Driving method for light emitting display device

A method of operating a display device that comprises a driving transistor, a light emitting diode, and a storage capacitor, the method comprising:

• throughout a light emitting period, transmitting an output current through the driving transistor to the light emitting diode for the light emitting diode to emit light;
• throughout a pre-bias period, applying a bias voltage to a source electrode of the driving transistor;
• throughout an anode reset period, initializing an anode of the light emitting diode;
• throughout a gate initialization period, initializing a gate electrode of the driving transistor;
• throughout a drain initialization period, initializing a drain electrode of the driving transistor;
• and
• throughout a threshold voltage compensation and data writing period, compensating for a threshold voltage of the driving transistor, and writing a data voltage to the storage capacitor,
• wherein an odd number of scan-signal lengths immediately follow the light emitting period and immediately precede the drain initialization period.
