Driving circuit and method for light emitting device

A driving circuit for a light-emitting device, comprising:

• a driving transistor, including a gate;
• a light-emitting device, coupled to the driving transistor in series to form a light-emitting path, wherein an on/off state of the driving transistor determines an on/off state of the light-emitting path;
• a first transistor, having a source region coupled to a data line, a drain region coupled to the gate of the driving transistor, and a gate coupled to a first scan line;
• a second transistor, having a source region coupled to a reference low voltage,
• a drain region coupled to the gate of the driving transistor, and a gate coupled to a second scan line, wherein clock pulses of the first and second scan lines have the same frequency, and the second scan line delays from the first scan line by a delay time;
• and
• a maintaining capacitor, coupled to the gate of the driving transistor to maintain a voltage state thereof.

A driving method of a driving circuit for driving a light-emitting device which comprises a light-emitting unit and a control transistor, wherein the control transistor is controlled by a scan line and a data line to output a control signal to an input terminal of the light-emitting unit, the method comprising:

• providing a reset device operative to output a voltage signal by a clock;
• setting the clock of the reset device, such that a clock of the scan line and the clock of the reset device have the same frequency, while the clock of the reset device is delayed by a delay time;
• and
• outputting the voltage signal to the input terminal of the light-emitting unit, according to the clock of the reset device, such that the light-emitting unit temporarily stops illuminating.
