Abstract
An apparatus for implementing touch control and fingerprint identification includes: a fingerprint identification sensor, a fingerprint identification circuit, a combination switch and a touch control circuit. The fingerprint identification sensor comprises a plurality of sub-sensors. The fingerprint identification sensor transmits a signal generated by detection of the plurality of sub-sensors to the fingerprint identification circuit when the combination switch is open circuited, and combines the signal generated by detection of the plurality of sub-sensors into a touch signal through the combination switch so as to transmit the touch signal to the touch control circuit when the combination switch is closed.
