buying an LCD TV
In terms of picture quality, LCD technology continues to improve year on year. Traditionally, LCD TVs haven’t been able to match the deep blacks of plasma sets, but larger LCD screens tend to offer excellent HD pictures. Conversely, smaller LCD screens tend to produce excellent results for standard definition picture quality an important consideration given that most TV content these days is still non-HD.

buying an LED TV
LED TVs have taken the market by storm, and since Sony and Samsung first debuted the technology all of the major TV manufacturers have launched their own LED sets. To give an LED TV its full name is more of a mouthful: LED-lit LCD. LED TVs still employ standard LCD TV technology with one crucial difference – the handful of traditional back light lamps that illuminate the screen have been replaced by hundreds of smaller LEDs.
The benefit of using the LEDs is that it allows the TV set to be significantly slimmer than most LCD or plasma sets. This allows for ultra-stylish slim screens that look great mounted on a wall. The other benefit of LED screen technology is that it is significantly more energy-efficient than either LCD or plasma technology. LED sets tend to be much more forgiving on your electricity bills. LED TVs tend to produce excellent colours and sharp detail, though like LCD sets, they tend to suffer from poor viewing angles. Often, if you’re not sat head-on to the TV, the picture quality will deteriorate, which is worth considering if you’re buying a TV for a wide living room.
For now, LED TVs are still more expensive to buy than plasma sets or traditional LCD TVs.

Screen resolution is what indicates the picture quality of a TV. The resolution is made up of lines of pixels that display the picture. The greater the resolution the higher the picture detail will be. The resolution of a standard definition broadcasts is 576i (576 lines of 720 pixels each). HDTV is broadcast in 3 different formats; 1080i , 720p, and most recently 1080p. 1080i uses an ‘interlaced’ system which breaks the image into 2 fields and displays ‘odd’ and ‘even’ fields alternatively. 720p uses a ‘progressive’ system which displays each frame of the image as a whole.
full HD 1080p
A significant number of televisions are also 1080p or Full HD compatible.
How does it work?
active 3DTelevisions that use active 3D glasses work by displaying an image for the left eye and then one for the right eye, alternating in very quick succession. The 3D glasses contain shutters that open and close in sync with the images displayed on the screen to ensure that the left eye sees the image for the left eye and the right eye sees the image for the right eye. Since these televisions display full screen images they are generally able to deliver better quality pictures than passive 3D sets.
passive 3DThe alternative to an active 3D TV is a passive one, so-called because the glasses do not have active shutters to send the correct image to each eye. Instead, passive 3D televisions show one image for the left eye and one for the right at the same time. The 3D glasses have filtered lenses that ensure that each eye sees the right image. The downside of passive 3D is that because two images are being shown onscreen at the same time the resolution of the picture is halved so the images are not in full HD.
3D without glassesThe dream for technology companies is to remove the need for glasses entirely. One way of doing this is by using lenticular lenses, which are shaped so that a different image is displayed depending on the viewing angle. Toshiba is using this technique in its glasses-free 3D TVs. However, the largest display is 21 inches - Toshiba says it will take time to make these displays affordable at larger screen sizes. A similar glasses-free 3D effect can be achieved using a parallax barrier, which sits on top of an LCD display to create a 3D effect - this is the approach that Nintendo has taken for the 3DS.
what do i need?To watch 3D in your home you'll require a 3D ready TV, a 3D source such as Sky 3D or a 3D compatible blu-ray player, 3D glasses for your TV set and a compatible HDMI cable to transfer the 3D signal to your TV.
