  1. Nice picture, but by alhaz · · Score: 4, Insightful

    Why do i get the impression that it's bad at showing shades of blue?

    This is just like television, only you can see much further.

      Uhm, it has pure white (Red+Green+BLUE) on the screen, and the white looks white, so it's not like the blue is failing. As a prototype, maybe they had issues with getting the blue into the bottom corners of the screen, and that's why they chose the particular image that they did, but I don't think you can say there is "no discernable blue" in the image. It's just hidden in the white.

    OLEDs have a lifespan of between 10000 and 50000 hours at the moment, I think it is the blue that has the lowest lifespan. Of course, the lifespans are a lot better than they were a couple of years ago!

    Hopefully the shorter lives will be offset by the display being so much cheaper. Anyway, for computer displays most people would want to update the display after 5-7 years anyway, regardless of actual lifespan! 10000 hours is 3 years at 10 hours a day, or 6 years at 5 hours a day.

  3. Resolution by EnglishTim · · Score: 4, Insightful

    The resolution is quoted as being about 6.22 million pixels, which makes the resolution 1920x1080.

    I assume the screen is 16x9, and that the quoted pixel count is counteing each red, green and blue element as seperate.

    The point is that OLED's are not made of the same stuff that your normal "big" LEDs are made of. What they have in common is that they are diodes and emit light. Consider that the Panasonic screen has over 18 million of them packed in an area the size of my monitor. That's pretty impressive.

    What's not impressive is that they tend to grow fainter with time. The article says 10,000 hours before they lose half their brightness... that's not very long, and I'm sure you'd notice the effect well before the 10,000-hour point. Elsewhere I read that this dimming is not even across the color range, and that the images get progressively more red. LCD displays are supposed to lose half their brightness in 30,000 hours, which is not that much better imo. That makes me wonder about CRTs. My Sony 500PS is pushing 7 years and still looks beautiful. The only difference I notice is that it takes a bit longer to warm up than when it was new. Ah, trusty old CRT! As long as I keep my big desk, I probably won't even be thinking about a new monitor before 2008. I know that "degradation with time" probably makes the salespeople happy, but I know that when I'm looking to replace my monitor, I'll be looking for something that doesn't have an obsolescense plan.
