Problems solved by technology

[0004] In order to overcome the problem that the light output and brightness are halved due to the use of opaque gratings in the barrier-type naked-eye 3D technology, resulting in a smaller viewing point width and a larger ghosting degree of 3D display, the present invention provides a 3D optical stereo film and preparation method

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.

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.

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 3D optical three-dimensional film and a preparation method thereof, and belongs to the technical field of information display. Background technique [0002] Currently, the 3D technology implemented in global commercial cinemas or televisions generally requires viewers to wear special 3D glasses. After wearing this kind of 3D glasses with black film, each eye can actually only get half of the light, and the brightness is greatly reduced, just like watching TV with sunglasses, and the glasses are easy to fatigue. At the same time, the price of such glasses is relatively expensive, and the operating cost is also relatively high. The current increasing technological development and people's ever-increasing requirements have promoted the production of naked eye 3D. The biggest advantage of naked-eye 3D technology is that it does not require professional 3D stereo glasses, and at the same time it liberates human eyes and is beneficial...
