Claim Text:
1. A driving circuit, comprising: an activating end for selectively outputting a first voltage control signal and a second voltage control signal; an operation switch coupled with the activating end, wherein the operation switch is driven to be deactivated when the operation switch receives the first voltage control signal to generate a low voltage control signal, and the operation switch is driven to be activated when the operation switch receives the second voltage control signal to generate a high voltage control signal; a voltage control end coupled with the operation switch, wherein the voltage control end generates a low voltage when the voltage control end receives the low voltage control signal, and the voltage control end generates a bias voltage when the voltage control end receives the high voltage control signal; and an output switch coupled with the voltage control end, wherein the output switch is driven to be deactivated when the output switch receives the low voltage of the voltage control end to determine that an output voltage is the same as the low voltage, and the output switch is driven to be activated when the output switch receives the bias voltage of the voltage control end to determine that the output voltage is the same as a high voltage.
