Samsung Showcase 2004
I first reported on the SPH-i550 in my CTIA article this spring. It's the successor to the SPH-i500 Palm OS PDA-phone for Sprint. Upgrades over the previous model include a high-resolution main display, a megapixel camera with LED flash, and an industry-leading OLED outer display.
The niftiest part is the OLED display. It's divided into two parts: an upper status/icon and time/date section, which stays lit all the time - and a lower section that is full-color, and only comes on when needed. It's all one big OLED display, just with different elements on the top and bottom, similar to old-school black & white LCD phone displays that had a fixed icon row at the top.
OLED has several advantages over LCD. One is brighter colors, and this is a fine example. Colors look amazing on this. Another advantage is viewing angle. With an LCD, colors become distorted and even reversed at certain angles, and brightness is lost. OLED has no such effects, as you can see in these photos:
The outer display can be used for a viewfinder for the camera, and also for various menus and media controls, when used with the keys just below it. This gives the i550 the same convenience as a standalone MP3 player, for example.
