Abstract:
An electronic device with fingerprint sensing function including a fingerprint sensing array, multiple fingerprint sensing signal readout lines, multiple touch driving lines, a touch driving circuit, and a read circuit is provided. The fingerprint sensing array includes multiple fingerprint sensing units arranged in array. The fingerprint sensing signal readout lines are respectively coupled to a column of fingerprint sensing units of the fingerprint sensing array. The touch driving lines are respectively interleaved with the fingerprint sensing signal readout lines. The touch driving circuit is coupled to the touch driving lines, and provides multiple touch driving signals to the touch driving lines. The read circuit is coupled to the fingerprint sensing signal readout lines. In response to the touch driving lines outputting the touch driving signals, the read circuit determines a touch position of a touch object based on multiple read signals output by the fingerprint sensing signal readout lines.
