Abstract
The disclosed technical solution relates to an organic light emitting diode driving circuit, and a display panel, a display and a driving method using the same. The organic light emitting diode driving circuit includes a driving unit, a threshold compensation unit and an organic light emitting diode. The preferred threshold compensation unit comprises 5 transistors and a capacitance. The organic light emitting diode driving circuit compensates the threshold voltage Vth of the driving transistor by means of this 6T1C circuit, eliminates the inconsistent operation states of the organic light emitting diode caused by the different threshold voltages of the driving transistor in the entire circuit, thereby solving the problem regarding the brightness and evenness of the organic light emitting diode.
