Abstract
A signal detecting method for a touch panel, a touch panel, and a display device are disclosed. The touch panel includes: several driving lines, several sensing lines, several driving electrodes, and several sensing electrodes; and also includes: a driving module configured to provide driving signals to the respective driving electrodes to drive the respective driving electrodes; a first detection module configured to detect a first signal representing a capacitance between a particular driven driving electrode and each of the sensing electrodes; a reusing module configured to, when one of the driving electrode is driven, reuse at least one driving electrode other than the driven driving electrode to additionally function as a sensing electrode; and a second detection module configured to detect a second signal representing a capacitance between the driven driving electrode and the at least one reused driving electrode which additionally functions as a sensing electrode.
