  • Organic light emitting devices
    Patent number: 6548961
    Abstract: A method of making a light-emitting device comprises forming a first and second components. The first component has a light-transmissive first substrate, light transmissive first electrode layer on the first substrate, an organic layer on the first electrode, and a second electrode layer on the organic layer. The second component has a second substrate and driver array circuitry on the second substrate. The first component and the second component are joined together with the second electrode of the first component facing the driver array of the second component. An electrical contact is formed between one of the first and second electrode layers of the first component and the driver array circuitry of the second component.
    Type: Grant

The first component has a first substrate, a first electrode on the first substrate, an organic layer on the first electrode, and a light-transmissive second electrode on the organic layer. The second component has a light-transmissive second substrate, and a light transmissive, electrically conductive layer on the second substrate. The first and second components are joined with the second electrode of the first component facing the conductive layer of the second component. An electrical contact is formed between the second electrode of the first component and the electrically conductive layer of the second component.
