Abstract: A touch sensor that may detect an object away from the sensor is provided. The touch sensor includes one or more drive electrodes; one or more detection electrodes forming capacitance in cooperation with the respective drive electrodes; a detection circuit applying drive signals to the respective drive electrodes to detect the object based on detection signals obtained from the respective detection electrodes in response to the respective drive signals; and a controller controlling to change a range of electric flux lines generated between the drive electrodes and the detection electrodes.
