Methods for creating a minimally visible seal along the edge of a flat panel display

A flat panel display, comprising:

• a first display comprising a peripheral seal disposed between first and second plates of the first display along at least first and second perimeter edges of the first and second plates, and a first tape seal applied along at least a third of the perimeter edges and attached to end edges of the first and second plates;
• and
• a second display comprising a peripheral seal disposed between third and fourth plates of the second display along at least first and second perimeter edges of the third and fourth plates, and a second tape seal applied along at least a third of the perimeter edges and attached to end edges of the third and fourth plates;
• wherein the first and second displays are attached together along the third of the perimeter edges such that active image areas of the first and second displays together provide an effective larger display area that extends entirely to the third of the perimeter edges of each of the first and second displays, the first and second tape seals along the third of the perimeter edges providing a mullion between the active image areas corresponding to the thicknesses of the first and second tape seals and having a width less than one millimeter.
