Abstract

The invention provides a 4p wide-angle under-screen fingerprint lens, which sequentially comprises a first lens, a second lens, a third lens and a fourth lens from an object side to an image side, wherein the object side surface of the first lens is a convex surface; the image side surface of the first lens is a concave surface; the image side surface of the second lens is a convex surface; the image side surface of the third lens is a convex surface; the object side surface of the fourth lens is a concave surface; the image side surface of the fourth lens is a convex surface; the following relational expression is satisfied: 0.39 < CT1/(CT2+CT3+CT4) < 0.54. The 4p wide-angle under-screen fingerprint lens has the beneficial effects that the coverage area of the lens is large, and the shotscenery range is wide; the space depth feeling of a photographed picture can be increased; under-screen fingerprint recognition can greatly improve the screen-to-body ratio, operation is more sanitary, recognition is more stable, and the 4p wide-angle under-screen fingerprint lens is suitable for different environments.

Description

【Technical field】 [0001] The invention relates to the technical field of optical lenses, in particular to a 4p wide-angle under-screen fingerprint lens. 【Background technique】 [0002] In recent years, with the rise of smart phones, the demand for miniaturized photographic lenses has been increasing, and the photosensitive devices of general photographic lenses are nothing more than photocoupled devices (Charge Coupled Device, CCD) or complementary metal oxide semiconductor devices (Complementary Metal -OxideSemiconductor Sensor, CMOS Sensor), and due to the improvement of semiconductor manufacturing process technology, the pixel size of photosensitive devices has been reduced, and today's electronic products are developing with good functions and thin, light and small appearance. Therefore, it has good The miniaturized wide-angle under-display fingerprint lens with image quality has become the mainstream in the current market. [0003] In related technologies, the current ...
