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.

Thanks I hadn't researched how they were going to pull off the lighting. I was hoping they had a method that did not require a substrate. I definitely will not get one if they will use a substrate because as you said a substrate equals less contrast which equals a step backwards in quality. Most of the touchscreen readers that used an additional substrate sucked, and the rest were marginal at best. I know as I owned several Sony x00 and x50 models. The x00 sucked and the x50 were only marginal. Once they figured out a way to have touchscreen technology without an additional substrate they became readable.
