One of the most confusing things about buying a TV is all these different terms
that get thrown around. LED, LCD, plasma, CRT, the BGS. We're going to
explain what all those things are as fast as possible. The most common
display type these days are LCDs. That stands for liquid crystal display. It
involves having a backlight, usually fluorescent, with an LCD screen in front
of it. The LCD screen is where the images and the colors actually come
from. One of the drawbacks of LCD is that it can never produce true blacks
because that screen would have to become completely opaque or solid in order to
get a true rich deep black. However, the advantages of LCD are that it's
relatively inexpensive these days and unlike traditional CRT tube TVs, they
are extremely thin. The next TV type, LED or light emmitting diode, is
actually a bit of a misnomer because an LED TV is just an LCD TV. that is a
liquid crystal display panel with an LED backlight instead of a cathode
backlight. This gives it a couple of advantages. Number one is lower power
consumption. Number two is even thinner form factors because they're not nearly
as bulky. And number three is that with many high-end LED arrays in the back of
the TV, you can actually enable a feature called micro dimming. So that is
to say that the LCD goes black and the LED behind it in that zone can even turn
down or turn as low as it can to make the blacks much more true and much more
rich. So LED TVs tend to be just higherend LCD TVs. Plasma TVs have
turned into a bit of a value option over time. They have excellent black levels
because instead of relying on a backlight with a screen in front of it,
the plasma display actually outputs its own light. So that means it doesn't have
to output light. So very very deep blacks. You also get extremely fast
response times making plasmas great for gaming. The disadvantage of plasmas is
that compared to especially high-end LCD or LED type TVs, the colors can be a
little bit washed out if you are in daylight or an environment where you
don't have a a dark home theater to watch it on. And because the front of
the display has to be glass, they tend to get a fair amount of glare, making it
more difficult again if you don't have true blackness to watch your TV in. At
the last minute, I decided we should include a segment on OLED. So, while
it's not really available on the mass market today, OLED addresses some of the
issues with LCD, such as slow response time, so much much sharper movement.
It'll be great for 3D as well as the not
very true to life deep blacks because OLED like plasma emits its own light
rather than relying on a backlight with a panel in front of it. But it's very
very expensive right now. As always guys, don't forget
