Abstract
A sensor device includes a sensor array including a plurality of sensor nodes, signal lines electrically connected to the plurality of sensor nodes, and a sensor driver configured to sense a user's touch of the sensor array by selecting the plurality of sensor nodes through the signal lines, apply a first pulse signal having a same phase as a target pulse signal of a selected sensor node to at least one first sensor node adjacent to the selected sensor node among the plurality of sensor nodes, and apply a second pulse signal having a phase opposite to that of the first pulse signal to at least one second sensor node among the plurality of sensor nodes. The sensor driver sets at least one sensor node adjacent to or spaced apart from the first sensor node as the second sensor node according to a preset mode.
