The present invention introduces a novel design for active matrix
displays, utilizing both organic light-emitting diode (OLED) and
thin-film electroluminescent technologies. In a first aspect there is
provided a top-emitting OLED, including an optical interference
contrast-enhancing stack that is placed on the top of the driving
thin-film transistor, and which extendes to the entire pixel area to
cover the reflecting parts of the pixel. In a second aspect, there is
provided a bottom-emitting OIED wherein an optical interference
contrast-enhancing stack is placed right under the driving thin-film
transistor and, separately between the organic stack and the top
electrode, typically a cathode. The optical interference
contrast-enhancing stack suppresses light reflection from the thin-film
transistor and the upper electrode. In the top emitting design, the
optical interference contrast-enhancing stack is placed on the top of the
thin-film transistor source and drain electrodes as well as on the top of
the opaque bottom electrode. A method of achieving substantial uniformity
across a display having multiple areas of optical interference members is
also provided.
