Abstract
Arrangements of pixel components that allow for full-color devices, while using emissive devices that use blue color altering layers in conjunction with blue emissive regions, that emit at not more than two colors, and/or that use 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.
