If an OLED is run at full brightness with a fixed image, the image
gets burned in.  Each LED "ages" according to its use - it gets dimmer
with use.  In my case, I'm using the color that ages least, and
running it most of the time at a tiny fraction of its max brightness.

OLEDs have a nearly infinite contrast ratio - off is off, on is on.
There is no "leakage" because there just isn't any light.  LCDs leak
if the backlight is on.  Hence, OLEDs are ideal for alarm clocks,
where they're used mostly in the dark.
