PROBLEM TO BE SOLVED: To provide a stylus, a pressure detecting system and a driving method thereof.SOLUTION: Provided is a stylus comprising: a pressure detector for detecting applied pressure; a first signal generator for generating a signal of a first frequency; a second signal generator for generating a signal of a second frequency; and a controller for controlling at least one of the signal generators to adjust the amplitude ratio of the signal of the first frequency to the signal of the second frequency according to the pressure detected by the pressure detector. Also provided are a pressure detecting system and a driving method thereof. According to this invention, writing pressure of the stylus can be easily detected without changing the frequency of the signal emitted from the stylus. |
