Abstract
A method of detecting floating mode of a touch panel has steps of reading a sensing cluster and presetting a detection window; taking each sensing point of the sensing cluster as a center point of the detection window; after determining that the center point has a negative sensing value qualifying to be generated under a floating mode, further determining a count of the sensing points other than the center point having the sensing values generated under a grounding mode and incrementing an accumulative number by one if the count exceeds a first critical value; keeping incrementing the accumulative number until each sensing point in the sensing cluster has been taken as the center point of the detection window for scanning; and determining if the accumulative number exceeds a second critical value, and if positive, further determining that the current sensing cluster is generated under the floating mode.
