Title: Projection screen
Inventor: GRAETZ MICHAEL L
IPC: H04N5/74
Filed: 2008-04-23
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.
