| 1. A method of actuating a MEMS display element, said MEMS display element comprising a portion of an array of MEMS display
elements, said method comprising:
writing display data to said MEMS display element with a potential difference of a first polarity during a first portion of
a display write process;
re-writing said display data to said MEMS display element with a potential difference having a polarity opposite said first
polarity during a second portion of said display write process;
applying a first bias potential having said first polarity to said MEMS display element during a third portion of said display
write process; and
applying a second bias potential having said opposite polarity to said MEMS display element during a fourth portion of said
display write process,
wherein a state of said MEMS display element does not change during said third and fourth portions.
