Abstract
An organic light-emitting diode display may have an array of pixels with sets of pixels arranged in rows and columns. Each set of pixels includes a red pixel, a green pixel, a blue pixel, and a white pixel. The red pixels each have a white diode and a red color filter element to impart a red color to white light from that white diode. The green pixels each have a white diode and a green color filter element to impart a green color to white light from that white diode. The white pixels each have an unfiltered white diode. The blue pixels each have an unfiltered blue diode. The unfiltered white and blue diodes do not have color filters and emit white and blue light for the white and blue pixels, respectively. The white and blue diodes may be tandem diodes having two or more emissive layers.
