Don't be bamboozled by the tech jargon around QLED vs OLED TVs. Here's everything you need to know, simplified.

You've probably heard the terms "QLED" and "OLED" being thrown around, but what do they mean? A screen's a screen, right? Well, not exactly.

What is QLED?

QLED stands for "quantum dot light emitting diode". LEDs are an important component in common LCD screens, of which QLED screens are a variation. LEDs provide the "backlight" of LCD screens. All the other components found in an LCD screen simply manipulate this original light produced by the LED backlighting.

Where this technology, developed by Samsung, sets itself apart, is in its use of tiny "quantum dots". Quantum dots are a complicated concept, but in essence, they are extremely small particles that glow when exposed to LED backlighting.

The type and intensity of colour they produce is indelibly linked to their size, and because their size is so precisely controlled, so too can the colour of the TV be precisely controlled. Obviously the science is way, way more complicated than that, but that's the general idea.

The white backlighting of a standard LCD TV is actually a blue LED light covered in yellow phosphor, which is far from an ideal way to produce white light. In QLED models, the yellow phosphor has been discarded and replaced with a sheet of film covered in quantum dots, engineered to glow red and green.

The blue LED light, and the red and green lighting from the quantum dots then combine to produce a much better, purer white light. This has vastly improved the ability of QLED TVs to produce gorgeous-looking colour. QLED TVs also tend to be significantly cheaper than their OLED counterparts.

You'll be happy to hear the technology that goes into OLED screens is a good deal more simple.

OLED stands for "organic light-emitting diode". The first difference to note between QLED and OLED screens is that the LED in OLED actually means something different to what it does in QLED. While QLEDs rely on LED backlighting, OLEDs don't need it, as each individual pixel of an OLED TV produces its own – or self-emits – light.

Finder's resident tech expert Alex Kidman describes the benefits, in contrast to the LCD displays of QLED TVs: "OLEDs are generally held as the gold standard, as the underlying self-emitting light technology means that they offer unmatched contrast as each pixel acts as its own light source.

"OLEDs can simply switch off individual pixels (or more likely, groups of pixels) to produce a real "black", where at some level a QLED has to shutter light sources which can lead to smaller areas of blacks that are slightly grey.

"OLED also has an advantage if your viewing position isn't straight on, due again to the way it handles brightness and picture emission; QLED's backlit-led nature (even for fancier Mini-LED lit models) means that there's a more obvious picture degradation at angles to the display."

OLED technology also allows for TVs to be thinner and different shapes. Companies like LG are cooking up ideas for OLED TVs to become rollable and even stretchable. Environmentally conscious readers will be pleased to hear that OLED screens also tend to be more energy-efficient.
