1. a kind of optical fingerprint identification device characterized by comprisingLight detecting portion, including light detection array, the light detection array include multiple pixel units;

  • Wave filtering layer, for filtering the optical signal of non-targeted wave band, through the optical signal of target wave band, the wave filtering layer is describedThe filter film formed above multiple pixel units of light detection array, and the wave filtering layer and the light detection array oneIt rises and is integrated in photoelectric sensor chip;

    First shading layer is formed in above the wave filtering layer, wherein first shading layer is provided with multiple light passing apertures;

    First microlens array is set to above first shading layer;

    Wherein, first microlens array is used to converge to optical signal multiple light passing apertures of first shading layer, instituteIt states optical signal and is transmitted to the light detection array by multiple light passing apertures of first shading layer.
