What is the difference between active and passive 3D TVs and which one is Cinema 3D TV?
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 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 pol…arized 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.
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.
There are two different 3D TV manufacturers that use different technologies. One is shutter glasses 3d technology which is used by Samsung, Sony, and Panasonic and the other o…ne is cinema 3d used by LG and Vizio. Active technologies deliver a full HD image in 3D mode whereas Lg's passive system cuts the resolution down to just 540 lines. LG's system is cheap compared to the premium brands so it's worth considering if you are on a tight budget.
Cinema 3D is LG's name for their 3D television. It doesn't make any difference with another television because it's only used by LG. It features half resolution images with …540 lines to each eye rather than full 1080 resolution. Standard definition reached 576 lines almost fifty years ago so 540 lines is disappointing to say the least. It has borrowed the technology from movie theater 3D system in use more than twenty years ago. It uses cheap glasses and you can use movie theater disposable glasses if you wish.
3D has been around for a long time. In fact, the first 3D television demonstration was by John Logie Baird in 1928. It has taken a long time for television technology to rea…ch the point where 3D is viable. Cinema 3D is the LG brand name for polarizing separation of two images. The technique has been in use for decades. LG and others have copied the technique from the film industry and applied it to television.
It is called Cinema 3D, a term that LG takes to name their latest technology in 3D TV. It is labeled as Cinema 3D because it is similar to the technology in the cinema, especi…ally the 3D glasses. They're battery free and do not contain any electrical devices making it significantly lighter to wear. With this kind of 3D glasses, you won't get any painful effect such as eyestrain and pain in your back ear.
Cinema 3D TV is the technology LG uses for their passive TV models. Their name comes from their TVs having similar technology to the 3D used in cinemas hence, "Cinema 3D TV". …This technology however is only available on LGs LW series and can be purchased at just about any retailer.
No, there's actually Vizio 3D TV called Vizio Theater 3D. They use the same technology as LG.
How the passive 3D TVs that have larger horizontal viewing angle different from active 3D TVs that have larger vertical viewing angle and which one is better?
All televisions are different so if you are choosing a new television, particularly a 3D model, check that the viewing angles in your own room will work with the television yo…u are considering. It's worth drawing a sketch of your room and measuring seating locations. Then you can simulate those positions in the store. It will take a few minutes but it's well worth it. If one model proves to have a limited viewing angle, move on to another and try again. AS well as checking for picture quality, this will help you make the choice will fit your home and family.
In theory, active 3D TVs are supposed to have better image quality than passive models. Passive televisions such as LG split the image lines so each eye sees only 540 lines…. With an active 3D image, each eye sees a full 1080 lines. For resolution, choose an active television. Before buying, do experience both active and passive models and make your own judgment. . For non-3D viewing, you must look at the technology used to make the display. Modern TV's use an LED backlight, and some have the capability of local dimming, that is, turning off backlight LED's for areas of the screen that are back. This can make a big difference in the contrast ratio of the screen, and is most noticable during movie titles. For 3D viewing, you should get a chance to view 3D Blu-Ray content (not a demo disc, but a movie) on the screen.
Is it true that passive 3d tvs are better than active 3d tvs and which one is the best passive 3d tv?
No it isn't. Passive television splits alternate lines to each eye so effectively they reduce the resolution to only 540 lines. That's even worse than standard definition of… 576 lines. LG make passive 3D televisions. They are one of the only manufacturers that make passive 3D televisions so by default they are perhaps the best. If you want to get a television with 3D resolution below even SD televisions, the LG is definitely the one to go for. Of course, you might want to look at the active 3D televisions made by almost every other manufacturer before you spend money on an LG.
Vizio models are cheap and perhaps not the best 3D quality available. However, they are good value for money and if you like the pictures they produce, they are worth buying.
Cinema 3D is the term LG uses for their 3D technology. This does not apply to all LG models. Only the passive 3D line in models that start with LW. Ex: LW6500, LW5600.

Because they aren't better than active 3D television. Both have their advantages. Passive televisions use polarizing glasses to separate the left and right eyes' images. The… effect is that the perceived resolution is cut in half to 540 lines, less than the 576 lines of older standard definition images.
Both are almost same except only for some few features related to content sharing and internet applications. A 3D TV(can also be a smart TV+3D) can view 3D content, whereas Sm…art TV has more internet applications. Smart TV comes with more applications like face book, YouTube, Skype, web browsing, Picasa etc. .
LG calls its 3D technology Cinema 3D so the 3D models all use that title.

Will the active 3D glasses work with passive 3D tv We have an LG passive 3D TV and we need extra ones My friend has an active 3D TV though so I was wondering if I can just borrow his 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 d…on'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.
