Tiled OLED display

A passive-matrix tiled OLED display structure having a display area, comprising:

• a) a substrate;
• b) one or more electrode busses extending across only a portion of the substrate and located over the substrate which extend over a predetermined portion of said substrate, each of said busses having an electrode pad and a connecting end for connecting to a controller;
• c) an insulator located over only the substrate portion having one or more of the electrode busses wherein said insulator does not cover said electrode pads;
• d) at least three sets of first electrode segments extending at an angle to the electrode busses and located over the entire display area, each set of first electrode segments extending for only a portion of the length of said substrate and designed to be active in a different portion of the display area;
• 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) at least three sets of second electrode segments located parallel to the electrode busses over the one or more layers of organic materials and entire display area and each of said sets of second electrode segments designed to be active in a different portion of the display area, one of said three sets of second electrode segments being in contact with the exposed portion electrode busses, each of said first set of first electrode segments being associated with one set of said three sets of second electrode segments so as to form a plurality of display segments in said display area.

A passive-matrix pixel light emitting 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 having the insulator and over the substrate portion not having the insulator;
• e) one or more layers of 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 parallel to the electrode busses located over the one or more layers of organic 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.
