WEBVTT 00:00:00.120 --> 00:00:07.200 when researching screen types for a new TV or phone purchase or whatever 00:00:05.120 --> 00:00:11.480 figuring out which selection hits the right price to Performance ratio for 00:00:09.840 --> 00:00:16.720 one's needs can be enough to drive prospective buyers insane and apparently 00:00:14.719 --> 00:00:20.680 some companies didn't think we'd gone mad enough so they've introduced a new 00:00:19.119 --> 00:00:25.840 style which uses a little other things called Quantum dots to increase 00:00:23.359 --> 00:00:30.240 performance over standard LCDs while undoubtedly increasing standard prices 00:00:27.800 --> 00:00:34.559 as well now modern LCD screens are made up of blue LED backlights that have had 00:00:32.559 --> 00:00:38.760 a layer of yellow phosphorus added to them which causes their emitted light to 00:00:36.360 --> 00:00:43.600 turn from Blue to White this white light is then filtered through red green and 00:00:40.719 --> 00:00:48.520 blue subpixels at varying intensities creating the end color of a pixel you 00:00:46.760 --> 00:00:52.600 know whatever shade of magenta floats your boat set in an entire array of them 00:00:50.760 --> 00:00:57.800 and while this design enabled us to create a wide range of colors at pretty 00:00:54.840 --> 00:01:01.760 darn fast refresh rates the style of white backlighting that they deployed 00:00:59.440 --> 00:01:05.680 made their color Recreation especially for Reds a little bit on the weaker side 00:01:03.920 --> 00:01:11.479 and this is where the use of quantum dots in LCD screens comes in QD LCD 00:01:09.040 --> 00:01:16.360 screens also start with a blue layer of backlighting but instead of using 00:01:13.720 --> 00:01:21.000 phosphorus to turn the light white red and green fluorescent nanoc crystals are 00:01:18.840 --> 00:01:27.320 used these nanoc crystals range from about 1 and a half to a little over four 00:01:24.119 --> 00:01:29.720 nanometers in size and actually emit 00:01:27.320 --> 00:01:34.040 light instead of just filtering it so when the light of the blue LED causes 00:01:31.880 --> 00:01:39.439 the red and green dots to illuminate it creates a purer white than before this 00:01:37.079 --> 00:01:43.000 purer light is able to more efficiently pass through the subpixel filters 00:01:41.280 --> 00:01:47.759 allowing Engineers to create screens which require less operation and energy 00:01:45.000 --> 00:01:51.920 to achieve increased Spectrum ranges or in other words colors are able to be 00:01:49.680 --> 00:01:56.640 brighter and more vibrant all while the screen is using less juice but while 00:01:54.159 --> 00:02:01.079 Quantum do LCD screens boast a wider range of colors compared to their 00:01:58.560 --> 00:02:05.560 regular LED back lip predecessors that does not automatically make them the new 00:02:03.200 --> 00:02:08.959 king of the Rainbow Castle quite a few people who have seen them in action 00:02:06.920 --> 00:02:14.280 still testify to the superior image quality of OLED screens this would be 00:02:11.720 --> 00:02:19.360 largely due to their ability to shut off individual pixels creating much darker 00:02:16.400 --> 00:02:23.480 blacks and giving them this like massive contrast ratio there are also a lot of 00:02:21.760 --> 00:02:29.120 people who are questioning the ability of the initial run quantum dot screens 00:02:26.080 --> 00:02:31.440 to handle motion blur properly at higher 00:02:29.120 --> 00:02:34.720 refresh rates leading many to wonder why this technology is even being 00:02:32.760 --> 00:02:39.560 implemented in the first place the answer of course is money as if it was 00:02:37.400 --> 00:02:43.959 ever anything else like I previously explained QD LCDs operate at lower 00:02:41.840 --> 00:02:47.959 energy costs than their competitors making them highly attractive to anyone 00:02:45.760 --> 00:02:52.200 who wishes to reduce power consumption and then the other big upside to them is 00:02:49.959 --> 00:02:57.840 that the production costs of quantum LCD panels can reportedly range anywhere 00:02:54.560 --> 00:02:59.879 from as low as half to a third of an 00:02:57.840 --> 00:03:04.760 OLED screen making them extremely attractive to manufacturers as well as 00:03:02.280 --> 00:03:07.720 budget-minded consumers because the simple fact of the matter is that well 00:03:06.159 --> 00:03:12.000 there's going to be the tech Geeks out that they're like OMG they put the word 00:03:09.560 --> 00:03:16.640 Quantum in it I need seven most consumers already have screens capable 00:03:14.519 --> 00:03:20.879 of displaying content meant to be viewed at the standard of 60 HZ or below and 00:03:19.239 --> 00:03:25.680 don't generally seem to be interested in forking out huge sums of money for oleds 00:03:23.720 --> 00:03:29.840 in which they may see very minimal benefits and then if you cross-section 00:03:27.480 --> 00:03:33.480 like those guys with the people who are interested in reducing energy costs 00:03:31.599 --> 00:03:37.920 expanding battery life on mobile devices and potentially driving the purchasing 00:03:35.640 --> 00:03:43.640 cost down of their next upgrade then you arrive at this group of people that 00:03:40.879 --> 00:03:49.040 might find Quantum LCD technology very very appealing because while it's not 00:03:45.760 --> 00:03:51.519 gunning for the top dog spot with OLED 00:03:49.040 --> 00:03:56.360 as a stop Gap solution until prices fall on OLED or new technologies are 00:03:53.400 --> 00:03:59.879 developed it seems pretty compelling speaking of things that are compelling 00:03:58.079 --> 00:04:05.680 especially if you're a freelancer or small business owner fresh books it's a 00:04:02.720 --> 00:04:10.439
