Abstract:
A heat dissipation module includes: a heat dissipation base material layer, provided with a first accommodating slot for accommodating a fingerprint sensor and a second accommodating slot for accommodating a flexible printed circuit, the fingerprint sensor being electrically connected to the flexible printed circuit, the first accommodating slot penetrating through the heat dissipation base material layer; and a light shielding buffer layer, on a side of the heat dissipation base material layer away from an opening of the second accommodating slot and provided with a hollowed-out area, an orthographic projection of the hollowed-out area on the heat dissipation base material layer being in the first accommodating slot, the hollowed-out area being configured to expose a photosensitive area of the fingerprint sensor, and the impedance of a surface of a side of the light shielding buffer layer away from the heat dissipation base material layer being 106Ω-1010Ω.
