Looking for rigid RP screen solution

  • Hello,

    For a project that I am working on, we are looking for a solution for a rigid rear projection surface about 8' by 8' that can be inserted into a piece of scenery.  I've found a few solutions on the internet, including Screen Goo paint on projection surface, stick-on rolled projection surface (3M Vikuiti or similar), and pre-fabricated (expensive) RP screen panels.  I'm wondering if anyone has used any of these products before and could inform me how they perform relative to a normal stretched RP screen.

    Edit:  The Screen Goo or stick-on would be applied to Lexan or Plexiglass to make a solid screen.



  • Also, we have some offcuts of regular RP screen material, which I could just stretch and glue onto a piece of plexiglass, but I'm not sure what glue to use that would dry invisible and wouldn't disrupt the optics of the RP surface.

  • @craigalfredson I used a stick on film onto plexi, it was very hard to get a bubble free covering, but it looked fine. I did have the benefit of a longer viewing distance.

    I have made a couple of rigid rear projection screens using self-adhesive back projection film. Although I have used mostly the alternative product recommended in the report of tests at New York University of diffusion window tint films compared to optical screen films that found them to be comparable in image quality, brightness, viewing angle and hot spot reduction under optimal light conditions.

    The main reason is the reduction of cost which is significant when covering large street front windows for one off back projection projects. The product I use is Solyx window tint films, the SX-324 Frosted Sparkle.

    The image below (a popular glsl shader being projected) is a side window of a much larger window treatment to an historical building using the Frosted Sparkle film on all of the windows of the single story building. Unfortunately, we left the film in place for a couple of days too long and it ended up taking 4 people about 5 hours to remove it all with razor blades.

    I have made two of these great rigid back projection screens (below) using standard size 4mm acrylic sheeting and DIY'ing the application of the Frosted Sparkle film using lots of water with a couple of drops of detergent sprayed with an atomiser onto the sheet under the film so it can continue to be manipulated (and bubbles squeezed out) before sticking firmly to the sheeting. What's really nice about these is the projection is right to the edge (using Isadora's stage setup points) so the image appears to float. I intended to make 3 of them, but I attempted to apply the Frosted Sparkle by myself one day and it ended up a massive disaster - once the film gets stuck to itself or folds onto itself and gets stuck it is game over! The other 2 that were successful had 4 people assisting to ensure the film went down smoothly and in place. We used high density soft foam blocks to squeegee the bubbles out without leaving marks on the film.
