Abstract:
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; applying a first bias potential having said first polarity to said MEMS display element during a second portion of said display write process; and applying a second bias potential having a polarity opposite said first polarity to said MEMS display element during a third portion of said display write process, there being a period of time between said applying said first bias potential and said applying said second bias potential, wherein a transition time between said applying said first bias potential and said applying said second bias potential is configured such that a state change of said MEMS display element will be avoided when a voltage having a value outside of a hysteresis window of said MEMS display element is applied across said MEMS display element during said period, wherein the transition time between the first and second bias potentials is less than or equal to τ
