Differences Between Plasma, LCD, and LED HDTV Technology

At the very first stages of HDTV popularity, Plasma was the first screen technology used. Plasma HDTVs use phosphors (super-heated gasses) that when activated, can illuminate themselves and emit light that creates the TV backlight. Plasma is a great way to light up a TV screen, and offers really good contrasts as well as color brightness and brilliance. Some of the downsides however include a distorted picture if you aren't viewing the screen on center. Plasma screens generally offer a higher refresh rate (meaning the screen refreshes very quickly so faster images like sports or video games will not have trailing images or 'ghosts'). Plasma TVs are still popular these days, but mainly because they are cheaper than their LCD or LED counterparts. They also generally have a lower resolution. Many people who bought an HDTV in the early days or up to even a year or two ago still have Plasma screens.
LCD HDTVs, on the other hand, have really become popular because of their relative cheapness (especially since LED screens have become popular) as well as their resolution quality. LCD screens also use less energy than Plasma screens. Instead of using super-heated gasses, LCD screens use several million very little light bulbs. This reduces the need for thick panels (like Plasma screens needed) so LCD screens are generally thinner.
One of the benefits of LCD HDTV screens is their weight. They are much more lightweight than Plasma screens (or the huge CRT screens). Another benefit is the viewing angle. A person can sit at any angle and see the screen clearly. This is a huge factor for those who have big families or large viewing parties.
LED HDTV technology is the "new kid on the block" where they combine the best of both Plasma and LCD screens. LED screens have some of the best black to white contrasts and color brilliance while they also have amazing resolution, sharpness, and refresh rates. LED screens use less energy than other screens, and are more expensive to produce. LED screens are lighter and thinner than LCD and Plasma screens and have no issues with viewing angles. With all of these benefits, LED technology is the most expensive type of HDTV on the market today, however their prices are coming down and are getting more in line with the prices of the other models. Whether you end of choosing a Plasma, LCD, or LED screen, make sure to read the reviews and get the best expert advice in order to help you make a good decision.
