| DukeOfLuxembourg said: Actually there are four different kinds of “formats”. Number 1 is kinda the cheapest form in which you wear a green/red glasses. These will often also be included if you buy 3D DVD’s at this moment. The 3D effect is made by displaying green lines and red lines on the screen which will be filtered by the corresponding color in the glasses. Number 2 is the one in cinema’s and the one that LG and other manufacturers use. In this case the 3D effect is made with using vertical and horizontal lines which are filterd by the glasses to the corresponding eye. Number 3 is the one SONY uses and requires active shutter glasses which have to sychronize with your TV. The 3D effect in this case is made by displaying one frame for the left eye and the next frame is for the right eye and so on…. (Thats why one of the Bravia’s is 400Hz (200Hz per eye)). Number 4 is not really used right now, because the technology is way from perfect. It requires no glasses, but you have to be exactly in front of your screen for it to work. The 3D effect is made by a mask over your screen, which will divert the light intended for the one eye to that specific eye. (That's why you have to sit in the center of the screen.) The problems with number 1 and 2 is that you have to have an extra bright picture to be able to get the 3D effect and the glasses (especially the polarized) will filter the normal light around you too, which is the main source of the headaches some people get from watching that. Numbers 3 and 4 have the complete light spectrum available without affecting the 3D effect, which gives you more colordepth and more contrast. Some of LG’s TV’s use passive (polarised) whereas other use active. Active is the ONLY way to get Full HD per eye. Either of which the TV will decode the PS3’s 3D imagery and output it how the TV likes (active or passive) |
Whoa Jimmy...a lot of the stuff here is half true.
1. red /green
2. polarized (passive shutter glasses) - there are 2 types of polarized methods. Liner and circular. Linear provides the best 3D. LG is doing a passive glasses display using circular method and are only TV company doing so, but they also have active shutter display.
3. Active shutters - within active shutter diplays you can have 6 methods of 3D.
Sidy by side, top and bottom, Interlaced, vertical stripe, checkerboard and frequency. All have their benefits but only frequency method can do 1080p (and needs hdmi 1.3 or 1.4). Every major manufacturer is making these and selling you shutter glasses for 200 bucks a pop.
4. face masks...tech isnt available for sale.
Both passive and active methods are able to display 1080p resolution to each eye and each has their own advantages. Passive TV displays can not do 1080p per eye but DLP projectors can...
TV companies are pushing active displays more as they are going to make most money with those. However nothing beats polarized theater setups. Currently the best quality home 3D can be achieved with linear passive method...using 2 DLP 1080p projectors. A dual projector rig at home is even brighter than the cinema and has virtually no ghosting. All of these new active shutter LCD/Plasma displays will have slight ghosting.
