Embodiment 1

[0020] figure 1 A schematic flowchart of a fingerprint sensor-based display screen wake-up method provided in Embodiment 1 of the present invention, the method can be executed by a fingerprint sensor-based display screen wake-up device, wherein the device can be implemented by software and / or hardware, and generally can be integrated in the mobile terminal. like figure 1 As shown, the method includes:

[0021] Step 101. When the display screen of the mobile terminal is in a dormant state, if it is detected that the fingerprint sensor configured in the mobile terminal is pressed, acquire an image of the pressed object through the fingerprint sensor.

[0022] Exemplarily, the mobile terminal in this embodiment may specifically be a device such as a mobile phone, a smart watch, a tablet computer, and a notebook computer equipped with a fingerprint sensor. Preferably a smartphone.

[0023] Exemplarily, usually, when the mobile terminal is in the dormant state, the system and t...

Embodiment 2

[0036] figure 2 It is a schematic flowchart of a method for waking up a display screen based on a fingerprint sensor provided by Embodiment 2 of the present invention. This embodiment is based on the above-mentioned embodiment, and optimizes "determining whether to wake up the display screen according to the judgment result": when the judgment result is When the pressed object image is not a fingerprint image, keep the display screen in a dormant state; when the pressed object image is determined to be a fingerprint image according to the judgment result, match the fingerprint image with a preset fingerprint template, and wake up the display screen if the matching is successful.

[0037] Specifically, the method of this embodiment includes the following steps:

[0038] Step 201, when the display screen of the mobile terminal is in a dormant state, if it is detected that the fingerprint sensor configured in the mobile terminal is pressed, acquire an image of the pressed object...

Abstract

The embodiment of the invention discloses a display screen wake-up method, device and mobile terminal based on a fingerprint sensor. The method includes: when the display screen of the mobile terminal is in a dormant state, if it is detected that the fingerprint sensor configured in the mobile terminal is pressed, the image of the pressed object is obtained through the fingerprint sensor; whether the image of the pressed object is a fingerprint image is determined according to the judgment result. Whether to wake up the display. In the embodiment of the present invention, by adopting the above technical solution, when the user does not actively wake up the display screen, body parts such as palms or other objects that can form capacitance with the fingerprint sensor may press the fingerprint sensor. At this time, the image of the pressed object is obtained through the fingerprint sensor , and determine whether the image of the pressed object is a fingerprint image, and then determine whether to wake up the display screen according to the judgment result, which can effectively prevent the display screen from being woken up due to false triggering, save system power consumption, thereby prolonging the standby time and improving user experience.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile terminals, in particular to a method and device for waking up a display screen based on a fingerprint sensor, and a mobile terminal. Background technique [0002] At present, the size of the display screen of the mobile terminal is getting larger and larger, and users spend a lot of time using the mobile terminal every day, so the power consumption of the mobile terminal has become the most concerned issue of the users. In addition, in order to protect the user's information security, the current mobile terminal is usually integrated with a fingerprint sensor, which is used in scenarios that require fingerprint authentication, such as waking up or unlocking the terminal from a black screen, unlocking applications, and fingerprint payment. [0003] Most of the fingerprint sensors configured in mobile terminals are capacitive fingerprint sensors. When a user unlocks a mobile...
