Problems solved by technology

Correspondingly, when such a larger fingerprint recognition module is combined with an electronic device (such as a mobile phone), the thickness of the electronic device will be thicker, which is not conducive to the development of the electronic device in the direction of thinning and lightening.
[0005] For the fingerprint identification module using surface light source, the accuracy of collecting the fingerprint image formed by the light emitted by the surface light so...

Abstract

The invention discloses a display device and an electronic device. The display device is used for executing image display and is also used for executing biological characteristic information sensing.The display device comprises a plurality of point light sources, a touch screen, a controller, a plurality of photosensitive elements and a processing circuit, wherein the touch screen is used for determining the contact area of a target object on the display device; the controller is used for controlling the plurality of point light sources corresponding to the contact area to be turned on at different time to emit an optical signal to the target object; the plurality of photosensitive elements are used for receiving the optical signal reflected by the target object and converting the received optical signal into a corresponding electrical signal; and the processing circuit is used for determining the biological characteristic information of the target object according to the electrical signal. The electronic device comprises the display device.

Description

technical field [0001] The present invention relates to the field of biological feature identification, and in particular to a display device and an electronic device capable of performing full-screen biological feature information sensing. Background technique [0002] In related technologies, the principle of the optical fingerprint identification module mainly uses the reflection of light on the surface of the glass cover to identify the valley and ridge information of the fingerprint, because when the finger is pressed on the glass cover, the ridge of the fingerprint is in contact with the glass cover, and the The valley of the fingerprint is not connected with the glass cover, so that there is a large difference in the reflected light between the valley and the ridge of the fingerprint, and the reflected light is collected to realize the collection of the fingerprint. [0003] At present, optical fingerprint identification modules are mainly divided into two types, one ...
