3-D TV is still experiencing some growing pains, in large part because of its reliance on bulky, uncomfortable and expensive active-shutter glasses. That's now changing. A new wave of 3-D sets are using lighter glasses to make immersing yourself in the third dimension less cumbersome. Eventually, believable 3-D won't require specs at all.
NOW: LIGHTER GLASSES
Instead of flickering the screen between left and right images, as is necessary with active glasses, LG's system puts both images onscreen at once. A filter polarizes each alternating horizontal line on the screen to match the polarization of pairs of passive glasses. The trade-off with this type of 3-D: Each eye receives only half of a high-def image—540 horizontal lines per frame, instead of 1,080.

SOON: LIGHTER GLASSES, BETTER PICTURE
RealD, a company that makes movie theaters 3-D, is developing a screen that will work with polarized glasses without halving resolution. While the TV flickers at 120 hertz between left and right images, a polarizing filter shifts with it, directing the light alternately toward either side, providing each eye with a full 1080p picture. The display will pop up in Samsung computer monitors next year and HDTVs soon after. RealD RDZ 3D Price not set
LATER: NO GLASSES AT ALL
Current glasses-free 3-D TV prototypes use a static, thinly striped LCD overlay to point images left and right, but such displays have limited viewing angles and can come out looking like cheap holograms. Researchers at the Massachusetts Institute of Technology's Media Lab have refined that technique, replacing the old pinstripe overlay with a matrix of thousands of tiny slits. A processor pre-scans the images to identify the subject of each frame. The system then configures the overlay to match the contours of the picture, so there's the illusion of depth only where it's needed. A Mini Cooper's roof, for example, gains a more pronounced curve.
Wow imagine the power of 3D TV without glasses. Now imagine it on regular television. I can watch all those paid programmings and commercials in stunning reality!

The paid programming is the 3D reality, OPE!
Vizoo already has some Tech. sorta like this in 3D holograms and I believe Samsung has non-glasses 3D TVs. With these Techs getting more advanced they will integrate each other together.
i just bought a vizio 42" 3dtv for less than 700$ after tax from walmart last week. i would just like to say to anyone thinking about getting one DO IT! i got my ps3 hooked up to it and it is sooooo sweet! Resistance 3 is especially impressive as is motorstorm and sonic generations!
