Abstract
A packaging structure for an OLED/PLED device. The packaging structure has a glass substrate on which a luminescent element is completed, and a sealing cap bonded to the rim of the glass substrate so as to seal the luminescent element within an airtight space. Also, a sealing agent is disposed between the rims of the sealing cap and the glass substrate, wherein the sealing agent is an alloy with a low eutectic point about 100˜300° C.
Claims18
A packaging structure of a display device comprising:
- a glass substrate, wherein a luminescent element is completed on the internal surface of the glass substrate;
- a sealing cap, wherein the rim of the internal surface of the sealing cap is bonded to the bonding rim of the internal surface of the glass substrate so as to seal the luminescent element within an airtight space;
- a first metallic adhesion layer formed on the rim of the internal surface of the sealing cap;
- a first metallic match layer formed on the first metallic adhesion layer;
- a second metallic adhesion layer formed on the rim of the internal surface of the glass substrate;
- a second metallic match layer formed on the second metallic adhesion layer;
- and
- a sealing agent disposed between the bonding rims of the sealing cap and the glass substrate, wherein the sealing agent is an alloy with a low eutectic point about 100-300° C., and the sealing agent is sandwiched between the first metallic match layer and the second metallic match layer.
