1. A driving circuit, comprising:
a first driving transistor, having a first end to receive a power voltage, a control end of the first driving transistor receiving a first control signal, and a second end of the first driving transistor being coupled to a light emitting component; and
a second driving transistor, having a first end to receive a power voltage, a control end of the second driving transistor receiving a second control signal, and a second end of the second driving transistor being coupled to the second end of the first driving transistor,
wherein the first driving transistor provides a first driving current to the light emitting component according to the first control signal, and the second driving transistor provides a second driving current to the light emitting component according to the second control signal,
wherein a voltage difference between a first end and a second end of the first driving transistor is greater than a threshold voltage of the first driving transistor: a voltage difference between a first end and a second end of the second driving transistor is greater than a threshold voltage of the second driving transistor.
