Patent ID: 7319290

Claim:
An active matrix organic electro-luminescent display panel, comprising: a pixel structure layer, disposed on a substrate, wherein the pixel structure layer comprises an active device matrix and an anode pattern layer; an organic light-emitting layer, disposed at least over the anode pattern layer, wherein the organic light-emitting layer comprises a first organic light-emitting pattern, a second organic light-emitting pattern and a third organic light-emitting pattern; a cathode layer, disposed on the organic light-emitting layer, wherein the cathode layer comprises a first cathode pattern disposed on the first organic light-emitting pattern, a second cathode pattern disposed on the second organic light-emitting pattern and a third cathode pattern disposed on the third organic light-emitting pattern, and the first, the second and the third cathode patterns are disconnected from each other; wherein the first cathode pattern is electrically connected to a first voltage, the second cathode pattern is electrically connected to a second voltage, the third cathode pattern is electrically connected to a third voltage, and the first voltage, the second voltage and the third voltage are different from each other; and a first, second and third cathode lines electrically connected to the first, the second and the third cathode patterns respectively, wherein the first, second and third cathode lines are sandwiched between the pixel structure layer and the organic light-emitting layer.
