Toshiba is introducing a whole new lineup of LCD TVs, primarily with LED backlighting. The top of the line UL610 models (46-, 55-, and 65-inchesthe 55-incher is shown on the left in the photo). The UL610s use active 3D glasses for full HD 3D, claimed deep blacks (thought all of the Toshiba LED sets use LED edge lighting, not full backlighting), 480Hz operation, and special 3D crosstalk cancellation technology. All of the 3D sets in the ranges below the UL610 employ passive glasses technology.
I finally was able to see Toshiba's autostereoscopic 3D demos. They had some of the same problems described in the Sony's glasses-free 3D demo. I also noted a pervasive graininess in the images. This was visible in the Sony as well but I did not attribute it to the glasses free technique. It apparently is. Nevertheless, Toshiba claims that they will have these sets on the market late this year. As it stands now, however, 3D with glasses is still superior, apart from its lower brightness.
