High-efficiency fingerprint identification device
Abstract:
A high-efficiency fingerprint identification device includes an electrode substrate, plural 1-to-N switch circuits formed on the electrode substrate, plural sensing electrodes and plural wires. Each 1-to-N switch circuit has one first end, N second ends and m control ends. The m control ends control connection between the N second ends and the first end. Each sensing electrode corresponds to a nearby 1-to-N switch circuit. The wires are divided into sensing and driving lines and control lines. The sensing electrodes in each column correspond to a sensing and driving line. The sensing and driving line is connected to one of the N second ends of the 1-to-N switch circuits in the column. The sensing electrodes in each row correspond to m control lines. Each control line is connected to ones of the m control ends of the 1-to-N switch circuits in the row.
