First, thanks for all the great suggestions to a very tough problem.
Most of the time I can't see the rings, but in the right lighting they are there. I suspect that there are more cases of these, but people don't really notice them or don't follow up here.
And for the record, this is what I have so far:
The 2x00's LCD assembly has one glass piece, that is overlayed with 1 layer of a thin mylar film (the topmost layer) with a grid circuit in it. There "may" be another layer underneath this, that sits on the glass, with its own grid circuitry interacting with the mylar layer. Then, under the glass is the backlight. All of these "layers" are sandwiched together in an aluminum frame.
Newton's rings are common in photography. A couple theories arise. One, that there is oil underneath the top layer. Maybe I can fix that? Two, that there really is a second layer under the topmost mylar layer, and that is causing these Newton's rings since it has somehow come loose in those 2 areas. As such, when I put pressure on those areas, the Newton's rings expand. They are almost colored like as well. To me this would make more sense because the top layer is not in contact with any of the lower layers, and I can see the rings even without any pressure on the screen, which leads me to believe that it is something underneath the top layer that is causing this.
As such, the top layer probably just magnifies the rings in its own way, but is not the actual cause.
Sonny, or anyone else, can I buy a screen replacement from you?
Another question, if I replace the LCD, do I have to replace the
backlight? My backlight is strong and bright, so it does not need to
be replaced.
