Abstract

An interface device includes an electronic device and an input device for communicating with the electronic device, wherein the electronic device includes a display layer, a sensor layer which is disposed on the display layer and senses a first input by the input device, a display driving unit for generating a vertical synchronization signal for driving the display layer, and a control unit for controlling the sensor layer, wherein the control unit outputs, in synchronization with a first vertical synchronization signal, a first uplink signal to the sensor layer and outputs, in synchronization with a second vertical synchronization signal, a second uplink signal having a phase different from a phase of the first uplink signal to the sensor layer.
