What Is Quantum Dot Technology & Why Is It Important?

When it comes to finding the perfect television or computer display, visual fidelity often stands out as the most important deciding factor. The only problem is, in order to create such fidelity, many modern displays make use of advanced technologies that can initially be difficult to wrap your head around.

One of the latest technological advancements making waves in the world of LED displays is that of Quantum Dots. While they may sound like a fictional element from the latest Science-fiction blockbuster, they are a very real technological marvel that can help to elevate the quality of your TV or monitor’s display output.

But what does quantum dot technology actually entail and why is it important? Dive in down below to get the latest on this emerging technology.

Put simply, quantum dot technology refers to a new form of semiconductor, designed for use in TVs and computer monitors. These semiconductors are so small, being only a few nanometers in width, that they cannot be seen with the naked eye. This naturally means that they lend themselves perfectly to generating crystal clear images on displays that they are used in.

Quantum Dot Technology not only allows for much greater visual fidelity but also allows for much richer colour values. Reds appear more intense, black values are far richer, and the whole spectrum of available colours is significantly improved!

However, the question still remains. Just how does quantum dot technology work? Let’s find out!

How Does Quantum Dot Technology Work?

The actual ‘Dots’ that make up quantum dot technology are in fact so small that they can be described as being “Zero-dimensional”. This means that they are only a few atoms in width, which makes them imperceptible to the naked eye. These dots are what allow quantum dot technology to work, and allow for high-quality images and colours to be produced.

The dots contained within the semiconductors operate in similar ways to the atoms that are naturally found in everyday objects! When the dots are subjected to an energy source, they will produce a high amount of energy. This energy is then released as light, which can vary massively in colour!

When quantum dots are employed in TVs and monitors, they are subjected to UV light, which helps them to generate energy. Whenever atoms in matter are subjected to energy, they only ever emit light that is consistent with the amount of energy that they have absorbed. This is why your kitchen table does not suddenly change colour randomly. It is always absorbing the same amount of energy.

Quantum dots, on the other hand, are specially designed to emit different wavelengths of light. This is dependent on the size of the dots that are being used, not the material that they are made from!

The dots used in quantum dot technology are specifically designed to take advantage of this fact. The dots take on numerous sizes, which in turn allows them to produce different colours. If dots are much larger, then they will produce colours that hue closer to red, as red is a colour that takes less energy to reproduce! On the other hand, smaller quantum dots will instead produce blue light. This means that the dots can move across a massive colour spectrum using only size!

What Displays Make Use Of Quantum Dot Technology?

Now that we’ve whet your appetite with the potential of quantum dot technology, you’re probably ready to grab yourself a TV or computer monitor that makes full use of it. One type of display that uses quantum dot technology, is our range of 4K QLED TVs. Let’s take a look at some of the very best displays that employ quantum dot technology.

Samsung QN90B QLED

Easily one of the best QLED TVs on the market is the Samsung QN90B QLED. If visual fidelity is what you are looking for, then you cannot go wrong with the quantum dot technology employed here. Images are displayed in their full glory across the expansive screen, and colours are far richer and more vibrant than ever before.

Many TVs struggle when it comes to replicating rich black values, thanks to an excess of light produced by the LED backlight. The QN90B makes up for this by making use of a Mini LED, which is able to produce highly specific amounts of light.

Ever watched a film on your TV, only to find that darker scenes looked unclear? This is a result of ‘Blooming’, which occurs when the display cannot replicate the darker tones, and too much light is being produced by the screen. The QN90B counteracts this thanks to the Mini LED, which produces the perfect amount of light at all times, as well as the quantum dots, which can replicate even the darkest of hues.

Samsung CHG90 144Hz Monitor

Quantum dot technology is fantastic when it comes to modern PC gaming, and that is why we absolutely must recommend the Samsung CHG90 monitor. This technology is employed to perfection here, with the monitor being able to reproduce colours with fantastic accuracy, and displaying images with clarity that is not easily rivalled.

To make the deal even sweeter, this monitor also employs a fantastic 144-hertz refresh rate, allowing for high frame rates. This means that you can always be at the top of your game when competing in online gaming.

And with all of those immense colours being replicated by this display, what better way to experience them than with an immersive ultra-wide 49-inch screen that allows you to truly dive into your favourite digital worlds?
