What is the difference between a Lcd tv and a Led tv?




Some guy


Im getting one for crimbo, also what is a plasma tv, i want the best one stated


Answer
LCD and LED tvs use exactly the same display but they are lit differently.

LCDs use lights a bit like 'cold cathodes' to light up the screen, but LED, as its name suggests uses an array of LEDs either behind the screen (backlit) or around the edges of the tv behind the bezel (edge-lit).

LCD tvs are cheaper to buy initially but on estimation cost roughly 30-40% more to run than the equivelant sized LED backlit screen.

Also LEDs can be turned off independently, so you get deeper blacks on the screen.

Plasma is a tv which uses gas and light phosphors to produce a picture. They use on average 60% more electricity than LED backlit tvs, and also most of them suffer from reflection from room lighting or sunlight. There is one slight plus side in that they are the cheapest to buy of the three nowadays when comparing size for size.

If you must get a Plasma get a Panasonic G series or above, since these are about the same energy effiency as a regular LCD but also have an different perspex on the screen so that it is less reflective, which allows more vivid colours to be seen on screen. Many people still believe that Plasma TVs are best at motion and have more realistic colour on flesh tones. These TVs however are priced at about the same level as LED tvs.

Lcd, plasma, or led??

Which kind of tv is best?


Answer
LED because:
- They allow for deeper blacks, brighter whites and more vibrant, vivid colours because of the very high contrast ratio, making lighting and overall picture more realistic, and blacks are almost pure black when watching TV in the dark, unlike plasma and lcd where it is a washed out grey
- LED TV's are more efficient as less energy is needed to power them
- LED TV's are able to be made much thinner than lcds and plasmas because of its properties (less panels are needed with LED tvs such as diffuser panels and lighting tubes, which take up lots of thickness)
- LED TV's offer a more crisp, sharper images because less panels are needed. With Samsung LED TVs, they don't add an extra glass layer like you have to do with lcds and plasmas, so you get a clearer, sharper picture, and see a pure, vivid picture.
