1. An electrophoretic display apparatus adapted to display a plurality of written character lines with at least one selected character of said written character lines blinking in a manner visible to a user of said apparatus, comprising: a fluid-tight envelope; an electrophoretic fluid contained within said envelope; a matrix of row and column electrodes passing through said envelope and said fluid, said row and column electrodes defining row and column electrode intersections; a plurality of anode segments passing through said envelope, wherein each displayed character area of said written character lines is defined by at least one of said anode segments and a corresponding group of said row and column electrode intersections; supply means for supplying individual voltages to said at least one anode segments and said corresponding group of said row and column electrode intersections to write characters to said display; control means coupled to said supply means, for controlling the magnitude, timing and duration of said individual voltages supplied by said supply means to cause written characters to remain continuously visible to said user while simultaneously causing a selected one of said written characters to blink when said control means repeatedly causes said supply means to apply a first potential bias of a given polarity between a group of row and column intersections and an associated anode segment corresponding to said selected one of said written characters, said first potential bias being applied for a duration of time which is sufficient enough to erase said selected one of said written characters and a second potential bias of a polarity opposite to said given polarity, between said group of row and column intersections and said associated anode segment for a duration of time sufficient to rewrite said selected one of said written characters.
