I'm pretty sure that's full refresh (mode 1) and partial refresh (mode 2). From the recommendations, it says if you use partial (which looks nicer and is faster), make sure that you occasionally do a full refresh to reset the display to known values. Also, power it off whenever you can.. not only does it save power, but the higher voltage can cause permanent damage.
In my case, I'm setting up my desk clock to do a partial refresh every minute, and full refresh on the hour (like a visual "chime"). But I haven't powered it down (or put it to sleep) in 3 weeks! Guess I'd better get on that...
