Abstract:
1. A method of controlling an electronic display having a plurality of pixels settable in a plurality of reflection levels comprising a first level, a second level and a plurality of intermediate levels, said intermediate levels forming a substantially equidistant partition of a dynamic range between the first level and the second level, the method comprising the steps of: setting the pixels in at least one preparatory intermediate level immediately prior to performing a subsequent step of setting the pixels in a desired level selectable from said plurality of reflection levels, wherein: the pixels are settable in the plurality of reflection levels by a pulse-width modulation of a voltage applicable to said pixels; a first preparatory intermediate level and a second preparatory intermediate level are provided, and each intermediate level is assigned to either the first preparatory intermediate level or the second preparatory intermediate level; and the first preparatory intermediate level and the second preparatory intermediate level are spaced from each other on a curve by one or two frame times, the curve showing reflectivity variation as a function of the time the voltage is applied.
