Problems solved by technology

[0004] However, in the existing stereoscopic projection system 10, it is necessary to use two projectors 11, 12 to generate projection rays L1, L2 with different polarization vectors. It can be seen from this that sufficient usable space must be provided to accommodate the two projectors 11 , 12, this kind of stereoscopic projection system 10 is easy to waste the use of space, coupled with the need to purchase two projectors, it will also cause an increase in cost, which really needs to be improved

Abstract

The utility model relates to a stereo projection system and polarizing color wheel. The polarizing color wheel comprises a glass body, a polarizing layer and a filtering layer, the polarizing layer is arranged at the glass body, the filtering layer is arranged at the glass body. The stereo projection system comprises a light source which emits light line; a filtering color wheel which is adjacently arranged at the light source, the light line passes through the filtering color wheel; a polarizing color wheel which is adjacently arranged at the filtering color wheel, the light line passes through the polarizing color wheel; and a screen which is adjacently arranged at the polarizing color wheel, the light line passes through the filtering color wheel and the polarizing color wheel, and is imaged on the screen. The utility model has the advantages of cost and space saving.

Description

technical field [0001] The invention relates to a stereoscopic projection system, in particular to a stereoscopic projection system with a polarizing color wheel. Background technique [0002] Please refer to FIG. 1 , which is a conventional three-dimensional projection system 10 , including a first projector 11 , a second projector 12 and a screen 13 . Wherein, the first projector 11 and the second projector 12 are arranged on one side of the screen 13, and the first projector 11 can emit a first projection light L1 to form an image on the screen 13, and the second projector 12 A second projection light L2 can be emitted to form an image on the screen 13 . The first projected light L1 shown in FIG. 1 is a P-polarized light, and the second projected light L2 is an S-polarized light. [0003] When the user wants to watch the stereoscopic image on the screen 13, the user must wear a pair of polarized glasses G. The polarized glasses G are respectively provided with a first p...
