Abstract
The present invention provides a multicolor OLED pixel structure having a plurality of light emitting color elements, each color element emitting light of a particular color. Optical centers of the color elements coincide substantially at an optical center for the pixel structure and any portion of a color element of the pixel structure has an equally luminous portion of the same color element located diametrically opposite thereto with respect to the optical center of the pixel structure. Light from all the color elements adds to be able to form emitted white light. A plurality of pixel structures may be formed into an array for an active or passive display.
