Abstract

The invention provides a fingerprint sensor control method and a mobile terminal. The use of the mobile terminal applied to a fingerprint identifying sensor includes steps of detecting if skin contacts the fingerprint identifying sensor when the mobile terminal is under a screen locking state; when the fingerprint identifying sensor contacted with skin is detected, awakening the mobile terminal and obtaining a current inclination angle of the mobile terminal; according to the current inclination angle of the mobile terminal, judging if the mobile terminal is under a cross screen state, wherein the fingerprint sensor is easier to contact user palm when the mobile terminal is under the cross screen state in comparison to the condition when the mobile terminal is under the vertical screen state; when the mobile terminal is under the cross screen state, closing the fingerprint sensor.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint sensor control method and a mobile terminal. Background technique [0002] Currently, mobile terminals with fingerprint sensors are widely used. For example, electronic devices such as smart phones are usually equipped with fingerprint sensors. When the user wants to unlock the mobile terminal, he puts his finger on the fingerprint sensor, and the fingerprint sensor collects the user's fingerprint information, and compares the collected user's fingerprint information with the preset fingerprint information pre-stored in the mobile terminal. For comparison, when the fingerprint information of the user matches the preset fingerprint information pre-stored in the mobile terminal, the mobile terminal is unlocked; otherwise, the mobile terminal is not unlocked. However, when the user uses the mobile terminal, when the mobile terminal is in a specific ...
