Quantum Dot (QLED) Vs OLED
四月 12, 2020

Heard of “QLED” and “OLED” but are still confused by what they mean?

Don’t worry – we have you covered.

If you’re in the market for a new TV then knowing the difference between these acronyms could very well influence your purchase. Even though the names are similar, the TV technology is quite different! We put paid to any confusion by explaining the distinctions as well as the pros and cons of each so you can make the choice for yourself as to which will suit your situation better.



In an OLED (Organic Light Emitting Diode) TV the display is made up of organic compounds that light up when fed electricity and shut down without it.

There is no chunky LCD backlight so consoles are lighter and thinner. Since light is emitted on a pixel-by-pixel basis, bright whites or coloured pixels can appear next to blacks without being impacted. Motion refresh is also supremely fast.

Pros of OLED

  • Lighter and thinner
  • More convincing blacks
  • Lightning-quick refresh rates
  • Judder and blur-free

Cons of OLED

  • Limited screen sizes
  • Muted brightness
  • Expensive
  • Higher risk of picture burn-in
  • Smaller lifespan


First there were LCD TVs, then LED TVs, now there are QLED TVs – each is a step up from the one before. What they all have in common is an LCD backlight but QLED TVs have an extra quantum dot layer (QLED stands for Quantum-dot Light Emitting Diode).

When this quantum dot layer is illuminated by the LCD backlight it delivers the highest brightness levels and the largest colour palette. Rather than millions of colours in a LED TV, we’re talking billions of shades in a QLED TV. The experience is more cinematic with vivid, precise colours and enhanced brightness.

Pros of QLED

  • More lifelike colour
  • Brilliant whites
  • Ultra-bright
  • Variety of screen sizes

Cons of QLED

  • Not as slim
  • Overly bright
  • Less convincing blacks
  • Slower refresh rate

What’s best – QLED or OLED TV?

Whether you buy a QLED or OLED TV can depend on a few factors. If you watch a lot of high action sports or movies then OLED is believed to be the superior technology. But you’ll probably pay more for it because OLED TVs tend to be on the larger size e.g. over 60 inches. So if you have a small room then a TV of this size doesn’t make much sense.

When it comes to superior picture quality then an QLED TV isn’t far behind and because this is more a mainstream TV you’ll find a wide range of sizes and prices on offer. You can get a high quality picture, superior sound and smart features, all without the high price tag. In most situations a QLED TV usually offers the best value for money.
