    Abstract: Embodiments of the disclosed subject matter provide an organic light emitting diode (OLED) device having a full-color pixel arrangement having a plurality of pixels, with each pixel including a first sub-pixel having a first emissive region configured to emit a first color of light, a second sub-pixel having a second emissive region configured to emit a second color of light, a third sub-pixel having a third emissive region configured to emit a third color of light, and a fourth sub-pixel having the third emissive region and a first color altering layer disposed over at least a portion of the third emissive region. The fourth sub-pixel may be configured to emit a fourth color that is different than the third color. Only one of the first sub-pixel, the second sub-pixel, the third sub-pixel, and the fourth sub-pixel may be configured to emit blue light or red light.
