Abstract: A sensing unit includes a base, first electrodes, an insulating layer, second electrodes, and third electrodes. The first electrodes are arranged on the base, extend in a first direction, and are spaced apart from each other in a second direction different from the first direction. The first insulating layer is disposed on the first electrodes. The second electrodes are electrically insulated from the first electrodes by the insulating layer, extend in the second direction, and are spaced apart from each other in the first direction. The third electrodes are electrically insulated from the first electrodes by the insulating layer, extend in the second direction, and are electrically insulated from the second electrodes. The second electrodes and the third electrodes are alternately arranged in the first direction. The third electrodes may receive a driving signal or a sensing signal according to a sensing mode.
