Electronic device

An electronic device comprising:

• a display layer configured to display an image, the display layer comprising:
• a plurality of data lines;
• and
• pixels each connected to a corresponding data line among the plurality of data lines;
• a display driver configured to output data signals to the plurality of data lines;
• a sensor layer on the display layer, the sensor layer comprising a plurality of first electrodes, a plurality of second electrodes, and a guard signal line;
• and
• a sensor driver configured to drive the sensor layer,
• wherein the plurality of first electrodes comprises electrodes of a first group and electrodes of a second group, and
• wherein the sensor driver is configured to:
• output transmission signals to the electrodes of the first group;
• output at least one compensation signal to the electrodes of the second group or the guard signal line;
• and
• receive detection signals from the plurality of second electrodes.
