Description

【Technical field】 [0001] The invention relates to the technical field of optical lenses, in particular to a fingerprint lens under a 4p wide-angle screen. 【Background technique】 [0002] In recent years, with the rise of smart phones, the demand for miniaturized photographic lenses is increasing, and the photosensitive devices of general photographic lenses are nothing more than Charge Coupled Device (CCD) or Complementary Metal Oxide Semiconductor Device (Complementary Metal Semiconductor). -OxideSemicondctor Sensor, CMOS Sensor) two kinds, and due to the improvement of semiconductor manufacturing technology, the pixel size of the photosensitive device is reduced, and the current electronic products have good functions, thin and short appearance as the development trend, so it has good The miniaturized wide-angle under-screen fingerprint lens with imaging quality has become the mainstream in the current market. [0003] In the related art, the current wide-angle screen fin...
