Electronic device

An electronic device comprising:

• a sensor layer;
• and
• a sensor driver driving the sensor layer and selectively operating in a first mode for sensing a touch input and in a second mode for sensing a pen input,
• wherein the sensor layer includes:
• a plurality of first electrode groups arranged along a first direction;
• a plurality of second electrode groups arranged along a second direction crossing the first direction, the plurality of second electrode groups crossing the plurality of first electrode groups, and including at least one (2-1)-th electrode group and at least one (2-2)-th electrode group spaced apart from each other in the second direction;
• a first crossing trace line connected to one side of the at least one (2-1)-th electrode group;
• and
• a second crossing trace line connected to one side of the at least one (2-2)-th electrode group, the one side of the at least one (2-1)-th electrode group and the one side of the at least one (2-2)-th electrode group are opposite to each other with respect to the first direction,
• wherein a plurality of coupling capacitances are defined between adjacent (2-1)-th and (2-2)-th electrode groups, the plurality of coupling capacitances increasing a current sensing the pen input that is received by the sensor driver from the sensor layer in the second mode to increase a sensitivity of the sensing of the pen input.
