Problems solved by technology

[0003] Fingerprint recognition technology has also become a standard technology for electronic equipment. With the development of fingerprint recognition technology, ultrasonic fingerprint recognition technology is more and more favored by suppliers. However, because ultrasonic fingerprint recognition modules are more sensitive to temperature, When the temperature changes, it is likely to reduce the fingerprint recognition efficiency

Abstract

The embodiment of the invention discloses a fingerprint identification method and a related product, the fingerprint identification methodis applied to electronic equipment, the electronic equipment comprises an ultrasonic fingerprint identification module and a touch display screen, and the ultrasonic fingerprint identification module is integrated below the touch display screen; the method comprises the steps that the battery temperature is detected every preset time interval, and when the absolute value of the difference value between the current battery temperature and the last battery temperature is larger than a preset threshold value, whether a preset object exists in a fingerprint collection area of the ultrasonic fingerprint recognition module to be attached to the touch display screen or not is detected; and when the preset object is not attached to the touch display screen in the fingerprint acquisition area, background image acquisition is carried out to obtain a target background image, and the target background image is taken as a current fingerprint background image. According to the embodiment of the invention, the fingerprint identification efficiency can be improved when the temperature changes.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a fingerprint identification method and related products. Background technique [0002] With the popularization and application of electronic devices (such as mobile phones, tablet computers, etc.), electronic devices can support more and more applications, and their functions are becoming more and more powerful. Indispensable electronic supplies. [0003] Fingerprint recognition technology has also become a standard technology for electronic equipment. With the development of fingerprint recognition technology, ultrasonic fingerprint recognition technology is more and more favored by suppliers. However, because ultrasonic fingerprint recognition modules are more sensitive to temperature, When the temperature changes, it is likely to reduce the fingerprint recognition efficiency.
