Display module and terminal

Abstract

The invention provides a display module and a terminal. The display module comprises a display panel which comprises a front and a back positioned on one side opposite to the front, the front is provided with a display area, the display module further comprises an optical fingerprint sensing element which is pasted on the back and arranged corresponding to the display area, and the optical fingerprint sensing element receives sensing light to recognize fingerprint information of an operating body of at least part of a display area corresponding to the optical fingerprint sensing element. The display module is high in screen-to-body ratio and good in user experience.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a display module and a terminal. Background technique [0002] With the development of information technology and electronic technology, portable terminals (such as mobile phones, tablets, etc.) , instant messaging, online payment, etc. People are increasingly dependent on terminals, and various private information are stored on portable terminals, which makes the security of portable terminals particularly important. In the prior art, a fingerprint identification device is installed in a portable terminal. Since a fingerprint is a texture formed by uneven skin on the surface of a finger, and fingerprint features are unique and stable, the fingerprint identification device can be used to identify a user, and in To a certain extent, it can ensure the safety of terminal use or increase the user experience of electronic equipment. [0003] Generally, the existing finge...

Problems solved by technology

[0003] Generally, the existing fingerprint identification device is arranged on a specific button area (such as the home key area) of the cover plate of the display module of the terminal, and the plane area of ​​the fingerprint identification device needs to be large enough to scan a considerable area of ​​fingerprints, so as to reduce the The misjudgment rate of fingerprint recognition makes it difficult to reduce the size of the key area, and the non-display area where the key area is located is also difficult to reduce, making it difficult to increase the screen-to-body ratio of the display module of the terminal.

In addition, the button area of ​​the cover plate of the display module of the existing terminal has an opening, so that the fingerprint identification device is exposed from the opening for user operation, and the opening leads to the overall strength and reliability of the cover plate. reduced, and the reliability of the display module of the terminal is low
