Claim 11:
12. An operation method of a touch device with the FPR function, wherein the operation method comprises:
controlling, by a plurality of first shift register circuits, a plurality of first switch sets according to a first clock signal, a plurality of first reset signals and a plurality of first control signals respectively, wherein the first switch sets are coupled to a plurality of transmitting electrodes to transmit a first signal, wherein one of the plurality of first switch sets comprises a plurality of first switches, and the plurality of first switches are coupled in parallel between the transmitting electrodes and one of the plurality of first shift register circuits; and
controlling, by a plurality of second shift register circuits, a plurality of second switch sets according to a second clock signal, a plurality of second reset signals and a plurality of second control signals, wherein the second switch sets are coupled to a plurality of receiving electrodes to receive a second signal, wherein the plurality of second shift register circuits are controlled by the plurality of second control signals which are different from each other,
wherein the first signal and the second signal are for a touch operation and a FPR operation,
wherein in the touch operation, the first switch sets are controlled by the first reset signals and the second switch sets are controlled by the second reset signals, and the first clock signal and the second clock signal have disable levels, and
wherein in the FPR operation, the first switch sets are controlled by the first clock signal and the second switch sets are controlled by the second clock signal, and the first reset signals and the second reset signals have disable levels.
