The projection curtain comprises a bottom layer 1, a middle layer 2 and a surface layer 3 which are sequentially compounded.
The bottom layer 1 is a shading structure located on the back, specifically, the bottom layer 1 is made of PET (polyethylene terephthalate) serving as a base material and is fully coated with a black glue coating to serve as the shading structure, and the shading structure is used for enabling the curtain to be transparent on the back side when the curtain is watched on the front side, so that the influence of back side ambient light on the projection effect is reduced.
Referring to fig. 2, the middle layer 2 has a black-grating light-resisting structure, the middle layer 2 is made of PET as a base material, the front end of the middle layer is in a continuous sawtooth structure with a vertical linear vertical section, the lower inclined surface of the sawtooth structure is a light reflecting surface 21, the upper inclined surface of the sawtooth structure is a light absorbing surface 22, the light reflecting surface 21 and the light absorbing surface 22 are transverse surfaces, which are in the prior art, and the specific structure and the working principle according to the structure in the operation process are not repeated here.
In the implementation process, when the projection light incoming a emitted from the projector below the front face is reflected on the light reflecting surface 21, the reflected light outgoing b facing horizontally outwards is obtained, which helps to improve the projection effect.
Further, the light absorbing surface 22 is formed with a rough surface by a plurality of fine particle-like protrusions, and is doped with a dye ink, which helps to enhance the light absorbing capability of the light absorbing surface 22 for top light.
Further, referring to fig. 3, the surface layer 3 is a light-transmitting structure located at the front side of the middle layer 2, in this embodiment, the middle layer 2 is made of transparent PET as a base material, and a plurality of sheet curtain members 31 distributed at intervals laterally and laterally are disposed inside the surface layer 3, the sheet curtain members 31 are vertical sheet-shaped light-shielding members, and the light-shielding sheet material of the sheet curtain members 31 is a sheet-shaped structure formed by doping dyeing ink inside the surface layer 3. The sheet curtain 31 has a linear structure on the front surface, so that the front surface look and feel is not interfered excessively, but the sheet curtain 31 has a planar shielding structure on the left and right sides, and the shielding effect can be achieved when light on the left and right sides enters and penetrates the surface layer 3, so that the sheet curtain 31 can be used for shielding or absorbing the side light entering c on the left and right sides, and the bleaching phenomenon of the curtain caused by the side light entering c on the left and right sides is avoided, so that the projection effect is reduced. The rear end face of the surface layer 3 has a serration 33, and the serration 33 and the front end face of the middle layer 2 have complementary structures, so that when the serration 33 and the front end face of the middle layer 2 are combined, the rear end face of the surface layer 3 and the front end face of the middle layer 2 are in seamless fit, which helps to reduce refractive angle deviation generated when light enters.
