Abstract

The invention discloses a screen, a fingerprint acquisition method and electronic equipment, which are used for solving the problem that the fingerprint acquisition method in the prior art is inconvenient for manufacturing and using the electronic equipment. The method comprises the steps that when it is detected that capacitance in the pressure sensing layer changes, the position of a target area, touched by a finger, in the screen is acquired; based on the operation that the finger touches the screen, an alternating current electric field is generated in the area, projected to the fingerprint acquisition layer, of the target area through the photosensitive resistance layer and the fingerprint acquisition layer; and acquiring a fingerprint profile diagram of the finger based on the impactof the metal powder on the fingerprint acquisition layer.

Description

technical field [0001] The invention relates to the technical field of fingerprint acquisition, in particular to a screen, a fingerprint acquisition method and an electronic device. Background technique [0002] With the rapid development of electronic devices, in order to protect the privacy, personal and property safety of users, many electronic devices provide security verification functions such as fingerprint recognition. [0003] Some of the existing fingerprint acquisition modules are arranged in the back cover or screen of the electronic device. If the fingerprint acquisition module is set in the physical button embedded in the rear shell, the rear shell needs to be drilled, which will not only affect the overall appearance of the electronic device, but also affect the hardness of the rear shell of the electronic device. The means of holes are also more complicated. However, if the fingerprint acquisition module is set in a small area under the screen, the fingerpr...
