Abstract

A preparing method of an organic light-emitting display device, completely encapsulating a substrate and an encapsulation substrate with a frit and a supplement member is disclosed. It is an aspect of the present invention to provide an organic light-emitting display device comprising: a first substrate comprising a pixel region and a non-pixel region on the side thereof wherein an organic light-emitting element is formed in the pixel region and the non-pixel region is formed in the outer side of the pixel region; a second substrate bonded to one region including the pixel region of the first substrate; encapsulating member provided between the non-pixel region of the first substrate and the second substrate and adhering the first substrate to the second substrate; and supplement member configured of resin formed to be spaced from the frit.

Claims

1. A method of making an organic light emitting display (OLED), the method comprising:

providing a device comprising;

a first substrate,

a second substrate placed over the first substrate,

an array of organic light-emitting pixels interposed between the first and second substrates,

a frit interposed between the first and second substrates while surrounding the array, wherein the frit, the first substrate and the second substrate in combination define an enclosed space in which the array is located, and

an uncured resin structure interposed between the first and second substrates and contacting the first and second substrates, wherein the uncured resin structure contacts or does not contact the frit seal;

curing the uncured resin structure so as to form a reinforcing structure bonding the first and second substrates; and

applying a laser or infrared beam to the frit so as to bond the frit to the first and second substrates.

2. The method of claim 1, wherein the resin structure comprises one or more selected from the group consisting of epoxy, acryl, and urethane resin.

3. The method of claim 1, wherein the reinforcing structure is inside the enclosed space.

4. The method of claim 1, wherein the reinforcing structure is outside the enclosed space.

5. The method of claim 1, wherein curing the uncured resin structure comprises applying UV or heat to the uncured resin structure.

6. The method of claim 1, wherein curing the uncured resin structure is conducted prior to applying the laser or infrared beam.

7. The method of claim 1, wherein curing the uncured resin structure is conducted subsequent to applying the laser or infrared beam.

8. The method of claim 1, wherein the device further comprises:

a plurality of additional arrays of organic light-emitting pixels interposed between the first and second substrates;

a plurality of additional frits interposed between the first and second substrates, each of the additional frits surrounding a respective one of the additional arrays; and

a plurality of additional uncured resin structures interposed between the first and second substrates, the additional uncured resin structures being either or both of inside and outside the enclosed spaces of the additional frits.

9. The method of claim 8, further comprising:

curing the additional uncured resin structures to form a plurality of reinforcing structures interconnecting the first and second substrates; and

cutting the resulting product into a plurality of pieces, each comprising a cut-portion of the first substrate, a cut-portion of the second substrate, the array of organic light-emitting pixels, the frit, and the reinforcing structure.
