1. A display panel, comprising:

  • a display module comprising a first substrate and a first polarizer disposed on the first substrate, wherein the first substrate has an inner side facing the first polarizer and an opposite outer side, the first polarizer has an inner side facing the first substrate and an opposite outer side, and a light-exiting surface of the display module is arranged on the outer side of the first polarizer;

    a fingerprint recognition module disposed on the outer side of the first substrate and comprising a fingerprint recognition layer and a second polarizer, wherein the fingerprint recognition layer has an inner side facing the display module and an opposite outer side, and the second polarizer is disposed on the inner side of the fingerprint recognition layer; and

    a light source disposed on the inner side of the first polarizer,wherein the fingerprint recognition layer is configured to recognize fingerprint based on fingerprint signal light, the fingerprint signal light being light emitted from the light source and then reflected to the fingerprint recognition layer by a touch object,the first polarizer is engaged with the second polarizer, such that the fingerprint signal light is transmitted through the first polarizer and the second polarizer without a light intensity loss, andthe second polarizer is configured to reduce the light intensity of fingerprint noise light, the fingerprint noise light being light other than the fingerprint signal light.
