Abstract

A flat panel display apparatus includes a substrate; a display unit disposed on the substrate; a sealing substrate disposed to face the display unit; a sealing member disposed between the substrate and the sealing substrate to surround the display unit; a wiring unit disposed between the substrate and the sealing substrate, including a region that overlaps the sealing member, and including a plurality of wiring members that are spaced apart from each other in at least a portion of the region that overlaps the sealing member; and a lead-in unit connected to the wiring unit to apply a voltage to the wiring unit, and formed to be electrically connectable to an external power source.

Claims (20)

1. A flat panel display apparatus comprising:

a substrate;

a display unit disposed on the substrate;

a sealing substrate disposed to face the display unit;

a sealing member disposed between the substrate and the sealing substrate to surround the display unit;

a wiring unit disposed between the substrate and the sealing substrate, including a region that overlaps the sealing member; and

a lead-in unit connected to the wiring unit to apply a voltage to the wiring unit, and formed to be electrically connectable to an external power source, the lead-in unit being directly connected to the wiring unit, wherein:

the wiring unit forms a continuous line that overlaps the sealing member, the wiring unit including a first wiring member that surrounds the display unit, and a second wiring member that parallels the first wiring member and surrounds the display unit between the first wiring member and the display unit, the wiring unit further including a first bending region and a second bending region where respective ends of the first wiring member bend to connect to respective ends of the second wiring member to form the continuous line, wherein the first bending region and the second bending region are adjacent to each other, and

the lead-in unit is directly connected only to the first wiring member.

2. The apparatus as claimed in claim 1 , wherein the sealing member contains a frit.

3. The apparatus as claimed in claim 1 , wherein the display unit includes an organic light emitting device.

4. A method of manufacturing a flat panel display apparatus, the method comprising:

providing a substrate; a display unit disposed on the substrate; a sealing substrate disposed to face the display unit; a sealing member precursor disposed between the substrate and the sealing substrate to surround the display unit; a wiring unit disposed between the substrate and the sealing substrate, including a region that overlaps the sealing member precursor; and a lead-in unit connected to the wiring unit to a a voltage to the wiring unit and formed to be electrically connectable to an external power source, the lead-in unit being directly connected to the wiring unit; and

forming a sealing member from the sealing member precursor by:

electrically connecting a power source to the lead-in unit;

applying a voltage from the power source to spaced apart wiring members of the wiring unit; and

melting and curing the sealing member precursor using heat generated from the wiring unit, wherein:

the wiring unit forms a continuous line that overlaps the sealing member, the wiring unit including a first wiring member—that surrounds the display unit, and a second wiring member—that parallels the first wiring member—and surrounds the display unit between the first wiring member and the display unit, the wiring unit further including a first bending region and a second bending region where respective ends of the first wiring member bend to connect to respective ends of the second wiring member to form the continuous line, wherein the first bending region and the second bending region are adjacent to each other, and

the lead-in unit is directly connected only to the first wiring member.

5. The method as claimed in claim 4 , wherein the sealing member contains a frit.
