Sony showed off some new OLED displays at the Display 2007 Expo trade show. The first is capable of 1080p resolution and sports a 1,000,000:1 contrast ratio. But more impressive is the fact that it only measures 9mm in thickness. A second model, measuring only 3mm in thickness, is capable of a resolution of 1,024 x 600 pixels.
OLED (organic light-emitting diode) technology consumes less power than comparable LCD displays. One reason for this is that they do not require a backlight. While theoretically cheaper to manufacture, they are not without their drawbacks. Among those is the limited lifetime of the organic materials.
OLED definitely bears watching.
