From what I understand, PDA LCDs have 3 layers.
1st layer, thin plastic coating. The stuff your stylus touches, that "pulls" the sides and tells the PDA where you're tapping. This is also the part you put that screen protector on to protect.
2nd layer. Glass/Rigid plastic. Ever wonder why when you tap hard on your screen that the display doesn't go "swimmy" like the LCD monitors on laptops or desktops? This is why.
3rd layer. The actual LCD, which is probably the most expensive party. This is the part that has that "ink" in it. When your iPaq sends electricity through the liquid crystal (the "ink"), it lights up. It's probably more advanced than this with those fancy transflective displays, but I'm not picking for details.
Looks like the 3rd layer, the deepest one in, got damaged somehow. Could it have been differences in temperature? I've seen weirder things happen.
