Patent ID: 7837530

Claim:
A method of making an organic light emitting display device, the method comprising: providing a first substrate and a first fit bonded to the first substrate; providing a second substrate and an array of organic light emitting pixels formed on the second substrate, the second substrate made of a single layer or multiple layers; arranging the first substrate and the second substrate so as to oppose each other and interpose the array therebetween; interposing a second frit between the first frit and the second substrate, the second fit forming a closed loop surrounding the array, the second fit is configured to melt substantially easier than the first frit upon irradiation of a laser or infrared beam thereto; and bonding the second frit to the first frit and to the second substrate, thereby forming an integrated frit seal interposed between the first and second substrate wherein the frit seal, the first substrate and the second substrate together define an enclosed space in which the array is located; wherein the second frit is substantially non-transparent.
