I want to buy one, the theater is damaged, bad. Can be determined to use a polarizer, but it is not known whether the line is biased or round
In fact, I'm exaggerating. The roundness is only a little more expensive than the line. I give you simple to say, line partial glasses must face the screen, will have the ideal 3D effect, and round partial can achieve all-round 3D effect.
The cinema is definitely polarized glasses, is a simple linear polarizer, only the need to engage in the use of photographic circular polarizer
So you say Taobao, Jingdong said that it is round biased, that is because the circle is better, but in the end is not true, you have to rely on their own screening. As for what you should buy, it depends on your viewing effect and cost performance bias. If my answer to help you, please adopt.
