Claim 0:
1. A touch device with a fingerprint recognition (FPR) function, comprising:
a plurality of sensing regions comprising transmitting electrodes and receiving electrodes;
a plurality of first switch sets coupled to the transmitting electrodes and to transmit a first signal;
a plurality of first shift register circuits to control the first switch sets according to a first clock signal, a plurality of first reset signals and a plurality of first control signals respectively, 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;
a plurality of second switch sets coupled to the receiving electrodes and to receive a second signal; and
a plurality of second shift register circuits to control the second switch sets according to a second clock signal, a plurality of second reset signals and a plurality of second control signals, wherein the plurality of second control signals 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.
