Abstract
A lighting system includes a plurality of organic light emitting diode (OLED) devices. By selecting the plurality of OLED devices, or by selectively controlling the plurality of OLED devices, the color characteristics of the lighting system can be tuned. The lifetime of the lighting system can be improved.
Claims29
-21. (canceled)
A lighting system comprising:
- a plurality of organic light emitting diode (OLED) devices,
- wherein each of the plurality of OLED devices has an active region,
- wherein at least some of the OLED devices have active regions of different sizes, and
- wherein the sizes are such that the OLED devices having active regions of different sizes have substantially matching lifetimes.

-45. (canceled)
A method comprising:
- selecting a plurality of organic light emitting diode (OLED) devices to be used in a lighting system,
- wherein each of the plurality of OLED devices has an active region,
- wherein at least some of the OLED devices have active regions of different sizes,
- wherein the different sizes are selected such that light emitted from the lighting system has desired color characteristics and that the OLED devices having active regions of different sizes have substantially matching lifetimes.
