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 first substrate having a plurality of organic light emitting structures thereon, the organic light emitting structures defining a pixel area;
a second substrate facing the first substrate to encapsulate the organic light emitting structures, the second substrate having a light absorption area;
an aperture under a lower surface of the first substrate corresponding to the light absorption area; and
an aperture controller under the lower surface of the first substrate, the aperture controller being adjacent to the aperture.

2. 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.

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

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

5. The organic light emitting display device of claim 4 , wherein a size or a shape of the light transmitting portion is adjustable according to an open area of the aperture.

6. The organic light emitting display device of claim 1 , further comprising a metal pattern between the first substrate and the aperture.

7. The organic light emitting display device of claim 6 , further comprising a reflection pattern under a lower surface of the second substrate, the reflection pattern corresponding to a boundary of the pixel area.

8. The organic light emitting display device of claim 7 , wherein the reflection pattern is outside the light absorption area.

9. The organic light emitting display device of claim 7 , wherein the metal pattern comprises substantially the same material as the reflection pattern.

10. The organic light emitting display device of claim 9 , wherein each of the metal pattern and the reflection pattern has a reflectivity greater than about 0.9.

11. The organic light emitting display device of claim 1 , further comprising a lens part under a lower surface of the aperture, the lens part corresponding to the light absorption area.

12. The organic light emitting display device of claim 11 , further comprising a light detecting sensor under the lens part, the light detecting sensor for receiving light from the light absorption area.

13. The organic light emitting display device of claim 1 , further comprising a sealant sealing the first substrate and the second substrate.

14. The organic light emitting display device of claim 1 , further comprising a moisture absorbent under a lower surface of the second substrate.

15. The organic light emitting display device of claim 1 , wherein each of the organic light emitting structures comprises a red light emitting structure, a green light emitting structure, and a blue light emitting structure.

16. An organic light emitting display device comprising:
a display panel comprising:
a first substrate having a plurality of organic light emitting structures thereon, the organic light emitting structures defining a pixel area;
a second substrate facing the first substrate to encapsulate the organic light emitting structures, the second substrate having a light absorption area;

an aperture controller under the lower surface of the first substrate, the aperture controller being adjacent to the aperture; and

at least one camera integrally formed with the display panel, the camera comprising a lens part under the aperture corresponding to the light absorption area.

17. The organic light emitting display device of claim 16 , further comprising a plurality of cameras comprising the at least one camera,
wherein the second substrate has a plurality of light absorption areas comprising the light absorption area, the light absorption areas corresponding to the cameras, and
wherein the display panel comprises a plurality of apertures corresponding to the light absorption areas.

18. The organic light emitting display device of claim 17 , wherein the cameras are configured to detect a plurality of images having a predetermined parallax.

19. The organic light emitting display device of claim 16 , wherein a portion of the pixel area overlaps the light absorption area.

20. The organic light emitting display device of claim 19 , wherein the portion of the pixel area overlapping the light absorption area comprises a light transmitting portion.
