So there is a genuine generational difference between the SVGA pearl panels and the new XGA panels that goes beyond the frontlight/capacitance touch laminate.
Judging by how it works, I'm not sure if the pixel size can ever go below the thickness of the film (otherwise, I can't see the black/white gel being able to rotate over and back). So, finer pixels would mean a thinner layer of pigment, which would probably impact the contrast. I don't know how close the pixel size is to the film thickness, but I would suspect it's pretty close to it already.
