Touch calibration system and method thereof

A touch calibration method, applicable to a touch calibration system, for calibrating the touch calibration system under a calibration mode, the touch calibration system including a touch pad, a waveform generation module a counter, a first timer, and a storage module, wherein the waveform generation module is electrically connected to the touch pad, the counter is electrically connected to the waveform generation module, the first timer is electrically connected to the counter, the storage module is electrically connected to the first timer, and the method comprising:

• setting the counter with a fixed counter value
• generating, by the waveform generation module, at least an oscillating wave;
• counting, by the counter, an oscillation number of the oscillating wave generated by the waveform generation module and measuring, by the first timer, a calibrated oscillating time;
• determining whether the oscillation number reaches the fixed counter value;
• and
• if the determination of step (d) is yes, storing, in the storage module, the calibrated oscillating time measured by the first timer;
• wherein the calibration mode is defined as that the touch pad stops receiving a touch signal generated from a user.
