Problems solved by technology

[0003] However, the above-mentioned optical fingerprint identification module can only be installed in a predetermined area of ​​the mobile terminal, such as the non-display area of ​​the mobile terminal, and the fingerprint identification can only be performed by touching the predetermined area, so the use is still limited.

Abstract

The present invention discloses a display module biometric information sensing method. The method comprises: S1, when a target object touches or approaches a display module and triggers biometric information sensing, controlling display pixels of a display panel to be lit in a time-sharing manner so that optical signals emitted by the display pixels can reach the target object; S2, providing scanning drive signals to a plurality of photosensitive units to drive the photosensitive units to receive the optical signals reflected by the target object, and converting the received optical signals into corresponding electrical signals; and S3, obtaining predetermined biometric information of the target object according to the electrical signals output by the plurality of photosensitive units.

Description

technical field [0001] The invention relates to a biometric information sensing method of a display module. Background technique [0002] At present, biometric information sensors, especially fingerprint recognition sensors, have gradually become standard components of electronic products such as mobile terminals. Since the optical fingerprint recognition sensor has a stronger penetration capability than the capacitive fingerprint recognition sensor, an optical fingerprint recognition module applied to a mobile terminal has been proposed. Such as figure 1 As shown, the optical fingerprint identification module includes an optical fingerprint sensor 400 and a light source 402 . Wherein, the optical fingerprint sensor 400 is disposed under the protective cover 401 of the mobile terminal. The light source 402 is disposed adjacent to one side of the optical fingerprint recognition sensor 400 . When the user's finger F touches the protective cover 401, the light signal emitte...
