Terminal and control method thereof

Abstract

The embodiment of the invention relates to the technical field of electronic equipment, and discloses a terminal and a control method thereof. In the present invention, the terminal includes: a terminal body; a display module arranged above a fingerprint identification module; the display module comprises an identification area used for fingerprint identification. The display module is provided with an identification area, the identification area is opposite to a fingerprint identification module, the terminal further comprises a light-emitting unit used for providing illumination for the identification area and a backlight module which is located below the display module and provided with a groove, and the fingerprint identification module and the light-emitting unit are located in the groove; a light homogenizing piece is further arranged between the light emitting unit and the display module, the light incident face of the light homogenizing piece faces the light emitting unit, andthe light emergent face of the light homogenizing piece faces the recognition area. The success rate of fingerprint identification can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electronic equipment, and in particular to a terminal and a control method thereof. Background technique [0002] At present, in order to protect the user's information security, the use of fingerprint recognition functions on mobile phones is becoming more and more common, such as for mobile phone unlocking and mobile payment, which not only protects user information security, but also brings great convenience to users sex. Among them, the screen fingerprint recognition technology means that the user can realize screen recognition directly by touching a certain display area of ​​the screen. In the prior art, the fingerprint identification module is generally arranged under the screen, and when the finger is placed on the screen, the fingerprint identification module is used to identify the light reflected by the finger, thereby realizing screen fingerprint identification.

AI Technical Summary

Problems solved by technology

[0003] The inventors have found that there are at least the following problems in the prior art: for the under-screen fingerprint technology of the LCD display screen, since the LCD itself does not emit light and the light transmittance is low, the problem of screen fingerprint identification failure is prone to occur, and the success rate of fingerprint identification is not high. high
