My Samsung LED set is so black that I had to LEAVE the little annoying red "smile" LED indicator configured in so I would KNOW the set is still on. I've seen MANY times when I was playing with it's HDMI inputs and a PC....where I turned the computer off...and even in the dark of midnight....would notice I left the Sammy on. You can NOT tell its still on by looking at it if there is no signal.

And the OLED thing. I have many little "toys" that use an OLED screen....but was told VERY early on to NOT buy that little 11" TV set for EXACTLY that reason. I am in USA (San Diego)...and I do remember that set retailing for like $1600 or so. It was STILL almost a thousand LESS than any of the robots I was writing code for though (Still have one of each model of our AIBO robot). The little KIWI driving computer I have in one of the cars uses an OLED display.....and it usually stays on two bar graphs of "current" and "average" mileage. The two green bars of that graph are burned in, but it's not the same as a CRT burnin. You see it as a loss in brightness. So what I see now is the "bottom" of the two bars...are real dark now (because that area is ALWAYS lit)...and get brighter at the "higher" values that are not always lit up.

The friend who showed me his "portable Xbox" he built many years ago, we put a blank raster on the Sony OLED set to see where the color problems were coming from. A blank white raster will show ALL SORTS of what we thought were "persistancy" problems. A REAL common problem with EARLY lcd screens (which you can "excercise" out). Turns out it's exactly the opposite. Any borders and areas where numbers or stats were constantly displayed...were dark. You don't see OLED burn in when the screen is off like an old CRT. If you have ever seen an old Pac-Man arcade machine with it's original CRT...that is a PERFECT example of CRT burn-in. You'll almost ALWAYS see the "maze" on the screen if the tinted glass artwork is removed (I have an OLD Donkey Kong upright that had this with the original Sanyo monitor). A burned in OLED doesn't show this when off. It just simply doesn't light up those pixels as bright...so you see it especially in bright scenes. The Sony sets....are pretty much all losing the blue pixels faster than the rest because that "recipe" for those pixels was just not quite there for longevity. I'm not really up on the "current" state of this technology though. I do hear that some celphone displays are OLED now...but no idea WHICH ones. I assume my Pantec "Breakout" is still an LCD.
