Abstract

The invention provides a device, module, equipment and system for fingerprint identification. In the device, the first lens array and the second lens array are combined and fixed to form a double-lens structure, which improves the integration and reduces the cost of the device. The volume, and the object distance and the image distance can be adjusted without affecting the accuracy of the adjustment, which improves the applicability of the device.

Description

technical field [0001] The present invention relates to the technical field of identity recognition. More specifically, it relates to devices, modules, equipment and systems for fingerprint identification. Background technique [0002] The optical fingerprint recognition technology used in OLED displays, including mobile phones and other mobile terminals, is still immature, and the current "under-screen fingerprint" technology is not perfect. Coupled with the development of full-screen technology, the demand for under-screen fingerprints is increasing. higher. SUMMARY OF THE INVENTION [0003] In order to solve at least one of the above technical problems, a first aspect of the present invention provides an apparatus for fingerprint identification, comprising: [0004] a first lens array, including a plurality of lenses; [0005] a second lens array disposed opposite the first lens array, including a plurality of lenses; and [0006] a light-shielding element arranged ...
