WHAT DOES QLED STAND FOR?
As always, we'll start by explaining what QLED actually stands for. In truth, it's a bit of a fudge, because the full expression its derived from is 'Quantum Dot Light Emitting Diodes'.
QDLED doesn't sound so good, though, so many have taken to dropping the 'D'. Hence, QLED.
Name-changing aside, QLED is essentially a combination of two high profile display technology principles: quantum dot and OLED. Let's break those down.
QUANTUM DOTS = HIGH BRIGHTNESS
Quantum dots are tiny particles of between two to 10 nanometres in diameter. They are employed in displays due to their ability in conjunction with other materials to give off different colours according to their size.
The advantage of this is that they're capable of emitting brighter, more vibrant, and more diverse colours, and can even approach the standard of OLED.
This makes them particularly well suited to displaying HDR (High Dynamic Range) content, which requires a high peak brightness to unleash its full potential.
OLED = TRUE BLACKS
The other half of the QLED equation is the OLED technology we've just referenced. You're probably more familiar with this than quantum dot, as it's been around for years.
If you have ever owned a Samsung Galaxy S or Samsung Galaxy Note smartphone, or have bought yourself an Apple Watch, you'll have used an OLED screen. Only LG has really been able to perfect OLED technology at TV-scale, however.
OLED stands for Organic Light Emitting Diode, in reference to an organic material it uses to light up individual pixels when a current is passed through it.
OLED + QUANTUM DOTS = TRUE BLACKS AND HIGH BRIGHTNESS
As you've hopefully worked out by now, QLED brings the benefits of both quantum dot and OLED displays together into one super-TV package.
That means a TV that boasts the improved brightness and range of colours quantum dots afford, and the clarity and deep blacks of OLED.
We must stress however, QLED isn't an OLED TV with quantum dots, but a technology that combines the benefits of both into one package.
Compared to OLED, QLED displays could boast a 30 to 40% luminance efficiency advantage, as well as consuming half the power.
Just as importantly, they promise to be much easier and cheaper to produce, without compromising on the super-thin and even flexible form factors that OLED technology has enabled.
