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

[0044] 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.

[0045] According to the first embodiment of the present disclosure, a display module is proposed, which can be applied to electronic devices such as mobile phones and tablet computers. The scheme is illustrated as an example. Display modules include:

[0046] A display panel, the effective light-emitting area of ​​the display panel includes a light-transmitting layer and a light-shie...

Abstract

The present disclosure relates to a display module and an electronic device. The display module includes: a display panel, the effective light-emitting area of ​​the display panel includes a light-transmitting layer and a light-shielding layer arranged between adjacent light-transmitting layers; layer, which emits ultrasonic waves to the light-emitting side of the display panel; the ultrasonic receiving layer, which receives the ultrasonic waves reflected from the fingerprint to the display module; wherein, the ultrasonic emitting layer and the ultrasonic receiving layer are arranged correspondingly to the light-shielding layer at intervals; the processor, according to the ultrasonic receiving layer receiving The received ultrasonic wave determines the fingerprint pattern. According to the technical solution of the present disclosure, since both the ultrasonic emitting layer and the ultrasonic receiving layer have a layer structure, compared with the mechanical structure ultrasonic sensor in the related art, it can be conveniently arranged in a display module with the same layer structure, and its thickness is relatively The ultrasonic sensor due to the mechanical structure is much thinner, and it occupies less space in the thickness direction of the electronic equipment where the display module is located, which is conducive to the thinning of the electronic equipment.

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...
