Benefits of technology

[0008]There is an urgent need for moisture barrier films and edge seals for thin film, crystalline silicon solar cell modules, optoelectronic devices (e.g., LEDs, OLEDS), displays (such as plasma display panel (PDP) and Microdisplays), and vacuum insulated glass windows (VIG) and assemblies. The lifespan of

Problems solved by technology

Many conventional heating methods suffer the problem of overheating substrates in the effort to heat and flow a seal material.
Further much energy is wasted due to unwanted heating of the entire mass of substrates.
Even in all these selective heating methods unwanted heating of substrates does occur.
The process can be time consuming because such a large mass of material must be heated, w

Example

[0016]The present invention provides materials, seal designs, geometries and process steps for making hermetic seals, and simplifying the manufacture of hermetic seals which are used to protect active layers of electronic devices such as solar cells, LEDs, OLEDs, plasma display panels and the like.

[0017]A variety of substrates including those made of glass, metal, ceramic, or plastics, as well as those constituting active devices may be sealed together by this invention to create a hermetic seal in devices such as display devices (flat panel screens, LED screens, LCD screens, plasma display panels), organic light emitting diodes (OLEDs), solar cells and solar cell panels, and even windows for both architectural and automotive applications. The substrates may be coated with a coating such as conductive coated glass, indium tin oxide, aluminum doped zinc oxide, sputtered metals, antireflective coatings, SiNX coatings, Si3N4 coatings, conductive polymer coatings on glass, and combinati...

Abstract

The present invention describes a new method for creating hybrid edge seals using metal, alloy, powder coated metal and other conductive surfaces in between two substrates. The methods utilize various materials, seal designs, and geometries of hybrid seals based on polymeric powder coatings and glass powder coatings.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of Invention[0002]The invention describes a new method for creating hybrid edge seals using metal, alloy, powder coated metal and other conductive surfaces in between two substrates. These inventions describe different materials, seal designs, and geometries of hybrid seals based on polymeric powder coatings and glass powder coatings on conductive surfaces.[0003]2. Description of Related Art[0004]Many conventional heating methods suffer the problem of overheating substrates in the effort to heat and flow a seal material. Further much energy is wasted due to unwanted heating of the entire mass of substrates. Therefore, selective sealing methods wherein the seal material alone is heated are attractive from energy saving point of view.[0005]Laser sealing is a widely investigated selective sealing process, among various selective heating processes such as laser sealing, induction heating, microwave heating, broadband IR (Infrared) lamp heating, ...
