A method of improving the stability of organic light emitting diode (OLED) display devices driven by amorphous silicon thin-film transistors, in which the driving circuitry within each sub-pixel includes a driving transistor for driving organic light emitting diode (OLED), a scanning transistor and a storage capacitance. An end of the capacitance is connected to the signal resetting line, which a resetting time pulse of high potential and low potential are supplied. Since the resetting signals within the sub-pixels are synchronized, a single voltage of the resetting signal can control the positive and negative stresses for each transistor in the sub-pixels on the panel.
