Abstract

An organic light emitting diode (OLED) display including a display substrate; a sealing member facing the display substrate; a sealant between the display substrate and the sealing member, the sealant cohering the display substrate and the sealing member; a plurality of conductive wires on the display substrate and overlapping the sealant; and a heat blocking film between the conductive wire and the sealant, the heat blocking film including a plurality of sub-heat blocking films.

First claim

What is claimed is:

1. A display, comprising:
a display substrate;
a sealing member facing the display substrate;
a sealant between the display substrate and the sealing member, the sealant cohering the display substrate and the sealing member;
a conductive wire on the display substrate and overlapping the sealant; and
at least two sub-heat blocking films directly contacting and on the conductive wire and between the conductive wire and the sealant,
wherein the at least two sub-heat blocking films are spaced apart along a width direction of the sealant, each of the at least two sub-heat blocking films directly contacting the conductive wire,
wherein the sealant contacts the at least two sub-heat blocking films, and
wherein each of the at least two sub-heat blocking films covers an upper surface and two side surfaces of the conductive wire.

2. The display as claimed in claim 1 , wherein each of the at least two sub-heat blocking films has a triple film structure, the triple film structure including silver (Ag) or ITO/Ag/ITO.

3. The display as claimed in claim 1 , further comprising:
a plurality of conductive wires; and
at least one short circuit blocking film between the plurality of conductive wires.

4. The display as claimed in claim 3 , wherein the at least one short circuit blocking film overlaps the sealant.

5. The display as claimed in claim 3 , wherein the at least one short circuit blocking film includes a plurality of short circuit blocking films disposed along a length direction of the sealant.

6. The display as claimed in claim 5 , wherein each short circuit blocking film of the plurality of short circuit blocking films has a planar rectangular shape.

7. The display as claimed in claim 5 , wherein each short circuit blocking film of the plurality of short circuit blocking films includes a plurality of sub-short circuit blocking films spaced apart from one another along the width direction of the sealant.

8. The display as claimed in claim 7 , wherein each sub-short circuit blocking film of the plurality of sub-short circuit blocking films have a planar quadrangle shape.

9. The display as claimed in claim 3 , further comprising:
a thin film transistor in a display area of the display substrate, and
a driving circuit chip at an edge of the display substrate, the driving circuit chip transferring a driving signal to the thin film transistor,
wherein at least one of the plurality of conductive wires electrically connects the thin film transistor and the driving circuit chip.

10. The display as claimed in claim 9 , further comprising an organic light emitting diode, the organic light emitting diode including a first electrode on the thin film transistor, an organic emission layer on the first electrode, and a second electrode on the organic emission layer.

11. The display as claimed in claim 10 , wherein the at least one short circuit blocking film has a double film structure that includes a lower blocking film and an upper blocking film.

12. The display as claimed in claim 11 , wherein the upper blocking film covers the lower blocking film.

13. The display as claimed in claim 12 , wherein the plurality of conductive wires includes at least one of aluminum (Al), chromium (Cr), molybdenum (Mo), titanium (Ti), tantalum (Ta), Al—Ni—La alloy, and Al—Nd alloy.

14. The display as claimed in claim 12 , wherein the lower blocking film is formed of a same material as the plurality of conductive wires.

15. The display as claimed in claim 11 , wherein:
the at least one short circuit blocking film includes at least two short circuit blocking films between adjacent pairs of conductive wires of the plurality of conductive wires, and
the upper blocking film is formed of the same material as the first electrode.

16. The display as claimed in claim 10 , wherein the at least one short circuit blocking film has a single film structure.

17. The display as claimed in claim 16 , wherein:
the at least one short circuit blocking film includes at least two short circuit blocking films between adjacent pairs of conductive wires of the plurality of conductive wires, and
the at least two single film short circuit blocking films are formed of the same material as the first electrode.
