MERITS AND DEMERITS OF 3DTV

There are many popular brands that are producing these televisions. If you are not sure whether you are ready to purchase a 3D television, then read below to find out the benefits.How Does 3D TV Work?It is important before purchasing a 3D TV to find out how it works and what makes it different from a standard television. All traditional televisions function in 2D, which show height and width. A 3D TV allows viewers to watch television in height, width and depth.
 
The concept of 3D TV comes from the human anatomy.Basically, our eyes are set about seven centimeters apart. Each eye captures a different image as each eye views an image from a different angle. Once the brain receives these images, they are blended together to create a sense of depth. Basically, the same is done to create this technology.Two different images are used, one for each eye, of the same scene. When the 3D television glasses are worn, the images are fused and it becomes a single 3D image. Not everyone is able to see 3D images because they suffer from stereo blindness. However, this only happens to a small percentage of the population and is rather uncommon.Tech TalkThere are three types of 3D technologies to choose from which include anaglyph, stereoscopic passive polarised and stereoscopic active. The best is to use stereoscopic active technology for 3D television viewing.You can choose one of these great technologies when you order your new television which can handle the capacity of 3D technology. If you do not want to watch your television in 3D, then no problem – you can always revert back to watching television in 2D. You will still receive exceptional television quality and picture while watching in 2D mode.There are four brands that currently manufacture 3D TVs: Samsung, LG, Panasonic and Sony. However, it probably won’t take long for other manufacturers to follow.These televisions all differ, so it will be up to you to make the choice as to which is better for you. The Samsung offers three-dimensional capabilities on LED, LCD and plasma televisions. The LG and SONY televisions offer 3D on LED and LCD televisions, while Panasonic only offers 3D TV on plasma screens

3D TV AdvantagesIf you want to watch 3D content then you will need a 3D TV. There will be 3D to watch but there won’t be a whole lot of it for awhile yet. Discovery is planning a 3D network and many of the 3D movies currently in theaters will be available on Blu Ray Disc.As with any new technology 3D will get better, more widely available and less expensive after a few iterations. 3D content will also be expanding in the future ad more content means more reasons to own a 3D HDTV. As the technology improves some internet connected TVs should be able to update their firmware and improve 3D processing so for the early adopters out there their TVs may be able to gain from future improvements.If you’re planning on buying a top tier TV in 2010 you’ll be getting 3D capability with your purchase. All of the flagship lines this year have 3D so you can consider that a bonus. Check with the manufacturer of your Blu Ray player as many of them will be getting 3D firmware updates and also see if your HDTV provider will be offering 3D and if you will need an upgraded cable or satellite box to view it. If you’re going to buy a top tier TV this year you might as well get the most of it.At bottom of article add: Right now the premium for 3D TV compatibility is around $400 depending on whether the TV is LED, plasma or LCD. Obviously purchasing a 3D TV future proofs you for the possibility that the technology takes off and content for 3D TV explodes.3D TV Problems, Issues and ConcernsWith the massive marketing push behind 3D TV you’ve almost certainly heard all the upsides to watching television in 3 dimensions. For a balanced approach we’ve researched some of the problems with 3D TV.It’s ExpensiveFlat panel HD TVs have seen significant price drops over the last few years, it’s pretty easy to find a 50″ flat panel TV for under $1000, not too long ago you could buy a fairly nice car for less than a flat panel TV. Even though manufacturers told us that 3D would not add to the price of the TV at CES we are finding that this is not the case. The 3D enabled models make up the top tier of most manufacturer’s offerings this year (Samsung has the most different 3D capable lines) and though even top tier model prices have been dropping over the years this is the first year we’ve seen a significant rise in pricing from one year to the next.Many people have just recently updraged from standard definition to high definition television and HD components such as a Blu Ray player. To go from 2D to 3D requires at minimum a new, expensive television purchase. Consumers may also need to purchase new components although some recent Blu Ray players will be able to download a firmware update that will make them 3D ready. 3D glasses will also be required for each viewer. For a family of 4 this could add up to nearly $1000 in glasses alone.Lack of ContentWhile you can go out and purchase a 3D TV today you would not find much to watch on it. 3D Blu Ray discs won’t be making an appearance until the 2010 holiday season, 3D video games will show up around the same time. ESPN has a 3D channel so some select sporting events, such as the World Cup and The Masters, have been broadcast in 3D. More 3D channels from Discovery and Disney are planned as future offerings but this shows the limited content available at the time of writing.3D content is expensive to produce, it requires special equipment for filming and post and the usefulness is limited for a lot of programming. It’s subjective of course but how much will 3D really add to today’s bevy of medical and crime dramas, reality shows and sitcoms?Corrective Lens WearersAnyone who wears glasses and has been to see a 3D movie or other production knows that wearing 3D glasses over your glasses is both uncomfortable and awkward. Try as they might to make a pair of 3D glasses that work well for the many near and far sighted people out there it just hasn’t happened yet.Eye strain, Headaches and Nausea3D works by tricking our eyes and brains, it uses the natural way we process depth to create an appearance of 3 dimensions in a 2D screen. In extended viewing, even for only the length of an average movie, this can cause many people to feel nausea or get a headache associated with eye strain. Our brain can naturally compensate for some minor eye problems such as a muscle imbalance but the process involved in creating the 3D illusion can bring previously unnoticed eye problems to the forefront and overwork this natural compensation resulting in a headache. More significant eye muscle imbalances can negate the ability to see 3D content entirely.Multi-TaskingMore and more people today watch TV with a computer in their lap or a smart phone close at hand. In today’s connected, digital world people update Facebook or Twitter or chat on a forum with other fans while they watch their favorite shows. 3D glasses don’t work well with non 3D content and you’ll be taking glasses on and off or trying to look around them to multitask while you watch TV. If this paragraph describes you watching TV then 3D may not be ideal.
It’s NewAny early adopter knows that when you purchase the first generation of a new technology you not only pay extra for that privilege, you also get all the bugs inherent in something new. Technology always both improves and gets less expensive. With today’s internet connected televisions software problems can be corrected with an update but you’ll be stuck with any hardware related issues that crop up. There’s also the possibility that 3D TV won’t catch on and though you’ll still have a nice 2D television, you’ll have paid extra for a feature you aren’t using.
