Projection screen

A method comprising:

• coupling a non-holographic, substantially flexible screen to a substantially transparent surface at a first position with a repositionable adhesive, wherein the screen comprises a rear surface for receiving light from a projector and a viewing surface opposite the rear surface;
• adjusting the screen relative to the substantially transparent surface from the first position to a second position without completely uncoupling the screen from the substantially parent surface;
• and
• securing the screen to the substantially transparent surface with the repositionable adhesive.

A projection screen for use in an optical system comprising a projector, the projection screen comprising:

• a substantially flexible light transmitting substrate;
• light absorbing means associated with the light transmitting substrate for controlling ambient light rejection so that the screen appears substantially dark in ambient lit conditions when no light is projected on the screen from the projector;
• and
• a repositionable adhesive configured to couple the screen to a substantially transparent surface in a first position so that viewers may view the screen through the substantially transparent surface, wherein the repositionable adhesive is further configured to permit a user to move the screen from the first position to a second position, relative to the substantially transparent surface without completely uncoupling the screen from the substantially transparent surface.

An optical system comprising:

• a projector for presenting an image;
• and
• a screen comprising a rear side for receiving light from the projector and a viewing side opposite the rear side, the screen being adapted to receive an image from the projector from the rear side of the screen and present it to a viewer from the viewing side of the screen, wherein the screen comprises:
• light absorbing means for absorbing ambient light;
• and
• a repositionable adhesive configured to couple the screen to the substantially transparent surface in a first position so that viewers may view the screen through the substantially transparent surface, wherein the repositionable adhesive is further configured to permit a user to move the screen from the first position to a second position relative to the substantially transparent surface without completely uncoupling screen from the substantially transparent surface.

A projection screen comprising:

• a first surface;
• a second surface opposite the first surface;
• an array of refractive elements, wherein the refractive elements are substantially surrounded by an opaque matrix and exhibit a refractive index in the range of 1.4 to 2.0, and wherein the opaque matrix defines an army of apertures;
• and
• a repositionable adhesive configured to couple the screen to an application surface in a first position, wherein the repositionable adhesive is further configured to permit a user to move the screen from the first position to a second position relative to the application surface without completely uncoupling screen from the application surface,
• wherein the screen exhibits a mechanical flexibility sufficient to allow it to be rolled up into a cylindrical roll having an inner diameter of 15.25 centimeters (6 inches) or less, and an attachment member associated with at least one of said first and said second sides of said screen.

A method comprising:

• selecting an application surface for application of a substantially flexible projection screen, wherein the projection screen comprises
• a substantially flexible light transmitting substrate;
• light absorbing means associated with the light transmitting substrate for controlling ambient light rejection so that the screen appears substantially dark in ambient lit conditions when no light is projected on the screen from the projector;
• a substantially flexible film comprising a stiffness greater than the substantially flexible light transmitting substrate;
• and
• an adhesive configured to couple the screen to the application surface;
• and
• coupling the projection screen to the application surface with the adhesive.
