  • PROJECTION SCREEN
    Publication number: 20100245995
    Abstract: A projection screen for use in a projection system that includes an image source, such as a projector, is substantially flexible. In one embodiment, the projection screen includes a film to provide stiffness to the projection screen. In some embodiments, the film may be substantially self-supporting, thereby allowing for easier manipulating of the projection screen, such as when the projection screen is coupled to an application surface. In other embodiments, the projection screen includes a repositionable adhesive. The repositionable adhesive aids the coupling of the projection screen to a desired position on the application surface. For example, a user may couple the projection screen to the application surface in a first position, and, while the projection screen is still coupled to the application surface, adjust the position of the projection screen to a second position, such as by sliding the projection screen between the first and second positions.

  • Rear projection screen with reduced speckle
    Patent number: 6466368
    Abstract: A rear projection screen has one or more internal layers that reduce the speckle perceived by a viewer. A screen assembly has a light-source side and a viewing side. The assembly includes a screen layer to disperse light passing through the screen from the light source side and a matte surface disposed on the viewing side of the screen assembly to reduce ambient glare. A first speckle contrast reducing layer is disposed between the screen layer and the matte surface to reduce speckle formed at the matte surface.
