Problems solved by technology

However, when the user's pressing area deviates from the sensing area of ​​the fingerprint device, the fingerprint image collected by the fingerprint device is incomplete. If such a fingerprint image is used by the user for entry or identification, it may cause operation failure and affect user experience.

Embodiment Construction

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0034] As smart terminals enter the era of full screens, the space for fingerprint buttons on the front of the screen is being squeezed. Therefore, solutions for under-display or in-display fingerprint recognition systems have emerged as the times require. The so-called under-screen or in-screen fingerprint recognition system means that the fingerprint device is installed under the screen or integrated into the screen, so as to realize the fingerprint recognition operation inside the screen display area.

[0035] As a common application scenario, the press detection method of the fingerprint recognition system involved in the embodiment of the present application can be applied to smartphones, tablet computers, multimedia devices, game consoles, and other mobile terminals wit...

Abstract

Embodiments of the present application provide a press detection method and device for a fingerprint identification system, and a terminal device. The fingerprint recognition system includes a screenand a fingerprint device. The sensing area of the fingerprint device is at least partially located in a display area of the screen. The method includes: obtaining a pressing area of a fingerprint pressing operation of the screen; determining an overlapping ratio of the pressing area of the fingerprint pressing operation and the sensing area of the fingerprint device; and according to the overlapping ratio, determining the validity of the fingerprint pressing operation, wherein the validity of the fingerprint pressing operation includes valid fingerprint press or invalid fingerprint press. Themethod, the device and the terminal device of the embodiments of the present application can filter out invalid fingerprint press caused by incomplete pressing during the user's use, thereby effectively preventing the fingerprint template collected by the fingerprint recognition system from being incomplete or fingerprint identification failures and other issues due to incomplete pressing.

Description

technical field [0001] The present application relates to the field of fingerprint identification, and in particular to a press detection method, device and terminal equipment of a fingerprint identification system. Background technique [0002] For the current terminal equipment using the under-screen fingerprint recognition system, the fingerprint device is assembled on the back of the screen. When using the fingerprint recognition function, the screen will notify the fingerprint device to collect the fingerprint image after sensing the user's pressing event in the fingerprint sensing area, and complete the fingerprint entry. or identify operations. However, when the user's pressing area deviates from the sensing area of ​​the fingerprint device, the fingerprint image collected by the fingerprint device is incomplete. If such a fingerprint image is used by the user for entry or identification, it may cause operation failure and affect user experience. Contents of the inv...
