When the light bounces off the screen to come back at you, the same happens, some of it goes through the screen protector, some of it bounces back to the screen. You can think of these reflections as ripples that affect the main light source, and degrade its quality. As long as there is something on top of the screen, there will be a drop off in sharpness/contrast.

I had hoped that current technology would prevent this to a degree. When the NGL first appeared in B&N stores I compared the NGL, NST and KT side by side. It was quite apparent that the NGL screen displayed less contrast/sharpness than the Simple Touch or Kindle Touch. If there is any degradation of the Perl display on the upcoming lighted Kindle I will be very disappointed.
