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.
Claims32
A display device, comprising:
- a transparent substrate;
- an interferometric modulator configured to modulate light transmitted through the transparent substrate;
- and
- a backplane cover disposed on the modulator and sealing the modulator within a package between said transparent substrate and the backplane cover, wherein the backplane cover has an integrated desiccant configured to absorb moisture within the package.
A method of manufacturing a display device, comprising:
- providing a transparent substrate;
- forming an interferometric modulator on the transparent substrate;
- joining a backplane to the transparent substrate to form a package, wherein the package encapsulates the interferometric modulator;
- and
- providing within the package a desiccant contained within a membrane.
A display device, comprising:
- a package comprising a transparent substrate, a backplane, and a seal applied between the backplane and the transparent substrate;
- an electronic display configured to modulate light transmitted through the transparent substrate, wherein the electronic display is formed on the transparent substrate and positioned between the transparent substrate and the backplane;
- and
- a desiccant contained within a pouch adhered inside the package, wherein the desiccant is configured to absorb moisture within the package.
A display device, comprising:
- a transmitting means for transmitting light therethrough;
- a modulating means configured to modulating light transmitted through the transmitting means, wherein the modulating means comprises an interferometric modulator;
- an encapsulating means for sealing the modulating means within a package between the transmitting means and the encapsulating means;
- and
- a moisture absorbing means integrated into either the transmitting means or the encapsulating means, the moisture absorbing means configured to absorb moisture within the package.
A display device, comprising:
- a transparent substrate;
- an electronic display configured to modulate light transmitted through the transparent substrate, wherein the electronic display is formed on the transparent substrate;
- a backplane joined to the transparent substrate to form a package, wherein the electronic display is positioned between the backplane and the transparent substrate;
- and
- a desiccant within at least one pouch in the package, the desiccant being configured to absorb moisture within the package.
A method of manufacturing a backplane, comprising:
- providing a backplane having a recessed area on a surface, wherein the recessed area is created by applying a mask to the surface of the backplane and etching an area of the backplane exposed by the mask;
- and
- applying desiccant to the recessed area on the interior surface while the mask is on the surface.
The method of Claim, 29, further comprising:
- providing a transparent substrate having an interferometric modulator formed thereon;
- and
- joining the backplane to the transparent substrate to form a package after applying the desiccant, wherein the surface is an interior surface of the backplane.
