CrunchGear: "The technology associated with 3D content is getting better, and the dark screens and headaches plaguing the more sensitive viewers may soon be a thing of the past. Personally, I hope these expensive, complicated LCD shutter glasses go the way of the dodo, but until then, they may as well be as good as they can get.
These new Toshiba screens, made specifically for shutter glasses, have improved switchover time between open and shut, and block more light when shut to boot. It cuts down on 3D field “crosstalk,” in which your left eye sees partially the image meant to be seen by the right. Causes headaches and such."
