Abstract
A plurality of sealing methods may be used either alone or in combination with each other to seal an electronic display structure. The display module includes a first substrate having a plurality of column electrodes. Each of a plurality of portions of a display material are coupled to one of the plurality of column electrodes and to one of a plurality of row electrodes. A pixel seal may be formed over the display material to encapsulate the display material. An area seal may be formed upon the first substrate to encapsulates the row electrodes, the column electrodes, and the portions of display material. A bead seal may be formed around the perimeter of the first substrate to couple it to a second substrate while sealing the internal display material. An edge seal may be formed by a banded structure spanning from the first substrate to the second substrate and extending around the perimeter of the substrates.
