Abstract: A driving method is used for driving the voltage-driven circuit of an organic light emitting diode display device. Within a frame period, data voltage is set to a negative data voltage for a pre-defined interval within a frame period. When the scanning voltage is set to a high voltage level, the negative data voltage is applied to the gate terminal of a driving thin film transistor. The gate remains at the negative gate voltage for a maintenance period and the driving thin film transistor has a constant threshold voltage. Hence, this invention provides a mechanism for maintaining a constant luminance from the organic light emitting diode despite an extended use, thus effectively increasing the working life of the display device.

This invention provides two additional thin film transistors to the driving circuit of each pixel of the display. If, during fabrication, positive charges accumulate at the anode of a light-emitting diode so that the anode has a potential larger than the common positive voltage line of the panel, a current will flow from one of the thin film transistors to the common positive voltage line. Conversely, if negative charges accumulate at the anode so that the anode has a potential smaller than the common negative voltage line of the panel, a current will flow from the common negative voltage line to the anode via the other thin film transistor and neutralize the negative charges. If the charges are not neutralized and allowed to accumulate on the anode of the light-emitting device, point defects may be produced.
