Abstract

Embodiments of the present invention provide a method for controlling a fingerprint identification module and a mobile terminal. The method includes: when the user touches the fingerprint identification module, detecting whether the fingerprint identification module is in the Home button mode; When the fingerprint identification module is in the Home key mode, control the fingerprint identification module to work using the first scanning frequency and the first capacitance threshold; when the fingerprint identification module is not in the Home key mode, control the The fingerprint identification module works with a second scanning frequency and a second capacitance threshold, wherein the second scanning frequency is greater than the first scanning frequency, and the second capacitance threshold is smaller than the first capacitance threshold. The embodiment of the invention can be used to prevent the fingerprint identification module from being accidentally touched.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a method for controlling a fingerprint identification module and a mobile terminal. Background technique [0002] With the rapid development of information technology, the use of mobile terminals (such as mobile phones, tablet computers, etc.) is becoming more and more popular. As a standard technology for mobile terminals, fingerprint recognition technology has been widely used on mobile terminals. [0003] In the prior art, as far as the touch-type fingerprint recognition module is concerned, the mobile terminal is not equipped with a Home button on the hardware, and the function of the Home button is simulated on the software by the fingerprint recognition module, because the fingerprint recognition module is generally It cannot be pressed but can only be touched. Therefore, this kind of fingerprint recognition module that needs to bear the functions of fingerprint and Home...
