Sharp announced their newest invention Saturday. It's a prototype 10" LCD screen that can create a 3D effect without glasses. Not that I said prototype; it's not in production yet. Details are sparse; all we know at this point is that it has a touchscreen and that you can switch between 2D and 3D at the touch of a button.
Supposedly this new screen is being touted for e-reading; I don't see how that would be useful. Video, certainly, but I think the 3D effect would get in the way of reading.
