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.
Claims31
A multicolor OLED pixel structure, comprising:
- a plurality of light emitting color elements, each color element emitting light of a particular color;
- the optical centers of the color elements coinciding substantially at an optical center for the pixel structure;
- any portion of a color element of the pixel structure having an equally luminous portion of the same color element located diametrically opposite thereto with respect to the optical center of the pixel structure.
An array of pixel structures, each pixel structure being located on a substrate, each pixel structure comprising:
- a plurality of light emitting color elements, each color element emitting light of a particular color;
- the optical centers of the color elements coinciding substantially at an optical center for the pixel structure;
- any portion of a color element of the pixel structure having an equally luminous portion of the same color element located diametrically opposite thereto with respect to the optical center of the pixel structure.
The array according to 21, wherein each pixel structure has a plurality of conducting areas local to each pixel for connection to a PCB.
