Toshiba Reveals Polarizing Filter 3D TVs
These sets are the first from the company to use polarizing filters to display 3D images; in this setup, "images for the right and left eyes are displayed on an LCD panel equipped with a polarizing filter, and the images are viewed with polarized glasses." Currently, only LG is also making a bit deal about this method. In general, these types of 3D TVs can emit images that are brighter and have less flickering, and the weight of the glasses is also reduced.
The only real downside is that the pixel counts of 3D TVs using a polarizing filter decrease by half in the vertical direction, but with screen sizes that small, Toshiba doesn't seem to think this will cause too much issue in real-world experiences.
