Abstract: A detection apparatus includes a first substrate, a first electrode, a plurality of second electrodes, a detection controller, and a second electrode controller. The first electrode is disposed on the first substrate. The second electrodes have an area smaller than the area of the first electrode and overlap the first electrode. The detection controller is coupled to the first electrode and detects a detection signal corresponding to a capacitance change in the first electrode. The second electrode controller supplies, to some of second electrodes in the second electrodes, a guard signal for suppressing a capacitance change in overlapping areas of the first electrode overlapping the respective second electrodes.
