Everybody that wants to build a home theater, always want for the best technology that they can afford. But for the best technology absolutely need extra money. In home theater always need a display systems. Do you really need the latest technology when it comes to home theater display systems ? Let's see the different.
CRT or cathode ray tube is the old standard for televisions. The principle behind it is a vacuum tube that consists of an electron gun that is directed towards a screen coated in phosphor. The electron gun fires electrons at the screen causing the phosphor to heat up. This action causes colors on the screen which are used to produce an image that you watch.
LCD or liquid crystal display is a large amount of tiny liquid crystals that are held between two electrodes. When a charge is passed from one electrode to the other via the liquid crystals they react to the charge. This reaction causes light to be emitted which creates an image that you watch.
The first thing that you will immediately notice about CRT TV's are that they are far cheaper than LCD TV's or any other latest technology. This is so for two reasons. The first is that the new technology has cost a lot of money to develop so the makers of these televisions have to charge a premium. This price will drop over time. The other reason is that a lot of marketing has gone into the new technologies so retailers are finding it hard to move CRT TV's. The bottom line if budget is a factor is that CRT is still the way to go.
Another thing About CRT's is that they are large and bulky. They need to be to fit in the vacuum tube. This means you need plenty of space to put them in. One of the majors benefits of LCD technology is that the television is a flat panel. It can be placed on a wall are does not take up space. If you have a small apartment or house then this might be a consideration.
CRT TV's have a wider viewing angle than LCD. Thus if you are off center with an LCD the vision might be distorted. Not so with CRT.
LCD TV's have excellent resolution. Whereas a CRT TV might have a resolution of 480, LCD can have up to 1080. They will also use the progressive scanning method as opposed to interlacing giving a more fluid image.
CRT technology has a better contrast ratio than LCD. This means there will be more distinction between the blacks images on the screen. Again, this will make things stand out better in dark movies.
LCD technology has a greater range of colors giving a vibrant picture as opposed to CRT.
Clearly LCD are the latest technology. More money will be put into improving the deficiencies of the technology so it will improve over time. The price will also drop. If, however, you are on a budget and you do not plan to view HDTV in the near future you can't go past the low prices of good quality CRT televisions.
