Abstract: An electronic device may include a display having an array of organic light-emitting diode display pixels that produce light that forms an image. Color filter elements may be used to allow the display to present color images. Each display pixel may have a red subpixel, a blue subpixel, a green subpixel, and a white subpixel. To adjust the color coordinates of the white pixel and thereby ensure that the light from the white pixel has a desired white point, part of the white subpixel may be overlapped by an area of colored color filter material. The white subpixel may, for example have a rectangular white area within which a patch of blue color filter material may be provided to make the white light from the white subpixel more bluish than it would be without the patch of blue color filter material.
