Abstract | The invention provides a blue light prevention film, which comprises a silicon dioxide substrate, a metal nanoparticle structure, a graphene layer and a transparent protective layer. The invention also provides a display device, which comprises the blue light prevention film of the invention, an outer frame, a reflecting plate, a light-emitting diode, a diffusion plate, a diffusion sheet, a brightness enhancement film and a liquid crystal screen. The blue light prevention film can be arranged on the liquid crystal screen, between the brightness enhancement film and the liquid crystal screen orbetween the light emitting diode and the diffusion plate. Wherein metal nanoparticles are combined with a graphene layer structure in the blue light prevention film, and local plasmon resonance is generated when the metal nanoparticles in the graphene lay are excited by light, thereby enhancing the absorption of high-energy short waves by the graphene layer, and thus, the emission of high-energyshort-wave blue light that |
