Abstract

A transparent emissive device is provided. The device may include one or more OLEDs having an anode, a cathode, and an organic emissive layer disposed between the anode and the cathode. In some configurations, the OLEDs may be non-transparent. The device may also include one or more locally transparent regions, which, in combination with the non-transparent OLEDs, provides an overall device transparency of 5% or more.

First claim

The invention claimed is:

1. A device comprising:
a light emitting surface comprising a first region and a second region;
wherein the device transmits light through the first region and emits light from the second region, wherein the first region is transparent and the second region is substantially non-transparent, regardless of power being applied to the device; and
wherein the device has an overall transparency of at least 5%.

2. The device as recited in claim 1 , wherein the device is a display.

3. The device as recited in claim 2 , wherein the device is a full-color display.

4. The device as recited in claim 1 , wherein the second region has a local transparency of less than 5%.

5. The device as recited in claim 1 , wherein the second region has a local transparency of less than 1%.

6. The device as recited in claim 1 , wherein the device has an overall transparency of at least 10%.

7. The device as recited in claim 1 , wherein the second region has a local transparency of less than 1% and wherein the device has an overall transparency of at least 10%.

8. The device as recited in claim 1 , wherein the device comprises a plurality of OLEDs, each of the plurality of OLEDs configured to emit light through the first region of the light emitting surface.

9. The device as recited in claim 8 , wherein each of the plurality of OLEDs is configured to emit light only through the first region.

10. The device as recited in claim 9 , wherein the device is a full-color display.

11. The device as recited in claim 9 , wherein the second region has a local transparency of less than 5%.

12. The device as recited in claim 9 , wherein the device has an overall transparency of at least 10%.

13. The device as recited in claim 8 , wherein the plurality of OLEDs occupy not more than about 75% of the total area of the display.

14. The device as recited in claim 13 , wherein at least 70% of the area of the display not occupied by the plurality of OLEDs has a local transparency of at least 25%.

15. The device as recited in claim 13 , wherein at least 70% of the area of the display not occupied by the plurality of OLEDs has a local transparency of at least 50%.

16. The device as recited in claim 13 , wherein the device comprises a plurality of regions, each region containing:
one or more of the plurality of OLEDs; and
a transparent region having a local transparency of at least 25%.

17. The device as recited in claim 16 , wherein transparent regions within the plurality of regions together occupy at least 25% of the total area of the light emitting surface.

18. The device as recited in claim 8 , wherein the device is an AMOLED display.

19. The device as recited in claim 8 , wherein each of the plurality of OLED devices is a white-emitting device, further comprising a color filter layer disposed over each of the plurality of OLED devices.

20. The device as recited in claim 1 , wherein the display comprises a plurality of OLED devices disposed on a plastic substrate.

21. The device as recited in claim 1 , wherein the device is flexible.

22. The device as recited in claim 1 , further comprising a single layer barrier encapsulation layer disposed over the first surface of the device.

23. The device of claim 1 , wherein the first region comprises an emissive layer and no more than one electrode.
