TELEVISION sets have been around for many years since the 1960s, back in the days we used to have (CRT) Cathode Ray Tube TV.
A box like TV set, the oldest and most widely used TV before the invention of the flat screen television that is typically capable of high-definition display and can play content from a USB device.
Nowadays, we have so many different options for buying television and sometimes we get caught up in the Jargon like LEDs, LCDs, Plasmas, and DLP. Most times we don’t know what choice to make so sometimes we just buy the closest cheap.
It’s good to have many different buying options but it is bad when the consumers have less knowledge about what they are buying. Many don’t even have the slightest idea about their differences and yet all these TV sets are made from different technologies. So it is important to understand what can work best for you.
Let’s have a look at some of the things to consider when looking at televisions and see which one suit you best. First of all let us define these Jargon terms so that we are on the same page of comprehension;
The term ‘LCD’ Stands for “Liquid Crystal Display.” LCD uses liquid-crystal displays to produce images.
Normally used in laptop computers and TV screens. LCD televisions are thinner and lighter with a special flat panel that can block light, or allow crystals to pass or block light to produce images. LCD crystals do not produce their own light, so an external light source like a florescent bulb is needed to create an image.
LED stands for “Light Emitting Diode,” these TVs are not a completely new format of TV, they are all part of the LCD TV family. Instead they are simply an updated version of the previous LCD generation.
The display screen on a LED is a liquid crystal display, the same as on any other LCD TV. The main difference is that instead of being illuminated by a flourescent bulb from behind, they are lit by an array of LEDs (light emitting diodes).
These are far more efficient and smaller in size, meaning the TV can be narrower. LED TV is the most popular on the market due to its cost, size and versatility, although it is not the highest quality image available.
Plasma TV uses an array of cells for cell. Each cell is separated by glass panel which is injected with neon-xenon gas and sealed in plasma form during manufacturing. That’s why we have the name “Plasma TV.” When charged with electricity, the gases react and cause illumination in the pixels across the screen.
Plasma is considered superior to LCD & LED in terms of contrast and colour accuracy. They are not dependent on back-lights, their technology diverges the intensity of the light to produce its own range of colours. It is restricted to larger screens sizes and they don’t reflect as much light as LCD, they are good for dark rooms.
DLP stands for “Digital Light Processing’ and is a method for displaying video using rear projection light. It is based on a semiconductor chip called a Digital Micromirror Device (DMD). DLP is not as stylish as LCD or Plasma TV but has a good picture quality.
Plasma TVs are typically cheaper than LCDs at the same size but sometimes prices can be competitive. DLP is significantly more expensive than LCD, but requires less on-going maintenance.
DLP focuses on the larger sizes that cannot be achieved with LCD or Plasma. Unfortunately they can’t be mounted to the wall like a plasma or LCD. The goodness with Plasma technology though is that it works well on massive screens without losing its quality. The quality of an LCD television deteriorates in very large screen sizes.
The picture quality of an LCD TV is the same as LED TV but their picture quality is not as good as that of plasma TVs, but still good enough for nearly everyone. The difference between the LCD and Plasma display qualities may not be very significant.
Plasma pictures can be viewed from any angle unlike LCD where the light source is usually in the center of the screen. The quality of plasma display doesn’t deteriorate when you move to the side angle of the display whereas LCD will get dimmer or darker as you move away to its sides. The viewing angles on DLPs vary but are typically not as good as an LCD screen. The latest LED TVS have viewing angles that contend plasma TVs unfortunately they are more expensive than plasma TVs.
Plasma TVs generate more heat than other TV technologies because of the phosphors that create a good image
LCD TVs will last twice as long as a Plasma TV, the lifespan is longer. A plasma TV is prone to display degradation as plasma cells burn out leaving permanent black cells on the screen display which kill the picture and colour quality. LCD is not prone to such issues. The lamp that projects the light can go bad but in most cases it is replaceable.
DLPs are lit by replaceable bulbs which need to be replaced every couple of years. Possibly every 2 years and sooner if you watch a lot of TV. Also, if one LED burns out it will be less noticeable.
Plasma uses up a lot more power than LCD TVs, and is based on screen size and brightness. Back in the days some countries had considered banning large plasma televisions.
The Plasma and LCD TVs are so thin and this makes the speakers to be very small, they are not as flat and loud as the other TV’s, especially if there is a lot of noise in the room. Other people connect external speakers for a more surround sound.
DLP TVs are not mounted, they just sit on the TV stand, LCD or Plasma TV can be mounted to the wall, Plasma TVs are usually heavier than LCD screens and may take several people to mount it to the wall.
