Organic light emitting display and method of fabricating the same

摘要

An organic light emitting display in which differential pressure is controlled to prevent Newton's rings from being generated and a method of fabricating the same are provided. The organic light emitting display includes a first substrate including a pixel region in which at least one organic light emitting diode (OLED) is formed and a non-pixel region, a second substrate attached to one region including the pixel region of the first substrate, and a frit provided between the non-pixel region of the first substrate and the second substrate. At least one of the first substrate and the second substrate is formed to be convex outward.

主权项

1. A method of making an organic light emitting display (OLED) device, the method comprising:
providing a first substrate and an array of organic light emitting pixels, the array being formed over the first substrate; providing a second substrate and a frit, the frit formed on the second substrate to surround the array; attaching the first substrate and the second substrate to each other under a predetermined gas pressure, wherein the predetermined gas pressure is higher than 760 Torr; subjecting the device to a pressure less than the predetermined gas pressure so as to form a curvature in the second substrate due to a difference in pressure; and heating the frit, wherein the frit, the first substrate, and the second substrate in combination define an enclosed space in which the array is located, wherein the frit substantially hermetically seals the enclosed space.
