Abstract

An electronic circuit for operating with a display panel including touch sensors and fingerprint sensors is provided. The electronic circuit includes a first circuit, a second circuit, a third circuit, a first switch circuit and a control circuit. The first circuit generates display driving signals for driving the display panel. The second circuit receives fingerprint sensing signals from the fingerprint sensors. The third circuit determines a touch information according to touch sensing signals from the touch sensors. The first switch circuit includes a plurality of first switch units, each of the first switch units includes a first switch element and a second switch element. The control circuit controls the first switch circuit to transmit the display driving signals in a first time interval, controls the first switch circuit to transmit the fingerprint sensing signals in a second time interval, and controls the third circuit to receive the fingerprint sensing signals in a third time interval.
