Abstract
A method for sealing a liquid within a glass package and the resulting sealed glass package are described herein where the sealed glass package can be, for example, a dye solar cell, an electro-wetting display or an organic emitting light diode (OLED) display.
Claims24
A method for sealing a glass package, said method comprising the steps of:
- providing a first glass plate;
- providing a second glass plate;
- depositing a frit onto the first glass plate, where the frit forms a closed-loop on the first glass plate;
- depositing a liquid having an index of refraction that substantially matches the index of refraction of the second glass plate within a space defined by an interior side of the frit and a surface of the first glass plate, where the liquid directly contacts at least the interior side of the frit;
- placing the second glass plate on top of the frit on the first glass plate such that the liquid remains within the space defined by the interior side of the frit on the first glass plate;
- and
- using a sealing device to heat the frit such that the frit melts and forms a seal which connects the first glass plate to the second glass plate and also contains the liquid between the first glass plate and the second glass plate.
A glass package comprising:
- a first glass plate;
- and
- a second glass plate, wherein the first glass plate and the second glass plate are connected to one another by a frit which forms a seal between the first glass plate and the second glass plate and also contains a liquid between the first glass plate and the second glass plate, said liquid having an index of refraction that substantially matches the index of refraction of the second glass plate, wherein the frit is glass doped with at least one transition metal and a predetermined amount of coefficient of thermal expansion (CTE) lowering filler where the CTE lowering filler enables the liquid to penetrate the frit and be evaporated out of an interface between the frit and the second glass plate when the frit is melted to form the seal which connects the first glass plate and the second glass plate.
A sealing device that emits a light towards a glass package including a first glass plate and a second glass plate which are connected to one another by a frit, wherein the first glass plate and the second glass plate have a space between them defined by the frit in which a liquid is contained, said liquid having an index of refraction that substantially matches the index of refraction of the second glass plate, and wherein the light heats the frit in a manner where a substantially constant temperature is maintained in the frit along a sealing line while the frit melts and forms the seal which connects the first glass plate to the second glass plate and also contains the liquid between the first glass plate and the second glass plate.
