Abstract

The invention provides a fingerprint identification method and a mobile terminal. The method comprises the following steps: if a touch operation on the screen of the mobile terminal is detected, identifying the touch area of the touch operation on the screen of the mobile terminal; if a detection result shows that the mobile terminal is under a state that a fingerprint is to be authenticated, controlling the luminance value of the touch area to be greater than or equal to a first preset luminance value, and controlling the luminance value of the display area except the touch area on the screenof the mobile terminal to be smaller than the first preset luminance value; utilizing a fingerprint identification module to collect and identify the fingerprint information of the touch area. Through the fingerprint identification method provided by the invention, the power consumption of the mobile terminal can be lowered while a high fingerprint identification rate is guaranteed, and the endurance time of the mobile terminal is prolonged.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a fingerprint identification method and a mobile terminal. Background technique [0002] As the size of the display screen of the mobile terminal becomes larger and various application scenarios with high power consumption continue to increase, it becomes more and more important to reduce the power consumption of the mobile terminal and improve the battery life of the mobile terminal. At present, many mobile terminals have a fingerprint identification function, and the user's fingerprint information is collected by a fingerprint identification module for identification, so as to authenticate the user's identity. In order to facilitate users to use the fingerprint recognition function, an under-screen photoelectric fingerprint recognition technology has been produced. The principle is that when a finger touches the screen, the display is highlighted. After the light is refl...
