Problems solved by technology
[0003] The accuracy of the current ultrasonic fingerprint recognition is affected by the internal environment of the electronic device. After the ultrasonic wave is emitted, it will be emitted into the electronic device. The ultrasonic wave reflected by the device inside the electronic device will interfere with the ultrasonic fingerprint recognition module.
Therefore, it is necessary to protect the ultrasonic fingerprint recognition module against electromagnetic interference. The current technical means is to wrap a protective cover around the module. However, the protective cover needs to be spaced from the module to form a space with an air layer, so that the ultrasonic Rapid decay in the air layer
The scheme of setting up the protective cover in the prior art makes the overall thickness of the fingerprint identification module and the protective cover very thick, generally reaching 645 μm, which is not conducive to the thinning and thinning of electronic equipment

The embodiment of the invention provides a fingerprint identification assembly and an electronic device, the fingerprint identification assembly comprises a fingerprint sensor and a protective layer,the protective layer is arranged at the bottom, opposite to the top, of the fingerprint sensor, and the surface of the top is a fingerprint identification sensing surface; the fingerprint sensor is used for transmitting and identifying ultrasonic waves, and the protective layer shields electromagnetic interference. By arranging the protective layer, electromagnetic interference can be shielded; besides, the protective layer can be made to be very thin, an air layer does not need to be arranged, the overall thickness of the fingerprint identification assembly can be remarkably reduced, and thethickness of the electronic equipment can be made to be thinner.
Description
technical field [0001] The invention belongs to the technical field of fingerprint identification, and in particular relates to a fingerprint identification component and electronic equipment. Background technique [0002] Ultrasonic fingerprint recognition, as an emerging fingerprint recognition technology, has become the two main off-screen fingerprint recognition solutions together with optical fingerprint recognition. The ultrasonic fingerprint identification module emits ultrasonic waves, the ultrasonic waves pass through the display screen and the glass cover to detect user fingerprints, and the ultrasonic waves are reflected back to the ultrasonic fingerprint identification module to be received and identified. [0003] The accuracy of the current ultrasonic fingerprint recognition is affected by the internal environment of the electronic device. After the ultrasonic wave is emitted, it will be emitted into the electronic device, and the ultrasonic wave reflected by t...
