Polarizers with optical films

Abstract

The invention relates to a polaroid with optical thin-films. A boron-doped nano ceramic thin-film formed through chemical vapor deposition, a nano composite metal film formed through arc ion plating deposition and a nano composite oxide film formed through magnetron sputtered deposition are sequentially formed on a polaroid substrate. The polaroid with the optical thin-films has excellent light transmittance, high optical efficiency and uniformity in imaging, and ensures that the definitions of images in all positions are kept the same, so that a composite three-dimensional image is free from double images and high in contrast gradient, and accordingly, fatigue of eyes is remarkably relieved; and the surface of the polaroid not only has excellent heat resistance but also has favorable wearing resistance.

Description

technical field [0001] The invention relates to the field of optics, more specifically the invention relates to an optical film on a polarizer. Background technique [0002] The principle of existing polarized stereoscopic imaging is attached Figure 1-2 As shown, different image sequences of left and right frames are output from image output devices such as projectors and projectors. After passing through left and right circular polarizers, the left and right frames that make up the image are decomposed, and the left or right frame image is modulated and coded by a polarization modulator. , encoded into one of the following three-dimensional formats: (1) the left frame image becomes left-handed polarized light, and the right frame image becomes right-handed polarized light; (2) the left frame image becomes right-handed polarized light, and the right frame image becomes right-handed polarized light. The image becomes left-handed polarized light; by wearing the corresponding ...

Problems solved by technology

However, the polarizer used in the polarized stereoscopic imaging in the prior art is made of plastic material, and is dyed with a copper sulfate solution to form a polarizer. Its defects are: low light efficiency, easy to accumulate dust, easy to scratch, It consumes a lot of materials and the process is complex; thus directly causing the following disadvantages in the existing polarization stereoscopic imaging effect: a. Low imaging light efficiency, due to the characteristics of plastic materials, the overall light efficiency is relatively low; b. Imaging is uneven, The images seen by the left and right eyes have inconsistent clarity in different parts; c. There are double images in the imaging, the image contrast of the left and right eyes is poor, and the crosstalk is high; d. The life of the polarizer is low, due to the short distance between the polarizer and the projector, resulting in The heat of the light source on the projector is absorbed by the polarizer material, causing the polarizer to work at high temperature for a long time, and the polarizer material itself cannot withstand high temperature, resulting in a relatively short life
