Abstract
The present invention provides an organic light emitting diode unit including: a bar-shaped organic light emitting diode body; a glass protective tube having at least one opening and housing the organic light emitting diode body; and at least one seal cover provided with a moisture absorbent at the side facing the opening and closes at least one opening of the glass protective tube, and a method of manufacturing the organic light emitting diode unit.
Claims17
An organic light emitting diode unit, comprising:
- a bar-shaped organic light emitting diode body;
- a glass protective tube having at least one opening and housing the organic light emitting diode body;
- and
- at least one seal cover provided with a moisture absorbent at the side facing the opening and closing at least one opening of the glass protective tube.
A method of manufacturing an organic light emitting diode unit, the method comprising the steps of:
- (a) providing a base bar;
- (b) depositing a first electrode around the base bar while rotating the base bar;
- (c) depositing an organic layer around the outside of the first electrode while rotating the base bar with the first electrode;
- (d) depositing a second electrode around the outside of the organic layer while rotating the base bar with the first electrode and organic layer;
- (e) housing the organic light emitting diode body manufactured through the steps (a) to (d) inside a glass protective tube having at least one opening;
- and
- (f) sealing the glass protective tube by closing at least one opening of the glass protective tube with at least one seal cover provided with a moisture absorbent at the side facing the opening.
A method of manufacturing an organic light emitting diode unit, the method comprising the steps of:
- (a) providing a bar-shaped first electrode;
- (b) depositing an organic layer around the outside of the first electrode while rotating the first electrode;
- (c) depositing a second electrode around the outside of the organic layer while rotating the first electrode with the organic layer;
- (d) housing the organic light emitting diode body manufactured through the steps (a) to (c) inside a glass protective tube having at least one opening;
- and
- (e) sealing the glass protective tube by closing at least one opening of the glass protective tube with at least one seal cover provided with a moisture absorbent at the side facing the opening.
