I strongly believe both OLED and LCD/QDs will be around for a long time to come, and they will both find their niche, until something even better comes along that we can’t resist talking about. I’m not a big fan of pinning two technologies against one another, but I do like to talk openly about the advantages and disadvantages of each. QDs took a long time to mature due to stability problems, and in a new form factor (highly concentrated in a color filter) the stability issue could crop up again. Now that’s not to say there won’t be other artifacts that show up, it’s a new technology after all and surely there will be drawbacks.
This is because every single sub-pixel is a blue OLED device, and they should all degrade at a similar rate. The burn-in problem should go away, or at least be reduced, if QD-OLED becomes a reality. you will probably be ok, but it’s still a valid fear for many consumers, and it is additional ammo that the QD camp (really any LCD) can use against OLED. So, if you avoid Sports Center, CNN, games with bright logos, static content, etc. Ok, no more political comments, I promise. “Anyone who watches that much CNN deserves to have OLED burn-in.” There is a laundry list of great comments from the peanut gallery on this, and I couldn’t help but share a few of my favorites: Or perhaps Sarah Sander’s glare went right through the feed and into the pixels. Apparently, the camera people are really good at keeping subjects centered and at similar size.
Dot by dot vs wide tv#
The funniest result? A “ghost” appears on the TV showing CNN all day long. If you watch varied content, you are probably OK.Static content burns in on OLEDs… sometimes very badly.
I think many of us could have predicted the results.
Dot by dot vs wide update#
Well lucky for us, RTings just published their one year update recently. One other notable area where OLEDs have been bashed recently is the burn-in problem (See our own Ken Werner’s deep dive with his recent blogs “How bad is the OLED-TV burn-in problem?” and “Solving the OLED burn-in problem”). However the 2018 Samsung Q#’s are not far behind, and all are higher rated than the very top OLED on the list (2017 LG C7). This technology is a hybrid cadmium-containing green QD, and non-Cd red QD, with an overall cadmium content of 1000 cd/m² for “real scene brightness” (a small white box over normal content), and only one of those contains QDs (Vizio). Interestingly, the only non-Samsung TV on the list is the Vizio P-series Quantum, which contains a QD film with Nanosys Hyperion QDs. The top seven TVs tested all contain quantum dots, and have gamut coverage of 98-100% DCI-P3 u’v’ (I rounded) and 76-83% Rec2020 u’v’. And it’s true, the colors on a QD-enabled LCD are truly breathtaking and far superior to your generic LCD.Ī quick look at the color gamut comparison on clearly shows that QD-enabled TVs win here. Since the very first QD-enabled product in 2013 (Sony’s Triluminous technology) the QD camp has been promoting wide color gamut as the main benefit of this technology.
