Abstract
Abstract A flat-panel display is constructed by sealing a metal flange to a frame on a glass pane, then mounting an electrode structure against the pane within the frame, then placing an impervious malleable sheet over the electrode structure, then sealing the sheet to the flange, and then pumping air from the space between the sheet and the glass pane, and backfilling as required.
