摘要：
Provided is a coordinate measuring device for sensing a location of a coordinate indicating device including a resonance circuit. The coordinate measuring device includes a panel including a plurality of channel electrodes configured to transmit a driving signal to the coordinate indicating device through capacitive coupling with the coordinate indicating device and receive a resonance signal generated by the coordinate indicating device, wherein the coordinate indicating device resonates based on the driving signal; and a controller configured to sense at least one of a frequency and a phase of the resonance signal and adjust the driving signal according to the at least one of the frequency and the phase, which is sensed.
