Abstract
Disclosed is an organic light-emitting display device capable of blocking the infiltration of oxygen and moisture, etc. by encapsulating an array of pixels by interconnecting first and second substrates with a frit. The organic light-emitting display device includes a first substrate, a second substrate opposing the first substrate, an array of pixels interposed between the first and second substrates, and a frit positioned between the first and the second substrate to adhere the first substrate to the second substrate. The frit is formed to overlap with at least a part of scan drivers.
Claims20
An organic light emitting display device comprising:
- a first substrate;
- a second substrate opposing the first substrate;
- an array of organic light emitting pixels interposed between the first and second substrates;
- a scan driver interposed between the first substrate and the second substrate;
- and
- a frit seal comprising a plurality of elongated segments interposed between the first and the second substrates, the plurality of elongated segments in combination surrounding the array, the plurality of elongated segments comprising a first elongated segment extending generally in a first direction, wherein the first elongated segment overlaps with the scan driver when viewed in a second direction from the first substrate, wherein the second direction defines the shortest distance between the first and second substrates, wherein the first elongated segment comprises a first portion and a second portion, the first portion being interposed between the scan driver and the second substrate, the second portion being interposed between the first substrate and the second substrate while not interposed between the scan driver and the second substrate, wherein the second portion comprises a first end and a second end, the first end contacting the first substrate, the second end contacting the second substrate, wherein the first end is bonded to the first substrate.
A method of making an organic light emitting display device, the method comprising:
- providing an unfinished product, the product comprising:
- a first substrate;
- a second substrate opposing the first substrate;
- an array of organic light emitting pixels interposed between the first and second substrates;
- a scan driver interposed between the first and second substrates;
- and
- a frit comprising a plurality of elongated segments interposed between the first and the second substrates, the plurality of elongated segments in combination surrounding the array, the plurality of elongated segments comprising a first elongated segment extending generally in a first direction, wherein the first elongated segment overlaps with the scan driver when viewed in a second direction from the first substrate, wherein the second direction defines the shortest distance between the first and second substrates, wherein the first elongated segment comprises a first portion and a second portion, the first portion being interposed between the scan driver and the second substrate, the second portion being interposed between the first substrate and the second substrate while not interposed between the scan driver and the second substrate;
- and
- applying a laser beam to the second portion of the first elongated portion such that the frit interconnects the first substrate and second substrate, wherein the second portion comprises a first end and a second end, the first end contacting the first substrate, the second end contacting the second substrate, wherein the first end is bonded to the first substrate.
