Patent ID: 8514169

Claim:
An apparatus for displaying images, comprising: an electromechanical display element comprising at least a portion of an array of electromechanical display elements; a column driver configured to assert a voltage on one or more columns of the array; and a row driver configured to pulse one or more rows of the array with a voltage, wherein the column driver and row driver are configured to apply a plurality of potential differences across the electromechanical display element during a display write process, the column driver and row driver being configured to write display data to the electromechanical display element with a first potential difference of a first polarity during a first portion of the display write process, re-write the display data to the electromechanical display element with a second potential difference having a polarity opposite the first polarity during a second portion of the display write process, apply a third potential difference having the first polarity to the electromechanical display element during a third portion of the display write process, and apply a fourth potential difference having the opposite polarity to the electromechanical display element during a fourth portion of the display write process, wherein a state of the electromechanical display element does not change during or between the third and fourth portions of the display write process, wherein a transition time between applying the third and fourth potential differences is less than or equal to τ iMoD +τ RC , wherein τ iMoD includes a constant of said electromechanical display element determined with reference to physical characteristics of said electromechanical display element, and wherein τ RC includes a constant related to electrical characteristics of said electromechanical display element.
