Projector and stereo image system

Abstract

The invention discloses a projector and stereo image system, which is applied in the projection technical field. The projector applies the polarizing filter to produce alternate image signal lights according to scheduled time such as 120 frames per minute, each image frame alternates in order, then a projection lens converts the polarized image signal lights into new polarized image signal lights with parallel vibration direction and constant polarization frequency, and the vibration direction of the mew polarized image signal lights does not change while the mew polarized image signal lights are reflected to the polarizing glasses through a projection screen, an observer can only observe corresponding image through a left lens, a right lens of the polarizing glasses, namely, the observer receives a left eye frame, then a right eye frame, another left eye frame and another right eye frame through the polarizing glasses, so that stereoscopic perception is produced in the visual nerve system, stereoscopic image appreciation is achieved, and stereoscopic image appreciation is achieved through one projector.

Description

technical field [0001] The invention relates to the technical field of projection, in particular to a projector and a stereoscopic image system. Background technique [0002] A projector is a device used to project image signal light onto a projection screen for imaging. Existing projectors include digital light processing (DLP) projectors, liquid crystal on silicon (LCOS) projectors, liquid crystal (LCD) Projector. [0003] See figure 1 , is a schematic diagram of an existing projector, and the projector 100 includes: [0004] an image signal processing device 101, configured to generate image signal light; [0005] The projection lens 102 is arranged on the transmission path of the image signal light generated by the image signal processing device 101, and is used for projecting the generated image signal light to a projection screen for imaging. [0006] See figure 2 , is a schematic diagram of an embodiment of an existing digital light processing projector, the dig...

Problems solved by technology

[0024] Stereoscopic projection is realized through the principle of light polarization. The existing scheme to realize stereoscopic projection is to use two projectors to project images synchronously, and make the polarization directions of the polarizers in front of the two projectors perpendicular to each other, so that the generated two The polarization directions of the polarized light beams are also perpendicular to each other, and the polarized light direction will not change when the polarized light is projected to the special projection screen and then reflected to the viewer's position. The viewer can only see the corresponding polarized light through the left and right eyes of the polarized glasses image, thereby generating a stereoscopic sensation in the visual nervous system to achieve the purpose of viewing stereoscopic images. The prior art cannot achieve the purpose of viewing stereoscopic images through a projector
