Claim 0:
1. 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 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 first ends of sensing electrodes directly adjacent to each other among the sensing electrodes; and
a second sensing line connecting at least one of second ends, which are opposite to the first ends, of the directly adjacent sensing electrodes to the driving circuit, and selectively connecting other sensing electrodes to the at least one of second ends or a reference electric potential in response to the control signal,
wherein a first input of the charge amplifier is electrically connected to the directly adjacent sensing electrodes in the touch mode, and
wherein the first input of the charge amplifier is electrically connected to at least one of the directly adjacent sensing electrodes and a second input of the charge amplifier is electrically connected to the other sensing electrodes in the pen sensing mode.
