Problems solved by technology

However, large-area fingerprint recognition also brings more serious false touch problems than single-point fingerprint recognition.
When the user's mobile phone is placed in the pocket, since the mobile phone has a larger unlocking area, when the finger accidentally touches the unlocking area, the probability of accidentally touching the unlocking is greatly increased, and the power consumption of the screen is also increased.

Embodiment Construction

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0035] A fingerprint unlocking method and device, an electronic device, and a computer-readable storage medium proposed in the embodiments of the present invention are described below with reference to the accompanying drawings.

[0036] Taking the fingerprint unlocking method applied to a mobile terminal as an example, when the user puts the mobile terminal in a place with relatively low ambient light (such as a pocket of clothes), it is very easy to unlock the device due to a finger touch by mistake, causing troubles in use, or ...

Abstract

The invention discloses a fingerprint unlocking method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: obtaining the current ambient light brightness when a touch signal of a user is received; when the current ambient light brightness is smaller than a preset brightness threshold value, performing reduction processing on a screen fingerprint detection area; when a touch position corresponding to the touch signal is located in the reduced screen fingerprint detection area, lightening a screen corresponding to the touch position, and obtaining fingerprint information of the user; and performing fingerprint unlocking according to the fingerprint information of the user. Therefore, according to the method, the screen fingerprint detection area is processed according to the ambient light brightness, under the condition that the advantage of large-area under-screen fingerprint unlocking is utilized, finger mistaken touch unlocking caused by a large-area fingerprint recognition area can be effectively avoided, and meanwhile the power consumption of the screen can be reduced.

Description

technical field [0001] The present invention relates to the technical field of fingerprint identification, in particular to a fingerprint unlocking method, a fingerprint unlocking device, an electronic device and a computer-readable storage medium. Background technique [0002] At present, more and more terminal manufacturers are pursuing the display effect and sense of technology on the front of mobile phones, making full-screen mobile phones the most fashionable products at present. In order to achieve a full-screen display effect, in addition to the screen design, the fingerprint recognition technology under the screen is also indispensable. The under-screen fingerprint technology cancels the physical fingerprint recognition button and hides the sensor module under the display. The main implementation method of the under-screen fingerprint recognition technology is: the fingerprint recognition module is placed under the display screen. When the user presses the display s...
