Abstract
A large format tiled flexible projection display screen. The tiled modules of the screen each include a rear projection screen film adhered to a transmissive flexible substrate with an optically clear adhesive. When electronic content is projected onto the tiled projection screens, the electronic content is visible on a front surface side of the substrates.
Claims23
A large format tiled projection display screen, comprising:
- a first module, comprising:
- a first projection screen film;
- a first transmissive flexible substrate having a front surface side and
- an optically clear adhesive between the first projection screen film and the first substrate;
