Abstract

The present disclosure relates to a display device, comprising: a backlight module and an array substrate, the array substrate includes: a substrate; a thin film transistor, a first area disposed on one side of the substrate; a photoelectric sensor, a second area disposed on one side of the substrate area, used to identify fingerprints according to the received invisible light; the backlight module includes a plurality of first light sources and at least one second light source corresponding to the second area, and the second light source is used to emit invisible light; the control chip when When the photoelectric sensor is in the state of fingerprint to be recognized, the thin film transistor corresponding to the second area and the second light source in the thin film transistor are controlled to be turned on. According to the technical solution of the present disclosure, by additionally arranging the second light source corresponding to the second area in the backlight module, invisible light can be emitted for the photoelectric sensor for identification, the influence of visible light in the external environment on the identification of fingerprints can be avoided, and the identification of fingerprints can be guaranteed. the accuracy of the results.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display device and an electronic device. Background technique [0002] With the diversification of encryption / decryption operations of smart terminals, fingerprints, an attribute that everyone has but varies from person to person, are getting more and more attention. Therefore, fingerprint identification modules are more and more commonly integrated in smart terminals. [0003] At present, the fingerprint identification module in the smart terminal (such as a mobile phone) mainly includes two types: the back and the front of the smart terminal. integrated together. [0004] However, no matter which method is mentioned above, the fingerprint recognition module needs to be manufactured separately, and then installed in the smart terminal, and the manufacturing process is relatively complicated. Contents of the invention [0005] The present disclosure provides ...
