Embodiment 1

[0026] like figure 1 As shown, first, a certain amount of polyethylene terephthalate (PET) material, containing appropriate heat-resistant stabilizers, is co-extruded on a co-extrusion casting extruder, and passed through 72 hours of static Afterwards, the finished products are cut into pieces, and the thickness of the transparent film material layer 1 is 0.01mm. Secondly, titanium dioxide nanoparticles were prepared by a sol-gel method, and titanium dioxide nanoparticles 3 with a size of 10 nm were doped in the electronic ink at a ratio of 10%. Finally, the electronic ink is prepared on the PET transparent film layer by an inkjet printing method to form a uniformly arranged slit grating layer 2 .

Embodiment 2

[0035] like figure 1 As shown, first, a certain amount of polyethylene (PE) material, containing a suitable heat-resistant stabilizer, is co-extruded on a co-extrusion casting extruder, and then cut into pieces after 72 hours of static product, the thickness of the transparent film material layer 1 is 2mm. Secondly, titanium dioxide nanoparticles were prepared by thermal synthesis, and titanium dioxide nanoparticles 3 with a size of 60 nm were doped in the electronic ink at a ratio of 2%. Finally, the electronic ink is prepared on the PE transparent film material layer by a spraying method to form a uniformly arranged slit grating strip layer 2 .

Embodiment 3

[0037] like figure 1 As shown, first, a certain amount of polyethylene naphthalate (PEN) material, containing appropriate heat-resistant stabilizers, is co-extruded on a co-extrusion casting extruder, and passed through 72 hours of static Slitting into finished products is carried out again, and the thickness of the transparent film material layer 1 is 1mm. Secondly, titanium dioxide nanoparticles were prepared by alkoxide hydrolysis, and titanium dioxide nanoparticles 3 with a size of 100 nm were doped in the electronic ink at a ratio of 0.1%. Finally, the electronic ink is prepared on the PEN transparent film material layer by an inkjet printing method to form a uniformly arranged slit grating layer 2 .

Abstract

The invention relates to a novel 3D optical stereoscopic diaphragm and a production method thereof. The 3D optical stereoscopic diaphragm can be attached on a display screen of portable equipment, and ray of the screen is transmitted by the 3D optical stereoscopic diaphragm optically so as to realize 3D effect of naked eyes. The 3D optical stereoscopic diaphragm comprises a transparent film layer and a slit grating layer on the transparent film layer, wherein the slit grating layer is prepared by electronic ink doped with titanium oxide nano particles. Visual depth of 3D display is enhanced, flicker is reduced, 3D display effect is enhanced, and cost is reduced.

Description

technical field [0001] The invention relates to a novel 3D optical three-dimensional film and a preparation method thereof, belonging to the technical field of information display. Background technique [0002] At present, the 3D technology realized on global commercialized cinemas or television generally requires viewers to wear special 3D glasses. After wearing this kind of 3D glasses with black film, each eye can only get half of the light, and the brightness is greatly reduced, just like watching TV with sunglasses, and the glasses are easy to get tired. Simultaneously, the price of this kind of glasses is comparatively expensive, and operating cost is also higher. The current increasing technological development and people's ever-increasing requirements have promoted the emergence of naked-eye 3D. The biggest advantage of naked-eye 3D technology is that it does not require professional 3D glasses, and at the same time liberates the human eye, which is beneficial to hu...
