Abstract
An active stylus pen comprises a touch component and a pressure sensing module. One end of the touch component is disposed at a nib part of the active stylus pen, wherein the touch component is configured to receive an external pressure. The pressure sensing module is connected to the touch component, wherein the pressure sensing module is configured to generate an oscillation signal, wherein the oscillation signal has a first frequency when the touch component receives the external pressure and the external pressure reaches a first threshold value, and wherein the oscillation signal is adjusted to have a second frequency when the touch component receives the external pressure and the external pressure does not reach the first threshold value; wherein a difference of the first frequency and the second frequency is larger than a second threshold value.
