Electrophoretic display panel apparatus and methods therefor
First Claim
1. Electrophoretic display panel apparatus comprising:
- a planar member;
a first plurality of conductive lines deposited in a first direction on said planar member, each of said first plurality of conductive lines being disposed in parallel on said planar member;
a second plurality of conductive lines disposed in a second direction on said planar member, said second direction being transverse to said first direction, each of said second plurality of conductive lines spacially crossing each of said first plurality of conductive lines to form a plurality of intersections therebetween and each of said second plurality of conductive lines including a plurality of commonly connected, parallel lines segments extending in said second direction to form a plurality of minor intersections with each of said first plurality of conductive lines at each of said plurality of intersections;
means for insulating each of said plurality of commonly connected, parallel line segments in each of said second plurality of conductive lines from each of said first plurality of conductive lines; and
means overlying said planar member and said first and second plurality of conductive lines for establishing a fluid tight panel, said means overlying creating a space above said planar member and said first and second plurality of conductive lines for maintaining an electrophoretic dispersion.

Abstract
Electrophoretic display panel apparatus having improved alignment and contrast characteristics and methods therefor is provided in accordance with the teachings of the present invention. According to a first aspect of the invention a display panel having a plurality of rows of cathodes and a plurality of perpendicularly disposed grid conductors is provided. Each grid conductor is formed as a plurality of commonly connected parallely disposed lines formed on an insulating tine structure to enable the thickness of each conductor and tine to be adjusted for optimum contrast characteristics and to ensure that the requisite number of intersections are provided between rows and columns even should slight misalignment therebetween occur. According to a second aspect of the instant invention the resulting display panel is mounted in a frame having connecting pads corresponding to similarly disposed pads associated with each column and row conductor within the panel formed to enable connection therebetween to be achieved. However, electrical connections for the conductive pads within the frame are provided through selectively actuatable delay means so that if misalignment between a column or row conductor and a corresponding pad within the frame occurs a signal applied to the connector pad within the frame may be delayed to correct any resulting misalignment.
