## Abstract

An organic light emitting diode (OLED) display is disclosed. In one embodiment, the OLED display includes first and second substrates, an OLED interposed between the first and second substrates and an external sealant formed between the first and second substrates and configured to i) substantially seal the first and second substrates and ii) substantially surround the OLED. The OLED display may further include a dam formed between the external sealant and the OLED and configured to substantially surround the OLED, and a getter formed between the external sealant and the dam.

## Claims

### Claim 1

An organic light emitting diode (OLED) display comprising:
first and second substrates;
an OLED interposed between the first and second substrates;
an external sealant formed between the first and second substrates and configured to i) substantially seal the first and second substrates and ii) substantially surround the OLED, wherein the external sealant is formed at least partially of a light curable material;
a dam formed between the external sealant and the OLED and configured to substantially surround the OLED, wherein the dam is formed at least partially of a thermosetting material and a moisture absorption material; and
a getter formed between the external sealant and the dam, wherein the getter is formed of a material different from at least one of the external sealant and the dam.

### Claim 2 (depends on 1)

The OLED display of claim 1, wherein the getter is configured to be cured from liquid to solid.

### Claim 3 (depends on 1)

The OLED display of claim 1, further comprising an internal sealant formed between the external sealant and the getter.

### Claim 4 (depends on 3)

The OLED display of claim 3, wherein the internal sealant is formed at least partially of a thermosetting material.

### Claim 5 (depends on 1)

The OLED display of claim 1, wherein the getter is formed of a moisture absorption material.

### Claim 6 (depends on 1, 2, 3, 4)

The OLED display of any one of claims 1, 2-4, and 5, wherein the second substrate is an opaque substrate, and wherein the OLED is configured to emit light in a direction of the first substrate.
