MATRIX-ADDRESSABLE BISTABLE DISPLAYS WITH FIELD-SPREADING LAYER AND DRIVING METHOD THEREOF

摘要

The present invention relates to a bistable matrix-addressable display element (10) comprising a substrate (15), a bistable electrically modulated imaging layer (30) having a reflection maximum, at least one conductor (20, 40), and at least one field-spreading layer (24, 32) between said bistable electrically modulated imaging layer (30) and said at least one conductor (20, 40), wherein said field-spreading layer (24, 32) has a sheet resistance (SER) of less than 10⁹ Ohms per square and a method of imaging the display comprising identifying an area to be updated of said bistable matrix-addressable display element (10), 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-addressabie display element, which may be characterized as a planar reset, left-slope selection method.
