Abstract

The present invention provides a fingerprint identification method and a mobile terminal. When a user touches a touch screen, an induced voltage is generated based on light energy reflected by the user's finger, and the light is light emitted by two adjacent pixels; The color combination of light emitted by each pixel; based on the pre-established correspondence between the color combination and the dynamic gain parameter, determine the dynamic gain parameter of the amplifier corresponding to the color combination; based on the induced voltage and the dynamic gain parameter, generate a fingerprint recognition image ; Perform fingerprint recognition based on the fingerprint recognition image. Therefore, when the mobile terminal realizes the fingerprint identification function, the mobile terminal can realize multi-color display, thereby ensuring the display effect of the 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] At present, the use of screen fingerprint recognition functions on mobile terminals is becoming more and more common, such as unlocking and payment. [0003] Such as figure 1 , 2 As shown, when the mobile terminal user’s finger touches the fingerprint recognition area of ​​the mobile terminal touch screen, the light emitted by the touch screen is reflected by different optical paths of the peaks and troughs of the user’s fingerprint, and then passes between adjacent pixels of the touch screen. The set light receiving hole is received by the light fingerprint recognition module set on the touch screen, thereby forming a fingerprint recognition image, and finally realizes the screen fingerprint recognition function through a corresponding algorithm. ...
