Embodiment 1
[0027] Such as figure 1 As shown, the zinc oxide nanoparticles 2 are first prepared by the sol-gel method, and the size of the zinc oxide nanoparticles is 20 nm. Secondly, the zinc oxide nanoparticles were mixed in the polyethylene terephthalate (PET) material at a ratio of 3%, and the transparent film layer 1 of PET was prepared by the co-extrusion method on the co-extrusion casting extruder. After 72 hours of quiescence, the finished product is cut and the thickness of the transparent film layer is 0.01mm. Finally, using an inkjet printing method and using electronic ink, the slit grating layer 3 is prepared on the PET film layer. The width of the slit grating is , Where i is the pupil distance of the human eye; a is the pixel width of the display device, and the width between the bars and the bars is the same as the width of the bars.

Embodiment 2
[0035] Such as figure 1 As shown, first, zinc oxide nanoparticles 2 are prepared by an alkoxide hydrolysis method, and the size of the zinc oxide nanoparticles is 100 nm. Secondly, the zinc oxide nanoparticles were mixed with the polyethylene (PE) material in the proportion of 0.1%, and the transparent film layer 1 of PE was prepared by the co-extrusion molding method on the co-extrusion casting extruder. After 72 hours of static Then cut the finished product, the thickness of the transparent film layer is 2 mm. Finally, using an inkjet printing method and using electronic ink, the slit grating layer 3 is prepared on the PE film layer. The width of the slit grating is , Where i is the pupil distance of the human eye; a is the pixel width of the display device, and the width between the bars and the bars is the same as the width of the bars.
Embodiment 3
[0037] Such as figure 1 As shown, first, the zinc oxide nanoparticles 2 are prepared by a hydrothermal method, and the size of the zinc oxide nanoparticles is 1 nm. Secondly, the zinc oxide nanoparticles were mixed into polyethylene naphthalate (PEN) material at a ratio of 10%, and the transparent film layer 1 of PEN was prepared by the co-extrusion method on the co-extrusion casting extruder. After 72 hours of quiescence, the finished product is cut and the thickness of the transparent film layer is 5 mm. Finally, using an inkjet printing method and electronic ink, the slit grating layer 3 is prepared on the PEN film layer.
[0038] The width of the slit grating is , Where i is the pupil distance of the human eye; a is the pixel width of the display device, and the width between the bars and the bars is the same as the width of the bars.
