If you are in the market for a new television, there’s a good chance you have been looking at purchasing an HDTV set. HDTVs are the latest type of technology to hit the market, and they offer the best of the best in terms of quality and sound.
There is, however, a good chance you are confused between purchasing a plasma, LCD, or LED television set. It can be hard to tell the different just by viewing the sets in the store. A lot of times, if you ask an employee, their answers could be confusing and full of technological jargon. So, we have the answers to help you in purchasing the television set that meets your needs.
Let’s start with plasma. In the simplest terms, a plasma display panel (PDP) is a flat-screen display common to most television sets. The thing that sets them apart is the technology, known as “plasma,” that uses small cells containing electrically charged ionized gases.
There are many advantages to using plasma. The picture quality is superior, there is less visible motion blur due to the high refresh rates and response times, and it is capable of producing deeper color saturation.
The disadvantages include screen burn-in, which means the screen will continue to show an image even if the television is turned off, more electrical power than using an LCD TV, and limited screen pixels.
Shortly after plasmas were released, liquid crystal display televisions (LCD) were released. These HDTV sets use an LCD display technology that allows them to be thinner and lighter than previous sets currently available on the market. Similar to the plasma, LCDs are offered in a flat-screen display, but instead of plasma technology, it uses liquid crystals. LCD televisions were most commonly used in computers prior to being released in a television set.
LCDs are by far the highest selling televisions due to their bright images, low electric emissions, screen shape, and the fact that they take up about 40 percent less desk space than the typical box televisions. LCDs will also cost you the least amount of money to purchase.
They too, however, have disadvantages. The aspect ratio and resolution are fixed and cannot be adjusted, the black level is not as sufficient as the plasma, producing duller grays and blacks, and it has a slower response time than the plasma, which can make for image degration for moving or rapidly changing pictures.
To improve upon the LCD, LED televisions were released. These televisions are much more expensive, but offer an LED backlighting instead of the cold cathode fluorescent (the lighting used in an LCD screen). The picture quality is based off of new technology called TFT LCD, which is an independent backlight. So the main difference between an LED and LCD is the back light used to produce a bright picture.
The advantages of an LED are that they last longer, the picture will be brighter, it has better color contrast, and it’s thinner, uses less power, and is more efficient than an LCD or Plasma.
It comes, however, at a much higher cost. In addition, the heat from the LED chip can actually cause it to deteriorate over time, making the set not last as long as an LCD or plasma. Too much heat can also cause the LED to shift colors and change the screen solution.
So what type of HDTV that is best for you depends on how much you are willing to pay, what kind of picture quality you are looking for, and how long you want the life of the television to last. If you are on a budget, LCDs offer you a lot of the qualities an LED has without the cost. If you are looking for a quick fix, plasmas are reliable televisions that will offer you decent picture quality and last for a long time.
