Method of preparing organic light emitting device
First Claim
1. A method of preparing an organic light-emitting device, the method comprising:
- forming an organic emission unit on a substrate; and
forming a thin film encapsulation layer that contacts an environmental element, and that comprises at least one inorganic layer comprising a low temperature viscosity transition (LVT) inorganic material,wherein the inorganic layer is formed using a process comprising;
forming a pre-inorganic layer comprising the LVT inorganic material by providing the LVT inorganic material onto the organic emission unit on which the environmental element is located;
performing a first healing process on the pre-inorganic layer at a temperature greater than a viscosity transition temperature of the LVT inorganic material; and
performing a second healing process on the pre-inorganic layer having undergone the first healing process to increase a binding force between the environmental element and the LVT inorganic material, and to increase a binding force among the LVT inorganic material, the second healing process comprising chemical treatment,wherein the pre-inorganic layer having undergone the first healing process is treated with at least one selected from the group consisting of an acidic solution, an alkaline solution, and a neutral solution.

Abstract
A method of preparing an organic light-emitting device includes forming an organic emission unit on a substrate, and forming a thin film encapsulation layer that contacts an environmental element, and that includes at least one inorganic layer including a low temperature viscosity transition (LVT) inorganic material, wherein the inorganic layer is formed using a process including forming a pre-inorganic layer including the LVT inorganic material by providing the LVT inorganic material onto the organic emission unit on which the environmental element is located, performing a first healing process on the pre-inorganic layer at a temperature greater than a viscosity transition temperature of the LVT inorganic material, and performing a second healing process on the pre-inorganic layer having undergone the first healing process to increase a binding force between the environmental element and the LVT inorganic material, and to increase a binding force among the LVT inorganic material.
