Embodiment Construction

[0058] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0059] When the fingerprint is unlocked, the processor of the smart terminal sends a highlight mode command to the display driver chip, so that the fingerprint display area enters the highlight mode, and then the processor internally counts and sends a fingerprint collection command after a period of time to notify the fingerprint chip to collect fingerprints to complete Unlock operation.

Abstract

The invention relates to a fingerprint acquisition method and device and a medium. The method is applied to a terminal provided with a display screen, and comprises the following steps: when it is detected that the display screen is pressed, starting a highlight mode of the display screen; and after determining that the display screen enters the highlight mode, starting a fingerprint acquisition operation. By adopting the method, the fingerprint acquisition module can be prevented from starting to acquire fingerprints when the display screen does not enter the highlight mode, so that fingerprint acquisition failure is avoided.

Description

technical field [0001] The present disclosure relates to the technical field of intelligent terminals, and in particular to a fingerprint collection method, device and medium. Background technique [0002] With the application of smart terminals, such as mobile phones and PADs, people are becoming more and more aware of the security of smart terminals, and the application of fingerprint unlocking is also becoming more and more extensive. Currently, the fingerprint unlocking methods used in OLED mobile phones are Optical fingerprint unlocking, that is, the user presses the display with a finger. After the system detects the finger pressing action, it notifies the driver chip to increase the local brightness of the display so that the fingerprint unlocking area enters a high-brightness mode, and at the same time notifies the fingerprint unlocking chip to collect finger fingerprint information. The entered information is matched, and the unlocking can be completed after the mat...
