US 10,482,309 B2 · Method and apparatus for controlling fingerprint acquisition based on a display screen and electronic device

Abstract

The present application discloses a method for controlling fingerprint acquisition based on a display screen and a related apparatus, which are applied to a display screen with a fingerprint acquisition function. In the disclosure, by detecting a fingerprint acquisition triggering instruction generated in an electronic device in real time, a preset fingerprint acquisition region of the display screen is controlled to emit light and a fingerprint sensor is triggered to acquire a fingerprint image, if and only if the fingerprint acquisition triggering instruction is detected. When the fingerprint acquisition triggering instruction does not exist, the display screen is not affected and the fingerprint sensor is in a non-operating state so as to save energy. Moreover, only the preset fingerprint acquisition region on the display screen is controlled to perform the fingerprint acquisition, and other regions on the display screen are not affected in fingerprint acquisition, therefore, the original display or the black screen state of the display screen is not affected, and it is ensured that the user can accurately touch the region with a finger to acquire a fingerprint image accurately and quickly. In this way, the cost of hardware integration may be reduced, the appearance may be simplified and the user experience may be improved.

Dependent claims

A method for controlling fingerprint acquisition based on a display screen, which is applied to an electronic device, wherein the electronic device comprises at least a display screen, and a fingerprint sensor installed under the display screen corresponding to a preset fingerprint acquisition region of the display screen, the method comprises:

detecting a fingerprint acquisition triggering instruction from a user;
controlling the preset fingerprint acquisition region to emit light to illuminate a finger surface, according to the fingerprint acquisition triggering instruction detected;
and
triggering the fingerprint sensor to acquire a fingerprint image,
wherein the fingerprint acquisition triggering instruction comprises at least one of:
a first display screen wake-up instruction generated when it is detected that a power key or a start key of the electronic device is pressed by a user in a black screen state;
a second display screen wake-up instruction generated when a touch sensing apparatus detects that a first touch operation is performed by the user in a black screen state, wherein the first touch operation comprises any one of performing a single click on the display screen, performing a continuous click on the display screen and touching the display screen for a long time, and the touch sensing apparatus is disposed in the electronic device to detect a touch operation of the user on the display screen;
and
a display screen wake-up and authentication instruction generated when the touch sensing apparatus detects that a second touch operation is performed by the user in a black screen state, wherein the second touch operation comprises any one of performing a single click or continuous click on the preset fingerprint acquisition region and touching the preset fingerprint acquisition region for a long time.
