A fingerprint detecting device and electronic equipment can increase strength of a light signal received by the device and improves fingerprint image quality and identification effect. The fingerprintdetecting device is arranged below the display screen of the electronic equipment and comprises the components of a micro-lens array which comprises a plurality of circular micro-lenses, wherein eachcircular micro-lens in the plurality of circular micro-lenses are adjacent with six circular micro-lenses, and the connecting lines of the centers of the six circular lenses form a regular hexagon; apixel array which is arranged below the micro-lens array and comprises a plurality of pixels, the plurality of pixels are in one-to-one correspondence with the plurality of circular micro-lenses, thepixels are used for receiving a light signal which is focuses by the corresponding circular micro-lens, and the light signal is the light signal after finger reflection or scattering and is used fordetecting the fingerprint information of the finger; the plurality of pixels are N sets of pixels, each set of pixels in the N sets of pixels comprises M adjacent pixels, and the light signal which isreceived by the M pixels is used for forming one pixel in the fingerprint image of the finger, wherein M and N are positive integers which are higher than 1.
Description
technical field [0001] The present application relates to the technical field of optical fingerprints, and more specifically, to a fingerprint detection device, method and electronic equipment. Background technique [0002] The traditional Organic Light-Emitting Diode (OLED) under-screen fingerprint optical system has been mass-produced in smart phones and other electronic products. The fingerprint detection device receives and performs fingerprint identification. However, due to the limited light intensity of the OLED screen and the absorption and scattering of the light signal by the finger, the light signal reflected by the finger received by the traditional fingerprint detection device is weak, the quality of the fingerprint image is low, and the fingerprint recognition effect is poor. [0003] Therefore, how to increase the intensity of the optical signal received by the fingerprint detection device to improve the fingerprint image quality and recognition effect is an ...
