Abstract
A full-color AM OLED includes a transparent substrate, a color filter positioned on an upper surface of the substrate, and a metal oxide thin film transistor backpanel positioned in overlying relationship on the color filter and defining an array of pixels. An array of OLEDs is formed on the backpanel and positioned to emit light downwardly through the backpanel, the color filter, and the substrate in a full-color display. Light emitted by each OLED includes a first emission band with wavelengths extending across the range of two of the primary colors and a second emission band with wavelengths extending across the range of the remaining primary color. The color filter includes for each pixel, two zones separating the first emission band into two separate primary colors and a third zone passing the second emission band.
