QLED (according to Samsung) stands for "quantum dot LED TV." ... 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.
QLED comes out on top on paper, delivering a higher brightness, longer lifespan, larger screen sizes, and lower price tags. OLED, on the other hand, has a better viewing angle, deeper black levels, uses less power, and might be better for your health.
QLED panels are not self-emissive, instead lit by LEDs along the edge (just like an Edge LED-backlit LCD). The advantages of QLED TVs are that they use a quantum dot color filter and are capable of significantly higher brightness than OLED TVs. ... But only if they're cheaper than OLED, which for now remains the benchmark.
In looking at standard 4K LED TVs vs 4K OLED TVs, both offer great viewing experiences and improvements over 1080p. But LG OLED technology will truly transform your home entertainment experience with superior blacks, cinematic colors and High Dynamic Range with Dolby Vision support.
Generally speaking, if you're in the market for a TV, Samsung's QLED TVs are a good choice, and provide decent value for the money.
OLEDs are made by a different process: OLED which is currently limited to 400mm x 500mm in size in the merchant-fab world. TV-sized panels are specially made, which make them expensive.
It's easier and much less expensive. But both LG and Samsung have developed their smart TVs from scratch. ... LG manufactures OLED displays, which are considered to be the best in terms of color and contrast. Samsung still uses QLED technology, which can't quite match OLED for picture quality.
The LG CX is the best OLED TV that we've tested. It's part of LG's 2020 lineup and is available in a wide range of sizes, from 48 to 77 inches; we also tested the 48 inch model as a monitor. It offers the best performance for its value compared to other OLEDs, even if they have similar picture quality.
There's no doubt that QLED, for now, has an advantage in terms of brightness (so in theory may better handle HDR content – though might just as easily overcook it), but if you're looking for a 'paradigm shift' in picture quality and the next-gen display technology, OLED is still the frontrunner.
Best picture and sound: Sony Bravia A8H OLED
The Sony Bravia A8H OLED is our top pick when flawless picture and sound are what you want. With top-notch color, incredibly crisp detail and the latest (and best) version of Android TV we've ever seen, there's a lot to love about the new Sony OLED.
Absolutely. If you can afford it of course. There's no type of TV with the same contrast, black levels and viewing angles.
What's the lifespan of an OLED TV? Any OLED TV should last you years of use. Back in 2016 The Korea Times reported that LG OLED TVs had a lifespan of over 100,000 hours (11 years of constant use).
