One of the most confusing things about buying a TV is all these different terms
0:04
that get thrown around. LED, LCD, plasma, CRT, the BGS. We're going to
0:10
explain what all those things are as fast as possible. The most common
0:14
display type these days are LCDs. That stands for liquid crystal display. It
0:18
involves having a backlight, usually fluorescent, with an LCD screen in front
0:23
of it. The LCD screen is where the images and the colors actually come
0:26
from. One of the drawbacks of LCD is that it can never produce true blacks
0:32
because that screen would have to become completely opaque or solid in order to
0:37
get a true rich deep black. However, the advantages of LCD are that it's
0:41
relatively inexpensive these days and unlike traditional CRT tube TVs, they
0:46
are extremely thin. The next TV type, LED or light emmitting diode, is
0:50
actually a bit of a misnomer because an LED TV is just an LCD TV. that is a
0:55
liquid crystal display panel with an LED backlight instead of a cathode
1:00
backlight. This gives it a couple of advantages. Number one is lower power
1:04
consumption. Number two is even thinner form factors because they're not nearly
1:09
as bulky. And number three is that with many high-end LED arrays in the back of
1:14
the TV, you can actually enable a feature called micro dimming. So that is
1:18
to say that the LCD goes black and the LED behind it in that zone can even turn
1:24
down or turn as low as it can to make the blacks much more true and much more
1:28
rich. So LED TVs tend to be just higherend LCD TVs. Plasma TVs have
1:34
turned into a bit of a value option over time. They have excellent black levels
1:39
because instead of relying on a backlight with a screen in front of it,
1:43
the plasma display actually outputs its own light. So that means it doesn't have
1:48
to output light. So very very deep blacks. You also get extremely fast
1:52
response times making plasmas great for gaming. The disadvantage of plasmas is
1:56
that compared to especially high-end LCD or LED type TVs, the colors can be a
2:02
little bit washed out if you are in daylight or an environment where you
2:06
don't have a a dark home theater to watch it on. And because the front of
2:11
the display has to be glass, they tend to get a fair amount of glare, making it
2:16
more difficult again if you don't have true blackness to watch your TV in. At
2:21
the last minute, I decided we should include a segment on OLED. So, while
2:24
it's not really available on the mass market today, OLED addresses some of the
2:28
issues with LCD, such as slow response time, so much much sharper movement.
2:33
It'll be great for 3D as well as the not
2:36
very true to life deep blacks because OLED like plasma emits its own light
2:41
rather than relying on a backlight with a panel in front of it. But it's very
2:47
very expensive right now. As always guys, don't forget
