1. A method of writing display data to an array of interferometric display elements, said method comprising:

  • writing display data to said interferometric display elements to display an image;

    subsequent to said writing, applying a bias potential of a first polarity to a first column of the array of interferometric display elements during a first hold period;

    applying a bias potential of a second polarity to a second column of the array of interferometric display elements during the first hold period, said second polarity being opposite said first polarity;

    subsequent to said first hold period, applying a bias potential of said second polarity to said first column during a second hold period; and

    applying a bias potential of said first polarity to said second column during the second hold period,wherein said first column is adjacent said second column, wherein actuated elements in the first and second columns remain actuated during the first and second hold periods, and wherein unactuated elements in the first and second columns remain unactuated during the first and second hold periods, andwherein a transition time between bias potentials applied to the same column is less than or equal to τ

    iMoD

    RC, wherein τ

    iMoD comprises a constant of said display elements determined with reference to physical characteristics of said display elements, and wherein τ

    RC comprises a constant related to electrical characteristics of a circuit providing the bias potentials.
