Title: DISPLAY SCREEN-BASED FINGERPRINT COLLECTION CONTROL METHOD AND APPARATUS, AND ELECTRIC DEVICE
Abstract:
Disclosed are a display screen-based fingerprint collection control method, and a related apparatus, being applied to a display screen having a fingerprint collection function. The method comprises: detecting a fingerprint collection trigger instruction generated in an electric device in real time; when and only when the fingerprint collection trigger instruction is detected, controlling a pre-set fingerprint collection region of a display screen so that same emits light and triggering a fingerprint sensor so that same collects a fingerprint image; and when there is no fingerprint collection trigger instruction, the display screen being not affected, and the fingerprint sensor being in a non-working state, thereby achieving the purpose of energy saving. Only a pre-set fingerprint collection region on a display screen is controlled for a fingerprint collection process, and the other regions on the display screen are not affected by the fingerprint collection process, so that an original display or black-screen state of the display screen is not affected, and it is also ensured that a user correctly stamps a finger, so as to accurately and quickly collect a fingerprint image; in addition, hardware integration costs can be reduced, the appearance can be simplified, and the use experience can be improved.
