Abstract

The invention discloses a projection display device, and the device comprises a projection light machine for emitting natural light; a polarizer which is disposed on an emergent light path of the projection light machine and is used for converting natural light into first polarized light and second polarized light, wherein the polarization directions of the first and second polarized light are perpendicular; a first projection system which receives the first polarized light and modulates the first polarized light to output a first projected image; a second projection system which receives thesecond polarized light and modulates the second polarized light to output a second projected image. The first projected image and the second projected image respectively have left eye or right eye image information. In the above mode, the device is capable of realizing 3D display.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a projection display device. Background technique [0002] Projectors have the advantages of small size, convenient movement, and wide projection range, and have been widely used in conferences and lectures. However, projectors in the prior art generally can only project 2D images. Contents of the invention [0003] The present application provides a projection display device, which can solve the problem that the projector in the prior art cannot realize 3D display. [0004] In order to solve the above technical problems, a technical solution adopted by the present application is to provide a projection display device, the projection display device includes: a projection light machine for emitting natural light; On the outgoing light path, it is used to convert the natural light into the first polarized light and the second polarized light whose propagation directio...
