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.

RE: OLED finally!

blue organics currently have much shorter lifetimes (only about 1,000 hours)

The "How Stuff Works article is a bit dated...
Earlier this year, Universal Display Corp (the people developing the molecules for Samsung) created a new organic blue with a 17,500hrs @200 nits or 3,000hrs @500 nits (target luminance)...

I believe they are currently about ready to show an organic blue with a 50k hrs @200 nits molecule (rumour).

If true, that would give the OLED display a lifespan (8hrs/day) of ~3.25 years @ 500nits.
One thing to remember though, OLEDs are much less expensive to manufacture than LEDs...

That sounds like the first-gen of plasmas. Short lifespan, amazing picture and contrast. Of course now plasmas match LCDs for lifetime, so perhaps by 2010 everyone will have an OLED and LCDs, DLPs, and Plasmas will be put out at the curb.
