Abstract

The invention discloses a projection system, comprising a projector, a first screen and a second screen, wherein the first screen comprises a plurality of first regions and a plurality of second regions; image light beams are projected to the first screen by the projector; the image light beams which penetrate through the first regions can penetrate through the second screen to enter into the right eye of an observer at a pre-set position, but cannot penetrate through the second screen to enter into the left eye of the observer; the image light beams which penetrate through the second regions can penetrate through the second screen to enter into the left eye of the observer, but cannot penetrate through the second screen to enter into the right eye of the observer. Therefore, the projection display of three-dimensional images is realized and the observer can see the three-dimensional images by naked eyes.

Description

technical field [0001] The invention relates to the technical field of projection, in particular to a projection system for stereoscopic display. Background technique [0002] In general, a projector has a function of easily enlarging the screen size according to its projection distance, and therefore, it is possible to easily realize image display on a large screen. The projector includes a front projector and a rear projector. The front projector projects and displays images on a reflective screen, while the rear projector projects and displays images on a transmissive screen. figure 1 A schematic diagram of an existing projection display system is disclosed. Such as figure 1 As shown, the projection display system includes a reflective screen 11 and a front projector 13 located in front of the reflective screen 11 . The projector 13 includes a light source, an imaging assembly, a filter assembly, and a projection lens, etc., wherein the filter assembly includes a plura...
