The choice in stores is huge. How to understand which of this variety is right for you? Let's take a look at the main parameters.
Consider the now popular 3D feature. 3D TVs smaller than 32 are simply pointless. The larger the diagonal, the better for 3D.
There are 2 types of 3D technologies: passive and active.
Passive 3D TVs are available from PHILIPS and LG. This technology uses polarized glasses. These are lightweight glasses without any equipment. They are versatile. With them, you can watch 3D movies on any TV that uses this technology, or you can go to the IMAX 3D cinema. In them, when viewing, you can calmly twist and tilt your head in any direction. But this technology also has disadvantages. Polarizing glasses work in the range from 2 to 6 meters (which, in principle, is imperceptible in an ordinary apartment). Well, the main disadvantage is the halving of the screen resolution.
Active technology means active 3D glasses. These are glasses with batteries or rechargeable batteries (sometimes with a cable to the TV). These glasses are expensive. Tilting the head can change the perception of the 3D signal. You don't go to the cinema with these glasses. Flickering may occur in dynamic scenes. But with all these shortcomings, the quality of 3D perception is still better than that of passive ones.
