With the explosion of popularity in flat-panel TVs the average consumer can feel overwhelmed with the various ones to choose from. The three main units are a Plasma, LCD or LED TV. What's the difference? What works best for you? Follow our TV buying guide below to help assist you in picking the best TV for you.

Plasma television technology is based loosely on the fluorescent light bulb. The display itself consists of cells. Within each cell two glass panels are separated by a narrow gap in which neon-xenon gas is injected and sealed in plasma form during the manufacturing process. The gas is electrically charged at specific intervals when the Plasma set is in use. The charged gas then strikes red, green, and blue phosphors, thus creating a television image. Each group of red, green, and blue phosphors is called a pixel (picture element).

This technology is different from that of a traditional television. A traditional television has a Cathode Ray Tube, or CRT. A CRT is basically a large vacuum tube in which an electronic beam, emanating from a single point in the neck of the tube, scans the face of the tube very rapidly, which, in turn lights up red, green, or blue phosphors on the tube's surface in order to create an image.

The main advantage of Plasma over CRT technology is that, by utilizing a sealed cell with charged plasma for each pixel, the need for a scanning electron beam in eliminated, which, in turn, eliminates the need for a large Cathode Ray Tube to produce video images. This is why traditional televisions are shaped more like boxes and Plasma televisions are thin and flat. A benefit of plasma is that, to the naked eye, blacks are blacker and colors are more vibrant.

An LCD Television is a flat panel television that utilizes the same basic Liquid Crystal Display technology that has been in used for some time in cell phones, camcorder viewfinders, and computer monitors. LCD panels are made of two layers of a glass-like material, which are polarized, and are "glued" together. One of the layers is coated with a special polymer that holds the individual liquid crystals. Electric current is then passed through individual crystals, which allow the crystals to pass or block light to create images. LCD crystals do not produce their own light, so an external light source, such as florescent bulb is needed for the image created by the LCD to become visible to the viewer. LCD televisions can be made very thin, thus allowing them to hung on a wall or placed on small stand on top of a table, desk, dresser, or cabinet very easily. Shop Abt's full line of LCD TVs.

Light Emitting Diode (LED) is very similar to LCD TVs in that they use Liquid Crystals to produce an image. The difference is that the light is emitted through a diode that is brighter, can last longer and uses less energy. They are like little light bulbs, which use very little power compared to the light that they produce. This makes them good for the environment. They are also mercury free-another environmental plus. LED TVs boast the three "C's": color, contrast, and clarity. These TVs can be produced extremely thin which is both space-saving and aesthetically appealing in whichever room of your home.

There are two various ways the LEDs can be lit on the TV: edge-lit or full array. Full array refers to televisions that use a full panel of LEDs to illuminate the pixels. Most of these sets also have local dimming, which means the LEDs can be dimmed in different regions of the panel simultaneously, which improves black levels and picture uniformity. Edge-lit, on the other hand, means the LEDs that illuminate the pixels are located only on the edges of the set.

In general, full-array LED is considered a superior technology when it comes to picture quality, but edge-lit sets have one major advantage: depth. Edge-lit LED TVs can be much thinner than those lit with either a full LED panel or traditional fluorescent (non-LED) backlights. For that reason, most of the super-thin sets you see will be edge-lit. Shop Abt's full line of LED TVs.

Front Screen Projectors
Projection TVs work similarly to the way that projectors in movie theaters do. There is a projector that is mounted on the ceiling in front of a projector screen. The image from the projector is then beamed onto a screen. The better the screen, the better the image and resolution.
A painted, flat wall would work as well but a superior image would be received when using a custom projector screen. A great benefit to owning a front screen projection TV is its capability to create large pictures and allows for easily customizable sizes. Shop Abt's full line of Projectors.

Once you have decided on either a Plasma, LCD or LED TV you can get them in various options, such as the following;

3D TVs
The newest kind of TV to hit the market. To watch movies and other programming in 3D you will need a 3D TV as well as 3D glasses. These glasses are typically sold separately and can get quite expensive. Right now, 3D content is only available as Blu-ray movies. This means to experience 3D on your 3D TV you will not only need 3D glasses, but a 3D movie and a 3D Blu-ray player.

The way it works is when we see images, our left and right eyes merge it into one. To re-create that in high-def, TVs must refresh the picture at least 120 times a second with alternating frames for the left and right eye, which tricks your brain into seeing only one image. Most new TVs are fast enough to do this, but to be 3-D-capable, TVs must include a converter chip and software to break down the signal and separate the left and right images.

The viewer then wears what are called, active-shutter glasses, which rapidly block one eye at a time so that each eye sees only the frame meant for it. The glasses contain two small, black-and-clear LCD lenses that darken or lighten when a radio or infrared pulse from the TV (or an add-on emitter) signals that the image is changing. 3D TV content looks great but is currently not plentiful and additional glasses can cost up to a couple hundred dollars extra.

TV Combos
TV Combos are an excellent selection of TVs for anyone that is looking to be multi-functional while saving space, such as in a kitchen or dorm room. TV combos are flat panel TVs that also play DVD movies with their built-in player. Typically the DVD drive is located on the side of the unit and works as a slide-in/slide-out function to play your favorite movies without the need for an additional DVD player.
