Sony was showing a gaggle of 11" (diagonal) OLED displays, along with a 27" model. OLEDs, or Organic Light Emitting Diodes, were once thought to be the next big thing in flat panels. They are not only thin, but have great contrast. The light comes from the diodes themselves, and may be modulated or even shut off, similar to the way in which the venerable CRT provides its stunning contrast. The 27" model here is a full 1920x1080 resolution, while the 11" models are 1024x600.
