INSUBCONTINENT EXCLUSIVE:
Bamboozled by TV tech terms OLED, LCD and LED Wondering why OLED is so expensive Or unsure of the benefits of LCD and LED TVs How does QLED
affect everything If you're buying a TV and have questions like these buzzing around in your head, we're here to help.Some of the
considerations to weigh up when buying a TV have changed over time: first it was smart TVs, with the challenge being to get the set with the
widest and most up-to-date selection of apps
Now, almost all TVs are equal in that regard, and voice assistants are the new hot feature to look for.Throughout those changes though,
picture quality has remained the single most important part of the TV equation
OLED, QLED, LED and LCD are competing technologies that each offer a trade-off between price and picture quality, while offering identical
color-boosting tech like HDR, HDR10+ and Dolby Vision
Then there are terms like 4K HDR Processor X1, Dynamic Range PRO and Triluminos Display (Sony), NanoCell and IPS 4K Quantum Display (LG) and
4K SUHD and Ultra HD Premium HDR 1500/2000 (Samsung) that you'll come across
mind less on all that marketing bluster and more on the important picture quality differences between OLED, QLED, LED and LCD
We'll explain everything you need to know here.[Update: Want to feel like you're helping save the world with your TV purchase Another
potential advantage of OLED screens is that their production could be cleaner from an environmental point of view
So, if you want to save the planet AND have a better picture quality, get an OLED.]OLED is a self-emissive display technologyWhat is

So smooth, fluid, colourful and contrasty are the images that it's really hard to go back to your old LCD or plasma TV
breakthrough moment for TVs
panel, organic films are placed between semiconductors, then supplied with an electrical current, which effectively means that each and
every pixel can be switched on and off individually
and extreme brightness, such as a star-filled night sky, looks realistic

brands are still selling plenty of LCD-LED TVs
LCD (liquid crystal display) and LED (light-emitting diode) TVs are often thought of as competing concepts, but they actually refer to
identical display technology
In an LCD TV, liquid crystals rotate polarized light, effectively acting as a light valve that illuminates all pixels simultaneously
Instead of the pixel-by-pixel lighting of OLED TVs, in a standard LCD TV all light comes from a big energy-guzzling backlight
basic LCD TVs of any size anymore, at least not in the original configuration
The latter is more common, largely because the resulting TV is flatter.There are a few drawbacks, namely that both techniques still get
their light from an external source that increases the components and size of the finished TV
in dark areas of the screen
That said, images are usually very bright, and very colorful, and you can buy an LED TV in virtually any size you want
they're often just tweaking old technology

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
Cue eye-popping color, but slower response times than an OLED TV
At CES 2018, Samsung announced that its QLED TVs for 2018 would use direct, local-dimming backlighting, and boast even higher brightness
If the black level performance and motion blur issues can be improved, Samsung could be on to something
OLED, QLED, LCD or LED TVMost TV brands sell whatever TV technology is popular
However, there is a schism in the market; there is no brand that sells both OLED and QLED
OLED panels are manufactured only by LG, and QLED panels only by Samsung
largely comes down to price
Want a brighter panel Go for a QLED
all seem confusing at first, but when armed with a little knowledge about the differences between OLED, QLED, LED and LCD, buying a TV isn't
quite as tricky as you might think.For a deeper look at QLED, check out our QLED vs OLED explainerCWhC46cCUQajUqzxhC96Qg.jpg#
