  • Method and apparatus for fingerprint identification and terminal device
    Patent number: 11048906
    Abstract: Embodiments of the present application provide a method for fingerprint identification, which could reduce power consumption generated in the process of fingerprint identification. The method includes: capturing an optical signal, where the optical signal includes an optical signal, in an illumination region of a display screen, illuminating on a finger and reflected by the finger, the illuminating region is determined according to a pressing region within a fingerprint capturing region in which the finger performs a fingerprint pressing operation, and an area of the illuminating region is smaller than an area of the fingerprint capturing region; and performing fingerprint identification according to the optical signal.

  • METHOD AND APPARATUS FOR FINGERPRINT IDENTIFICATION AND TERMINAL DEVICE
    Publication number: 20200265205
    Abstract: Embodiments of the present application provide a method for fingerprint identification, which could reduce power consumption of a display screen in a fingerprint identification process. The method including: acquiring a pressing region in which a finger performs a fingerprint pressing operation in a fingerprint capturing region; and determining an illuminating region of a display screen according to the pressing region, where light emitted by the display screen in the illuminating region is used for fingerprint identification, and an area of the illuminating region is smaller than an area of the fingerprint capturing region.
