The flexible transparent LED display film 100 mainly includes a film body 110, and the film body 110 is mainly used for carrying a circuit and a light emitting element.
The transparency of the film body 110 is 93-98%. In this embodiment, the transparency of the film body 110 is 93%, the transparency is good, the permeability is high, and the reduction of the user experience caused by the influence of light on the user is effectively avoided. Of course, in other embodiments, the film body 110 may have other transparencies, such as 95%, 96.7%, 98%, etc., and the user may select the film body 110 with a suitable transparency according to actual needs.
The film body 110 is made of a first flexible film, and the first flexible film can be a polyester film. The polyester film is a film material which is prepared by using polyethylene terephthalate as a raw material, preparing a thick sheet by adopting an extrusion method and performing biaxial tension. The rubber is a colorless transparent glossy film, has excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, friction resistance, high temperature resistance and low temperature resistance, and has good chemical resistance, oil resistance and air tightness. Which has good flexibility and bending properties as the membrane body 110. Of course, in other embodiments, the first flexible film may be other films as long as it has flexibility and bending property, such as polyimide film. The first flexible film is selected for use, so that the flexible transparent LED display film 100 has good transparency, and meanwhile, the flexible transparent LED display film 100 has certain bending deformation degree, can be attached to curved glass or a building for installation, and is suitable for installation scenes with various curved surfaces.
The bending curvature of the first flexible film is 1000R-1500R, in this embodiment, the bending curvature of the first flexible film is 1200R, so that the flexible transparent LED display film 100 can be integrally bent, and meanwhile, the light emitting angle and the visual effect can be effectively prevented from being affected after bending. Of course, in other embodiments, the first flexible film may also have other bending curvatures, such as 1000R, 1125R, 1500R, etc., and the user may set the bending curvature of the first flexible film according to actual needs during the use process, so that the user may perform cutting and splicing during the use process, and the size and shape of the first flexible film may be matched with various mounting areas or carriers, thereby improving the flexibility of the flexible transparent LED display film 100.
The film body 110 is printed with a metal circuit 112, and the metal circuit 112 is mainly used for conducting electricity. The width of the metal adopted by the metal circuit 112 is 10000nm-20000nm, the metal circuit 112 made of nano metal reduces the whole weight of the flexible transparent LED display film 100, and is convenient for a user to carry and disassemble, and meanwhile, because the visibility of the nano metal circuit is low, the sight of the user can not be obstructed by the metal circuit 112 when the flexible transparent LED display film 100 is used, so that the transparency of the flexible transparent LED display film 100 can not be influenced, and the experience of the user is improved.
The metal circuit 112 employs metal wires 114, and the metal wires 114 are distributed in a net shape on the membrane body 110. Fig. 1 shows one arrangement of the metal wires 114 on the film body 110, and referring to fig. 2, fig. 2 shows another arrangement of the metal wires 114 on the film body 110. In this embodiment, the metal wires 114 form a plurality of rectangular meshes on the membrane body 110, but in other embodiments, the meshes formed by the metal wires 114 on the membrane body 110 may have other shapes, such as rhombuses, triangles, parallelograms, and so on. The metal circuit 112 with the metal wires 114 distributed in a net shape at the nanometer level is adopted, so that light can penetrate through the net, the light transmittance can reach 93%, indoor light and the sight of a user can not be blocked, and the transparency of the flexible transparent LED display film 100 is improved.
The film body 110 is coated with a protective layer (not shown), which is mainly used for the dustproof, moisture-proof and oxidation-proof treatment of the metal circuit 112 and the light emitting diode. The protective layer can cover the surface of the film body 110 by spraying or soaking. The protective layer can adopt a nano coating with good light transmittance and smaller refractive index. Due to the arrangement of the protective layer, the ultraviolet resistance, the corrosion resistance and the weather resistance of the flexible transparent LED display film 100 are improved, and the flexible transparent LED display film has high impact resistance, so that the flexible transparent LED display film 100 is prevented from being damaged due to long-term contact with the external environment, the stability of indoor and outdoor application is guaranteed to the greatest extent, and the service life of the flexible transparent LED display film 100 is prolonged.
The flexible transparent LED display film 100 has a thickness of 0.5-1mm and a weight of 0.4-0.8kg/m2. In this embodiment, the flexible transparent LED display film 100 has a thickness of 1mm and a weight of 0.8kg/m2. The thickness is thin, the weight is light, and the transportation, the disassembly and the later maintenance of a user are convenient. Meanwhile, the pressure bearing of the installed carrier is small, so that the flexible transparent LED display film 100 can be suitable for more different installation scenes. Of course, in other embodiments, the flexible transparent LED display film 100 may have other thicknesses and weights, such as a thickness of 0.5nm and a weight of 0.4kg/m20.85nm in thickness and 0.55kg/m in weight2。
