Description

Technical Field

[0001] This utility model belongs to the field of solar energy technology, specifically relating to a flexible double-sided solar display screen. Background Technology

[0002] Traditional LED displays rely on the power grid for power, resulting in high energy consumption and a significant carbon footprint. This is especially true in outdoor advertising and building facades, where installation costs are high, as are long-term operating costs.

[0003] In recent years, the maturity of flexible substrates such as polyimide (PI) or PET has enabled LED chips to be integrated on flexible and rollable transparent substrates, thus providing a certain technical foundation for this solution. At the same time, the lightweight and flexible development of photovoltaic technology (such as thin-film solar cells) has also made it possible for the display screen to be self-powered.

[0004] In recent years, with the increasing demand for lightweight, wind-resistant, and weather-resistant displays in scenarios such as the Internet of Things, wearable devices, automotive displays, and temporary exhibition halls, traditional rigid screens have been unable to meet these needs. The flexible double-sided LED display provided by this patent can fill the market demand and gaps. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a flexible double-sided solar display screen that is lightweight, thin, bend-resistant, long-lasting, and easy to install, addressing the shortcomings of existing technologies.

[0006] The specific technical solution is as follows:

[0007] A flexible double-sided solar LED display screen includes: a power generation and display section, an energy storage section, and an LED display screen driving section. The power generation and display section is used to convert solar energy into electrical energy. From top to bottom, it consists of a flexible front film layer, a front structural adhesive film layer, an LED display layer, a first back structural adhesive film layer, a solar cell layer, a second back structural adhesive film layer, and a back film layer, which are formed by lamination and sealing. The energy storage section is used to store electrical energy and supply power to the LED display layer through the display screen driving section.

[0008] Furthermore, the flexible front film layer and back film layer are fluorine-containing thin films with UV aging resistance.

[0009] Furthermore, the LED display layer is an LED display substrate with a transparent flexible substrate.

[0010] Furthermore, the front structural adhesive layer and the back structural adhesive layer are glass fiber resin mixtures that have high hardness and toughness after curing.

[0011] Furthermore, the power generation display section includes: a display communication terminal and a solar cell power output terminal.

[0012] Furthermore, the sunlight transmittance of the LED display layer is greater than or equal to 95%.

[0013] Furthermore, the solar cells in the solar cell layer are either double-sided solar cells or single-sided solar cells with the power generation side facing the LED light-emitting side of the display layer.

[0014] Furthermore, the solar cell types of the solar cell layer include: PERC, TOPCON, and HJT.

[0015] Beneficial effects:

[0016] This application provides a flexible double-sided solar display screen, which is lightweight, thin, bend-resistant, has a long lifespan, and is easy to install.

[0020] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0021] like Figure 1-3 As shown, a flexible double-sided solar LED display screen includes: a power generation and display section, an energy storage section, and an LED display screen driving section. The power generation and display section is used to convert solar energy into electrical energy. From top to bottom, it consists of a flexible front film layer 1, a front structural adhesive film layer 2, an LED display layer 3, a first back structural adhesive film layer 4, a solar cell layer 5, a second back structural adhesive film layer 6, and a back film layer 7, which are formed by lamination and sealing. The energy storage section is used to store electrical energy and supply power to the LED display layer through the display screen driving section.

[0022] Furthermore, the flexible front film layer and back film layer are fluorine-containing thin films with UV aging resistance.

[0023] Furthermore, the LED display layer is an LED display substrate with a transparent flexible substrate.

[0024] Furthermore, the front structural adhesive film layer, the first back structural adhesive film layer, and the second back structural adhesive film layer are glass fiber resin mixtures that have high hardness and toughness after curing.

[0025] Furthermore, the power generation display section includes: a display communication terminal and a solar cell power output terminal.

[0026] Furthermore, the sunlight transmittance of the LED display layer is greater than or equal to 95%.

[0027] Furthermore, the solar cells in the solar cell layer are either double-sided solar cells or single-sided solar cells with the power-generating side facing the LED-emitting side of the display layer. If the LED-emitting side of the display layer faces upwards, then the power-generating side of the single-sided solar cell also faces upwards.

[0028] Preferably, for single-sided solar cells, the solar cell layer faces the LED display surface on the LED display screen, and solar rays pass through the transparent part of the LED display screen substrate to illuminate the solar cell surface for operation. For double-sided solar cells, if the back is unobstructed during installation, the back can also generate electricity.

[0029] Furthermore, the solar cell types of the solar cell layer include: PERC, TOPCON, and HJT.

[0030] like Figure 2 As shown, the power generation and display section, from top to bottom, consists of a flexible front film layer 1, a front structural adhesive film layer 2, an LED display layer 3, a back structural adhesive film layer 4, a solar cell layer 5, a back adhesive film layer 6, and a back film layer 7. Each layer is stacked and encapsulated using a lamination process. This solution uses integrated lamination technology to encapsulate them together, giving it excellent anti-aging properties and allowing for long-term outdoor use.

[0031] Furthermore, the solar panel and LED display screen are encapsulated together with adhesive film and front and back films using lamination technology; and the front and back structural film layers not only have a sealing function, but also have excellent rigidity and flexibility, thereby protecting the solar panel, LED chip and flexible circuit from damage due to bending.

[0032] Furthermore, the front and back films are made of fluorinated membrane materials with excellent anti-aging properties, while also providing UV blocking functionality. Fluorinated membrane materials include PVDF (polyvinylidene fluoride), PVF (polyvinyl fluoride), and ETFE.

[0033] like Figure 3For the product's appearance layout, the LED display screen uses a transparent flexible substrate. The overall coverage of the LEDs and silkscreened wires is relatively low, thus ensuring good light transmittance on the front. The solar cells 104 of the solar cell layer are located below the LED display screen. 101 is the input terminal of the display screen driver, 102 is the power output terminal of the solar cell layer, and 103 is the LED light of the LED display layer. Since double-sided solar cells are used, both sides have power generation capabilities. Because the front LED display screen uses a transparent LED display screen, the power loss on the front side after encapsulation does not exceed 5%. The flexible solar double-sided LED display screen using this utility model has the characteristics of being lightweight, thin, bend-resistant, having a long lifespan, and easy to install, while protecting the internal materials such as the LED substrate from aging.

[0034] Beneficial effects:

[0035] This application provides a flexible double-sided solar display screen, which is lightweight, thin, bend-resistant, has a long lifespan, and is easy to install. It can solve the needs of IoT, wearable devices, vehicle displays, temporary exhibition halls, and other scenarios that require lightweight, wind-pressure-resistant, and weather-resistant displays.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
