Abstract
A signal generating circuit of an active pen (), an active pen and a signal driving method are disclosed. The signal generating circuit includes a power source unit () and a control unit (), the power source unit () is configured to supply a signal driving voltage to the active pen, and the control unit () is configured to control alternate generation of a positive voltage and a negative voltage between a pen tip and a pen casing of the active pen in case where the power source unit only generates a single voltage. The signal generating circuit (), the active pen and the signal driving method can reduce a signal driving power consumption of the active pen while ensuring a signal driving effect.
