Some popular myths and realities of 3D TV
After HDTV and Smart TV, 3D TV in market is a new concept. 3D TV is an advanced technology, which are available in Plasma, LCD and LED range in the market. These are slowly catching up the market. This articles details the features of 3D TV and the things to pay attention to before purchasing the 3D TV.
Let us understand first what in effect the 3D TV is. The most apt word for 3D TV is the 'stereoscopic television'. In the conventional HD TV, objects look in 2D (Two Dimensions) whereas in the 3D TV, objects look in 3D (three dimensions) i.e. the effects of depth falls into the vision. You must be remembering supposedly that we used to play with slide rule in our childhoods, which could be the initial example of 3D TV. If we do minus the TV parts, same principle works in the both- two different views of any object becomes distinct to our vision- one is seen by our left and the other by our right side eyes. Our left eye sees the left view in 3D while our right side eye sees right side view. The illusion that forms with this is called the 3D effect. If there is any leakage in both these views, as for instance, the left eye views the right side of object or the right eye views the left side of an object, a ghost image forms up from, Such contamination is called Crosstalk that makes your viewing experience awful.
Are 3D glasses necessary for 3D TVs
Yes, it is required sir! In order to see 3D content in 3D TV, 3D glasses are necessary. 3D glasses are of two types
Passive 3D glasses
These are cheaper and lighter in weight. These are mostly used in 3D movies and theaters. These circular polarized glasses are interchangeable and are used differently in different brands of TVs. Many third parties also manufacture 3D passive glasses. No any type of battery is fitted into it. Several 3D passive glasses come in designer and in clip-on-version. Such viewers who wear glasses regularly wear this glass over and above their regular glasses.
Active 3D glasses
Batteries are fitted into the active glasses, which connect with TV through the infrared or Bluetooth. These need to be activated before their uses. These glasses are costlier but give off the real experience of TV. In addition, there is one more specialty of this that these produce flicker whereas this problem is present more in passive glasses.
Options available for persons already wearing glasses from before
Generally, four glasses of family pack comes with all the 3D TVs coming in market. Some companies are giving two glasses as well. If the family is big, extra glasses will have to be bought. Some third parties companies are making universal glasses too. If you wear glasses already from before these, extra glasses could create problems for you. At that time you need ti fit in contact lenses to see the 3D contents. Apart from this, you can select the clip-on version glasses also. By fitting in these glasses on your present glass, you could derive the pleasure of 3D.
How many types of 3D techno are there
3D technology is of three types namely :
Could 2-D videos be watched over 3D TVs
At present, all the 3D TVs available in Markey have this facility. They are fitted with one conversion2D-TO-3D mode that converts the 2D contents into 3D. In addition, 2D contents on it could be viewed similarly as we see on common TVS. To see 2D content, it is not necessary to sit wearing the 3D glasses. Wear the 3D glass only when you watch the 3D content on TV. You can convert general serials or movies also in 3D version with the help of conversion filter.
Options available in 3D TVs and their price range
3D TVs are available in market in the range of 38 thousand to 3 lacs. 3D TVs come with Plasma, LCD and LED-LCD display. The sizes of which begin from 32 inch to 84 inch. This could be selected depending on the size of your home. In comparisons of LCD or LED 3D TVs (in fact, LED TVs are actually LCD TVs in which, in place of CFL tube, LED lights are used for backlighting), Plasma 3D TVs are far better because due to slow refresh rater in this, problem of blurs do not arise. In addition, the color quality is also excellent whereas, the contrast rate is much more in LED TV in comparison to LCD TVs, hence these are by far better. If you are in a mood of buying 3D TV, there is no comparison of 3D Plasma TV. If you feel the rice is too high, 3D LED could also be a good option.
Could mobile videos be accessed on 3D TV
All the TVs present in market come with smart TV features. You can play the saved movies on your laptop on the TV from the Wi-Fi adaptor. Some have inbuilt Wi-Fi adaptor whereas in some cases, it has to be purchased. Internet could be accessed on it as well. Apart from this, with the help of one advance share cast technology, you can even access on TV the saved videos, games on your mobile, and can watch sports and movies through your mobile.
Does it feel like the cinema
High-resolution video content is required for 3D. The big difference between cinema and 3D TV is the size of the screen and the distance. In the Home 3D TV, whereas the distance has to be kept short in passive glasses, this distance need to be increased a little bit in the 'Active Glasses'.
Games could be played on 3D TVs
Apart from viewing movies videos on 3D TVs, you can also play 3D games. As of the present, no any channel in India broadcasts 3D contents. Some channels are broadcasting 'High Definition Contents'. They are converted into 3D with the help of 2D-to 3D convertor for viewing contents. 3D gaming console is required for playing 3D games.
What to do to view original 3D movie
This one is a big problem. In the absence of 3D channel not being available, we have to depend on '3D-Blue-Ray' DVD. Extremely selective movies, as for instance 'Avtar', 'Ra One', '2012', Life of Pi, Titanic etc are some movies, the 3D DVD's of which have arrived in the market. Most of these are Hollywood movies. In addition, 3D movies come in Blue-Ray–Format, which could be gotten barely below thousand rupees. You will have to either download the 3D content in the 'Main drive' that takes ample space or the other option is the 'Blue-Ray DVD player. Blue-Ray DVD player gives 1080 pixel full resolution. 3D 'Blue Ray' player is available in market in the range of 5000-8000 rupees.
Who should not buy 3D TV
Some persons suffer from the problem of stereo blindness. They cannot catch illusions generated by the 3D glasses. To them even the 3D contents also look like 2D contents. Before purchasing 3D TV, each member of family should get stereo blindness problem checked through demo, because this problem could be detected only from demo.
Some health risks are also attached together with this. Children and pregnant women should avoid watching 3D TV contents. Some persons can feel motion sickness, eyestrains, and postural stability problems. 3D effects could increase your heartbeats too. Watching 3D contents for longer hours could cause fatigue and headache. Some viewers could feel disorientation problem.
