3D TV technology in the duel: Polarization versus Shutter

Open both eyes when buying 3D

3D TV is not equal to 3D TV, is not the same - namely, the TV manufacturers are putting on two different techniques for spatial imaging: polarization and shutters. We show you the advantages and disadvantages of the two competing technologies and recommend the best 3D-TV.
Home theater in the third dimension - that is really great. However, you should consider before purchasing, to which of the two currently competing 3D techniques set want: polarization or Shutter?

More TV models with polarization
At IFA 2011 brings even more TV manufacturers 3D models using polarization technique on the market - for LG Electronics have now also Philips, Toshiba and Metz television with the passive glasses on sale. The TV market leader Samsung is however still only at shutter technique and also uses in its competitor Panasonic plasma TVs only 3D, this 3D version.

We help you understand, what are the advantages and disadvantages of Shutter and polarization technique and give you to each specific purchase recommendations: Top TV with shutter glasses and great TVs with 3D polarization.

The 3D image loses much brightness in polarization technology and annoying error in the form of double contours (crosstalk, ghosting) can be observed in TVs of this type do not or only very weakly. Only in the horizontal, the 3D image is not stable to vision - when you get up, you see the picture blurry or double. For this, the pole-glasses are relatively light and therefore comfortable to wear. In addition, they are cheap - a copy costs about 10 euros and TV manufacturers put in usually four of them.

Shutter technique

Shutter technique
The 3D shutter television shows, in contrast to the polarization TV always turns the image to the right and left eye and right eye shutter opens to the respective corresponding analog "glass". The biggest advantage of this technique: the dissolution of the film remains intact - he is in full HD with 1920 x represented 1080th

Pol-glasses: passive, easily and cheaply.

Crosstalk: If also through the double contours.
For this image in the form of double contours dive at the shutter technology more often - called also crosstalk, ghosting, or multiple images. These resulting from the fact that the display displays the correct image not fully synchronized with the shutter glasses,, or the previous image does not a moment too long or to glow. This means that, for example, the right eye for a very brief moment will see the picture for the left and vice versa - so appears double contours.

All manufacturers are trying to resolve this problem by always faster panels, LCD TVs on the market, that display 800 pictures per second - so we have also seen a reduction of cross talks for all TV producers over the last two years in our tests today.

Expensive shutter glasses
Relatively high image brightness is lost through the shutter glasses. Range and carrying position of the glasses are also somewhat problematic. So it happens that the glasses off, if you keep your head tilted or when you step out of the transmission range of the 3D channel. In addition, maximum of two shutter glasses are supplied with a 3D-TVs, many manufacturers set at none. Since then about 50 to 100 euros per copy will be extra charged.
