Abstract: A fingerprint sensing device comprises a plurality of sensing pads, a plurality of data lines, a shielding layer, and a plurality of auxiliary voltage lines. The data lines are separately and electrically connected to the sensing pads, and configured to provide a sensing voltage to the sensing pads. The shielding layer is disposed between the sensing pad and the data lines. The auxiliary voltage lines are separately and electrically connected to the sensing pads, configured to provide an auxiliary voltage to the sensing pads. The auxiliary voltage is different from the sensing voltage. When a first sensing pad receives the sensing voltage, a second sensing pad adjacent to the first sensing pad receives the auxiliary voltage.

Abstract: A touch sensing circuit and its control method is disclosed herein. The touch sensing circuit includes a plurality of detecting units. The detecting units are arranged in an array, in which each detecting unit includes a sensing pad, a first switch and a second switch. The first switch is configured to selectively conduct the sensing pad and one of a plurality of signal lines. The second switch is configured to selectively conduct two adjacent sensing pads. When the first switches in a first row in the array are on, the sensing pads in the first row are configured to output detecting signals to the signal lines according to a driving signal, and the second switches in a second row adjacent to the first row are on to conduct the sensing pads in the second row to receive and transmit the driving signal together.

Abstract: A sensing method of a fingerprint sensor is provided. The fingerprint sensor includes a plurality of sensing pixels arranged in an array, and the sensing pixels respectively have a sensing electrode. The sensing method includes following steps. A required resolution of an identification requirement is determined; here, the identification requirement is received by the fingerprint sensor. If the number of pixels of the required resolution is less than or equal to the number of the sensing pixels, self-capacitance sensing is performed on the sensing pixels to provide a first fingerprint pattern. If the number of pixels of the required resolution is greater than the number of the sensing pixels, the self-capacitance sensing and mutual capacitance sensing are performed on the sensing pixels to provide a second fingerprint pattern.
