Well, from the research I've looked at (specifically
the work done at Poloroid and their LIFT technology
and Motorola) the holographic light intensifyer is not
a film that is applied to the LCD. Instead, it is a
thin film that is inserted between the display and the
backlight. The film its self is transparent and is
only visible when tilted at an angle. This is similar
to those holographic images you can purchase for your
cell phone that shows some kind of 3-d picture on your
Cell Phone display;

Unfortunatly, I haven't been able to find any
distributor that sells them to an end user...
This is definatly something I would like to look into
and even implement on my Newt...if I can find someone
that sells it!
