Claim 13:
14. An electronic device, comprising:
a display panel;
an input sensor disposed on the display panel, comprising a plurality of sensing electrodes and a plurality of sensing lines connected to the sensing electrodes, and selectively operating in a pen sensing mode or a touch mode; and
a driving circuit that drives the input sensor, generates a first control signal or a second control signal based on a type of input applied to the input sensor, and comprises a charge amplifier,
wherein the sensing lines comprise:
a first sensing line directly electrically connecting a first end of a first sensing electrode and a first end of a second sensing electrode directly adjacent to the first sensing electrode among the sensing electrodes; and
a second sensing line comprising a switch connecting a second end of the first sensing electrode to the driving circuit, connecting the second sensing electrode to the first sensing electrode when the first control signal is provided, and connecting the second sensing electrode to a reference electric potential when the second control signal is provided,
wherein a first input of the charge amplifier is electrically connected to the first sensing electrode and the second sensing electrode in the touch mode, and
wherein the first input of the charge amplifier is electrically connected to the first sensing electrode and a second input of the charge amplifier is electrically connected to the second sensing electrode in the pen sensing mode.
