Patent ID: 7205968

Claim:
An organic electro luminescence device comprising: a plurality of anode electrodes to receive an anode power having a predetermined level corresponding to associated image data, the anode power being selectively supplied to each of the anode electrodes by an associated thin film transistor; an associated organic luminescence region comprising an organic luminescence layer material type disposed on each of the anode electrodes; a plurality of cathode electrodes, each of the plurality of cathode electrodes associated with a plurality of organic luminescence regions having a particular luminescence layer material type, each of the cathode electrodes to receive a cathode power based on the associated organic luminescence layer material type; wherein the plurality of anode electrodes are arranged in a matrix configuration, and wherein the associated organic luminescence layer material type for each of the plurality of anode electrodes is selected from the group consisting of red, green and blue organic luminescent material; and wherein a first cathode electrode is associated with a plurality of organic luminescence regions having red luminescent material, a second cathode electrode is associated with a plurality of organic luminescence regions having green luminescent material, and a third cathode electrode is associated with a plurality of organic luminescence regions having blue luminescent material, and wherein the first cathode electrode, the second cathode electrode, and the third cathode electrode are separate from one another.
