Zusammenfassung:The invention discloses a stylus control circuit and a stylus thereof, the stylus control circuit is used for controlling the stylus and comprises a positioning signal generator, the positioning signal generator is used for generating a first positioning signal with a first frequency, and the first positioning signal is used for generating a second positioning signal with a second frequency. And transmitting the first positioning signal to the stylus through a first positioning transmission electrode. Wherein the first frequency corresponds to the position of the first positioning transmission electrode, and the first positioning signal is a frequency signal which does not carry any digital data. 本发明公开了一种触控笔控制电路及其触控笔,所述触控笔控制电路用来控制触控笔,并包括一定位信号产生器,该定位信号产生器用来产生具有一第一频率的一第一定位信号,并通过一第一定位传输电极传送该第一定位信号至该触控笔。其中,该第一频率对应于该第一定位传输电极的位置,且该第一定位信号是未携带任何数字数据的一频率信号。
