Projection screen and projection system thereof

摘要

A projection screen includes a substrate having a projection area for a projection device to project an image onto the projection area. The projection area includes a plurality of arrayed optical regions, and each pixel of the image corresponding to the at least one optical region. Each of the optical regions includes a first optical sub-region and a second optical sub-region with different optical characteristics, such as reflective scattering, transmissive scattering, simple transmission or specular reflection. The above-mentioned projection screen with the optical characteristics of two or more, for example, can be at the same time as the front projection screen and the rear projection screen, or allows the user to watch background image behind the projection screen. A projection system including the above-mentioned projection screen is also disclosed.

1. A projection screen comprising:
a substrate having a projection area for a projection device to project an image onto the projection area, wherein the projection area comprises a plurality of arrayed optical regions, at least one optical region is corresponding to one pixel of the image projected on the projection area, and each of the optical regions comprises a first optical sub-region and a second optical sub-region, wherein the first optical sub-region has a first optical characteristic of reflective scattering, transmissive scattering, or specular reflection, the second optical sub-region has a second optical characteristic of simple transmission, and the area of the second optical sub-region is larger than that of the first optical sub-region.
