Abstract
A stylus control circuit used to control a stylus includes a positioning signal generator. The positioning signal generator is used to generate a first positioning signal having a first frequency and transmit the first positioning signal to the stylus through a first positioning transmission electrode. Wherein, the first frequency corresponds to a position of the first positioning transmission electrode, and the first positioning signal is a frequency signal without carrying any digital data.
