Problems solved by technology
[0002] With the widespread rise of full-screen mobile phones, fingerprint recognition technology has also been continuously improved. At present, fingerprint recognition technologies mainly include three categories: capacitive fingerprint recognition, optical fingerprint recognition and ultrasonic fingerprint recognition. Capacitive fingerprint recognition modules A mobile phone equipped with a full screen needs to install a capacitive fingerprint recognition chip under the screen, and the penetration capability of the capacitive fingerprint recognition chip itself limits the realization of its fingerprint recognition under the screen; the ultrasonic fingerprint recognition module has high penetration capability and high Anti-jamming ability However, as far as the current application of ultrasonic fingerprint recognition modules is equipped with full-screen mobile phones, the technology is not yet mature, the recognition speed is unstable, and the fingerprint recognition experience is poor; while optical fingerprint recognition modules do not have signal penetration. The problem is that as long as the screen can transmit light, the optical fingerprint chip can be placed under the screen to realize the application of the optical fingerprint recognition module equipped with a full-screen mobile phone
