Abstract

The invention discloses a display module and electronic equipment, and belongs to the field of communication equipment.The display module comprises an acoustic-electric conversion layer, a plurality of first electrodes, second electrodes and third electrodes, the first electrodes and the third electrodes are arranged on the two opposite sides of the acoustic-electric conversion layer, and the second electrodes are arranged on the two opposite sides of the acoustic-electric conversion layer at intervals; in the thickness direction of the acoustic-electric conversion layer, the projections of the first electrodes and the projections of the third electrodes are distributed at intervals, and one first electrode or one third electrode is arranged opposite to at least two second electrodes; in a touch control mode, the first electrodes are driving electrodes, the third electrodes are receiving electrodes, and the first electrodes and the third electrodes are used for detecting touch control capacitance; and in the ultrasonic mode, the first electrode and the third electrode which are correspondingly provided with the second electrode are driving electrodes used for driving the acoustic-electric conversion layer to generate ultrasonic waves, and the second electrode is a receiving electrode used for receiving the reflected ultrasonic waves. The thickness of the display module with the fingerprint identification function is relatively small.

Description

technical field [0001] The application belongs to the technical field of communication equipment, and in particular relates to a display module and electronic equipment. Background technique [0002] With the development of technology, more and more technologies are applied to electronic devices. For example, compared to previous electronic devices that required a separate arrangement of a fingerprint identification module outside the display screen, a fingerprint identification module has been deployed in the area where the display screen is located in the related art. However, in the current combination scheme of the display screen and the fingerprint identification module, the fingerprint identification module is arranged under the display screen, which leads to a relatively large overall thickness of the electronic device. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a display module and an electronic devic...
