Abstract:
A pixel having an organic light emitting diode (OLED) and method for fabricating the pixel is provided. A planarization dielectric layer is provided between a thin-film transistor (TFT) based backplane and OLED layers. A through via between the TFT backplane and the OLED layers forms a sidewall angle of less than 90 degrees to the TFT backplane. The via area and edges of an OLED bottom electrode pattern may be covered with a dielectric cap.

Claim (Index 21):
A pixel having a vertical architecture, comprising:\n an organic light emitting diode (OLED) device having a bottom electrode, one or more OLED layers and a transparent top electrode for emitting light; a thin-film transistor (TFT) based backplane for electrically driving the OLED device, the TFT based backplane being vertically integrated with the OLED layers and located below said bottom electrode to form a top-emitting OLED, the TFT based backplane comprising:\n source and drain nodes; and \n a thin conductive electrode formed at least partially on a flat portion of the pixel area, electrically coupled to a source or drain node, and defined by a top surface, a bottom surface, and side surfaces, its thickness defined by normal distances between the top and bottom surfaces substantially smaller than its horizontal dimensions defined by the side surfaces; \n a planarization dielectric layer provided between the TFT based backplane and the OLED bottom electrode so as to planarize the vertical profile on the TFT based backplane, said planarization dielectric layer being in direct contact with both said TFT based backplane and said OLED bottom electrode; a via in said planarization dielectric layer to provide a communication path between said TFT based backplane and said OLED device and through said thin conductive electrode; and a dielectric layer deposited on top of said bottom electrode and covering said via and all the edges of said bottom electrode while leaving the rest of said bottom electrode uncovered.
