Abstract

The invention provides a fingerprint unlocking method and a fingerprint unlocking device. The method comprises the steps that when external light is received, a designated light-emitting region of a display device is enabled to enter a first display mode; when the designated light-emitting region of the display device is stressed, the designated light-emitting region of the display device is enabled to enter a second display mode; when the designated light-emitting region of the display device enters the second display mode, fingerprint information of the designated light-emitting region is collected, and whether unlocking is allowed or not is judged according to the fingerprint information; if unlocking is allowed, the display device is controlled to be unlocked. The fingerprint unlockingmethod can achieve fingerprint unlocking of the full-screen display device by utilizing a virtual HOME key.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a fingerprint unlocking method and a fingerprint unlocking device. Background technique [0002] Now, the design of full-screen display has become the current mainstream trend, which makes the cancellation of the physical HOME key (start key) and the appearance of the virtual HOME key an inevitable trend. This brings about the diversified design of fingerprint unlocking. [0003] However, since the virtual HOME key needs to be integrated in the display area, the user cannot know the specific location of the HOME key when the screen is completely black. Therefore, in order to achieve full-screen display, using the virtual HOME key to unlock fingerprints is currently a problem that needs to be solved. one of the problems. SUMMARY OF THE INVENTION [0004] The present invention aims to solve at least one of the technical problems existing in the prior art, and prop...
