Abstract
(EN)
The invention provides an optical fingerprint module, a screen assembly and an electronic device, which relate to the technical field of the fingerprint module. The optical fingerprint module comprises: a lens barrel, a lens, a light filter and a fingerprint identification chip. the fingerprint identification chip includes a first plane, The optical filter is arranged on the first plane, the lensbarrel comprises a connecting part and a mounting part remote from the connecting part, the lens is mounted on the mounting part, and the connecting part is arranged on the first plane of the fingerprint identification chip so that the distance between the lens and the fingerprint identification chip is a preset value. As that len is arranged in the len barrel and the lens barrel is directly connected with the fingerprint identification chip, the factors affect the distance between the fingerprint identification chip and the fingerprint identification chip are reduced, the precision of the optical fingerprint module can be effectively improved, and the defect rate of the product can be reduced.
