There are rumors that Samsung is set to release a new phone called Continuum (SCH-i400). Beside the large AMOLED (probably Super-AMOLED as it might be Galaxy-S branded) it will also have a secondary OLED display just below the main. It's called the "Ticker," and it'll show weather, RSS feeds and other kinds of notifications. The Ticker will automatically turn on when you grasp the bottom of the phone. The idea is to get the information you need without turning on the large power-hungry main display.
