Active 3D TVs use shutter glasses to send images to the left and right eye one at a time very rapidly. This can also cause the viewer to see flickering. Passive 3D TVs use polarized cinema 3D Glasses which sends the 3D image to the eyes simulaneously, allowing viewers to view 3D exactly how we view objects in real life. The glasses for active type 3D TVs are around $100-200 while the cinema 3D glasses for passive TVs are about $10 each.

The main difference between active and passive 3D TVs is that active 3D TVs use shutter system and passive 3D TVs don't. Shutter system inserts a black frame after each image frame and the result is when your right eye is seeing an image, your left eye sees a black frame. Each side of the glasses take turn to project the image and the black frame i.e. the glasses. This causes flickering images and crosstalks. Passive 3D TVs, however, let your eyes see the 3D images as you naturally see other things. There are no black frames after each image frame. This allows the passive 3D TVs to be flicker free and crosstalk free. Cinema 3D TVs are passive 3D TVs. Passive TVs project images with more vibrant colors and of higher quality.
Active. Passive would be: Television is watched by the family to relax.
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.

Revealing how 3D TV glasses work, the difference between passive and active shutter glasses, plus new ... Easy to follow guide to the 3D TV technology used to deliver 3D imaging
3D TVs are a hot issue these days. Some say active 3D TV is better, some say passive 3D TV is better. I didn't see difference when I went to Best Buy.
LG only make passive 3D television. They do not supply any models that are active 3D.
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.
There are two types of 3D TV. One is the active type and the other is passive 3D TV. The first one is 'shutter glasses' and the second is 'polarized glasses'. Shutter glasses have a kind of shutter that needs a rechargeable battery. The active glasses last over 100 hours on a single charge these days and are as light as some passive glasses. Depending on the type of 3D television you have you will need one or other type of glasses.
First, you have to understand that there are two types of 3D technologies, active and passive. Active 3D TVs are like Panasonic, Sony, or Samsung's 3D TV. Passive ones are like Vizio or LG 3D TVs. Active 3D retains full HD resolution whereas passive cuts the effective resolution down to only 540 lines. However, passive is a cheap system compared to the premium brands.
FPR glasses are used by LG for their passive 3D television. They are used for the lower resolution (540 line effective resolution) passive system as opposed to the the premium brands of Sony, Panasonic and Samsung who all use active 3D technology to retain full HD resolution of 1080 lines.
