Abstract:
1. A method for manufacturing an organic light emitting display (OLED), the method including depositing materials on a substrate using a deposition source, the deposition source comprising: a dopant vaporization source; a first host vaporization source comprising a first crucible of a first vaporization source unit on a side of the dopant vaporization source and a second crucible of a second vaporization source unit on another side of the dopant vaporization source; wherein the first vaporization source unit and the second vaporization source unit comprise linear vaporization sources; wherein each of the first vaporization source unit and the second vaporization source unit each comprises a plurality of nozzles next to each other arranged in a same direction as a direction in which the first vaporization source unit and the second vaporization source unit are arranged; and a second host vaporization source comprising, a third vaporization source unit on the side of the dopant vaporization source and arranged in parallel with the first vaporization source unit, and a fourth vaporization source unit on the another side of the dopant vaporization source and arranged in parallel with the second vaporization source unit.
