Abstract

The present invention discloses a display module and an electronic device. The display module comprises a display device, wherein the display device comprises a display panel for performing image display, and the display panel comprises a plurality of display pixels; and a photosensitive device, wherein the photosensitive device comprises a photosensitive panel, and the photosensitive panel and the display panel are arranged in a stacked manner for obtaining predetermined biometric information of a target object touching or approaching the display module by sensing an optical signal. The display device further comprises a display driving circuit, for driving the display pixels to be lit in a time-sharing manner when the photosensitive panel performs the biometric information sensing. The electronic device comprises the display module.

Description

technical field [0001] The invention relates to a display module and electronic equipment for realizing biometric information sensing. 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 4...
