Abstract

The invention discloses a display device. The display device comprises a display screen, a fingerprint identification module and an induction member, wherein the fingerprint identification module is arranged on the display screen, the fingerprint identification module has a fingerprint contact surface, a pixel structure of the display screen has multiple pixel units used for displaying the display screen and multiple standby pixels used for emitting identification light for to-be-identified fingerprint, gaps are arranged between adjacent pixel units, the multiple standby pixels are respectively arranged in the multiple gaps, and the induction member is electrically connected with the display screen to make the standby pixels emit light when the to-be-identified fingerprint approaches a fingerprint contact surface. The display device is advantaged in that the multiple standby pixels are added on a display structure of the display screen, the induction member is utilized for inducting contact of the to-be-identified fingerprint to start the standby pixels as fingerprint identification light, so a light source needed during operation of the fingerprint identification module does not need light of the pixel units, and service life of the display screen is influenced. The invention further provides a mobile terminal.

Description

technical field [0001] The present invention relates to the field of electronic equipment, in particular to a display device and a mobile terminal. Background technique [0002] With the development of science and technology, at present, mobile phones and tablet computers are mainly unlocked by fingerprints. The existing fingerprint recognition devices are mainly capacitive fingerprint recognition devices, optical fingerprint recognition devices and thermal fingerprint recognition devices, while optical fingerprint recognition devices The device has become the most widely used fingerprint identification device due to factors such as reliable use and low price. [0003] The optical fingerprint identification devices used in mobile terminals in the prior art generally use the organic light-emitting layer of the display screen as light for fingerprint identification. light, its service life is relatively short, which is not conducive to the use of mobile terminals.
