Abstract
A pressure sensing assembly integrated with a fingerprint identification function includes a pressure sensing unit and a control unit. The pressure sensing unit includes a plurality of pressure sensing sub-units arranged in N rows and M columns, a pressure sensing processing sub-unit, and a fingerprint identification processing sub-unit, where N and M are each a positive integer. A pressure sensing sub-unit in an nth row and an mth column includes a pressure sensing module in the nth row and the mth column and a fingerprint identification module in the nth row and the mth column. The pressure sensing processing sub-unit and the fingerprint identification module in the nth row and the mth column are connected to the control unit, where n is a positive integer smaller than or equal to N, and m is a positive integer smaller than or equal to M. The control unit is configured to, upon the receipt of a pressure sensing indication signal, transmit a fingerprint identification control signal to the fingerprint identification module in the nth row and the mth column.
