Abstract

The embodiment of the invention provides an ultrasonic sensor module, a display screen module and electronic equipment, and the ultrasonic sensor module comprises: a piezoelectric material layer whichcomprises a first region and a second region which are adjacent to each other; an electrode layer which is connected with the piezoelectric material layer, wherein the electrode layer is used for applying a driving signal to the piezoelectric material layer so as to drive a first region of the piezoelectric material layer to emit an ultrasonic signal with a first frequency and drive a second region of the piezoelectric material layer to emit an ultrasonic signal with a second frequency, and the first frequency is smaller than the second frequency. The ultrasonic sensor module can achieve a distance detection function and a fingerprint recognition function at the same time. Moreover, when the ultrasonic sensor module achieves distance detection and fingerprint recognition, ultrasonic signals can penetrate through the display screen module, so that a non-display area does not need to be independently arranged on the display screen module, and the screen-to-body ratio of the display screen module can be increased.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to an ultrasonic sensor module, a display module and electronic equipment. Background technique [0002] With the development of electronic technology, electronic devices such as smart phones are used more and more frequently in users' lives. For example, a user can realize a call function, a shopping function, a payment function, and the like through an electronic device. [0003] Usually, when an electronic device is in a call, the electronic device needs to detect the distance between the user's face and the electronic device, so as to control the display screen of the electronic device to turn on or off, thereby preventing the user's face from touching the electronic device. The display may cause misoperation. In scenarios where user identity needs to be verified, such as unlocking electronic devices, realizing shopping functions through electronic devices, and r...
