Stereoscopic display using polarized eyewear
First Claim
1. A stereoscopic display comprising a stereoscopic image, the stereoscopic image comprising a left image and a right image spatially multiplexed within the stereoscopic image;
- and a stereopolarizer screen comprising microscopic sections of a left polarizing filter and a right polarizing filter dispersed throughout the screen, the left polarizing filter and the right polarizing filter being mutually extinguishing polarizing filters;
wherein the stereopolarizer screen is adapted to synchronize with the stereoscopic image so that the pixels forming a left image match with the left polarizing filters and the pixels forming a right image match with the right polarizing filters, wherein a stereoscopic image is perceived with a corresponding polarized eyewear, the polarized eyewear allowing the left eye to see only the left image and the right eye to see only the right image, and wherein the stereoscopic display is adapted for display a stereoscopic horizontal perspective image.

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, which provides optimum focus viewing for horizontal perspective display.
