There are a number of different television types on the market right now unlike several years ago when the only real choice in televisions was with the screen size. With the way things have changed however, it is no surprise that many people are looking into HDTV's, but did you ever consider that an HDTV does not necessarily have to be an LCD panel?

HDTV

The first thing you need to know is that an HD TV could be a plasma television. There are a number of features resented in a plasma HD TV that you will not find in their LCD counterparts, though there are a few disadvantages:

Plasma televisions are much brighter than other television types.

A plasma HD TV is more capable of showing black areas than a LCD panel

One disadvantage is the lack of internal speakers, but a good plasma television may have a built in amplifier. This will make it necessary to connect the plasma television to a home theater system, but many believe this small sacrifice is well worth it.

The plasma television uses transistor electrodes for each visible pixel, and this will eliminate the appearance of scan lines across the image. This will make for a much sharper image and a more enjoyable viewing experience.

Plasma screens are capable of accepting signals from the majority of computer systems, and they can work with many of the older formats. Signals such as NTSC, SECAM, BNC, RCA, and PAL can also be decoded easily on a plasma television. It should be noted that HD TV devices do not necessarily have to be flat screen. They can in fact be CRT televisions capable of accepting the 1080p/I or 720p signals. There are not many of these televisions available now due to the LCD and Plasma preference, but they did exist for a short time.

LCD TV

The LCD TV is a bit different from the plasma concept though it is still more than capable of displaying an HD signal. There are many who prefer the LCD TV for their HD viewing, one of which happens to be gaming. As you may have heard, LCD TV panels do not suffer from the well-known burn-in problem that you will find in plasma televisions, which means the television can actually handle still images for a length of time. There are other features in an LCD TV that make them worth purchasing however, even if they do not provide the crystal clear image of their plasma counterparts.

LCD TV is a technology works by producing a black and colored image that is filtered by a white light, and this light is produced by a line of cold cathode fluorescent lamps at the back of the screen which you can generally see by taking a look through the back vents. There are a number of shutters that open and close in order to allow a designated volume of white light to shine through, and each shutter features a colored filter that will remove all RGB from the light. This is what partially allows an image to be maintained, though there is quite a bit of science behind it.

LCD televisions feature all of the standard ports including HDMI, VGA, Composite, Component, S-Video, and audio out.

Most LCD TV's will also feature a USB port that is capable of reading various media types. As you can see, there are a few differences between standard HD TV's and LCD TV's. You must choose according to your needs, and there is an application for either. In the end, you will buy what is right for you, even if that means buying both.
