  • Electronic device using under-display fingerprint identification technology and waking method thereof
    Patent number: 11100891
    Abstract: An electronic device using an under-display fingerprint identification technology and a waking method of the electronic device are provided. The electronic device includes a display panel, a central processing unit and a fingerprint sensing module. The electronic device executes an operating system. When the central processing unit and the operating system are in a power-saving mode, the fingerprint sensing module enters a default operation mode and the display panel enters an always-on display mode. Then, the fingerprint sensing module senses a specified region of the display panel to acquire a first image. If the content of the first image contains an image of a finger, the fingerprint sensing module issues an interrupt signal to the central processing unit. Consequently, the central processing unit is woken up from the power-saving mode and the operating system is woken up.
