Abstract
Abstract Overlaid alignment and mounting of a series of grid electrodes in spaced apart relation to a plurality of corresponding indicia electrodes on a substrate member of a display device is provided. A grid retaining member includes a series of grids retained by common opposing sides of a flex removable frame. Depression channels are provided at the retained ends of the grids whereby mounting pads are provided for accurately spacing grid and indicia surface portions, and whereby the various ones of the series of grids may be secured to corresponding ones of a series of terminal pads on the substrate. Protrusions from a base carrier member engage the peripheral walls of the various other members to provide alignment of grid surface portions with corresponding ones of the indicia electrodes. A method is described in which the members are internested in overlaid sequence above the base carrier member whereby fixed spaced-apart alignment of the grid and indicia surfaces is accomplished and whereby contact between various corresponding ones of the mounting and terminal pads is achieved. The respective grid mounting pads are then secured to corresponding ones of the terminal pads along the substrate member. The opposing side portions of the frame are thereafter flexibly broken away to provide electrical isolation of the grid electrodes.
