Abstract
A sensing apparatus includes a substrate, N groups of sensing elements formed on the substrate, a sensing circuit and a switch control circuit. Each group of the N groups of sensing elements includes a plurality of sensing elements. Each of the sensing elements includes a thin-film transistor (TFT) switch and a sensing electrode. The sensing electrode drives the N groups of sensing elements to sequentially generate N groups of sensing signals. By controlling the TFT switches, the switch control circuit controls a plurality of sensing electrodes included in one group of the N groups of sensing elements to be coupled to the sensing circuit.
