Description

Method and terminal for screen recognition fingerprint

This application claims priority to Chinese Patent Application No. 201510200925.5, entitled "A Method and Terminal for Screen Recognition Fingerprint", filed on April 24, 2015, the entire contents of which is incorporated herein by reference. In the application.

Technical field

The present invention relates to the field of electronic technologies, and in particular, to a method and a terminal for recognizing a fingerprint on a screen.

Background technique

With the continuous development of terminal technologies, many terminals now have the function of fingerprint recognition. Most terminals use a button area on the panel (such as the Home button and the back button) for fingerprint recognition. For example: (1) The fingerprint sensor in the terminal is placed in the Home button for the recording and identification of fingerprint information. The surface of the Home button sensor is made of laser-cut sapphire crystal, which can accurately focus the fingerprint information and protect the sensor. The stainless steel ring around the sensor button monitors fingerprint information, activates the sensor and improves the signal-to-noise ratio. When the fingerprint sensor reads the fingerprint information, the terminal searches for the same fingerprint to unlock. (2) The fingerprint sensor is disposed in the back cover of the terminal. When detecting that the user presses the fingerprint sensor of the back cover of the terminal, the fingerprint sensor can record and recognize the fingerprint information. Additionally, a metal ring between the fingerprint recognition area and the rear case can be used to trigger the fingerprint sensor. However, in the prior art solution, if the terminal simultaneously sets password unlocking and fingerprint recognition, the user not only needs to operate the screen unlocking password, but also needs to operate the button to verify the fingerprint information, which reduces the user experience, and if the entire screen is used for unlocking The password or verification fingerprint information increases the power consumption of the terminal.
