Problems solved by technology

[0004] For the existing system wake-up function, if the interrupt is not triggered by a finger at this time, it will cause a wrong wake-up of the system, resulting in unnecessary waste of power for the electronic device. Rubbing the screen will cause the system to be woken up frequently

Abstract

The embodiment of the invention discloses a system awakening method and device. The method comprises the following steps: when it is detected that conductor induction areas in a fingerprint module are touched by an external conductor, generating interruption signals corresponding to the conductor induction areas, wherein the minimum number of the conductor induction areas in the fingerprint module is two; acquiring first information, wherein the first information comprises the total number of all the interruption signals simultaneously generated and / or location information of the conductor induction areas generating the interruption signals; and when the first information meets preset conditions, awakening a system. The method and device adopting the technical scheme has the advantages that the system awakening reliability can be improved, and the possibility of faulty awakening can be reduced, so that the power consumption is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronic technology, and in particular, to a method and device for waking up a system. Background technique [0002] With the continuous advancement of electronic technology, fingerprint recognition, as a more secure identification method, has gradually become one of the standard configurations of various electronic devices. [0003] At present, the capacitive fingerprint recognition commonly used in the market cannot penetrate the screen glass because it is a press-type fingerprint sensor. As a result, electronic devices can only use the touch-press fingerprint recognition technology to wake up the system, but cannot use the hidden fingerprint (Underglass) recognition technology. Optical fingerprint recognition can penetrate the screen glass, and the price is relatively cheap, so that hidden fingerprint recognition technology can be used. Underglass optical fingerprint recognition came int...
