The sizes of the nano-scale photonic crystals in the technical scheme are not uniform, and the diameters of the nano-scale photonic crystals are within the range of 10-500 nm.
It should be noted that the nanoscale photonic crystal is a periodic structure formed by alternately arranging materials with different high and low refractive indexes, and the structure of the nanoscale photonic crystal can generate an optical band gap, and the optical band gap has a wavelength selection function and can selectively allow light in a certain wavelength band to pass through and prevent light in other wavelengths from passing through, so that the nanoscale photonic crystal has a dispersion characteristic.
The light with different wavelengths is incident on the nanometer level photon crystal with a certain angle, the refraction angles of the light with different wavelengths are different, and the nanometer level photon crystal can separate and weaken the light with different wavelengths. The projected image is subjected to dispersion and diffuse reflection among the nanometer-scale photonic crystals with different sizes, after the projected image is subjected to light reflection for multiple times, the color of the projected image can be uniformly diffused, harmful blue light in the projected image can be reduced, and therefore the light of the projected image picture is uniform.

Because the absorption rate of the single-layer graphene to visible light perpendicular to near-infrared light is 2.3%, the graphene layer can be subjected to multi-layer graphene arrangement in order to improve the absorption of harmful blue light by the graphene layer. Since the thickness of the single-layer graphene is only 0.335 nm (the diameter of one atom), 20 ten thousand layers of single-layer graphene are stacked together, and only one hair is thick, the multilayer graphene in the technical scheme is far less than 20 ten thousand layers, 5 to 100 layers can be selected in the embodiment, and the graphene also has the characteristic of transparency.

The projection layer 5 is arranged on the smooth surface of the AG glass.
In a more preferable technical scheme, the transparent substrate 3 can also be tempered glass, transparent PC, transparent acrylic plate or ordinary glass, and a light-resistant film is further disposed on a surface of the transparent substrate away from the photonic crystal coating. Note that, in this case, the material of the transparent substrate 3 is a transparent material suitable for a screen, and may be other than the above ones, and the embodiment is not limited thereto.
In this embodiment, the light-resistant film is adhered to the surface of the transparent substrate 3 away from the photonic crystal coating layer through the back adhesive layer.
