Why do 3D glasses have to go to the battery?
To install the eyes of the battery is relatively good 3D eyes, as if the battery is still possible, you can use 2 years look like it, this battery is not expensive to buy, the city has sold some!
Now the domestic 3D technology is not mature, are bragging, but you said to install the battery's eyes are good 3D eyes, as if the battery can still, you can use 2 years like this, this battery is not expensive to buy, sell the electronic city!Its principle is: when the display output of left eye image, the left eye lens to a transparent state, and the right to a non transparent state, and in the right eye image display output, right eye lens and eye transparent and opaque, so two glasses to see a different picture of the game, to achieve the purpose of deceiving eyes.
Of course battery...3D glasses are divided into two kinds, one is a long time ago, the kind of red and blue lens light, the advantage is cheap, a few dollars or even their own production can be, the drawback is that the effect is very poorThe other is a new, that is, the kind of battery, through the control of the power off to achieve light, the advantage is good, the disadvantage is that the price is more expensive
