I consider every video I put out fromCES 2025included some descriptor of this question : Any news show on QDEL ?

To be fair , in the CES preview video , I did tease that I had news about QDEL . However , you ’ll notice I ’ve been silent about it . There ’s a account behind that , and I ’m felicitous to report that the story ends with QDEL having made far more onward motion than require .

Should we still be excited ? Between the advancements we saw in OLED panel and mini - lead backlighting engineering , does QDEL still have its own chapter in the annals of display forward motion , or will it finish up being a footer ?

First , let ’s do a straightaway QDEL taking into custody - up .

What is QDEL anyway?

QDEL is another annoying tech acronym that endure for Quantum Dot Electroluminescent . In practical terms , it ’s a display made up of quantum acid that make light when electrical energy is apply to them .

When you hear about quantum Elvis in your TV , they are typically tiny nanoparticles that radiate a certain color when you shine light on them . They radiate empathetically . That ’s what ’s happening in aQD - OLED : drear OLED lights radiate on quantum point that beam ruddy or light-green in reply to that blue light — and thus you have an RGB display .

In an LCD presentation like an LED or mini - direct backlight TV , the quantum superman help make very bright , near - staring white lighter , which expands the semblance gamut and color intensity of those video . Again , the quantum dots are help — they do n’t make their own light .

In a QDEL display , or Nano - LED , the quantum Zen nanoparticles make their own Inner Light . In many ways , a QDEL showing has all the benefit of an OLED showing , but with none of the drawbacks ( or at least that ’s the dream ): arrant Shirley Temple , exacting color , high colouration brightness , and crying pixel reaction clock time — all without the peril of burn - in and with a much longer lifespan than OLED .

The display swot residential area ( of which I am a proud add-in - carry member ) has been looking forwards to QDEL since the tech was floated as a hypothesis . However it was n’t untillast year at CES 2024that the public ever saw it in action , and that ’s because I got let into a backroom at the last bit to see a prototype that was not being show to the public .

Naturally , folks have been eager to see and hear if any developments had been made . And I was afraid I ’d have to partake in some disappointing news .

Ahead of the show , I spoke to one of my beginning who tell that there had been major onward motion with QDEL displays and that there were three panel manufacturers working on them . But , despite contact out and assuring those reference I would do a good problem account about it , they remained skittish . These display manufacturing companies do n’t have the atomic number 59 and marketing blazonry like the consumer electronics company ( that I consider with ) do . They are n’t concerned in showing to consumer . or else , they want to get electronics companies to buy their stuff , and only when it is quick .

And there it was …

At first I thought I would have to report that there was progress on QDEL but nobody would show it to me . Then , at the last potential second , I found out that there was a QDEL presentation on the show floor — aright smack in the midriff of Central Hall at the Las Vegas Convention Center , veil in unembellished sight .

Because CES is so monolithic and ethnic music are busy gawking at gigantic TVs and robot vacuums , it seemed nobody had watch it , include me . But , after being tippytoe off , I sent someone there to shoot video of it : a QDEL display at oeuvre in a 14 - inch laptop computer , tucked away in a far box of TCL CSOT ’s display within the much declamatory — and , frankly , distracting — TCL electronics booth .

I call up that CRT screen looks pretty honorable , specially compare to the super - early prototype we saw last year . For indisputable , we are several steps closer to see a television receiver - sized QDEL screen epitome . Once that happens , a QDEL TV could be mightily around the quoin .

Setting aside the hullabaloo over seeing something newfangled and groundbreaking , we do need to take some hardheaded questions . We saw both WOLED andQD - OLEDpanels make another grown jump in brightness at CES this year : up to 3,700 nit peak from a young four - layer OLED exhibit ( that we cansafely assume comes from LG Displayand could hit 4,000 nit in the new G5 ) as implemented in Panasonic ’s upcomingZ95B TVand a new 4,000 - nit peak , 400 - nit full screenland QD - OLED from Samsung Display . So , the first question is : Do we still ask QDEL ?

I would indicate yes , we do .

OLED-like performance, but for less

As awesome as OLED is and is becoming , it ’s still based on organic chemical compound , which have in mind there is some lingering burn mark - in risk and there is a jolly limited aliveness - couplet . Honestly , those are n’t material upshot for most citizenry . The real issue for most telecasting buyers is the damage ticket . OLED TVs are expensive to make — the OLED manufacture mental process is regard and costly , and that has n’t changed much over the past few yr . Most significantly perhaps , large - screenOLED TVsare prohibitively expensive . Meanwhile , 98 - column inch LCD TVs are going for as small as $ 1,500 on sale .

What QDEL means for the futurity is OLED - same operation — in some measuring better than OLED — with no burn - in risk , a much foresighted lifetime , and the ability to perform well in extreme heat and stale , and ( the least aphrodisiac , but arguably most crucial broker ) it ’s not very expensive to make .

You may have heard about some new approaches to using quantum dot , like ultraviolet micro - take excited quantum dots . The concept of that technology is passing intriguing , but there ’s a lot to iron out out , too . Micro - moderate printing proficiency may see some big improvements in coming years , but something tell me QDEL could come to market a little earlier than anything with micro - LED attached to its name .

Yes , QDEL is very relevant and remains very exciting . If there ’s any display technology that could unseat LCD ’s control in the goggle box space , I recall it ’s QDEL .

I be after on visiting the Display Week conference in May . There I believe we ’ll see more about QDEL , and we might get even more data on its progress . Stay tuned .
