Embodiment 1

[0029] Such as figure 1 As shown, the zinc oxide nanoparticles 2 were first prepared by the sol-gel method, and the size of the zinc oxide nanoparticles was 20 nm. Secondly, zinc oxide nanoparticles are mixed in the proportion of 4% and 1,8-diiodooctane additive in the proportion of 0.1% by weight in the polyethylene terephthalate (PET) material, which is used in co-extrusion casting The PET transparent film layer 1 was prepared by co-extrusion molding on an extruder, and then cut into finished products after 72 hours of resting. The thickness of the transparent film layer was 0.01 mm. Finally, the slit grating layer 3 is prepared on the PET film material layer by using an inkjet printing method and using electronic ink. The width of the slit grating is Wherein, i is the interpupillary distance of the human eye; a is the pixel width of the display device, and the width between the grid bars is the same as the grid bar width.

Embodiment 2

[0040] Such as figure 1As shown, zinc oxide nanoparticles 2 were first prepared by the alkoxide hydrolysis method, and the size of the zinc oxide nanoparticles was 100 nm. Secondly, the zinc oxide nanoparticles are mixed in the polyethylene (PE) material according to the weight ratio of 6.2% and the 1,8-diiodooctane additive according to the weight ratio of 3%, and co-extruded on the co-extrusion casting extruder Molding method The transparent film material layer 1 of PE is prepared, and then cut into finished products after 72 hours of stilling. The thickness of the transparent film material layer is 2 mm. Finally, the inkjet printing method is used to prepare the slit grating layer 3 on the PE film material layer using electronic ink. The width of the slit grating is Wherein, i is the interpupillary distance of the human eye; a is the pixel width of the display device, and the width between the grid bars is the same as the grid bar width.

Embodiment 3

[0042] Such as figure 1 As shown, first, zinc oxide nanoparticles 2 were prepared by a hydrothermal method, and the size of the zinc oxide nanoparticles was 1 nm. Secondly, the zinc oxide nanoparticles are mixed in the proportion of 4.5% by weight, and the 1,8-diiodooctane additive is mixed in the polyethylene naphthalate (PEN) material in the proportion of 2%. The transparent film layer 1 of PEN was prepared by co-extrusion on an extruder, and then cut into finished products after 72 hours of stilling. The thickness of the transparent film layer was 5mm. Finally, an inkjet printing method is used to prepare a slit grating layer 3 on the PEN film material layer using electronic ink. The width of the slit grating is Wherein, i is the interpupillary distance of the human eye; a is the pixel width of the display device, and the width between the grid bars is the same as the grid bar width.

Abstract

The invention relates to a novel 3D (three-dimensional) optical diaphragm and a preparation method. The 3D optical diaphragm can be attached to a portable equipment display screen; screen ray is subjected to the optical transmission of the 3D optical diaphragm to realize the naked eye 3D effect; the 3D optical diaphragm comprises a transparent diaphragm material layer and a slit grating layer on the transparent diaphragm material layer, wherein the transparent diaphragm material layer comprises zinc oxide nano-particles and 1,8-diiodooctane additive; the slit grating layer is prepared from electronic ink; the transmittance of the transparent diaphragm material layer is increased by the zinc oxide nano-particles; the viewpoint width of the 3D optical diaphragm is improved; the double image degree is lowered; the dispersibility and the evenness of the zinc oxide nano-particles are improved by the 1,8-diiodooctane additive; and finally, the 3D display effect is enhanced.

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...
