Abstract:
1. A method of detecting floating mode of a touch panel, comprising steps of: (a) reading a sensing cluster having multiple sensing points and presetting a detection window; (b) taking each sensing point of the sensing cluster as a center point of the detection window to perform scanning; (c1) determining whether the center point has a negative sensing value less than a first floating margin, when positive, proceeding step (c2) (c2) determining a count of other sensing points in the detection window having the sensing values greater than a first grounding margin, incrementing an accumulative number by one when the count exceeds a first critical value; (d) repeating step (c1) until all the sensing points in the sensing cluster have been taken as the center point of the detection window for scanning; and (e) when the accumulative number is greater than a second critical value, determining the current sensing cluster is generated under a floating mode.
