Problems solved by technology

Since ultrasonic sensors and physical buttons need to be installed at the position of the physical buttons, and the thickness of the ultrasonic sensor of the mechanical structure is relatively large, the space under the upper cover of the mobile phone will be larger, which will easily lead to the instability of the overall structure of the mobile phone, and is not conducive to Thinning and Lightening of Mobile Phones

Embodiment Construction

[0041] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0042] figure 1 It is a schematic structural diagram of a display module shown according to an exemplary embodiment. The display module can be applied to electronic devices such as mobile phones and tablet computers. The following mainly uses the display module in mobile phones as an example. The technical solution is illustrated as an example. Such as figure 1 As shown, the display...

Abstract

The present disclosure relates to a display module and an electronic device. The display module comprises: a display panel; an ultrasonic wave emitting layer, which is arranged outside an effective light emitting region along the edge of the effective light emitting region of the display panel, and is used for emitting the ultrasonic wave to a light exit side of the display panel; an ultrasonic wave receiving layer, which is used for receiving the ultrasonic wave reflected from the fingerprint to the display module; and a processor, which is used for determining a fingerprint pattern according to the ultrasonic wave received by the ultrasonic wave receiving layer. According to the display module and the electronic device disclosed by the present disclosure, simplification of the manufacturing process of the display module is facilitated, and compared with the ultrasonic sensors with the mechanical structure in the related art, the thickness of the display module is much thinner than the ultrasonic sensors with the mechanical structure, so that the occupation space of the display module in the thickness direction of the electronic device is relatively small, and the thinning of the electronic device is facilitated.

Description

technical field [0001] The present disclosure relates to the field of distance sensing technology, in particular to a display module and an electronic device. Background technique [0002] At present, the ultrasonic fingerprint identification structure in mobile phones is generally an ultrasonic sensor with a mechanical structure arranged on a physical button. Since ultrasonic sensors and physical buttons need to be installed at the position of the physical buttons, and the thickness of the ultrasonic sensor of the mechanical structure is relatively large, the space under the upper cover of the mobile phone will be larger, which will easily lead to the instability of the overall structure of the mobile phone, and is not conducive to The thinning and lightening of mobile phones. Contents of the invention [0003] The disclosure provides a display module and an electronic device to solve the deficiencies in related technologies. [0004] According to a first aspect of an e...
