摘要:
Provided is an electronic device. The electronic device includes a screen provided with a first polarizer, a second polarizer arranged below the screen, and an optical fingerprint identification module arranged below the second polarizer. The polarization direction of the first polarizer is the same with the polarization direction of the second polarizer. The first polarizer and the second polarizer are configured to filter a first optical noise. The second polarizer is configured to filter a second optical noise. The first optical noise is light from screen light of the screen and directing to the optical fingerprint recognition module. The second optical noise is light from the screen light, directing away from the optical fingerprint recognition module and reflected by a glass cover on an outer side of the screen.
