Recently I've been pondering about a variation of the Light Fusion which uses phosphors to generate a true back-lit effect for brighter whites. This idea borrows from the old CRT systems where the electron gun hits the phosphor coated screens to cause a glowing image.
For the paint selection I believe one of the neutral grays would be best. We want something that will produce deep blacks, even at the expense of darker whites because the whites will be re-brightened with the phosphors. I don't think we will have to worry about the phosphors washing out the blacks because only the brightest pixels on the screen should be able to penetrate beyond the first layer of paint and reach the phosphor layer. The mirror would be used to reflect back any remaining light that made it to the last layer and also to direct the light emitted from the phosphors back to the screen.
The layer order:
Projector ---> black enhancing paint | phosphor paint | mirror
The cost of phosphor paint or phosphor powder to make your own paint is relatively low. If you decide to go this route you will want phosphor that glows white at the 6400k color temperature (similar to the phosphors that coat fluorescent lamps) and not the cheaper green glowing stuff.
Let me know what you guys think. I'm specifically looking for reasons why this idea wouldn't work, but improvements are also welcome. I won't be able to experiment for a while since I don't have a projector yet. Eventually I'll get to try this one out.
