摘要:
Various embodiments related to a rear projection display screen configured to reduce an intensity of light at a viewing angle at which the light is less likely to be viewed by a user are disclosed. One disclosed embodiment provides a diffusing screen comprising a sheet-like structure transparent to one or more wavelengths of light.
