技術說明

一種投影螢幕包含一基材，其具有一投影區域，以供一投影裝置投射一影像至投影區域。投影區域包含多個陣列排列之光學區域，且影像之每一像素對應至少一光學區域。每一光學區域包含一第一光學子區域以及一第二光學子區域，其具有反射散射、透射散射、單純透射或鏡面反射等不同之光學特性。上述之投影螢幕具備兩種以上之光學特性，例如可同時作為前投影螢幕以及背投影螢幕，或者可讓使用者觀看投影螢幕後方之背景影像。同時亦揭露一種包含上述投影螢幕之投影系統。 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.
