Abstract
An apparatus for implementing touch control and fingerprint identification includes: a fingerprint identification sensor including a plurality of sub-sensors and configured to transmit a signal generated by detection of a plurality of sub-sensors to a fingerprint identification circuit when a combination switch is open circuited, and to combine the signal generated by the detection of the plurality of sub-sensors into a touch signal and transmit the touch signal to a touch control circuit when the combination switch is closed. The fingerprint identification circuit is configured to process the signal generated by the detection of the plurality of sub-sensors; and the touch control circuit is configured to determine presence of a touch operation according to the combined touch signal. Accordingly, the functions of fingerprint identification and touch control can be implemented by sharing a fingerprint identification sensor, so that integration level of an electronic device is improved.
