Abstract
A method of encapsulating an organic device including flash evaporating a getter layer on the substrate is disclosed. The getter layer comprises an alkaline earth metal, such as barium. The getter layer serves to protect the active components by absorbing surrounding moisture and gases.
Claims32
A method of encapsulating an organic device, comprising:
- providing a substrate having an active region defined thereon, the active region comprising an active component;
- flash evaporating a getter layer on a surface of the active component in the active region, the getter layer comprising an alkaline earth metal;
- and
- mounting a cap onto the substrate to seal the active region.
A method of encapsulating an organic device comprising:
- providing a substrate having an active region defined thereon, the active region comprising an active component, wherein the active component comprises at least one OLED cell to form an OLED device;
- flash evaporating a getter layer on the active component, the getter layer comprising an alkaline earth metal;
- and
- mounting a cap onto the substrate to seal the active region.
A method of encapsulating an organic device, comprising:
- providing a substrate having an active region defined thereon, the active region comprising an active component;
- aligning the substrate and at least one getter source in a vacuum chamber;
- activating the getter source;
- flash evaporating a getter layer on a surface of the active component located in the active region, the getter layer comprising an alkaline earth metal;
- and
- mounting a cap onto the substrate to seal the active region.

A method of encapsulating a device comprising:
- providing a substrate having an active region defined thereon, the active region comprising an active component, the active component including at least one OLED cell;
- forming a getter layer on a surface of the active component;
- and
- mounting a cap onto the substrate to seal the active region.
An organic electronic device, comprising:
- a substrate, having an active region defined thereon, the active region including an active component;
- a getter layer deposited directly on the active region, the getter layer including an alkaline earth metal;
- and
- a cap mounted over the active region to seal the active region.
