1 00:00:00,240 --> 00:00:07,040 One of the most confusing things about buying a TV is all these different terms 2 00:00:04,160 --> 00:00:12,080 that get thrown around. LED, LCD, plasma, CRT, the BGS. We're going to 3 00:00:10,240 --> 00:00:16,400 explain what all those things are as fast as possible. The most common 4 00:00:14,080 --> 00:00:20,320 display type these days are LCDs. That stands for liquid crystal display. It 5 00:00:18,240 --> 00:00:25,279 involves having a backlight, usually fluorescent, with an LCD screen in front 6 00:00:23,199 --> 00:00:29,519 of it. The LCD screen is where the images and the colors actually come 7 00:00:26,880 --> 00:00:34,559 from. One of the drawbacks of LCD is that it can never produce true blacks 8 00:00:32,079 --> 00:00:39,920 because that screen would have to become completely opaque or solid in order to 9 00:00:37,040 --> 00:00:43,600 get a true rich deep black. However, the advantages of LCD are that it's 10 00:00:41,760 --> 00:00:48,559 relatively inexpensive these days and unlike traditional CRT tube TVs, they 11 00:00:46,239 --> 00:00:52,480 are extremely thin. The next TV type, LED or light emmitting diode, is 12 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 13 00:00:55,920 --> 00:01:02,480 liquid crystal display panel with an LED backlight instead of a cathode 14 00:01:00,800 --> 00:01:07,360 backlight. This gives it a couple of advantages. Number one is lower power 15 00:01:04,479 --> 00:01:11,439 consumption. Number two is even thinner form factors because they're not nearly 16 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 17 00:01:14,320 --> 00:01:21,119 the TV, you can actually enable a feature called micro dimming. So that is 18 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 19 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 20 00:01:28,960 --> 00:01:36,799 rich. So LED TVs tend to be just higherend LCD TVs. Plasma TVs have 21 00:01:34,880 --> 00:01:41,520 turned into a bit of a value option over time. They have excellent black levels 22 00:01:39,680 --> 00:01:45,759 because instead of relying on a backlight with a screen in front of it, 23 00:01:43,360 --> 00:01:50,079 the plasma display actually outputs its own light. So that means it doesn't have 24 00:01:48,240 --> 00:01:54,320 to output light. So very very deep blacks. You also get extremely fast 25 00:01:52,399 --> 00:01:59,759 response times making plasmas great for gaming. The disadvantage of plasmas is 26 00:01:56,880 --> 00:02:04,880 that compared to especially high-end LCD or LED type TVs, the colors can be a 27 00:02:02,640 --> 00:02:09,440 little bit washed out if you are in daylight or an environment where you 28 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 29 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 30 00:02:16,640 --> 00:02:22,720 more difficult again if you don't have true blackness to watch your TV in. At 31 00:02:21,200 --> 00:02:26,319 the last minute, I decided we should include a segment on OLED. So, while 32 00:02:24,800 --> 00:02:31,360 it's not really available on the mass market today, OLED addresses some of the 33 00:02:28,640 --> 00:02:36,560 issues with LCD, such as slow response time, so much much sharper movement. 34 00:02:33,120 --> 00:02:38,879 It'll be great for 3D as well as the not 35 00:02:36,560 --> 00:02:43,840 very true to life deep blacks because OLED like plasma emits its own light 36 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 37 00:02:47,040 --> 00:02:53,760 very expensive right now. As always guys, don't forget 38 00:02:51,920 --> 00:02:57,440 to subscribe to Techquie.
