Transform your favourite films and sporting action – 3D TV makes you feel part of the drama. Featuring Passive 3D technology that allows for hours of comfortable 3D TV viewing for the whole family. The 3D glasses are lightweight too – so you’ll hardly notice you’ve got them on. The price of good passive 3D TV has fallen while the quality has improved considerably.

Advantages of Passive Polarized 3D TV glasses:
1. Lightweight
2. Inexpensive - About one quarter the price of Active Shutter glasses. The LG comes with 4 to 8 free glasses.
3. No flickering - which means less discomfort and eye fatigue over long view periods.

Overall, LG has the best passive 3D TV technology today and the prices have come down considerably.

As far as comfort and overall ease of use is concerned, passive 3D TV is a great choice.It's a good choice for the family because it provides hours of family fun and the 3d glasses are relatively cheap to replace if broken.

 Based on picture quality, reliability and excellent customer support, i'm going with LG 3D TV. To the right are the prices of this month's best models, it's the right time to pick one up.

Active 3DTV

So what is the difference between active and passive 3D TV?

 Passive 3DTV glasses are generally the 3DTV eyewear you see at movie theaters with polarized screens and plastic housings. Using filters to split the image, passive glasses are capable of receiving 1080p video, with one problem.

Your eyes receive a total of 1080p, meaning that only 540 lines are delivered to each eye, thus bringing the image quality below what is HD (and 720p of that) and very close to SD comprising of  480i. With a filter in place, you will also notice a reduced image brightness and clarity. On the other hand, active 3DTV glasses are capable of and do deliver 1080p to each eye, thus doubling the resolution. With the lack of filter in place as well, your video is brighter and much more crisp.

Active 3DTV glasses contain LCD lenses that alternately ‘block out’ each eye depending on whether the left or right image is being displayed on the screen. They are referred to as active because they require a battery to operate the LCD lenses. The shuttering occurs so rapidly that you don’t see the shutters just the amazing 3DTV picture.

As far as resolution is concerned, active 3DTV  produces full 1080p hd quality pictures, so this would be the way to go if you're a purist or enthusiast.
