Claim 19:
20. An electronic device, comprising:
a display panel;
an input sensor disposed on the display panel, and selectively operating in a pen sensing mode or a touch mode; and
a driving circuit that drives the input sensor, and comprises a charge amplifier,
wherein the input sensor comprises:
a first sensing electrode;
a second sensing electrode directly adjacent to the first sensing electrode;
a first line directly electrically connecting the first sensing electrode to the second sensing electrode; and
a second line selectively connecting the second sensing electrode to the first sensing electrode or a reference electric potential,
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.
