I guess it has to do with the crystals being no longer able to bend all
the way after a time if they are forced to do so because the pixel is
constantly active.
In contrast to a cathode ray tube where the phosphor of the pixel will
detoriate over time and get dimmer and dimmer the "burned in" LCD pixel
can be healed by quickly switching it from on to off and back for
multiple hours.
