Abstract

The invention provides a fingerprint identification scanning method and a mobile terminal and relates to the technical field of electronics. The method solves the problems that the unlocking speed ofa bezel-less screen fingerprint identification mode in the prior art is low, and the power consumption is large. The method is applied to the mobile terminal, and a fingerprint identification sensor is arranged below a touch screen of the mobile terminal. The method includes the steps of obtaining the corresponding scanning frequency of each fingerprint identification area on the touch screen; controlling the fingerprint identification sensor to carry out fingerprint identification scanning on each fingerprint identification area according to the corresponding scanning frequency of the fingerprint identification area. According to the scheme, fingerprint identification scanning is conducted in different areas of the touch screen, the scanning speed is increased, the unlocking speed is increased, and through differential processing on each fingerprint identification area of the touch screen, fingerprint identification scanning can be conducted in each area according to different scanning frequencies without conducting fast scanning according to a high frequency on the whole touch screen, so that the power consumption is lowered, and the electric quantity is saved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a scanning method for fingerprint identification and a mobile terminal. Background technique [0002] The current fingerprint identification method used on mobile phones can only be identified in a specific part of the area, usually the home button of the mobile phone or a specific area on the back of the battery cover. The identification area is narrow, which is very inconvenient and requires additional space, which affects the appearance. and mobile phone layout space. The full-screen fingerprint recognition method can solve this problem. It sets the fingerprint recognition sensor under the touch screen, and it can be unlocked when the finger touches any position of the touch screen. The advantage of the full-screen fingerprint recognition method is that it is convenient and the appearance of the mobile phone is beautiful, but the disadvantage is that the unlocking speed i...
