Electronic device

An electronic device comprising:

• a sensor layer configured to be folded or unfolded about a folding axis extending in a first direction;
• and
• a sensor driver configured to drive the sensor layer by selectively operating in a first mode to sense a touch input, a second mode to sense a pen input, or a third mode to sense a folding of the sensor layer,
• wherein the sensor layer comprises:
• a plurality of first electrodes along the first direction;
• a plurality of second electrodes along a second direction crossing the first direction;
• a first electrode group comprising a plurality of first auxiliary electrodes along the second direction;
• a first auxiliary trace line electrically connected with the plurality of first auxiliary electrodes;
• a first signal transmission line electrically connected with a first-first auxiliary electrode among the plurality of first auxiliary electrodes;
• and
• a second signal transmission line electrically connected with a first-second auxiliary electrode spaced from the first-first auxiliary electrode in the second direction among the plurality of first auxiliary electrodes, and
• wherein in the third mode, the sensor driver is configured to provide a first signal to the first signal transmission line, and a second signal to the second signal transmission line, the second signal being an inverse signal of the first signal.
