ABSTRACT:
The present invention relates to a bistable matrix-addressable display element comprising a substrate, a bistable electrically modulated imaging layer having a reflection maximum, at least one conductor, and at least one field-spreading layer between said bistable electrically modulated imaging layer and said at least one conductor, wherein said field-spreading layer has a sheet resistance (SER) of less than 109Ohms per square and a method of imaging the display comprising identifying an area to be updated of said bistable matrix-addressable display element, wherein said area to be updated comprises rows of pixels; and applying a sequence of drive signals having a 4-phase approach to image said bistable matrix-addressable display element, which may be characterized as a planar reset, left-slope selection method.
