Problems solved by technology

The metal screen only has a reflection effect. After the projected polarized light incident on the metal screen is reflected by the metal screen, the polarization characteristics change to varying degrees, which no longer meets the imaging requirements of 3D glasses and reduces the 3D imaging effect.

Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] In the following specific embodiments of the present invention, please refer to Figure 1 ~ Figure 3 . As shown in the figure, a projection screen includes a polarizing film layer 110. The polarizing film layer 110 includes a first polarizing module 112 and a second polarizing module 114. The first polarizing modules 112 and the second polarizing modules 114 are alternately distributed. The module 112 has a first polarization pattern emitting the first pola...

Abstract

The embodiment of the invention discloses a projection curtain and a projection system. The projection curtain comprises a polarizing film layer, which comprises first polarizing modules and second polarizing modules, wherein the first polarization modules and the second polarization modules are alternately distributed, each first polarization module is provided with a first polarization pattern for emitting first polarized light, each second polarization module is provided with a second polarization pattern for emitting second polarized light, and the direction of each first polarization pattern is different from that of each second polarization pattern. By adding the polarizing film layer, it is ensured that the polarization characteristic of the projected polarized light is not changedafter being reflected by the projection curtain, and the 3D imaging effect is improved.

Description

technical field [0001] The present invention relates to the technical field of projection, and more particularly, to a projection screen and a projection system. Background technique [0002] With the continuous development of 3D technology, 3D projection technology is also constantly developing. How to restore the image output by the projector to the greatest extent so that the audience can get the best visual effect is not only to improve the performance of the projector, but also the structure of the 3D projection screen plays a very important role, so the 3D projection screen The development of structures is also a trend. [0003] In the prior art, a metal screen is commonly used as the choice of a 3D projection screen, and a three-dimensional effect is formed by wearing 3D glasses. The metal screen uses the reflective properties of metals such as aluminum and silver to reflect back the projected polarized light emitted by the projector. The reflected polarized light i...
