FINGERPRINT SENSOR WITH COLUMN READ-OUT

A fingerprint sensor comprising a plurality of sensing elements distributed across a rectangular sensing area with mutually opposite short sides and mutually opposite long sides, the sensing elements being arranged in a plurality of rows and a plurality of columns; readout circuitry arranged in a readout area located adjacent to a short side of the sensing area; and a plurality of readout lines for connecting each of the sensing elements to the readout circuitry, the readout lines in the plurality of readout lines extending in parallel to the long sides of the sensing area. For each column of sensing elements in the plurality of columns, at least a first sensing element and a second sensing element in the column are simultaneously connectable to the readout circuitry via a first readout line and a second readout line, respectively, in the plurality of readout lines.
