'Closer' is probably more accurate than 'equivalent' - I believe the gap in lifetime between the blue and the others was more than a factor of 2...

Are the blue subpixels exactly 2x larger? Also, how do you know that the lifetime vs. current or current vs. brightness relationship is exactly linear rather than exponential?

The blue looks to be about 2X larger, but you are correct - the aging effect may not be linear (in which case one way to greatly extend the lifetime of your OLED would be to watch in a dark room :-)

That's correct.

Or if the dopant is the same...
Or if the thickness is the same....
Or if the relationship (as you said) of OLED material to output in (lumen-hours?) is the same....
Or or or or or....

You're right in that we have little idea at all about this.

Java developers, when I saw what has been placed into Java 8 I was immediately reminded of how I've spent so much of my life trying to protect engineers from themselves. Lambda expressions are a horrible idea. Gentlemen: the goal isn't to make code readable for a competent mid-level engineer. The goal is to make code readable for a competent mid-level engineer exhausted and hopped up on caffeine at 3 am. What a disaster Java 8 is!

I am sorry to disagree sir. I have witnessed LCD burn in (to toast) on more than a dozen panels just in 1 airport. Far from bullet proof in the wrong application. It might be rare, but but even the beloved consumer LCD is susceptible.

I picked up a one of these sets to compare to my 950b to see what I'd like to keep. So far I'm very impressed. It has a dead pixel, anyone find there pixels came back to life?

How are you finding the UHD vs 1080 comparison between the two?

They do not come back. Is it a pixel or sub pixel? I have 2 green sub pixels, everyone seems to have a couple. A non-issue for me as you have too run a slide and to up to the screen 2 feet away to see.

There is a difference but it's not a drastic one. Although all I have to go off of is netflix 4k vs 1080p. The sony is much brighter and I notice the oled gets dimmer on whites or if I'm watching family guy. The oled holds blacks better but the 950 does a great job too. I think the color on the 950 looks better, skin tones look perfect. I have to messed with the lg setting much yet though.

Now imagine the OLED is 65" 4k and $1000 cheaper than the 950B. The one thing I do t like about Sony 4K sets is they are so darn heavy. 100 plus pounds when everything was heading lighter and thinner. Watch the Kuro demo video on you tube, should look good on both sets.

If you like baseball try watching it on the OLED it looks so Darn good. The same with soccer

When I'm sitting in the sweet spot of the 950 it's crazy how much these sets look alike.

From the photo the OLED looks much sharper. Of course your eyes will see things different than the camera.

Comparing the folds in the clothing of the passenger in the car, the panel on the left is more striking and dimensional.

You have created yourself a true pickle that only the 65" 4k OLED will get you out of.

The dead pixel that shows up on green can be seen at 9 feet back. I wonder if that's more then just a sub pixel. I'm also surprised the oled shows some banding on grey field pictures. And it also is darker on the right side near the second half on the screen.

Either you have really good eyes or yes it sound like a cluster of sub pixels. Sub pixels are so small they are hard too see and I have 20/20 vision. If you decide you like it I would exchange it. Get real close and you will see if it is a couple of sub pixels.

The only color I worry about is blue because it might theoretically be visible in a blue skyline. I think green would be impossible to see with content, but 9' is pretty far back to see it even on a slide.

I only had an issue with one set because the outer part changed the color temp so if you watched a black and whit movie the sides were a blue-red tint, I exchanged it and their set is perfect. I have ever seen any banding in content. No set will ever be perfect, you have too decide which technology your like best. If that's lcd then stick with it. I really like the 900B for the size and money but prefer OLED picture quality. I am thinking the new 10bit panels may fix the grey scale but who knows.

I had my vision checked when I was in my twenties and my vision was better then 20/20 even the doctor was impressed. I'm 31 now but I guess I still got it.

Can you clarify what you mean by "banding"? Does it show up on a photo? What is the manufacturing date of your panel?

Thanks for putting in the effort and taking the time.
Chiming in. Had the set since mid april. There are none of the issues mentioned here that bother me. The few dead pixels I have aren't visible from where I sit. I don't notice any letterbox IR. Color cast and ABL dimmed whites aren't an issue I experience in any kind of normal use, even the most "white" of content like the snowstorm episode of Fargo didn't exhibit any of these flaws - the only way I imagine being bother by them is if using the TV as a computer monitor where there will be large areas of uniform white.

Well I think I'm going to keep my 950 and return the oled. Don't get me wrong the oled is unreal set. The draw backs On the oled are the same things that bothered me with all my plasmas. If the tv was for my theater room id pick the oled for sure in a bigger size but since this is my work horse tv I like the 950 brightness and no worries of IR. In the future I can definitely see my self getting an oled.

But Barry, in terms of actual susceptibility to burn-in, we're talking utterly huge differences between LCD and plasma/OLED.

White balance of the two displays is dramatically different with the OLED looking much cooler. That alone could account for a difference in 'apparent' sharpness. I'd bet the larger display is closer to being properly calibrated.

So Adam, it's basically fear of IR & burn-in that are causing you to return the OLED? Have you seen actual evidence of either on your particular unit?

I would wait until the 65" OLED Come out. Of course 10" is a lot of screen size, to me worth the sacrifice because I could not see paying so much for the 950 when I felt the 900B has very good blacks and less issue than the 950B. I like the blacks on the 950B but the sweat spot is way to small and the blooming and other effects from the sides were far worse than the 900B.

For $8K I would go 78HU9000 or Sony 79B. I don't care about 3D and would sacrifice the black levels of the 79B for the size. With LCD I still think the 900B is by far Sony's overall best TV.
