What is a LED TV?LED TVs are a type of LCD TV having light-emitting diode (LED) as a light source for backlighting as opposed to the more common LCD TVs on the market which use fluorescent lamps as light source for illumination in displaying an image.

Benefits of LED TV:

- slim
- thinner housings
- lighter in weight
- wider color range
- better dynamic contrast
- sharper images
- higher brightness
- deeper blacks
- longer life
- lesser heat generated
- lesser time to power on and off
- lower power consumption
- savings in your electric bills
- more energy efficient
- more environmentally friendly

Major disadvantages:
- more expensive
- sound quality sacrificed over slimness

3D HDTV LED and Plasma

Major advantages 3D TV:
    - supports Internet TV
    - internet applications available
    - "real, true to life" viewing experience
    - multi-view capture representation
    - images and videos viewed in three dimensions
    - more natural and realistic feel of viewing
    - slim body and thinner housings
    - wider color range
    - better dynamic contrast
    - sharper images
    - faster refresh rate
    - four or more HDMI ports
    - state-of-the-art technology is implemented

Major disadvantages of 3D TV:
    - costly (pay the price of today's technology)
    - some requires special 3D lenses (which is sometimes not included in the price, and you have to buy it separately)
    - some requires 3D projectors which are pricy and expensive
    - some require sync units to synchronize the 3D images generated
    - some require special 3d transmitters and glasses
    - some require active shutter glasses (requires batteries)
    - some models have a flickering light effect
    - in some models, viewers are restricted only to a certain angle and distance, which of course would be unfair (in the sense that 3D images or videos don't look good if viewed at a different angle and distance) to some viewers in a home theatre system which have many family members and visitors (viewers).

Which TV is better for me?
Bottom line is......Which TV should you buy? Which television is the right one for you?

The answer is up to you, the buyer.

You know your room lighting and air pressure conditions, the applications where you want to use your Tv for, the dimensions and space requirements or limitations of your office, bedroom or living room, the price depending on your allowed budget, the length of time (life span) you are expecting from the Television set, power consumption (electric bills), health and safety issues (like radiation, etc.), and a lot more preferences that can only be determined by you, the buyer.
