Abstract
The image quality of projection displays is decreased by ambient light. This paper proposed a screen that composed of a microlens array film with printed black ink stripes on back side and a matte‐white‐reflection film to reduce the influence of ambient light in the front projection system. The ambient light was guided to light absorptive black ink by micro‐lens and thus enhance the contract ratio of the image in the bright environment. A proposed screen performed a better than 6.5 times improvement in image contrast ratio without sacrificing viewing angle compared to a matte‐white screen under ambient light condition was demonstrated. The proposed projection screen works well in short‐to‐standard throw projectors and good for home or public applications.
