LG and Samsung Said to Launch Smaller Sized OLED Displays in 2022
Rumours are starting to circulate about LG and Samsung's OLED plans for 2022 and we might get a first preview come CES in January. For those hoping to get an OLED computer screen at a reasonable price it seems like you might have to wait a bit longer, unless you'd be ok with using a TV as your computer display.
LG is said to be launching a 42-inch version of its C series of OLED TVs and it should retain or improve on the features of its current C series. The model name should be OLED42C2xxx and it's expected to retail for less than the current 48-inch CX and C1 TVs. There will obviously be larger sizes available too, including the current 48-inch size, which is also said to be available in the lower cost and lower spec A2 series. As for the exact spec, we'll have to wait until CES to find out, but HDMI 2.1, HDMI-VRR and possibly either or both of AMD's FreeSync Premium Pro and Nvidia's G-Sync compatible might be part of the package.
Samsung is on the other hand said to be working on a 34-inch QD-OLED computer monitor, alongside 55 and 65-inch QD-OLED TVs. Even less is known about these products, but all the products have apparently already gone into mass production and are expected to be on display at CES. Note that QD-OLED is not the same as QLED, although both display types are using Quantum Dot technology.

Self emissive versus backlit, let's keep it straight... The quantum dot does not emit light, and the black level is not zero.

They cannot completely disable pixels. Its likely that Samsung will again produce a version of QD displays with higher black levels than anything else in OLED land to achieve the contrast ratio, which is also not 'infinite'.
But... I'll concede, technically they use an OLED 'layer' :ohwell:
Let's enjoy those gray blacks again :)
But you're right, it's not the same as their AMOLED phone displays.It's said to be per pixel.

And the problems this supposedly solves? OLED already covers the color space you need for HDR (Rec.2020), going beyond that only distorts content. And brightness? I keep mine at 60/100 in a pretty bright room. Unless you're watching TV on a beach or something, OLED is already bright enough. (Fwiw, I have a CX, C1 is supposedly already brighter.)
In short, Samsung's solution is still more complex, while solving problems no one has.
Edit: Don't get me wrong, this is way better than QLED. But it won't be better than OLED.
LG's OLEDs (WOLED) are also effectively per-pixel backlight with color filters based on Kodak's white OLED tech. Samsung is replicating the same idea of per-pixel backlight scheme with blue OLED plus quantum dot filters to get the red and blue to spectrum.Per pixel. Otherwise calling it OLED would probably prove... costly? :)Nope. Still not true RGB panel. Samsung tried that back in 2012 or so when first OLED screens were introduced. Samsung's RGB OLED TV was said to cost practically 3x more than LG's WOLED along with the problem of different subpixel aging. WOLED's downside is ~30% lost brightness due to color filters. By all indications same will apply to QD-OLED.
But I really hate it when people say OLED's black level is zero. The OLED itself can emit 0 nits, but the blackness of the panel is still dictated by the environment. Unless watching in a dark room, the black level will be whatever light the screen reflects back to you. It's still deep black and OLED will do dark shades in a way a LCD will never dream of. But 0 nits is not achieved by OLED on its own.
In other news, we have 60 Hz 3840*2160 OLED notebook panels. Where are the 240 Hz 1920*1080 OLED panels for laptops?
And the OLED panel behind it is 'always on'. Effectively a backlight. Note how even the most optimistic articles on it speak of an OLED 'layer' ;)
Therefore, your black level is going to be limited to the capability of the Quantum Dot. Therefore, Samsung cannot claim OLED black levels here.
We've seen with the Quantum Dot implementation in LCD, that it does not create true blacks.
Put simply: Samsung is still marketing its quantum dot tech as an OLED tech, blatantly lying:
BUT: that does not mean its a bad technology, don't get me wrong. Its great Samsung is doing its own R&D and it bears fruit. Its just too bad they lie so much. But in the end we might eventually have to thank Samsung, and NOT LG, for bringing OLED-like capabilities to monitors.
QD-OLED - like quantum dot infused filters - use the quantum dots' ability to convert light to red or green.No. Black level is going to be limited to what the blue OLED at the back is able to do and it is capable of turning off. It is an OLED and has black levels to match.
Asus is doing 2880x1800 on its 14-inch notebooks and they're 90Hz.
How QLED works
Quantum dot technology uses microscopic crystals that have the curious property of glowing under certain wavelengths of light, emitting their own light at certain wavelengths. They also function as semiconductors, so they can be individually turned on and off.

Now combine that info with Samsung's own picture saying there is simply a large blue LED plane behind the QD layer, and their own claim of a black level not zero, plus a contrast ratio in the hundred thousand instead of 1:millions. Let's wait and see what's really happening here .... I wouldn't be too adamant this is true OLED just yet. I could also be very wrong, I realize that. Its shrouded in the typical Samsung Mist. The same Mist where MicroLED was going to change the world and where they missed the OLED boat, while shareholders want money.
Also, if you don't turn off the backlight, the power draw will be higher than OLED.
There are 3-4 different quantum dot based technologies that Samsung is working on or looking into and which one they are talking about varies.
- Quantum Dot display that uses quantum dots directly as emissive particles. This has not really gone anywhere (yet).
- The idea I thought QD-OLED is - and it was named like this at one point - blue OLED backlight with QD filter to eventually generate a white per-pixel controllable backlight, plus color filters on top.
- Blue LED plus QD filter for backlight which seems as @bug said above - solving a problem no one has. OK, there is merit in getting backlight with clean spectrum for better color accuracy but not sure how useful that is, especially in terms of TV panels.
- QD(-infused) color filters that QLED and higher end LG's use which is pure LED-backlight LCD but better color filter.
But, and that is the key here.... the black level rises along with the peak brightness. So this puts a totally different dynamic on 'brighter OLED', because just like Samsung's QD displays on QLED, they produce rather shitty blacks at high brightness. With a true self-emitting diode, you're not blocking black, its just an 'absence of light' from the emitter.
Its good to note however that the technology will most likely end other LCD problems, slow pixel response times, backlight bleed, or visible colouration in the corners, something my current Samsung QLED TV is now well known for... its honestly the worst TV I've ever looked at/used. When I see Samsung Display... I now tend to be very careful buying into BS.
We will have to wait and see.
I stay away from anything Samsung as far as I could possibly can :D
Even tend to buy a new Tesla 4K TV rather than anything Samsung...
