Friends , As per my understanding there are 2 to 3 types of 3d viewing are Commonly used to watch 3D Movies.
Stereoscopic effect used in Macro photography.

2. Polarized Goggles
A polarized 3D system uses polarization glasses to create the illusion of three-dimensional images by restricting the light that reaches each eye, an example of stereoscopy.
Compared to anaglyph images, the use of polarized 3D glasses produces a full-color image that is considerably more comfortable to watch and is not subject to binocular rivalry. However, it requires a significant increase in expense: even the low cost polarized glasses typically cost 50% more than comparable red-cyan filters.
Until 2011, home 3D television and home 3D computer primarily used active shutter glasses with LCD or plasma displays. TV manufacturers (LG, Vizio) have introduced displays with horizontal polarizing stripes overlaying the screen. The stripes alternate polarization with each line. This permits using relatively inexpensive passive viewing glasses, similar to those for movies. The principal disadvantage is that each polarization can display only half as many scanning lines.
This are the Four Switches on the Back of Led
An active shutter 3D system (a.k.a. alternate frame sequencing, alternate image, AI, alternating field, field sequential or eclipse method) is a technique of displaying stereoscopic 3D images. It works by only presenting the image intended for the left eye while blocking the right eye's view, then presenting the right-eye image while blocking the left eye, and repeating this so rapidly that the interruptions do not interfere with the perceived fusion of the two images into a single 3D image.
Unlike in a Polarized 3D system, where the screen resolution is halved when the images are combined, the active shutter system retains full resolution by combining the images over time.
Flicker can be noticed except at very high refresh rates, as each eye
is effectively receiving only half of the monitor's actual refresh
rate. However, modern LC glasses generally work in higher refresh rates
and eliminate this problem for most people.
Until recently, the method only worked with CRT monitors; some modern flat-panel monitors now support high-enough refresh rates to work with some LC shutter systems. Many projectors, especially DLP-based ones, support 3D out of the box.
LC shutter glasses are shutting out light half of the time; moreover, they are slightly dark even when letting light through, because they are polarized. This gives an effect similar to watching TV with sunglasses on, which causes a darker picture to be perceived by the viewer. However, this effect can produce a higher perceived display contrast when paired with LCD displays because of the reduction in backlight bleed. Since the glasses also darken the background, contrast is enhanced when using a brighter image.
When used with LCD displays, extreme localized differences between the image to be displayed in one eye and the other may lead to crosstalk, due to LCD panels' pixels sometimes being unable to fully switch, for example from black to white, in the time that separates the left eye's image from the right one. Recent advancements in the panel's response time, however, has led to displays that rival or even surpass passive 3D systems.
Frame rate has to be double that of a non-3D, anaglyph, or polarized 3D systems to get an equivalent result. All equipment in the chain has to be able to process frames at double rate; in essence this doubles the hardware requirements.
Despite a progressive fall in prices, and due to the intrinsic use of electronics, they remain more expensive than anaglyph and polarized 3D glasses.
Because of their integrated electronics and batteries, early shutter glasses were heavy and expensive. However, design improvements have resulted in newer models that are cheaper, lightweight, rechargeable and able to be worn over prescription lenses.
From brand to brand, shutter glasses use different synchronization methods and protocols. Therefore, even glasses that use the same kind of synchronization system (e.g. infrared) will probably be incompatible across different makers. However, efforts are being made to create a Universal 3D Shutter Glass.
Some active shutter 3D systems may exhibit depth distortion of screen objects moving horizontally, due to a timing mismatch between the capture (recording) and playback of sequential left-right frames. An object moving laterally in one direction may protrude while in the other direction it may recede into the screen. A static image does not have this distortion.

This permits using relatively inexpensive passive viewing glasses, similar to those for movies. The principal disadvantage is that each polarization can display only half as many scanning lines.
Advantages:
- Generally inexpensive.
- Do not require power.
- Do not require a transmitter to synchronize them with the display.
- Do not suffer from flicker.
- Lightweight.
Disadvantages:
- The images for polarized glasses have to share the screen simultaneously, and therefore cannot have full resolution delivered to each eye simultaneously. A full 1080p picture results from image fusion.This disadvantage does not occur on projections where each pixel can contain information for both eyes.
- Associated with the headaches many people attribute to 3D viewing.
- Narrow vertical viewing angles compared to Active shutter 3D
Polarized Goggles are used to see stereoscopic Images and Videos Or movies ,According to my Experience ,This is the Best Viewing Technology . Smooth and Clear ,Headache is very little and the 3D viewing is The Best .
If you Have this Polarized 3D Glases you can check out the Below Stereo Video Link .
If You Are not able to see this video in 3D , then go to Setting -> option -> 3D -> and Switch to Interleaved.
Now the Second Part of Polarized Viewing System .
For this You Need to Have a 3D Led Monitor .
My Choice is AOC 3D Monitor
I am Using The AOC 2367PH 3D Led Monitor.
its a Damn Good Monitor .
This are the Four Switches on the Back of Led
the Option for 3D in this Monitor Are
- Only 2D
- 2D to 3d
- 3D Side by Side (SBS)
- 3D Top/Bottom (T/B)
- Only 2D is by Default.Normal Desktop
2D to 3D is an feature which converts the normal 2D Pics ,Videos ,Screen to 3D which is only 40% Effective ,You will get a Feel of 3d But Not the Perfect 3D Viewing Experience.
- 3D SBS
This is video style wich runs in 2 partition and for viewing it you have to join the video in One by switching it to 3D Side-by-Side mode which is available in your monitor.
Spare me if i made any writing Error.
In AOC Monitor ,in the Back side there Are 4 switches ,which have options for
- Menu/Select
- Volume/UP
- 2D - 2D to 3D - 3D(SBS) - 3D(T/B)/Down key
- Switch On/Off
Then Choose the 3rd Option with the UP and Down Key and select 3D SBS & Put on the Polarized Glasses and You will be able to See the Best 3D in Action.
If you come across a 3D Video which is in Top /Bottom Format then the Same Procedure and choose 3D T/B option .

3.Active Shutter Technology

It works by only presenting the image intended for the left eye while blocking the right eye's view, then presenting the right-eye image while blocking the left eye, and repeating this so rapidly that the interruptions do not interfere with the perceived fusion of the two images into a single 3D image.
Advantages:
Unlike red/cyan color filter (anaglyph) 3D glasses, LC shutter glasses are colour neutral, enabling 3D viewing in the full color spectrum.Unlike in a Polarized 3D system, where the screen resolution is halved when the images are combined, the active shutter system retains full resolution by combining the images over time.
Disadvantages:
Until recently, the method only worked with CRT monitors; some modern flat-panel monitors now support high-enough refresh rates to work with some LC shutter systems. Many projectors, especially DLP-based ones, support 3D out of the box.

This Are Expensive and You Have to Charge it Regularly .
---------------------------------------------------------------------------------------------------------------------------
My Opinion --- The Second Option ,that is Polarised Glasses .
This are the Best Glasses Availaible and Provides Clear and Smooth Effects .
Regarding the Moniter ,My Vote Goes To AOC 2367PH 3D Led Monitor .
The Package Comes With 2 3D Polarized Glasses (1 full Glass and other a Glass clip which can be attached to any Numbered Spectacle )
India Price is Around Rs 14000 as of 28 March 2014.
I am not a sales guy of AOC Nor am i working in that Company.
I am Using it and I am Just Guiding those who are Interested in 3D Buying with My Little Experience.
Thank You
