That's a different phenomenon. It has to do with the fact that if you display something on an LCD for a long time, the probability of the liquid crystals getting stuck goes up. You can fix it by displaying flashing black, white, and a few colors, although the worse it is the longer it takes to fix it. It's again a probability thing where the more you 'jostle' the liquid crystals the more likely they are to get 'popped out' of their stuck state.
