Embodiment 1

[0026] 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 a polyethylene terephthalate (PET) material at a ratio of 3%, and a PET transparent film layer 1 is prepared by co-extruding on a co-extrusion casting extruder, After 72 hours of stilling, the finished products are cut into pieces, and the thickness of the transparent film layer is 0.01mm. 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.

Abstract

The invention relates to a novel 3D (three dimensional) optical stereoscopic membrane and a preparation method thereof. The 3D optical stereoscopic membrane can be attached on a display screen of portable equipment, so that the naked 3D effect of light rays is realized through the optical transmission of the 3D optical stereoscopic membrane. The 3D optical stereoscopic membrane comprises a transparent membrane material layer and a slit grating layer on the transparent membrane material layer, wherein the transparent membrane material layer contains zinc oxide nanoparticles; and the slit grating layer is prepared from electronic ink. With the application of the zinc oxide nanoparticles, the transmittance of the transparent membrane material layer is increased, the viewpoint width of the 3D optical stereoscopic membrane is increased, and the double image degree is lowered. Therefore, 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...
