Abstract
A package structure and method of packaging an interferometric modulator with an integrated desiccant. An interferometric modulator is formed on a transparent substrate. A backplane is joined to the transparent substrate to form a package structure and to encapsulate the interferometric modulator. A desiccant integrated into the backplane or the transparent substrate is provided to absorb moisture within the package.
