Abstract
An electronic device includes a sensor layer including a plurality of first electrodes and a plurality of second electrodes, a sensor driving circuit driving the sensor layer and operating in a first or second mode, and a main driving circuit controlling an operation of the sensor driving circuit. In the first mode, the sensor driving circuit outputs a plurality of first transmit signals to the plurality of first electrodes respectively, receives a plurality of first sensing signals from the plurality of second electrodes respectively, and outputs the plurality of first sensing signals to the main driving circuit. In the second mode, the sensor driving circuit outputs a plurality of second transmit signals to the plurality of first electrodes respectively, receives a plurality of second sensing signals from the plurality of second electrodes respectively, and provides the main driving circuit with a coordinate based on the plurality of second sensing signals.
