Organic light-emitting display device and method of fabricating the same
First Claim
1. A method of manufacturing an organic light-emitting display device, the method comprising:
- providing a first unfinished product comprising a first substrate and an array of organic light-emitting pixels formed over the first substrate, the first unfinished product further comprising a first frit structure formed over the first substrate and surrounding the array, the first frit structure comprising a first surface generally facing away from the first substrate;
providing a second unfinished product comprising a second substrate and a second frit structure formed over the second substrate, the second frit structure comprising a second surface generally facing away from the second substrate;
arranging the first and second unfinished products such that the first and second surfaces face and contact each other; and
melting and solidifying at least part of the first and second frit structures where the first and second frit structures contact so as to bond the first and second frit structures together, thereby forming an integrated frit seal interposed between the first and second substrate.

Abstract
Disclosed is a method for preparing an organic light-emitting display device in which a substrate and an encapsulation substrate are completely coalesced using a frit. The method for preparing an organic light-emitting display device according to one aspect of the present invention includes a first substrate including an organic light-emitting diode and a second substrate for encapsulating at least a pixel region of the first substrate, the method including applying a first frit paste to surround the pixel region in the first substrate, and applying a second frit paste to be faced against the first frit paste in the second substrate, sintering the first and the second frit pastes to form a first frit and a second frit, respectively, coalescing the first substrate to the second substrate to contact the first frit and the second frit to each other, attaching the first substrate and the second substrate to each other by irradiating a laser or an infrared ray to the first frit and the second frit, both contacted to each other.
