Display device

An electronic device, comprising:

• a control circuit, configured to switch between a first touch sensing mode of the electronic device and a second touch sensing mode of the electronic device;
• and
• a plurality of sensing units, electrically connected to the control circuit,
• wherein a first amplitude of a first touch driving signal provided by the control circuit operating in the first touch sensing mode is smaller than a second amplitude of a second touch driving signal provided by the control circuit operating in the second touch sensing mode,
• wherein the control circuit in the first touch sensing mode groups the sensing units into a first sensing unit group and a plurality of second sensing unit groups,
• wherein in the first touch sensing mode, when triggering behavior is sensed, the control circuit controls the electronic device to enter the second touch sensing mode and restores the first sensing unit group and the second sensing unit groups back to the sensing units,
• wherein the first touch sensing mode is a mutual-capacitance sensing mode, and
• wherein the second touch sensing mode is a self-capacitance sensing mode.
