QLED vs OLED

viewing angles is a weird one. i have a plasma, an IPS, a VA and a TN panel in my home. none of them look bad from any angle. it's very exaggerated the difference it makes IMO.

obviously the plasma and IPS look better in fact flawless at any angle however the TN and VA the biggest difference comes from it being at the wrong height for the viewing experience. stick them at eye level and they look good even at wide viewing angles.

grey blacks is solved by FALD in fact even a lot of edge lit tv's have really good blacks. i should know as i have a panny plasma the GT50 the second last panel ever made in the plasma world the only panel better was the one used in the VT65 and ZT65.

blooming again is solved by FALD.

having owned the best in it's day (panny plasma) i now know a lot of stuff does get exaggerated in reviews. my IPS panel i had someone comment on how good the colours were. yet going off of reviews people say they are the worst tv's to buy.

if you have any mates or family that own a XF90 or superior FALD LCD, you should go and take a look. you will be surprised by how good they are and tbh IMO 99% of people wouldn't appreciate anything an OLED can do better.

I view my TV from all angles so having perfect viewing angles is a must. Plasma is pretty much perfect too, IPS is very good too (still some issues when of angle for height wise, not so much horizontally), VA much less so.

I've seen the high end FALD, they are good but only when viewing HDR content.

I came from a panny plasma and whilst the blacks are very good on those high end plasma's, OLED is in a league of its own still (and as said above, I notice the blacks even in normal lit room, heck I can even notice it on mobile phones when comparing LCD and OLED side by side.....)

I can't fault anything on my OLED, sure brightness is considered a big con but my room has lighting/glare controlled and quite frankly, I would find anything brighter than my e7 to be too overwhelming.

Like I've said before, the only time I've ever seen a high end FALD look better than OLED is when playing lesser quality content (as LCD, even FALD, masks a lot of the issues in sources such as banding, noise etc.) but feed the best quality content and that is when oled leaps ahead, in my experience anyway.
 
uled should resolve the panel related banding/dirty-screen-effect (with good matching/tight priocess control on led manufacture),
but not those attributable to the drive electronics mismatch. ?
 
It's also subjective and highly content dependent. One man's no banding might be excessive to the next. It's a minor niggle for me. I see it in the intro to First Man if anyone's watching that?
 
The one issue I have with my LG OLED is the slight banding in near black situations. I can live with that for all the plus points though. By the time I buy a 4k 65 inch upgrade, this issue should be consigned to history :)
 
The same kind of variation/banding occurs for silicon 'chip' fabrication, across one chip,
I think an analogy is with evenly baking a cake, indeed, lg replaced rtings burn-test panels due to, they said, uneven cooling after baking.

Wonder if the mastering monitors eizo/sony used in studios $30k+, roll off a different, more tightly controlled, production line,
but with the constraint of oled ~$600 55" panel manufacturing cost doubt they can eradicate banding ... like it wasn't for lcd.
... laser projection on the other hand, must be the dark viewing king. ?

I really don't think LG would be willing to give sony all there best panels and LG keep the bad ones for putting in there own TV's...;)

I don't think you were being cycnical,
but they must be able to test uniformity early on, and if Sony/Pan pay more, with consequent additional cost, through supply line,
for any returns, it would be in LG interest to bin.

Well if it was me in charge of QA on the LG panels, hardly any would get a pass lol
 
Both are very very good technology’s when set up correctly and both look outstanding, if you have a light controlled environment oled everyday of the week if you have a very bright living room then LCD/Qled

Yep, for my environment, I'd have happily gone with a Sony ZD9 over my OLED if it wasn't for the extortionate price. When you could get a new series OLED for just above a grand last year I don't know why anyone would go for an LCD other than needing a specific screen size (smaller than 55, bigger than 65) or genuine concerns with image retention for the extreme cases already covered in the thread.

It’s the same principle as when processors are produced, both intel and AMD will know what position on a wafer will produce the best chips. LG display get 8 65” and 3 77” panels from a substrate sheet so they will know through previous testing which position on the sheet will give the best panels which go to the W series and the Lowe build 9/7 and then the rest are distributed accordingly to what grade of panels other manufacturers have requested.
 
even if you are not in electronics - a very readable recent paper by LG about their oled tech
https://cdn.intechopen.com/pdfs/60365.pdf

interesting that the they characterise the TFT transistors driving the panel as having more degradation than the oled material itself,
but those exist on an lcd panel too. ?

also about generation 10 factories, for bigger oled panels and 8k challenge

Read the AVforums thread on the xf90 it's over 100 pages long. There is posts on how to get the best out of it. Plus a lot of advice given why it's the better option over oled too.

I have now got my new TV up and running and it has exceeded my expectations. It's fantastic. :D

I spent the week reading through the thread as suggested and have found great advise and couldn't be happier.

Thank you very much.;)

how can you even watch that tv? it's like a mirror i would constantly be distracted by the light and anything in the background. i even know exactly what you look like by the reflection

Amazing isn't it, you can indeed make out the poster as the blacks are so deep it's like a mirror. I guess on an LCD based screen the poster would be hidden by the Grey's.
