Abstract
A method and a device for driving an organic light emitting diode display device are provided. The method includes acquiring an equivalent voltage of pixels between a cathode and an input of a negative voltage of a power source according to a video signal; calculating a current voltage of a gate of a driving thin film transistor in a light emitting stage according to the equivalent voltage; and controlling a voltage value of a positive voltage of the power source according to the current voltage of the gate of the driving thin film transistor, so as to reduce power consumption of the organic light emitting diode display device.
