Abstract

The present application provides an electronic device comprising an operational circuit, which is temporarily closed when the electronic device is in a sleep mode; a display screen having a light emitting area; a plurality of fingerprint sensing pixel units located in the light emitting area; and a fingerprint identification circuit coupled to the plurality of fingerprint sensing pixel units. The display screen emits light in the light emitting area when the electronic device is in the sleep mode, and the display screen does not emit light in addition to the light emitting area.

Description

technical field [0001] The present application relates to an electronic device, in particular to an electronic device that can guide a user to press his finger in a sleep mode. Background technique [0002] With the rapid development of technology, more and more portable electronic devices such as mobile phones, digital cameras, tablet computers, and notebook computers have become necessary tools in people's lives. Because portable electronic devices are generally used by individuals and have a certain degree of privacy, the data stored in them, such as phonebooks, photos, personal information, etc., are privately owned. Once the electronic device is lost, the data may be used by others, causing unnecessary losses. Although there is currently a password protection method to prevent the electronic device from being used by others, the password is easy to leak or be cracked, and has low security. Moreover, the user needs to remember the password to use the electronic device....
