Abstract
Multiple sensor electrodes are formed such that they overlap a display panel, and each have an electrostatic capacitance that changes according to the user'"'"'s touch. Furthermore, a proximity sensor electrode pair is formed as a transparent electrode such that they overlap the display panel. An electrostatic capacitance detection circuit detects change in the electrostatic capacitance of each sensor electrode due to the user'"'"'s touch, thereby detecting a position touched by the user. A proximity detection circuit detects change in the electric field generated between the proximity sensor electrode pair due to the proximity of the user, thereby detecting the proximity of the user to the display panel. An electrostatic capacitance detection circuit is configured to have at least a component that is switchable between an operating state and a non-operating state. When detecting that the user is in proximity, this component transits from the non-operating state to the operating state.
