PROBLEM TO BE SOLVED: To provide a method for driving an electro-optic display.SOLUTION: An electro-optic display is driven by using a plurality of different drive schemes. Waveforms of the drive schemes are selected such that an absolute value of a net impulse applied to a pixel for all homogeneous and heterogeneous irreducible loops divided by the number of transitions in the loops is less than 20% of a characteristic impulse (i.e., the average of absolute values of impulses required to drive the pixel between its two extreme optical states). The plurality of different drive schemes include grayscale drive schemes and monochrome drive schemes. 【課題】電気光学ディスプレイを駆動させる方法の提供。【解決手段】電気光学ディスプレイが、複数の異なる駆動スキームを用いて駆動される。ループ内の遷移の数によって除算された、全ての均一および不均一の既約ループの間に画素に適用される正味のインパルスの絶対値が、特性インパルス（すなわち、画素をその２つの極限の光学状態の間で駆動するために要求されるインパルスの絶対値の平均）の２０パーセント未満になるように、該駆動スキームの波形が選択される。複数の異なる駆動スキームは、グレースケール駆動スキームとモノクローム駆動スキームとを含む。【選択図】なし
