 310 can also be made of a high-transmittance flexible substrate as a flexible light panel. When the solar cell 120 is combined with the flexible substrate to form the flexible solar cell layer 100, the flexible light panel can be bent synchronously with the flexible solar cell layer 100, adapting to curved surfaces and irregular shapes, and the surface can be arranged with LED lamps according to a preset resolution.

[0026] Step S300, Layered Integration and Packaging: The first LED display layer 200 is laid on the outside of the second transparent protective layer 130 of the solar cell layer 100. The first LED display layer 200 is encapsulated with transparent potting compound 500. During encapsulation, the thickness of the potting compound is ≤3mm to ensure that the light transmittance of the encapsulation layer is ≥90%, thus forming a complete rigid single-sided LED display structure.
