Abstract
The present disclosure relates to a touch technology field, provides a touch detecting method for a touch sensor, the method comprises the following steps: putting the touch sensor into a mutual capacitance mode and a self capacitance mode alternatively, and scanning and detecting the rows and columns of a capacitance array of the touch sensor; when a touch state is preliminarily judged as no touch according to a scanning and detecting result in the mutual capacitance mode, implementing envelopment analysis for data obtained by sampling in the self capacitance mode and determining whether the touch exists in the mutual capacitance mode, updating no reference in the mutual capacitance mode if the touch exists, and updating the reference in the mutual capacitance mode if no touch exists.
