You’ve seen the term QLED everywhere in TV stores and online sites, but what does it mean? QLED stands for Quantum Dot Light-Emitting Diode. Simply put, this means that a QLED TV is the same as a regular LED TV. But the difference is that it has a quantum dot layer that, like color and brightness, enhances what you see.

You usually don’t even have to read what each technical term means. But QLED is an important one because (if you haven’t already) you’ll see it again and again if you’re looking for a new TV—especially if you’re eyeing one. new samsung tv.

The important thing you need to know about QLED is that it is a type of LCD panel technology. The quantum dot layer within the panel that sets it apart from the rest looks exciting. But it’s basically a difference of degree, rather than type, from most other TVs you can buy.


However, it is not the same You – Despite sounding very similar. we have a perfect OLED vs. QLED Guide that gives you a detailed account of the main differences between the two if you’re struggling to figure out which one is the right choice for you.

Now that the basics are over, the most important thing you need to know about QLED – something that’s rare in TV technology – is that it’s a panel technology developed for most people. . best samsung tv.

However, confusingly, you’ll find something else TV brand Use QLED labels – not too many of them. This includes TCL and Hisense. However, as a general rule, most QLED TVs you’ll find in bricks and mortar stores or online retailers will be made and sold exclusively by Samsung.

You’ll find this QLED panel technology packed into some of Samsung’s latest and greatest 8K TVhandjob also, including Samsung Q800T And this Q950TS. However, most of the QLEDs available in the market today are still 4K TV.

Now you’re ready to get up to speed with the QLED on the Surface, how does it work? How will it enhance your entertainment experience? And, importantly, is it worth investing in a QLED TV? We know it’s hard to find TV tech advancements unless you’re really looking for them, but hopefully the guide below helps you understand what’s what.

Read on to learn everything you need to know about QLED technology, including how it differs from other panel types, and whether it’s really the right choice for you.

What is QLED?

QLED is an acronym which means Quantum Dot Light Emitting Diode. It should not be confused with OLED, which refers to an organic light-emitting diode, and is a competing display technology that we will not go into detail here.

But wait, what is a quantum dot light-emitting diode – or QLED – display? And how does it compare to a regular LCD television?

The QLED is, for the most part, a Samsung concept that’s basically the latest set of enhancements to the same quantum dot technology that the company has been working on for the past few years.

To get technical – and to add some confusion – Samsung’s range of QLED TVs isn’t QLED at all. Well, at least not in the way we understand the term. A ‘proper’ quantum light emitting diode element emits its own light – the clue is in the name.

However, Samsung’s latest TVs use a separate LCD backlight (often an edge-lit backlight) like any other LED-LCD TV. So the QLED moniker for TV panel technology is really more about branding than a ‘quantum leap’.

But there’s still a lot to be excited about here. QLED TVs use metallic quantum dot filters to enhance both the color and contrast of the screen. This means that the capability of HDR and 4K images is significantly increased compared to other non-quantum dot LCD-LEDs.

QLED TV models include Samsung’s Bixby virtual assistant as well as an Ambient Mode, which helps them blend into their surroundings a little better.

What about ‘Neo QLED’?

In 2021, Samsung changed its QLED branding to ‘Neo QLED’ to make significant changes to its QLED range. The key difference is the introduction of a MiniLED backlight, packing ten times the normal amount of LEDs for brighter brightness, wider viewing angles and less bloom – ensuring that light is directed only where it should be.

Result? 100% color volume of DCI-P3, plus better local dimming.

When asked what specs the Neo QLED will change, Dan Shinasi, director of product planning at Samsung, said, “Yes for HDMI 2.1. Yes 4K at 120Hz. Yes for VRR. Yes for FreeSync Premium… Yes to everything.”

What is QD-OLED?

A new report from Korea IT News (via CNET) claims that Samsung may be making the move to OLED – or at least one kind of OLED – as soon as next year. Does this mean that the brand is eliminating QLED? off course not.

The report builds on years of rumors that Samsung was developing a ‘QD-OLED’ hybrid screen, which combines an OLED TV panel with the quantum dot technology that underpins Samsung’s popular QLED range.

The QD-OLED is said to use a self-emitting OLED panel to emit blue light, as well as a quantum dot filter to convert this light into other colors – bypassing the need for a backlight , because the OLED panel acts as its own light sources. , but still using QLED technology to increase the contrast. The exact effect, or level of picture quality, however, has yet to be seen, but is expected to allow for higher brightness and an even wider color gamut than traditional OLED.

There’s no official model or public timeline for Samsung to debut the technology, but the report matches what was said by market analysts last year – with Omdia predicting a mass release for Samsung’s QD-OLED sets. Production will begin in late 2021 for a 2022 release.

How does QLED TV work?

All QLED TVs have a quantum dot filter. It is a film of tiny crystal semi-conductor particles that can be precisely controlled for their color output. They replace the red, green, and blue filters commonly used in older TVs.

This filter now also uses an aluminum compound to help the dots be more efficient (and therefore brighter) and more effective at passing light, which creates wider and more accurate colors.

Samsung says its QLED TVs use new filters to display 100% coverage of the DCI/P3 color space (read: very deep black levels and sparkling HDR), and maintain that display whatever the brightness.

In fact, they’re so bright that Samsung’s QLED TVs can manage 4000 nits of peak brightness on their most premium sets. Considering the 1000 nits needed to produce HDR, it’s very bright, and far above the sub-1000 nit levels found on OLED TVs.

New advances in Pixel panel composition also mean that 2019 models and later are far better for off-axis viewing. For the living room environment, this could be the big selling point of the QLED.

Beyond the ‘paradigm shift’ exaggeration of Samsung’s marketing, it’s really important to understand that QLED is really nothing new. In fact, it’s really nothing more than the latest — possibly the last technically possible — of the current LED-LCD technology that has dominated big-screen TVs for the past decade.

QLED’s innovations – deeper blacks, better colors and wider viewing angles – tackle three traditional problems of LED and LCD technology, but these are the same problems that are addressed year after year by TV makers. Only upcoming reviews will reveal whether QLED is really a significant step up from traditional LED-LCD screens – but chances are good we’ll see some real improvements in these areas with Samsung’s new sets.

Can QLED replace OLED?

perhaps a more important comparison is QLED vs OLED. The latter uses pixels that emit their own light, but OLED displays are only manufactured by Samsung’s arch-rival LG, and are now used Sonyhandjob PHILIPS And Panasonic, very.

There’s no doubt that QLED, for now, has an advantage in terms of brightness (so can in theory handle HDR content better – though it can easily be overcooked), but if you’re looking for a picture Looking for a ‘paradigm change’ in quality and next generation display technology, OLED is still at the forefront. The latter uses individually lit pixels to achieve superior contrast ratio and rich blacks that the LED-LCD will never be able to hit, quantum dot filter or not.

Samsung’s new Neo QLED range may balance the scales a bit with better brightness controls and viewing angles, but we’ll have to wait until we can fully test the set to say for sure.
