Patent ID: 8513897

Claim:
An organic light emitting diode display with a current stabilizing device comprising: an organic light emitting diode panel being provided with a plurality of organic light emitting diodes, and each of the organic light emitting diodes including a negative electrode and a positive electrode; a data driver including a driving-voltage line and a plurality of data-power-supply wires, the data-power-supply wires being coupled to the negative electrodes of the organic light emitting diodes; a scan driver including a plurality of scan-signal lines coupled to the positive electrodes of the organic light emitting diodes; a current stabilizing device including a voltage boosting unit and a current limiting unit, the voltage boosting unit being coupled to the driving-voltage line to boost a driving voltage of the data driver in order to produce an output voltage which is higher than the driving voltage, the current limiting unit being coupled between the voltage boosting unit and the data-power-supply wires to maintain a data current flowing through the organic light emitting diodes at a constant level by performing current limiting to the output voltage; wherein the current limiting unit and the voltage boosting unit are installed in same stabilizing device, which was controlled by connection resistance of a transistor.
