CONTROL METHOD AND ELECTRONIC STYLUS FOR TOUCH INPUT TO A CAPACITIVE TOUCHPAD MODULE |
摘要 |
An electronic stylus emits an excitation signal to apply to a trace of a capacitive touchpad module near a touch point when the electronic stylus touches the capacitive touchpad module, so as to change a waveform of a charging/discharging signal in the trace, and depending on the waveform variation, the capacitive touchpad module can identify the touch point. |
