Patent ID: 7901961

Claim:
A method of making an organic light emitting display device comprising: providing a partially fabricated organic light emitting display device comprising a first substrate including a pixel region and a non-pixel region outside the pixel region, a second substrate, and an integrated structure formed on the first substrate, wherein the integrated structure comprises an array of organic light-emitting pixels interposed between the first and second substrates and over the pixel region of the first substrate, and a power supply line configured to supply power to the array; forming a frit seal comprising a plurality of substantially straight segments between the first and second substrates so as to surround the array, wherein the frit seal, the first substrate and the second substrate in combination define an enclosed space in which the array is located; and irradiating laser or infrared rays to the frit seal in a direction generally perpendicular to the second substrate such that the frit seal is molten and cured; wherein the power supply line is formed over the non-pixel region of the first substrate, comprises a first portion extending substantially parallel to a first one of the plurality of substantially straight segments and a top surface facing the second substrate, wherein the frit seal is formed such that a first segment of the frit seal overlaps with the first portion of the power supply line when viewed from the second substrate, and wherein less than about 10% of the top surface of the first portion overlaps with the first segment when viewed from the second substrate.
