Abstract: An electronic device includes a display layer, a sensor layer, and a sensor driver that receives a sensitivity value from a node defined in an area where one electrode intersects one cross electrode, and calculates an input coordinate based on the sensitivity value. When the sensitivity value received from the node is equal to or greater than a first threshold value, the sensor driver calculates the input coordinate based on the sensitivity value. When each of a plurality of sensitivity values received from the node and a plurality of peripheral nodes adjacent to the node is less than the first threshold value and greater than or equal to a second threshold value, the sensor driver calculates the input coordinate based on the plurality of sensitivity values.
