Embodiments described herein may provide for devices comprising a power efficient RGBW display. In some embodiments, a first device may be provided. The first device may include at least one pixel. The pixel may include a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel. The first sub-pixel may include a first color filter in optical communication with a first organic light emitting device. The second sub-pixel may include a second color filter in optical communication with a second organic light emitting device. The third sub-pixel may include a third color filter in optical communication with a third organic light emitting device. The fourth sub-pixel may include a fourth organic light emitting device and emits near white light. At least one of the first sub-pixel or the second sub-pixel may include a color conversion layer in optical communication with the first or second organic light emitting device.
