Abstract

An organic light emitting display device includes a first substrate having a plurality of organic light emitting structures thereon, a second substrate facing the first substrate to encapsulate the organic light emitting structures, an aperture under a lower surface of the first substrate, and an aperture controller under the lower surface of the first substrate. The organic light emitting structures define a pixel area. The second substrate has a light absorption area. The aperture corresponds to the light absorption area. The aperture controller is adjacent to the aperture.

First claim

What is claimed is:

1. An organic light emitting display device comprising:
a camera;
a first substrate on the camera, the first substrate comprising a plurality of organic light emitting structures thereon, the organic light emitting structures defining a pixel area, the pixel area comprising at least one light emitting portion and a light transmitting portion; and
a second substrate facing the first substrate to encapsulate the organic light emitting structures, the second substrate having a light absorption area, the second substrate comprising a reflection pattern thereon,
wherein the camera is disposed corresponding to the light absorption area.

2. The organic light emitting display device of claim 1 , wherein a portion of the pixel area overlaps the light absorption area.

3. The organic light emitting display device of claim 2 , wherein the portion of the pixel area overlapping the light absorption area comprises the light transmitting portion.

4. The organic light emitting display device of claim 1 , wherein the reflection pattern corresponds to a boundary of the pixel area.

5. The organic light emitting display device of claim 1 , wherein the reflection pattern is outside the light absorption area.

6. The organic light emitting display device of claim 1 , wherein the camera comprises a lens part under the first substrate, the lens part corresponding to the light absorption area.

7. The organic light emitting display device of claim 6 , wherein the camera further comprises a light detecting sensor under the lens part, the light detecting sensor for receiving light from the light absorption area.

8. The organic light emitting display device of claim 1 , further comprising an aperture between the camera and the first substrate, the aperture corresponding to the light absorption area.

9. The organic light emitting display device of claim 8 , further comprising an aperture controller between the camera and the first substrate, the aperture controller being adjacent to the aperture.

10. The organic light emitting display device of claim 8 , further comprising a metal pattern corresponding to the light absorption area.

11. The organic light emitting display device of claim 10 , wherein the metal pattern is between the aperture and the first substrate.

12. The organic light emitting display device of claim 10 , wherein the metal pattern comprises substantially the same material as the reflection pattern.

13. The organic light emitting display device of claim 10 , wherein each of the metal pattern and the reflection pattern has a reflectivity greater than about 0.9.

14. The organic light emitting display device of claim 1 , wherein each of the organic light emitting structures comprises a first electrode, an organic light emitting element on the first electrode, and a second electrode on the organic light emitting element.
