Abstract:
1. A passive-matrix tiled OLED display structure, comprising: a) a substrate; b) one or more electrode busses extending across only a portion of the substrate and located over the substrate; c) an insulator located over only the substrate portion having one or more of the electrode busses and exposing a pad portion of the electrode buss; d) two or more first electrode segments extending at an angle to the electrode busses and located over the substrate portion having the insulator and over the substrate portion not having the insulator; e) one or more layers of organic materials, at least one of which comprises light emissive materials, located over the first electrode segments, the layer(s) having openings to expose the pad portion of at least one of the electrode busses; and f) two or more second electrode segments located parallel to the electrode busses over the one or more layers of organic materials and in contact with the exposed portion of an electrode bus such that the one or more second electrode segments define one or more pixels in cooperation with the first electrode segments and such that at least one of the first electrode segments is insulated from the at least one of the second electrode segments.
