Abstract

The embodiment of the invention provides a fingerprint identification method and a mobile terminal, which relate to the technical field of communication, so as to solve the problem that the power consumption caused by the mobile terminal misstart fingerprint identification due to frequent mistouch of a screen by a user. The fingerprint identification method comprises the following steps: when themobile terminal is in a standby state, if a touch operation of a user on a screen is detected, acquiring a first touch area of the screen touched by the user; and when the mobile terminal is in a standby state, acquiring a first touch area of the screen touched by the user; acquiring and identifying fingerprint information of the first touch area if the first touch area satisfies a graphical characteristic parameter of preset fingerprint information. The fingerprint identification method in the embodiment of the invention is applied to a mobile terminal.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a fingerprint identification method and a mobile terminal. Background technique [0002] With the continuous improvement of people's requirements, the screens of mobile terminals are getting bigger and bigger, especially now that full-screen mobile terminals have appeared. In order to improve user experience, common full-screen mobile terminals are realized by a rear-mounted fingerprint unlock chip. Fingerprint unlock function. [0003] With the development of fingerprint recognition technology, in order to further satisfy users, the fingerprint recognition technology under the screen gradually appeared. The fingerprint recognition technology under the screen refers to setting a fingerprint recognition chip under the screen, and obtaining the user's fingerprint through the photoelectric information generated by the user touching the screen....
