Abstract: An electronic device including: a display layer; a sensor layer disposed on the display layer; a memory configured to store first sensitivity values and first differential sensitivity values; and a sensor driver configured to calculate second sensitivity values from a plurality of nodes and to calculate second differential sensitivity values, wherein the sensor driver is configured to: calculate difference values between the first differential sensitivity values and the second differential sensitivity values; calculate a first average value of a first row or column of values among the difference values; and calculate a second average value of remaining values among the difference values, wherein the remaining values were not used in the first average value calculation, and wherein the sensor driver determines whether to update a baseline, based on the first average value and the second average value.
