The invention discloses a fingerprint identification method and device based on a terminal screen, and is used for solving the problem that the terminal energy consumption is large in the prior art. The invention is applied to the fingerprint identification array which comprises N signal emission and reception terminals. Each signal emission and reception terminal is used for sending a detection signal and receiving a detection signal so as to obtain fingerprint image information of the user. The method comprises steps of receiving a fingerprint identification function starting instruction; according to the fingerprint identification function starting instruction, determining a fingerprint identification area on the terminal screen, wherein the fingerprint identification area and a first fingerprint identification subarray are at least partially overlapped, the first fingerprint identification subarray comprises M signal emission and reception terminals, and M is smaller than N; and starting the first fingerprint identification subarray to obtain the fingerprint image information of the user. The invention does not need to start the N signal emission and reception terminals of the entire fingerprint identification array, thus saving waste of the terminal energy by the N-M signal emission and reception terminals.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a terminal screen-based fingerprint identification method and identification device. Background technique [0002] Fingerprint recognition technology is a commonly used identity authentication method in daily life, and is widely used in a variety of terminals. At present, light-sensitive fingerprint recognition technology and capacitive pressure fingerprint recognition technology are the two most common fingerprint authentication technologies. [0003] However, both light-sensitive fingerprint recognition technology and capacitive pressure fingerprint recognition technology are aimed at the recognition of fingerprints on the skin layer of human fingers, so they are very easily affected by the surface state of fingerprints, for example, the ability to recognize wet fingers is very low . [0004] The radio frequency fingerprint identification technology is the third generat...
