Electronic device including integrated touch fingerprint sensor, operation method thereof, and recording medium

Abstract

An electronic device is provided. The electronic device includes a display in which a plurality of pixels are arranged, a display driver integrated circuit (IC) configured to control an operation of the display, a touch fingerprint sensor disposed inside the display and including transmit (Tx) lines and receive (Rx) lines formed of a metal mesh, a touch fingerprint sensor IC configured to control an operation of the touch fingerprint sensor, one or more processors configured to control operations of the display driver IC and the touch fingerprint sensor IC, and memory operatively connected to the one or more processors, wherein the memory store one or more computer programs, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors during a touch sensing operation, cause the electronic device to configure a plurality of Tx touch channels by grouping the Tx lines in a predetermined number of units, and supply a first Tx signal to the plurality of Tx touch channels, configure a plurality of Rx channels by grouping the Rx lines in a predetermined number of units, and receive a first Rx signal of each of the plurality of Rx channels, and detect a touch location, based on the first Rx signal of each of the plurality of Rx channels.
