Assuming the scanning relies on illumination coming from the corresponding pixel, I wonder whether this works at all when the user is touching an unlit (black) region of the screen? Or is it the case that all pixels on this screen emit some light 100% of the time, even if they"re supposed to be "black" -- in which case, I wonder whether contrast isn"t being compromised for "image clarity"...

Now, all we have to do is develop a nano coating that will eliminate fingerprints and dust on the screen. One thing I highly object to in touch screen technology is the constant cleaning of fingerprints from the screen, which build up fairly fast. I've seen nanotech coatings that are totally resistant to such contamination due to thier unique texture. This could also be part of a nano solution to glare if the right combination of textures is applied to the screen surface.

I already have a need for this technology in several applications. I dont really
care about fingerprints and dust on the display, I am sure it can work just as well.

All pixels on all lcd screens always emit some light 100% of the time. Black is never true black and in fact that IS and has always been a problem on LCD monitors. That being said, assuming your assumption of the sensor using the pixels light to be correct, it would have no negative effect as they are turning an already existing problem into a helpful advantage.
