FINGERPRINT RECOGNITION DEVICE FOR CAPACITANCE SENSING, USING DRIVER HAVING PIPELINE SCAN STRUCTURE

摘要

A fingerprint recognition device for capacitance sensing according to an embodiment of the present invention may comprise: a fingerprint sensor cell array including a plurality of cells, which are connected to a plurality of row lines and a plurality of column lines, respectively; a plurality of column line sets including a predetermined number of column lines out of the fingerprint sensor cell array; a variable cycle clock generating unit, which can operate a pipeline process performed for each column line included in the column line set; and a multi-column line selecting unit for selecting one column line from among the column lines of the cell array, wherein the variable cycle clock generating unit may sequentially control an integral action executed on each column line included in the column line set, at different times.
