Classification: CPC G  Y | IPC G

Claim 1:
2. A driving method, comprising:
providing a data signal according to a first scan signal by a first transistor;
providing a start signal according to the data signal by a second transistor;
outputting a driving signal according to the start signal by a driving transistor;
providing an initial signal according to the first scan signal by a third transistor, wherein the third transistor is coupled to a capacitor, wherein the capacitor comprises a first terminal and a second terminal; and
receiving the driving signal to emit light by a light emitting diode, wherein the light emitting diode comprises an anode terminal, wherein the anode terminal is coupled to the driving transistor;
wherein during a first period, the capacitor stores the data signal and the initial signal in the first terminal and the second terminal respectively according to the first scan signal;
wherein during a second period, the capacitor stores a first compensation signal and a sum of a pull-down signal and a light emitting diode signal in the first terminal and the second terminal respectively according to the start signal, wherein the first compensation signal is formed by a sum of the pull-down signal of the second terminal and the light emitting diode signal through an electrical coupling of the capacitor, wherein the driving transistor outputs the driving signal according to a second compensation signal, wherein the second compensation signal is a difference between the first compensation signal and a threshold voltage of the second transistor, wherein the light emitting diode is configured to receive the driving signal to emit light.
