Understanding HDTV
-
The HDTV is a popular type of television. High Density Television (HDTV) is a type of digital television that offers high-quality pictures because it has a higher-than-average number of lines in each frame. This gives pictures more detail. HD televisions generally have between one and two million pixels per frame, which is about five times more than a standard TV. This HD technology was introduced to the United States viewing audience in the 1990s. Plasma and LCD televisions are two types of HDTV.
Plasma TVs

The plasma TV is known for its deep blacks. Consumers who purchase plasma TVs frequently do so because of their size, their picture quality and their price. To get such a clear image, the technology uses electrodes to initiate electrical pulses that excite rare natural gases such as neon and xenon. This causes them to glow and to produce light that radiates through thousands of solitary pixel cells. The light illuminates blue, green and red phosphors of each cell in the proper balance to create a correct color sequence.
The blacks are very black, and consumers find that the plasma TV is perfect for movie watching in a dark room. It offers optimal visuals even on gigantic televisions. It also tends to come with a lower price tag than the LCD television. In the past, consumers have had some problems with image retention and screen burn-in. Engineers are working on this problem and have come a long way. Plasma TVs now have a pixel orbiter that moves each picture more quickly. This reduces burn-in, but still does not completely prevent it. A plasma TV is also not ideal for high altitudes. The pressure differential between the gases can cause an irritating buzzing noise at high altitude. If you think altitude might be an issue for you, check the manufacturer's ratings for altitude parameters.

LCD TVs

The LCD TV uses less energy. The liquid-crystal display television (LCD TV) works by filtering white light. Liquid-crystal filled cells are hit by an electrical charge, and they untwist to a certain degree that filters white light, which is generated by a lamp that is behind the screen. Consumers who purchase the LCD TV appreciate the fact that it is very energy efficient -- which is good for the environment in addition to keeping electricity costs down. Images on the screen tend to have more gray than a plasma TV. However, an LCD TV has a less reflective surface than the plasma TV, making it easier to watch from all angles. Burn-in is not an issue with an LCD TV since it works by filtering out colors, not creating static images.
The Best Television For You

Find the perfect TV for your family. Both the LCD and plasma TV are excellent viewing choices. When choosing one, it's important to determine your own unique criteria. If rich colors and size are most important to you, then you probably want to go with the plasma. If you want to avoid burn-in issues and want to utilize less energy, then the LCD TV is most likely the best choice for you.
