Passive glasses are lighter, and a little cheaper than active glasses.
Passive glasses are under £10 whereas active glasses start at a little over $10.
Passive glasses need no batteries but the resolution of passive 3D such as LG is half that of other 3D systems at just 540 lines, lower than the standard definition of 576 lines that was introduced almost 50 years ago.
If you have passive 3D TV then yes you can watch Avatar 3D with its passive 3D glasses.
Active 3d glasses will not work with passive 3d TV. Active glasses use shutter 3D technology that requires a power source to power the lenses in the glasses. Passive glasses don't have electronics or batteries. Hence, they are lighter and more comfortable. Active and passive TV work using completely different technology and thus active glasses cannot work on passive TV.
Active 3D glasses are far better than passive glasses when used with an active 3D television. Similarly, passive 3D glasses work well with passive televisions. Active glasses have been criticized for their weight in the past. Later glasses are lighter than many passive glasses, have a battery life of over one hundred hours and are proving to be exceptionally reliable.
when you red and blue glasses
For any passive 3D television, the 3D glasses from movie theaters will work.
LG 3D TVs have the cheapest glasses. The passive 3D TVs that is. They require the use of polarized lens which will work on almost any passive 3D TV and the cinema as well.
Well, passive 3D glasses can solve your problem, but they'll only work on passive 3D TV. Passive glasses don't have use batteries or electric circuit. They are almost the same as normal polarized sunglasses. Truly, passive glasses are amazingly comfortable for the eyes.
Currently, all 3D televisions need glasses but the latest one are now only a few grams in weight. Active glasses are almost as light as passive glasses so there is no need to put up with the reduced resolution of LG passive 3D just to get light glasses.
No, there is no battery used in LG's 3D TV glasses as they have chosen to use passive glasses.
Battery powered 3D glasses means they are active 3D glasses and they only work with their own manufactured brand. However the compatibility of passive 3D glasses for other TVs are much higher. They work on any 3D TVs or theaters if they use the same passive technology. The passive 3D TV glasses are also lightweight due to no batteries being attatched. Plus, they don't need to be charged everytime before/after use unlike the active ones.
There are two technologies in use with 3D television. Active 3D requires glasses that have batteries while passive models do not. Crosstalk in active glasses has been a problem but it depends on the make of glasses and television. For passive 3D, look at Sony, Visio, Toshibe or LG.
Passive 3D TVs polarizing glasses similar to those at the movie theaters.
