Abstract
A full-screen electronic device with a fingerprint sensing function and a fingerprint sensing method are provided. The full-screen electronic device includes a panel module, a plurality of fingerprint sensors and a control unit. The plurality of fingerprint sensors are aligned with the panel module and distributed into a plurality of scan regions in an array. The fingerprint sensing method includes the following steps. Firstly, a concerned information about a concerned position of the display panel is generated. After the control unit receives the concerned information, the control unit defines the scan regions of the concerned position as a first scan set according to the concerned information. Then, the control unit controls the fingerprint sensors corresponding to the first scan set according to a first scan strategy.
