When it comes to visual content these days, everyone wants something that will be sharp, vibrant, and easy on the eyes. As you can imagine, not many display options can walk the fine line between these three requirements. 

That said, quantum dot display is starting to emerge as a possible game changer. In this article, we’ll see how it works and what makes it so unique.

What Is Quantum Dot Technology?


There’s a new star in the display game, and it’s quantum dot technology. Here, you have a display technology format that makes use of nanocrystals to control how light exhibits its properties. 

These nanocrystals are what we call quantum dots, and they exhibit quantum mechanical properties that give them their electronic and visual characteristics. 

In the sense of displays, quantum dot technology refers more to QLEDs. This stands for  “Quantum Dot Light Emitting Diode,” and it is a form of display technology that is starting to become very prominent in monitors and TV screens. 

Like many types of LEDs, QLEDs come with impressive color vibrancy and high levels of brightness. Their standard is also pretty high, and they easily stand out among most other display types. 

How Does Quantum Dot Work?

So we understand the question of “What is QLED” when it comes to displays, let’s take a look at the working principle of this display format and how it works to create the perfect output:

As we explained earlier, the QLED display format uses quantum dots to optimize the brightness and color of a display as much as possible. Fundamentally, this display comes with an LED backlight, a layer of those nanocrystals, and the primary liquid crystal display (LCD) layer. 

So, let’s take a deeper dive into quantum dot LED display and its working mechanism:

Start With The LED Backlight 

A conventional QLED display will start with an LED backlight. As we know, LEDs shine light once you pass an electric current through them. But, in the context of QLED displays, the backlight is what will give that first piece of illumination. 

Moving To The Quantum Dot Layer 

Smack in the middle of the LCD and the LED backlight, you have the quantum dots. They provide unique optical properties, all thanks to the effects of quantum confinement.

The Process Of Exciting Quantum Dots 

As soon as the white light from the LED backlight goes through the quantum dots, they enter into an excitement phase. They absorb the light coming in, then they re-emit light. 

The color of the light being emitted will depend on how large the quantum dots themselves are. Saller dots usually emit blue light, while larger ones show red light.  

Tuning Color & Expanding The Gamut

Thanks to the ability to control the size of the quantum dots, you should also be able to accurately tune the colors being emitted. And, this capability also leads to a more accurate color gamut – especially compared to some of the traditional displays that we see. 

LCD Layer Lets Light Pass Through 

Just after the quantum dot layer, you have the LCD layer. Now, this layer is what makes light pass through. The liquid crystals work like shutters, controlling light intensity and having a huge impact on the final image that you see. 

With the combination of the LCD layer and these quantum dots, you get a display that offers optimal brightness and color accuracy. QLEDs offer vibrant and very visually realistic images, so they work in different fields.

Advantages of Quantum Dot Displays

We pointed out earlier that QLEDs have become pretty popular overall – especially in recent times. And, there are several reasons for this – let’s explore the popularity factors for QLED displays:

The Colors Are As Accurate As They Are Sharp

One of the things you will appreciate about OLED displays is that they give off very sharp colors. With the use  of quantum dots, you get to control the emitted colors. And as a result, you get broader, more accurate color gamuts as well as lifelike images. 

Enjoy Full Brightness On Your Display 

As you can imagine, the benefit of optimal brightness should also be mentioned. Quantum dot displays are very bright, even when you use them in sub-optimal lighting conditions.

They Use Power Well

It’s almost a given that any LED technology will optimize energy efficiency as much as possible. And, with QLEDs, there’s no difference. They convert power into a light well, giving you that perfect balance between brightness and optimal energy consumption.  

Performance In HDR Uses

You can also make use of a quantum dot screen or a quantum dot TV for high dynamic range (HRD) content. Thanks to their improved brightness and color accuracy, QLEDs easily deliver a more realistic viewing experience across the board. 

You Can Use Them For Long 

Looking for a display option that will stand the test of time? A quantum display fits that bill. They are also very stable, so the colors you get on a quantum dot monitor will remain consistent as time goes on. 

View Them From Anywhere

The benefit of broad viewing angles means that QLEDs offer consistent image and color quality even when you’re viewing them from awkward angles. 

Choose Whichever Display Size Works For You 

Today, quantum LEDs are available in different sizes. If you want a large TV or a small screen that works with this display format, rest assured that it’s available to you. 

Burn-In Isn’t Much Of An Issue 

Unlike several other display technologies, quantum dot displays don’t have much of a risk of burn-in. They show more resistance to this issue, and this contributes to their overall lifespan. 

They Work Very Well With LCDs

We already pointed out the fact that quantum dot LEDs make use of inherent LCD technology to operate. A direct consequence of this is that you can directly integrate quantum dot LEDs into current manufacturing processes for LCD. 

QLED vs Other Top Display Technologies

Now, let’s look into a few comparisons that can give us a bit of an idea as to where QLED ranks when it comes to the best and most popular display formats. 

Is QLED Better Than 4K?

Both QLED and 4K have become incredibly popular in recent times. And, interestingly, they are also very different overall. That said, they aren’t necessarily mutually exclusive. 

You see, QLED is more related to a particular display technology. On the other hand, 4K talks more about the resolution of the display itself and how it shines and shows pictures. In most cases, a 4K LED display will come with a resolution of about 3840 x 2160 pixels.

With this definition, you can see that there’s not much of a basis to compare QLED and 4K. Both terminologies refer to different things, so you don’t want to get confused. 

In general, it’s pretty common for you to find displays that combine the QLED display technology and the 4K resolution. Essentially, it means that a quantum dot TV or a quantum dot monitor can indeed have a resolution of 4K, thus getting the best of both worlds – the enhanced color from QLED, as well as the heightened pixel density that 4K provides. 

As we all know, there are several critical things you want to consider when looking into a display – from the display technology to the resolution and much more. By getting the best of all, you can create a much better viewing experience that everyone will love. Today, QLED and 4K provide the pinnacle of their respective departments. A display that combines both will be able to produce vibrant colors while also getting very clear content. 

That said, you need to also keep an eye on your budget here. Both QLED and 4K are high-end technologies, and anything that will co, bine both will come at a pretty hefty price. Still, remember – the price shouldn’t be your only priority here. As long as you get the right image quality and resolution, you’re good to go.

QLED vs OLED: What’s The Difference? 

There might not be a basis for comparing QLED and 4K, but there definitely is a basis for pitting QLED and Organic Light Emitting Diode (OLED) against each other. Both are very distinct and as you can imagine, they differ on several fronts. 

What Powers These Display Technologies?

We already explained how QLED works – quantum dots are placed within the LED backlight for an LCD, and they work that way. With OLEDs, though, we use organic compounds to show light as soon as electricity is passed through. Each pixel in an OLED emits light, so you can control individual pixels on your own. 

Which Option Is Brighter? 

Both options do well when it comes to brightness and color accuracy. They are vibrant and sharp, but QLEDs tend to take advantage of them. They get higher peak brightness levels, so if brightness is really what you want to focus on, it should probably be your pick. 

Comparing Their Contrast Ratios 

Here, OLEDs come out ahead. Don’t get us wrong – the contrast ratio readings for QLED are pretty impressive. But, compared to OLEDs, they don’t quite measure up. Because QLEDs still need backlights to work, there’s always a risk of some light leaking through when you’re trying to show black. 

Where Can You View Them From?

The viewing angles available in both options are pretty broad. You can sit at awkward angles and still get proper views of the content, and this means that they both are at a stalemate when it comes to this comparison point. 

Are They Thin To Look At?

In terms of the thin form factor, OLEDs win. QLED screens are quite thin, but the fact that they use an added LCD component means that they’re not quite as slim as OLEDs. 

At the same time, OLEDs work better when you’re trying to create flexible, curved displays. Manufacturers already use them for these so that’s a point for them. 

Concerns Over Gradual Burn-In

Burn-in occurs when you have static images over time. Over a period, burn-in will lead to uneven wear on your display, and it can affect the quality of what you’re showing. With QLEDs, you barely have a concern with this. On the other hand, OLEDs are a bit susceptible to burn-in. 

How Much Are They? 

Everyone cares about the financial component when considering display options, and they absolutely should. If this is your top priority with choosing a display, then you should probably go for QLEDs. They tend to be more affordable than OLEDs, they’re popular among budget-conscious consumers.

Are QLED Monitors Good For Gaming? 

Gamers, assemble!

If you’ve been looking for a display option that can help you supercharge your gaming experience, then the quantum dot display should be at the top of your list. Easily the biggest benefit they offer is the improved color vibrancy, which allows you to enjoy lifelike visuals regardless of the game you play. 

With optimal brightness, QLED screens ensure that you can enjoy clear visibility regardless of the playing conditions. They also come with quick response times, cutting down on motion blur and ensuring that you can enjoy fast-paced gaming. 

Then, there’s the fact that some QLED monitors support adaptive sync technologies like AMD FreeSync and NVIDIA G-Sync. These technologies help ensure that you never have to worry about stuttering and screen tearing, and they help to ensure perfect sync between the motion’s refresh rate and the frame rate of your graphics card. 

With all of this – as well as benefits such as HDR support, large display sizes, and high refresh rates – it doesn’t matter what game you’re playing. You can rest assured that a QLED screen will work for it. 


QLED displays have become a mainstay. They might not be the most ubiquitous, but the benefits they provide show that they’re on the way to dominating the entire display space.
