Samsung 800x480 AMOLED
Samsung's Mobile Display group has unveiled a new display likely to improve the quality of touchscreen smartphones. The 800x480 AMOLED (active matrix organic light-emitting diode) screen has the resolution of the latest mobile LCDs but is far more color-rich, thinner and power-efficient. Despite the resolution increase, the panel actually increases brightness to 350 candelas and consumes 40 percent less power than an earlier 400x240 AMOLED display.
The technology should be useful for not only smartphones but also portable media players and other small but high-end devices. It's suggested that Samsung is already sampling the new AMOLED display but hasn't said when mass production begins.
Although AMOLEDs are already in use on Samsung phones like the Omnia HD (i8910) and Impression, they have often had to run at lower resolutions and aren't necessarily bright enough to be fully usable outdoors. Microsoft's Zune HD is one of the first mainstream portable media players to use an OLED screen.
