Abstract
An electronic device may include a display having an array of organic light-emitting diode display pixels. Color filter elements may be used to allow the display to present color images. A blue subpixel may be formed using part of an emissive layer and red and green subpixels may share a separate second part of the emissive layer. In four-subpixel designs, a white or yellow subpixel may also share the emissive layer with the red and green subpixels. Tandem diode configurations may be used in which a blue subpixel has two blue diodes connected in series and other subpixels are formed from respective pairs of series-connected diodes. A pixel definition layer may be formed from a light-absorbing material to suppress ambient light reflections.
