Losing 50% of the color-filtered light makes the display as dark as they are now (The pre-fix blue displays) which is probably not good either.

This comes back to "let's get a clear screen" and attach the material you're mentioning to it (or bond it, or however it works). Losing 50% of the unfiltered light from the display would probably be fine, IF there was significantly reduced glare (as you describe it there should be).

Rob? Do you have something perhaps I can tinker with?
