Abstract

The present invention discloses a stereoscopic display employing polarized eyewear. The basic component of the present invention stereoscopic display is a stereopolarizer, which is a polarized screen comprising microscopic sections of mutually extinguishing polarizing filters dispersed throughout the screen. To achieve the proper resolution, the size of the microscopic polarizing filter needs to be in order of micrometer, from a few microns to a few hundred of microns. The arrangement of the microscopic polarizing filters can be alternating stripes in horizontal, vertical, or any arbitrarily direction. The microscopic polarizing filters can be arranged in alternating pattern, such as alternating square or circle. The polarizer screen can be one sheet or can be a composite sheet, comprising two distinct polarizer filter sheet laminated together. Laser drilling is used to fabricate the microscopic polarizing filters, primarily due to ease of operation and appropriate microscopic sizes. Further, laser drilling and cutting can form angle holes in the stereopolarizer (91), which provides optimum focus viewing for horizontal perspective display.
