WEBVTT 00:00:00.240 --> 00:00:07.040 One of the most confusing things about buying a TV is all these different terms 00:00:04.160 --> 00:00:12.080 that get thrown around. LED, LCD, plasma, CRT, the BGS. We're going to 00:00:10.240 --> 00:00:16.400 explain what all those things are as fast as possible. The most common 00:00:14.080 --> 00:00:20.320 display type these days are LCDs. That stands for liquid crystal display. It 00:00:18.240 --> 00:00:25.279 involves having a backlight, usually fluorescent, with an LCD screen in front 00:00:23.199 --> 00:00:29.519 of it. The LCD screen is where the images and the colors actually come 00:00:26.880 --> 00:00:34.559 from. One of the drawbacks of LCD is that it can never produce true blacks 00:00:32.079 --> 00:00:39.920 because that screen would have to become completely opaque or solid in order to 00:00:37.040 --> 00:00:43.600 get a true rich deep black. However, the advantages of LCD are that it's 00:00:41.760 --> 00:00:48.559 relatively inexpensive these days and unlike traditional CRT tube TVs, they 00:00:46.239 --> 00:00:52.480 are extremely thin. The next TV type, LED or light emmitting diode, is 00:00:50.719 --> 00:00:58.480 actually a bit of a misnomer because an LED TV is just an LCD TV. that is a 00:00:55.920 --> 00:01:02.480 liquid crystal display panel with an LED backlight instead of a cathode 00:01:00.800 --> 00:01:07.360 backlight. This gives it a couple of advantages. Number one is lower power 00:01:04.479 --> 00:01:11.439 consumption. Number two is even thinner form factors because they're not nearly 00:01:09.360 --> 00:01:16.159 as bulky. And number three is that with many high-end LED arrays in the back of 00:01:14.320 --> 00:01:21.119 the TV, you can actually enable a feature called micro dimming. So that is 00:01:18.240 --> 00:01:26.560 to say that the LCD goes black and the LED behind it in that zone can even turn 00:01:24.159 --> 00:01:31.680 down or turn as low as it can to make the blacks much more true and much more 00:01:28.960 --> 00:01:36.799 rich. So LED TVs tend to be just higherend LCD TVs. Plasma TVs have 00:01:34.880 --> 00:01:41.520 turned into a bit of a value option over time. They have excellent black levels 00:01:39.680 --> 00:01:45.759 because instead of relying on a backlight with a screen in front of it, 00:01:43.360 --> 00:01:50.079 the plasma display actually outputs its own light. So that means it doesn't have 00:01:48.240 --> 00:01:54.320 to output light. So very very deep blacks. You also get extremely fast 00:01:52.399 --> 00:01:59.759 response times making plasmas great for gaming. The disadvantage of plasmas is 00:01:56.880 --> 00:02:04.880 that compared to especially high-end LCD or LED type TVs, the colors can be a 00:02:02.640 --> 00:02:09.440 little bit washed out if you are in daylight or an environment where you 00:02:06.719 --> 00:02:14.319 don't have a a dark home theater to watch it on. And because the front of 00:02:11.920 --> 00:02:18.800 the display has to be glass, they tend to get a fair amount of glare, making it 00:02:16.640 --> 00:02:22.720 more difficult again if you don't have true blackness to watch your TV in. At 00:02:21.200 --> 00:02:26.319 the last minute, I decided we should include a segment on OLED. So, while 00:02:24.800 --> 00:02:31.360 it's not really available on the mass market today, OLED addresses some of the 00:02:28.640 --> 00:02:36.560 issues with LCD, such as slow response time, so much much sharper movement. 00:02:33.120 --> 00:02:38.879 It'll be great for 3D as well as the not 00:02:36.560 --> 00:02:43.840 very true to life deep blacks because OLED like plasma emits its own light 00:02:41.920 --> 00:02:49.040 rather than relying on a backlight with a panel in front of it. But it's very 00:02:47.040 --> 00:02:53.760 very expensive right now. As always guys, don't forget 00:02:51.920 --> 00:02:57.440 to subscribe to Techquie.
