What are Quantum Dots and Do I Need Them in My TV? - Samsung Geeks

What are Quantum Dots and Do I Need Them in My TV?

| On 11, Jun 2016


The world of home entertainment is more colourful than ever with Quantum Dots. They are as cool as they sound (and look), and are the key to the next advancement in television design. Where OLED was the breakthrough TV technology a year or two ago, this year, all the major players in the TV market have vowed to make QD their latest addition, and they’re all scrambling to prove who can do it the best and the quickest.

What Are Quantum Dots?

In layman’s terms, Quantum Dots are tiny particles which measure between 2 and 10 nanometres wide. Relative to the colours of the spectrum, the smaller dots emit a blue light, while the largest emit a red. It is this nifty little trick that does away with the need for coloured filters and white LEDs.

By eliminating the broad light spectrum that has to be externally filtered, far superior colour sharpness, contrast and brightness are achieved, opening up some pretty amazing possibilities for the future of home entertainment.

What Do Quantum Dots Do?

So exactly what changes are on the horizon of QD TV technology? Well, the Quantum Dot technology is facilitating the rise of high dynamic range (HDR) TVs as a technological standard, which could usher in cinema-quality viewing in the home.

Without the need for the light to be filtered down to the appropriate hue, colour accuracy is vastly improved. The contrast between the darkest and lightest shades on the screen is greater, without glaring or dulling, producing an effect more lifelike than ever. For example, an outdoor scene would have the sharpness and glare of a summer sky, which may actually strain the eyes to look at directly, as it would in real life.

Tackling the colour inaccuracy often experienced with OLED technology, QD offers an increased colour range of between 40 and 50 per cent. The scope for such vastly improved colour gamut presents very exciting prospects for the technologies of the near future. Home viewing and gaming are now on the path to more lifelike colour and sharpness, making pioneering steps along the way.

So Are Quantum Dots Worth Having?

In a word, yes. The combination of extended colour range and improved accuracy is a winner, that is bringing TVs into a new generation. Sure, it is not a necessity, as such, but for those enthusiastic about their home cinema and gaming, and the viewing quality they get, it is definitely the latest must-have upgrade.

When Samsung are abandoning OLED entirely to focus on working Quantum Dots into their designs, you know it’s a serious winner! It’s definitely an investment, but for techies looking for the latest piece of excellence, shelling out a grand or two on a top-quality television is probably not such a consideration. Quantum Dots are making cinema-style viewing at home a reality.
