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.
