Abstract
An electronic display screen is created by processing a mirror on a substrate glass. A back plate glass is then placed on top of the substrate glass and sealed to the back plate glass. A hermetic seal that includes an adhesive mixed with zeolites is disclosed. The hermetic seal can seal the back plate glass with the substrate glass. The application of the hermetic seal is not limited to the electronic display screen. Rather, the hermetic seal can be used to seal a variety of surfaces including metals, polymers, plastics, alloys, ceramics and the like.
Claims13
A micro-electromechanical systems based device package comprising:
- a back plate glass;
- a substrate glass;
- a bead of an adhesive mixed with a zeolite applied between the back plate glass and the substrate glass;
- and
- a mirror processed on the substrate glass.
A micro-electromechanical systems based device package comprising:
- a back plate glass;
- a substrate glass;
- and
- a bead of an adhesive mixed with zeolites of different pore sizes applied between the back plate glass and the substrate glass, wherein the zeolites of different pore sizes are selected to absorb molecules of different diameters.
A micro-electromechanical systems based device package comprising:
- a back plate glass;
- a substrate glass;
- and
- a bead of an adhesive mixed with a zeolite applied between the back plate glass and the substrate glass, wherein the zeolite is selected to have a pore size which allows the zeolite to absorb a contaminant gas that is outgassed by components of the package, and wherein said pore size is up to fifty Angstroms.
