( CNET ) -- Ceatec did n't officially start until Monday , but Toshiba was already getting the lion 's share of the buzz here on the show floor , with its glasses-less 3D TV . The device was announced Sunday night , and people flocked to the demonstration in a dark makeshift theater Monday , where the wait was nearly an hour . The reason ? Because finally , mercifully , a TV maker has come up with a way to watch 3D at home without those ridiculous plastic glasses . There were three sizes on display : 12 inches , 20 inches , and 56 inches . While the smaller size models are destined for the Japanese market in December , the 56-incher is just a prototype and there are no imminent plans to make it into an actual product , according to a Toshiba representative here . The 3D Regza TV uses the Cell Broadband Engine that takes a 2D image and then simultaneously creates nine images of it from nine different directions , in real time . It 's displayed on a high-definition LED TV . CNET : Watch an explanation video of how the technology works . After spending some time in the theater , we found the TV works surprisingly well . It 's not a 3D cinema-quality experience , and there 's clearly room to improve , but again , you do n't have to wear any glasses . Still images fare better than moving images . And you have to sit ( though we stood during the demo ) very close to the center of the screen to get the effect . With the 12-inch version , move more than a few inches to the left or right and the 3D effect is lost . However , the viewing angle was better on the 20-inch model , and the best on the 56-inch one . And there 's another matter of practicality : to get the best effect , you have to stand pretty close to the LED TV , closer than any normal person would want to for fear singeing their retinas . That 's why the glasses-less 3D laptop , a Toshiba Dynabook , is a far more realistic application of the glasses-less technology : It 's the same size as the 12-inch TV , but since it 's natural to sit very close to a laptop and look at it straight on , the aforementioned problems are negated . The 12-inch 3D TV goes on sale in Japan at the end of this year for 120,000 yen , or $ 1,500 . The 20-inch will have a 240,000 yen price tag , or about $ 2,900 . Sorry , rest of the world , you 'll have to wait , since there 's no timetable for bringing either to other markets . © 2010 CBS Interactive Inc. All rights reserved .
