Abstract
An electronic circuit adapted to drive a display panel including touch sensors and fingerprint sensors is provided. The electronic circuit includes a switch circuit and a control circuit. The switch circuit includes a plurality of first switch elements and a plurality of second switch elements. The control circuit is configured to generate control signals for controlling the switch circuit, so as to control the electronic circuit to transmit the display driving signals from the first circuit to the data lines through a first part of the first switch elements in a first time interval, and control the electronic circuit to receive the fingerprint sensing signals from the fingerprint sensors of the display panel through the second switch elements in a second time interval.
