1. A full-color pixel arrangement for an OLED device comprising:
- at least four sub-pixels, each sub-pixel of the at least four sub-pixels configured to emit light having a different peak wavelength than each other pixel of the at least four sub-pixels, and each sub-pixel comprising an emissive region;
wherein the at least four sub-pixels comprise emissive regions of not more than two colors, and the pixel arrangement comprises not more than two color altering layers.

Abstract
Arrangements of pixel components that allow for full-color devices, while using emissive devices that emit at not more than two colors, and/or a limited number of color altering layers, are provided. Devices disclosed herein also may be achieved using simplified fabrication techniques compared to conventional side-by-side arrangements, because fewer masking steps may be required.

31. A full-color pixel arrangement for an OLED device comprising:
-
a first sub-pixel comprising a first emissive region configured to emit a first color; a second sub-pixel comprising a second emissive region configured to emit a second color; a third sub-pixel comprising a third emissive region configured to emit the second color; a fourth sub-pixel comprising a fourth emissive region configured to emit the first color or the second color; a first color altering layer disposed in a stack with the second emissive region; and a second color altering layer disposed in a stack with the third emissive region;
;
;wherein the first, second, third, and fourth sub-pixels together comprise emissive regions of not more than two colors, and the pixel arrangement comprises not more than two color altering layers.
