With high definition television booming, we have seen LCD, plasma, LED and OLED TV sets hitting the high street. But what’s set to be the next big thing in the world of television, could it be 3D TV?
With the likes of Sony, Panasonic, Samsung and LG all showing us their own variations of 3D television it would seem momentum is beginning to build.
Hollywood also seems to be pushing 3D with a recent spate of 3D movies showing in our cinemas. Couple this with work that TV broadcasters are doing testing the filming and broadcasting of live TV events in 3D, it seems we are getting a glimpse of the direction we are heading.

OLED TVs are the Future
OLED TVs are organic light emitting diode televisions and they are the future of television. OLED TV technology has so many advantages but the one that stands out is – backlighting.
The lighting source is crucial to the operation of LCD TVs, without light LCDs cannot display anything. However the fluorescent lighting in LCD TVs is the most common point of failure. When it fails, the fluorescent lights need replacing and in most cases this is not cost effective and so it renders the TV defunct.
This is where OLED TVs have the potential to revolutionize the TV world, because they have no back/sidelights they cannot fail and the power consumption is drastically reduced.
Recently the introduction of LEDs as a light source in TVs has changed the profile of TVs allowing them to be made a lot slimmer. However because OLED require no lighting, they can be made a few millimetres thin. OLED TVs also have better picture quality then other types of sets. Their contrast levels can produce true blacks, and have lighting fast refresh rates.
The problem with OLED TVs relates to production costs and reliability. There are prototype models available with smaller production models in the pipeline. But as soon as TV manufacturers like Samsung and Sony have perfected this technology and production techniques then we will see the explosion of OLEDs into our homes.

LED Technology Used in LED TV
LED monitors and displays are common-place in the computing world. They provide sharp images and great contrast levels compared with standard LCD monitors. The difference with standard LCD and LED displays is with regards to the technology that is used to light the displays. LED displays still utilize LCD panels but they use light emitting diodes (LEDs) rather than fluorescent lights to provide the back or side lights. Due to the use of LEDs, these types of displays produce better quality of pictures and are beginning to truly rival plasma televisions.
As is typical with the introduction of new technologies to the marketplace, displays which LED employ LED technology are still expensive. But as popularity increases and production methods are improved this situations will improve. Also it is worth noting that LED displays are not currently available for screen sizes much bigger than 40 inches.
For the more eco-friendly of consumers, it is pleasing to know that LED technology is playing its part in helping the planet as LEDs have improved the energy efficiency by up to 30% when compared with similar fluorescent LCD displays. When viewed as a long term investment the cost saving this reflects is significant, especially considering that an LED TV or display would expect to have a longer life than previous fluorescent lit models.

Which Full HD Plasma TV
Plasma televisions have advantages over LCD televisions, however they do also have some negative points.
The plus points of Full HD Plasma TV sets include the availability of very large screen sizes (60inch+ plasmas are available). Plasmas are also capable of better colour reproduction producing very intense natural images. When compared with LCDs they have superior contrast ratios and are capable of displaying very dark blacks. They are also considered better at showing rapidly changing images, (however LCDs have improved in this area with faster response time).
These benefits do come at a cost, they are more expensive compared to LCD equivalent models, and especially with the large screen sizes available they can cost upwards of $6000. It is also said that plasmas suffer from screen burn, but for typical usage this is no longer a real problem. The only other possible disadvantage of plasmas is they are less energy efficient.
If you are considering buying a plasma, because of the premium price you will have to pay it would definitely be worth viewing one for yourself to compare to LCD equivalent displays. This way you can judge for yourself if the picture quality justifies the higher price.

A Guide to Full HD LCD TV
LCD (liquid crystal display) TVs have many advantages and some drawbacks. The first is the choice and price, Full HD LCD TV sets come in the greatest choice of screen sizes and price range to cater for any budget or application of use.
Technical features are that they have a good display brightness and power consumption. One possible negative might be the ability to display fast moving images (however LCD response times have been improved, so that this is no longer a real issue). Another might also be related to contrast ratios and the failure to display true blacks (but again with innovations such as localized dimming this has been improved).
When it comes to choosing an LCD display know your budget before you start. The get yourself down to local TV showroom because there can be no substitute for the appreciating a TVs qualities with your own eyes.
