A controlling system and a controlling method of a touch panel, and a stylus pen for applying to the touch panel

摘要

A controlling system of a touch panel comprises of a drive signal generating circuit, a sensing module for sensing a waveform signal from the touch panel, and a signal processing module for enabling and disabling the drive signal generating circuit based on the signal outputted by the sensing module. Therefore, the mentioned controlling system can support the active and the passive touch modes. In addition, the present invention further provides a controlling method of the touch panel and a stylus pen applied to the mentioned controlling system.
