Light emitting display and method of manufacturing the same
View Patent ↗The present invention is to provide an organic light emitting display and a method of manufacturing the same. The light emitting display according to the present invention includes: a first substrate on which a plurality of light emitting devices having first electrodes, organic light emitting layers, and second electrodes are disposed; a second substrate disposed to face the first substrate; a dam member disposed between the first substrate and the second substrate to surround the plurality of light emitting devices; an inorganic sealing material disposed between the first substrate and the second substrate in an outer area of the dam member and attaching the first substrate to the second substrate; and a silicon filling material provided between the first substrate and the second substrate inward of the dam member to be in contact with the second electrodes.
1. A light emitting display comprising:
a first substrate on which a plurality of light emitting devices comprising first electrodes, organic light emitting layers, and second electrodes are disposed;
a second substrate disposed to face the first substrate;
a dam member disposed between the first substrate and the second substrate to surround the plurality of light emitting devices;
an inorganic sealing material disposed between the first substrate and the second substrate in an outer area of the dam member and attaching the first substrate to the second substrate; and
a silicon filling material provided between the first substrate and the second substrate inward of the dam member to be in contact with the second electrodes.
2. The light emitting display as claimed in claim 1 , wherein the dam member comprises an inorganic material.
3. The light emitting display as claimed in claim 2 , wherein the inorganic material comprises frit.
4. The light emitting display as claimed in claim 2 , wherein a reflecting layer that reflects a laser and/or infrared rays is disposed on a surface of the dam member.
5. The light emitting display as claimed in claim 4 , wherein the reflecting layer comprises at least one selected from the group consisting of Au, Ag, Pt, and Al.
6. The light emitting display as claimed in claim 2 , wherein the dam member is disposed to be in contact with the inorganic sealing material.
7. The light emitting display as claimed in claim 1 , wherein the dam member comprises an organic material.
8. The light emitting display as claimed in claim 7 , wherein the organic material comprises at least one selected from the group consisting of epoxy, epoxy acrylate, bisphenol A type epoxy, cycloaliphatic epoxy resin, phenyl silicone resin, or rubber, and acrylic epoxy resin.
9. The light emitting display as claimed in claim 7 , wherein the dam member is disposed to be spaced away from the inorganic sealing material.
10. The light emitting display as claimed in claim 9 , wherein the dam member and the inorganic sealing material are spaced away from each other by 50 μm or more.
11. The light emitting display as claimed in claim 1 , wherein the inorganic sealing material comprises frit.
12. The light emitting display as claimed in claim 11 , wherein the frit is formed from a material configured to be melted by application of one or more of a laser and infrared rays to the frit.
13. The light emitting display as claimed in claim 12 , wherein the frit comprises a transition metal compound.
14. The light emitting display as claimed in claim 1 , wherein the inorganic sealing material is inhibited from contact with the silicon filling material by the dam member.
