Quantum dots are microscopic molecules that, when hit by light, emit their own, differently colored light. In QLED TVs, the dots are contained in a film, and the light that hits them is provided by an LED backlight. That light then travels though a few other layers inside the TV, including a liquid crystal (LCD) layer, to create the picture. The light from the LED source is transmitted through the layers to the screen’s surface, which is why we say it’s “transmissive.” lg-display-booth-ces-2017-1495-001.jpgA look at the “sandwich” of layers in an LCD TV, where an LED backlight shines through a quantum dot layer (among others) and on to the LCD panel itself. Josh Miller/CNET Samsung has been using quantum dots to augment its LCD TVs since 2015, and debuted the QLED TV branding in 2017. Samsung says those quantum dots have evolved over time — that color and light output have improved, for example. In my experience however, improvements caused by better quantum dots are much less evident than those caused by other image quality factors (see below).Other TV makers also use quantum dots in LCD TVs, including TCL and Vizio, but don’t call them QLED TVs. An OLED TV is not an LCD TV at all LCD is the dominant technology in flat-panel TVs and has been for a long time. It’s cheaper than OLED, especially in larger sizes, and numerous panel makers worldwide, including LG itself, can manufacture it. LG OLEDC8P seriesOLED TVs don’t need LED backlights so, in addition to image quality benefits, they can get amazingly thin. Sarah Tew/CNET OLED is different because it doesn’t use an LED backlight to produce light. Instead, light is produced by millions of individual OLED subpixels. The pixels themselves — tiny dots that compose the image — emit light, which is why it’s called an “emissive” display technology. That difference leads to all kinds of picture quality effects, some of which favor LCD (and QLED), but most of which benefit OLED. Aside from LG, Sony also sells OLED TVs in the US, while Panasonic and Philips sell them in Europe. All use panels manufactured by LG Display, however. A closer look at MicroLED Before that we’ll get MicroLED. It’s another emissive technology, again spearheaded by Samsung, that seems closer to market than direct-view quantum dot. As you might guess from the name, it uses millions of teeny-tiny LEDs as pixels. MicroLED has the potential for the same perfect black levels as OLED, with no danger of burn-in. It can deliver higher brightness than any current display technology, wide-gamut excellent color and doesn’t suffer the viewing angle and uniformity issues of LCD. It doesn’t involve quantum dots, at least not yet, but who knows what might happen when it comes to market. QDMLED, anyone? For now, however, OLED rules the picture quality roost over QLED. At least until somebody combines the two. Originally published Feb. 8, 2017.Update, July 18, 2019: This article has been updated extensively for 2019. Now playing: Watch this: Samsung uses QLED for its best TVs, including this 8K model. Sarah Tew/CNET Two rival TV brands use very similar acronyms to describe their best TVs. But QLED and OLED are as different as leopards and lions. For the last few years Samsung, the most popular TV-maker in the world, has been branding its best TVs “QLED.” Its 2019 QLED lineup is bigger than ever, with seven series encompassing 28 different models. From insane 98-inch 8K behemoths to TVs designed to look like paintings and modern art, QLEDs represent the pinnacle of what Samsung’s formidable engineers can bring to TV buyers.  But it’s not the pinnacle of picture quality. That honor goes to OLED TVs. Based on the last few years of CNET’s side-by-side comparison reviews, LG’s OLED TVs have all delivered better overall image quality than Samsung QLED TVs. The latest example pitted Samsung’s 2018 Q9 QLED against LG’s 2019 C9 OLED and the LG OLED won handily, delivering the best picture quality I’ve ever tested. In fact the LG B8 from 2018 also beat the Samsung. The Q9 is still an excellent performer, however, and delivers the best non-OLED image I’ve ever tested — but not because of QLED technology.In June 2019 I reviewed the midrange Q70, which is an excellent performer but no OLED. I haven’t tested any of the highest-end 2019 QLED models yet, such as the Q80 and Q90, but if I was a betting man I’d still pick the best OLED to beat the best QLED TV once again this year, even though Samsung seems to have made more improvements than LG. Here’s why. A QLED TV is just an LCD TV with quantum dots Let’s start with a quick summary of the two technologies. OLED stands for “organic light emitting diode.”QLED (according to Samsung) stands for “quantum dot LED TV.”OLED is a fundamentally different technology from LCD, the major type of TV today.QLED is a variation of LED LCD, adding a quantum dot film to the LCD “sandwich.”OLED is “emissive,” meaning the pixels emit their own light.QLED, like LCD, is, in its current form, “transmissive” and relies on an LED backlight.The main takeaway is that QLED is closer to regular old LCD than it is to OLED, which I (and most other experts) consider a distinctly different class of television, much like plasma was before it. QLED vs. OLED: image quality compared Based on my reviews, here are some general comparisons I’ve made between the two.QLED TV picture quality varies more than OLED. Samsung has a bunch of QLED series, and the most expensive perform a lot better than the cheaper ones. That’s mainly because the biggest improvements in the picture quality of Samsung’s sets don’t have much to do with quantum dots. In 2019 TVs like the Q70, Q80 and Q90, they’re the result of better full-array local dimming, bright highlights and better viewing angles, which help them significantly outperform QLED TVs that lack those extras, like the Q60 in 2019.Meanwhile every OLED TV I’ve reviewed has very similar image quality — all have earned a 10/10 in picture quality in my tests. There is some variation among different OLED TVs, but they’re not nearly as significant as the differences between various QLED TV series.OLED has better contrast and black level. One of the most important image quality factors is black level, and their emissive nature means OLED TVs can turn unused pixels off completely, for literally infinite contrast. QLED/LCD TVs, even the best ones with the most effective full-array local dimming, let some light through, leading to more washed-out, grayer black levels and blooming around bright sections. QLED is brighter. The brightest QLED and LCD TVs can get brighter than any OLED model, which is a particular advantage in bright rooms and with HDR content. In my tests, however, OLED TVs can still get plenty bright for most rooms, and their superior contrast still allows them to deliver a better overall HDR image than any QLED/LCD TV I’ve tested. howwetest-tvlab-2017-cnet-11 Sarah Tew/CNET OLED has better uniformity and viewing angles. With LCD-based displays, different areas of the screen can appear brighter than others all the time, and backlight structure can also be seen in some content. Even the best LCDs also fade, lose contrast and become discolored when seen from seats other than the sweet spot directly in front of the screen. OLED TVs have almost perfectly uniform screens and maintain fidelity from all but the most extreme angles. Resolution, color, video processing and other image quality factors are basically the same. Most QLED and OLED have the same resolution, 4K, and both can achieve 8K resolution too. Neither technology has major inherent advantage in color or video processing areas. Check out OLED vs. LCD for more details. QLED can get bigger and smaller (and cheaper)There are only four sizes of OLED TV on the market today: 55-, 65-, 77- and 88-inch. Since the latter two cost $6,500 and (cough) $30,000 respectively, there’s really only two sizes most TV shoppers can afford. 35-samsung-q900Samsung’s 85-inch 8K QLED TV (above) costs $15,000.  Sarah Tew/CNET Meanwhile Samsung’s QLED TVs come in 43-, 49-, 55-, 65-, 75-, 82-, 85- and, yes, 98-inch sizes. Of course non-QLED LCD TVs can get even smaller.One big advantage, so to speak, that QLED and LCD have over OLED is the cost of mainstream sizes over 65 inches. Large televisions are the fastest-growing segment of the market and show no signs of slowing down. As I mentioned above, LG’s 77-inch OLED costs $6,500. Meanwhile Samsung’s 75-inch Q70 QLED costs $2,200 and Vizio’s 75-inch P-Series Quantum is even less. Sure, neither one can beat an OLED, but they’re still excellent performers for one-third the price.In 55- and 65-inch sizes, the highest-end, best-performing QLED models like the Q90 and the 8K resolution Q900A cost more than the cheapest OLED TV. There are numerous other, less-expensive QLED series as well, however, albeit with worse image quality.  What about OLED burn-in? Burn-in happens when a persistent part of the image onscreen — navigation buttons on a phone, or a channel logo, news ticker or a scoreboard on a TV, for example — remains as a ghostly background no matter what else appears onscreen. All OLED screens can burn-in, and from everything we know, they’re more susceptible than LCD displays, including QLED. All things considered, however, burn-in shouldn’t be a problem for most people. From all of the evidence we’ve seen, burn-in is typically caused by leaving a single, static image element, like a channel logo, onscreen for a very long time, repeatedly. That’s an issue if you keep Fox News, ESPN or MSNBC onscreen for multiple hours every day and don’t watch enough other programming, for example. But as long as you vary what’s displayed, chances are you’ll never experience burn-in.

QDVision Future outlook for OLED vs. QLED TVs Until I test the best QLED TVs against the LG C9, I won’t know for sure which one wins in 2019, but as I mentioned above, I’d bet on OLED.  For 2019 Samsung has improved its high-end QLED image quality again in an effort to beat OLED, while LG has, aside from a processing bump, mostly stood pat. The C9 wasn’t that much better than its predecessors, and I expect the same for Sony’s new OLED TVs. But given the basic differences between OLED and QLED tech, it would definitely surprise me if those 2019 QLED improvements allowed it to beat OLED overall. What about 2020 and later? Samsung is actually working on a version of QLED that does use emissive technology, much like OLED and plasma. Known as direct-view quantum dot, it dispenses with the liquid crystal layers and uses quantum dots themselves as the light source.  Emissive QLED TVs have the potential to match the absolute black levels and “infinite” contrast ratio of OLED, with better power efficiency, better color and more. That’s pretty exciting, but it’ll be a few years before we see emissive QLED TVs available for sale. Hopefully by then they’ll think up a new acronym (EQLEDs?).

3 killed in AL factional clashes

first_imgMap of NarsingdiThree people were killed and 100 others injured in a clash between two factions of Awami League over establishing supremacy in Nilakkha union of Raipura upazila in Narsingdi on Friday, reports UNB.Two of the deceased are Sohagh Miah and Maram Ali, local residents.Zakir Hasan, additional superintendent of police, said former union parishad chairman and former Raipura upazila AL vice-president Abdul Haque and present union parishad chairman and union AL president Tajul Islam had long been at loggerheads over controlling the locality.As a sequel of the previous enmity, the supporters of both the AL leaders locked into a clash around 3pm.Equipped with firearms and fishing spears (teta), they attacked each, leaving three people dead on the spot and 100 others injured.On information, police rushed in and tried to bring the situation under control.However, sporadic clashes continued till filing of this report around 8pm.The injured were taken to different hospitals, said Mohsin Alam, officer-in-charge of Raipur police station.He also said additional policemen were called in to bring the situation under control.Earlier, a Secondary School Certificate (SSC) examinee was shot dead during a clash between two AL groups at Bashgari of the upazila in the early hours.The deceased is Tofazzal Hossain Rana, son of local Abdullah Fakir.The OC said supporters of former Bashgari union parishad chairman and ex-union AL president Shahed Sarkar and current chairman Sirajul Haque, also an AL leader, attacked each other and exchanged gunfire from around 9pm till midnight on Thursday.After a short interval, they again exchanged gunfire early Friday.Tofazzel, who came out of his home to respond to the natural call, sustained bullet injuries to the head around 6am during the gunfight.Later, he died on the way to Narsingdi hospital.last_img read more

Bidi Bidi Bummed Out Fans Are Having Problems Getting A Hold Of

first_img Share Wells Dunbar/KUTH-E-B’s limited edition Selena reusable bag.UPDATE: H-E-B says it has fixed the online payment problems.Hours after going on sale, H-E-B’s commemorative reusable bags honoring Texas pop legend Selena are selling fast, but folks looking to get one online have encountered some hurdles.The reusable bags went on sale this morning at 6 a.m. for $2 at H-E-B stores or on the Texas grocer’s website. But the site isn’t processing some payments.On top of that, some are already being hocked online, going for as much as $100 on eBay.Earlier this year, H-E-B featured the Queen of Cumbia on reusable bags on a more limited run and they sold out in minutes. This time, H-E-B says, while it’s still a limited run, its stock is larger than the first-edition bags released in March.So, if you’re looking for an overpriced grocery bag featuring the Grammy-winning Texas legend, you know where to find them.Or, you could just go to a store and pick one up before they’re picked clean – as some of them already have been.*sad trombone*When 30 minutes after your Austin-area @HEB store opens is still too late to grab that awesome Selena reusable shopping bag. Now, if you’ll excuse me, I’m going to put on “Dreaming Of You”, but will actually be singing it about a grocery tote. pic.twitter.com/bV5W4Yw8GM— Amanda Gillispie (@wednesday181) December 6, 2018But, even if your location does sell out, there’s still the online option. H-E-B has insisted it’s got enough to go around this time and that it doesn’t plan on selling out as quickly. Though, it seems that the site has been inundated with orders and H-E-B says it has encountered issues with debit and credit card payments. The grocer suggests those looking to snag a Selena bag should try paying directly through PayPal.UPDATE: we are currently having payment issues with our https://t.co/0cqiwd5RPX website that we are working with PayPal to solve, and will let our customers know when it is fixed!

Trump Administration Will Keep Protected Status for Somalis

first_imgBy COLLEEN LONG and AMY FORLITI, Associated PressWASHINGTON (AP) — The Trump administration said Thursday that Somalis granted special immigration status in the U.S. can keep the designation, making them one of the few groups permitted to stay in the U.S. under a program that has allowed them to remain here for years.Somalia was first designated for the special status in 1991, following the collapse of the authoritarian Siad Barre regime, and the designation had been extended in part because nationals feared returning because of the ongoing armed conflict there. Homeland Security Secretary Kirstjen Nielsen cited the armed conflict and other extraordinary conditions in supporting the continuation of Somalia’s designation for about 500 people.(Courtesy Image/Logo)But the administration will not take on new applicants, disappointing advocacy groups.Those already with the status will be able to remain in the U.S. and will be allowed to work through March 17, 2020.Many Somalis have settled in Minnesota, which has the largest Somali population in the U.S. Community and immigration advocates have said that returning to Somalia would be a death sentence for some and that it would separate families.Democratic Minnesota Gov. Mark Dayton wrote a letter to President Donald Trump on Tuesday, urging him to extend the special status. Dayton’s letter said the conditions in Somalia are treacherous, and he pointed to a recent State Department advisory that tells people to avoid traveling to Somalia because of crime, terrorism and piracy. The advisory says those who do travel to Somalia should draft a will before traveling, name a family member to be a point of contact in the event of a hostage situation and leave a DNA sample in case it is needed to identify remains.“Under those conditions, it would be horribly ‘Un-American’ to force innocent people to return to Somalia, to break up many of their families, and to forgo their chances to live safe and decent lives,” Dayton wrote.Members of Congress, including Democratic Sens. Amy Klobuchar and Tina Smith of Minnesota, also wrote to the president, urging that the status be extended.Advocates for Somali nationals who are living in the U.S. said Thursday they are relieved that about 500 Somalis will be able to reregister to extend their protected status for 18 months, but they are disappointed the administration didn’t do more. The Minnesota chapter of the Council on American-Islamic Relations said if the administration would have redesignated the status instead of just extending it, then more than 1,000 Somali nationals could have enrolled.The International Rescue Committee and Muslim Advocates also expressed disappointment.“It is not only a mistake, it is a death sentence,” Muslim Advocates said in a statement.Around 437,000 immigrants from 10 countries have had temporary protected status, a designation created in 1990 to allow people from countries ravaged by natural disasters like earthquakes or man-made disasters like war to have a short-term safe haven.Those with it have generally been able to work and, with permission, travel outside the U.S. and return.Countries are added to the list as circumstances warrant, with renewals coming usually around every 18 months. While some countries were removed, others have stayed on for years, which critics say turns the program into default amnesty. Other countries that had the status for long periods of time — like El Salvador or Honduras — were cut off under Trump.The protections were never meant to be permanent.Under Trump, the Department of Homeland Security also ended the program for Sudan, Nicaragua, Nepal and Haiti. Several groups are suing to stay in the U.S.Protections were extended for about 1,100 Yemenis and 6,900 Syrians who already have them, but the administration has said it won’t take on new applicants.Trump has said he wants to curtail legal immigration and has been cracking down broadly on illegal immigration.___Forliti reported from Minneapolis.last_img read more

Navi Mumbai Intl Airport to be operational by 2019 Fadnavis
