Abstract

The invention discloses a terminal device and a fingerprint identification method and device, and belongs to the field of a smart terminal. The terminal device comprises a processing chip, a fingerprint sensor and a temperature collection assembly. The processing chip is electrically connected with the fingerprint sensor and the temperature collection assembly. The processing chip is used for collecting a fingerprint signal through the fingerprint sensor and collecting a temperature signal through the temperature collection assembly, determining a compensation coefficient corresponding to the temperature signal, compensating the fingerprint signal according to the compensation coefficient and carrying out fingerprint identification according to the compensated fingerprint signal. The problem that the whole fingerprint identification process is relatively long due to the fact that in order to avoid an identification error of the fingerprint signal resulting from the environment temperature, the processing chip needs to adjust hardware parameters and processing algorithms continuously and collect the fingerprint signal for many times for identification is solved, the collection times of the fingerprint signal is reduced, the fingerprint identification process is simplified, and the fingerprint identification speed is accelerated.

Description

technical field [0001] The present disclosure relates to the field of intelligent terminals, and in particular to a terminal device, a fingerprint identification method and a device. Background technique [0002] With the development of fingerprint identification technology, terminal devices such as smart phones, tablet computers and attendance machines can be embedded with fingerprint sensors, and terminal devices collect user's fingerprint signals through fingerprint sensors, and then identify the fingerprint signals to realize screen unlocking. , account login and fingerprint time attendance and other functions. [0003] Since the ambient temperature will affect the collection result of the fingerprint signal, for the same finger, the fingerprint signals collected by the terminal device at different temperatures may be different. In related technologies, in order to avoid the problem of errors in the identification of collected fingerprint signals due to ambient temperat...
