Know your QD-OLED from your QLED? And your mini-LED from your microLED? Good, because there’s a new display tech in town, it’s called QDEL and it might just be better than all of them.

The idea with quantum dots, thus far, has involved their ability to absorb light and then kick it back out at a very specific frequency, effectively purifying the light and also adding efficiency compared to traditional colour filters used in both OLED and LCD panels to do the same job.

But what if you could use QD materials not to absorb light from another source and re-emit it, but to be the light source itself? Then you’d have the holy grail, in other words, an emissive quantum dot display. Enter the QDEL or Quantum Dot Electro Luminescent display.

Instead of shining light on the quantum dots to activate them, QDEL does the job with electricity. So, you get all the benefits of OLED, like per-pixel lighting, perfect black levels, and extremely low response times, but without the downsides of OLED, including QD-OLED.

The most obvious of which for OLED is that it’s an organic material that wears out. But it’s also quite expensive to manufacture because it requires vacuum conditions for production. QDEL doesn’t need that and, indeed, Sharp says it can be produced in the same facilities as standard LCD panels, even using the same machinery.

That’s important because it means QDEL should be cost-effective to produce and can be scaled out to large panels, with no problem. In theory, anyway. The overall upshot, again in theory, is a new self-emissive, per-pixel panel tech with the best colour accuracy and purity of any display ever. Oh, and it won’t burn in like OLED.

From here the big question, after price, is when? Sharp demonstrated a pair of small prototype panels, one 12-inch and one 30-inch, and has no immediate plans for products you can buy.

The company was showing off the technology to potential customers at theCES 2024 event, those customers being companies that produce devices, not end users like us.

So, QDEL is not around the corner. But the overlap in manufacturing terms with plain old LCD panels does suggest we’re not a decade away from seeing the first QDEL panels in devices for sale. Digital Trends reckons QDEL panels could be made in existing LCD factories with no need to build new facilities.

It may well be that the first QDEL displays are only just a few years away. Could QDEL beat microLED to market in terms of vaguely affordable screens that PC gamers might buy? It does seem possible.

Watch this space.
