Display Device Provided With Touch Sensor, Electronic Apparatus Using Same, And Control Circuit Of Display Module Provided With Touch Sensor

A control circuit for a display module furnished with a touch sensor, wherein the display module comprises:

• a display panel;
• a plurality of sensor electrodes formed in a region where they overlap the display panel, and each having an electrostatic capacitance that changes according to a state of being touched by a user;
• and a proximity sensor electrode pair comprising an electric field generating electrode and an electric field detection electrode each formed as a transparent electrode in a region where they overlap the display panel, and configured to generate an electric field between these two electrodes,
• and wherein the control circuit comprises an electrostatic capacitance detection circuit configured to detect change in the electrostatic capacitance that occurs at each of the plurality of sensor electrodes so as to detect a position touched by a user, and comprising at least a component that is switchable between an operating state and a non-operating state,
• and wherein the electrostatic capacitance detection circuit is connected to a proximity detection circuit configured to detect the user being in proximity to the display panel by monitoring change in the electric field generated between the proximity sensor electrode pair,
• wherein said at least one component of the electrostatic capacitance detection circuit is configured to switch from the non-operating state to the operating state upon detection by means of the proximity detection circuit that the user is in proximity thereto.
