Abstract
An electronic device is provided. The electronic device includes a sensor layer including a first channel including one or more first electrodes and a second channel including one or more second electrodes and a control circuit configured to detect touch information corresponding to an input of an external object to the sensor layer based on a change in capacitance between at least one of the one or more first electrodes and at least one of the one or more second electrodes and detect pressure information corresponding to the input based on a resistance changed by the input to at least one of the first channel or the second channel.
