QLED vs OLED

Chadd said:
Thanks guys, especially nicktay as I had not noticed that the Q8FN was different to the DN - based on price I think that is now ruled out.

With the XF90 and B8(were I to reconsider OLED), how do the Smart TV apps compare to using a separate Fire TV (not the stick, but the 4K model) connected via HDMI? Is there any benefit to the onboard versions of Netflix and Amazon Video or is it simply convenience? Thanks

had zero issues using smart on xf90 and i own a recent top of the range LG and a 4k fire tv and a panny plasma too. just get the XF90 and be done with it.

Do you know if it is actually possible to configure this on Sky? If so then I would be open to reconsidering OLEDs as this is the only issue I have. I current have a large Pause symbol burnt into the bottom left hand corner of my Panasonic Plasma which is why I had originally ruled out OLEDs.
Also, which Panasonic model specifically are you referring to please?

you're right looks like sky are delinquent .. or the oled(lg/pan/sony) itself ... why doesn't it behave like time-out/sleep on my laptop screen.

Panasonic fx750 .see earlier posts -. if viewing angle is important you have to compare in the shop to see what you can accept,
similarly, whether some FALD is worthwhile (usb stick with starry movie segment - gravity ?) rtings weighting of screen characteristics are subjective -
even though pan brightness might be less than sam/sony it is still on par with oled too.

so-called sony/pan refurb deals too, as threaded.
 
What are example videos for the current oled macro blocking problem ?

have watched some of the avforums videos supposedly for flash/block
https://youtu.be/Sc97AUImI04 and
For instance Rihanna - Kiss it better (Explicit) 4k will instantly reveal any banding issues, my B8 has it but since noy showing up on other content 95% of the time a non issue for me, clocking in at 80 hours after purchase and still within comfortable window as far as return policy concerns

... don't watch that kind of junk usually.


but don't see any blocking unlike -

for which it is very evident, but don't see how any tv avoid it on such low quality bitrates

Even though I am trying to move away from the UK to mainland Europe, I decided to take the plunge and go for the OLED65B8S, I take it with me when I move. Got it for £1594 so I couldn't say no.

I have both 4K consoles and HTPC with an Vega 64, time to put them to good use :)

presumably prices will drop with this years models arrival ... I would be looking for parity with the oled 65b8 prices so 16/1700 £ w/o the S9
although I like the Q9 don't see it worth that premium. .. how much does the sony full fald cost ?

how big a room do you need ? they need to sort out the AI upscaling though.
but, would be interesting to see the anti-reflective screen.


seems samsung are serious about entering tv oled arena.... the nanosys stuff from earlier in thread

DSCC says that production costs for a 55" QD-OLED TV panel at Samsung Display's 8.5-Gen fab will reach almost $800 in 2019. While this will fall to around $450 in 2022, Samsung will still lose money on every panel sold if DSCC has its price and cost estimates right.

Take a step back and consider why Samsung abandoned OLED tv despite success at OLED mobile phone screens and why LG managed to push on with OLED. The answer comes down to the subpixel patterning. Samsung tried to scale up the approach they use for mobile screens where a mask (fine metal mask - FMM) is used to block two thirds of the sub-pixels for evaporation of each colour. So, for example the mask blocks the red and green subpixels while the blue material is deposited and so on. The issue Samsung encountered was that while this approach worked well for mobile display substrates, when mask size was increased for tv screen sizes it became too heavy and started bowing meaning that the yields became very low. LG meanwhile pioneered their WOLED design (acquired from Kodak) where every sub-pixel (and an additional white sub-pixel) is produced from a white OLED meaning that there is no need for an FMM and this is why LG managed to quickly improve their yields and bring the costs down.

Meanwhile OLED gets many plaudits for the true black achievable meaning that this is an area Samsung is always playing catchup in. Samsung's proposed blue OLED + QDs will not solve any of the issues with OLED - as mentioned, each sub-pixel (even though they are all blue) can still age a different rates depending on content viewed which will lead to burn-in. In fact, using blue-only OLEDs will reduce device efficiency and lifetime compared to green/yellow/red OLED (although the stacked device structure will increase both, but not as much as the WOLED stack).

This is all careful marketing by Samsung who no doubt will try to pitch this technology as being superior to LG's OLED technology after they've spent the last few years trying to rubbish OLED tv and highlight burn-in issues. In reality, the main advantage will be the enhanced "colour volume' by avoiding the white sub-pixel, but this will likely lead to lower peak brightness/harsher ABL with burn-in just as much a risk.

Meh, still overpriced. I'd really not want to buy a non-hdmi 2.1 TV this year. And by that I mean having the full fat 48Gbps. Gimme that 4K 120hz 10bpc RGB goodness dammit!

I think it could work where I am now (~5m depth x ~7m width room), maybe even a bit better as I can space out from the speakers a bit more, but would have to move further back than 1.6m from the TV lol. Not that I really would, my next step-up is 75'' and that would be more than big enough since I like to sit so close to the TV for PC usage. Hell, can't complain with 55'' either.

I shudder to think about the Sammy OLED news you cited, already the LGs I looked at had a problem with blue & white combinations on screen (e.g. sky & snow) which are just horrific and a part of why I didn't buy into the OLED hype to begin with, but that may be more a problem with LG's TVs as the Sony OLEDs didn't look as bad. On the other hand, it seems to be more of an issue when requiring much more brightness from the screen than usual scenes. I really dislike colder images though, so I'm more sensitive to it.
 
Apparently the new Samsung QLEDs doing 4K this year will be capped at 4K 120 4:2:0, with only the 8K models being capable of the full fat 4K 120 RGB. Blehh.
 
so their standard hdmi chipset (their own ?) cannot support the additional RGB bandwidth;
but the uhd discsbluray discs, apart from whathisface's long time walk are 24hz 4:2:0, plus several players oppo/xbox make errors converting content to RGB,
so not really a big inconvenience ? and a gaming rig at full-rate 4K is $$$.

After originally saying no to OLED I ended up ordering the OLED55B8.

Good choice, the pause bar on sky q disappears after a minute or so and the oled dimms the screen anyway. Use the built in apps (Netflix, Amazon etc.) When they are paused a firework screensaver launches after a minute or so on my B7 I assume it's the same or similar on the 8 series.
