Self-focusing lens array for fingerprint identification and mobile terminal

The invention discloses a self-focusing lens array for fingerprint identification and a mobile terminal. The self-focusing lens array is disposed below a pixel layer, and is formed by a plurality of self-focusing lenses which have erected real images and whose magnifying power is 1. Each self-focusing lens adopts the gap between pixel elements of the pixel layer as a clear aperture. The inventionis advantageous in that with the self-focusing lens array, the conjugate distance of the object image can be smaller than 7mm, system length can be greatly reduced, and the appearance of the mobile terminal and other functions will not be affected; the imaging process of the whole system can be completed only through the array, no other lens assistance is required, and mounting and adjusting process can be saved; the array area can meet the demand of the size of the mobile terminal screen, which means that imaging can be conducted on every part of the screen; the integral producing cost of thearray is not high, and th
