Abstract
The present disclosure reveals a reflective, front-projection screen designed to faithfully and accurately display the images from state-of-the-art (SOTA) and next-generation 2D and 3D motion-picture projectors, such as those found in large-capacity public movie theaters, home theaters, offices, and for use with portable projection systems for consumer and commercial applications. In particular it discloses cinema-size light shaping 3D projection screens with front-surface microstructures and horizontal viewing angles in the range of 90 to 120 degrees.
Claims11
A kit comprising:
- a plurality of screen sections, each screen section having a viewing side having a plurality of optical microstructures, a back side generally parallel to the viewing side, a seaming edge positioned between and transverse to the viewing side and the back side, and a beam on the back side that is disposed parallel to a respective seaming edge, the beam having a surface disposed generally transverse to the back side of the screen section and a cavity-forming portion that is configured to define a portion of a cavity in cooperation with the cavity forming portion of another screen section such that the cooperating cavity-forming portions sealingly surround the cavity;
- and
- a channel having an end portion configured to engage the generally transverse surfaces of a pair of the beams positioned adjacent and parallel to each other and main portion of the channel that narrows to a configuration that engages the pair of the beams with each other to sealingly surround the cavity.
A projection screen comprising:
- a plurality of adjacent projection screen sections, each projector screen section having a viewing side having a plurality of optical microstructures, a back side, and a seaming edge positioned between and transverse to the viewing side and the back side, with a pair of the screen sections being adjacent each other at the seaming edges of the respective screens spaced from each other by a seam having a width;
- a connector bridging the back sides of a pair of the screen sections at the seam between the screen sections and maintaining the seam width, each connector comprising a pair of the beam sections cooperating to sealingly surround a cavity;
- and
- resin in the cavity that binds the seam sections together.
