Abstract

The invention provides an under-screen fingerprint sensor, a fingerprint image generation method and electronic equipment. The under-screen fingerprint sensor comprises: a plurality of lenses defininga part of a fingerprint acquisition area corresponding to the lenses as sub-acquisition areas, the adjacent sub-acquisition areas being at least partially overlapped, the lenses being used for enabling light belonging to a vertical incident angle range in light incident from the sub-acquisition areas to be emitted to focuses of the lenses; and an image sensor which is arranged on the light emitting sides of the lenses, wherein a plurality of light receiving areas and an image generating unit are arranged in the image sensor, the light receiving areas are used for receiving light passing through the focuses of the lenses, and the image generating unit is used for receiving pixel values of the light receiving areas and combining the pixel values, the display panel is provided with a first lower surface far away from one side of the transparent cover plate, and the vertical incident angle range comprises an incident angle of light vertically incident to the first lower surface or an incident angle of light obliquely incident to the first lower surface and refracted to a focal point.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a fingerprint sensor, a method for generating a fingerprint image and electronic equipment. Background technique [0002] The fingerprint sensor takes pictures of fingerprints and converts them into electrical signals. In order to capture a fingerprint image, a conventional optical fingerprint sensor has an optical system that irradiates light onto the fingerprint and reflects the light. However, since optical systems such as prisms, mirrors, and lenses usually have a relatively large volume, it is difficult to miniaturize an electronic device with an optical fingerprint sensor. Contents of the invention [0003] The main purpose of the present invention is to provide a fingerprint sensor, a method for generating a fingerprint image and an electronic device, so as to solve the problem that it is difficult to miniaturize the fingerprint sensor in the prior art. [0004] In ord...
