Thin is in, again

This week at the 2006 Korea Electronics Show, Samsung showed off a 17-inch AMOLED that was only 12mm thick -- the panel itself is only 1.8mm thick. Being one of the thinnest in the world, the display is based on organic LED technology and produces brightness and image quality to LCD displays available today. This display is able to run at 1600x1200 resolution, which is the sweet spot for many of today's larger format displays. At 17-inches however, 1600x1200 may be a bit too much for some.

Performance for the new AMOLED screen also appears to be excellent. Pixel response time is rated at an extremely fast 0.01ms. The screen has a constrat ratio of 1000:1 and a brightness rating at 400cd/m2. In terms of specifications, both constrat and brightness appear to be on par with most of today's popular LCD panels, which indicates that AMOLED technology definitely has room for maturity. Full specifications are as follows:
  • Screen size: 345.6 x 259.2mm
  • Aspect ratio: 4:3
  • Viewing angle: >170 degrees
  • Resolution: 1600 x 1200 (UXGA)
  • Pixel pitch: 216um
  • Response time: 0.01ms
  • Colors: 262,144
  • Brightness: 400cd/m2
  • Contrast ratio: 1000:1
One of the current limitations appear to be the color support of the screen, supporting only 262K colors instead of the millions of colors of today's LCDs. The other issue is that most consumers expect screens to be produced in a 16:9 or 16:10 aspect ratio these days. The 4:3 aspect ratio is definitely on the way out.

Despite a few needed improvemnts, it's clear that AMOLED technology holds a great deal of promise. Thin products are becoming the norm and TVs and displays being thin are no exception.

256K colors is all TNs right now

256K colors is no biggie for most people ...they use them day in day out with 6bit TN's and VA's and they manage via dithering to get into "16 million".

Great for Samsung pushing the envelope. Respose time of OLED/SED will finally bring CRTs to compete obsolesence....Response is critical defect LCD's have.. OLED and SED have it. Samsung really is the new Sony who just seemed to give up innovation and just make rebadged products now, hell... they don't even make monitors anymore. Can't compete.

Until the issue of native resolutions if eliminated, CRTs aren't going to completely die.

I think some of the LCD displays have the capability to switch to a non-upscaled image if the user chooses. This would mean that your screen won't be filled up, and the image could end up being too small, but at least there would be no distortion.

It's not perfect but that may be acceptable in some situations.

Well said. I was hopeful for the latest laser projectors, but as far as I could tell they're still using something like a DLP for the individual pixels. A laser projector based on scanning (like a laser printer) could, with some focus adjustment, work with arbitrary resolutions.

Mind you, any projection technology ought to handle the same, with the addition of a zoom element into the optics. I'm still waiting for someone to make a rear projector HDTV which renders both 1080 and 720 natively, by zooming and ignoring some pixels. For so long as the industry thinks digital scaling and 1366x768 is good enough (yuk) because "customers are amazed by how much better it looks than SDTV" (yes, but it's not as good as it COULD be had it not been artificially mangled) I don't hold out much hope. But that's another rant.

Let's take our display innovations where we can get them...

The thing is, you don't really care about what resolution you're running, you care if your app/os/movie doesn't look right/isn't . sized right at the native resolution. In a perfect world, all display devices would render at their native/maximum resolution, and your apps would just look crisper than at lower resolutions. Technical limitations have kept resolutions relatively low, on both the display and the renderer (video card) sides of the fence, but those limits are going away. The primative act of designing applications for a fixed resolution/dot pitch will follow soon enough.
