Novel 3D optical stereoscopic diaphragm and production method thereof

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.
