1. A region of a display having a plurality of independently-addressable pixels, each pixel capable of emitting a spectrum comprising:
- a red component having a peak wavelength in the visible spectrum of 580-700 nm;
a green component having a peak wavelength in the visible spectrum of 500-600 nm;
a light blue component having a peak wavelength in the visible spectrum of 400-500 nm; and
a deep blue component having a peak wavelength in the visible spectrum of 400-500 nm and at least 4 nm less than the peak wavelength of the light blue component;
wherein a first of the plurality of pixels and a second of the plurality of pixels share at least one organic light emitting device; and
wherein the first pixel comprises;
a first red-emitting organic light emitting device configured to emit light having a peak wavelength in the visible spectrum of 580-700 nm,a first green-emitting organic light emitting device configured to emit light having a peak wavelength in the visible spectrum of 500-600 nm;
a first light blue-emitting organic light emitting device configured to emit light having a peak wavelength in the visible spectrum of 400-500 nm;
a first deep blue-emitting organic light emitting device configured to emit light having a peak wavelength in the visible spectrum of 400-500 nm and at least 4 nm less than the peak wavelength of the first light blue organic light emitting device.

Abstract
A device such as a display region that includes a plurality of multi-color pixels is provided. Each pixel may have several types of organic light emitting devices that operate as sub-pixels, and at least one type of device may be shared by multiple pixels. Less-used and/or more efficient device types, such as deep blue and green light emitting devices, may be shared between multiple pixels, leading to an improved aperture ratio and fill factor for the device.
