Claim Text:
1. A method of fabricating a full-color active matrix organic light emitting display comprising the steps of: providing a transparent substrate formed of one of glass, organic film, or a combination thereof and one of rigid or flexible; positioning a color filter on an upper surface of the substrate; depositing a spacer layer on the upper surface of the color filter; forming a metal oxide thin film transistor backpanel on the spacer layer and defining an array of pixels; positioning an array of organic light emitting devices/pixel elements on the backpanel to emit light downwardly through the backpanel, the spacer layer, the color filter, and the substrate in a full-color display, each pixel element being designed to emit light including the wavelength ranges of three primary colors, and each pixel element being further designed to emit either a first emission band with wavelengths substantially extending across the range of two of the primary colors of the three primary colors or a second emission band with wavelengths substantially extending across the range of the remaining primary color of the three primary colors; and forming the color filter with at least three primary color zones corresponding to the three primary colors of the array of organic light emitting devices/pixel elements for each pixel in the array of pixels, two zones of the at least three primary color zones separating the first emission band into two separate primary colors of the three primary colors and a third zone of the at least three primary color zones passing the second emission band as a third primary color of the three primary colors.
